Study Notes
Alzheimer's Disease Overview
- Alzheimer's disease is most likely to onset in older adults, with the risk increasing after the age of 65.
- Women are more likely to develop Alzheimer's disease than men, and the risk increases with age.
Causes and Risk Factors
- The most common cause of dementia is Alzheimer's disease, accounting for 60-80% of dementia cases.
- The APOE ε4 genetic variant is associated with an increased risk of developing Alzheimer's disease.
Cognitive Decline
- As Alzheimer's disease progresses, cognitive deficits worsen, leading to significant impairment.
- The area of cognitive decline typically observed first in Alzheimer's disease is episodic memory.
- Apraxia (difficulty with coordinated motor movements) is not a common cognitive decline found in Alzheimer's disease.
Brain Pathology
- Amyloid plaques are abnormal protein deposits that accumulate outside neurons, typically occurring in the brain 10-20 years before Alzheimer's disease symptoms appear.
- Neurofibrillary tangles are twisted fibers that build up inside neurons, typically occurring in the brain 5-10 years before Alzheimer's disease symptoms appear.
- Amyloid plaques can be present in a person's brain for 10-20 years before the development of Alzheimer's disease.
Diagnosis and Imaging
- The main limitation of current neuroimaging methods for detecting amyloid plaques and neurofibrillary tangles is the inability to accurately diagnose Alzheimer's disease in its early stages.
- A definitive diagnosis of Alzheimer's disease is typically made through autopsy or biopsy.
Pathology and Brain Changes
- Amyloid plaques are typically located in the brain outside neuron cells, while neurofibrillary tangles are found within neuron cells.
- Phosphorylated Tau blocks neural impulse transmission in the axon, contributing to the development of Alzheimer's disease.
- Common brain changes observed in Alzheimer's disease include cortical atrophy, ventricular enlargement, and hippocampal atrophy.
- Brain regions that may exhibit hypofunction and/or atrophy in Alzheimer's disease include the hippocampus, temporal lobe, and parietal lobe.
Treatment and Management
- Cholinesterase inhibitors like donepezil and galantamine are used to treat Alzheimer's disease by increasing the amount of acetylcholine in the brain.
- The primary goal of cholinesterase inhibitors is to slow down cognitive decline and improve symptoms.
- Donanemab and Lecanemab are recent developments that target amyloid plaques to slow down cognitive decline.
- Mood stabilizers and antidepressants are commonly used to address mood and behavioral symptoms in Alzheimer's disease.
- Cognitive rehabilitation and stimulation focus on preserving cognitive function and improving quality of life.
- Caregivers are often educated on behavioral management and environmental changes to support Alzheimer's patients.
