Traumatic Brain Injury (TBI) & Stroke

Strokes occur when a part of the brain has inadequate blood flow, either from a blockage of a blood vessel (ischemic) or bleeding directly onto the brain or the space in between the brain’s membranes (hemorrhagic), eventually resulting in brain cell death. An inability to feel or move on one side of the body, a loss of vision to one side, migraine, problems understanding or speaking and a “spinning” feeling are all signs of a stroke. High blood pressure is a big risk factor in suffering a stroke. Obesity, tobacco smoking, high blood cholesterol, diabetes, a previous traumatic brain injury (TBI) and atrial fibrillation are all also risk factors for a stroke.

There is a lot of mixed evidence on cannabis and strokes, although there may be more help in cannabis for those who have TBIs from sports injuries. There are several studies that show a correlation between the use of cannabis and the likelihood of a stroke; but, as they say, correlation does not necessarily mean causation, and there are many factors to account for, including diet, tobacco smoking and previous TBIs. There is also a not-insignificant amount of scientific research into the use of cannabinoids to treat TBIs, as cannabinoids such as CBD may help protect the brain from neuroinflammation. There are several cannabinoids, including THC and CBD, that may help prevent dangerous amounts of glutamate forming, which can actually potentially prevent strokes.
