Regrettably, post concussion syndrome is common in kids and not talked about enough.


Post concussion syndrome, also called persistent post concussion syndrome, is a pattern of life-altering symptoms that occur after a concussion. Post concussion syndrome can affect a child’s brain, behavior, mood, personality, and body. Though parents are usually more concerned about serious head injuries, even mild concussions can result in post concussion syndrome. A recent study found that 25% of children admitted to the emergency department with mild concussions had post concussion symptoms 6-60 months later.

However, there are proven preventative options which include taking appropriate safety precautions and neuroprotective supplements

This article will cover symptoms of post concussion syndrome in kids, ways to treat post concussion syndrome in kids, and strategies for preventing post concussion syndrome. 

Symptoms of Post Concussion Syndrome In Kids

Most children recover from concussions within 2-4 weeks. If post concussion symptoms last longer than 4 weeks, it may be time to consider having your child evaluated for post concussion syndrome. 

Mood Or Personality Changes

Post concussion syndrome symptoms may include mood or personality changes. Kids may have new or more frequent emotional outbursts or meltdowns. They may lose interest in things they used to love and develop more fears and/or anxieties. Formerly easy-going kids may become restless, withdrawn, clingy, or irritable.

Memory And Focus Difficulties

Memory and focus may suffer after a concussion. Kids may start to exhibit symptoms of ADHD, have difficulties in school, have trouble learning new games, complain of brain fog, lose confidence, seem scattered and disorganized, and have difficulty following directions. Kids may find that their thinking is slow and may seem slower than usual to respond.

Impaired Vision And Balance

Vision and balance may be affected. Kids may stop enjoying the sports and video games that they used to love. Reading may become difficult. Their eyes may be more sensitive to light. Kids may engage less in active play with their friends. They may have difficulty with car rides and complain of dizziness or motion sickness. Dizziness and lightheadedness after standing quickly may also occur. 

Increased Headaches

Kids may start to get more headaches than usual. Reading, mental focus, physical activity, bright lights, and sensory overstimulation may cause headaches. Kids may start to avoid school, shopping, and parties, and they may start to prefer quiet places. 

Decreased Sleep And Energy Levels

Sleep and energy levels may be impacted. They may have difficulty falling or staying asleep and/or may complain of being tired all of the time. They may take a long time to recover after mild exercise, overstimulation, and/or disruption to schedule. 

Integrative Treatment Of Post Concussion Syndrome

Integrative treatment of post concussion syndrome centers on four pillars:

  1. Restoring the autonomic nervous system. This addresses problems like headache, sleep problems, and dizziness after standing too quickly (aka postural hypotension).
  2. Addressing vestibular and ocular symptoms. This means addressing problems with balance and vision. 
  3. Calming neuroinflammation. This addresses problems with fatigue, brain fog, slow thinking, memory, depression anxiety, and PTSD. 
  4. Balancing neurotransmitters. This is important for cognitive function, memory, and mood. 

Each person with post concussion syndrome will experience a different pattern of the above groups of symptoms and will need individualized treatment. Some people may only experience one or two of the above types of symptoms while others may experience all four. Working with an experienced professional is a requirement for proper treatment.

Note: Post Traumatic Stress Disorder (PTSD) often co-occurs with post concussion syndrome. Make sure that your child is evaluated for both because the symptoms often overlap, but the treatments are different. 

Treatment To Restore The Autonomic Nervous System After A Concussion

The autonomic nervous system could also be called the automatic nervous system. It controls all the unconscious processes that keep the body functioning without thinking about it. Things like sleep, energy levels, digestion, heart rate, blood pressure, sweating, and breathing are all affected by the autonomic nervous system.

The two modes of the autonomic nervous system are parasympathetic or “rest and digest” and sympathetic or “fight-fight-freeze,” and the body’s ability to switch easily back and forth between them is essential to good health. 

Healing the autonomic nervous system is a huge topic and there are many strategies available. Making sure that the gut-brain connection is healthy is an important first step. Counseling, therapy, or yoga to instill a sense of safety in the body and in the world could be important for some kids. Connection with family, community, and nature is essential. Relaxing herbs that work to restore the neuroendocrine system may be helpful aids for some kids to balance the nervous system. 

Addressing Vestibular (Balance) and Ocular (Eye) Issues

Vestibular-ocular dysfunction is common after a concussion, especially in athletes. It causes symptoms like dizziness, blurred vision, motion sensitivity, nausea, and balance problems.

Vestibular rehabilitation therapy, cervical spine assessment and therapy, and gentle exercise may be helpful. Any exercise or exertion that occurs after a concussion should be low level and halted before it causes any symptoms. Taking it easy is much more important than pushing through pain at this stage of healing. 

Magnesium is important for the ocular-vestibular system and should be considered for kids with these symptoms. 

Calming Neuroinflammation

Neuroinflammation causes symptoms like brain fog, depression, irritability, difficulty managing anger, memory problems, and fatigue. It can occur after brain injury if the brain fails to restore inflammatory balance after the acute phase of healing. 

Eating an anti-inflammatory diet and living an anti-inflammatory lifestyle are foundational aspects of calming neuroinflammation after a traumatic brain injury. 

Melatonin is an important anti-inflammatory molecule and there is evidence that it can improve symptoms like sleep disturbances and depression associated with post concussion syndrome. Omega 3 fatty acids, astaxanthin, moringa, and curcumin are other anti-inflammatory supplements that may be helpful. 

Balancing Neurotransmitters

Neurotransmitter balance in the brain can shift after injury, leading to changes in mood, cognition, and behavior. Prescription antidepressants that affect serotonin (a neurotransmitter) are a common conventional treatment for post concussion syndrome. 

Many different herbs and nutraceuticals are available for rebalancing neurotransmitters. One of my favorite brain supplements for kids is L-Theanine. L-Theanine is an amino acid found in green tea and it helps with anxiety, focus, memory, sleep, and more. 

Prevention of Post Concussion Syndrome

Preventing post concussion syndrome is easier and more effective than treating it. Prevention of post concussion syndrome focuses on using proper physical protection when driving and playing sports. Minimizing risk factors, using preventative neuroprotective supplements, and early treatment of concussion are other important aspects of prevention.

Using Proper Protection When Driving & Playing Sports

Seatbelts, helmets, mouthguards, and handrails are important for preventing falls and blows to the head. Prevention is key to reducing risk of injury!

Minimizing Risk Factors

Risk factors for developing post concussion syndrome include stress, social difficulties, and nutrient deficiency. Helping kids manage stress after a head injury will help them to recover more quickly. It is important to understand that kids with social difficulties may have a slower recovery trajectory and may require more support from their parents and families during recovery.

Vitamin D deficiency may be associated with an increased risk of problems after traumatic brain injury. Pro-inflammatory diets and diets low in omega 3 fatty acids may also lead to greater symptoms after brain injury. 

Neuroprotective Supplements

Neuroprotective supplements to prevent head injury and post concussion syndrome are a new area of research. Promising neuroprotective supplements include vitamin D, omega 3 fatty acids, curcumin, lion’s mane, choline, melatonin, folic acid, and CBD from cannabis. 

Early Treatment Of Concussion 

Early treatment of concussion may help to prevent more serious post concussion symptoms. Physical and mental rest are of utmost importance after concussion. Minimal screen time, plentiful rest, and light physical activity are recommended. 

Magnesium, omega 3 fatty acids, vitamin D, and melatonin are the most important acute concussion supplements in my practice. I also give homeopathic arnica to all of my pediatric head injury patients and I often follow that with homeopathic natrum sulfuricum if they have persistent symptoms. 


Post concussion syndrome can have serious effects on a child’s physical, mental, and emotional health. There are a variety of possible symptoms and treatment should be tailored to each individual. Prevention is key and involves physical protection and injury prevention, proper early treatment of concussion, anti-inflammatory nutritional support, and awareness of risk factors.
