[Changes in evoked potentials caused in patients with acute stroke (based on literature review 1988-1999].
The CNS neuron excitability and plasticity are objective and measured on the basis of the somatosensory (SEP) and motor (MEP) evoked potential (EP) findings. The EP examinations are performed in acute stroke (ac-sk) and comatose patients (pts) after brain injury. It was tried to check publication frequency of the reports in the 1988-1999 years, in Neurologia i Neurochirurgia Polska and in the journals registered in the MEDLINE system. The screening meta-analysis was conducted of the reported findings. The authors of 23 publications from 16 countries performed SEP and/or MEP examinations in the 802 ischeamic and 140 haemorrhagic acute stroke patients. The lesion was accurately localized, the immediate and late plasticity was identified and the influence of mannitol on penumbra neurons was assessed. The time of active movement recovery and the functional improvement of the patients were early and accurately prognosticated.
