A hypoarousal model of neurological post‑COVID syndrome

The study “A Hypoarousal Model of Neurological Post-COVID Syndrome:the relation between mental fatigue, the level of central nervousactivation and cognitive processing speed” investigates the relationship between cognitive dysfunction, mental fatigue, and hypoarousal of the brain in post-COVID patients. Here’s a detailed summary: Background and Objectives: Post-COVID syndrome often includes neurological and neuropsychiatric sequelae, particularly cognitive dysfunction and fatigue. This study hypothesized that these symptoms in post-COVID syndrome are linked to hypoarousal of the brain. It aimed to assess whether tonic alertness, a neurocognitive index of arousal, is reduced in post-COVID patients and how this relates to central nervous activation and…
