Personality Change Due to Another Medical Condition
A condition involving a persistent personality disturbance representing a change from a previous pattern, judged to be the direct physiological result of a medical condition.
Overview
Personality change due to another medical condition involves a persistent personality disturbance that represents a change from a person’s previous characteristic pattern, judged to be the direct physiological consequence of a medical condition, such as a brain injury or neurological illness.
Signs and Symptoms
Symptoms can include marked changes in emotional expression, impulse control, or interpersonal behavior that differ noticeably from the person’s prior personality. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.
Causes and Risk Factors
This condition can result from brain injury, stroke, brain tumors, epilepsy, or other neurological or medical conditions affecting brain function.
Diagnosis
A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.
Treatment
Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.
Psychotherapy
Treatment focuses primarily on the underlying medical condition, alongside behavioral strategies and family support.
Medication
Certain medications may help manage specific symptoms, such as irritability or impulsivity, depending on the underlying cause. Medication decisions should be made with a qualified prescribing healthcare professional. Do not start, stop, or change a prescribed medication based solely on information on this page.
Living With Personality Change Due to Another Medical Condition
Family education about the link between the medical condition and personality changes can improve understanding and support.
When to Seek Professional Help
Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.
Emergency Situations
If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.
Outlook
Outcomes depend heavily on the underlying medical cause and its treatability.
