Geriatric Psychiatry Practice Questions

Q: All are true regarding Fronto-temporal dementia except:

Insight present. ***Insight present*** - In Fronto-temporal dementia (FTD), **insight is typically lost** or severely impaired, particularly in the behavioral variant (bvFTD). Patients often exhibit a profound lack of awareness regarding their behavioral changes and their impact on others. - The presence of insight would argue against a diagnosis of FTD, as it is a hallmark feature of the disease's progression. *Affective symptoms* - **Affective symptoms** such as apathy, anhedonia, and dysphoria are very common in FTD, especially in the behavioral variant. These are often early and prominent features. - Patients may appear emotionally blunted or show inappropriate emotional responses. *Age less than 65 years* - FTD is a relatively common cause of **early-onset dementia**, often manifesting before the age of 65 years. - It frequently affects individuals in their 50s and early 60s, distinguishing it from Alzheimer's disease which typically presents later. *Stereotypic behavior* - **Repetitive, ritualistic, or stereotypic behaviors** are characteristic features of behavioral variant FTD. - Examples include repetitive gestures, ritualistic daily routines, or preoccupation with certain activities or foods.

Q: Not a feature of dementia is -

Loss of sensorium. ***Loss of sensorium*** - **Loss of sensorium** (i.e., altered level of consciousness or awareness) is characteristic of **delirium**, not dementia. - Dementia primarily involves a progressive decline in **cognitive function** while the patient remains alert and aware. *Loss of neurons in brain matter* - **Neurodegeneration**, involving the death and loss of neurons, is a hallmark pathological feature of most common types of **dementia**, such as Alzheimer's disease. - This neuronal loss contributes to the progressive decline in **cognitive abilities**. *Wearing of dirty clothes* - **Neglect of personal hygiene**, including wearing dirty clothes, is a common behavioral symptom in the later stages of **dementia**. - This arises from impaired executive function, **memory deficits**, and loss of insight into self-care. *Forgetfulness* - **Forgetfulness** or **memory impairment** (especially of recent events) is a primary and often initial symptom of **dementia**. - It reflects the progressive degeneration of brain regions crucial for **memory formation** and retrieval.

Q: Pseudodementia is seen in?

Depression. ***Depression*** - **Pseudodementia** is a syndrome in which a patient exhibits **cognitive impairment** that mimics **dementia** but is actually caused by a **psychiatric condition**, most commonly **depression**. - Patients with depression may experience **memory loss**, **difficulty concentrating**, and **slowed thinking** that can be mistaken for dementia. *Dissociative disorder* - Dissociative disorders involve disruptions of **memory**, **consciousness**, **identity**, and **perception**, but they typically do not manifest as a global cognitive decline resembling dementia. - While extreme stress or trauma can cause **dissociative amnesia**, it's usually specific to certain events or periods, not a generalized cognitive impairment. *Schizophrenia* - Schizophrenia is characterized by **psychosis**, **disorganized thinking**, **hallucinations**, and **delusions**, which are distinct from the cognitive symptoms of dementia. - While some cognitive deficits can be present in schizophrenia, they are typically not the primary feature and do not present as a pervasive "dementia-like" picture. *Parkinson's disease* - Parkinson's disease is a **neurodegenerative disorder** primarily affecting **motor function**, causing **tremors**, **rigidity**, and **bradykinesia**. - While **dementia** can occur in the later stages of Parkinson's disease (**Parkinson's disease dementia**), it is true dementia and not a "pseudo" condition caused by a psychiatric disorder.

Q: Dementia is seen in all except -

Schizophrenia. ***Schizophrenia*** - Schizophrenia is primarily a **psychotic disorder** characterized by delusions, hallucinations, disorganized thinking, and negative symptoms. While cognitive deficits are common, they typically involve executive functions, attention, and memory, rather than the widespread and progressive decline in multiple cognitive domains seen in **dementia**. - Although individuals with schizophrenia may experience significant cognitive impairment, it rarely leads to the profound and globally incapacitating cognitive decline that defines dementia. *Huntington's chorea* - Huntington's chorea is a **neurodegenerative disorder** that invariably leads to dementia, typically presenting as a subcortical dementia with prominent **executive dysfunction** and behavioral changes. - The cognitive decline is a hallmark feature alongside the characteristic **chorea** (involuntary movements). *Pick's ds.* - Pick's disease, now known as **frontotemporal dementia (FTD)-behavioral variant**, is a form of dementia specifically affecting the frontal and temporal lobes. - It is characterized by early and prominent changes in **personality, behavior, and language**, preceding significant memory impairment. *Alzheimer's disease* - Alzheimer's disease is the most common cause of dementia, characterized by progressive and severe impairments in **memory, judgment, language, and other cognitive functions**. - The accumulation of **amyloid plaques** and **neurofibrillary tangles** is the pathological hallmark of the disease.

Q: F00 in ICD denotes

organic disorders. ***Organic disorders - CORRECT*** - **F00-F09** in the **International Classification of Diseases (ICD-10)** Chapter V (Mental and behavioural disorders) specifically denotes **organic, including symptomatic, mental disorders** - These disorders are characterized by brain disease, brain injury, or other insult leading to **cerebral dysfunction** - **F00** specifically refers to **Dementia in Alzheimer's disease** *Mood disorders - Incorrect* - Mood disorders are classified under codes **F30-F39** in ICD-10 - This category includes conditions like bipolar affective disorder, depressive episodes, and recurrent depressive disorders *Substance use - Incorrect* - Mental and behavioral disorders due to psychoactive substance use are classified under codes **F10-F19** in ICD-10 - This section covers disorders resulting from the use of alcohol, opioids, cannabis, sedatives, hypnotics, and other substances *Psychosis - Incorrect* - Specific psychotic disorders like schizophrenia are classified under codes **F20-F29** in ICD-10 - Psychosis can be a symptom of various mental disorders, including some organic conditions

Q: All of the following are features of dementia, EXCEPT:

Clouding of consciousness present. ***Clouding of consciousness present*** - **Clouding of consciousness** is a hallmark feature of **delirium**, not dementia. Delirium is characterized by an acute, fluctuating disturbance of attention and cognition. - In dementia, consciousness typically remains clear until the very late stages of the disease, even as cognitive functions decline significantly. *Insidious in onset* - Dementia typically has an **insidious onset**, meaning symptoms develop gradually over months or years, often unnoticed initially by the patient or family. - This contrasts with the sudden or acute onset often seen in conditions like delirium or stroke. *Visual hallucinations may occur* - **Visual hallucinations** can occur in various forms of dementia, particularly in **dementia with Lewy bodies** and Parkinson's disease dementia. - While not universally present, their occurrence is a recognized potential feature of the disease. *Usually irreversible* - Most types of dementia, including **Alzheimer's disease**, **vascular dementia**, and **dementia with Lewy bodies**, are progressive and **irreversible**. - There are some treatable causes of cognitive impairment that can mimic dementia, but true dementia conditions generally do not resolve.

Q: The following are the psychiatric sequelae after stroke in the elderly: a) Depression b) Post-traumatic stress disorder c) Dementia d) Hysteria

ac. ***ac (Depression + Dementia)*** Post-stroke psychiatric sequelae in the elderly primarily include: **a) Depression** - ✓ CORRECT - Post-stroke depression affects 30-50% of stroke survivors - Results from both neurobiological changes (disruption of monoaminergic pathways) and psychological reaction to disability - Significantly impacts rehabilitation and recovery outcomes - Recognized as the most common psychiatric complication after stroke **c) Dementia** - ✓ CORRECT - Vascular dementia is a well-established consequence of stroke - Risk of dementia doubles after stroke - Cognitive impairment occurs in 20-30% of post-stroke patients - Can result from strategic single infarcts or cumulative vascular damage *b) Post-traumatic stress disorder* - INCORRECT - While PTSD can occasionally occur after severe strokes with traumatic ICU experiences, it is NOT a common or primary psychiatric sequela - Incidence is low compared to depression and cognitive impairment - Not considered a typical post-stroke psychiatric complication *d) Hysteria* - INCORRECT - "Hysteria" is an outdated term no longer used in modern psychiatric classification - NOT a recognized psychiatric sequela of stroke in the elderly - Conversion disorders are rare after stroke and have different etiology

Q: Alzheimer's disease is associated with:

Dementia. ***Dementia*** - **Alzheimer's disease** is the most common cause of **dementia**, a chronic and progressive neurodegenerative disorder characterized by a decline in cognitive function. - Key features include **memory loss**, particularly of recent events, along with impairments in language, problem-solving, and other cognitive abilities that interfere with daily life. *Delusion* - **Delusions** are fixed, false beliefs that are not amenable to change in light of conflicting evidence, more commonly associated with **psychotic disorders** like **schizophrenia**. - While individuals with advanced Alzheimer's disease can experience neuropsychiatric symptoms, including delusions, they are not the primary or defining feature of the disease itself. *Parkinsonism* - **Parkinsonism** refers to a group of neurological disorders characterized by motor symptoms such as **tremor**, **bradykinesia**, **rigidity**, and **postural instability**. - It is the hallmark of diseases like **Parkinson's disease** or **Lewy body dementia**, but not the primary feature of Alzheimer's disease, although some individuals with Alzheimer's may later develop parkinsonian features. *Delirium* - **Delirium** is an acute, fluctuating confusional state characterized by a disturbance in attention and awareness. - It is typically caused by an underlying medical condition, medication, or substance withdrawal, and is often reversible, unlike the chronic and progressive nature of Alzheimer's dementia.

Q: Which of the following is NOT true about delirium?

It has a slow, insidious onset. ***It has a slow, insidious onset*** - Delirium is characterized by an **acute** or **subacute** onset, meaning it develops rapidly over hours to days, not slowly and insidiously. - An insidious onset is more characteristic of **dementia**, which differs significantly from delirium in its course. *Characterized by fluctuating consciousness* - **Fluctuating consciousness** is a hallmark feature of delirium, where the level of awareness and cognitive function can change significantly throughout the day. - Patients with delirium often exhibit periods of **lucidity** interspersed with confusion and disorientation. *Reversible with treatment* - Delirium is often **reversible** if the underlying causes, such as infection, metabolic imbalances, or medication side effects, are identified and treated promptly. - This distinguishes it from **dementia**, which is generally a progressive and irreversible condition. *Common in elderly patients* - Delirium is indeed very **common in elderly patients**, particularly those with pre-existing cognitive impairment, multiple comorbidities, or those in critical care settings. - Their physiological vulnerability makes them more susceptible to the stressors that can precipitate delirium.

Q: Which of the following is the most prominent clinical characteristic of Alzheimer's disease?

Memory loss. ***Memory loss*** - **Memory loss**, particularly of recent events (anterograde amnesia), is the **earliest and most prominent clinical symptom** of Alzheimer's disease. - This is a **clinical characteristic** - an observable symptom experienced by the patient and noted by clinicians during evaluation. - The memory deficit progressively worsens, initially affecting **short-term recall** and learned information, eventually extending to long-term memory and significantly impacting daily functioning. *Neurofibrillary tangles* - **Neurofibrillary tangles**, composed of hyperphosphorylated tau protein, are a **pathological hallmark** found in the brains of Alzheimer's patients at autopsy or biopsy. - These are **microscopic findings**, not a clinical characteristic - they cannot be observed directly by the patient or clinician during clinical evaluation. - Essential for definitive neuropathological diagnosis but not a clinical symptom. *Amyloid plaques* - **Amyloid plaques** (senile plaques), formed by aggregation of beta-amyloid peptides, are another **pathological hallmark** of Alzheimer's disease. - Like neurofibrillary tangles, these are **microscopic neuropathological findings**, not observable clinical symptoms. - They represent the underlying disease pathology but not the clinical presentation. *Resting tremor* - A **resting tremor** is a cardinal motor symptom of **Parkinson's disease**, not Alzheimer's disease. - While some patients with advanced Alzheimer's may develop motor symptoms, resting tremor is **not a characteristic or prominent feature** of Alzheimer's disease. - This option tests knowledge of differential diagnosis between neurodegenerative disorders.
