Alzheimer’s Disease
181
Senile Plaques
Complex extracellular deposits abundant in the brains of AD patients. The main
proteinaceous component of plaques is amyloid-
β
peptide.
Susceptibility Locus/Gene
A region of a chromosome or a speciFc gene that may influence the risk to a certain
condition/disease.
Familial Alzheimer’s Disease
Transmitted as an autosomal dominant trait; usually has an age of onset
<
60 years.
Sporadic Alzheimer’s Disease
Shows modest familial clustering and probably results from the synergistic action of
genetic and environmental factors. Usually has an age of onset
>
60 years.
