Seek professional care if you experience any of the following symptoms
Personality change
Possible causes
- Alzheimer dementia (AD)
Alzheimer's disease is the most common cause of dementia. The brain shrinks, affecting memory and behavior. Symptoms worsen over time and can interfere with daily life. Increasing age raises the risk for Alzheimer dementia.
- Dissociative disorder
Dissociative disorder is a mental disorder that involves experiencing a disconnection and lack of continuity between thoughts, memories, surroundings, actions, and identity. People with dissociative disorder escape reality in ways that are involuntary and unhealthy, causing problems with functioning in everyday life.
- Progressive subcortical vascular encephalopathy
Progressive subcortical vascular encephalopathy (PSVE; also known as Binswanger disease) is a disorder in which patients develop worsening memory loss, mood changes, and gait imbalance due to cholesterol deposits and blockages in small blood vessels supplying the white matter and nerve cells (deep nuclei) under the surface of the brain. It is most common in elderly individuals with high blood pressure, active smoking, or history of stroke.
- Schizophrenia
- Adjustment disorder
- Anorexia nervosa / bulimia nervosa
