Impairment of the Production of Delta Sleep in Anorectic Adolescents

Abstract: Sleep of anorectic patients seems to be characterized by an impairment of SWA-producing mechanisms independent of the increased sleep fragmentation. This is probably related to the primary pathophysiologic characteristics of the illness but could also reflect secondary functional and anatomic alterations of the brain.

“…Leptin has been postulated to play a role in cognition 113 and could accordingly also have implications for AN patients, among whom cognitive functions are particularly reduced in severely emaciated patients. AN patients show an increase of wakefulness after sleep onset, a higher number of arousals and a reduction of slow-wave sleep and slow-wave activity; 114 in ob/ob mice sleep regulation is altered. 115 Exogeneous application of leptin to leptin-deficient human adults was shown to have sustained effects on tissue composition in the human brain.…”

“…AN is characterised by both serious psychiatric symptoms and organic alterations in addition to functional and anatomic alterations in the brain of these patients (Nobili et al, 2004). The integrity of thalamocortical and cortical circuitry is essential for SWA production (Nobili et al, 2004).…”
