During the past several years, public awareness about brain injuries has increased — thanks in part to several former professional athletes, military veterans, and accident survivors who are speaking out about effects of brain injuries, as well as a variety of brain injury awareness campaigns conducted by athletic and government organizations.
Researchers also have been conducting studies to learn more about brain injuries, so they can understand the causes and develop new, more effective treatments. One brain injury treatment that is showing promise is cannabidiol, or CBD, which is a non-intoxicating cannabinoid molecule produced by cannabis.
WHAT IS A BRAIN INJURY?
Traumatic brain injury (TBI) is a condition that occurs when a head injury, such as a bump, blow, or jolt, causes your brain to slam into the inside of your skull, which results in brain damage.
When your brain is injured, it releases neurotransmitters and chemicals that cause inflammation, blood vessel injury, chemical imbalances, tissue damage, and cell death. These brain responses are called a “secondary injury cascade” and are responsible for many of the neurological problems associated with TBI.
Although a severe TBI can be deadly or cause lifelong complications, even a mild TBI — which is commonly called a concussion — can cause symptoms that can last for days or weeks.
Repeated TBIs can cause a buildup of Tau protein, which can lead to a degenerative neurological condition called chronic traumatic encephalopathy (CTE). CTE can have a devastating impact on individuals and their families because it can cause a variety of symptoms that affect memory, emotions, behavior, movement, and mental functioning.
