Barriers to and facilitators of return to learning following a sport-related concussion: Perspectives of female secondary school students.

OBJECTIVE: To identify barriers to and facilitators of return to learning (RTL) for female secondary school students following a sport-related concussion (SRC), and to identify critical junctures on the injury-to-recovery continuum that can be targeted to enhance the RTL process. DESIGN: A grounded theory approach using in-depth qualitative interviews. SETTING: Secondary schools within the York Region District School Board in Ontario. PARTICIPANTS: Ten female secondary school students who presented to a sports medicine physician with an SRC in 2015 or 2016. Five of the students received a Green Folder intervention containing an RTL strategy, while 5 students received no RTL intervention following their SRC. METHODS: In-depth interviews were conducted in person or by telephone. All interviews were audiorecorded and transcribed. The transcriptions were analyzed, coded, and examined for common themes by 2 independent reviewers. MAIN FINDINGS: Barriers to RTL included a lack of a graduated RTL process, students' own internal stress, poor communication of expectations, lack of concussion education, and inadequate support from teachers. Facilitators of RTL included academic accommodations and having a primary contact person within the school system. Owing to inconsistent implementation, the impact of the Green Folder intervention as a facilitator of RTL remains unknown. CONCLUSION: Results of this study support existing findings in the realm of concussion research. A novel finding includes the importance of a primary contact person as a facilitator of RTL. This person could help to overcome some of the identified barriers to RTL and improve outcomes by assisting with academic accommodations, providing reassurance regarding these accommodations, improving education among teachers and students, and enhancing communication between stakeholders.

Relapse of concussion symptoms in the context of premature return to learn and return to play: Comparative analysis of 2006 to 2011 and 2011 to 2016.

OBJECTIVE: To determine whether the proportion of sport-related concussion (SRC) cases among student athletes that resulted in a relapse of their symptoms due to premature return to play (RTP) or premature return to learn (RTL) has changed compared with a prior (2006 to 2011) study. DESIGN: Retrospective cohort study of electronic medical record charts from a 5-year period (2011 to 2016) compared with previous data. SETTING: A sport and exercise medicine physician's office-based practice in Ontario. PARTICIPANTS: Two-hundred forty-one students who had 258 distinct cases of SRC diagnosed. MAIN OUTCOME MEASURES: Premature RTP and RTL were defined as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient's RTP or RTL. RESULTS: Between 2011 and 2016, premature RTP and RTL resulted in a relapse of symptoms in 26.7% and 42.6% of cases, respectively. When compared with data from the 2006 to 2011 chart review, the incidence of premature RTP decreased by 38.6%. However, the rate of the relapse of symptoms associated with premature RTL decreased by only 4.7%. There was a relapse of symptoms in 43.4% of the cases involving female students and 29.7% of the cases involving male students, indicating that female patients are more likely to experience a relapse of symptoms. Cases involving female athletes also resulted in much later RTP clearance compared with those involving male athletes, with a median duration that was almost double that of male athletes' cases (49 days vs 25 days). CONCLUSION: An important decrease in the relapse of symptoms in the context of premature RTP occurred over the 2006 to 2016 period. However, this decrease was minimal for RTL. This may reflect the fact that efforts to implement structured RTP strategies arose earlier than those to implement RTL strategies. Efforts are needed to find the best method of implementing a coordinated plan for the postconcussion athlete who is returning to school.

Androgen Effects on Neural Plasticity.

Androgens are synthesized in the brain, gonads, and adrenal glands, in both sexes, exerting physiologically important effects on the structure and function of the central nervous system. These effects may contribute to the incidence and progression of neurological disorders such as autism spectrum disorder, schizophrenia, and Alzheimer's disease, which occur at different rates in males and females. This review briefly summarizes the current state of knowledge with respect to the neuroplastic effects of androgens, with particular emphasis on the hippocampus, which has been the focus of much of the research in this field.
