NCT02472899

Brief Summary

The study aims to identify immune biomarkers in peripheral blood for identifying Alzheimer's disease (AD). Blood samples from subjects with AD will be compared to age-matched controls without cognitive symptoms, as well as healthy younger subjects.

Sampling MethodNon-Probability Sample
Study Population

Subjects will include males and females older than 60 years diagnosed as having clinical AD according to DSM-IV criteria. The control group will comprise cognitively normal community dwelling males and females older than 60 years. In addition, a group of healthy young male and female controls aged 20-30 years will serve as the reference group. The diagnosis of both older patients and controls will be determined independently by a multidisciplinary team of experts at the Memory Clinic of the Beersheva Mental Health Center.

You may qualify if:

  • Dementia syndrome resulting from probable Alzheimer's disease

You may not qualify if:

  • Dementia syndrome caused by conditions other than Alzheimer's disease
