Research progress on cognitive dysfunction and brain gray matter areas changes in patients with obstructive sleep apnea hypopnea syndrome / 中华神经科杂志

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a sleep breathing disorder caused by obstruction of the upper airway during sleep from various causes. At present, the diagnosis and treatment of OSAHS are insufficient. OSAHS causes cognitive decline due to excessive oxidative stress and inflammatory response caused by sleep breathing disorder, and its alteration of the brain gray matter area may be related to cognitive dysfunction. This review investigates the correlation between cognitive dysfunction and brain gray matter areas changes in OSAHS, and elucidates the underlying mechanisms, which provide a theoretical basis for early clinical diagnosis and treatment.
