Aim: Sudden neurologic states of various aetiology are the major reason for medical teams to be dispatched and often result in hospitalization of the patient. The purpose of this work was the analysis of the aforementioned neurologic states and pinpointing the type of patients the Emergency Medical Service teams have encountered in Rybnik with respect to the said states. Method: Analysed material consisted of Medical Emergency Action cards that were used by Emergency Medical Service Independent Public Healthcare District Hospital No. 3 in Rybnik in the year 2013. Five hundred and twenty-three cases were selected as consistent with sudden neurologic states. Result: A higher incidence of studied diseases was noted among male patients, whereas in females presenting with these states, the age was higher, with the exception of syncope. The analysis revealed the presence of characteristic symptoms in relevant emergency conditions. During the evaluation of psychomotor abilities, a prevalence of patients whose state qualified as normal, and in the case of stroke as “slowed down” was recorded. Brain damage in all states except for stroke was classified as mild. The study noted high blood glucose level disparities between measurements. Conclusion: Strokes occurred most often in patients over 60 years old. The observed signs were consistent with those described in the literature. Blood glucose test results in some patients allowed suspicion of diabetes, or ruled out hypoglycaemia. The majority of studied patients revealed mild brain injury. Alcohol had a significant effect on the incidence of head injuries and seizures.
