Headache after Trauma
Head | Neurology | Headache after Trauma (Symptom)
Headache immediately following a head injury usually clears after minutes or days but sometimes headaches may persist for months or rarely years. The long-term headaches are called post-traumatic or post-concussion headaches. Mild injuries of the brain are characterized as a concussion (a brief disturbance of brain function causing loss of consciousness or transient difficulty in thought processes).
The clinical features of post traumatic headache may vary from one individual to another. Most headaches would be now classified as chronic tension-type headache. These headaches are typically a steady ache affecting both sides of the head and occurring daily or almost everyday. They are of slight to moderate intensity but intermittently, upon this base of low grade headache bouts of severe or moderately severe headache may occur and these often are similar to, if not identical with migraine (one sided throbbing pain associated with nausea and sensitivity to light and noise).
Unfortunately, people who experience post traumatic headaches also experience other symptoms of the post-traumatic or post-concussion syndrome. There may be other neurological symptoms such as dizziness, ringing in the ears, vague blurring of vision, psychological symptoms occur such as depression, anxiety, personality change, disturbance in sleep, and impairment libido.
Finally, people with the post-concussion syndrome have changes in their mental functioning, primarily difficulty in concentration, inability to work efficiently and associated difficulty maintaining attention and retaining memory.
