After a head or neck injury there is usually some headache together with symptoms of dizziness, sweating, cold feet and hands and memory loss, inconsistency of performance, lack of concentration, altered mood. This should not take more than half a year.
If a person undergoes a severe traumatic lesion of his brain he often will not get a headache. He might even lose it when he had one before his accident.
Usually, the more severe the actual brain injury, the less is the traumatic headache caused by it.

Diagnosis of Traumatic Headache
Depending on the location and the severeness of the head trauma ,will the patient complain of fatigue and weakness, his impaired capability to concentrate, his impaired performance, his often depressive or aggressive mood and - interestingly – an impaired alcohol tolerance. You may find aching muscles in the cervical and shoulder area.
Depending on location and severeness of the cerebral trauma focal alterations can be seen in the EEG. CT and MRI will show alterations in the cerebral tissue in case of cerebral contusion. Neuropsychological tests reveal and may prove the psychological disorders claimed by the patient.

Therapy for Traumatic Headache
The patient should have enough rest, he is not to be stressed by his job (although he should try to take up his work as soon as possible). In some aspects traumatic headache can be considered as tension headache so the same therapeutic principles may apply.
If muscular tension prevails (e.g. after a concussion together with a whiplash injury of the neck) physiotherapy should be applied. In the first stage a simple soft collar might help.
Certain anti–inflammatory medicines will be prescribed by your physician.
