The attribute hierarchy method (AHM) (Leighton, Gierl, & Hunka, 2004), which is based on the assumption that test items can be described by a set of hierarchically ordered attributes, is designed to estimate examinees’ level of competency as well as their profiles for mastering a set of attributes. The AHM, by incorporating the assumption of attribute dependency, brings an important cognitive p...

OBJECTIVES Evaluate the reliability of using diagnosis codes and prescription data to identify the timing of symptomatic onset, cognitive assessment and diagnosis of Alzheimer's disease (AD) among patients diagnosed with AD. METHODS This was a retrospective cohort study using the UK Clinical Practice Research Datalink (CPRD). The study cohort consisted of a random sample of 50 patients with f...

OBJECTIVE Existing screening tools for HIV-Associated Neurocognitive Disorders (HAND) may lack the accuracy required for clinical use. We hypothesized that the diagnostic accuracy of the Montreal Cognitive Assessment (MoCA) as a screening tool for HAND might be improved with a stronger scoring methodology. DESIGN Two hundred HIV-positive participants aged 18-65 years completed the MoCA and a ...

INTRODUCTION The purpose of the current study is to assess the psychometric properties of Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog) on patients with mild cognitive impairment (MCI) and mild Alzheimer's disease (AD) in a multicultural Asian context. MATERIALS AND METHODS Sixty-four mild AD patients (mean age ± SD; 72.24 ± 7.88 years), 80 MCI patients (66.44 ± 7.45 year...

The newest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) introduces several changes in the diagnostic criteria for dementia and other cognitive disorders. Some of these changes may prove helpful for clinical and forensic practitioners, particularly when evaluating less severe cognitive impairments. The most substantial change is that the cognitive disorder-not oth...

Conflict of interest: none. ABSTRACT Objective: To evaluate the diagnostic sensitivity, specificity, and agreement of the Dementia Rating Scale with clinical diagnosis of cognitive impairment and to compare its psychometric measures with those from Mini Mental State Examination. Methods: Eighty-six elders from a long-term care institution were invited to participate in a study, and fifty-eight ...

Mild cognitive impairment (MCI) is frequent in Parkinson's disease (PD). Recently proposed criteria for MCI in PD (PD-MCI) indicate level I diagnosis based on abbreviated assessment and level II based on comprehensive neuropsychological evaluation. The study explored the sensitivity and specificity of the Italian versions of three neuropsychological tests for level I diagnosis of PD-MCI. We rec...

BACKGROUND accurately identifying individuals with cognitive impairment is difficult. Given the time constraints that many clinicians face, assessment of cognitive status is often not undertaken. The intent of this study is to determine the diagnostic accuracy of the Alzheimer's questionnaire (AQ) in identifying individuals with mild cognitive impairment (MCI) and AD. METHODS utilising a case...
