Background Sensorimotor gating abnormalities have been previously correlated with thought disturbance in schizophrenic patients. These correlative studies have led to the hypothesis that sensorimotor gating abnormalities may underlie thought disturbance.

The findings suggest diverse sensorimotor gating profiles amongst subgroups of violent offenders, with comorbid psychosis and DPD showing most impairment. This is consistent with a 'double dose' of deficit explanation amongst those with both diagnoses, explained at least in part by presence of antisocial personality traits and childhood psychosocial deprivation.

Within the P50 paradigm, N100 and P200 amplitudes were also assessed. Sensorimotor gating, or the ability of a sensory event to suppress a motor response, can be measured operationally via prepulse inhibition (PPI) of the startle response. One measure that is often used to evaluate the translational relevance of these models to human neuropsychiatric disease is prepulse inhibition of startle (PPI), an operational measure of sensorimotor gating. Deficient PPI characterizes several neuropsychiatric disorders but has been most extensively studied in schizophrenia. 2001-09-15 · The fact that sensorimotor gating disturbances have been found across a number of neuropsychiatric disorders associated with CSPT disturbances but with distinct phenomenologic characteristics may be a result of disturbances at different elements along the CSPT circuitry (Swerdlow and Koob 1990).

Sensorimotor gating disorders

Prepulse inhibition (PPI) of startle is an operational measure of the pre-attentive filtering process known as sensorimotor gating. Originally identified in pat The family of sensorimotor gating disorders: Comorbidities or diagnostic overlaps? Background: Prepulse inhibition (PPI) is an operational measure of sensorimotor gating and is impaired in a family of neuropsychiatric disorders characterized by abnormalities of inhibitory function. Adults with autistic disorder (AD) exhibit clinical features of inhibitory deficits, such as restrictive and repetitive behaviors, that may be explained by deficits in sensorimotor gating. Altogether, a reduced sensorimotor gating as an effect of supraphysiological hormonal status, anxiety disorders, SSRIs, and catecholaminergic genotype, implicate the putative relevance of lower PPI as an objective biological correlate of anxiety proneness in pregnant women.

Neuroimaging premenstrual dysphoric disorder: A systematic and critical review responsiveness, startle response, and sensorimotor gating in late pregnancy.

Also referred to as gating or filtering, sensory gating prevents an overload of irrelevant information in the higher cortical centers of the brain. Sensory gating can also occur in different forms through changes in both perception and sensation, affected by various factors such as "arousal, recent stimulus exposure, and selective attention. Alth Impaired Sensorimotor Gating in Unmedicated Adults with Obsessive–Compulsive Disorder Abstract.

In two distinct auditory paradigms sensory gating, indexed as P50 suppression, and sensorimotor gating, indexed as prepulse inhibition (PPI), startle reactivity, and habituation of the eye-blink startle response were examined. Within the P50 paradigm, N100 and P200 amplitudes were also assessed.

In many cases, this process becomes subjective, since the patient must calibrate the magnitude of his/her symptoms and therefore the severity of his/her disorder. A completely different approach is based on the study of the more vulnerable traits of cognitive disorders. Sensorimotor gating is impaired in male patients with bipolar disorder and depression. Objectives: Few studies have examined acoustic startle sensorimotor gating in bipolar disorder (BPD) despite the fact that patients with BPD have exhibited inhibitory dysfunctions on a variety of Sensorimotor gating in manic and mixed episode bipolar disorder - Carroll - 2007 - Bipolar Disorders - Wiley Online Library 2001-08-21 Sensorimotor Gating in Cocaine-Related Disorder with Comorbid Schizophrenia or Antisocial Personality Disorder PPI is an operational measure of sensorimotor gating or inhibition associated with frontal-executive functioning (Perry, Minassian, Lopez, Maron, & Lincoln, 2007) and is also found to be impaired Disorders in Sensorimotor Gating and Attentional Quantiﬁable Responses as Possible Endophenotypes Juan P.

as a possible risk indicator for different mental disorders, helping to deﬁne a speciﬁc endophenotype. Speciﬁcally, we examine different experimental procedures to measure impaired response in attention linked to sensorimotor gating as a possible personality trait involved in maladaptive behaviors. The schizophrenia group showed reduction in sensorimotor gating for both PPI-60 (SMD = −0.50, 95% CI = [−0.61, −0.39]) and PPI-120 (SMD = −0.44, 95% CI = [−0.54, −0.33]).

Sensorimotor Gating: Startle Submits to Presynaptic Inhibition Michael P. Nusbaum and Diego Contreras Prepulse inhibition is a type of sensorimotor gating that is disrupted in some neuropsychiatric disorders. Its cellular basis has eluded investigators but now, using a molluscan model system, a cellular mecha-nism has been established.
