Study Notes
Characteristics of Dementia
- Dementia is characterized by a progressive decline in cognitive function, impacting memory, reasoning, and social abilities.
- Loss of multiple separable but overlapping abilities indicates that different cognitive skills may deteriorate simultaneously, yet can be functionally distinct.
Neurocognitive Functions Affected
- Common neurocognitive functions affected by dementia include memory, language, attention, and executive function.
- An example of a function NOT commonly affected by dementia is basic sensory perceptions.
Differentiation in Dementias
- Differentiation in types of dementia is often categorized as cortical vs. subcortical.
- Cortical brain tissue primarily refers to the outer layer of the cerebral hemispheres, responsible for higher cognitive functions.
- Subcortical brain tissue refers to structures beneath the cortex, involved in motor control and emotional regulation.
'A's of Cortical Dementias
- The four 'A's that characterize cortical dementias are:
- Aphasia: Impairment in language communication.
- Agnosia: Inability to recognize objects or people despite intact sensory function.
- Amnesia: Memory loss, particularly of recent events.
- Apraxia: Difficulty in planning and executing coordinated movements.
Cortical Dementia Deficits
- Additional deficits in cortical dementia may include impaired judgment and problem-solving abilities.
- Patients typically retain basic motor functions and psychomotor speed is generally preserved until the later stages.
Emotional Impact
- Depression and anxiety are common in individuals with cortical dementia, often resulting from awareness of cognitive decline.
Conditions and Examples
- Common examples of cortical dementia include Alzheimer's disease, frontotemporal dementia, and primary progressive aphasia.
- Examples of subcortical dementia include Huntington's disease and Parkinson's disease.
Primary Result of Subcortical Dementias
- Diseases affecting subcortical structures primarily lead to movement disorders and emotional dysregulation.
'D's of Subcortical Dementias
- The five 'D's characterizing subcortical dementias include:
- Dysexecutive syndrome: Difficulty in managing and organizing tasks.
- Delay: Slower response times and processing speeds.
- Depletion: Reduced cognitive flexibility and efficiency.
- Dysphoria: Emotional instability or mood swings.
- Dysmnesia: Impaired memory, particularly for new information.
Psychological Conditions
- Individuals with subcortical dementia are more likely to experience anxiety and depression as significant psychological conditions.
- Dysmnesia is related to challenges in recalling information, more pronounced in new memories.
Misconceptions about Subcortical Dementias
- Not all cognitive functions are equally affected; some areas may remain intact while others deteriorate more prominently.
Summary of Key Conditions
- An example of subcortical dementia includes conditions like Huntington's disease, while cortical dementia examples include Alzheimer's disease and frontotemporal dementia.
