Forensic Sleep Medicine and
Scientific Evidence
Prosecution &Defense Consultation/Expert Testimony

Sleepwalking may appear amusing, but it and similar disorders can result in serious injury and even death. Sleepwalking is not just "walking" but can include complex behaviors including eating, sex and violence. For this reason, sleepwalking behaviors are sometimes presented as a defense for acts - murder, assault, rape -that would be otherwise criminal.
This defense may have a basis in reliable science or not. It may be a last ditch, "junk science" defense for a criminal act for which the defendant has no excuse. Or it may be a bone fide automatism defense.
When the defense for criminal acts is a claim that they were performed without conscious awareness or without criminal intent due to a sleep disorder, experts in sleep and sleep disorders are often retained by one or both sides. This area of science has become highly specialized with dozens of new research articles appearing every year. As a result, a small number of sleep experts have specialized in sleepwalking and related disorders. An even smaller number have specialized in forensic aspects of sleep disorders. Mark R. Pressman, Ph.D. is one of these highly specialized Forensic Sleep Experts.
Additional services include evaluation of defense and prosecution witnesses to determine if their reports and testimony are based on reliable and up-to-date science. Assistance with Frye or Daubert hearings. Vetting of expert witnesses and evaluation of CV and publications.
Assistance with development, review, writing of research protocols for clinical and experimental studies including pharmaceutical studies.
