Current Clinical Psychopharmacology in Borderline Personality Disorder.

Background: Patients with Borderline Personality Disorder (BPD) manifest affective and behavioral symptoms causing personal distress, relationship difficulties, and reduced quality of life with global functioning impairment, mainly when the disease takes an unfavorable course. A substantial amount of healthcare costs is dedicated to addressing these issues. Many BPD patients receive medications, mostly those who do not respond to psychological interventions.

Abnormal sensory gating in patients with different types of focal dystonias.

Background: Movement execution in healthy individuals increases the somatosensory temporal discrimination threshold. These changes are a result of mechanisms of sensory gating at the subcortical level. Although the somatosensory temporal discrimination threshold is abnormally increased in patients with focal dystonias, the effect of movement execution on somatosensory temporal discrimination in dystonic patients is unknown.

Voluntary Movement Takes Shape: The Link Between Movement Focusing and Sensory Input Gating.

The aim of the study was to investigate the relationship between motor surround inhibition (mSI) and the modulation of somatosensory temporal discrimination threshold (STDT) induced by voluntary movement. Seventeen healthy volunteers participated in the study. To assess mSI, we delivered transcranial magnetic stimulation (TMS) single pulses to record motor evoked potentials (MEPs) from the right abductor digiti minimi (ADM; "surround muscle") during brief right little finger flexion.

Abnormal Temporal Coupling of Tactile Perception and Motor Action in Parkinson's Disease.

Evidence shows altered somatosensory temporal discrimination threshold (STDT) in Parkinson's disease in comparison to normal subjects. In healthy subjects, movement execution modulates STDT values through mechanisms of sensory gating. We investigated whether STDT modulation during movement execution in patients with Parkinson's disease differs from that in healthy subjects.
