Patients with writer’s cramp face severe handicap and disability in their jobs or education, as they are unable to write properly. A diagnosis of writer’s cramp can be made on the basis of history and careful clinical examination.
Writer’s cramp can be well managed by medications such as trihexiphenidyl, tetrabenazine or clonazepam. Botulinum toxin is the most effective treatment for writer’s cramp.
