Where Are My Car Keys? : A Mother's Journey with Alzheimer's disease

The cause of Alzheimer's disease is unknown. Would I develop the disease if my grandmother, mother, uncle and aunt had this condition?

Was it truly hereditary? Was it an affliction which plagued people who lived through World War II rations in Trinidad?

Was it related to their diet? With so many questions, and no answers, it's difficult not to worry.

Wouldn't want to become a statistic.
