<qa>  What was the name of the medicine that eases mood problems in people without head injury?To treat the unmanageable mood, we tried a medicine called valproate, one that eases mood problems in people without head injury. We gave valproate to head injured persons with mood problems in a non-blinded study where both the doctor and the patient knew that the medicine was valproate and both were optimistic that it would work. In a small sample of eighteen people, 85 found mood relief and most of those either stopped drinking alcohol or drank much less than before. However, this might have been because both the doctor and patient were hopeful that the medication would make the patient feel better or because the medicine actually worked.
