Q: A patient with depression was given Imipramine for 2 weeks. Relatives noticed increased excitement, colorful clothes, and increased talking. What is the next step in management?

Discontinue Imipramine and start Valproate. ***Discontinue Imipramine and start Valproate*** - The patient's symptoms (increased excitement, colorful clothes, increased talking) after starting an antidepressant like **Imipramine** suggest a **manic switch**, indicating undiagnosed **bipolar disorder**. - **Imipramine** should be discontinued as it can exacerbate mania, and a mood stabilizer like **Valproate** is necessary to treat the manic episode. *Continue Imipramine alone* - Continuing Imipramine would likely worsen the manic symptoms, leading to increased agitation and potential harm. - Antidepressants can trigger or worsen manic episodes in individuals with underlying bipolar disorder. *Manage with Valproate alone* - While Valproate is an appropriate treatment for acute mania, simply managing with Valproate alone without discontinuing the offending antidepressant would be suboptimal. - The continued presence of Imipramine would counteract the mood-stabilizing effects of Valproate. *Antipsychotic with Imipramine continued* - Adding an antipsychotic might manage some acute manic symptoms, but continuing Imipramine would maintain the driving force behind the manic switch. - The primary action should be to remove the causative agent (Imipramine) and replace it with a mood stabilizer.

Q: What is the most common illicit drug that causes dependence?

Cannabis. ***Cannabis*** - **Cannabis** is the most widely used illicit drug globally, and despite common misconceptions, it can certainly lead to **cannabis use disorder** characterized by dependence. - The high prevalence of its use contributes to it being the illicit drug that most commonly causes clinical dependence, as a larger user base means more individuals will develop problematic use patterns. *Cocaine* - While cocaine is known for its **highly addictive potential** and rapid development of dependence, its overall prevalence of use is lower than cannabis. - The intense psychological dependence associated with cocaine can lead to severe withdrawal symptoms and compulsive drug-seeking behavior. *Heroin* - **Heroin**, an opioid, is highly addictive, causing both **physical and psychological dependence** very quickly due to its potent effects on the brain's reward system. - However, its illicit use is less widespread compared to cannabis, making it responsible for fewer overall cases of dependence. *Amphetamine* - **Amphetamines** also have a high potential for **psychological dependence**, leading to compulsive use and significant withdrawal symptoms upon cessation. - Like cocaine and heroin, the overall number of people who use amphetamines illicitly is significantly lower than those who use cannabis.

Q: On voluntary admission, the maximum number of days a person can be admitted as per mental health care act is:

30 days. ***30 days*** - As per the **Mental Healthcare Act, 2017**, under **Section 89 (Independent Admission)**, a person can be admitted independently for a **maximum period of 30 days**. - After 30 days, the person must either be discharged or the admission must be converted to voluntary or involuntary admission with appropriate procedures. - This provision allows for independent treatment-seeking without requiring a caregiver's involvement initially. *48 hours* - **48 hours** is not related to voluntary or independent admission duration. - This timeframe relates to the period within which a voluntary patient must be discharged after they request to leave (unless there are grounds for involuntary admission). *60 days* - **60 days** is not specified in the Mental Healthcare Act, 2017 for any category of admission. - This is neither the duration for voluntary, independent, nor involuntary admission procedures. *90 days* - **90 days** is not the correct maximum period for voluntary or independent admission. - While voluntary admission can continue indefinitely with ongoing consent, **independent admission** specifically has a **30-day limit** as per Section 89 of the Act.

Q: Magnan's symptom is seen in:

Cocaine. ***Cocaine*** - **Magnan's symptom**, also known as **formication**, is a tactile hallucination where an individual perceives insects crawling under their skin, commonly associated with chronic cocaine use. - This symptom is a manifestation of **cocaine-induced psychosis** or severe intoxication, leading to paranoid delusions and abnormal sensory experiences. *Datura* - **Datura** intoxication primarily causes anticholinergic effects, such as **dry mouth**, **dilated pupils**, confusion, and visual hallucinations, but not typically Magnan's symptom. - The hallucinations associated with Datura are often described as vivid and florid, but distinct from the tactile formication seen with cocaine. *Cannabis* - **Cannabis** use can induce altered perceptions, euphoria, anxiety, and sometimes paranoia, but it is not typically associated with tactile hallucinations like Magnan's symptom. - While high doses can lead to psychotic-like symptoms, **formication** is not a characteristic feature of cannabis intoxication. *Opium* - **Opium** and other opioids primarily cause central nervous system depression, leading to euphoria, sedation, pinpoint pupils, and respiratory depression. - Opioid use is not linked to tactile hallucinations such as **formication** or Magnan's symptom.

Q: A patient complains of sadness of mood, increased lethargy, early morning awakening, loss of interest and reports no will to live and hears voices asking her to kill self. What is the diagnosis?

Major depressive disorder plus psychosis. ***Major depressive disorder plus psychosis*** - The patient presents with classic symptoms of **major depressive disorder**, including persistent sadness, **anhedonia (loss of interest)**, **lethargy**, and **early morning awakening**. - The presence of **auditory hallucinations** (hearing voices asking her to kill herself) indicates **psychotic features** accompanying the severe depression, leading to the diagnosis of major depressive disorder with psychotic features. *Schizophrenia* - While schizophrenia involves psychosis, the primary presentation here is a prominent **depressive syndrome** rather than the typical **positive symptoms (delusions, hallucinations)**, **negative symptoms (alogia, avolition)**, and **disorganized thought** processes characteristic of schizophrenia. - The depressive symptoms are too pervasive and central to the clinical picture to be solely schizophrenia. *Schizoaffective disorder* - This disorder requires a period of **at least two weeks of psychotic symptoms** (hallucinations or delusions) **without prominent mood symptoms**, which is not described. - In this case, the **psychotic symptoms are congruent with the depressed mood** (e.g., voices urging self-harm, reflecting hopelessness), rather than independent. *Schizotypal personality disorder* - This is a pervasive pattern of **social and interpersonal deficits** marked by acute discomfort with, and reduced capacity for, close relationships, as well as by **cognitive or perceptual distortions** and eccentricities of behavior. - It does not involve persistent, severe depressive episodes with overt psychotic symptoms as described, nor significant functional impairment to the extent seen here.
