Reduzir a frequência das crises de cefaleia com melatonina

Estudo piloto para o tratamento de dores de cabeça com a melatonina. O objectivo do estudo, realizado pela Universidade de Atenas, foi avaliar a potencial eficácia da melatonina para a prevenção de cefaleia primária. Os resultados obtidos pela ingestão de 4 mg de melatonina, 30 minutos antes de deitar durante seis meses, foram significativos em que houve uma redução estatisticamente significativa na frequência de cefalea nos pacientes envolvidos no estudo.

There is growing evidence that headaches are connected to melatonin secretion. Our aim was to assess the potential effectiveness of melatonin for primary headache prevention. Forty-nine patients (37 with migraine and 12 with chronic tension-type headache, TTH) were prescribed oral melatonin, 4 mg, 30 minutes before bedtime for six months. Forty-one (83.6%) of the 49 patients completed the study, while eight dropped out for personal reasons. A statistically significant reduction in headache frequency was found between baseline and final follow-up after six months of treatment (p=0.033 for TTH patients and p<0.001 for migraineurs). The Headache Impact Test score was significantly reduced in both groups of headache patients (p=0.002 and p<0.001, respectively). At baseline, melatonin levels, measured both during a headache attack and a pain-free period, did not differ between patients with TTH and migraineurs (p=0.539 and p=0.693, respectively), and no statistically significant differences in Hamilton Depression Rating Scale scores were found between the two groups. Melatonin 4 mg as prophylactic therapy for primary headaches: a pilot study This pilot study shows promising results, in terms of headache frequency reduction and daily quality of life improvement, in both groups.
