CONCUSSIONS: SYMPTOMS AND TREATMENTS




A concussion is a type of mild traumatic brain injury (mTBI) that can shake up more than just your thinking. It often brings a mix of headaches, dizziness, fatigue, trouble concentrating, memory lapses, mood swings, and sleep disturbances. Visual symptoms—like blurry vision or sensitivity to light—are common, too, since your brain’s visual system can get thrown off by even a minor knock to the head (Frontiers in Neurology; Pediatrics; International Review of Psychiatry).

Most people bounce back within a few weeks, but about a third have symptoms that hang around longer than expected, a condition known as post-concussion syndrome (PCS) (Frontiers in Neurology; Pediatrics; International Review of Psychiatry). The initial advice is usually to rest—physically and mentally—to let the brain recover. But in recent years, research has shifted. After a brief rest, gently returning to daily activities (while paying attention to symptoms) can actually speed recovery and help prevent longer-term problems (British Journal of Sports Medicine).

When symptoms drag on, treatment often becomes a team effort. Patients benefit from learning about how concussions work, cognitive exercises to rebuild memory and focus, targeted physical therapy, and care for specific issues like headaches or vision changes (Journal of Clinical and Experimental Neuropsychology; Frontiers in Neurology). While scientists are investigating medications to address brain inflammation, there isn't a proven drug therapy yet (Frontiers in Cellular Neuroscience).

That brings us to Chronic Traumatic Encephalopathy (CTE), a rare but serious brain disease linked to repeated head impacts—even if those hits don’t always cause obvious concussions. CTE has been mostly identified in athletes from contact sports and military veterans exposed to repeated brain trauma. Unlike concussions, which usually resolve, CTE involves progressive brain degeneration that, so far, can only be confirmed after death by examining brain tissue (Harvard Health; Boston University CTE Center).

CTE symptoms may include memory loss, cognitive decline, personality changes, aggression, depression, and—in advanced stages—dementia. The disease can start developing years or decades after the injuries, and recent research has found evidence of CTE even in some young athletes who died before age 30, highlighting just how stealthy and early the process can begin (NIH; CNN).

There’s no cure or FDA-approved treatment for CTE. Care focuses on managing symptoms and improving quality of life. Scientists are actively searching for ways to diagnose CTE in living people and exploring therapies that might slow its progression (Boston University CTE Center; UCSF Clinical Trials). Prevention, though, remains the best defense: reducing repetitive head injuries by improving helmets and protective gear, changing rules in sports, and increasing awareness about the risks of concussions are all key steps (Mayo Clinic).

Approaches for Brain Protection

Given what we know about concussions and CTE, protecting your brain isn’t just a concern for athletes or soldiers—it’s critical for everyone. Here’s how you can take steps to safeguard your brain health:

  • Wear Protective Gear: Whether you’re cycling, skateboarding, skiing, or playing contact sports, always use a properly fitted helmet that meets safety standards. Helmets aren’t perfect, but they significantly reduce the risk of serious injury.

  • Enforce Safe Play: For parents, coaches, and athletes, focus on proper technique and rules that limit risky behavior—like tackling with the head in football or body-checking in youth hockey. Many leagues now have strict concussion protocols and limits on contact drills for young players.

  • Create Safe Environments: At home, prevent falls by keeping walkways clear, installing handrails on stairways, and using non-slip mats in bathrooms. For older adults, regular vision checks and balance-improving exercise can help reduce fall risk.

  • Recognize and Respond Quickly: Learn the signs and symptoms of concussion—even subtle ones. If you suspect a concussion, stop the activity and seek medical advice. Returning to play too soon increases the risk of a second, more serious injury.

  • Promote Brain Health: Regular physical activity, a balanced diet rich in omega-3 fatty acids, adequate sleep, and staying mentally engaged can all help your brain stay resilient. Managing stress and avoiding alcohol or drugs, especially during recovery, are important too.

  • Advocate for Change: Support and follow policies that prioritize player safety—like limiting contact in youth sports, requiring baseline cognitive testing, and ensuring access to trained medical staff during games and practices.

Concussions need careful handling, with rest and a gradual return to activity as the cornerstone of recovery. CTE, by contrast, is a stark reminder of the risks tied to repeated brain trauma—risks that science is still working to understand fully. Both underscore the need for vigilance and proactive steps to protect your brain, whether you’re on the field, at work, or at home.

If you’re looking for tailored advice on concussion recovery or strategies for long-term brain health, see your doctor for practical, evidence-based guidance to help you navigate the challenges of healing, prevention, and cognitive wellness.

DIABETES: PREVENTION, MANAGEMENT, AND TREATMENT Diabetes is a long-term health issue that affects millions of people, but it’s not a one-size-fits-all diagnosis. There are several types of diabetes, each with its own set of causes, risks, and ways to manage it. At its core, diabetes changes how your body handles insulin—a hormone made in the pancreas that lets your cells take in sugar from your blood and store it as glycogen for later. Without enough insulin or if your cells can’t use it properly, sugar stays in your bloodstream instead of fueling your body. The most common types are Type 1 and Type 2 diabetes. Type 1 is an autoimmune disease: your immune system mistakenly attacks the cells in your pancreas that make insulin. This form is less common and usually shows up earlier in life. There are also rarer forms, often tied to specific genes. Type 2 diabetes is the one most people know about—about 90% of diabetes cases fall into this category. It happens when your body becomes resist...

COLONOSCOPY: WHY IT'S SO IMPORTANT A colonoscopy stands as one of the most reliable ways to spot and prevent colorectal cancer before it turns into a genuine threat. What sets this screening apart is its ability to detect colon changes early—often before symptoms appear. During a colonoscopy, a doctor uses a thin, flexible tube with a light and a camera at the end (a colonoscope) to carefully examine the entire lining of your colon and rectum. If the doctor finds any polyps—small, abnormal growths that could one day turn cancerous—they can often remove them right then and there, dramatically reducing your risk of developing colorectal cancer in the future. Colonoscopy is considered the “gold standard” for colorectal cancer screening for a reason: it’s more accurate than other tests, like the fecal occult blood test (FOBT) or stool DNA tests. While those methods can sometimes miss polyps or early cancers, colonoscopy allows doctors to see and remove even small polyps directly. In fa...

  MEDITERRANEAN DIET : MAY HELP PREVENT DEMENTIA A new study brings some good news for anyone worried about dementia: what’s on your plate might matter more than your DNA. Even if you carry the genes that put you at the highest risk for Alzheimer’s, the right diet could help keep your brain healthier for longer. Scientists from Mass General Brigham, Harvard, and the Broad Institute tracked thousands of adults over several decades, examining what they ate and how their memory changed. Their findings? People who followed a Mediterranean-style diet—think lots of fruits and vegetables, whole grains, fish, olive oil, and nuts—were less likely to develop dementia and tended to keep their memory sharper as they aged. The effect was especially strong in people with two copies of the APOE4 gene, which is known to drive up the risk for Alzheimer’s. That’s a big deal, because carrying one copy of APOE4 makes you three to four times more likely to get Alzheimer’s. Two copies, and your risk jum...
