The American Academy of Neurology has updated its 2008 guidelines on using botulinum toxin for brain disorders.
One of the main changes: Botulinum toxin A is now recommended for the management of chronic migraine, defined as attacks lasting 4 or more hours on at least 15 days each month for 3 months. Previously, there wasn't enough evidence for this recommendation, but new placebo-controlled studies show a small, 15% reduction in the number of headache days with treatment. Botulinum toxin A is not recommended for less frequent, "episodic" migraine.
In addition, the guidance states that botulinum toxin is generally safe and effective for treating spasticity in adults, cervical dystonia, and blepharospasm.
