My Family’s Personal Legacy of Alzheimer’s

For 20 years before his mother’s death in 2004 at age 89, actor Peter Gallagher witnessed her gradual descent into the oblivion that characterizes Alzheimer’s, the disease that also took his grandmother. Slight memory lapses in the shy, fiercely intelligent Mary Ann O’Shea Gallagher gave way over time to a profound disconnection from the present, interrupted occasionally by breakthrough moments of clarity. Gallagher immersed himself in the search for a cure. He serves on the National Advisory Council of the Alzheimer’s Association, organizes Los Angeles-chapter fundraisers, and participates in fundraising Memory Walks, all with the unshakable belief that treatments for this devastating disease will be found before too long.
