Solution Overview

Problem

Current epilepsy diagnosis and treatment assessment are subjective and inefficient, often leading to delayed or inaccurate diagnosis and prolonged seizure activity due to reliance on clinical interpretation of seizure descriptions and EEG readings, with limited availability of simultaneous video-EEG and unfeasible seizure recording.

Innovation Solution

A system that generates a network model from patient brain data to compute seizure frequency and susceptibility, using synthetic brain activity data to predict epilepsy likelihood and assess treatment efficacy, transitioning from subjective clinical evaluation to objective quantitative calculation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If simultaneous video-EEG is used to directly observe seizures, then diagnostic accuracy is improved, but cost and availability deteriorate

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidcost and availability
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a computational copy of brain network dynamics through synthetic data generation. Instead of using expensive video-EEG equipment to observe actual seizures, the system generates synthetic brain activity data that replicates seizure patterns based on routine EEG data, thereby achieving diagnostic accuracy without requiring costly specialized equipment.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical/video-EEG observation system with a computational modeling system. Rather than physically recording and analyzing video-EEG data during seizures, the system uses computational models to simulate brain network dynamics and predict seizure likelihood from routine EEG data, substituting mechanical observation with computational analysis.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If prolonged EEG recordings with provocation are used to capture seizures, then diagnostic certainty is improved, but time and cost deteriorate

Engineering Contradiction:
Improvediagnostic certaintyVSAvoidrecording time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary computational analysis on routine EEG data to assess seizure susceptibility before prolonged recording is needed. By generating synthetic data and computing seizure likelihood metrics from standard EEG recordings, the system can identify patients who need further monitoring and predict those at high risk, reducing the need for time-consuming prolonged recordings for all patients.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces computational modeling as an intermediary between routine EEG data and diagnostic certainty. Instead of directly requiring prolonged recordings to achieve diagnostic confidence, the system uses computational models as an intermediate step that extracts predictive information from routine data, reducing the need for extended monitoring.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional trial-and-error AED prescription is used, then treatment coverage is improved, but treatment efficiency deteriorates

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements a feedback mechanism where computational models continuously assess seizure susceptibility in response to AED treatment. By monitoring changes in synthetic data metrics and seizure likelihood predictions, the system provides objective feedback on treatment efficacy, allowing clinicians to adjust medication based on quantitative response data rather than waiting for trial-and-error progression.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses parameter changes in computational models to assess treatment response. By tracking changes in synthetic brain activity parameters and seizure susceptibility metrics in response to AED administration, the system quantifies treatment effects, enabling more efficient medication selection compared to conventional methods that rely on observing seizure frequency changes over extended periods.

Inventive Principle:

Engineering Contradiction:

Solution Approach 1:

The patent introduces computational modeling as an intermediary between raw EEG data and clinical interpretation. The system generates synthetic brain activity data and calculates objective seizure susceptibility metrics that serve as a bridge between complex EEG patterns and clinical decision-making, providing quantified assistance that maintains clinical flexibility while improving diagnostic precision.

Inventive Principle:

Solution Approach 2:

The patent creates a composite diagnostic approach combining subjective clinical expertise with objective computational metrics. By integrating clinician interpretation with quantitative synthetic data analysis and seizure likelihood predictions, the system forms a composite diagnostic tool that leverages both human flexibility and machine precision.

AI summary

Assessing Susceptibility to Epilepsy and Epileptic Seizures A method and system adapted to assist with assessing susceptibility to epilepsy and/or epileptic seizures in a patient receives (202) patient brain data and generates (204) a network model from the received patient brain data. The system further generates (206) synthetic brain activity data in at least some of the nodes of the network model and computes (208) seizure frequency from the synthetic brain activity data by monitoring transitions from non-seizure states to seizures states in at least some of the nodes over time. The system further includes a device (104, 110) configured to use the seizure frequency to compute (210) a likelihood of susceptibility to epilepsy and/or epileptic seizures in the patient, and a device (104, 110) configured to compare (212) the computed likelihood with another likelihood of susceptibility to epilepsy and/or epileptic seizures in order to assess whether the likelihood has increased or decreased.
