ClearSky Medical Diagnostics

Clearsky Medical Diagnostics

Overview

ClearSky Medical Diagnostics is a UK-based medical technology company specializing in the development of diagnostic and monitoring devices for neurodegenerative diseases, particularly [Parkinson's disease](/diseases/parkinsons-disease) and [Alzheimer's disease](/diseases/alzheimers-disease).

Products & Technology

CleverScan

ClearSky's flagship product is CleverScan, a portable neuroimaging device that uses near-infrared spectroscopy (NIRS) to detect changes in brain activity. The device is designed for use in clinical settings and at home.

How NIRS Works:

• Uses near-infrared light (700-1000 nm wavelength) to penetrate the skull
• Measures hemoglobin oxygenation changes in cortical tissue
• Provides real-time information about brain activation patterns
• Non-invasive, portable, and suitable for continuous monitoring

• Motor cortex activation during gait and hand movements
• Prefrontal cortex function during cognitive tasks
• Hemodynamic response differences in PD vs. healthy controls
• Monitoring disease progression and treatment response

PD Monitor

The company has developed specialized monitoring solutions for Parkinson's disease that track motor symptoms and disease progression through wearable sensors and AI-powered analysis.

| Feature | Description |
|---------|-------------|
| Tremor detection | Accelerometer-based quantification |
| Bradykinesia assessment | Movement speed and amplitude analysis |
| Gait analysis | Step timing, stride length, variability |
| Home monitoring | Continuous data collection |

Clinical Validation

Regulatory Status

• CE marked medical device for European markets
• FDA clearance pathway under exploration
• Class IIa medical device under EU MDR

Clinical Evidence

Near-infrared spectroscopy (NIRS) has demonstrated utility in Parkinson's disease research[@nearinfrared]:

• Motor cortex activation: PD patients show altered hemodynamic responses during finger tapping[@nirs_parkinson]
• Gait analysis: NIRS can distinguish PD from healthy controls during walking tasks
• Treatment monitoring: Levodopa effects visible in NIRS signals

Collaborations

• Multiple clinical studies for PD symptom monitoring
• Collaborations with UK NHS trusts and academic medical centers
• University partnerships for technology validation

Parkinson'S Disease Relevance

Diagnostic Potential

NIRS technology offers several advantages for PD diagnosis and monitoring:

Monitoring Applications

• Motor fluctuations: Track on/off periods through cortical activation patterns
• Treatment response: Objective measures of levodopa efficacy
• Disease progression: Longitudinal monitoring of cortical changes

Advantages Over Existing Tools

| Current Tool | Limitation | NIRS Advantage |
|--------------|------------|----------------|
| UPDRS | Subjective | Objective measurement |
| DaTscan | Invasive, expensive | Non-invasive, portable |
| Wearables | Limited brain data | Cortical activation |
