Palinopsia: An Overlooked Symptom in Epilepsy Care

Source: Clinical EEG and neuroscience

Summary

This study focused on a 58-year-old man who developed a specific type of seizure called palinopsia after a brain injury. Palinopsia is when a person continues to see images or visual experiences even after they should have stopped. The researchers also reviewed other cases of palinopsia in people with epilepsy to understand its features and treatment better.

The key findings showed that the man's seizures included visual disturbances followed by more severe convulsions. After being treated with a medication called lamotrigine, he experienced a significant reduction in his symptoms over 20 months. The review of other cases found that many people with palinopsia had abnormal brain activity seen on EEG tests, especially in the right side of the brain, and that structural issues like tumors were common causes.

This research is important because it highlights palinopsia as a symptom that may not be recognized enough in people with epilepsy. Understanding the brain activity patterns associated with palinopsia can help doctors diagnose and treat it more effectively. However, the study has limitations, such as a small number of cases reviewed and the need for more research to confirm these findings and improve treatment options.
