Evaluating cognition in an elderly cohort via telephone assessment

Objective: Longitudinal neuropsychological assessment provides the opportunity to observe the earliest transition to cognitive impairment in healthy, elderly individuals. We examined the feasibility, and its comparability to in-person assessment, of a telephone administered battery of established neuropsychological measures of cognitive functioning in healthy, elderly women.; Methods: Fifty-four women (age = 79 +/- 7.7; education = […]

A comparison of neuropsychiatric and cognitive profiles in delirium, dementia, comorbid delirium-dementia and cognitively intact controls

Purpose: Delirium and dementia have overlapping features that complicate differential diagnosis. Delirium symptoms overshadow dementia symptoms when they co-occur, but delirium phenomenology in comorbid cases has not been compared to both conditions alone.; Methods: Consecutive adults with DSM-IV delirium, dementia, comorbid delirium-dementia and cognitively intact controls were assessed using the Revised Delirium Rating Scale (DRS-R98) […]

Screening for dementia using telephone interviews. An evaluation and reliability study of the Telephone Interview for Cognitive Status (TICS) in its modified German version

Background: To assess cognitive impairment or dementia in epidemiologic studies using telephone interviews for data acquisition, valid, reliable and short instruments suitable for telephone administration are required. For the Telephone Interview for Cognitive Status (TICS) in its modified German version, the only instrument used in Germany so far, more data on reliability and practicability are […]

The reliability of assigning individuals to cognitive states using the Mini Mental-State Examination: a population-based prospective cohort study

Background: Previous investigations of test re-test reliability of the Mini-Mental State Examination (MMSE) have used correlations and statistics such as Cronbach’s α to assess consistency. In practice, the MMSE is usually used to group individuals into cognitive states. The reliability of this grouping (state based approach) has not been fully explored.; Methods: MMSE data were […]

Informant-reported cognitive symptoms that predict amnestic mild cognitive impairment

Background: Differentiating amnestic mild cognitive impairment (aMCI) from normal cognition is difficult in clinical settings. Self-reported and informant-reported memory complaints occur often in both clinical groups, which then necessitates the use of a comprehensive neuropsychological examination to make a differential diagnosis. However, the ability to identify cognitive symptoms that are predictive of aMCI through informant-based […]

The KICA Screen: the psychometric properties of a shortened version of the KICA (Kimberley Indigenous Cognitive Assessment)

Aim: To describe the development and psychometric properties of the KICA (Kimberley Indigenous Cognitive Assessment) Screen.; Methods: A short 10-item version of the KICA, the KICA screen was developed from original data of 363 Aboriginal people. The KICA Screen was subsequently independently validated in a non-random sample of 55 people living in Northern Queensland.; Results: […]

Prediction of dementia in primary care patients

Background: Current approaches for AD prediction are based on biomarkers, which are however of restricted availability in primary care. AD prediction tools for primary care are therefore needed. We present a prediction score based on information that can be obtained in the primary care setting.; Methodology/principal Findings: We performed a longitudinal cohort study in 3.055 […]

Psychometric properties of the Italian version of the Scales for Outcomes in Parkinson’s disease- Cognition (SCOPA-Cog)

The Scales for Outcomes in Parkinson’s disease-Cognition (SCOPA-Cog) has been shown to be a clinimetrically rigorous and valid instrument for a disease-oriented neuropsychological assessment of Parkinson’s disease (PD) patients. In the present study we evaluated the psychometric properties of the Italian version of the SCOPA-Cog in 121 PD patients. The scale explores memory, attention, and […]

Development and evaluation of a computerized test battery for Alzheimer’s disease screening in community-based settings

Aim: To evaluate the capability of a computerized test battery for Alzheimer’s disease screening which has been newly developed to provide a standardized and efficient method for widespread use in routine clinical and community-based settings.; Methods: Participants were 72 individuals diagnosed with Alzheimer’s disease and 102 healthy elderly individuals. Both groups were tested by the […]

Japanese-English language equivalence of the Cognitive Abilities Screening Instrument among Japanese-Americans

Background: The Cognitive Abilities Screening Instrument (CASI) was designed for use in cross-cultural studies of Japanese and Japanese-American elderly in Japan and the U.S.A. The measurement equivalence in Japanese and English had not been confirmed in prior studies.; Methods: We analyzed the 40 CASI items for differential item functioning (DIF) related to test language, as […]
