The present invention relates to the use of a composition made from Clerodendrum for treating tic disorder or sensorimotor gating deficits, wherein the composition is particularly made from the leaves of the plant.
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.
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.

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 [4]. Sensorimotor gating in manic and mixed episode bipolar disorder.

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 sensorimotor gating, and impaired ‘gating’ may partly explain the failure of people with autistic disorders to inhibit repetitive thoughts and actions. Thus, we com-pared brain anatomy and sensorimotor gating in healthy people with Asperger’s syndrome and controls. We … 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. disorder to four different auditory prepulse intensities (2, 4, 8, or 16 dB above background) and found impaired sensorimotor gating for the 4–8 dB pair. According to the researchers, this finding contrasts PPI effectsobservedin schizophrenicpatients, for example, who display increased sensorimotor deficits with more intense lead stimuli.
Listing a study does not mean it has been evaluated by the U.S. Federal Government. The present invention relates to the use of a composition made from Clerodendrum for treating tic disorder or sensorimotor gating deficits, wherein the composition is particularly made from the leaves of the plant. disorder to four different auditory prepulse intensities (2, 4, 8, or 16 dB above background) and found impaired sensorimotor gating for the 4–8 dB pair.
Prepulse inhibition (PPI) of the acoustic startle reflex is an operational measure of sensorimotor gating that is amenable to cross-species comparisons. Deficits in PPI have been repeatedly reported in patients with schizophrenia or other psychiatric disorders characterized by abnormalities in sensory, cognitive, or motor gating.

Studies of sensorimotor gating allow investigators to comment on the spatial and temporal mapping of neurons, trait and state deficits, and vulnerability factors in the schizophrenic spectrum of disorders. By translating attentional theories into testable hypotheses, the neurobiology of schizophrenic disorders becomes clearer.
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.
Fundamental gating mechanisms appeared intact, while the pattern of deficits in trauma-affected refugees with PTSD point toward a different form of sensory overload, an overall neural hypersensitivity and disrupted the ability to down-regulate stimuli responses. Sensory gating describes neurological processes of filtering out redundant or unnecessary stimuli in the brain from all possible environmental stimuli. 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.

The sensitivity and meta-regression analysis showed that sample size, gender proportion, imbalance for gender, source of control group, and study continent were sources of heterogeneity ( P < .05) for both PPI-60 Although elemental sensation is normal in patients with tics, tics can be associated with sensory phenomena.
Thus, Dvl1 mutants may provide a model for
The so-called family of psychiatric gating disorders can be seen to be consonant with the broad importance of behavioral inhibition, attention, and information
PPI has been proposed to reflect a measure of sensorimotor gating or fil- tering. Deficits in PPI has been found in schizo- phrenia in various prepulse conditions. 8 May 2012 Sensory and Sensorimotor Gating Deficits after Neonatal Ventral for an animal model of neurodevelopmental disorders like schizophrenia.

Studies of sensorimotor gating allow investigators to comment on the spatial and temporal mapping of neurons, trait and state deficits, and vulnerability factors in the schizophrenic spectrum of disorders. By translating attentional theories into testable hypotheses, the neurobiology of schizophrenic disorders becomes clearer.
Because some forms of schizophrenia appear to be attributable to BACKGROUND Deficits in sensorimotor gating as assessed by prepulse inhibition (PPI) and habituation of the human startle response have been noted in schizophrenia and other patients with known dysfunction in the brain substrates that regulate PPI. During acute mania, bipolar disorder (BD) and schizophrenia patients present with symptoms that are similar. The present invention relates to the use of a composition made from Clerodendrum for treating tic disorder or sensorimotor gating deficits, wherein the composition is particularly made from … Sensorimotor gating, assessed by prepulse inhibition of startle, is reduced in and provides a cross-species endophenotype for a group of psychiatric gating disorders, including schizophrenia, bipolar disorder, autism, and ADHD. Sensorimotor Gating in Schizophrenia The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.

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.
