Study Notes

Types of Dementia

Alzheimer’s disease characterized by atrophy in the temporal lobe.
Vascular dementia caused by single or multiple infarcts affecting blood flow to the brain.
Lewy body dementia linked to abnormal protein deposits called Lewy bodies.
Frontotemporal dementia (FTD) associated with atrophy in the frontal and temporal lobes.

Symptoms and Variants

Behavioral variant of FTD is the most common, featuring significant changes in personality and behavior.
Aphasia types include:
- Semantic aphasia: difficulty with understanding and using language meaning.
- Non-fluent aphasia: challenges in speech production.
Common symptoms across different dementias include cognitive impairment, apathy, and emotional lability.

Risk Factors

Genetic factors play a role in dementia susceptibility, especially in familial cases (e.g., familial Alzheimer's).
Non-modifiable risk factors include genetics and age.
Modifiable risk factors include lifestyle choices that could impact overall brain health.

Neurological Impairments

Damage to white matter can lead to significant cognitive decline and impaired motor functions.
Neuropsychological profiles may present with ataxia, bradykinesia, and agnosia.

Stages of Dementia

Dementia progresses in stages, typically understood as follows:
- Early stage: Mild cognitive decline, possibly reversible forms.
- Middle stage: More pronounced impairments affecting daily functioning.
- Late stage: Severe cognitive decline leading to loss of independence.

Distinction from Delirium

Dementia manifests gradually and remains stable over time, unlike delirium, which presents suddenly and can fluctuate.
Aging is a contributing factor to both conditions, but the cognitive changes in dementia are typically more severe.

Assessment

Assessment methods for suspected dementia include:
- Detailed patient history and cognitive tests (e.g., Mini-Mental State Examination).
- Evaluation of emotional and perceptive functions.
- Geriatric depression scale to assess mood-related issues.
- Attention to hearing and speech capabilities as part of comprehensive evaluation.
