Abstract

Alzheimer's disease is a degenerative disorder of the central nervous system which causes progressive memory and cognitive decline during mid to late adult life and is accompanied by a wide range of neuropathologic features including extracellular amyloid plaques and intra-neuronal neurofibrillary tangles. Four genetic loci for Alzheimer's disease have been identified. They are the amyloid precursor protein gene on chromosome 21, a gene for early onset autosomal dominant form on chromosome 14, another gene on chromosome 1, and the risk-modifying gene apolipoprotein E on Chromosome 19. The etiology is heterogeneous and complex, and additional Alzheimer's disease genes remain to be found. The genes identified in the inherited forms are now being used to understand the pathogenesis of the disease.

Basal forebrain is a region in the brain important for production of acetylcholine and is the major cholinergic output of the CNS. Discover the latest research on circuits in the basal forebrain here.

Alzheimer's Disease: APOE

Apolipoprotein E (APOE) polymorphic alleles are major genetic risk factors for Alzheimer's disease. Discover the latest research on APOE and other genetic determinants of Alzheimer's disease here.

Alzheimer's Disease: Amyloid Beta

Alzheimer's disease is a neurodegenerative disease associated with the accumulation of amyloid plaques in the brain; these plaques are comprised of amyloid beta deposits. Here is the latest research in this field.

Alzheimer's Disease: APP

Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.

ApoE Phenotypes

Apolipoprotein E (APOE) is a protein involved in fat metabolism and associated with the pathogenesis of Alzheimer's disease and cardiovascular disease. Here is the latest research on APOE phenotypes.
