Is Alzheimers inherited?
According to a National Institute of Health document “Alzheimers Disease: Unraveling the Mystery”, researchers have discovered that some cases of one type of Alzheimer’s early onset AD, there seems to be a genetic link as this form runs in families. Apparently, scientists working for the NIH discovered mutations on chromosomes 21, 14, and 1 that results in production of an abnormal amyloid precursor protein (APP), an abnormal protein known as presenilin 1, and a second abnormal protein presenilin 2 respectively. “Even if only one of these genes inherited from a parent contains a mutation, the person will almost inevitably develop early onset AD. This means that in these families, children have about a 50-50 chance of developing the disease if one of the parents has it. Early-onset AD is rare and these gene mutations do not play a role in the more common late-onset AD, but as of 2002, when the NIH released this document, genetics was thought to at least partly predispose AD.
