Audio-Based Cognitive Assessment for Remote MCI Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cognitive testing systems require patients to visit an in-office setting, which is time-consuming, costly, and inconvenient, posing barriers to diagnosis and treatment for cognitive impairments.
Innovation Solution
A system utilizing audio files recorded on a computing device, such as a smartphone, to analyze neuromuscular tasks like finger tapping and gait movements, generating scores indicative of cognitive function for remote diagnosis and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are placed on the patient in an in-office setting to analyze movements for cognitive status evaluation, then measurement precision is improved, but loss of time and ease of operation deteriorate due to the requirement of in-person visits
Solution Approach 1:
The patent replaces the mechanical sensor-based movement analysis system with an acoustic system that uses audio recordings of speech and motor tasks. The audio-based cognitive assessment system captures speech samples and motor task sounds, then analyzes acoustic features to evaluate cognitive status, eliminating the need for physical sensors and in-office visits while maintaining diagnostic capability
Solution Approach 2:
The patent introduces audio recordings as an intermediary medium between the patient and the cognitive assessment system. Instead of direct sensor contact or in-person evaluation, the audio files serve as a mediator that captures and transmits cognitive function information, enabling remote assessment while preserving measurement accuracy
2Reliability
If in-office sensor-based cognitive testing is implemented, then reliability of diagnosis is improved, but ease of operation and accessibility worsen due to the need for specialized equipment and facilities
Solution Approach 1:
The patent enables patients to perform cognitive assessment themselves by recording audio during motor tasks and speech activities using their own devices. The system guides patients through self-administered cognitive tests where they record their voice and motor task sounds, then the system automatically analyzes the recordings to provide cognitive function evaluation, making the process convenient and accessible
Solution Approach 2:
The patent creates a universal cognitive assessment system that works across multiple platforms and devices. The audio-based approach can be implemented on smartphones, tablets, or computers without requiring specialized medical equipment or facilities, making cognitive testing accessible to anyone with a basic audio recording device
3Measurement precision
If traditional sensor-based cognitive assessment is used, then measurement precision is maintained, but device complexity and cost increase due to the need for specialized sensors and in-office infrastructure
Solution Approach 1:
The patent replaces expensive, complex sensor systems with inexpensive audio recording technology that is already widely available. Instead of requiring specialized medical sensors and infrastructure, the system uses standard audio recording capabilities of consumer devices, dramatically reducing system complexity and cost while maintaining measurement precision through sophisticated acoustic analysis algorithms
Data Source
AI summary
A system and method are provided for diagnosing mild cognitive impairment. The system and method utilize one or more computing devices to instruct a user to record the performance of one or more neuromuscular commands, such as finger tapping, heal tapping, or gait movements. The system and method analyze one or more audio components of the performance to determine one or more attributes, such as a speed of performance, a rhythm of performance, a variability in performance, or a volume intensity of performance. The system and method utilize the one or more attributes to generate at least one score which can be utilized to determine if cognitive impairment exists in the user, or to monitor progression of cognitive impairment in the user.
