    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.
