P37-T Clinical neurophysiological examination as a prognostic tool in evaluating outcome in intracerebral haemorrhage

Abstract

Background We examined whether electroencephalography (EEG) and magnetic evoked potential (MEP) examinations are useful in evaluating the early prognosis in a fatal disease, intracranial haemorrhage (ICH). Material and methods Fifty-seven patients were diagnosed with ICH with cranial CT (blood and oedema volume). Clinical status, by 47 patients EEG and by 42 patients MEP was done on admission, at 14\u202fdays and at 3\u202fmonths. Results The bleeding localisation was as follows: 37 basal ganglia, 6 thalamus, 4 lobar. The 14-days-MEP showed progression in most of the patients, and deterioration was severe in those who died. At 3\u202fmonths 15 patients had MEP and 10 improved. The measured blood volume on the first CT was significantly associated with the 3-months-MEP findings (p\u202f The MEP amplitudes had a better prognostic value than the latencies. The changing of the MEP parameters were more pronounced in case of distal registration by cortical stimulation than proximally. On EEG, despite unihemispheric bleeding, 22% in the basal ganglia group had bilateral cortical dysfunction and bilateral (later improvement) MEP abnormality distally. From the basal ganglia group 13.5 %, the thalamus group 66.7% had no abnormality on EEG. Epileptiform discharges were detected in 17% of the patients within 14\u202fdays only from the basal ganglia group. Conclusion With EEG and MEP examinations early prognosis of functional outcome could be estimated in ICH patients. For bilateral functional disturbance in many patients diaschisis effect could be responsible. GINOP-2.3.2-15-2016-00043.
