Gov. Bill Haslam has proclaimed March as Brain Injury Awareness Month in Tennessee.
According to the state Health Department, about 8,000 people in Tennessee are admitted to the hospital each year with a traumatic brain injury.
The majority of traumatic brain injuries are concussions or other mild forms of brain injury from which people fully recover. But even a concussion can cause problems like headaches, sleep disruption, memory loss and depression.
Health Commissioner John Dreyzehner said in a news release that brain injuries can happen anywhere at any time, but many are preventable.
Safety measures include wearing a helmet while riding a bicycle or motorcycle or going skiing or snowboarding. He also cautions that even mild head injuries should be taken seriously.
