Abstract
We studied incidences of convulsive seizures in patients with cerebrovascular accidents, the lesion of which had originated in the cerebrum.
The results were as follows:
1) The incidences of immediate, early and late convulsions are 4.2%, 1.6% and 5.2%(7.5% in patients followed up for more than 2 years).
2) Occurrence of late seizures were adversely affected by
a) surgical procedures
b) hemorrhagic infarctions involving the cortex, and
c) immediate convulsions after infarction.
3) Patients with any kinds of operative procedures in both ischemic and hemorrhggic lesions showed a high tendency of late convulsions.
4) Most of late convulsions (92%) occurred within 2 years.
5) Presence of convulsions after cerebrovascular accidents did not have prognostic value for underlying brain diseases.
