Jerry Parks, a former vice president at a large Minneapolis construction company, had been the breadwinner for his family. Over time, says his wife Karen Parks, the family noticed changes. “Jerry would forget things like what time his kids’ soccer game was, and then would ask me again, forgetting that he had already asked me,” she says. Eventually, Jerry was not able to function in his high-powered position, lost his job and several jobs after that. Because Jerry was much younger than the age people tend to associate with a diagnosis of Alzheimer’s disease, the cause for Jerry’s symptoms remained unknown for years, says Karen.
