Concussion is a mild traumatic brain injury, usually occurring after a blow to the head. Loss of consciousness isn’t required for a diagnosis. In fact, the risk of post-concussion syndrome does not appear to be associated with the severity of the initial injury. Symptoms such as noise sensitivity, problems with concentration and memory, irritability, depression, anxiety, fatigue, and poor judgment generally do not occur immediately after the injury, but rather days after. Post-concussion syndrome is usually not treated, though specific symptoms can be addressed. A mixture of medium THC and High CDB; is being used to treat the symptoms associated with PCS.
