Impaired Prepulse Inhibition of Acoustic Startle in Obsessive-Compulsive Disorder
View on Elsevier
On the influence of baseline startle reactivity on the indexation of prepulse inhibition.
TLDR
The results revealed that both indexations of PPI were affected by the magnitude of the baseline startle, and the authors highlight the pitfalls of different methods to index PPI, especially when startle reactivity differs considerably between groups under comparison, and offer practical recommendations to satisfactorily deal with such baseline differences.

Elevated impulsivity and impaired decision-making cognition in heavy users of MDMA (“Ecstasy”)

The results suggest that heavy use of MDMA may elevate behavioral impulsivity and impair decision-making cognition possibly mediated by a selective impairment of the 5-HT system.

Dopamine D2/3- and μ-opioid receptor antagonists reduce cue-induced responding and reward impulsivity in humans
TLDR
It is demonstrated that a selective blockade of dopamine D2/D3 receptors reduces cue-induced responding and reward impulsivity in healthy humans andagonizing μ-opioid receptors has similar effects for cue- induced responding and to a lesser extent for reward impulse.

Memory deficits in abstinent MDMA (ecstasy) users: neuropsychological evidence of frontal dysfunction
TLDR
The results suggest that the memory de.cits of MDMA users are not only the result of a temporal or hippocampal dysfunction, but also of a dysfunction of regions within the frontal cortex.

Effects of serotonergic and noradrenergic antidepressants on auditory startle response in patients with major depression
TLDR
These results provide the first evidence for different effects of noradrenergic and serotonergic antidepressants on the startle response in depressed patients.

Executive performance of depressed suicide attempters: the role of suicidal ideation
TLDR
The results suggest that executive deficits seen in depressive suicide attempters have a state-dependent component, and suggest suicidal ideation is clearly associated with impaired cognitive performance.
