Restless legs syndrome and drug-induced akathisia in headache patients.

The purpose of the research presented in this article was to characterize restless leg syndrome (RLS) in a headache population and correlate treatment induced risks with dopamine blockers. Fifty patients with severe headache who were admitted to an outpatient infusion center were enrolled. The diagnosis of RLS was established using the International Restless Leg Syndrome Study Group criteria. Patients were screened for baseline akathisia using an akathisia scale and reexamined for akathisia after receiving intravenous infusion with one of four dopamine receptor blocking agents as treatment for their headaches. A change from baseline to post-infusion assessment of two points on a global assessment of akathisia was considered positive for drug-induced akathisia. Our results indicated that 41 (82%) of patients had episodic or chronic migraine. The rest had new daily persistent headache, cluster, or posttraumatic headache. Seventeen subjects (34%) met the criteria for RLS. Nineteen (38%) of the subjects developed drug-induced akathisia. Thirteen (76.5%) of the subjects with RLS developed akathisia compared with only 6 of the 33 (18.2%) without RLS (P<.0001). Finally, we concluded that headache patients with RLS are at a greatly increased risk of developing drug-induced akathisia when treated with intravenous dopamine receptor blocking agents.

Modular headache theory: a new approach.

Many people experience headaches that do not fulfill the International Headache Society's criteria for a specific headache disorder, yet behave biologically like that disorder. Others fulfill criteria for one headache disorder but have features of another. To explain these observations, we propose that groups of neurons, called modules, become activated to produce each symptom of a primary headache disorder, and that each module is linked to other modules that together produce an individual's headache. Headaches develop phenotypic stability through a process referred to as learned stereotypy. This theory has implications for the classification, research, and treatment of primary and secondary headache patients.

Should butalbital-containing analgesics be banned? Yes.

In the United States analgesic-overuse headache is often caused by butalbital-containing analgesics. These agents can cause physical and psychological dependency, and dangerous withdrawal syndromes. Butalbital-containing analgesics have already been banned in several European countries. They are proven effective in tension-type headache, but not in migraine; there are many alternative treatments for migraine and tension-type headache. In the 20 years since analgesic overuse headache was widely recognized, butalbital overuse has remained distressingly common. It is time to ban these agents.

Hemiplegic cluster.

We report four cases of a new variant of cluster headache associated with hemiparesis. Clinical similarities with hemiplegic migraine suggest that hemiplegic cluster, too, may be a channelopathy. One of our patients had a family history suggestive of an autosomal dominant inheritance.

Olanzapine in the treatment of refractory migraine and chronic daily headache.

BACKGROUND: Olanzapine, a thienobenzodiazepine, is a new "atypical" antipsychotic drug. Olanzapine's pharmacologic properties suggest it would be effective for headaches, and its propensity for inducing acute extrapyramidal reactions or tardive dyskinesia is relatively low. We thus decided to assess the value of olanzapine in the treatment of chronic refractory headache. METHODS: We reviewed the records of 50 patients with refractory headache who were treated with olanzapine for at least 3 months. All previously had failed treatment with at least four preventative medications. The daily dose of olanzapine varied from 2.5 to 35 mg; most patients (n = 19) received 5 mg or 10 mg (n = 17) a day. RESULTS: Treatment resulted in a statistically significant decrease in headache days relative to baseline, from 27.5 +/- 4.9 before treatment to 21.1+/-10.7 after treatment (P <.001, Student t test). The difference in headache severity (0 to 10 scale) before treatment (8.7+/-1.6) and after treatment (2.2 +/- 2.1) was also statistically significant (P <.001). CONCLUSION: Olanzapine may be effective for patients with refractory headache, including those who have failed a number of other prophylactic agents. Olanzapine should receive particular consideration for patients with refractory headache who have mania, bipolar disorder, or psychotic depression or whose headaches previously responded to other neuroleptic medications.

Intravenous propofol in the treatment of refractory headache.

We analyzed the results of treating patients who had chronic daily headaches that were refractory to standard medications with repetitive low-dose boluses of intravenous propofol (2,6-diisopropylphenol). Patients were treated over a 1-year period at Thomas Jefferson University Hospital. A total of 18 patients were treated a total of 21 times. Over 90% of patients had at least some headache relief after treatment. The headache cycle was broken in eight patients. There were no complications. Intravenous propofol is safe and effective when used under monitored conditions and should be considered for patients who have refractory chronic daily headache and have failed other interventions.
