Among the chronic symptoms seen in these children were forgetfulness, memory problems, sensitivity to light and noise, ADHD and even psychological problems. Sadly, many of these children had been misdiagnosed as suffering from unrelated ADHD, sleep disorders, depression, etc. This misdiagnosis, the researchers noted, leads to treatment that is not suited to the problem, thus causing the children prolonged suffering.

Post Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI) have been often been viewed as two distinct conditions, one with an “emotional” cause and the other with a “physical” cause. It has been recognized for some time that these conditions can produce similar symptoms, such as problems with sleep, concentration, memory and mood. As noted by the authors of a literature review published in Current Neurology and Neuroscience Reports, “increasingly symptoms previously presumed to be specific to PTSD or TBI are being identified in both disorders.” These include symptoms more commonly associated with TBI such as headache, dizziness, balance and vision problems. Evidence has also demonstrated that patients with a history of TBI are more likely to meet criteria for PTSD than others with similar intensity injuries and that patients who are also diagnosed with PTSD are significantly more likely to report persistent cognitive or sensory problems after a TBI.

Several of my traumatic brain injury (TBI) clients have been treated for gut issues – issues that were not present prior to their TBI. Insurers, of course, insist that this treatment cannot be related to the brain injury. The scientific literature indicates otherwise. Researchers at the University of Maryland School of Medicine recently found a two-way link between TBI and intestinal changes.
The findings indicate that this two way interaction may contribute to increased infections in TBI patients and may also worsen chronic brain damage. Read More
A review published in the September 2017 issue of Frontiers in Neurology proposes use of “systems science” to better understand concussion diagnosis and prognosis. This is a discipline that analyzes complex problems as whole systems and integrates research findings from different disciplines. In explaining the need for a systems approach, the reviewers note one description of concussion that is uniformly recognized – that it is a highly heterogeneous phenomenon, with numerous factors interacting dynamically to influence an individual’s recovery trajectory. (This concept is highlighted in the title of one of the Concussion WebCasts made available by the American Association of Family Physicians : “If you have seen one concussion, you have seen one concussion.”) Read More
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
In recent years a great deal of research has been done to identify an objective “biomarker” of concussion. As reported in this blog, some promise has been found in blood biomarkers (measuring plasma tau protein levels) and neuroimaging, such as the DTI MRI sequence. Unfortunately, these approaches are invasive and/or expensive and are not always a reliable indicator of concussion and concussion recovery. As reported in our November 27, 2016 blog post, until now, one of the most promising concussion screening tools was a series of vision tests endorsed by the Department of Defense.
Scientists at Northwestern University have now found a related, and what appears to be an even more precise and accurate tool, a measure of the brain’s electrophysiological response to sound. Read More
In our May, 2014 post, we reported on research showing that traumatic brain injury, including mild traumatic brain injury (mTBI), can damage and cause dysfunction in the pituitary gland resulting in deficiencies in key hormones released by the pituitary gland, such as Growth Hormone (GH). As we explained in that post, the anatomy of the pituitary gland makes it particularly susceptible to the sheering injuries seen in TBI. These hormone deficiencies can produce many of the persistent symptoms seen following a TBI, such as fatigue, poor memory, depression, anxiety, emotional lability, exercise intolerance, lack of concentration and attention difficulties. (Although not always the case, these deficiencies can also produce physical symptoms, such as increased fat mass – especially in the abdominal area – and increased cholesterol.) We also noted findings showing that pituitary dysfunction can worsen over the five year period following an injury – in other words, that this is an issue that deserves to be monitored on an ongoing basis.

Several recent developments demonstrate increasing recognition of the serious potential consequences of concussion, and commitment to minimize those consequences through appropriate treatment of concussion:
Physicians have an ethical obligation to become knowledgeable about concussion.
On June 9, 2014 the American Academy of Neurology, the largest professional association of neurologists, released a position paper stating that doctors have an ethical obligationto educate and protect athletes from sports concussion and clear them to play only when the athlete is medically ready, standing firm against objections from players, athletes and coaches. The statement declares that sports concussion “is a major issue in the world of health care” and requires more attention from physicians. Read More
