Insomnia

• Defined as subjective dissatisfaction with sleep duration or quality - difficulty initiating, maintaining, or early-morning awakening with inability to return to sleep
• More common in women and older people
• Typically associated with excessive mental arousal rather than bodily disorder
• Common in: depression, generalised anxiety disorder, panic, phobias, hypochondriasis, personality disorders, mania, acute schizophrenia, substance use disorders

• Early insomnia (initial): Difficulty falling asleep - characteristic of anxiety/arousal states. Mind dwelling on affect-laden experiences, rehearsing problem-solving
• Middle insomnia: Frequent awakenings - characteristic of anxiety disorders, neurotic disorders (Jovanovic 1978: neurotic patients spent more time lying awake, had shorter deep sleep, more sensitive to unfamiliar surroundings)
• Late insomnia (terminal / early-morning awakening): Characteristic of depressive phase of affective disorders. Often associated with marked diurnality of mood - most severe despondency in the early morning
• Reduced sleep requirement in mania - often not complained of by the patient but marked

• Medications: psychotropics, stimulants, SSRIs (cause sleep fragmentation and vivid dreams)
• Substance ingestion: alcohol, stimulants
• Discontinuation of sedative-hypnotics
• Ageing: sleep requirement reduces from ~50 years onwards

Hypersomnia

• Defining feature: daytime sleepiness
• Associated with: depressed patients (especially bipolar with history of mania/hypomania), stimulant withdrawal, excessive sedatives/tranquilisers, medical disorders

• Narcolepsy: Irresistible sleep attacks (10-15 min), sleep-onset REM, often starts in adolescence. Tetrad: sleep attacks + cataplexy (sudden loss of muscle tone triggered by emotion) + hypnagogic hallucinations + sleep paralysis
• Kleine-Levin syndrome: Relapsing-remitting episodes - hypersomnia + cognitive impairment + apathy + derealization + psychiatric/behavioural disturbances. Boys > girls. >50% have hyperphagia, hypersexuality, or depressed mood. Brief visual hallucinations (snakes near bed). Triggered by infection, relapses every 1-12 months, median 14 years. Hypoactivity in thalamic, hypothalamic, frontal, temporal regions
• Pickwickian / Obstructive Sleep Apnoea: Obesity + cyanosis + apnoeic phases up to 1 min + daytime somnolence. Typically middle-aged, severe snoring (reported by bed partner). Associated daytime fatigue
• Psychogenic hypersomnia: Dissociative stupor, conversion symptoms; neurotic patients may complain of daytime somnolence and inability to concentrate

Parasomnias

• Sleepwalking (somnambulism): Arises during slow-wave sleep (stages 3-4), first third of night. More in children, males. Aimless purposeless wandering, monosyllabic replies, little environmental awareness, rarely injurious. Family history common. Associated with enuresis. Can be precipitated by some psychotropic medications
• Night terrors (sleep terror disorder): Deep sleep, early night. Intense anxiety, shouting, rapid pulse/respiration. Complete amnesia on waking. Different from nightmares - nightmares are REM-based dreams remembered vividly
• Nightmares: REM sleep (paradoxical sleep). Occur in PTSD (re-experiencing traumatic content), depression, anxiety disorders, occasionally in healthy individuals. Vivid dreams/nightmares can be a medication side effect (e.g. beta-blockers, SSRIs)
• Sexsomnia: Sexual behaviour during sleep; occurs in NREM parasomnias (confusional arousal, sleep terror, sleepwalking), REM sleep behaviour disorder, partial complex seizures, OSA
• Restless legs syndrome / Nocturnal myoclonus: Sensory symptoms (peculiar leg sensations with irresistible need to move); repetitive myoclonic jerking waking both patient and partner

Dreams as Symptoms

• To be considered a symptom, a dream must acquire unpleasant affect
• Recurring nightmares with anxiety, terror, or foreboding indicate a prevailing affect
• Re-experiencing of traumatic content in dreams is a diagnostic feature of PTSD
• Dream images in disturbed sleep: more vivid than fantasy, but distinct from hallucinations or delusions

Key Interaction Pairs

What Does Family Dynamics Mean?

• "There is a large amount of empirical literature showing that family dynamics and the degree of a supportive family environment affect mental and physical health, including symptom severity, treatment response, and recovery."
• A negative, high-expressed-emotion (high-EE) family environment is associated with higher relapse rates in schizophrenia, bipolar disorder, and depression
• A supportive family environment is associated with lower prevalence of hypertension, cardiovascular disease, dementia, depression, anxiety, and substance use disorders
• In cancer and other life-threatening illness, the medical staff invades the family system to create an ad hoc hybrid system - the milieu within which psychiatric consultation requests are generated

• Communication patterns (open vs. secretive, hostile vs. warm)
• Role boundaries (enmeshment vs. rigid disengagement)
• Expressed emotion (criticism, hostility, over-involvement)
• History of family mental illness and its impact on the patient's upbringing
• Who provides support? Who is a stressor?
• Impact of patient's illness on family members

Significance of Knowing Pathways of Care

1. Diagnostic efficiency: A defined pathway means the right assessments happen in the right order at the right time - reducing delays to diagnosis (e.g., a first-episode psychosis pathway ensures rapid access to an Early Intervention Service)
2. Treatment quality and safety: Pathways encode evidence-based standards. They reduce variability in care and prevent omissions (e.g., suicide risk assessment at every contact on a pathway for affective disorders)
3. Multi-agency coordination: Psychiatric care often involves primary care, community mental health teams, inpatient units, social services, housing. Knowing the pathway helps you understand who is responsible for what at each stage
4. Patient communication and consent: Explaining the pathway to the patient reduces anxiety, improves engagement, and supports informed consent - the patient knows what to expect next
5. Audit and accountability: Pathways create measurable standards that can be audited - e.g., time from referral to first assessment, length of stay, re-admission rates
6. Resource allocation: Where geriatricians or specialists are scarce (e.g., fragility fracture networks), innovative pathway design distributes care efficiently
7. Medico-legal relevance: Deviation from an agreed pathway is auditable evidence. Documenting why you deviated protects you professionally

1. SLEEP — ELABORATION POINTS

Why Sleep Matters in Psychiatry

ICSD Categories of Sleep Disorders

1. Insomnias
2. Sleep-related breathing disorders
3. Hypersomnias not due to a breathing disorder
4. Parasomnias
5. Sleep-related movement disorders
6. Other sleep disorders
7. Isolated symptoms / apparently normal variants

Insomnia

• Early insomnia (initial) — Difficulty falling asleep; mind dwelling on affect-laden experiences, rehearsing problems → Anxiety disorders, arousal states
• Middle insomnia — Frequent awakenings; less deep sleep; sensitive to unfamiliar surroundings → Anxiety / neurotic disorders
• Late insomnia (terminal) — Early-morning awakening; inability to return to sleep; marked diurnality of mood — worst despondency in the morning → Depressive phase of affective disorders
• Reduced sleep requirement — Markedly reduced need for sleep; patient often does NOT complain → Mania / hypomania

Hypersomnia

Parasomnias

Dreams as Symptoms

• To qualify as a symptom, a dream must acquire unpleasant affect.
• Recurring nightmares with anxiety, terror, or foreboding indicate a prevailing affect.
• Re-experiencing of traumatic content in dreams = diagnostic feature of PTSD.
• Vivid, intense dreams: common SSRI side effect (vivid with strong colours/clarity — not true nightmares).
• Hypnagogic hallucinations: vivid hallucinations at sleep onset (narcolepsy, severe insomnia).
• Hypnopompic hallucinations: occur on waking from sleep.
• Sleep drunkenness (confusional arousal): slowed speech, disorientation, prolonged confusion on waking from NREM sleep; patient may sleep 17+ hours.

2. APPETITE — ELABORATION POINTS

• Direction of change — increased or decreased?
• Onset and timeline — sudden vs. gradual?
• Associated behaviours — restriction, purging, bingeing?
• Weight trajectory — how much change over what period?
• Relation to mood episodes?
• Any change in taste or smell sensation?

3. COMMON PRESCRIBED DRUGS CAUSING PSYCHIATRIC SYNDROMES

Drug-Induced Depression

• Antihypertensives: methyldopa, reserpine, beta-blockers (propranolol), clonidine

• Stimulants: ephedrine, pseudoephedrine
• Isotretinoin (acne treatment)

4. PHYSICAL ILLNESS DRUGS INTERACTING WITH PSYCHOTROPICS

• Warfarin + SSRIs/carbamazepine: SSRIs increase bleeding risk; carbamazepine (CYP inducer) reduces INR; fluvoxamine raises warfarin levels (CYP2C9 inhibition)
• ACE inhibitors + Lithium: reduce renal lithium clearance — lithium toxicity risk
• Thiazide diuretics + Lithium: significantly raise lithium levels — dangerous combination
• NSAIDs + Lithium: reduce renal lithium clearance — toxicity risk
• Macrolide antibiotics + Clozapine/quetiapine: CYP3A4 inhibition — raised psychotropic levels
• Rifampicin + Clozapine/olanzapine/haloperidol: CYP1A2/3A4 induction — dramatically reduces psychotropic levels
• Ciprofloxacin/Enoxacin + Clozapine/olanzapine: CYP1A2 inhibition — raised levels, toxicity risk
• Carbamazepine + Oral contraceptives/haloperidol/olanzapine/risperidone/quetiapine: enzyme induction — reduced levels; contraceptive failure
• Omeprazole (PPI) + Clozapine: CYP1A2 inhibition — raises clozapine levels
• Adrenaline (epinephrine) + TCAs: TCAs block reuptake — exaggerated cardiovascular response
• Class I antiarrhythmics (quinidine) + TCAs/haloperidol: additive QTc prolongation
• Tramadol/fentanyl + MAOIs/SSRIs: serotonin syndrome
• Linezolid (antibiotic) + SSRIs/MAOIs: linezolid is a weak MAOI — serotonin syndrome
• Tobacco smoke + Clozapine/olanzapine: CYP1A2 induction (hydrocarbons) — reduces plasma levels; stopping smoking raises levels significantly

5. WHAT DOES FAMILY DYNAMICS MEAN?

Why It Matters Clinically

• High Expressed Emotion (high-EE) — criticism, hostility, over-involvement — is associated with higher relapse rates in schizophrenia, bipolar disorder, and depression.
• Supportive family environment is associated with lower prevalence of hypertension, cardiovascular disease, dementia, depression, anxiety, and substance use disorders.
• In life-threatening illness (e.g. cancer), medical staff invades the family system, creating a hybrid system within which psychiatric consultation requests are generated.
• Family dynamics are relevant to child/adolescent psychiatry — trauma and dysfunction can lead to poverty, addiction, or chronic mental illness decades later.

What to Assess in History

• Communication patterns: open vs. secretive? Hostile vs. warm?
• Role boundaries: enmeshment vs. rigid disengagement?
• Expressed Emotion (EE): criticism, hostility, over-involvement from family members?
• Family psychiatric history: mental illness in parents/siblings and its impact on upbringing?
• Support vs. stressor: who provides support? Who is a stressor?
• Impact of illness: how has the patient's illness affected family members?

• Psychiatrists (consultant + trainees)
• Community Psychiatric Nurses (CPNs)
• Social workers
• Occupational therapists
• Psychologists
• Support workers / care coordinators

• Assess and manage patients with moderate-to-severe mental illness (schizophrenia, bipolar, severe depression, personality disorders)
• Coordinate care between GP (primary care), inpatient units, housing, social services
• Prescribe and monitor medication in the community
• Provide psychological therapies and psychosocial interventions
• Act as the gatekeeper to inpatient admission and to specialist services (e.g. Early Intervention in Psychosis, Crisis teams)

Role Boundaries in Families

Enmeshment (Boundaries too loose)

• Parents make decisions for adult children
• Family members speak for each other ("we feel...")
• Over-involvement — a parent attends every appointment, answers every question on the patient's behalf
• No privacy; everyone knows everyone's business
• Strong loyalty demands — guilt when trying to be independent
• Distress in one member immediately destabilises the whole family

• Linked to high Expressed Emotion (over-involvement subtype)
• Associated with poor recovery in schizophrenia and eating disorders
• Common pattern in families of patients with anorexia nervosa

Rigid Disengagement (Boundaries too rigid/strict)

• Members do not communicate openly
• Emotional needs go unacknowledged
• "Mind your own business" culture
• No support offered during crisis
• Members live parallel lives under the same roof

• Associated with neglect, emotional unavailability
• Linked to insecure attachment and later personality difficulties
• Increases vulnerability to depression, substance use, and self-harm

• Family dynamics are relevant to child/adolescent psychiatry - trauma and dysfunction can lead to poverty, addiction, or chronic mental illness decades later.

• Communication patterns: open vs. secretive? Hostile vs. warm?
• Role boundaries (see below): enmeshment vs. rigid disengagement?
• Expressed Emotion (EE): criticism, hostility, over-involvement from family members?
• Family psychiatric history: mental illness in parents/siblings and its impact on upbringing?
• Support vs. stressor: who provides support? Who is a stressor?
• Impact of illness: how has the patient's illness affected family members?

• Parents make decisions for adult children
• Family members speak for each other ("we feel...")
• Over-involvement - a parent attends every appointment, answers every question on the patient's behalf
• No privacy; everyone knows everyone's business
• Strong loyalty demands - guilt when trying to be independent
• Distress in one member immediately destabilises the whole family Clinical example: A 28-year-old with anxiety whose mother still manages all his appointments, speaks during his consultations, and becomes upset if he tries to live independently. Psychiatric relevance: linked to high Expressed Emotion (over-involvement subtype); associated with poor recovery in schizophrenia and eating disorders; common in families of patients with anorexia nervosa.

• Members do not communicate openly
• Emotional needs go unacknowledged
• "Mind your own business" culture within the family
• No support offered during crisis
• Members live parallel lives under the same roof Clinical example: A depressed teenager whose parents are unaware of her distress because "we don't talk about feelings in this family." Psychiatric relevance: associated with neglect, emotional unavailability; linked to insecure attachment and later personality difficulties; increases vulnerability to depression, substance use, and self-harm.

1. WHEN DID THE SLEEP PROBLEM START? WAS IT SUDDEN OR GRADUAL?

1. HOW LONG DOES IT TAKE YOU TO FALL ASLEEP?

1. DO YOU WAKE DURING THE NIGHT? HOW MANY TIMES? WHAT WAKES YOU?

• If they wake breathless, gasping, or their partner reports snoring and stopping breathing - this points to obstructive sleep apnoea. Ask about obesity, loud snoring, daytime fatigue, and morning headaches.
• If they wake with intense fear, shouting, rapid heartbeat, and have no memory of it in the morning - this is a night terror (NREM sleep, deep slow-wave sleep, early in the night). Complete amnesia is the distinguishing feature. The patient will not be able to tell you what frightened them. This is different from a nightmare.
• If they wake with a vividly remembered frightening dream - this is a nightmare (REM sleep). The patient can describe what happened in the dream. This is common in PTSD (where re-experiencing traumatic content in dreams is a diagnostic feature), depression, and anxiety.
• If they wake needing the toilet, in pain, or because of a partner's movements - this may be a medical cause and should prompt a physical review.
• If they wake for no apparent reason but cannot return to sleep, with an associated low mood - this begins to overlap with early morning awakening (see below).

1. DO YOU WAKE UP EARLIER THAN YOU INTEND TO AND CANNOT GET BACK TO SLEEP?

1. HOW MUCH TOTAL SLEEP DO YOU GET? HAS THIS CHANGED?

• Depression with atypical features or bipolar depression (especially in patients with a history of mania or hypomania)
• Stimulant withdrawal
• Excessive use of sedatives or tranquilisers
• Narcolepsy
• Obstructive sleep apnoea
• Kleine-Levin syndrome

1. DOES YOUR SLEEP FEEL REFRESHING?

1. DO YOU FEEL EXCESSIVELY SLEEPY DURING THE DAY? HAVE YOU FALLEN ASLEEP INAPPROPRIATELY?

• Narcolepsy: sudden attacks of irresistible sleepiness (10-15 minutes), sleep-onset REM, often starting in adolescence. Ask specifically about cataplexy - sudden episodes of muscle weakness or collapse triggered by strong emotion (laughing, surprise, orgasm). This is almost pathognomonic of narcolepsy. Also ask about hypnagogic hallucinations (vivid hallucinations while falling asleep) and sleep paralysis (waking and being unable to move, which can be very frightening).
• Obstructive sleep apnoea: daytime sleepiness is the main complaint. The patient may have fallen asleep driving or at work. Ask about snoring, witnessed apnoeas, obesity, neck size, hypertension.
• Kleine-Levin syndrome: episodic hypersomnia in adolescents, usually males. During episodes (lasting days to weeks), the patient sleeps excessively and when awake shows hyperphagia (ravenous eating), cognitive impairment, derealization, and sometimes behavioural disturbance, delusions, or hallucinations. Between episodes, they are completely normal. It is rare but important not to miss.

1. DO ANYTHING UNUSUAL HAPPEN WHILE YOU ARE ASLEEP?

1. DO YOU HAVE STRANGE SENSATIONS IN YOUR LEGS AT NIGHT?

1. WHAT MEDICATIONS ARE YOU TAKING? DO YOU USE ALCOHOL, CAFFEINE, OR OTHER SUBSTANCES?

• SSRIs and SNRIs: cause sleep fragmentation, vivid dreams, and nightmares (due to REM suppression followed by REM rebound). A patient starting an SSRI who then reports intense, colourful, vivid dreams is experiencing a well-known side effect, not a new psychiatric symptom.
• Steroids (prednisolone, dexamethasone): cause insomnia and can cause mania and psychosis, particularly if taken in the evening.
• Beta-blockers: cause nightmares (lipid-soluble ones like propranolol cross the blood-brain barrier).
• Theophylline, salbutamol, ephedrine: stimulant effects - cause initial insomnia and palpitations.
• Stimulants (methylphenidate): if dosed too late in the day, cause significant insomnia.
• Levodopa and dopamine agonists: cause vivid dreams, nightmares, and psychosis.
• Sedative-hypnotics: rebound insomnia on discontinuation is severe and must be anticipated.

1. IS THERE ANYTHING THAT MAKES YOUR SLEEP BETTER OR WORSE?

• Do you sleep better or worse in unfamiliar surroundings? (Neurotic patients sleep worse in unfamiliar environments - Jovanovic 1978)
• Do you nap during the day? This is directly relevant because excessive daytime napping fragments nocturnal sleep and is a key perpetuating factor in insomnia.
• What do you do when you cannot sleep? Getting up and doing something vs. lying in bed catastrophising - the latter reinforces conditioned arousal.
• Do you use screens or phones in bed? Blue light suppresses melatonin and delays sleep onset.

1. HAS YOUR APPETITE CHANGED? IN WHICH DIRECTION?

• Depression - loss of appetite is one of the neurovegetative symptoms of a depressive episode. The patient does not feel hungry and has to force themselves to eat, or simply does not eat at all. They may lose significant weight without actively trying to.
• Grief - appetite loss is a normal and expected feature of bereavement, but if it is severe or prolonged it raises the question of a complicated grief reaction or emerging depression.
• Anxiety disorders - chronic anxiety suppresses appetite through sustained activation of the sympathetic nervous system and elevated cortisol.
• Chronic medical illness - malignancy, cardiac failure, renal failure, hepatic disease, and many infections suppress appetite in their later stages.

• Atypical depression - in contrast to melancholic depression, atypical depression is characterised by increased appetite (often with carbohydrate craving), hypersomnia, leaden paralysis, and mood reactivity. This distinction is clinically important because atypical depression responds better to MAOIs and SSRIs than to TCAs.
• Bipolar depression - hypersomnia and hyperphagia are common features of the depressive phase of bipolar disorder.
• Mania - some patients in hypomanic or manic states have increased appetite alongside their increased energy.
• Psychotropic medication side effects - atypical antipsychotics (olanzapine, clozapine, quetiapine, risperidone) cause marked appetite increase, particularly for sweets and fatty foods. This is one of the most clinically significant causes of weight gain in psychiatric patients.

1. HOW HAS YOUR WEIGHT CHANGED? HOW MUCH, AND OVER WHAT PERIOD?

1. HOW DO YOU FEEL ABOUT YOUR WEIGHT AND BODY SHAPE?

1. Restriction of calorie intake resulting in significantly low body weight
2. Intense fear of gaining weight or becoming fat (or persistent behaviour that interferes with weight gain, even if the fear is not explicitly stated)
3. Disturbance in the way body weight or shape is experienced - typically the patient believes their body is too large despite being objectively severely underweight

1. WHAT DO YOU EAT IN A TYPICAL DAY? WALK ME THROUGH YESTERDAY.

• Total caloric intake - is it severely restricted?
• Food rituals - eating only at certain times, only certain portions, cutting food into tiny pieces, eating in a specific order, avoiding whole food groups
• Rules - "I don't eat after 6pm," "I only eat if I exercised first," "I allow myself 800 calories maximum"
• Avoidances - specific foods labelled as "bad," "unsafe," or "fattening"
• Compulsive exercise following eating

1. DO YOU EVER HAVE EPISODES WHERE YOU EAT MUCH MORE THAN YOU INTENDED TO?

1. Consuming an objectively large amount of food - more than most people would eat in similar circumstances
2. A sense of loss of control - feeling unable to stop, feeling driven to continue

• What foods did you eat? (typically high-calorie, high-carbohydrate - ice cream, crisps, bread, chocolate, biscuits)
• How much - can they estimate? (can be thousands of calories in one sitting)
• How long did it last?
• Were you alone? (bingeing is almost always done in secret due to shame)
• What were you feeling before it started? (usually tension, anxiety, low mood, or a perceived dietary transgression - "I already ruined today so I may as well...")
• What were you feeling during it? (a brief sense of numbness or relief, then loss of control)
• What were you feeling after? (shame, disgust, guilt - which then drives compensatory behaviour or worsens low mood)

1. AFTER EATING, DO YOU EVER TRY TO COMPENSATE - MAKE YOURSELF SICK, USE LAXATIVES, EXERCISE EXCESSIVELY?

• Self-induced vomiting: the most common. Ask gently and directly. Signs on examination include Russell's sign (calluses on the dorsum of the knuckles from teeth scraping), dental enamel erosion, parotid gland enlargement, and hypokalaemia (electrolyte abnormality from vomiting - can cause cardiac arrhythmias).
• Laxative misuse: the patient may use large quantities. Causes hypokalaemia, hyponatraemia, and gastrointestinal complications.
• Diuretic misuse.
• Fasting: compensating for a binge by eating nothing the next day. This perpetuates the restrict-binge cycle.
• Excessive exercise: driven and compulsive - exercising even when injured or unwell, significant distress if prevented from exercising, exercise that is punitive rather than pleasurable.

1. WHAT IS YOUR RELATIONSHIP WITH FOOD LIKE - HAS IT ALWAYS BEEN THIS WAY?

1. ARE YOU ON ANY MEDICATIONS? HAVE ANY NEW MEDICATIONS BEEN STARTED RECENTLY?

• Atypical antipsychotics: olanzapine and clozapine cause the most weight gain. Quetiapine and risperidone are also significant. Aripiprazole and ziprasidone are more weight-neutral. Kaplan and Sadock describe a case of a patient with schizoaffective disorder who gained 40 lb in several months after being switched to an atypical antipsychotic, with a marked hunger specifically for sweets and fatty foods.
• Mood stabilisers: lithium and valproate both cause weight gain and increased appetite.
• Antidepressants: mirtazapine causes significant appetite increase and weight gain (due to histamine H1 antagonism). TCAs (especially amitriptyline) similarly. SSRIs can cause initial appetite suppression but weight gain with long-term use.

• Stimulants: methylphenidate and amphetamine-based ADHD medications suppress appetite, particularly at peak effect. This is clinically significant in children on stimulants - monitor height and weight.
• SSRIs and SNRIs: commonly cause initial appetite suppression and nausea, which usually resolves but can cause weight loss in the short term.
• Topiramate and bupropion: associated with weight loss.
• Metformin: reduces appetite.

• Lithium, SSRIs, opioids, antibiotics

1. HOW DOES EATING MAKE YOU FEEL? BEFORE, DURING, AND AFTER?

1. MEDICAL HISTORY - ANY PHYSICAL CAUSES RULED OUT?

• Malignancy (any organ system - this is the one not to miss)
• Hyperthyroidism - weight loss despite increased appetite; also causes anxiety, palpitations, tremor
• Addison's disease - anorexia, weight loss, fatigue, hyperpigmentation, hyponatraemia
• Inflammatory bowel disease (Crohn's, ulcerative colitis)
• Malabsorption (coeliac disease, chronic pancreatitis)
• HIV/AIDS
• Chronic infections (tuberculosis)
• Cardiac failure, chronic renal failure, chronic liver disease

• Hypothyroidism - weight gain, fatigue, cold intolerance, constipation
• Cushing's syndrome - central obesity, moon face, striae, hypertension, glucose intolerance
• Insulinoma - episodic hypoglycaemia driving hunger and eating
• Polycystic ovary syndrome (PCOS)

2. Pathways of care (with clinical significance elaborated in the same detail)

1. SLEEP - CLINICAL HISTORY AND ELABORATION

• Breathless, gasping, partner reports snoring and apnoeas - obstructive sleep apnoea
• Wakes with intense fear, screaming, rapid pulse, complete amnesia next morning - night terror (NREM, deep sleep, early night). Cannot describe what frightened them.
• Wakes from a vividly remembered frightening dream - nightmare (REM sleep, later in night). Can describe it. Common in PTSD (re-experiencing is a diagnostic criterion), depression, anxiety, and as a medication side effect (beta-blockers, SSRIs).
• Wakes for no clear reason, cannot return to sleep, low mood - overlaps with terminal insomnia.

• Narcolepsy: irresistible sleep attacks (10-15 min). Ask specifically about cataplexy (sudden muscle weakness triggered by strong emotion - laughing, surprise, orgasm - almost pathognomonic of narcolepsy), hypnagogic hallucinations, and sleep paralysis.
• OSA: daytime sleepiness is the main complaint. Ask about snoring, witnessed apnoeas, obesity, hypertension.
• Kleine-Levin syndrome: episodic hypersomnia in adolescent males. During episodes - hypersomnia + hyperphagia + cognitive impairment + derealization + brief visual hallucinations. Between episodes completely normal. Triggered by infection.
• Hypersomnia in depression: especially bipolar depression and atypical depression.

• Sleepwalking: slow-wave NREM sleep, first third of night. Aimless wandering, monosyllabic, no memory. More in children and males. Family history common. Can be triggered by psychotropic medications, particularly sedative-hypnotics.
• REM sleep behaviour disorder: patient acts out dreams - kicks, punches, shouts. Purposive behaviour related to dream content. Associated with neurodegenerative disease (Parkinson's, Lewy body dementia) - can precede the neurological diagnosis by years.
• Night terror vs nightmare: night terror = NREM, early night, complete amnesia, patient cannot describe what frightened them. Nightmare = REM, later in night, vividly remembered, patient can tell you the whole dream. These are commonly confused.

• SSRIs: sleep fragmentation and vivid intense dreams (not nightmares). Patient starting SSRI who reports intense colourful dreams is experiencing a known side effect.
• Steroids: insomnia, mania, psychosis - especially if taken in the evening.
• Beta-blockers: nightmares (lipid-soluble ones like propranolol cross the blood-brain barrier).
• Theophylline, salbutamol, stimulants: initial insomnia.
• Sedative-hypnotics: severe rebound insomnia on discontinuation.
• Alcohol: initially sedating but causes severe sleep fragmentation in the second half of the night as it is metabolised. Patients using alcohol to sleep wake at 3-4am anxious and unrefreshed - trapped in a cycle. Withdrawal causes nightmares and in serious cases delirium tremens.

1. APPETITE - CLINICAL HISTORY AND ELABORATION

1. FAMILY DYNAMICS - CLINICAL HISTORY AND ELABORATION

• Parent still makes decisions for an adult child (what to eat, when to sleep, who to see)
• Family members speak for the patient ("We feel he needs more medication")
• Parent attends and dominates every clinical appointment, preventing the patient from speaking for themselves
• Patient feels intense guilt about any attempt at independence - loyalty demands that cannot be questioned
• Any distress in one member immediately destabilises the whole family unit
• No privacy - the family knows every detail of the patient's inner life and clinical history

• "We don't talk about feelings in our family"
• Patient had difficult experiences (abuse, trauma, mental illness, bereavement) that were never discussed or acknowledged at home
• During a crisis, the patient had no one to turn to within the family
• Emotional needs were consistently unacknowledged in childhood
• "Mind your own business" culture - privacy enforced at the cost of support

• Parental mental illness (depression, alcohol dependency, personality disorder) - children of parents with mental illness are at significantly increased risk of developing mental illness themselves, both through genetic factors and through disrupted attachment and family environment
• Domestic violence - profound impact on attachment, emotional regulation, and stress response systems; increases risk of PTSD, depression, anxiety, and borderline personality disorder
• Bereavement or loss in childhood - parental loss before age 11 is associated with increased vulnerability to depression in adulthood
• Abuse (physical, sexual, emotional) - the most significant environmental risk factor for borderline personality disorder and a major risk factor for all psychiatric illness
• Parental alcohol or substance misuse - associated with parentification (child takes on adult responsibilities), disrupted attachment, and shame-based family dynamics

1. PATHWAYS OF CARE - CLINICAL SIGNIFICANCE AND ELABORATION

1. DIAGNOSTIC EFFICIENCY A defined pathway means the right assessments happen in the right sequence at the right time.

1. TREATMENT QUALITY AND SAFETY - PREVENTING OMISSIONS Pathways encode the evidence base. They act as a checklist ensuring critical steps are not missed through haste, cognitive load, or clinical variation.

• Suicide risk assessment at every contact for patients on an affective disorder pathway - not just at admission and discharge
• Clozapine monitoring protocol for patients on clozapine - mandatory FBC at specified intervals, with defined thresholds for dose reduction or stopping
• Physical health monitoring in patients on antipsychotics - weight, BMI, fasting glucose, HbA1c, lipids, blood pressure at baseline and annually (metabolic syndrome protocol)
• NICE guidelines on lithium monitoring - renal function, thyroid function, serum lithium levels at specified intervals

1. MULTI-AGENCY COORDINATION Psychiatric care involves multiple organisations simultaneously - primary care (GP), Community Mental Health Teams (CMHTs), crisis services, inpatient units, social services, housing, employment support, carer services.

1. PATIENT COMMUNICATION AND INFORMED CONSENT Explaining the pathway to the patient is a clinical intervention in itself.

1. AUDIT AND ACCOUNTABILITY - MEASURABLE STANDARDS Pathways create standards that can be measured, audited, and improved.

• Time from referral to first CMHT assessment (target often 28 days for non-urgent, much less for urgent)
• Time from referral to first EIP appointment (target 2 weeks in UK NHS)
• Waiting times for psychological therapies (IAPT targets: 6 weeks to first appointment, 18 weeks to treatment)
• Re-admission rates within 30 days of discharge (a proxy for inadequate discharge planning)
• Completion rates of physical health monitoring on antipsychotics

1. RESOURCE ALLOCATION Psychiatric services operate under significant resource constraints. Specialist skills (old age psychiatrists, forensic psychiatrists, perinatal psychiatrists, neuropsychiatrists) are scarce. Knowing the pathway prevents misallocation.

1. MEDICO-LEGAL PROTECTION Deviation from an agreed care pathway is auditable. If a patient comes to harm and the pathway was not followed, the clinician must be able to demonstrate either that the pathway was followed, or that there was a documented clinical reason for deviation.

• Referring patients to the right service at the right time (early intervention reduces long-term harm)
• Not missing mandatory monitoring steps (clozapine, lithium, metabolic monitoring)
• Coordinating across agencies so no one falls through the gaps
• Communicating the plan to the patient to improve engagement and consent
• Meeting auditable standards that protect both patient and clinician
• Allocating scarce specialist resources efficiently
• Documenting deviations from the pathway with clear clinical reasoning
