What Causes Early-Onset Alzheimer’s Disease?Various studies have revealed that genetics play a role in roughly 80% of cases of Alzheimer’s Disease. In certain early onset cases, genetics play an even stronger role: early-onset familial Alzheimer’s Disease (FAD) can be linked to one of three gene mutations on chromosomes 21, 14 and 1. These gene mutations exist in approximately 7%-12% of younger-onset Alzheimer’s disease patients. In the majority of early onset cases, however, the causes are not well understood. Many researchers believe the causes of EOAD are the same as later-onset Alzheimer’s Disease. However, the symptoms of the disease appear to affect younger brains differently than it does older brains.
What Are the Symptoms of Early-Onset Alzheimer’s Disease?Here are the key symptoms of the disease:
- Memory loss that affects daily life
- Difficulty in problem solving
- Difficulty with making plans or organizing schedules
- Confusion when completing familiar tasks or chores
- Vision loss
- Mood changes, including depression, irritability or aggression
