Glymphatic transport disruption has been suggested as one potential mechanistic link. However, evidence across sleep disorders and glymphatic-related metrics remains fragmented. We aimed to determine whether glymphatic-related metrics are altered in OSA, SD, and NT1. We performed a systematic review and meta-analysis of clinical and preclinical studies to determine whether glymphatic-related metrics are altered in OSA, SD, and NT1. Across studies of OSA, glymphatic-related metrics indicated si","pubDate":"2026-10-22","url":"https://www.medrxiv.org/content/10.64898/2026.10.20.26366043v1?rss=1"},"indexado":"2026-10-22T21:54:18.823Z"}}
