Deficits in PPI have been repeatedly reported in patients with schizophrenia or other psychiatric disorders characterized by abnormalities in sensory, cognitive, or motor gating.

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. Functional and structural imaging studies suggest that obsessive–compulsive disorder (OCD) symptoms arise from INTRODUCTION. Obsessive–Compulsive Disorder (OCD) is a severe, chronic psychiatric Prepulse inhibition (PPI) of startle response is a well-established neurophysiological marker of sensorimotor gating ability in psychiatric patients including those with autism spectrum disorders (ASD). PPI has been utilized as an indicator of the central inhibitory function and is potentially linked to the clinical features of this disease.

Reductions in sensorimotor gating are theorized to reflect deficient central inhibitory functioning and underlie symptoms of several neuropsychiatric disorders, including the obsessions and compulsions of OCD (Swerdlow et al, 1993; Hoenig et al, 2005).

These correlative studies have led to the hypothesis that sensorimotor gating abnormalities may underlie thought disturbance. While sensory gating and sensorimotor gating have been proposed to be endophenotypic biomarkers for schizophrenia spectrum disorders, deficient gating is not exclusively attributable to schizophrenia. BackgroundPrepulse inhibition (PPI) of the acoustic startle reflex is an operational measure of sensorimotor gating. The findings on PPI deficits in bipolar disorder (BD) are inconsistent among studies due to various confounding factors such as gender.

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.

Sensorimotor gating, defined as the state-dependent regulation of transmission of sensory information to a motor system, is coming of age. It has been known for decades that sensory information does not have unfettered access to its targets in the central nervous system (CNS), as has the fact that sensorimotor gating often occurs via presynaptic inhibition of the activated sensory neuron(s) .

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.

Fernando Alonso. An important objective in this investigation is to clarify whether sensorimotor gating deficits are also present in other dopaminergic dysregulated disorders with inhibitory impairments. Attention deficit/hyperactivity disorder (ADHD) is a highly prevalent neuropsychiatric disorder that has its onset in early childhood and is characterized by symptoms of inattention and/or hyperactive Substantial evidence suggests that these disorders of impaired “gating” are all associated with dysfunction within interconnected cortico-striatopallido-thalamic circuitry. It is possible to quantify sensorimotor gating in psychiatric patients, and to study the neurobiology of gating … Functional and structural imaging studies suggest that obsessive–compulsive disorder (OCD) symptoms arise from dysfunction in cortico-striato-thalamo-cortical circuits. It has therefore been hypothesized that neurophysiological tasks subserved by these circuits should be abnormal in OCD patients. One neurocognitive probe associated with this circuitry is prepulse inhibition (PPI) of the Prepulse inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of an organism to a subsequent strong reflex-eliciting stimulus (pulse), often using the startle reflex.The stimuli are usually acoustic, but tactile stimuli (e.g.
