March is Brain Injury Awareness Month to increase awareness about traumatic brain injury or TBI. A TBI can occur after a blow, jolt or hit to the head and range in severity from mild to penetrative. Blanchfield Army Community Hospital Neurologist Maj. Michael Johnson explains the symptoms to look for.

"The most important thing is awareness of concussion symptoms which can include headache, difficulty with memory, difficulty with sleep and difficulty with balance," said Johnson. He recommends following up with your primary care provider if you experience those symptoms in the days following a head injury.

Johnson said the most common form of brain injury is a concussion and can occur on duty, during training exercises, and even at home.
