I now have enough content from the Kaplan & Sadock's Synopsis of Psychiatry plus my clinical knowledge to provide a comprehensive, structured answer. Let me synthesize this.
History Taking: 10-Year-Old Female with Gradual Progressive Abnormal Aggressive Behaviour
A 10-year-old girl with gradual, progressive aggression requires a structured, multi-domain psychiatric history. The differential is broad (conduct disorder, ADHD, mood disorder, trauma, organic causes, early-onset psychosis), so the history must systematically cover all possible contributors.
1. Chief Complaint & History of Present Illness (HPI)
- Onset: When exactly did the behaviour start? Was there a triggering event (trauma, loss, school change)?
- Progression: How has it changed over time? Is it getting worse, staying the same, or episodic?
- Nature of aggression:
- Physical (hitting, biting, throwing objects) vs. verbal (threats, screaming)
- Directed at whom? (parents, siblings, peers, strangers, animals)
- Provoked vs. unprovoked?
- Planned/purposeful vs. impulsive/explosive?
- Frequency & severity: How many episodes per week/day? Any injuries caused?
- Setting: At home only, school only, or both?
- Associated features: Lying, stealing, bullying, vandalism, fire-setting, truancy, cruelty to animals (conduct disorder criteria)
2. Psychiatric Review of Symptoms
- Mood: Persistent sadness, irritability, mood swings, euphoria (bipolar)
- Anxiety: Separation anxiety, social anxiety, panic attacks
- Psychotic symptoms: Hallucinations (hearing voices commanding aggression), paranoid ideas, disorganized thinking
- Hyperactivity/inattention: Poor concentration, impulsivity, restlessness (ADHD)
- Obsessions/compulsions
- Self-harm or suicidal ideation
- Sleep disturbances: Nightmares, sleep disruption
3. Developmental History
- Pregnancy & perinatal: Maternal infections, substance use, birth complications, prematurity
- Milestones: Delays in motor, speech/language, social development?
- Social development: Did she make friends normally? Play imaginatively? Show empathy?
- Early temperament: Was she always difficult, irritable, or hard to soothe?
- Prior behavioural problems: Oppositional defiant behaviour from earlier childhood?
4. Past Psychiatric History
- Previous episodes of aggression or behavioural disturbance
- Prior psychiatric diagnoses (ODD, ADHD, ASD, anxiety, depression)
- Previous psychiatric hospitalisations or emergency visits
- Previous psychological assessments or therapy
- Response to past treatments
5. Medical & Neurological History
- Head trauma or TBI — even mild TBI can cause personality/behavioural change
- Seizure disorder — especially temporal lobe epilepsy (inter-ictal aggression)
- Thyroid disease — hyperthyroidism can cause irritability and aggression
- Autoimmune encephalitis (anti-NMDA receptor encephalitis) — can present with behavioural change in children
- CNS infections (meningitis, encephalitis)
- Chromosomal/genetic syndromes (e.g., 22q11 deletion, Prader-Willi, fragile X)
- Metabolic disorders: Wilson's disease, PKU, porphyria
- Medication history: Current and past medications (steroids, stimulants, antiepileptics can affect behaviour)
6. Family History
- Family history of psychiatric disorders: Bipolar disorder, schizophrenia, ADHD, substance use, personality disorders, conduct disorder
- Family history of neurological conditions: Huntington's, epilepsy, neurodegenerative disorders
- Family dynamics: Parental mental illness, domestic violence, parental separation, parenting style
7. Social History & Environment
- Family structure: Who does she live with? Changes in household?
- Parenting: Discipline style, consistency, parent-child relationship quality
- School: Academic performance (any decline?), teacher reports, suspensions/exclusions
- Peer relationships: Social isolation, bullying (as victim or perpetrator)
- Trauma/abuse: Physical, sexual, emotional abuse or neglect (must ask sensitively)
- Adverse childhood experiences (ACEs): Domestic violence, parental substance abuse, incarceration
- Socioeconomic factors: Poverty, housing instability
8. Substance Use History
- Although age 10 is young, ask about:
- Exposure to substances at home
- Any personal experimentation with alcohol, cannabis, inhalants
- Peer substance use
9. Review of Systems (Organic Screening)
- Weight loss or gain (thyroid, malignancy)
- Headaches (raised ICP, tumour)
- Visual or auditory changes
- Involuntary movements (Wilson's disease, Huntington's juvenile form, PANDAS)
- Fever, rash (autoimmune/infectious)
- Urinary symptoms (Wilson's — Kayser-Fleischer rings, liver signs)
10. Collateral History
Because children are often poor historians about their own behavioural problems:
- From parents/caregivers: Full behavioural account, family stressors
- From teachers: Academic functioning, peer interactions, classroom behaviour
- From prior clinicians: Previous assessments, therapy notes
Key Differentials to Guide History
| Diagnosis | Key Historical Features to Elicit |
|---|
| Conduct Disorder | Pattern of violating others' rights, cruelty to animals, fire-setting, persistent lying |
| ODD | Defiant, argumentative, vindictive — but without severe conduct violations |
| ADHD | Impulsive aggression, inattention, hyperactivity from early childhood |
| Bipolar Disorder | Episodic irritability/euphoria, decreased sleep need, grandiosity |
| Early-Onset Psychosis | Hallucinations, paranoia, disorganised thinking |
| PTSD | History of trauma, hypervigilance, nightmares, emotional dysregulation |
| Autism Spectrum Disorder | Social communication deficits, restricted interests, sensory sensitivities |
| Organic cause | Headaches, seizures, movement disorder, systemic symptoms |
The gradual and progressive nature in a young girl is a critical feature — it suggests an evolving pathology (neurodevelopmental, mood disorder, or early-onset psychosis) rather than a purely reactive/environmental cause, and warrants thorough organic work-up alongside psychiatric evaluation.
