Quantitative differential diagnostics in dementia
cNeuro cDSI is a tool for clinical decision support in dementia based on combination of imaging, lab results and clinical data.
- Cloud-based tool running in a standard browser.
- Comparison of patient’s data to data from previously diagnosed patients providing a quantitative estimate about patient’s similarity to different disease groups.
- Intuitive and interactive visualization of the similarity.
- Decision models available for etiology and progression.
- Patient data supported: clinical and neuropsychological test data, MRI imaging biomarkers, CSF biomarkers and APOE gene.
- Cloud-based – software runs in a standard web browser.
- Computation of disease state index measuring the similarity of the patient to previously diagnosed patients.
- Data sources supported:
- Clinical and neuropsychological tests: MMSE, RAVLT/CERAD recall & delayed recall, TMT A&B, Animal fluency, NPI.
- MRI imaging biomarkers from cMRI: volumes, computed MTA, GCA (global and local), Fazekas.
- Biomarkers: CSF biomarkers, APOE.
- Decision models available:
- Etiology: Alzheimer’s disease (AD), frontotemporal lobar degeneration (FTLD), vascular dementia (VaD), cognitively normal (CN).
- Progression: stable and progressive mild cognitive impairment.
- Compact visualization of all data using the patented disease state fingerprint technology.

Indications for Use
cNeuro cDSI is intended for visualization of imaging biomarkers and other clinical data for a patient being evaluated for a suspected neurodegenerative disease and for comparing these to corresponding values from previously diagnosed patients. The software is intended to provide clinical decision support to healthcare professionals by enabling them to review how biomarkers or clinical test results, individually or combined together, compares to distributions of different neurodegenerative diseases. The intended user profile covers healthcare professionals who work with patients being evaluated for a suspected neurodegenerative disease. The intended operational environment is an office-like environment with a computer.
