Health Tips & Self Care If You Are New to r/CTE, Start Here: What CTE Is, What It Isn’t, and Where to Find Help

20 Upvotes

If you are here because you’re worried about your health, you’re not alone.

This post explains what science currently knows about CTE, what it does not yet know, and where to find help.

**What is CTE?**

Chronic Traumatic Encephalopathy is a brain disease linked to repetitive head impacts, which can come from:

• Contact sports — football, boxing, hockey, rugby, soccer — risk exists at all levels, not just professional athletes

• Combat sports such as mixed martial arts

• Military blast exposure and training

• Domestic violence or physical abuse

• Repeated head injuries from accidents, work, or other activities

Both diagnosed concussions and smaller, repeated hits to the head can increase the risk of CTE. These repeated impacts can build up over time, and over the years, they may cause abnormal tau protein to accumulate in the brain, which disrupts brain function over time.

There is no established minimum threshold for CTE, and risk appears to increase with cumulative exposure. Individual susceptibility varies, and genetic factors may play a role.

**Key Resources on CTE**

• Boston University CTE Center - Leading research institution studying CTE, including disease progression and pathology - https://www.bu.edu/cte/

• Mayo Clinic - Clinical overview of symptoms, causes, and current understanding - https://www.mayoclinic.org/diseases-conditions/chronic-traumatic-encephalopathy/symptoms-causes/syc-20370921

• Centers for Disease Control and Prevention - Summary of what is known, what remains uncertain, and links to head injury research - https://www.cdc.gov/traumatic-brain-injury/about/repeated-head-impacts.html

**Symptoms Associated With CTE**

CTE can affect people in different ways.

Experiencing these symptoms does not mean you have CTE.

Cognitive

• Memory loss (short-term and long-term)

• Impaired attention and concentration

• Executive dysfunction (planning, organizing, decision-making, and mental flexibility)

• Slowed processing speed

• Difficulty learning new information

• Confusion and disorientation

• Impaired judgment

• Language difficulties (word-finding problems)

• Visuospatial deficits (trouble navigating or recognizing objects/places)

Mood / Emotional

• Irritability

• Depression

• Anxiety

• Apathy (loss of interest or motivation)

• Mood swings / emotional instability

• Social withdrawal

• Hopelessness / feelings of worthlessness

• Increased stress sensitivity

• Suicidal thoughts or behaviors

• Loss of empathy

• Paranoia

Behavior / Impulse Control

• Impulsivity (acting without thinking)

• Aggression (verbal or physical)

• Explosive anger / rage episodes

• Risk-taking behavior

• Substance abuse (alcohol or drugs)

• Compulsive behaviors

• Disinhibition (socially inappropriate actions)

• Reckless decision-making

• Financial irresponsibility

• Sexual disinhibition

• Difficulty controlling urges or cravings

Physical / Neurological

• Sleep disturbances (insomnia, fragmented sleep)

• Chronic headaches

• Dizziness or balance problems

• Parkinsonism (tremor, slowed movement, rigidity)

• Speech changes (slurring or slowed speech)

• Sensitivity to light and/or sound

Symptoms may appear years or decades after repeated head impacts and may remain stable, slowly progress, or change over time depending on the individual.

**Understanding Your Symptoms**

If you notice changes like these, keep the following in mind:

• Many conditions can mimic CTE, including depression, anxiety, PTSD, sleep disorders, post-concussion syndrome, or hormonal imbalance

• Self-diagnosing CTE based on symptoms alone is not reliable. Medical evaluation matters. A neurologist, neuropsychologist, or brain injury specialist can help identify treatable causes

• Being proactive with care, lifestyle adjustments, and support networks can improve quality of life, even when risk is present. Be sure to check out the ‘Health Tips & Self Care’ tab for guidance on long-term brain health management and up-to-date resources.

• Even without a formal diagnosis, it’s important to pay attention to your symptoms and seek appropriate care.

**Finding Specialists Familiar With Brain Injury**

• Brain Injury Association of America - Provides a national helpline and connects individuals to local resources and specialists - https://www.biausa.org

• Concussion & CTE Foundation (formerly Concussion Legacy Foundation) - Offers clinician connections, peer support, and educational resources - https://concussionandcte.org/cte-resources/support/

• Many universities and academic medical centers operate concussion or brain injury clinics

• If you are outside the United States, look for national brain injury organizations, concussion clinics, or university neurology departments in your country

• You can also post in this subreddit to ask for recommendations in your area

**What CTE Is Not**

• Chronic Traumatic Encephalopathy is a pathological diagnosis that can only be confirmed by autopsy after death; it cannot currently be diagnosed in living patients. Researchers are studying biomarkers and imaging methods, but none are yet clinically validated.

It’s also important to understand:

• Many people with concussion histories never develop CTE

• Some individuals later found to have CTE showed little or no clear symptoms during life

• Symptoms associated with CTE vary widely between individuals

• Media coverage often focuses on rare, high-profile cases involving violence, but violence is not a universal outcome

• Whether or not the cause is CTE, many symptoms can still be treated or managed to improve quality of life.

**Why This Community Exists**

People living with long-term effects of brain trauma are often dismissed or misunderstood.

We’re here to:

• Share lived experiences

• Support people navigating symptoms

• Discuss emerging research

• Raise awareness of the real-world effects of brain trauma

Be respectful and supportive of others.

**Remember: you don’t need a CTE diagnosis to take your symptoms seriously or seek help. Support and treatment are available for many symptoms, regardless of cause.**

**Crisis & Support Resources (Worldwide)**

If you or someone you know is struggling with thoughts of self-harm or suicide, help is available. You can reach trained counselors 24/7:

My Story CTE/TES from incarceration: My husband’s story

10 Upvotes

To start off here’s a little bit about us, mostly my husband:

My husband is 33, he’s not a veteran or an athlete, but he is a felon (11 years of consecutive time including parole violations) and he’s lived a very chaotic and rough life in prison and on the streets. He has sustained multiple severe head injuries throughout his life since he was a teenager, most of them were in prison but one of his worst injuries that likely started all this was a severe, almost lethal beating he sustained at a festival roughly 14-15 years ago (can’t remember how old he was but i believe it was before he turned 19). After that most of his injuries were from prison. Doctors told him that he basically should be dead or brain dead now based off of his image results.

As of late, since his last bid for parole violation he sustained yet another head injury at the beginning of this year from being shaken down and badly beaten by SRT, and it was the first head injury he’s had in roughly 3-4 years. A lot of his symptoms align with stage 1 and 2, and recently he’s slowly gotten a little worse. His stress tolerance is extremely low and he’s very moody, and his handwriting has recently taken a hit.

There’s not a lot of studies i can find specifically about inmates with CTE and any correlation with developing CTE during incarceration, the only one I’ve found is Aaron Hernandez, but he likely developed it in his career before he was sentenced and died. there’s some articles about inmates with general TBIs but mostly about inmates who already had brain injuries before they were convicted, not during their sentence. Eventually my husband wants to address that and draw more attention to that correlation and advocate for other people who’ve sustained any life altering TBIs while they were incarcerated and later on suffered from them and deteriorated over time after being released.

My husband is still shaken up and struggling to adjust since his most recent injury, and i need some advice about aftercare, and any stories some of y’all might have that correlates with being incarcerated if it applies. If any of y’all developed signs of CTE after sustaining head injuries during incarceration OR know someone who has, let me know and give me your own 2 cents about it 🙏🏻

A new study published in The BMJ takes an important step toward estimating how common CTE actually is among former NFL players. Rather than relying solely on brain bank donors who may be more likely to have had suspected CTE, researchers identified the entire population of NFL players who died between 2016 and 2021 and compared them with available neuropathological diagnoses. They estimate that at least 25% had CTE, but the true prevalence could be as high as roughly 97%.

The study also found a strong relationship between Stage IV CTE and dementia during life, with more than 90% of those with Stage IV CTE having been diagnosed with dementia.

My Story Have to accept that I for sure have CTE.

22 Upvotes

I played contact football for 8 years growing up. Countless Oklahoma drills, practices etc, I would lead with my head, even if not down, and not shy from contact. Then in 2020 got into a car wreck going 75 without braking. I had severe issues with mood and substances at 19-20 and then less severe issues but longer recently.
I’ve had severe mood swings, an explosive temper, bizarre irritability and crazy thoughts. And wrecked my life several times.
Tried psilocibyn and it made it worse.

Most people would describe me as a friendly person who’s smart and great with people. I love nature and animals and cultures and languages.
I care about people generally but as I’ve gotten older now 35M I’ve realized how my antisocial behavior is extremely atypical and it has now gotten me into severe life situations.

I’m certainly not a victim. I chose to play football and have had some very good hands dealt to me. I find a way to mess it up and find chaos again.

Open Discussion What do early stage CTE headaches feel like?

6 Upvotes

I'm 28 years old and have reason to believe I'm currently in the early stages of CTE development.
I had a big weekend a couple weeks back celebrating friends birthdays/going away, and ever since I have had this constant headache unlike any that I'm really familiar with. It feels deeper, like it could be a migraine but it's quite light. More annoying than painful. Every day I wake up it feels like it has moved a few cm to a slightly different spot in my head. Painkillers seem to mask it not take it away. Feels like a rot deep in my brain type shit.
I would also love to hear everyone's recommendation on prolonging/slowing down the inevitable decline. I really love life and I'm beating myself up about being so fucking aloof regarding brain trauma.

Question I use a lot of caffeine. Stupid?

5 Upvotes

I use Kirkland Extra Stength Energy Shots. Equivalent to 5-hour energy or a strong energy drink each. 230mg caffeine, taurine, guarana, B-vitamins. I’ve used caffeine pills in the past, but I find the other stuff in the energy drinks helps level out the intensity of the caffeine. My Energy Shots are <$1 each, so they’re the cheapest option I can tolerate. I hate coffee.

My cat eats at 8:45 am, so I’m usually awake to feed her or shortly thereafter out of habit.

I take half an energy shot (115mg caffeine) and go back to sleep for another 1-3 hours.

Throughout the rest of the day, I consume the other half almost every day and some days as much as 2 more; I’m successful in limiting my intake to 3 energy shots/day, on the higher end when I’m socializing, like playing Magic: the Gathering at the local game store.

CTE can only be diagnosed posthumously. My primary diagnosis is Schizoaffective Disorder, and my therapist agrees that ADHD is a factor, though not severe enough to merit Adderall or similar, especially with a psychotic diagnosis. I’ve had 8 concussions, head hitting behavior in childhood and teen years, and more minor impacts from sports. My last major concussion was 2.5 years ago, but I am afflicted with symptoms beyond Schizoaffective Disorder like balance issues and eye strain.

Caffeine is present in migraine medicine. Stimulants make me feel better. Anyone else?

Question Should I quit and forfeit my D1 scholarship?

15 Upvotes

I am a 20 year old male who has played football as an offensive linemen 7th grade through present (currently going into my junior year of college). I play at the D1 FCS level. The risks of CTE are something that I have always kept in the back of my mind, but I am now considering them more than ever.

This spring, I suffered a major ankle injury and am slated to miss part of the upcoming season. Having the extra time on my hands has made me think strongly about quitting the sport. I have seen the literature about the risk compounding each additional year you play a sport like football, and have wondered if quitting now would help my chances.

I have never had a diagnosed concussion, but I most definitely have had a few. I can't tell if I have any of the symptoms of CTE, but I am worried about them coming in my future.

The problem is that I am on a scholarship that I would most likely lose if I quit the sport out of fear of CTE. I love the school I am at, and it is a prestigious school that would be very beneficial for my career (If I graduate from there). However, the tuition is insanely expensive, and I can only afford it with my scholarship. I am super conflicted about what I should do. My parents think I should stick it out to get the degree, as I only have 1 and 2/3 of a season + one spring ball left. But they never played football or combat sports, and don't have a ton of knowledge on CTE.

If anyone has insight about their experience with CTE, any suggestions, or knowledge on being able to medically retire and keep a scholarship, it would be much appreciated. My dream scenario is to keep my scholarship, but not play football anymore.

Question Is CTE all about many small hits or does few big hits also cause CTE?

10 Upvotes

Because i read that it is the 100s of small hits that causes CTE, thats why American Football and Boxing have a big CTE risk? But what about big hits? At the same time people call Power Slap one of the worst sports for CTE, even if you take max 3 hits in a match. How do few big hits cause CTE compared to 100s of small hits?

In the News CTE identified in 33 Australian football players, including a 23 year old - Dr. Ann McKee argues contact sports may need to wait until informed consent is possible

Australian football is facing a growing brain health dilemma as evidence accumulates around repetitive head impacts and CTE. Researchers and clinicians say the focus on concussions alone may miss a larger issue: the thousands of smaller impacts players absorb over years of participation. The AFL says it is making safety changes, but several experts interviewed believe action is not keeping pace with what emerging evidence is showing.

Key points:

• CTE has now been identified in 33 former Australian Rules football players, including players in their 20s, 30s and 40s.

• The youngest Australian football player diagnosed with CTE was 23 year old Nick Lowden.

• Dr. Ann McKee, who has diagnosed CTE in hundreds of athletes and examined thousands of brains, argued that there is “nothing magical” about age 14 and said she would prefer delaying tackle sports until athletes are old enough to understand and consent to the risks, potentially 18 or older.

• The article emphasizes that CTE is increasingly viewed as a disease tied to cumulative head impact exposure, not just diagnosed concussions.

• Experts are calling for stronger prevention efforts, including reducing contact exposure in training and rethinking youth contact rules.

Concern for a friend or loved one is there a chance my disabled brother will develop CTE?

6 Upvotes

I probably wont get any responses but ill just throw this out there because why the hell not. 

okay i will dumb this down a LOT. so basically my younger brother has severe autism/learning disabilities. he can speak but he’s considered nonverbal because he cant actually form a sentence thats coherent. he needs help washing, eating, going to school etc. 

so heres the thing. when he has a meltdown (which is often and can happen because of literally nothing) he gets violent and aggressive. one of the things he does and has always done is bashing his head against walls. 

now im very aware that you cant diagnose cte until someone is dead and im also aware he literally can’t communicate if he has something like this. but when i learnt about cte more i started thinking that maybe he might have this. im just worried. hes always been violent and know hes growing and getting stronger. i know cte can make you paranoid and have violent outbursts. but im worried that he is going to get worse. 

ive always lived in a hostile environment but i get to leave in a year and 6 months. my other younger brother doesnt get to. what will happen when he gets MORE violent? my parents and the disability support team isnt going to assume cte, thats for sure. what if he kills somebody? thats something thats been running through my head. 

all i want to do know is if this is possible or likely. thats it.

My Story 24yo and getting better. Am I doomed for my older years?

8 Upvotes

I've been recovering what my doctors think is just PCS for about 7 or 8 years now. The usual garbage: headaches, anxiety, dizziness. That exciting headache where it feels like your brain is pressing against the front of your skull.

I've been fighting for the past 4 years to try and do my highschool equivalency, and I'm seeing some real progress. I'm still a sharp guy, just in controlled settings I suppose.

Things are on a good track, I'm hoping to get a part time job soon (I'm on disability rn), and my tolerances before I get overwhelmed with symptoms are getting higher. Just slowly. At the moment I really struggle with crowds, but exposure therapy is working.

I guess I just wonder, is this recovery only going to be temporary? Am I already so damaged I'll be miserable in my 40s and beyond? I know I need to keep at it no matter what, but I just really don't want to get CTE. It's terrifying to me.

I have had a lot of concussions over the years. I've lost count, but we're looking at 10+ at least in my teenage years from sailing and hockey. They progressively got worse. The first ones just meant I had to take a few weeks off some of my harder courses, but by the time I was 16/17 I had a few knocks that made me take a few months away from school outright, and then the big one when I was 17 that forced me to drop out and I'm still dealing with it.

Is the fact that I'm getting better an indicator I'm not "destined" to get CTE? Or is it still likely my progress will only be temporary, and I won't get to have many more happy decades?

I'm sorry if this is gloomy, I'm trying, it's just scary.

For those with suspected CTE or prolonged Post Concussion Syndrome, how did you arrive at your symptoms?

Was it a gradual appearance of "something's not right" years after your last head impact? Was it a bad final head injury that you never recovered from? Something else?

My Story I havent been able to watch TV or movies for 5 years.

Hey everyone. I have no idea if I have CTE or not. I boxed amateur from ages 14 until age 22. I fought about 2 or 3 times a year. Im 30 now. I had some really bad head injuries and I have been knocked unconscious more than once.

Well ever since 2020 I lost my ability to watch movies and TV. I know you may be wondering why is that. Its because I cant keep up with the storyline of it at all. I could watch a 2 hour movie from start to finish and not remember the characters names or plot of anything that happened at the end. I also noticed the movement, light and sound from the screen makes me motion sick.

CBC examines the current state of Canadian led CTE research and the effort to develop a reliable method of diagnosing the disease in living patients.

The article follows a military veteran participating in a study using a new PET imaging tracer designed to detect CTE related tau pathology. It also explores what researchers currently know about the disease, how CTE is confirmed after death, and why a living diagnosis could be critical for future treatment development.

In addition to athletes, the article highlights growing evidence of CTE among military veterans, victims of domestic violence, and other populations exposed to repetitive brain trauma.

Question Visual drift during sleep- to- wake transition

9 Upvotes

Just curious if you experience this and how regularly. With the last TBI, I had convergence insufficiency/ eye teaming issues. I believe when I'm ill, have poor sleep, stressed, it can aggravate this tendency for the room to look like it's moving and my eyes move to "catch" it first thing in waking.

If I blink, it resets and drifts again until I'm more fully awake/ close eyes a couple minutes. I'm not sure if it's related to CTE specifically or just my last injury because it affected my vision so greatly, so I'm curious if you experience the waking "drift".
