Older adults who had a concussion, and also received statins, had a slightly reduced risk for developing dementia later in life, according to findings recently published in JAMA Neurology.

“The role of statins in recovery after a concussion has rarely been investigated. ... On the one hand, the potential neuroprotective associations of statin use may prevent subsequent dysfunction by neuron preservation and neural stem cell activation. On the other hand, the neurohazardous associations of statin use might contribute to memory difficulties from altered neurophysiology,” Donald A. Redelmeier, MD, MSHSR of the department of medicine at the University of Toronto, and colleagues wrote.
