Impaired brain function improved by l-carnitine in patients with cirrhosis: evaluation using near-infrared spectroscopy
To evaluate the effects of l -carnitine on impaired brain function in patients with liver cirrhosis. We conducted a retrospective cohort study that included sequential 80 liver cirrhosis patients with impaired brain function evaluated using near-infrared spectroscopy (NIRS). Among them, l -carnitine...
