The Cognitive Functions Dementia Battery: A Novel Computerized Tool for Neurocognitive Disorders

Area of Science:

• Neuroscience
• Psychology
• Medical Informatics

Background:

• Neurocognitive disorders require reliable assessment tools.
• The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) outlines key cognitive domains.
• Computerized assessments offer potential for standardized evaluation.

Purpose of the Study:

• To examine the psychometric properties of the Cognitive Functions Dementia (CFD) battery.
• To assess the clinical validity of the CFD for diagnosing neurocognitive disorders.
• To establish normative data for healthy individuals.

Main Methods:

• Confirmatory factor analyses (CFA) and multi-group CFA were used for structural validity and measurement invariance.
• Internal consistency and re-test reliability were evaluated.
• Receiver operating characteristic (ROC) analyses assessed diagnostic accuracy against healthy controls.

Main Results:

• CFA confirmed the proposed five-domain structure of the CFD, including attention, memory, language, executive functions, and perceptual-motor skills.
• The overall CFD-Index factor was validated.
• High internal consistency and re-test reliability were observed for all CFD indices.
• CFD indices accurately discriminated between patients with neurocognitive disorders and healthy participants.

Conclusions:

• The Cognitive Functions Dementia (CFD) battery is a psychometrically sound and clinically valid computerized instrument.
• CFD demonstrates high reliability and accuracy in characterizing neurocognitive dysfunction.
• This tool can aid in the assessment and diagnosis of neurocognitive disorders.
