BACKGROUND: In Germany, about 15 million people are suffering from hearing loss (HL), whereas only 16 % are using hearing aids. Untreated hearing loss may lead to severe complications (e. g. social isolation, depression, progress of dementia). An early and widespread screening, beginning at the age of 50, is meant to improve this shortage in medical care. By this study, the Mini-Audio-Test (MAT), a six-question and three-step answers containing questionnaire on subjective HL, should be verified on a normal collective of subjects (sensitivity (Se), specificity (Sp), positive predictive value (Ppv))...

Objective: To establish a cut score for the Montreal Cognitive Assessment (MoCA) that distinguishes mild cognitive impairment (MCI) from normal cognition (NC) in a community-based African American (AA) sample. Methods: A total of 135 AA participants, from a larger aging study, diagnosed MCI (n = 90) or NC (n = 45) via consensus diagnosis using clinical history, Clinical Dementia Rating score, and comprehensive neuropsychological testing. Logistic regression models utilized sex, education, age, and MoCA score to predict MCI versus NC...

Radiation therapy and concomitant temozolomide chemotherapy are commonly used in treatment of brain tumors, but they may also result in behavioral impairments such as anxiety and cognitive deficit. The present study sought to investigate the effect of fluoxetine on the behavioral impairments caused by radiation and temozolomide treatment. C57BL/6J mice were subjected to a single cranial radiation followed by 6-week cyclic temozolomide administration, and then treated with chronic administration of fluoxetine...

PURPOSE OF REVIEW: The funduscopic examination can be a technically difficult, and often omitted, portion of the neurologic examination, despite its great potential to influence patient care. RECENT FINDINGS: Medical practitioners are often first taught to examine the ocular fundus using a direct ophthalmoscope, however, this skill requires frequent practice. Nonmydriatic tabletop and portable fundus photography and even smartphone-based photography offer alternative and practical means for approaching examination of the ocular fundus...

BACKGROUND: Observational studies in Asia show that dietary intake of soy isoflavones had a significant inverse association with coronary heart disease (CHD). A recent randomized controlled trial (RCT) of soy isoflavones on atherosclerosis in the US, however, failed to show their benefit. The discrepancy may be due to the much lower prevalence of S-equol producers in Westerners: Only 20-30% of Westerners produce S-equol in contrast to 50-70% in Asians. S-equol is a metabolite of dietary soy isoflavone daidzein by gut microbiome and possesses the most anti-atherogenic properties among all isoflavones...

The orphan nuclear receptor Nurr1 (also known as NR4A2) is critical for the development and maintenance of midbrain dopaminergic neurons, and is associated with Parkinson's disease. However, an association between Nurr1 and Alzheimer's disease (AD)-related pathology has not previously been reported. Here, we provide evidence that Nurr1 is expressed in a neuron-specific manner in AD-related brain regions; specifically, it is selectively expressed in glutamatergic neurons in the subiculum and the cortex of both normal and AD brains...

AIM: Most patients with dementia frequently encounter various problems in their daily lives. Those troubles embarrass both the patients and their families, and cause problems for society. However, there have been few scientific reports on the difficulties in the daily life of patients with dementia. Therefore, we tried to clarify the frequency and characteristics of troubles experienced by patients with dementia. METHODS: Seven medical centers treating dementia patients in Okayama Prefecture, Japan, participated in this survey...

Mitochondria play a key role in the maintenance of neuronal function by continuously providing energy. Here, we will give a detailed review about the recent developments in regards to dynamin-related protein 1 (Drp1) induced unbalanced mitochondrial dynamics, excessive mitochondrial division, and neuronal injury in neural system dysfunctions and neurodegenerative diseases, including the Drp1 knockout induced mice embryonic death, the dysfunction of the Drp1-dependent mitochondrial division induced neuronal cell apoptosis and impaired neuronal axonal transportation, the abnormal interaction between Drp1 and amyloid β (Aβ) in Alzheimer's disease (AD), the mutant Huntingtin (Htt) in Huntington's disease (HD), and the Drp1-associated pathogenesis of other neurodegenerative diseases such as Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS)...

BACKGROUND: Cognitive impairment (CI) affects approximately one-third of the patients with early multiple sclerosis (MS) and clinically isolated syndrome (CIS). Little is known about factors predicting CI and progression after initial diagnosis. METHODS: Neuropsychological screening data from baseline and 1-year follow-up of a prospective multicenter cohort study (NationMS) involving 1123 patients with newly diagnosed MS or CIS were analyzed. Employing linear multilevel models, we investigated whether demographic, clinical and conventional MRI markers at baseline were predictive for CI and longitudinal cognitive changes...

According to the cognitive reserve theory, intellectual stimuli acquired during life can prevent against developing cognitive impairment. The underlying cognitive reserve mechanisms were underexplored in low-educated individuals. Because episodic memory impairment due to hippocampal dysfunction is a key feature of Alzheimer's dementia (AD), we sought to look at a possible cognitive reserve mechanism by determining whether few years of education moderated the relationship between the hippocampal volumes and the episodic-memory scores...

The role of the cerebellum in cognitive function has been broadly investigated in the last decades from an anatomical, clinical, and functional point of view and new evidence points toward a significant contribution of the posterior lobes of the cerebellum in cognition in Alzheimer's disease (AD). In the present work we used SUIT-VBM (spatially unbiased infratentorial template, voxel-based morphometry) to perform an analysis of the pattern of cerebellar gray matter (GM) atrophy in amnestic mild cognitive impairment (a-MCI) and AD dementia patients compared to healthy subjects (HS), in order to follow the changes of non-motor features of cerebellar degeneration throughout disease progression...

Categorizing people with late-onset Alzheimer's disease into biologically coherent subgroups is important for personalized medicine. We evaluated data from five studies (total n = 4050, of whom 2431 had genome-wide single-nucleotide polymorphism (SNP) data). We assigned people to cognitively defined subgroups on the basis of relative performance in memory, executive functioning, visuospatial functioning, and language at the time of Alzheimer's disease diagnosis. We compared genotype frequencies for each subgroup to those from cognitively normal elderly controls...

INTRODUCTION: Cognitive dysfunction is common in progressive supranuclear palsy (PSP) but its effect on medical decision-making has not been well studied. To address this gap in the research literature, we compared the medical decision-making capacity of patients with PSP to groups of patients with other neurodegenerative disorders. We also investigated the cognitive correlates of medical decision-making in our PSP sample. METHODS: The sample was composed of 65 participants that belonged to five study groups: 13 with PSP, 13 with PD-MCI, 13 with PDD, 13 with AD, and 13 cognitively healthy controls...
