What to watch with APOE and Sport?

APOE (Apolipoprotein E) is a gene primarily known for lipid metabolism and Alzheimer's risk. In sports, evidence suggests that carriers of the ε4 variant may have an increased risk of worse outcomes after traumatic brain injury (e.g., concussions). Studies indicate ε4 is associated with poorer cognitive recovery and possibly higher susceptibility to chronic traumatic encephalopathy (CTE). However, the evidence is moderate and not definitive – many factors like training intensity, protective gear, and individual genetics play a role. A genetic test for APOE alone is not diagnostic; it can only create additional risk awareness. If you are active in contact sports, you should inform yourself about protective measures and seek medical advice after repeated head injuries. MyBody-X offers APOE tests, but interpretation should always be done by a professional. Beware of exaggerated marketing claims: an APOE result says nothing about current athletic performance or individual injury risk.
