Drugs and Alzheimer’s Disease?

This paper looks at Alzheimer’s disease (AD) which currently affects over a million North Americans.

Given the current ineffectiveness of drugs used to treat AD, what new treatment approaches may be feasible? The author looks at treatments that focuses on the development of amyloid plaques, and genetic therapy that may prove useful in treating the underlying causes of AD.
`Despite the large number of prospective and currently utilized drugs used to treat AD, none have been shown to be clearly effective. Only one drug, Tacrine, has been FDA-approved specifically to treat AD. Therefore, while research on new drugs is important, the search for the cause of AD is even more vital. Only when the cause of AD is pinpointed can drugs which hope to impair, prevent or stop the progression of AD be expediently developed. `
