EPILEPSY IN PATIENTS WITH ACUTEAND CHRONIC CEREBRAL ISCHEMIA

Abstract

Background. Epilepsy is one of the most common diseases of the nervous system. Cerebral
ischemia is an important risk factor for the development of seizures.
The purpose of the study: to study the clinical, MRI, functional and hemodynamic characteristics in
patients with cerebral ischemia with seizures.
Materials and methods: to achieve this goal a total of 772 patients suffering from acute and chronic
disorders of cerebral circulation (265 stroke patients and 174 patients with chronic cerebral ischemia
experienced epileptic seizures, 203 stroke patients and 130 patients with chronic cerebral ischemia
experienced no epileptic seizures) were under integral medical supervision. Patients in the control group
were matched with the study group in age, clinical characteristics, pathogenic subtypes of stroke and
stage of chronic cerebral ischemia.
Neurological examination was carried out by the usual method. Visualization of brain structures was
carried out with the help of magnetic resonance imaging (MRI) (1.5 Tesla). The functional state of the
cerebral hemispheres was assessed by electroencephalogram (EEG). In addition, the extracranial and
transcranial duplex sonography was performed.
Results: in patients with ischemic stroke and in patients with chronic cerebral ischemia focal
seizures prevailed, the highest rate of their development has been between the ages of 50 to 69 years.
Patients with seizures had a significant prevalence of symptoms caused by a violation of cerebral
circulation in vertebro-basilar basin. Focuses abnormal EEG activity prevailed in the temporal region
and in the left hemisphere of the brain. According to the MRI of the brain cortical and subcortical
ischemic lesions, increased cerebrospinal fluid spaces prevailed in patients with seizures. Stenoses of
major cerebral arteries were also more common in patients with seizures.
Conclusions. The study identified risk factors for epileptic seizures in patients with cerebral
ischemia.
