Currently, there are two studies under way. We hope to learn more about possible changes in hormones, particularly changes involving cortisol. Our body's production of cortisol changes under conditions of stress, and also appears to be related to mood and sleep changes.
Participation involves several small blood draws on a yearly basis.
Results will be compared to age and gender-matched controls. Neural proteins and biochemicals in the CSF will be studied and compared to CSF from non-affected research volunteers. The aim of this research is to improve the diagnosis and treatment of Alzheimer's disease.
