NCT06339190

Brief Summary

This cohort study aims to determine if a blood test can aid with diagnosing dementia in anyone presenting with cognitive complaints to a single healthcare network. The investigators will measure levels of a brain protein, Neurofilament light chain (Nfl), and assess changes in language using speech tests. Participants will have a single blood test and speech test, and will be followed up at 12-months to complete questionnaires and cognitive scales over the phone. The speech test will also be completed again at 12-months. Individuals at risk of a Fronto-temporal dementia syndrome will be eligible to complete optional genetic testing involving an 'at home' saliva sample.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

The study cohort will include any individual of all ages, ethnicities, identities and genders. This is to ensure that the findings are generalisable to other national healthcare networks and to provide maximum information on the utility of using blood-biomarker estimation in real-world clinical settings

You may qualify if:

  • All patients presenting to Eastern Health services with a cognitive complaint or potential neurodegenerative disorder

You may not qualify if:

  • Prognosis \<12 months
  • No cognitive complaint
  • Patients not involved within the single healthcare network

Biospecimen

Retention: SAMPLES WITH DNA

Blood samples will be used and processed for plasma and Nfl levels will be quantified using the Quanterix HD-X machine and single molecule array (Simoa). All participants will be offered participation in DNA and plasma banking for future research as an optional part of the study. DNA samples from participants who consent to this optional collection of plasma will contribute to international biobanking initiatives.
