- Personality change
Possible Causes
Generally, Change in personality can be related to:
- Schizophrenia
A psychotic disorder characterized by disturbances in thinking (cognition), emotional responsiveness, and behavior, with an age of onset typically between the late teens and mid-30s. Hearing voices and/or believing things that aren't consistent with reality are common symptoms. The exact cause is unknown, but a mix of genetic, psychological, and environmental factors are likely responsible.
- 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.
- Adjustment Disorder
A psychological disorder, often with low mood and anxiety. It is triggered by a sudden change in life circumstances, e.g. divorce or losing a job.
