Posteromedial Cortex Rhythm Modulation for Dissociative Disorders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The underlying cellular and circuit mechanisms of dissociative states, such as those observed in dissociative disorders like PTSD and schizophrenia spectrum disorders, remain unknown, leading to ineffective treatments for disrupting normal cognitive processing integration.
Innovation Solution
Modulation of rhythmic neural activity in the posteromedial cortex through agents that target HCN pacemaker channels, NMDA receptors, or monoamine oxidase, using inhibitors or modulators to treat dissociative disorders and induce or suppress dissociative symptoms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HCN pacemaker channels are inhibited to modulate rhythmic neural activity in the posteromedial cortex, then dissociative symptoms are reduced and therapeutic benefit is achieved, but normal cognitive processing integration may be disrupted
Solution Approach 1:
The patent applies parameter changes by modulating the rhythmic neural activity in the posteromedial cortex through HCN channel inhibition. By changing the electrophysiological parameters of neuronal firing patterns (specifically targeting theta-rhythm oscillations), the treatment achieves therapeutic effect while the localized nature of the modulation aims to minimize broader cognitive disruption.
Solution Approach 2:
The invention employs local quality by specifically targeting the posteromedial cortex region for HCN channel inhibition. This localized approach concentrates the therapeutic effect in the brain region most associated with dissociative symptoms, thereby potentially reducing unwanted disruption to other cognitive functions that depend on different brain regions.
2Reliability
If agents are used to modulate rhythmic neural activity in the posteromedial cortex, then dissociative symptoms are treated, but the underlying cellular and circuit mechanisms remain unknown and difficult to target
Solution Approach 1:
The patent uses HCN pacemaker channels as an intermediary target. Rather than attempting to directly manipulate complex neural circuits or understand all underlying mechanisms, the invention identifies HCN channels as a pharmacologically accessible mediator that influences rhythmic neural activity in the posteromedial cortex, thereby treating dissociative symptoms without requiring complete understanding of all cellular and circuit mechanisms.
3Reliability
If HCN channel inhibitors are administered to treat dissociative disorders, then therapeutic benefits are achieved for conditions like PTSD and schizophrenia, but selective uncoupling of affective responses from sensory percepts may occur
Solution Approach 1:
The patent applies partial action by using HCN channel inhibition to achieve sufficient modulation of rhythmic neural activity in the posteromedial cortex to treat dissociative symptoms, without completely blocking all neural processing. This partial modulation approach aims to restore normal integration of cognitive processing while avoiding excessive suppression that could cause affective-sensory uncoupling.
