Abstract:
The study included 22 patients with poststroke epilepsy (group 1) and 30 patients with stroke without epilepsy (group 2). A bilateral decrease of the time of central conduction (TCC) through pyramidal path (both on the paretic and intact side) was revealed in group 1. This was not observed in patients of group 2 with similar gravity of motor disorders (p < 0.01). Tendency to TCC decrease was also observed in patients without epileptic disorders by day 5-6 after ischemic stroke. However, TCC values were increased in such patients by day 10-14. Low indices persisted for a long time in patients with poststroke. There was also an increase of delta index of facilitation (the difference between TCC in rest and in muscle effort). It was also found that motor disorders in the group of patients with poststroke epilepsy were characterised by higher muscular tone than in poststroke patients with the same degree of the paresis.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Epilepsy and Seizures: Overview
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
