It is speculated that etiological factors responsible for mental disorders are also in conflict with the 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. Use of clerodendrum sp. for treating tic disorders or psychiatric disorders with sensorimotor gating deficits Download PDF Info Publication number US20110159129A1. US20110159129A1 US12/827,412 US82741210A US2011159129A1 US 20110159129 A1 US20110159129 A1 US 20110159129A1 US 82741210 A US82741210 A US 82741210A US 2011159129 A1 US2011159129 A1 Deficiencies in sensorimotor gating contribute to the manifestation of a number of neuropsychiatric disorders. PPI refers to a reduction of the startle reflex following exposure to a weak-intensity prepulse that is administered immediately prior to a startle stimulus; this is a well-established method used to evaluate sensorimotor gating .

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. via … Sensorimotor gating deficits in bipolar disorder patients with acute psychotic mania. Biological Psychiatry, 50, 418-424.

The . Substantial evidence suggests that these disorders of impaired “gating” are all associated with dysfunction within interconnected cortico-striatopallido-thalamic circuitry.

Biological Psychiatry, 50, 418-424. References 32 healthy controls and 35 bipolar patients (23 mixed, 11 manic, and 1 undefined) were recruited from ongoing pharmacokinetic studies in which they were enrolled independent of the present sensory gating protocol Deficits of prepulse inhibition manifest in the inability to filter out the unnecessary information; they have been linked to abnormalities of sensorimotor gating. Such deficits are noted in patients suffering from illnesses like schizophrenia and Alzheimer's disease , and in people under the influence of drugs, surgical manipulations, or mutations. Sensory input may be abnormal and trigger focal dystonia, or defective “gating” may cause an input–output mismatch in specific motor programs. Altogether, several observations strongly support the idea that sensorimotor integration is impaired in focal dystonia. 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).

Introduction Sleep disorders are commonly associated with prevalent neuropsychiatric dis-orders such as mood disorders and anxiety disorders . It is speculated that etiological factors responsible for mental disorders are also in conflict with the 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. Use of clerodendrum sp.
Disrupted sensorimotor gating has been found in various neuropsychiatric conditions which are characterized by impaired attention, poor impulse control, dysfunctional dopamine neurotransmission, and neurodevelopmental deficits.
