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 cases. 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
