"We are thrilled that David has chosen the Alzheimer's Research and Prevention Foundation as his charity of choice," said Dharma Singh Khalsa, M.D., president and medical director of the ARPF. "David's choice helps to raise the profile of the need for more prevention-related research in the area of Alzheimer's, something we have been advocating since 1993. We are encouraged that his appearance on The Celebrity Apprentice will give hope to the millions of people suffering from Alzheimer's disease and those on whom they rely for their care."
