Central pain as a manifestation of partial epileptic seizures.

Central pain of epileptic etiology is very rare. The frequency of painful sensations in epileptic seizures varies between 0.3 and 2.8%. We report a patient with short-lasting painful attacks in the right arm. Changes in the electroencephalography (EEG) and the effective treatment with anticonvulsants in contrast to the therapeutic failure of analgesics, lead to the diagnosis of partial epilepsy with painful seizures. Magnetic resonance imaging (MRI) of the brain was normal, whereas a postcentral parietal site of seizure origin involving the secondary somatosensory area was suggested by electroencephalographic findings. The literature is reviewed for cases with pain as the sole or predominant symptom of epileptic seizures.
