Computational Tools for Early Diagnosis of Memory Disorders

Completed

• Conditions: Frontotemporal Dementia; Mild Cognitive Impairment; Alzheimer Disease; Dementia, Vascular

• Registration Number: NCT02050464
• Lead Sponsor: University of Eastern Finland

Brief Summary

The Virtual Physiological Human: DementiA Research Enabled by IT (VPH-DARE@IT) is a four-year IT-project funded through the European Union (EU). The project consortium involves a total of 21 universities and industrial partners from 10 European countries. The project delivers the first patient-specific predictive models for early differential diagnosis of dementia and their evolution. An integrated clinical decision support platform will be validated / tested by access to a dozen databases of international cross-sectional and longitudinal studies. As a part of the VPH-DARE@IT project, a new prospective cohort will be collected in Kuopio. This prospective cohort will be used to test further the modeling approaches and tools developed by using the retrospective databases.

Detailed Description

The Virtual Physiological Human: DementiA Research Enabled by IT (VPH-DARE@IT) is a four-year IT-project funded through the European Union (EU). The project will develop multiscale models of the ageing brain in order to account simultaneously for the patient-specific biochemical, metabolic and biomechanical brain substrate, as well as for genetic, clinical, demographic and lifestyle determinants. An integrated clinical decision support platform will be validated and tested by access to a dozen databases of international cross-sectional and longitudinal studies.

Modeling approaches developed by using the retrospective databases will be tested using a new prospective cohort that will be collected in Kuopio as a part of the VPH-DARE@IT project. The study population at university of Eastern Finland (UEF) will be a total of 120 subjects: 20 healthy controls (HC), 20 mild to moderate Alzheimer's disease (AD) patients, 20 vascular dementia (VAD) patients, 20 fronto-temporal dementia (FTD) patients and 40 subjects with mild cognitive impairment (MCI). This study is referred as VPH-DARE@IT Prospective study in Kuopio or "ProsKuopio".

Inclusion Criteria

Inclusion criteria for subjects with dementia (AD, VAD, FTD) - The inclusion criteria will be based on international research criteria:

• Diagnosis of probable AD according to National Institute of Neurological and Communicative Disorders and Stroke Alzheimer's (NINCDS-ADRDA) criteria (McKhann et al.1984) and diagnosis of prodromal AD according to Dubois et al., 2007 criteria
• Diagnosis of FTD according to the clinical diagnostic criteria of Neary et al., 1998
• Diagnosis of VAD according to diagnostic criteria for research studies by the NINDSAIREN International Workshop (Román et al., 1993)

Inclusion criteria for subjects with MCI

• Referral because of cognitive impairments
• Diagnosis criteria for amnestic and nonamnestic MCI (Petersen, 2004, Petersen and Morris, 2005)

Inclusion criteria for control subjects

• Mini-mental state examination (MMSE) score above or equal to 27
• Overall score on the Clinical Dementia Rating (CDR) scale of 0

Exclusion Criteria

Exclusion criteria for all subjects

• Other causes of dementia
• Obvious brain, systemic or psychiatric disorders that could potentially affect cognitive functions such as stroke, severe depression, or endocrine disorders

Exclusion criteria for control subjects and subjects with MCI

• Diagnosis of dementia according to DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition) criteria at baseline

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Sensitivity, specificity and accuracy of models for diagnosis of memory disorders	during a single visit, i.e., day 1 and for one study group (MCI) after 18 month follow-up	The models developed the VPH-DARE project will be tested in this prospective cohort. Sensitivity, specificity and accuracy of the model will be tested in differential diagnosis between the study groups as well as the accuracy of prediction cognitive decline as measured by neuropsychological test battery in the MCI group.
