How does Theia work?

Each year, 15–20% of adults over 60 develop Mild Cognitive Impairment (MCI)¹. While 14.4% to 55.6% recover, many decline further². Yet, assessments are slow and unreliable, with over 50% of traditional neuropsychological tests requiring repetition³.

Theia transforms this process with a non-invasive, portable, and accurate solution, enabling fast, objective MCI mass pre screening and monitoring.

  • High sensitivity & specificity

Reliable assessment. Sensitivity 75%. Specificity of 95%.

  • All driven insight

Supports clinicians with data backed decisions.

  • Objective & quantifiable data

Ensures consistent cognitive evaluations

  • Portable & Easy-to-Use

Designed for seamless clinical integration.

  •  Fast & Efficient

Brain assessments in <20 minutes.

  • Scalable

Suitable for mass screenings and ready for broader research applications.

Applications

Theia is designed to differentiate individuals with Mild Cognitive Impairment (MCI) from cognitively healthy individuals by analyzing expected brain responses.

Clinical Use

Provides an objective, non-invasive assessment to support early MCI detection and cognitive health monitoring.

Research Applications

Enables the study of brain hemodynamics in the prefrontal cortex, making it suitable for cognitive research.

Screening & Prevention

Facilitates mass pre-screening, helping implement early interventions that aim at slowing cognitive decline.

Cognitive health monitoring

Allows real-time monitoring of cognitive function and recovery progress.

Design

1. An optimized contact-surface that maximizes ease of clean and comfort to the user.

2. Source-detector distances and locations have been carefully chosen to facilitate noise reduction and provide meaningful brain information.

3. Interchangeable dual LEDs, easy to replace.

4. Bluetooth and WiFi modules for wireless connections.

Design

The flexible probe was specially designed to ensure comfort by adapting to the curvature of the forehead – crucial for clinical applications.

An adjustable ratchet system for every head size, ensuring the accurate optodes placement.

Ergonomic design maximizing patient’s comfort during the clinical evaluation.

Technical Applications

Wireless

Bluetooth connection and battery powered to ensure its portability.

High Autonomy

Due to its low energy consumption, up to 6h of recordings on a single battery charge.

Light-weight and compact

Allowing the subject to move freely.

Dual LED light sources

That emit harmless light intensities.

High resolution fNIRS data

Sampling rate 10 Hz.

Multi-distance channel

Disposition for correct management of heterogeneous extracortical contamination.

3-axis accelerometers

In three axes for the motion artifacts management.

Cloud based

Processes data without storing it, ensuring seamless integration with the hospital IT systems.

Cybersecurity

Advanced encryption, GDPR & HIPAA compliance, and ISO 27001/13485 certified security.
