Gating of Sensory Information Differs in Patients With Interstitial Cystitis/Painful Bladder Syndrome.
Summary of "Gating of Sensory Information Differs in Patients With Interstitial Cystitis/Painful Bladder Syndrome."
PURPOSE:
Altered sensory processing in interstitial cystitis/painful bladder syndrome cases may result from a deficiency of the central nervous system to adequately filter incoming visceral afferent information. We used prepulse inhibition as an operational measure of sensorimotor gating to examine early pre-attentive stages of information processing in females with interstitial cystitis/painful bladder syndrome and healthy controls. MATERIALS AND
METHODS:
We assessed prepulse inhibition in 14 female patients with interstitial cystitis/painful bladder syndrome and 17 healthy controls at 60 and 120-millisecond prepulse-to-startle stimulus intervals. We evaluated group differences in prepulse inhibition, and relationships between prepulse inhibition, neuroticism and acute stress ratings.
RESULTS:
Patients showed significantly decreased prepulse inhibition at 60 and 120-millisecond prepulse intervals. The prepulse inhibition deficit was related to acute stress ratings in the patients. However, increased neuroticism appeared to mitigate the prepulse inhibition deficit in those with interstitial cystitis/painful bladder syndrome, possibly reflecting greater vigilance.
CONCLUSIONS:
Compared to healthy controls, female patients with interstitial cystitis/painful bladder syndrome had decreased ability to adequately filter incoming information and perform appropriate sensorimotor gating. These results suggest that a possible mechanism for altered interoceptive information processing in interstitial cystitis/painful bladder syndrome cases may be a general deficit in filtering mechanisms due to altered pre-attentive processing.

Medical and Biotech [MESH] Definitions
Sensory Gating
The ability of the BRAIN to suppress neuronal responses to external sensory inputs, such as auditory and visual stimuli. Sensory filtering (or gating) allows humans to block out irrelevant, meaningless, or redundant stimuli.
Cystitis, Interstitial
A condition with recurring discomfort or pain in the URINARY BLADDER and the surrounding pelvic region without an identifiable disease. Severity of pain in interstitial cystitis varies greatly and often is accompanied by increased urination frequency and urgency.
Feedback, Sensory
A mechanism of communicating one's own sensory system information about a task, movement, skill, etc.
Ganglia, Spinal
Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.
Cystitis
Inflammation of the URINARY BLADDER, either from bacterial or non-bacterial causes. Cystitis is usually associated with painful urination (dysuria), increased frequency, urgency, and suprapubic pain.
