Abstract

The etiology of Alzheimer's disease (AD) still remains unknown in spite of intensive research efforts. Recent genetic linkage studies have been reported regarding some candidate genes for familial Alzheimer's disease, such as amyloid precursor protein (APP) gene and apolipoprotein E gene. On the other hand, several risk factors of AD have been revealed by epidemiological studies, including age, family history, head trauma, thyroid dysfunctions and aluminum (Al). Our study of bulk sample analysis in AD brain using neutron activation analysis showed a significant increase of Al and iron (Fe) concentrations, especially in the cerebral cortices compared with age-matched controls. Based on these results, the possible role of trace elements on the etiopathogenesis of AD is discussed.

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.

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.

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.

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.
