I work as a research coordinator on Alzheimer's clinical trials. On the one hand this has been a hard year with the announcement of the failures of Dimebond and Semagacestat. On the other hand it looks like biomarkers like PET imaging and cerebral spinal fluid proteins will help us catch the disease earlier.

The Alzheimer's Association has a new service TrialMatch (1-800-272-3900) that can put you in touch with local clinical trials. Volunteering a great way to get information about the illness, potentially help yourself and others.
