Insights
Parietal spikes in children, initially triggered by touch, may evolve into epilepsy. A 3-year study found 16% of children developed seizures, suggesting a potential link to parietal cortical hyperexcitability.
Area of Science:
- Pediatric neurology
- Neurophysiology
Context:
- Children can exhibit parietal spikes triggered by tactile stimulation.
- The long-term evolution of this phenomenon is not well understood.
Purpose:
- To investigate the natural history of tactile-evoked parietal spikes in children.
- To determine if this phenomenon progresses towards epilepsy.
Summary:
- 36% of children with normal initial EEGs developed spontaneous spike foci.
- Over 3 years, 16% of subjects experienced seizures.
- Findings suggest a potential hyperexcitability in a small parietal cortical area.
Impact:
- Highlights the potential for pediatric parietal spikes to indicate an evolving epileptic condition.
- Suggests early identification and monitoring may be crucial for at-risk children.
- Provides insight into the neurophysiological basis of certain childhood neurological phenomena.
Abstract:
It is known that some children produce parietal spikes, evoked by tactile stimulation to their feet or other parts of their bodies. This paper investigates whether this curious phenomenon remains with the children unchanged for several years and then disappears or whether it has an evolution towards epilepsy. It has been found that 36% of the subjects, who showed a normal EEG in the first examination, developed a spontaneous focus of spikes during their sleep or waking period; during a period of up to 3 years 16% of the children present a clinical state represented by seizures. In conclusion, it is felt that the cause of this condition may be due to hyperexcitability of a small cortical parietal area.
