Impaired release of corticosterone from adrenals contributes to impairment of circadian rhythms of activity in hyperammonemic rats.

Patients with liver cirrhosis may present impaired sleep-wake and circadian rhythms, relative adrenal insufficiency and altered hypothalamus-pituitary-adrenal gland (HPA) axis. The underlying mechanisms remain unclear. Circadian rhythms are modulated by corticosteroids which secretion is regulated by HPA axis. Hyperammonemia alters circadian rhythms of… CONTINUE READING
