SAN DIEGO (CNS) - An 89-year-old woman with Alzheimer's disease who disappeared from her Mira Mesa home over the weekend is back with her family Monday morning.

Eugenia Hassell apparently wandered away from the home she shares with her husband on Flanders Drive near Greenford Drive around 5:30 p.m. Sunday, according to a San Diego police statement. Hassell has trouble remembering her own and her husband's name, and does not know her address.

Hours later, Hassell was spotted knocking on someone's door a couple blocks away and was taken home, police said.
