SURGICAL TREATMENT OF EPILEPSY

Abstract

|
|
Unfortunately, few experimental studies of the preoccipital area are on record.
From clinical observation it is likely that the preoccipital areas are concerned primarly with visual
associations involving the other sensory and motor areas of the cortex.
The preoccipital area receives impulses from all parts of the cortex and it thus serves as a center
for coordinating visual with other reflexes.
Fifty-one cases of intractable epilepsy were treated by the preoccipital coagulation in the treatment. An interesting fact was noted in serial electroencephalographic studies of the cases in the progressive
normalization of the record in months and years after preoccipital coagulation, and this change had
no relation with any medical anticonvulsive therapy.
There has also been a great improvement in the electroencephalographs, and spikes and abnormal discharges have disappeared or greatly diminished.
The author performed on 51 cases of intractable epilepsy to determine the effects of procainization on the electrical activity of the cerebral cortex.
Electrocorticograms were obtained from both the preoccipital and fronto-parietal area electrodes. Analysis of cortical electro grams following procainization is summarized as follows: 1. Procainization of the preoccipital area leads to suppression to the same hemisphere. 2. Procainization of the fronto-parietal area leads to no suppression to the preoccipital area.
3. Preoccipital procainization leads to a suppression of the electrical activity of the cortex which
spreads slowly over the ipsilateral cerebral cortex.
4. Preoccipital coagulation in the treatment of epilepsy leads to suppression to all the parts of the cerebral cortex.
