Study Suggests That Hitters’ Production Dips After They Return From Concussions

Concussions are not as common in Major League Baseball as they are in professional football, but they happen often enough, with players getting hit by pitches, running into walls or catching a knee in the head sliding into a base. Catchers are particularly at risk — a foul tip off the mask will snap the neck back and give the brain a solid rattle. Collisions at the plate take a toll, too.

Now, a study published in the American Journal of Sports Medicine suggests that position players in the majors who sustain concussions do not hit as effectively in their first weeks back after their injury.

Limited Rest Is Found to Help Young Concussion Patients

Interesting potential change in acute concussion care. I feel that rest is of utmost important, with the caveat that doing activities that do not provoke symptoms should be allowed, and each patient will be different, particularly depending upon the area of the brain involved and the severity of damage. 

    Experts recommend that young people who have suffered a concussion get one or two days of rest at home, until symptoms start resolving, before gradually returning to school and physical activity.

    But scientific evidence to support this approach is sparse, and some doctors have recommended that young patients remain inactive for even longer periods after a concussion.

    Now a randomized trial has compared the approaches and found that among a group of patients ages 11 to 22, those with a concussion who were prescribed strict rest for five days by staff members of an emergency department actually reported more symptoms than those told to rest for one or two days. Recovery was also slower for the group receiving stricter rest, researchers reported Monday in the journal Pediatrics.

    New Study Reveals Link to Post Traumatic Stress PTS and Attention Deficit Hyperactivity Disorder ADHD

    Concussion Predicts Post-Traumatic Stress and Attention-Deficit Hyperactivity Disorders

    April 13, 2015

    By Thomas R. Collins

    MIAMI, Florida — April 13, 2015 — Concussion predicts the development of both post-traumatic stress disorder and attention deficit hyperactivity disorder, researchers reported at the 35th Annual Meeting of the Anxiety and Depression Association of America (ADAA).

    While the effects of concussions have been generating more attention in recent years, long-term psychiatric consequences are often overlooked, explained researchers from the University of Toronto, Toronto, Ontario, Canada, at a poster presentation here on April 10. Changes in mood and function are simply seen as a post-concussion syndrome.

    Led by Melissa Furtado, BS, in conjunction with Martin Katzman, MD, University of Toronto, researchers involved 610 patients referred to the START (Stress, Trauma, Anxiety, Rehabilitation, Treatment) Clinic for Mood and Anxiety Disorders at the University of Toronto. As part of the intake process, these patients completed a Medical Intake Questionnaire, through which head injuries that resulted in a loss of consciousness or caused lingering symptoms were examined.

    A consensus between the MINI International Neuropsychiatric Interview Plus 5.0.0 (MINI Plus) and the treating physician confirmed the psychiatric diagnoses during the intake assessment. The researchers then conducted analysis of variance and t-tests to examine the association between a previous concussion and the psychiatric diagnoses.

    Their analyses demonstrated that concussions acted as a significant predictor for post-traumatic stress disorder (PTSD) (P = .002) and for attention-deficit hyperactivity disorder (ADHD) (P = .008), as well as for co-morbid PTSD and ADHD (P = .006). 

    The investigators also found that 28.6% of patients diagnosed with PTSD had suffered a concussion before their diagnosis, and 22.7% of those with ADHD had suffered a concussion. Additionally, 38.9% of those with co-morbid PTSD and ADHD had suffered a concussion.

    A link between concussions and depression did not approach significance, even though such a link was expected. “Depression wasn’t anywhere near significant, which I know is a huge focus with concussions and depression and suicidality,” noted Furtado. “We hypothesise that what is treated as depression is actually undetected ADHD in these patients. So people are diagnosed with depression and are getting treatment for it, but then are diagnosed as treatment-resistant, when it may, in fact, be undetected ADHD.”

    Furtado added that impulsivity in patients with ADHD may lead them to situations where they are prone to have concussion injuries.
