Substance Use Disorders Practice Questions

Q: Delusion of persecution and formication occur together in

Cocaine. ***Cocaine*** - **Chronic cocaine abuse** can lead to **paranoid delusions** (delusions of persecution) and tactile hallucinations such as **formication** (sensation of insects crawling under the skin, called "**cocaine bugs**"). - These symptoms occur together in **cocaine-induced psychosis**, which can mimic **paranoid schizophrenia**. - The combination of **paranoid delusions with formication** is a classical presentation of **stimulant psychosis**, seen with cocaine. *Amphetamine* - **Amphetamine/methamphetamine abuse** can also cause **psychotic symptoms** including paranoia, delusions of persecution, and formication ("**meth mites**"). - While both cocaine and amphetamine can cause this combination, **cocaine** is the **traditional answer** in medical examinations for this specific combination of symptoms. - Clinically, amphetamine-induced formication is increasingly recognized. *LSD* - **Lysergic acid diethylamide (LSD)** primarily causes **visual hallucinations**, altered perceptions, and synesthesia. - While LSD can induce paranoia and anxiety, **delusions of persecution** and **formication** are not typical features. - LSD effects are more perceptual distortions than true psychotic symptoms. *Cannabis* - **Cannabis use** can sometimes induce **acute psychotic episodes** in vulnerable individuals, particularly with high-potency preparations. - Cannabis effects include **anxiety**, **paranoia**, and **depersonalization**. - **Formication** and prominent **delusions of persecution** are not characteristic of cannabis intoxication.

Q: Dipsomania is usually used in context of:

Alcohol. ***Alcohol*** - **Dipsomania** is a historical psychiatric term used to describe an insatiable, **periodic craving for alcohol** - It refers specifically to episodes of **compulsive alcohol consumption**, distinct from continuous heavy drinking - The term originates from Greek: "dipsa" (thirst) + "mania" (madness) *Any of the above* - The term **dipsomania** is not broadly applicable to any substance or beverage - Its historical and clinical usage is **specifically tied to excessive alcohol intake** - This is not a general term for any form of substance craving *Tonics* - **Dipsomania** does not refer to a craving for tonics, which are typically medicinal or health-promoting beverages - The context of tonics does not involve the compulsive and harmful patterns associated with dipsomania - No psychiatric literature supports this association *Liquids* - While alcohol is a liquid, **dipsomania** is not a general term for craving any liquid - It denotes a **specific pathological craving for an intoxicating substance** (alcohol), not simple hydration - The term refers to the alcoholic content, not the liquid form

Q: The term 'cocaine bugs' refers to:

Ekbom's syndrome. ***Ekbom's syndrome*** - The term **"cocaine bugs"** refers to **formication** - tactile hallucinations of insects crawling on or under the skin, commonly experienced during cocaine intoxication or withdrawal. - While formication itself is a **hallucination** (false sensory perception), chronic cocaine users may develop **Ekbom's syndrome (delusional parasitosis)** - a fixed false belief of being infested by parasites. - Among the given options, Ekbom's syndrome is the most closely associated with the phenomenon of "cocaine bugs," though technically the term specifically describes the tactile hallucinations rather than the delusional disorder itself. *Othello syndrome* - This is a form of **delusional jealousy**, where an individual falsely believes their partner is unfaithful without any real evidence. - It is not associated with tactile hallucinations or the sensation of insects crawling on the skin. *Cotard's syndrome* - This is a rare mental disorder in which a person holds the **nihilistic delusion** that they are dead, do not exist, are putrefying, or have lost their blood or internal organs. - It is distinct from the tactile hallucinations or parasitosis delusions described as "cocaine bugs." *De Clérambault syndrome* - Also known as **erotomania**, this is a delusion in which an individual believes that another person, usually of higher social status, is in love with them. - This condition does not involve tactile hallucinations or the sensation of parasitic infestation.

Q: In chronic alcoholism and its complications, which of the following is seen?

All of the options. ***All of the options*** - **Wernicke's syndrome**, **Delirium tremens**, and **Korsakoff psychosis** are all well-recognized neurological and psychiatric complications associated with **chronic alcoholism** - Chronic alcohol abuse leads to nutritional deficiencies (especially **thiamine deficiency**) and neurotoxicity, predisposing individuals to these distinct but related conditions *Wernicke's syndrome* - Acute neurological disorder caused by **thiamine deficiency** - Characterized by classic triad: **ataxia**, **ophthalmoplegia**, and **confusion** - If untreated, can progress to **Korsakoff psychosis** *Delirium tremens* - Severe form of **alcohol withdrawal** in individuals with long history of heavy drinking - Symptoms include **delirium**, **severe agitation**, **tremors**, **hallucinations**, and autonomic hyperactivity (**tachycardia**, **hypertension**, **fever**) - Medical emergency requiring prompt treatment *Korsakoff psychosis* - Occurs due to chronic **thiamine deficiency**, often following Wernicke's encephalopathy - Characterized by severe **anterograde and retrograde amnesia**, **confabulation**, and relative preservation of other cognitive functions - Often results in permanent cognitive impairment

Q: The following is a feature of Korsakoff's psychosis:-

Confabulation. ***Confabulation*** - **Confabulation**, or the fabrication of vivid but false memories, is a classic symptom of Korsakoff's psychosis, often used to fill gaps in memory. - This symptom arises from significant **anterograde and retrograde amnesia**, particularly for recent events. *Hallucination* - While hallucinations can occur in various neurological and psychiatric conditions, they are **not a primary or defining feature** of Korsakoff's psychosis. - Korsakoff's primarily involves memory impairment, not perceptual disturbances. *Encephalopathy* - **Encephalopathy** (Wernicke's encephalopathy) is the acute precursor to Korsakoff's psychosis, but not a feature of Korsakoff's itself. - Wernicke's encephalopathy is characterized by **acute confusion, ataxia, and ophthalmoplegia**, often resolving or progressing to Korsakoff's if untreated. *Ophthalmoplegia* - **Ophthalmoplegia** (paralysis or weakness of eye muscles) is a key symptom of **Wernicke's encephalopathy**, the acute phase of thiamine deficiency. - While Wernicke's can progress to Korsakoff's, ophthalmoplegia is generally **not a persistent feature** of chronic Korsakoff's psychosis.

Q: The most widely used substance causing dependence worldwide is:

Alcohol. ***Alcohol*** - **Alcohol** is the most widely consumed psychoactive substance globally, leading to a significant burden of dependence and related health issues. - Its widespread availability, social acceptance, and addictive properties contribute to its high rates of dependence across diverse populations. *Cocaine* - While **cocaine** is a powerful and highly addictive stimulant, its use and dependence are not as prevalent globally as alcohol. - The geographical distribution and historical context of cocaine use are more concentrated compared to the ubiquitous nature of alcohol consumption. *Cannabis* - **Cannabis** is one of the most commonly used illicit drugs worldwide, and it can cause dependence, but its overall prevalence of dependence is lower than that of alcohol. - The perception of lower harm and increased legalization in some regions have led to higher rates of use, but alcohol still surpasses it in terms of global dependence rates. *Amphetamines* - **Amphetamines**, including methamphetamine, are potent stimulants known for their high potential for dependence. - However, their global usage and rates of dependence, while significant in certain regions, do not reach the broad societal impact and prevalence seen with alcohol.

Q: Delirium tremens is most commonly seen in:

Alcohol withdrawal. ***Alcohol withdrawal*** - **Delirium tremens (DTs)** is the most severe form of **alcohol withdrawal syndrome**, characterized by **severe disorientation**, **agitation**, and **autonomic instability**. - It typically manifests 2-5 days after the cessation or significant reduction of alcohol intake in individuals with chronic alcohol dependence. *Opioid withdrawal* - Opioid withdrawal symptoms include **dysphoria**, **nausea**, **vomiting**, **diarrhea**, **muscle aches**, **lacrimation**, and **rhinorrhea**. - It does not typically involve the profound **delirium**, **hallucinations**, and **autonomic hyperactivity** seen in DTs. *Opioid intoxication* - Opioid intoxication presents with **central nervous system depression**, including **respiratory depression**, **miosis**, and **decreased level of consciousness**. - These symptoms are opposite to the hyperactive and agitated state characteristic of delirium tremens. *Alcohol intoxication* - Alcohol intoxication causes **central nervous system depression**, leading to **sedation**, **impaired coordination**, and **decreased judgment**. - This is a state of acute impairment from alcohol, not a withdrawal syndrome, and thus presents very differently from delirium tremens.

Q: Which of the following dependence-causing drugs is most commonly abused worldwide?

Cannabis. ***Cannabis*** - **Cannabis** is the most widely cultivated and consumed illicit drug globally, with the highest prevalence of past-year use. - Its widespread availability, relatively lower perception of harm compared to other drugs, and varied forms of consumption (smoking, edibles) contribute to its extensive abuse. *Heroin* - **Heroin** is a highly addictive opioid that causes severe physical dependence and withdrawal symptoms, but its global prevalence is significantly lower than that of cannabis. - Its high cost, illicit nature, and significant health risks, including overdose, limit its abuse to a smaller, though critically affected, population. *Amphetamine* - **Amphetamines**, including methamphetamine, are potent central nervous system stimulants with a significant abuse potential, leading to psycho-behavioral and physical dependence. - While prevalent in certain regions and among specific populations, their overall global abuse statistics are lower than those for cannabis. *Cocaine* - **Cocaine** is a powerful stimulant derived from the coca plant, known for its strong psychological dependence and significant health consequences. - Its abuse is concentrated in specific geographical areas and demographic groups, making its global prevalence of abuse lower than that of cannabis.

Q: CAGE questionnaire is used in:

Alcohol dependence. ***Alcohol dependence*** - The **CAGE questionnaire** is a widely used screening tool for identifying potential **alcohol problems** and dependence. - The acronym CAGE stands for Cutting down, Annoyance by criticism, Guilty feelings, and Eye-openers, all related to drinking habits. *Opiate poisoning* - Screening for opiate use or poisoning typically involves asking about **drug use history**, conducting **urine drug screens**, and observing specific clinical signs like **pinpoint pupils** and **respiratory depression**. - The CAGE questionnaire is not designed to screen for opiate use. *Dhatura poisoning* - **Dhatura poisoning** is characterized by anticholinergic symptoms like **dilated pupils**, **dry mouth**, **tachycardia**, and **delirium**. - Diagnosis relies on clinical presentation and a history of exposure, not a specific questionnaire like CAGE. *Barbiturate poisoning* - **Barbiturate poisoning** presents with central nervous system depression, including **sedation**, **respiratory depression**, and **hypotension**. - Diagnosis involves a clinical assessment, history of barbiturate use, and toxicology screens, not the CAGE questionnaire.
