Botulinum neurotoxin type-A for primary stabbing headache: an open study

Toxina botulínica do tipo-A para o tratamento da cefaléia primária em punhaladas: um estudo aberto

Primary stabbing headache is an ultra-short headache, associated with primary headaches, more prevalent in women and with a poor response to therapy. The effect of botulinum neurotoxin type-A (BoNTA) on primary stabbing headache was investigated in 24 patients. Three patients showed complete remission. Nineteen patients showed a decrease in their primary stabbing headaches that started in the second week, and that was sustained during approximately 63 days. In two patients BoNTA showed no therapeutic effect. The BoNTA seems to be an excellent therapeutic option for primary stabbing headache.
