[Early somatosensory evoked potentials in ischemic diseases--II: Normal values and findings in asymptomatic vascular stenoses/occlusions, complicated migraine, transitory ischemic attacks, reversible ischemic neurologic deficit, complete stroke and multi-infarct dementia].
Somatosensory evoked potentials (SEP) were investigated in 140 patients suffering from cerebro-vascular ischemic disease (CVD). Data were compared to age-correlated normal persons (n = 26; male 16, mean age 55.6 years SD 10.9). Patients with asymptomatic vascular diseases (n = 10; male 7, mean age 63.8 years SD 10.4) showed bilateral prolonged CCT (left side p less than 0.05). Patients with TIA (n = 44; male 21, 58.3 years SD 12.3), complicated migraine (n = 3, all female, 24, 40, 63 years) and RIND (n = 17; male 10, 56.5 years SD 16.8) showed no abnormalities of CCT and AR as compared to normals. Abnormalities of PHAS were only seen in patients with RIND of the right carotic supply. In patients suffering from completed stroke (n = 40; male 29, mean age 56.9 years SD 14.4) bilateral prolongation of CCT was seen in those with ischemia of the right carotic supply; those with ischemia of the left carotic supply showed a significant asymmetry of CCT and deviation of AR l/r. In two patients with infarction of the pons an increase of CCT and decrease of AR at the side of the lesion was found. Patients with MID (n = 27; male 20, 69.7 years SD 10.3) showed significant bilateral prolongation of CCT, increase of AR (at the side of stimulation) and deviation of AR l/r (1.63).
