Study Notes
Dementia Characteristics
- Characterized by decline in cognitive function, affecting memory, thinking, and behavior
- Results in impaired daily functioning and relationships
Neurotransmitters and Brain Function
- Acetylcholine is associated with transmission of impulses between nerve cells in the brain
- Decline in acetylcholine levels in the brain is associated with dementia
Alzheimer's Disease
- Most common cause and type of dementia
- Develops due to buildup of abnormal protein clumps called amyloid plaques and neurofibrillary tangles in the brain
Acetylcholine's Role
- Plays a crucial role in many cognitive functions, including memory, attention, and learning
Delirium vs Dementia
- Delirium: characterized by sudden onset of confusion, disorientation, and altered level of consciousness
- Dementia: chronic and progressive decline in cognitive function
Dementia's Impact
- Affects memory, thinking, and behavior, disrupting daily functioning and relationships
- Disrupts normal communication, problem-solving, and emotional regulation
