OBJECTIVE: Relationship between masticatory function and cognitive impairment had been suggested but still understudied. We investigated the association between chewing ability and cognitive impairment among the elderly living in a rural region. METHODS: A total of 295 elderly individuals aged ≥70 years in a rural city of Korea participated in a cross-sectional study. Trained nurses conducted interviews and assessed chewing ability using gum that changed color based on chewing performance...

BACKGROUND: Identification of predictive factors on institutionalization provides the basis for the development and application of preadmission assessment. There is a lack of evidence for predictors of institutionalization for older people. AIMS: To examine the effect of predictive factors on institutionalization in home-dwelling 70-year-old people. METHODS: The data were collected in 1991 by the clinical examinations, a postal questionnaire, and an interview from the residents of Turku, Finland, born in 1920 (n = 1032)...

Specific changes in personality profiles may represent early non-cognitive symptoms of Alzheimer's disease (AD). Evaluating the subject's personality changes may add significant clinical information, as well as help to better understand the interaction between personality change, cognitive decline, and cerebral pathology. With this study we aimed to describe the relationship between personality changes and cerebrospinal fluid (CSF) markers of AD pathology at early clinical stages of the disease. One hundred and ten subjects, of whom 66 cognitively impaired patients (57 with mild cognitive impairment (MCI), and 9 with mild dementia) and 44 healthy controls, had neuropsychological examination as well as lumbar puncture to determine concentrations of CSF biomarkers of AD pathology (amyloid beta1-42 (Aβ1-42), phosphorylated tau (ptau-181), and total-tau (tau))...

Objective: Late-life depression (LLD) is associated with development of different types of dementia. Identification of LLD patients, who will develop cognitive decline, i.e., the early stage of dementia would help to implement interventions earlier. The purpose of this study was to assess whether structural brain magnetic resonance imaging (MRI) in LLD patients can predict mild cognitive impairment (MCI) or dementia 1 year prior to the diagnosis. Methods: LLD patients underwent brain MRI at baseline and repeated clinical assessment after 1-year...

BACKGROUND: Accumulating evidence points to the superiority of the MoCA over the MMSE as a cognitive screening tool. To facilitate the transition from the MMSE to the MoCA in clinical and research settings, authors have developed MMSE-MoCA conversion tables. However, it is unknown whether a conversion table generated from Alzheimer's disease (AD) patients would apply to patients with other dementia subtypes like vascular dementia or frontotemporal dementia. Furthermore, the reliability and accuracy of MMSE-MoCA conversion tables has not been properly evaluated...

Genome-wide association studies and meta-analyses implicated that increased risk of developing Alzheimer's diseases (AD) has been associated with the ABCA7, APOE, BIN1, CASS4, CD2AP, CD33, CELF1, CLU, CR1, DSG2, EPHA1, FERMT2, HLA-DRB1, HLA-DRB4, INPP5D, MEF2C, MS4A4A, MS4A4E, MS4A6E, NME8, PICALM, PLD3, PTK2B, RIN3, SLC24A4, SORL1, and ZCWPW1 genes. In this study, we assessed whether single nucleotide polymorphisms (SNPs) within these 27 AD-associatedgenes are linked with cognitive aging independently and/or through complex interactions in an older Taiwanese population...

PURPOSE: The activity of the glymphatic system is impaired in animal models of Alzheimer's disease (AD). We evaluated the activity of the human glymphatic system in cases of AD with a diffusion-based technique called diffusion tensor image analysis along the perivascular space (DTI-ALPS). MATERIALS AND METHODS: Diffusion tensor images were acquired to calculate diffusivities in the x, y, and z axes of the plane of the lateral ventricle body in 31 patients. We evaluated the diffusivity along the perivascular spaces as well as projection fibers and association fibers separately, to acquire an index for diffusivity along the perivascular space (ALPS-index) and correlated them with the mini mental state examinations (MMSE) score...

Whether leukoaraiosis burden retards short-term recovery after minor stroke is unclear. We investigated the association between leukoaraiosis and early recovery of neurological function after a first minor ischemic stroke in 217 acute stroke patients (National Institutes of Health Stroke Scale (NIHSS) score ≤5). Leukoaraiosis severity was graded according to the Fazekas scale and categorized into none to mild (0-2; n = 143) or severe (3-6; n = 74) groups. NIHSS and Minimum Mental State Examination (MMSE) were assessed at baseline and at 30 days...

PURPOSE: Previous studies suggest an association between use of anticholinergic drugs in elderly patients and cognitive impairment. However, there are still limited data on the association of anticholinergic drug use and cognitive impairment as well as contribution of individual drugs to anticholinergic load using large, well-documented patient cohorts treated in geriatric units from Europe. METHODS: We investigated 797,440 prescriptions to 89,579 hospitalized patients treated in geriatric units within the GiB-DAT database...

OBJECTIVE: This study investigated whether patients with mild to moderately severe dementia or possible Alzheimer's disease (AD) with Mini-Mental State Exam (MMSE) Baseline scores of 10-24 would improve when treated with near-infrared photobiomodulation (PBM) therapy. BACKGROUND: Animal studies have presented the potential of PBM for AD. Dysregulation of the brain's default mode network (DMN) has been associated with AD, presenting the DMN as an identifiable target for PBM...

OBJECTIVES: The number of patients with insomnia is rapidly increasing as society ages. The influence of insomnia on cognitive, affective, and activities of daily living (ADL) functions has not been fully studied. METHODS: Participants were 142 residents of a local super-aged community who underwent health check-ups provided by the local government. Participants completed cognitive, affective and ADL function tests including the MMSE. We divided participants into two subgroups based on Athens Insomnia Scale (AIS) scores (AIS ≤3 and AIS ≥4) and compared cognitive, affective, and ADL functions by sex and age...

OBJECTIVES: There is limited research in cognition and its relationship to mortality after hip fracture among men compared to women. Therefore, the goals of this study were to: (1) compare men and women who fractured their hip on cognition after hospital discharge, and (2) examine the impact of cognition on the differential risk of 6-month mortality between men and women post fracture.

BACKGROUND: Brain MRI-markers are risk factors of dementia and decline in cognition and daily functioning. It is unknown to what extent the associations of brain MRI-markers with cognition and daily functioning are part of the pathway leading to dementia. We aimed to investigate associations of brain MRI-markers with change in cognition and daily functioning during 15 years of follow-up, including their relation to dementia. DESIGN, SETTING, AND PARTICIPANTS: Four hundred and sixty three stroke-free and non-demented participants from the population-based Rotterdam Study that underwent brain-MRI, yielding brain volumetrics, between 1995 and 1996...

OBJECTIVE: To assess the efficacy of a combination of cognitive training (COG) and repetitive transcranial magnetic stimulation (rTMS), on cognitive performance, locomotor activity, apathy, caregiver burden and dependence of patients with Alzheimer's disease (AD). METHODS: A combination of COG and rTMS was performed in 10 patients with AD (NeuroAD procedure) for a period of 5weeks (one session per day, 5days a week), without maintenance sessions. Patients were evaluated at the end of the treatment (D45) and 6months later (M6) by the Mini Mental State Examination (MMSE), the Alzheimer disease assessment scale - cognitive subscale (ADAS-Cog), various neuropsychological tests and clinical scores specific for locomotor activity, apathy, caregiver burden, and dependence, recorded before the study (baseline)...

BACKGROUND: Aerobic training has some benefits for delaying the onset or progression of Alzheimer's disease (AD). Little is known about the implication of the brain's two main fuels, glucose and ketones (acetoacetate), associated with thesebenefits. OBJECTIVE: To determine whether aerobic exercise training modifies brain energy metabolism in mild AD. METHODS: In this uncontrolled study, ten patients with mild AD participated in a 3-month, individualized, moderate-intensity aerobic training on a treadmill (Walking)...
