progressive decline in all areas of cognitive functioning
what is the most common form of dementia
alzheimer’s disease
define Early-onset familial Alzheimer’s disease
occurs before the age of 65 and individual has a positive family history of Alzheimer;s for at least 3 generations → hereditary
a mutation in of 3 of these genes places you at greater risk for alzheimers
PS1, PS2, amyloid precursor protein
define Sporadic Alzheimer’s disease (“late onset”)
occurs after age 65 due to a combination of genes, environment, and lifestyle
describe the 3 ApoEs (Apolipoprotiens) found most important to the development of alzheimers
- ApoE2 → carrying 1 copy can reduce the risk
- ApoE3 → shows no influence
- ApoE4 →present in about 50% of those with “late onset”

mild stage: usually stay independent but may need help with certain activities to stay safe
moderate stage: diffculty communicating & performing daily tasks, behavioral & personality changes, often the longest stage
severe stage: most likely need full-time care, communication is very impaired, aggression & agitation is common, difficulty drinking & eating which can cause infection & death
what are some brain changes for alzheiemrs
- atrophy: decrease in size of an organ/tissue
- amyloid plaques: abnormal deposits that form outside the neuron
- Neurofibrillary tangles: tau components that collapse into twisted strands and occur inside the neuron → causes the inability of nutrients to move through the neuron, causing death of the neuron
describe the formation of amyloid plaques
Amyloid precursor protein (APP): protein that remains both inside and outside of the neuron, and the part that remains outside gets cut off by secretases (enzymes… see below)
Alpha-secretase: normally, cuts off the APP that remains outside the cell that has the potential to become beta-amyloid
Beta-secretase: in Alzheimer’s, cuts APP off in the wrong place which causes beta-amyloid (sticky substance) to form, which produces plaques that cannot dissolve
define tau
a protein that helps maintain the stability of microtubules which keep the parallel strands straight (of the neuronal transit system)
3 biomarkers for alzheimers
- Progressive atrophy of the brain → could be seen using CT scans
- Distribution of tangles → could be seen using PET imaging
- Predictions based on biomarkers show that these abnormalities come before the onset of clinical symptoms by at least 2 decades

increases:
–> strong:
- traumatic brain injury
- mid-life obesity
- mid-life hypertension
- smoking

–> possibly linked:
- history of depression
