Concussions are among the most common forms of traumatic brain injury (TBI), affecting millions of people each year. Many are caused by sports injury, a motor vehicle accident, a fall, or a blow to the head and can have can have lasting effects that extend far beyond the initial injury. While some symptoms are minimally detectable and last short periods of time, some concussions can cause brain injury that persists months or even years.
Understanding how concussions present, how they progress, and what tools are available to evaluate and support recovery is essential for patients, parents, athletes, and other healthcare professionals.
What Is a Concussion?
A concussion is a mild traumatic brain injury that occurs when a sudden force causes the brain to move rapidly within the skull, frequently causing the brain to head the skull. This movement can stretch, sheer, or damage brain cells leading to altered communication between neurons, and temporarily affect the brain’s normal functioning.
Importantly, a concussion does not always involve a loss of consciousness. In fact, many people remain awake and alert immediately after the injury, making the condition easy to overlook.
Common Causes an Symptoms of Concussions
Concussions can result from a variety of situations, including:
- Contact sports such as football, soccer, hockey, and basketball
- Falls, especially among children and older adults
- Motor vehicle collisions
- Bicycle or motorcycle accidents
- Workplace injuries
- Physical assaults or blunt-force trauma
Any impact to the head that causes the head or body to accelerate or decelerate rapidly has the potential to produce a concussion. Concussion symptoms can appear immediately or develop over several hours or days. Every brain and brain injury is unique, so symptoms and functional impact can vary considerably from person to person. Some common symptoms include:
Physical Symptoms:
- Headache
- Dizziness or balance problems
- Nausea or vomiting
- Blurred or double vision
- Sensitivity to light or noise
- Fatigue
- Ringing in the ears
Cognitive Symptoms:
- Difficulty concentrating
- Memory problems
- Mental fogginess
- Slowed thinking
- Trouble finding words
- Feeling “off” or disconnected
Emotional Symptoms:
- Irritability
- Anxiety
- Depression
- Mood swings
- Increased emotional sensitivity
Sleep Disturbances:
- Sleeping more than usual
- Difficulty falling asleep
- Frequent waking during the night
- Excessive daytime sleepiness
Children may demonstrate different signs, including poor regulation such increased crying, changes in eating habits, mood changes such as irritability, increased aggression, or a loss of interest in favorite activities.
Most individuals experience gradual improvement over the first two to four weeks following a concussion. After injury the brain undergoes metabolic recovery as damaged neural pathways begin restoring normal communication. During early stages after head injury, sleep is vital to brain rest and recovery. However, many times symptoms can persist.
Frequently, concussions are classified as “mild,” however the effects are not always mild. Following injury, the brain experiences changes in blood flow, glucose metabolism, inflammation, and communication between different brain regions. Even after structural healing has occurred, the brain’s functional networks may remain dysregulated.
If symptoms such as chronic headaches, ongoing cognitive difficulties, poor concentration, sleep disruption, anxiety or depression, balance problems, persistent fatigue have lasted longer than a month or two, an individual should consult with the physician and possibly begin to look into other forms of treatment.
Recovery can require a multidisciplinary approach involving healthcare providers, rehabilitation specialists, therapists, and individualized treatment strategies. Current concussion management emphasizes:
- Individualized recovery plans
- Gradual return to physical activity
- Cognitive pacing
- Sleep optimization
- Stress management
- Ongoing monitoring of symptoms
The goal is not simply symptom reduction but restoring optimal brain function. Returning to work, school, athletics, or daily activities too quickly can increase symptom severity and prolong recovery.
Each person’s recovery timeline is unique, highlighting the importance of individualized assessment and care. There is a difficulty with standard imaging such as CT scans or MRI as these tools are often used normal after a concussion, yet these tests are designed to detect structural injuries rather than subtle functional changes.
This is why clinicians increasingly recognize the value of additional tools that evaluate how the brain is functioning rather than simply how it looks.
Looking Beyond Symptoms: The Role of qEEG
One emerging tool in concussion assessment is quantitative electroencephalography (qEEG).
Unlike traditional imaging, qEEG measures the brain’s electrical activity using sensors placed on the scalp. Advanced computer analysis compares an individual’s brainwave patterns with normative databases, helping identify areas where brain function may differ from expected patterns.
Following a concussion, qEEG may reveal disruptions in communication between brain regions, altered brainwave activity, or changes in neural connectivity that are not visible on CT or MRI scans. While qEEG is not a standalone diagnostic test for concussion, it can provide additional information about brain function that may complement a comprehensive clinical evaluation. This information may help clinicians better understand persistent symptoms, monitor changes over time, and guide individualized treatment planning.
Neurofeedback Support in Concussion Recovery
Neurofeedback is a non-invasive form of brain training that uses real-time information about brainwave activity to help individuals learn to regulate their own brain function.
During a neurofeedback session, sensors monitor electrical activity while specialized software provides immediate feedback, often through visual or auditory cues, as the brain produces desired patterns of activity. Through repeated training, the brain may become more efficient at self-regulation.
For individuals recovering from concussion, neurofeedback may be incorporated into a broader rehabilitation program to address symptoms such as attention difficulties, mental fatigue, sleep disturbances, emotional regulation challenges, or cognitive slowing. Some studies have reported improvements in these areas for certain patients, although research is ongoing and results vary between individuals.
When guided by findings from a qEEG assessment, neurofeedback protocols can often be tailored to an individual’s specific patterns of brain activity, allowing for a more personalized approach to care.
A Personalized Approach to Brain Recovery
By combining comprehensive clinical evaluation with advanced functional tools such as qEEG and individualized therapies like neurofeedback, healthcare providers may be able to develop more targeted strategies that support recovery, optimize brain performance, and help patients return to their daily lives with greater confidence. Dr. Dominic DiLoreto and ThinkWell Therapy Center offer qEEG, neurofeedback, and red-light therapy to assist in early assessment, individualized care, and evidence-informed rehabilitation can make a meaningful difference in the recovery journey.
