Q: Which of the following is a key distinguishing feature of delirium compared to dementia?

Acute onset of confusion and disorientation. ***Acute onset of confusion and disorientation*** - Delirium is characterized by a **sudden (acute) onset** of mental status changes, including fluctuations in attention, awareness, and cognition, often presenting as **confusion and disorientation**. - Its symptoms typically develop over hours to days, contrasting sharply with the more chronic and insidious progression of dementia. *Gradual memory loss* - **Gradual memory loss** is a hallmark symptom of **dementia**, a neurocognitive disorder characterized by a progressive decline in cognitive function over months to years. - While memory impairment can occur in delirium, its onset is rapid and associated with a fluctuating course, not a steady decline. *Visual hallucinations* - While visual hallucinations can occur in **delirium**, they are not its most unique distinguishing feature from **dementia**, as they can also be prominent in certain types of dementia, such as **Lewy body dementia**. - The acute, fluctuating nature of **cognitive impairment** is a more defining characteristic of delirium. *Difficulty in recognizing familiar people* - **Prosopagnosia** or the inability to recognize familiar faces, is a symptom that can manifest in advanced stages of **dementia** due to widespread brain atrophy. - While patients with delirium might appear confused or disoriented to the point of not recognizing familiar individuals, this is usually part of a global, acute cognitive impairment and not a primary, isolated deficit.

Q: A 55-year-old chronic alcoholic male, presented with irrelevant talks, tremor and sweating. He had his last drink 3 days back. What is the probable diagnosis?

Delirium tremens. ***Delirium tremens*** - The presentation of **irrelevant talks**, **tremor**, and **sweating** in a chronic alcoholic who stopped drinking 3 days prior is highly characteristic of **delirium tremens**. - **Delirium tremens** is a severe form of acute **alcohol withdrawal**, typically occurring 2-4 days after the last drink, and involves extreme agitation, disorientation, hallucinations, and autonomic hyperactivity. *Korsakoff psychosis* - **Korsakoff psychosis** is a chronic neuropsychiatric syndrome associated with **thiamine deficiency**, often seen in chronic alcoholics. - It primarily presents with severe **anterograde and retrograde amnesia**, **confabulation**, and **apathy**, rather than acute, fluctuating consciousness and autonomic instability seen in delirium tremens. *Post-Acute withdrawal syndrome* - **Post-Acute Withdrawal Syndrome (PAWS)** involves persistent, milder symptoms that can last weeks or months after acute withdrawal. - Symptoms are generally less severe and acute than described, often including mood swings, anxiety, sleep disturbances, and cognitive impairment, not the acute delirium and autonomic overactivity presented. *Discontinuation syndrome* - **Discontinuation syndrome** refers to a cluster of symptoms that can occur after stopping or reducing certain medications, particularly antidepressants. - It is not directly related to alcohol withdrawal and typically presents with symptoms like dizziness, nausea, sensory disturbances, and flu-like symptoms.

Q: Which of the following statements about Alzheimer's disease is false?

Alzheimer's disease is curable.. ***Alzheimer’s disease is curable*** - Alzheimer's disease is currently **incurable**, and treatments primarily focus on managing symptoms and slowing disease progression. - Research is ongoing to find more effective treatments, but there is no known cure yet. *Alzheimer’s disease is a leading cause of cognitive decline.* - Alzheimer's disease is the **most common cause of dementia**, accounting for 60-80% of cases, making it a primary driver of cognitive decline in older adults. - The disease progressively damages brain cells, leading to a decline in memory, thinking, and reasoning abilities. *Alzheimer’s disease causes dementia.* - **Dementia** is the clinical syndrome characterized by significant cognitive decline, and Alzheimer's disease is the most common underlying cause. - The characteristic pathological changes in Alzheimer's (amyloid plaques and neurofibrillary tangles) lead to neuronal damage and the resulting dementia symptoms. *One in 10 people age 65 and older has Alzheimer’s disease* - This statement accurately reflects the prevalence of Alzheimer's disease, as approximately 11.3% of people aged 65 and older in the United States have Alzheimer's dementia. - The risk of developing Alzheimer's disease **increases with age**, making it more common in the older population.

Q: Which condition is characterized by ejaculation that occurs sooner than desired, typically within one minute of vaginal penetration, and causes distress to the individual or partner?

Premature ejaculation. ***Premature ejaculation*** - It is defined by ejaculation that **occurs sooner than desired**, typically within **one minute of vaginal penetration**, and causes significant distress. - This condition can be lifelong or acquired, and often impacts **sexual satisfaction** and **relationship quality**. *Erectile dysfunction* - This condition involves the **inability to achieve or maintain an erection** firm enough for satisfactory sexual intercourse. - While both can affect sexual function, **erectile dysfunction** is about erection quality, not the timing of ejaculation. *Retrograde ejaculation* - This occurs when semen, instead of exiting the penis, **travels backward into the bladder** during orgasm. - It results in a **"dry" orgasm** or very little semen expelled, but does not primarily relate to the timing of ejaculation. *Antegrade ejaculation* - This term describes **normal ejaculation**, where semen is expelled forward through the urethra and out of the penis. - It is the **physiological opposite** of retrograde ejaculation and does not describe a dysfunctional timing of ejaculation.

Q: What is the current preferred term for the condition previously known as mental retardation?

Intellectual disability. ***Correct: Intellectual disability*** - This term was adopted to replace "mental retardation" due to its less stigmatizing nature and its focus on **cognitive and adaptive functioning** - It emphasizes the need for supports and services to help individuals achieve their potential, rather than simply labeling a deficit - Officially adopted in **DSM-5 (2013)** and mandated by **Rosa's Law (2010)** in federal terminology *Incorrect: Feeble Mindedness* - This is an **outdated and derogatory term** that was used historically to describe individuals with cognitive impairments - Its use has been discontinued due to its negative and dehumanizing connotations *Incorrect: Madness* - This term typically refers to severe **mental illness** or **psychosis**, not intellectual impairment - It is an informal and often stigmatizing term that is not used in clinical or diagnostic contexts for intellectual functioning *Incorrect: Mentally unstable* - This term is often used to describe individuals experiencing **fluctuations in mood**, **behavior**, or **thought processes**, usually associated with mental health conditions - It does not specifically refer to global cognitive deficits or intellectual functioning [Practice more Psychiatry PYQs on OnCourse]
