To date, no studies have examined neural responses to a range of emotional expressions in PTSD with high dissociative symptoms. OBJECTIVE This study tested the hypothesis that PTSD patients with high dissociative symptoms will display increased ev...

Dissociative disorder includes dissociative amnesia, depersonalization and the realization that they can occur when a person exposes to severe psychiatric stressful events that they have strong negative emotion for him and then he cannot cope with them, so use unsuitable strategies for coping such as memory loss (d...

The kinetics of electron attachment to CF(3) as a function of temperature (300-600 K) and pressure (0.75-2.5 Torr) were studied by variable electron and neutral density attachment mass spectrometry exploiting dissociative electron attachment to CF(3)Br as a radical source. Attachment occurs through competing dissociative (CF(3) + e(-) → CF(2) + F(-)) and non-dissociative channels (CF(3) + e(-) ...

OBJECTIVE The goal of this study was to determine the frequency of dissociative disorders in Dutch psychiatric inpatients.

Patients scoring 25 and higher and a random selection of patients scoring lower than 25 were blindly interviewed with the Stru...

Some drugs of abuse may produce dissociative symptoms, but this aspect has been understudied. We explored the dissociative potential of three recreational drugs (3,4-methylenedioxymethamphetamine (MDMA), cannabis, and cocaine) during intoxication and compared their effects to literature reports of dissociative states in various samples. Two placebo-controlled studies were conducted. In Study 1 ...

Criminal acts can be performed in a dissociative state. Since a percentage of male and female patients with dissociative disorders act out aggression and display criminal behaviors, some of them may be found in the criminal justice system. This case report demonstrates that the long-term failure to diagnose dissociative identity disorder in a forensic psychiatric patient permitted the continued...
