It seems like everyone I know has been affected by Alzheimer's Disease in some way. For us, it's been with my Aunt Pam who is now in stage 6 of 7 of the disease.
It's frustrating and scary and sad. This is one disease that may be harder on the family and caregivers than the patient.
My cousin (Pam's daughter) Laura wrote a powerful essay on dealing with her Mom now that she is in Stage 6. It's really something.
