New genotype is 'marker for Alzheimer's'

New genotype is 'marker for Alzheimer's'
20th January 2009

A new study has found that patients with a certain genotype can be clinically confirmed as carriers of Alzheimer's disease, according to recent reports.

Researchers based at Banner Health's Sun Research Institute found that patients with apolopoprotein E2 homozygote were susceptible to the condition, which was confirmed through a variety of tests including MRI scans and neuropsychological evaluation and testing.

Marwan Sabbagh, the lead investigator in the study and Sun Health Research Institute's chief medical and scientific officer, said the diagnosis of Alzheimer's is now "extremely accurate" and is of great help to physicians treating patients.

He commented: "This study may hold many clues to the nature of how Alzheimer's genetics work. Although clinically rare, the information gleaned in this study allows us to ask new questions and possibly answer others."

The Sun Health Research Institute was founded as a non-profit organisation in 1986 and specialises in dealing with age-related diseases.
