ScienceDaily (May 6, 2008) — New guidelines developed by the American Academy of Neurology confirm that the drug botulinum toxin is safe and effective for treating cervical dystonia, a condition of involuntary head tilt or neck movement, spasticity and other forms of muscle overactivity that interfere with movement in adults and children with an upper motor neuron syndrome, and excessive sweating of the armpits and hands. Botulinum toxin may also be used in hemifacial spasm (involuntary facial contractions), blepharospasm, (involuntary eye closure), some voice disorders (adductor laryngeal dystonia), focal limb dystonias (such as writer’s cramp), essential tremor and some forms of spastic bladder disorders.
