Early-onset Alzheimer's

Though the effects of the disease are similar, there are two main types. Early-onset Alzheimer's. This type happens to people who are younger than age 65. Often, they're in their 40s or 50s when they're diagnosed with the disease. When it affects older adults, though most develop normal functioning by themselves and don't require medication, some patients may have a high rate of memory loss after long-term treatment—the researchers estimate that one out of 10 can experience an average dropout for four years while developing dementia. People usually first notice symptoms during middle adulthood; once those begin occurring, more frequent diagnosis is needed so doctors know which stages overlap each other. "If you take care," says Dr. Roberts at NYU Langone Medical Center on Long Island recently before talking about his study, "his brain gets less responsive through aging." And he believes this should be prevented.

This type happens to people who are younger than age 65. Often, they're in their 40s or 50s when they're diagnosed with the disease. As a result — as opposed and not unlike what causes schizophrenia, depression, etc — dementia can be very destructive if untreated. Early-onset AD is different from milder forms because it affects much earlier on compared through brain cells dying due to aging processes such that cognitive abilities may get completely erased rather quickly for most victims of early-stage cases. It often has symptoms like memory loss, confusion over details you used many years ago (like your favorite baseball team), poor concentration, hallucinations, delusions, unusual behavior problems like paranoia, attention deficit hyperactivity disorder, trouble paying bills, social isolation, decreased self-esteem and other negative health consequences.
