Cephalalgia : an international journal of headache

We describe two adults with stroke-like migraine attacks after radiation therapy (SMART syndrome), propose revised diagnostic criteria, and review the previously reported patients. 'SMART' is an acronym for a newly recognized syndrome which occurs as a delayed consequence of cerebral irradiation and consists of prolonged, unilateral, migrainous neurological symptoms with transient, dramatic cortical gadolinium enhancement of the affected cerebral hemisphere and is sometimes punctuated by generalized seizures and ipsilateral EEG slowing. Although the neurological symptoms can last for weeks, full recovery occurs. An appropriate evaluation should exclude alternative explanations.

A 45-year-old woman, who had been diagnosed in our unit with episodic paroxysmal hemicrania, was seen 2 years later for ipsilateral hemicrania continua in remitting form. Both types of headache had a complete response to indomethacin and did not occur simultaneously. The patient had a previous history of episodic moderate headaches that met criteria for probable migraine without aura and also had a family history of headache. The clinical course in this case suggests a pathogenic relationship between both types of primary headache.

Controlled Clinical Trial
Generalized hyperalgesia in patients with chronic tension-type headache.
Increased pain sensitivity in the central nervous system may play an important role in the pathophysiology of chronic tension-type headache (CTTH). Previous studies using pain thresholds as a measure of central pain sensitivity have yielded inconsistent results and only a few studies have examined perception of muscle pain without involvement of adjacent tissues. It has been suggested that suprathreshold testing might be more sensitive than threshold measurements in evaluation of central hyperexcitability in CTTH. ⋯ The degree of temporal summation of muscular and cutaneous pain tended to be higher in patients than in controls but the differences were not statistically different. This study provides evidence for generalized increased pain sensitivity in CTTH and strongly suggests that pain processing in the central nervous system is abnormal in this disorder. Furthermore, it indicates that suprathreshold stimulation is more sensitive than recording of pain thresholds for evaluation of generalized pain perception.

Randomized Controlled Trial Multicenter Study
Efficacy of physiotherapy including a craniocervical training programme for tension-type headache; a randomized clinical trial.
We conducted a multicentre, randomized controlled trial with blinded outcome assessment. The treatment period was 6 weeks with follow-up assessment immediately thereafter and after 6 months. The objective was to determine the effectiveness of a craniocervical training programme combined with physiotherapy for tension-type headache. ⋯ Effect sizes were large and clinically relevant. Loss to follow-up amounted to 3.7%. Physiotherapy including craniocervical training reduces symptoms of tension-type headache significantly over a prolonged time frame.

The aim of this large, cross-sectional, population-based study was to examine the association between sick leave and headache. Between 1995 and 1997, all 92 566 adults in Nord-Trøndelag County in Norway were invited to participate in a health survey. Out of 73 327 invited individuals <67 years old, a total of 38 192 (52%) responded to questions about headache, work situation and sick leave during the past year. ⋯ There was an increasing prevalence of sick leave with increasing frequency of migraine and non-migrainous headache. The prevalence of sick leave >8 weeks during the past year was more than three times higher among individuals with headache >14 days per month (20%) compared with those without headache (6%). The results may indicate that better treatment of individuals with chronic headache may have beneficial economic implications.
