A study found that people with early-onset Alzheimer's disease (before age 65) exhibit different symptoms and health conditions than those with late-onset.
Early-onset patients were more prone to depression, dizziness, headaches, traumatic brain injuries, epilepsy, and alcohol-related problems in the five years before diagnosis.
Unlike late-onset Alzheimer's, cardiovascular risk factors like high blood pressure were not more common in early-onset cases compared to healthy individuals.
