One of the most common symptoms following TBI is photophobia, an intense intolerance to light that can cause significant discomfort, interfere with activities of daily living, and contribute to post traumatic headaches. It can impact the ability to work at computer screens and in well-lit offices and can cause a great deal of fatigue for patients who try to return to usual activities. Avoiding light can be very limiting. Read More
University of Toronto researchers have just published an important longitudinal study in the peer-reviewed Journal of Neurotrauma following patients with Post-Concussion Syndrome (PCS) based on a diagnosis of concussion in conformity with the international sport concussion criteria. This was the first longitudinal study that specifically excluded patients with contusions and hemorrhages identified by imaging (so-called “complicated” concussions), patients who tested positive on so-called “malingering” tests (the TOMM) and patients involved in litigation.

In a study published in April 2015 in the medical journal Brain Behavior and Immunity, a team of Canadian researchers at McMaster University presents a new understanding of the cause of the wide-array of symptoms experienced by some patients following concussion, such as headaches, dizziness, sleep disturbance, fatigue, cognitive impairment and neuropsychiatric symptoms.
This new paradigm helps to explain why the same pattern of symptoms can be found in some non-head injury patients, such a patient who has experienced infections or a patient diagnosed with post-traumatic stress disorder. It also helps to explain why some patients recover and others do not and why pre-accident experience can influence the course of post-accident recovery. Read More
Recent research has shown that traumatic brain injury, (TBI) including mild traumatic brain injury (mTBI), can damage and cause dysfunction in the pituitary gland, a pea-sized gland located in the center of the skull that releases several essential hormones affecting such functions as growth and metabolism (part of the neuroendocrine system). Researchers have found that a surprisingly high percentage of patients with persistent symptoms following a TBI show evidence of neuroendocrine dysfunction.
It turns out that the anatomy of this gland makes it particularly susceptible to the sheering injuries seen in TBI. The most common dysfunction found after TBI is deficiency in the Growth Hormone (GH), one of the key hormones released by the pituitary gland. The symptoms of GH deficiency overlap with many persistent TBI symptoms including fatigue, poor memory, depression, emotional lability, lack of concentration and attention difficulties. Read More
The American Academy of Sleep Medicine has announced the results of a recent study showing that bright light therapy following Mild TBI (concussion) may improve sleep, cognitive and brain function. The study results were presented at the June 3, 2013 meeting of the Associated Professional Sleep Societies LLC and published in an online supplement to the journal Sleep. Read More
