Kleptomania and Mutilomania - Rajesh FMT Textbook

Note on spelling: "Multilimania" is actually Mutilomania (from the Rajesh FMT textbook - The Essentials of Forensic Medicine and Toxicology, 36th Edition, 2026). These are both types of Impulse disorders described in the psychiatry chapter.

IMPULSE (Parent Concept)

"Impulse is a sudden and irresistible force compelling a person to the conscious performance of some action without motive or forethought."

• A sane person is capable of controlling an impulse.
• An insane person - having no judgment, no reasoning power, and no capacity to understand the facts - may do things on impulse.
• Impulse disorders are usually seen in: imbecility, dementia, acute mania, and epilepsy.

Types of Impulse (All 6 listed in Rajesh FMT)

1. KLEPTOMANIA - Detailed

• The stolen objects have little or no monetary value to the person - this distinguishes kleptomania from ordinary theft (larceny).
• The act is driven by an irresistible impulse, not by financial need or gain.
• The person may feel tension before committing the act and relief/pleasure after it.
• It is classified as a psychiatric disorder (impulse control disorder), not willful criminal behavior.
• In forensic medicine, kleptomania is relevant as a defense in theft/shoplifting cases - the accused may claim reduced or absent criminal responsibility.
• However, the textbook notes: "A sane person is capable of controlling an impulse" - so the defense requires proof of an underlying psychiatric condition.
• It is most commonly seen in association with imbecility, dementia, and epilepsy.

• In ordinary theft: deliberate intent, objects have value, personal gain is the motive.
• In kleptomania: no real motive, objects of little value, driven purely by irresistible impulse, often associated with mental illness.

2. MUTILOMANIA - Detailed

• This is an impulse directed toward animals - the person feels a compulsive, uncontrollable urge to harm or mutilate animals.
• Like all impulse disorders, it arises without prior planning or motive.
• It is associated with the same underlying psychiatric conditions: imbecility, dementia, acute mania, epilepsy.
• In forensic contexts, mutilomania may be raised in cases involving animal cruelty or mutilation, as evidence of an underlying mental disorder.

Context - Adjacent Psychiatric Concepts (Rajesh FMT, same chapter)

• Obsession: A single idea/thought constantly entertained by a person who recognizes it as irrational but cannot resist it (borderline between sanity and insanity). Differs from impulse - in obsession, the person recognizes the irrationality; in impulse, the act is performed without forethought.
• Illusion: False interpretation of a real external stimulus (organic psychoses).
• Hallucination: Perception without any object (seen in fevers, intoxications, insanity).

Drug Dependence and Drug Tolerance

The Essentials of Forensic Medicine and Toxicology, 36th Edition (2026) - K.S. Narayan Reddy (Rajesh FMT)

DRUG DEPENDENCE

Definition

"Drug addicts have a wide range of personalities. Most of them are emotionally unstable, immature, impulsive, angry with society, and unable to achieve their goals or face difficult situations in life. About 10% suffer from psychopathic personality disorders."

Types of Dependence

1. Physical Dependence

• The body adapts physiologically to the presence of the drug.
• On withdrawal, the body reacts with a withdrawal syndrome (abstinence syndrome).
• Seen with: opioids, alcohol (Gamma/Delta alcoholism), barbiturates, benzodiazepines.
• Example - Barbiturate abstinence syndrome: visual disturbance, anxiety, dizziness, insomnia, nausea, vomiting.
• Example - Alcohol: physical dependence with inability to control drinking (Gamma alcoholism) or inability to abstain (Delta alcoholism).

2. Psychological Dependence (Psychic Dependence)

• The person has a compulsive craving for the drug's pleasurable or mood-altering effects.
• No major physical withdrawal, but strong mental craving on abstinence.
• Seen prominently with: cocaine, cannabis, amphetamines.
• Example - Cocaine: initial euphoria and CNS stimulation prompt the user to consume frequently, leading to tolerance and a vicious cycle of physical dependence.

Personality Profile of Drug Dependents

• Emotionally unstable and immature
• Impulsive, with anger toward society
• Unable to achieve goals or handle difficult situations
• ~10% have psychopathic personality disorder
• Liable to antisocial behavior, sexual perversions, and crimes

Drug Dependence in Different Substances (Rajesh FMT)

Alcohol Dependence - Types (Jellinek's Classification):

Opioid Dependence (Morphine/Heroin):

• Morphine is said to be aphrodisiac - hence addiction is commonly seen in adolescents and adults.
• Signs of chronic opioid dependence:
  1. Restlessness, irritability, emaciation, disturbed sleep
  2. Contracted pupil, sluggishly reactive
  3. Marked constipation, nausea, anorexia
  4. Decreased immune response (decreased immune cell counts, macrophage proliferation)
  5. CNS: dementia, mania, intellectual and moral deterioration
  6. Memory loss, neurasthenia
  7. Impotence (temporary type)
  8. Pigmentation around mouth and nostrils

Barbiturate Dependence:

• Signs: ataxia, cerebral dysfunction, dysarthria, hypertonia, parkinsonian tremors
• Social deterioration: mood, behavior, and intellectual dysfunction
• Abstinence causes withdrawal syndrome: anxiety, visual disturbance, dizziness, insomnia, nausea, vomiting

Cannabis Dependence:

• Highest tolerance develops to physical effects; less tolerance to mood and behavioral changes
• Heavy users develop manic, schizophreniform, or confusional psychosis
• Cyclical hyperemesis (every few weeks to months)
• Apathy, poor concentration, social withdrawal, lack of motivation
• Medical complications: chronic infective lung diseases, malignancies, cancer of mouth and larynx

Cocaine Dependence:

• Initial euphoria prompts repeated use → tolerance develops → dose increases → physical dependence becomes a "vicious cycle"
• Sociological complications: violation of legal statutes
• Cocaine withdrawal signs appear on cessation

Amphetamine Dependence:

• As tolerance increases, the dose goes on increasing to reduce depression and prevent lethargy
• High-dose IV abusers: progress from cannabis to IV amphetamine use for intense euphoria

Medico-Legal Importance of Drug Dependence

1. Drug dependence is a recognized cause of insanity - listed alongside cerebral vascular accidents, head injuries, organic diseases.
2. Opioids: death is painless - hence considered an ideal suicidal poison.
3. Euthanasia: morphine is the most commonly used agent.
4. Homicide by opioids: uncommon (bitter taste).
5. Drug addicts are prone to antisocial acts, theft, sexual offenses, and crimes.
6. Engine drivers, pilots, ship officers with drug addiction pose a public safety risk - doctors have a duty to advise regarding change of occupation (privileged communication exception).

DRUG TOLERANCE

Definition

"Tolerance is the ability of an organism to show less response to a specific dose of a chemical than it showed on a previous occasion from the same dose. It results from a decreased reaction between the chemical and the biologic effector substance."

Key Features of Drug Tolerance

Drugs Showing Tolerance (Rajesh FMT)

Alcohol Tolerance - Specific Mechanism

"The signs experienced by the alcohol consumer in previous session are better than this session; to have effect equal to previous session one has to increase the dose. Tolerance keeps on increasing until the consumer's liver gets damaged to the extent that it cannot metabolize alcohol as before - due to this, alcohol stays in body in higher concentration."

• Metabolic tolerance depends on enhanced elimination by ADH or CYP2E1 system.
• Other markers of alcohol abuse: elevated AST, ALT, or AST/ALT ratio.

Tolerance vs. Habituation (Habit)

• Habit/Habituation: The effect of certain poisons decreases with repeated use.
• Tolerance is the measurable, scientific expression of this habit - a less-than-expected response to a fixed dose.
• Tolerance is more a feature of natural substances (opium, cocaine, morphine, tobacco, alcohol) than of synthetic drugs (barbiturates, chloral).

Tolerance for Mineral Substances

• Generally limited compared to organic compounds.
• Arsenic is the exception - arsenophagists (arsenic eaters) can acquire tolerance up to 0.3 g or more in one dose.

Synergism (Related Concept)

"Barbiturates and Alcohol have almost similar effects; one increases the other's effects."
