In [1], we presented a new multichannel estimation method based on blind MMSE ZF Equalization. The recently proposed method by Tsatsanis et al. [5] corresponds to unbiased MMSE Equalization. We interpret this approach in terms of Two-Sided Linear Prediction (TSLP), also called smoothing by Tong [8]. We establish the links between MMSE, Minimum Output Energy (MOE) and MMSE ZF and we prove equiva...

The Frontal Assessment Battery (FAB) has been proposed as a diagnostic tool for patients with frontal lobe syndrome. Objectives To present the Brazilian version of the FAB and to show preliminary data on the performance of healthy elderly in the battery, correlating with age, education and scores in the Mini- Mental State Examination (MMSE). Methods Forty-eight healthy elderly individuals (...

Lack of insight or impaired awareness of deficits in patients with dementia is a relatively neglected area of study. The aim of this study was to evaluate insight in a group of demented patients with two assessment scales and to assess their relationship with the cognitive level of disease severity. Sixty-nine consecutive patients affected by Alzheimer's disease (n = 37) and vascular dementia (...

Abstract The discovery of the Turbo codes has driven research on the creation of new signal detection concepts that can, in general, be referred to as the Turbo approach. Recently, this approach has made a drastic change in creating signal detection techniques and algorithms such as equalization of inter-symbol interference (ISI) experienced by broadband single carrier signaling over mobile rad...

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 ...

The two-way amplify-and-forward (AF) relaying network consisting of 2M sources with only a single antenna per source and one relay with multiple N antennas at the 2M destinations is investigated in this paper. All sources act as both sources and destinations with a self-interference cancelation process at the 2M destinations. The closed form of the relay amplifying matrix is optimized under the...

OBJECTIVE Two conversion tables between the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) have recently been established for Parkinson's disease (PD). This study aimed to validate them in Korean patients with PD and to evaluate whether they could be influenced by educational level. METHODS A total of 391 patients with PD who undertook both the Korean MMSE and t...

OBJECTIVE To develop the Korean version of the Cognitive Assessment Scale for Stroke Patients (K-CASP) and to evaluate the test reliability and validity of the K-CASP in stroke patients. METHODS The original CASP was translated into Korean, back-translated into English, then reviewed and compared with the original version. Thirty-three stroke patients were assessed independently by two examin...

Objective Post-stroke cognitive impairment often afflicts stroke survivors and is a major obstacle both for cognitive and physical rehabilitation. Stroke risk scores ["Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, Stroke" (CHADS2) and "CHADS2 + creatinine clearance <60 mL/min" (R2CHADS2)] are used to assess the future risk of cardioembolic stroke in patients with atr...

OBJECTIVE There is a need for a cognitive function screening test that can be administered to patients with systemic lupus erythematosus (SLE) in clinic. The objectives of this study were to determine (1) prevalence of cognitive impairment (CI) in SLE by the Montreal Cognitive Assessment (MoCA), Mini Mental State Examination (MMSE), in relation to the Hopkins Verbal Learning Test-Revised (HVLT-...
