Chronic Traumatic Encephalopathy (CTE)
A progressive brain condition associated with repeated head impacts, currently diagnosable with certainty only after death, involving changes in mood, behavior, and cognition.
Overview
Chronic traumatic encephalopathy is a progressive neurodegenerative condition associated with a history of repeated head impacts, such as those from contact sports, involving the buildup of abnormal tau protein in the brain; a definitive diagnosis currently can only be confirmed through post-mortem examination.
Signs and Symptoms
Symptoms can include memory problems, difficulty with planning and organization, impulsivity, mood changes such as depression or irritability, and, in some cases, progression to a major neurocognitive disorder. 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
CTE is associated with a history of repetitive head impacts, including both diagnosed concussions and more frequent, less severe impacts over time.
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 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
Symptom-focused treatment, including psychotherapy for mood symptoms and cognitive support strategies, may help manage functioning.
Medication
There is no treatment that reverses the underlying condition; certain medications may help manage specific symptoms such as depression. 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 Chronic Traumatic Encephalopathy (CTE)
Anyone with a significant history of repeated head impacts experiencing new cognitive or mood symptoms should seek medical evaluation.
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
Research into CTE is ongoing; current understanding suggests it is progressive, though individual symptom trajectories vary.
