Intranasal Dexmedetomidine-esketamine on Sleep and Cognition in Older Adults With Mild-to-moderate Cognitive Impairment
Abstract
Patients with cognitive decline are frequently comorbid with sleep disorders which may in turn aggravate cognitive decline. Sedative dose dexmedetomidine improved sleep quality but incresed bradycardia and hypotension; low dose dexmedetomidine produce less side effects, but the sleep promoting effects are relatively weak. Low dose esketamine also has sleep-promoting effects but may produce neuropsychiatric side effects. Both dexmedetomidine and esketamine are approved for intranasal administration. We suppose that intranasal administration of dexmedetomidine-esketamine combination may improve sleep quality and therefore cognitive function in older ptients with Alzheimer's disease cognitive impairment and sleep disorders.
