Chronic Traumatic Encephalopathy (CTE) and the Long-Term Effects of Repeated Concussions
What Is CTE and Who Is at Risk?
Chronic Traumatic Encephalopathy (CTE) is a degenerative brain condition caused by repeated head injuries. This includes diagnosed concussions as well as sub-concussive impacts—smaller hits to the head that may not cause noticeable symptoms.
CTE has been most closely linked to athletes in high-impact sports like football, boxing, and hockey. But it can affect anyone who experiences repeated head trauma, including military personnel and individuals with a history of multiple concussions from falls, accidents, or recreational activities.
How Chronic Traumatic Encephalopathy Develops
CTE develops over time due to the accumulation of trauma to the brain. Even low-level, repeated impacts can lead to structural damage. One of the key features of CTE is the abnormal buildup of a protein called tau. When tau builds up in brain tissue, it forms tangles that interfere with the brain's normal function. These changes are progressive and can lead to cognitive, emotional, and physical impairments over time.
Signs of Chronic Traumatic Encephalopathy
Symptoms of CTE typically appear years after the last brain injury and tend to worsen gradually. Recognizing the early signs of chronic traumatic encephalopathy can help individuals seek support before symptoms become severe.
Cognitive symptoms
Short-term memory loss
Difficulty concentrating or solving problems
Disorientation or confusion in familiar settings
Emotional and behavioral symptoms
Irritability and mood swings
Chronic depression or anxiety
Impulsivity or increased risk-taking
Difficulty managing anger or aggression
Physical symptoms
Ongoing headaches
Balance issues, tremors, or muscle stiffness
Sleep disturbances, including insomnia or restless sleep
If you're noticing any of these symptoms after repeated head injuries, it's important to take them seriously.

Diagnosing CTE
At present, CTE can only be definitively diagnosed after death through a post-mortem analysis of brain tissue. However, ongoing research aims to improve early detection through imaging and biomarkers that could identify tau accumulation in living individuals.
Until that becomes possible, prevention and careful concussion management remain the best tools for reducing long-term risk.
The Long-Term Effects of Repeated Concussions
Not everyone who has multiple concussions will develop CTE, but the risk increases significantly with repeated or poorly managed injuries. Some of the long-term effects of repeated concussions include:
Decline in memory and attention
Mood disorders such as chronic depression
Decreased coordination and motor function
Potential development of neurodegenerative conditions
Proper recovery after each concussion is critical. Returning to activity too soon—even if symptoms appear mild—can have cumulative consequences over time.
If your concussion symptoms haven’t resolved, you’re not alone—and it’s not too late to get help.

How to Reduce the Risk of CTE
While there is currently no cure for CTE, you can take steps to reduce your risk:
Protect Your Brain
Use sport-specific helmets and protective gear
Ensure that headgear fits properly and is in good condition
Follow Concussion Protocols
Avoid returning to play or activity until cleared by a professional
Allow the brain adequate time and rest to recover fully
Stay Educated
Understand the signs of concussion and sub-concussive trauma
Advocate for safer practices in sports and physical activities
Preventing CTE starts with prevention of repeat injury and early intervention.
