Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the optimal location and type of brain therapeutic interventions, such as pharmaceutical therapy injections and deep brain stimulation, are limited by trial-and-error approaches and lack personalization, making it difficult to effectively treat neurological conditions like Huntington's disease, Alzheimer's, and Parkinson's.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trial-and-error approaches are used to determine optimal brain therapeutic interventions, then treatment effectiveness can be achieved, but the process is time-consuming and lacks personalization
Solution Approach 1:
The system performs preliminary actions by creating a virtual circuit model of the patient's brain before actual treatment. The model is parameterized using pre-treatment imaging data (PET, MRI, fMRI) to simulate brain circuit behavior and predict therapeutic responses in advance, eliminating the need for time-consuming trial-and-error approaches during treatment determination.
Solution Approach 2:
The system creates a virtual copy (digital twin) of the patient's brain circuitry through computational modeling. This virtual model replicates the biological brain's neural circuits and can be manipulated computationally to predict treatment outcomes, replacing the need for physical trial-and-error interventions on the actual patient brain.
2Reliability
If trial-and-error approaches are used for brain therapeutic interventions, then treatment can be applied, but personalization to individual patient needs is lost
Solution Approach 1:
The system applies local quality by creating a personalized circuit model that captures region-specific characteristics of each patient's brain. The model incorporates patient-specific imaging data (PET for receptor binding, MRI for anatomy, fMRI for connectivity) to simulate local circuit behavior in different brain regions, enabling tailored treatment recommendations for each patient's unique neurological profile.
Solution Approach 2:
The system utilizes parameter changes by adjusting model parameters based on individual patient imaging data. The circuit model is parameterized using patient-specific values for receptor binding affinities, neural connectivity strengths, and circuit activation patterns, allowing the simulation to predict how different treatments would affect each patient's unique brain circuitry.
3Ease of manufacture
If conventional treatment planning methods are used, then treatments can be administered, but accuracy in determining optimal treatment location and type is reduced
Solution Approach 1:
The system implements feedback by continuously comparing simulated treatment outcomes with actual patient responses. The circuit model incorporates feedback loops that adjust predictions based on observed therapeutic effects, allowing iterative refinement of treatment recommendations and improving accuracy over time as patient response data becomes available.
Solution Approach 2:
The system replaces mechanical trial-and-error treatment approaches with computational simulation. Instead of physically testing multiple treatment options on the patient, the system uses computer-based circuit modeling to virtually test and rank treatment approaches, providing precise predictions about optimal treatment location, type, and dosage before actual administration.
