“Genetic testing for potentially lethal variants is more accessible than ever before and this document focuses on which athletes should be tested and when,” said author Dr. Michael Papadakis of St George’s, University of London, UK. “Sportspeople should be counselled on the potential outcomes prior to genetic testing since it could mean exclusion or restricted play,” The European Society of Cardiology (ESC) reported.
In most cases, clinical evaluation will dictate the need for preventive therapy such as a defibrillator and the advice on exercise and participation in competitive sports. Dr. Papadakis explained: “Even if a genetic abnormality is found, recommendations on treatment and return to play usually depend on how severe the disease is clinically. Is it causing symptoms such as fainting? Is the heart excessively weak or thick? Can we see many irregularities of the heart rhythm (arrhythmias) and do they get worse during exercise? If the answer is ‘yes’ to any of these questions then play is likely to be curtailed in some way.”
Despite my advanced years, with my family’s history of Alzheimer’s and dementia, I confess that anything that affects the brain gets my attention.
A new study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion. The research is published in the August 25, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The athletes participated in sports like football, volleyball and soccer.
“We know concussions may have long-term effects on the brain that last beyond getting a doctor’s clearance to return to play,” said study author Tom A. Schweizer, PhD, of St. Michael’s Hospital in Toronto, Canada. “It is unclear, however, to what extent the effects of repeated concussion can be detected among young, otherwise healthy adults. We found even though there was no difference in symptoms or the amount of recovery time, athletes with a history of concussion showed subtle and chronic changes in their brains.”
