Naratriptan for the Treatment of Post Traumatic Headache Associated With Cognitive Dysfunction

Post Traumatic Headache Clinical Trial

Official title: Evaluation of the Efficacy of Naratriptan for the Treatment and Prevention of Post Traumatic Headache Associated With Cognitive Dysfunction

Status Terminated

Clinical Trial Summary

The purpose of this study is to determine whether naratriptan, a medication approved for treatment of migraine, is effective in the treatment of post traumatic headache associated with cognitive dysfunction.

Clinical Trial Description

Naratriptan has demonstrated efficacy in relieving headache. Other studies have demonstrated that primary headaches with at least one headache feature are likely to respond to triptans. In addition, there are anecdotal reports of triptans being effective in post traumatic headaches, especially if headache features are noted in the patient's history. Further, there are several small pilot studies with triptans demonstrating a prompt improvement in headache-induced cognitive changes. Cognitive performance can be measured by the Mental Efficiency Workload Test (MEWT), a handheld Palm neuropsychological test battery that measures mental efficiency. This tool can be used to demonstrate short and long term improvement in mental status beyond that seen at baseline.

Informal observations by the protocol authors have suggested that the use of triptans on a routine basis may ameliorate the headache and associated symptomatology of post traumatic headache. Therefore, this study is undertaken to study the use of naratriptan in the treatment of post traumatic headache. Roger K. Cady, MD, serves as the sponsor. The study is funded by GlaxoSmithKline.

56 subjects with a formal diagnosis of Chronic post-traumatic headache attributed to mild head injury (IHS/ICHD-II 5.2.2) and with self-reported mild cognitive inefficiency secondary to headache will be enrolled. Subjects meeting inclusion criteria will complete a physical examination and baseline testing and be randomized 1:1 to naratriptan 2.5mg bid x 30 days or a matched placebo bid x 30 days. A daily diary will document response to treatment. Subjects will return to the clinic at Day 10 and Day 30 and complete phone contacts at Days 5, 15, 21, 32 and 90. Information will be collected throughout the study on questionnaires related to headache impact, general health, satisfaction with medication, and quality of life. Cognition will be measured using the MEWT. ;
