New Paper in Jour­nal of Sleep Research by Wein­hold et al.

In a col­lab­o­ra­tion with Sara Lena Wein­hold and Robert Göder at the Chris­t­ian-Albrechts-Uni­ver­si­ty Kiel, Hong-Viet V. Ngo recent­ly pub­lished a study inves­ti­gat­ing the influ­ence of audi­to­ry stim­u­la­tion dur­ing sleep on mem­o­ry con­sol­i­da­tion in peo­ple with schizophrenia.

The study shows that audi­to­ry stim­u­la­tion tar­get­ing slow oscil­la­tions – a key rhythm medi­at­ing mem­o­ry pro­cess­ing – in real-time in peo­ple with schiz­o­phre­nia results in an elec­tro­phys­i­o­log­i­cal response that is sim­i­lar to that in healthy par­tic­i­pants. Albeit an absent effect of stim­u­la­tion on mem­o­ry con­sol­i­da­tion, the authors found the stronger the slow oscil­la­tion enhance­ment the less par­tic­i­pants for­got, i.e., the bet­ter mem­o­ry per­for­mance was, the fol­low­ing morning.

Thus, this paper not only con­firms the over­all fea­si­bil­i­ty of this approach and pro­vides essen­tial elec­tro­phys­i­o­log­i­cal insights. It fur­ther­more high­lights the poten­tial of audi­to­ry stim­u­la­tion to pro­vide alter­na­tive treat­ments for sleep-relat­ed dys­func­tions in patients with schiz­o­phre­nia. The arti­cle will soon be avail­able in Jour­nal of Sleep Research.
