Wearable Sensor Cognitive Assessment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cognitive function testing methods are limited by their reliance on verbal cues, require supervised clinical settings, and lack ecological validity, making them inadequate for widespread access and self-assessment, especially for neurological and neuropsychiatric conditions.
Innovation Solution
A system utilizing wearable sensors to monitor physical parameters, triggering cognitive tests based on deviations from predetermined baselines, allowing for real-time assessment and monitoring of cognitive function, and providing feedback to individuals and healthcare professionals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cognitive testing is conducted in supervised clinical settings with verbal cues, then measurement precision is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent replaces traditional mechanical/verbal testing methods with electronic sensors and automated systems. Sensors detect physiological parameters (heart rate, skin conductance, muscle tension) to objectively measure cognitive states, eliminating the need for verbal cues and clinician supervision while maintaining measurement precision.
Solution Approach 2:
The system enables individuals to conduct cognitive assessments independently without clinician involvement. The automated analysis of sensor data allows users to interpret their own cognitive function results, making the testing process self-service accessible to anyone with the device.
2Measurement precision
If traditional cognitive tests are administered discretely in clinical settings, then measurement precision is improved, but productivity and frequency of assessment deteriorate
Solution Approach 1:
The patent transforms discrete, periodic cognitive assessments into continuous monitoring. Sensors continuously collect physiological data, and the system continuously analyzes this data to track cognitive function changes in real-time, enabling frequent assessment without the limitations of scheduled clinical visits.
Solution Approach 2:
The system performs repeated cognitive assessments at regular intervals through continuous sensor monitoring. By periodically analyzing physiological parameters, the system maintains measurement precision while dramatically increasing the frequency and productivity of assessments compared to traditional single-visit testing.
3Measurement precision
If cognitive testing requires clinical supervision and formal environments, then measurement precision is improved, but adaptability to real-world settings deteriorates
Solution Approach 1:
The patent creates a universal testing system that functions equally well in clinical and real-world settings. The sensor-based approach works across diverse environments (home, workplace, outdoor), making the system adaptable to any location while maintaining measurement precision through objective physiological measurement rather than environment-dependent verbal testing.
Data Source
AI summary
A method for neurological analysis and treatment is described. In one embodiment, a server sends a request to a wearable device for sensor data of a patient. The server receives sensor data from the wearable device, and sends instructions to the wearable device to present a cognitive test based on the sensor data. The server receives from the wearable device, results of the cognitive test, compares the results against a baseline, and determines an assessment of the user. A notification may be sent to the wearable device based on the assessment. A wearable device for use in the analysis and treatment is also described.
