WebMar 22, 2024 · Hypoxic brain injury can occur due to respiratory depression, a serious consequence of opioid overdose. 19 In addition to being a particular risk with opioids (such as heroin, OxyContin or fentanyl), use of benzodiazepines, alcohol, or other sedatives can also lead to respiratory depression. WebConclusions: Older adults with severe nocturnal hypoxemia demonstrate impaired functional connectivity in medial temporal structures, key regions involved in sleep memory processing and implicated in dementia pathophysiology. Oxygen desaturation and functional connectivity in these individuals each relate to cognitive performance.
