Migraine attacks are often preceded by premonitory symptoms. Prevalence rates of migraine patients reporting one or more premonitory symptoms show considerable variability and rates range between 12% and 79%. Sources of variability might be differences in study population or research design. ⋯ Age, education, migraine subtype (with or without aura) and mean attack frequency had no effect on the mean number of symptoms per individual. In conclusion, premonitory symptoms are frequently reported by migraine patients. Sensitivity and specificity of premonitory symptoms for migraine need to be assessed using prospective methods.

Randomized Controlled Trial
Advice alone vs. structured detoxification programmes for medication overuse headache: a prospective, randomized, open-label trial in transformed migraine patients with low medical needs.
The aim of this study was to compare the effectiveness of strong advice to withdraw the overused medication with the effectiveness of two structured pharmacological detoxification strategies in a cohort of patients diagnosed with probable migraine overuse headache (MOH) plus migraine and presenting low medical needs. One hundred and twenty patients participated in the study. Exclusion criteria included: previous detoxification treatments, coexistent medical or psychiatric illnesses and overuse of agents containing opioids, benzodiazepines and barbiturates. ⋯ Withdrawal therapy was considered successful if, after 2 months, the patient had reverted to an episodic pattern of headache and to an intake of symptomatic medication on fewer than 10 days/month. We were able to detoxify 75.4% of the whole cohort, 77.5% of patients in group A, 71.7% of patients in group B and 76.9% of those in group C (P>0.05). In patients with migraine plus MOH and low medical needs, effective drug withdrawal may be obtained through the imparting of advice alone.

Controlled Clinical Trial
Myofascial trigger points, neck mobility and forward head posture in unilateral migraine.
This paper describes the differences in the presence of myofascial trigger points (TrPs) in the upper trapezius, sternocleidomastoid, temporalis and suboccipital muscles between unilateral migraine subjects and healthy controls, and the differences in the presence of TrPs between the symptomatic side and the non-symptomatic side in migraine subjects. In addition, we assess the differences in the presence of both forward head posture (FHP) and active neck mobility between migraine subjects and healthy controls and the relationship between FHP and neck mobility. Twenty subjects with unilateral migraine without side-shift and 20 matched controls participated. ⋯ However, there was a positive correlation between the cranio-vertebral angle and neck mobility. Nociceptive inputs from TrPs in head and neck muscles may produce continuous afferent bombardment of the trigeminal nerve nucleus caudalis and, thence, activation of the trigeminovascular system. Active TrPs located ipsilateral to migraine headaches might be a contributing factor in the initiation or perpetuation of migraine.

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.
