Geriatric Psychiatry Practice Questions

Q: Dementia is present in all except:

Ganser syndrome. ***Ganser syndrome*** - Ganser syndrome is a **factitious disorder** characterized by approximate answers, not true dementia. - Patients with Ganser syndrome often present with dramatic, but ultimately **nonsensical responses** to simple questions, without a clear underlying organic cause of cognitive decline. *Lewy body* - **Lewy body dementia** is characterized by fluctuating cognition, recurrent visual hallucinations, and spontaneous parkinsonism. - It involves the presence of **Lewy bodies** in cortical and subcortical regions leading to progressive cognitive decline. *Pick's disease* - Pick's disease, a type of frontotemporal dementia, is characterized by language and **behavioral changes** due to neuronal loss. - It results in progressive **atrophy of the frontal and temporal lobes**, leading to profound cognitive deficits over time. *Alzheimer's disease* - **Alzheimer's disease** is the most common cause of dementia, characterized by progressive memory loss and cognitive impairment. - It is pathologically defined by the presence of **amyloid plaques** and **neurofibrillary tangles** in the brain.

Q: Which of the following is a cognitive disorder?

Dementia. ***Dementia*** - **Dementia** is a syndrome characterized by a significant decline in **cognitive function**, specifically in areas like memory, language, problem-solving, and reasoning. - It impairs a person's ability to perform everyday activities and is caused by various diseases that damage brain cells, such as **Alzheimer's disease**. *Intellectualization* - **Intellectualization** is an **ego defense mechanism** where a person uses excessive abstract thinking and intellectual concepts to avoid confronting emotions or internal conflicts. - While it involves thought processes, it is a psychological coping mechanism, not a cognitive disorder characterized by neurological impairment. *Depersonalization* - **Depersonalization** is a dissociative symptom characterized by a feeling of detachment from one's own body, thoughts, feelings, or actions, as if observing oneself from outside. - It's a symptom of a **dissociative disorder** or other mental health conditions, not a disorder primarily defined by cognitive impairment in the way dementia is. *All of the options* - This option is incorrect because only dementia is classified as a primary **cognitive disorder**. - Intellectualization and depersonalization are psychological phenomena or symptoms of other mental health conditions, not standalone cognitive disorders.

Q: Slow waves in EEG activity are seen in:

Delirium. **Delirium** - **Generalized slowing** of EEG activity is characteristic of **delirium**, reflecting global brain dysfunction. - This finding is often associated with **encephalopathy**, metabolic disturbances, or drug intoxication. *Depression* - EEG changes in depression are typically **less pronounced** and may involve subtle alterations in alpha rhythm, not widespread slow waves. - Depression is primarily a **mood disorder**, and while it can affect cognitive function, it does not usually cause the global cerebral dysfunction seen in delirium. *Schizophrenia* - EEG findings in schizophrenia are often **non-specific** or involve subtle changes like increased theta activity, but not generalized slow waves. - Schizophrenia is a **psychotic disorder** characterized by thought disturbances, which are not reflected as global EEG slowing. *Mania* - Acute manic episodes are generally associated with **normal EEG activity**, or sometimes increased fast activity. - Mania is a **mood disorder** characterized by elevated energy and mood, distinct from the global cognitive impairment of delirium.

Q: Global cerebral dysfunction characterised by alteration in cognitive function and consciousness is known as

Delirium. ***Delirium*** - Delirium is characterized by an **acute onset** of global cerebral dysfunction, marked by fluctuations in **attention, consciousness, and cognition**. - It is a medical emergency that can be caused by various underlying medical conditions, medications, or substance withdrawal. *Dementia* - Dementia is a **chronic** and progressive decline in cognitive function, primarily affecting **memory, language, and problem-solving abilities**, without a primary disturbance of consciousness. - While it involves cognitive impairment, its onset is typically gradual, and it lacks the acute fluctuations and prominent consciousness alterations seen in delirium. *Depression* - Depression is a **mood disorder** characterized by persistent sadness, loss of interest, and other emotional and physical symptoms, which can affect concentration and memory. - It does not involve a primary alteration in consciousness or the acute, global cognitive dysfunction characteristic of delirium. *Acute anxiety* - Acute anxiety is a state of intense fear or uneasiness, often accompanied by physical symptoms like palpitations and shortness of breath. - While it can interfere with focus and concentration, it does not represent a global cerebral dysfunction or an alteration in consciousness in the way that delirium does.

Q: Dementia of Alzheimer's type is not associated with one of the following

Cerebral infarcts. ***Cerebral infarcts*** - **Cerebral infarcts** are characteristic of **vascular dementia**, where brain damage is caused by reduced blood flow due to stroke or transient ischemic attacks. - While an individual with Alzheimer's could coincidentally have a stroke, **cerebral infarcts** are not a primary neuropathological feature or an expected clinical association inherent to the progression of Alzheimer's disease itself. *Delusions* - **Delusions**, particularly paranoid delusions (e.g., believing caregivers are stealing from them), are relatively common **psychotic symptoms** that can occur in later stages of Alzheimer's disease. - They are considered a behavioral and psychological symptom of dementia (BPSD) and can significantly impact the patient's and caregiver's quality of life. *Apraxia and aphasia* - **Apraxia** (difficulty with motor tasks despite intact motor function) and **aphasia** (language difficulties) are core **cognitive symptoms** that define Alzheimer's dementia. - These are progressive deficits in executive function, language, and motor skills that lead to functional impairment. *Depressive symptoms* - **Depressive symptoms**, including apathy, anhedonia, and low mood, are highly prevalent in individuals with Alzheimer's disease, particularly in the earlier stages. - They can be a reaction to the cognitive decline and loss of independence, or a direct result of the neurodegenerative process affecting mood-regulating brain regions.

Q: All are true about dementia except:

Always reversible with medication. ***Always reversible with medication*** - While some forms of cognitive impairment are reversible, **dementia** is broadly defined by a cognitive decline that is **progressive** and **irreversible** in most cases, such as in **Alzheimer's disease**. - Medications generally aim to slow progression or manage symptoms, not fully reverse the underlying pathology of most dementias. *Loss of long term memory* - **Long-term memory loss** can occur in the later stages of many dementias, although it is often more prominent than short-term memory loss earlier in some types, like **vascular dementia**. - The disease progression eventually impacts both recent and remote memories. *Impaired learning* - **Impaired learning** is a hallmark symptom of dementia, reflecting the difficulty in acquiring new information. - This is closely linked to deficits in **attention** and **working memory**, crucial for encoding new memories. *Loss of short term memory* - **Short-term memory loss** (difficulty remembering recent events or new information) is often one of the **earliest and most prominent** symptoms of common dementias, particularly **Alzheimer's disease**. - This symptom significantly impacts daily functioning and quality of life.

Q: Which of the following feature differentiates delirium from dementia?

Acute confusional state. ***Acute confusional state*** - Delirium is characterized by an **acute or subacute onset** of fluctuating attention and cognition, indicating a sudden and often reversible change in mental status. - This contrasts sharply with dementia, which typically involves a **gradual and progressive decline** over months to years. *Progressive memory impairment* - This is a hallmark feature of **dementia**, where memory loss gradually worsens over time as the disease progresses. - While memory can be impaired in delirium, its onset is acute and severe memory impairment typically only occurs in cases of **severe delirium**, not as a primary defining feature. *Visual or auditory hallucinations* - While hallucinations can occur in both delirium and dementia, they are more **prominent and vivid** in delirium, often fluctuating and contributing to the acute confusional state. - In dementia, hallucinations are usually less frequent and tend to be **more persistent**, but not typically as variable as in delirium. *Impaired communication due to cognitive decline* - Both conditions can cause difficulty with communication due to cognitive deficits, but in dementia, this impairment is **gradual and pervasive**, reflecting a chronic decline in language and executive function. - In delirium, communication difficulties arise from the **acute disturbance of attention** and can fluctuate significantly depending on the patient's level of arousal and confusion.

Q: Regarding Alzheimer's disease which is/are not true :

All of the options. ***Correct Option: All of the options*** - All three statements provided are **incorrect descriptions** of Alzheimer's disease. - In Alzheimer's disease, **short-term memory loss occurs early** (not delayed), **long-term memory is preserved initially** (not lost first), and progression is **gradual and continuous** (not step-ladder pattern). - Since all the statements are "not true" about Alzheimer's, "All of the options" is the correct answer to this negatively worded question. *Incorrect Statement: Initial loss of long term memory* - This is **NOT TRUE** for Alzheimer's disease. - Alzheimer's is characterized by **early impairment of short-term memory** (new memory formation). - Patients struggle to recall recent events or learn new information, while **long-term memories from the past** are preserved until later stages. - Remote memories (childhood, early adulthood) remain relatively intact in early-to-moderate disease. *Incorrect Statement: Step ladder pattern* - This is **NOT TRUE** for Alzheimer's disease. - Alzheimer's progression is typically **gradual, insidious, and continuous** with steady cognitive decline. - A **step-ladder (stepwise) pattern** with sudden declines followed by plateaus is characteristic of **vascular dementia**, resulting from multiple cerebrovascular events. - The stepwise deterioration reflects discrete vascular insults, not the neurodegenerative process of Alzheimer's. *Incorrect Statement: Delayed loss of short term memory* - This is **NOT TRUE** for Alzheimer's disease. - **Short-term memory loss** is one of the **earliest and most prominent symptoms** of Alzheimer's disease, not delayed. - Classic early presentations include difficulty recalling recently learned information, forgetting appointments, repeating questions, and misplacing items. - The hippocampus, critical for forming new memories, is affected early in the disease process.

Q: Clouding of consciousness is seen in:

Delirium. ***Delirium*** - **Clouding of consciousness**, characterized by reduced clarity of awareness, is a hallmark feature of delirium. - Patients with delirium often experience a fluctuating level of consciousness, disorientation, and impaired attention. *Schizophrenia* - Schizophrenia primarily involves disturbances in **thought processes**, perception, and emotion, such as hallucinations and delusions. - While cognitive deficits may be present, clouding of consciousness in the acute sense is not a primary diagnostic criterion. *Dementia* - Dementia is characterized by a **gradual decline** in cognitive function, including memory, judgment, and language. - Consciousness typically remains clear in dementia, distinguishing it from delirium where consciousness is impaired. *Depression* - Depression is a **mood disorder** with symptoms such as persistent sadness, loss of interest, and changes in sleep or appetite. - While severe depression can lead to psychomotor retardation or cognitive slowing, it does not typically involve the clouding of consciousness seen in delirium.
