Mark R Pressman

Sleep Med Rev 2018 Nov 10;43:92-95. Epub 2018 Nov 10.

Sleep Medicine Services, Lankenau Medical Center, Wynnewood, PA, USA; Lankenau Institute for Medical Research, Wynnewood, PA, USA; Department of Medicine, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, PA, USA; Charles Widger School of Law, Villanova University, Villanova, PA, USA. Electronic address:

The DSM-5 and ICSD-3 have removed alcohol from the list of potential triggers for sleepwalking due to the lack of empirical evidence. Recent imaging and EEG based studies of sleepwalking and confusional arousals have provided a more data-based method of examining if alcohol is compatible with what is known about the neurophysiology and neurochemistry of sleepwalking. These studies have demonstrated a deactivation of the frontal areas of the brain, while the cingulate or motor cortex remains active and characterized activation in the form of beta EEG. Read More
