This paper first proposes a computationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach employs a convenient representation of the discretemultipath fading channel based on the Karhunen-Loeve (KL) orthogonal expansion and findsMMSE estimates of the uncorrelated KL se...

OBJECTIVES To develop a 10-minute cognitive screening tool (Montreal Cognitive Assessment, MoCA) to assist first-line physicians in detection of mild cognitive impairment (MCI), a clinical state that often progresses to dementia. DESIGN Validation study. SETTING A community clinic and an academic center. PARTICIPANTS Ninety-four patients meeting MCI clinical criteria supported by psychome...

BACKGROUND Brief cognitive screening measures are valuable tools for both research and clinical applications. The most widely used instrument, the Mini-Mental State Examination (MMSE), is limited in that it must be administered face-to-face, cannot be used in participants with visual or motor impairments, and is protected by copyright. Screening instruments such as the Telephone Interview for C...

Abstract This study aimed to verify the psychometric properties of Dysexecutive Questionnaire (DEX) through exploratory factor analysis (EFA), evidence reliability, and convergent validity, in a sample neurologically preserved older adults. Participants were 345 adults who answered, addition DEX, sociodemographic clinical questionnaire, Mini-Mental State Examination (MMSE), two verbal fluency t...

Aim. This study sought to establish the discriminant validity of a rapid cognitive screen, that is, the National Institute of Neurological Disease and Stroke-Canadian Stroke Network (NINDS-CSN) 5-minute protocol, and compare its discriminant validity to the Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) in detecting cognitive impairment (CI) in PD patients. Method...

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 collected on a s...

To assess the influence of education on the performance of Chinese version of Montreal cognitive assessment (C-MoCA) in relation to the mini-mental state examination (MMSE) in detecting amnesic mild cognitive impairment (aMCI) among rural-dwelling older people C-MoCA and MMSE was administered and diagnostic interviews were conducted among community-dwelling elderly in two villages in Beijing. T...

OBJECTIVE To derive population norms on the Malayalam adaptation of Addenbrooke's Cognitive Examination (M-ACE) and the inclusive Malayalam mini mental state examination (M-MMSE). MATERIALS AND METHODS Education-stratified norms were obtained on randomly selected cognitively unimpaired community elders (n = 519). RESULTS Valid data on norms was available on 488 subjects (age 68.5 +/- 7.1 an...

INTRODUCTION The life expectancy of individuals with Chronic Kidney Disease (CKD) on hemodialysis has increased, however, with over years in treatment, there is impairment of cognitive function that affect adherence to therapy and dialysis. OBJECTIVE To evaluate the cognitive ability of individuals on hemodialysis through the Mini Mental State Examination (MMSE) and the relation to sociodemog...
