7 Personality Changes: The First Signs of Dementia

In this video, Dr. Alex explains the seven key personality shifts that may signal early dementia, including apathy, social withdrawal, impulsive behavior, and emotional changes. Learn how different brain regions—especially the frontal lobes—affect personality and why these symptoms are often mistaken for stress or aging. Understanding these early warning signs can help families seek medical evaluation sooner and rule out treatable causes. Early recognition can make a major difference in diagnosis, care planning, and long-term outcomes for people facing dementia.
