Introduction: Prolonged seizures cause cytotoxic edema and increase intracranial pressure. Optic nerve sheath diameter (ONSD) and its ratio to eyeball transverse diameter (ONSD/ETD) offer a noninvasive method for monitoring intracranial pressure changes. We calculated the ONSD and ONSD/ETD ratio of postictal children using computed tomography and evaluated the relationship between those values and seizure duration.

Article Synopsis
  • Researchers are studying how experiencing trauma, like during the COVID-19 pandemic, can lead to positive changes in people's emotions, known as posttraumatic growth (PTG).
  • In a study with 77 participants, those with high PTG showed different brain reactions when looking at negative and neutral pictures compared to those with low PTG.
  • The findings suggest that people with high PTG might handle emotions better by accepting feelings and not judging them, which leads to different patterns in their brain's responses.
