Popis: Methods 23 comatose patients investigated. Vegetative state (VS) and minimally conscious state (MCS) diagnosed. Patients assessed by GCS. Coma recovered patients-by Disability Rating Scale (DRS). Etiologically coma was divided in 5 groups. Statistical analysis performed by SPSS 11.0. Results Among 23 VS-patients 9 evaluated as MCS. In 1st group From 6 VS-patients (GCS = 5) with theta EEG pattern 2 were defined as MCS, at 1 year 1 recovered (DRS = 14), 1 died. 4 patients defined at 1 year as PVS. 2nd group: 3 VS-patients (GCS = 5–7) with beta EEG pattern. 2 developed PVS, 1 MCS (recovered DRS18). 3rd group: 2 VS-patients with alpha EEG pattern (GCS = 6) died. 4th group: 4 VS-patients (GCS = 5–7) with delta EEG pattern 2 defined as MCS. At 1 year 1 died and 3 developed PVS. 5th group: from 8 VS-patients (GCS = 5–8) 4 diagnosed as MCS, 4 with delta EEG patterns and 4 with theta EEG patterns. 4 VS-patients remained with delta EEG pattern. At 1 year 1 patient with MCS recovered (DRS = 11), 2 with MCS and 3 with VS died, 2 patients developed PVS. Correspondence analysis revealed that sound localization (Chi-sqr. = 31.10493; p = 0.000001) is significantly associated with EEG theta rhythm and with outcome. Conclusion High amplitude theta frequencies in VS patients where significant for favorable outcome.
