Altered Cerebral Blood Flow

This is by far the most common cause of PCS, the easiest to diagnose and the easiest to treat. A simple treadmill walking test known as the Buffalo Treadmill Test is used to determine at what heart rate symptoms occur and then can be used as a baseline for sub-symptom exercises. Sub-symptom exercises is the most important factor in overcoming PCS.

Metabolic/Inflammatory/Hormonal

ATP (energy) levels can remain depressed for up to 30 days after one concussion. Other research suggests that number goes up to 120 days if there is a second hit within that 30 day window.

Inflammatory marker, CrP, levels measured at initial injury have been shown to correlate with PCS. Higher initial inflammation levels are more likely to result in PCS. Inflammation of the brain (from any source) can cause concussion-like symptoms and most notably leaky gut syndrome has been shown to result in neuro-inflammation. That’s why diet is an important aspect of treatment for PCS.

Vestibular/Visual System

Concussions can lead to maladaptive changes in the vestibular and/or visual systems which can cause a person to have persistent dizziness. Some of the dysfunctions are easy to treat such as BPPV, others require extensive system rehabilitation known as Vestibular therapy or Visual therapy, others require referral to Neuro-optometrists. Diagnosing the correct cause of the dysfunction is very important for directing to the RIGHT treatment.

Psychological

While no one is certain the true cause of PCS, everyone can agree that all cases of PCS have a psychological component. Simply being told you have a concussion (even if you didn’t have head trauma) can cause you to have PCS symptoms. Our beliefs about our body and our diagnoses are powerful things. Other factors such as stress, emotional support, how other people in our lives respond to our condition, adequate financial support while off work, and what our doctor tells us (i.e. if they tell you you have a severe vs mild concussion) will contribute to how likely you are to recover, even once all the other factors have been resolved.

Cervical Spine Dysfunction

A concussion occurs at 90 g’s. A whiplash occurs at 4.5g’s. That means EVERY concussion results in a neck injury. The neck is home to millions of proprioceptors which help your body determine where you are in space. Dysfunction of the muscles and joints of the cervical spine can cause dizziness, headaches, migraines, nausea, and neck, head, TMJ, and facial pain which are common PCS symptoms.
