OBJECTIVES To determine whether the Alzheimer's Disease Screen for Primary Care (ADS-PC) is more sensitive to early dementia than the Mini-Mental State Examination (MMSE) and whether it has as high a misclassification rate in minority patients and patients with limited education. DESIGN Cross-sectional validation study. SETTING Urban geriatric primary care practice. PARTICIPANTS Three hun...

BACKGROUND AND PURPOSE A screening test is required to improve the diagnosis of poststroke cognitive impairment. The Montreal Cognitive Assessment (MoCA), a newly designed screening test, has been found to be more sensitive than Mini-Mental State Examination (MMSE), but its clinical value has not been established by means of a comprehensive neuropsychological battery. This study was designed to...

A novel sparse channel state information (CSI) estimation scheme is proposed for orthogonal time frequency space (OTFS) modulated systems, in which the pilots are directly transmitted over time-frequency (TF)-domain grid estimating delay-Doppler (DD)-domain CSI. The CSI model leads to a reduction pilot overhead as well training duration required. Furthermore, it does not require DD-domain guard...

We recently completed an audit on cognitive testing used in routine practice within our Older People Community Mental Health Team in East Dorset, U.K. We measured the frequency of use of the Addenbrooke’s Cognitive Examination (ACE) following its introduction as the baseline test for cognition, comparing it to the Mini-mental State Examination (MMSE) (Folstein et al., 1975). Published research ...

An alternative approach to decision-feedback equalization with finite impulse response feedforward and feedback filters is presented. Instead of the conventional design criterion of minimum mean-squared error (MMSE), a maximum signalto-noise ratio criterion is employed. After derivation of the optimum filters, the MMSE solution is reviewed. It is shown via matrix manipulations, that both soluti...

An efficient method is derived in this paper to obviate the integral involved in the performance analysis of the minimum mean square error (MMSE) detector for direct-sequence code-division multiple-access (DS/CDMA) systems in fading environments. The new method is shown to significantly reduce the necessary computational load for the performance analysis of the MMSE detector. We then examine th...

This work presents joint minimum mean-square error (MMSE) consensus algorithm and relay selection algorithms for distributed beamforming. We propose joint MMSE consensus relay and selection schemes with a total power constraint and local communications among the relays for a network with cooperating sensors. We also devise greedy relay selection algorithms based on the MMSE consensus approach t...

Interaction Between Prestroke Cognitive Performance and Incident Stroke in Predicting Risk of Dementia To the Editor: Reitz and colleagues examined whether 2 important dementia risk factors—cognitive performance and incident stroke—have an interactive effect on subsequent dementia risk or have only independent effects.1 They reported finding no interaction between incident stroke and prestroke ...

OBJECTIVE The aim of this study is to investigate whether a combination of the Korean version of the mini-mental state examination (K-MMSE) and the Korean dementia screening questionnaire (KDSQ) is better than the use of test alone when differentiating patients with dementia from those without dementia in Korea. METHODS The subjects (patients without dementia, 1120; patients with dementia, 90...
