Surgery is usually not necessary. Headache and dizziness are common, but if the headache persists or becomes severe, it is best to seek medical attention. Post-concussion syndrome may occur in some people. The syndrome generally consists of a persistent headache, dizziness, irritability, memory changes and vision changes. The person may seem overly emotional or unable to control their emotions.
Some people experience unexplained depression.
Difficulty with concentration or problems with thinking and planning ahead also are reported. Symptoms may begin weeks or even months after the initial injury. Although the symptoms generally resolve over time, some people need a rehabilitation specialist to oversee a program for recovery. It is important to keep in mind that recovery from a traumatic brain injury can be very slow. Sometimes several days can go by without seeing any major visible change.
