Doctor's Notes on Concussion
Concussion refers to a mild traumatic brain injury that causes functional changes in brain function but does not lead to structural damage to the brain. The loss of function is short-lived and goes away on its own. Trauma to the head from any cause, such as an accident or sports injury, is the cause of a concussion.
Symptoms of a concussion may be severe or very subtle and hard to describe, even by the affected person. These may include:
- loss of consciousness,
- mild confusion,
- slowing of reaction times, and
- difficult concentrating or feeling that one’s thoughts are “foggy.”
Other associated symptoms and signs may include:
- changes in sleep pattern (either being unable to sleep or excessive sleep), and
- reduced tolerance of bright lights or loud sounds.
What Is the Treatment for Concussion?
Rest or limiting activities that require mental focus or concentration is the initial treatment for concussion in the first 48 hours after the injury. Daily activities may be increased gradually during recovery.
It is recommended not to engage in vigorous physical activity while recovering, although some light activity may be recommended. It is also important to avoid activity that could result in another head injury.

Basic first aid may be all that is necessary for more minor wounds. Infection is the biggest medical concern when it comes to cuts or lacerations. Signs of infection include severe pain, draining pus, redness beyond the wound edges, fever and chills, and excessive wound swelling.
