What are the 5 Symptoms of CTE?

When you hear about CTE, or chronic traumatic encephalopathy, it’s often in the context of professional athletes who have experienced repeated head impacts. But what exactly is this condition, and why is it significant? Chronic Traumatic Encephalopathy (CTE) hits hard as it’s tied to careers in sports, the lives of vets, and those dealing with continuous brain injuries. To truly support someone living with CTE, it’s vital that both they and their family comprehend exactly what this disorder entails.

What is Chronic Traumatic Encephalopathy (CTE)?

CTE is a complex brain condition often found in those with a history of repetitive brain trauma. This trauma, typically found in scenarios like contact sports, leads to progressive degeneration of brain tissue and the build-up of an abnormal protein called tau. These changes in the CTE brain can affect how a person thinks, feels, and acts. Given the common occurrence of these injuries in sports, CTE in football has become a focal point in discussions about sports safety.

The 5 Key Symptoms of CTE

Early identification of CTE’s warning signs allows healthcare providers and families to step in with effective management techniques right away. Here are five primary symptoms to be aware of:

Cognitive Impairment

Cognitive impairment is one of the primary and most distressing symptoms of chronic traumatic encephalopathy (CTE). It manifests in several ways, significantly affecting an individual’s daily functioning and quality of life. Here’s a deeper look into its primary manifestations:

Memory Loss

  • Short-term Memory Issues: Individuals may struggle to recall recent events or conversations, a symptom often initially dismissed as mere forgetfulness but indicative of deeper issues.
  • Long-term Memory Gaps: In more advanced cases, long-term memories may become patchy, affecting personal history and learned skills.

Reduced Concentration

  • Difficulty Multitasking: Managing multiple tasks simultaneously becomes a hurdle, impacting productivity and workplace performance.
  • Sustained Attention Challenges: There might be a noticeable decline in the ability to maintain focus on single tasks for extended periods, crucial for reading or detailed work.

Emotional and Behavioral Changes

Spotting CTE often starts with noticing dramatic emotional or behavioral changes. For people living with it, along with their families, these transformations can be incredibly challenging day-to-day. These changes are not just distressing but often alter the very fabric of personal relationships. Let’s break down each symptom to understand them better.

Mood Swings

  • Unpredictable Emotions: Individuals may experience rapid and inexplicable shifts from joy to sadness or calm to frustration, without any obvious triggers.
  • Impact on Relationships: These erratic changes can strain relationships, creating misunderstandings and emotional distance between loved ones.

Increased Aggression

  • Verbal Outbursts: Sudden, intense outbursts can be shocking and hurtful, making social interactions difficult and sometimes leading to isolation.
  • Physical Aggression: In severe cases, the aggression may become physical, posing safety concerns and requiring professional intervention.

Motor Dysfunction

When someone has CTE, they usually experience motor dysfunction, which makes managing their usual activities quite challenging. Living with CTE can really impact one’s ability to stay independent and enjoy life fully. Let’s take a look at the main motor issues tied to CTE.

Coordination Issues

  • Gait Abnormalities: Difficulty with walking smoothly, which may manifest as stumbling or an unsteady gait, often observed in tasks that require balance.
  • Fine Motor Skills: Struggles with tasks requiring precise hand movements, such as buttoning shirts or writing, can become frustrating and limiting.

Speech Difficulties

  • Articulation Problems: The ability to articulate words clearly may decline, leading to slurred or slowed speech that makes communication challenging.
  • Cognitive Linguistic Deficits: Beyond the physical act of speaking, finding the right words and structuring sentences can also be impaired, complicating conversations.

Depressive Symptoms

The link between CTE and depression is strong; individuals battling this condition frequently experience profound shifts in their mental health. Struggling with these kinds of symptoms can be particularly difficult since they deeply disturb one’s emotional stability and overall quality of life. Here’s a closer examination of the depressive symptoms linked to CTE:

Persistent Sadness

  • Chronic Despair: A pervasive feeling of sadness or hopelessness that lingers, making it hard to find joy in activities once loved.
  • Impact on Daily Functioning: This ongoing melancholy can significantly impair one’s ability to function daily, affecting work, relationships, and self-care.

Suicidal Thoughts

  • Risk of Self-Harm: Severe depression in CTE may manifest as thoughts of self-harm or suicide, marking a critical need for immediate psychological intervention.
  • Urgency for Support: Recognizing these thoughts as symptoms of CTE is vital for seeking urgent help, including therapy, medications, and support systems.

Difficulty with Planning and Organization

Difficulties with planning and organization are significant symptoms of chronic traumatic encephalopathy (CTE), reflecting the impact of the condition on the brain’s executive functions. These challenges can make daily life frustrating and less efficient, as they affect the ability to manage time, prioritize tasks, and make decisions. Here’s a deeper look into how these symptoms manifest:


  • Routine Disruption: Individuals may struggle to keep up with daily routines, often forgetting or overlooking regular tasks.
  • Misplacing Items: Frequently losing track of personal items, such as keys or wallets, which can add to daily frustrations and confusion.

Impaired Decision Making

  • Struggle with Choices: Even simple decisions, like selecting an outfit or deciding what to eat, can become daunting tasks.
  • Long-term Planning Difficulties: Planning for the future, such as scheduling appointments or managing finances, becomes increasingly problematic.

Understanding CTE in Context

Chronic traumatic encephalopathy statistics reveal that CTE is not just an issue for athletes; it affects a broad spectrum of individuals exposed to head impacts. Awareness and research are growing, but there’s still much to be understood about how to protect those at risk.


Spotting the signs of CTE early on can make a big difference. If you or someone close to you is showing any of these symptoms, don’t hesitate to reach out for professional help. It’s all about getting the right support and taking steps to manage the condition effectively.
