We studied serial median nerve somatosensory evoked potentials (SEPs) and short latency somatosensory evoked potentials (SSEPs) in 17 patients with West syndrome. Four of the 7 patients with absent SEPs in the initial examination showed recognizable SEPs in the follow-up studies. associated with improvement of electroencephalogram (EEG). This indicated that SEPs were variable with condition of epilepsy and lack of initial SEPs was not always a poor prognostic factor for seizure control and developmental outcome. Persistent lack of SEPs, however, indicated poor outcome of seizures, EEG and development. Central conduction time in SSEPs did not correlate with seizure or developmental outcome.
