ABSTRACT
Intractable epilepsy with painful partial motor seizures is a relatively rare and difficult disorder to treat. We evaluated the usefulness of botulinum toxin to reduce ictal pain. Two patients received two or four botulinum toxin (BTX) injections at one-to-two-month intervals. Patient 1 had painful seizures of the right arm and hand. Patient 2 had painful seizures involving the left foot and leg. Injections were discontinued after improved seizure control following resective surgery. Both patients received significant pain relief from the injections with analgesia lasting at least two months. Seizure severity was reduced, but seizure frequency and duration were unaffected. For these patients, BTX was effective in temporarily relieving pain associated with muscle contraction in simple partial motor seizures. Our findings do not support the hypothesis that modulation of motor end-organ feedback affects focal seizure generation. BTX is a safe and reversible treatment that should be considered as part of adjunctive therapy after failure to achieve control of painful partial motor seizures.

Humans spend approximately one third of their lives asleep. Although the same medical disorders that occur during wakefulness persist into sleep, there are many disorders that occur exclusively during sleep or are manifestations of a disturbance of normal sleep-wake physiology. The most common reason for referral to a sleep laboratory is OSA, whereas the most common sleep disorder is insomnia. Effective treatments now exist for many sleep disorders, such as OSA and RLS, and a major breakthrough in the treatment of narcolepsy seems imminent. Because all disease processes are adversely affected by insufficient sleep, it is essential that the practicing physician understand the causes and treatments of the common sleep disorders.
