Clinico-Electroencephalographic Studies on Epileptics With Spike and Slow Wave Complex Not Disappearing for 10 Years

With regard to variations in the spike and slow wave complex during 10 years, Hz increased among those in their 10s to 20s and showed a tendency to decrease from 40 years of age.

The duration showed unevenness. with some cases prolonged, others unchanged and still others shortened.

Many women in their 10s to 20s were found in the episodic symptom group. Hz showed a tendency to remain unchanged or else increased, while the duration tended to become shortened.

Episodic symptoms did not appear in primary tonic-clonic seizures but cases of intermittent psychiatric seizures became complicated with tonic-clonic seizures.

In the non-episodic symptom group, the spike and slow wave complex appeared evenly in each age decade; as to changes in Hz during 10 years, the increased or unchanged cases were overwhelmingly large; regarding changes in the duration, prolonged or unchanged cases accounted for the majority.
