What this trial studies

This observational cohort study aims to evaluate the effectiveness of a blood test measuring neurofilament light chain levels and voice acoustic analysis in diagnosing dementia among individuals presenting with cognitive complaints. Participants will undergo a blood draw and speech assessment, with follow-up evaluations at 12 months to complete questionnaires and cognitive scales. The study also includes optional genetic testing for those at risk of fronto-temporal dementia, utilizing a simple saliva sample. The goal is to address the lack of standardized diagnostic tests for dementia and improve early detection.

Who should consider this trial

Good fit: Ideal candidates are individuals presenting with cognitive complaints or potential neurodegenerative disorders within the Eastern Health services network.

Not a fit: Patients with a prognosis of less than 12 months or those without cognitive complaints will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and timely diagnoses of dementia, reducing patient and caregiver stress.

How similar studies have performed: While there have been studies exploring blood biomarkers for dementia, this approach combining blood tests and voice analysis is relatively novel.
