New Alzheimer's Drugs Need To Be Developed

(Undated) -- A new study shows there is a need for more Alzheimer's drugs to be developed. Doctor Jeffrey Cummings says scientists know more about the disease now. The study found that the current drugs being developed have a success rate of only point-four percent. The Alzheimer's Association is warning that without proper treatment, there will be 16-million Americans suffering from the disease by the year 2050.
