Abstract There are few studies investigating the short-term effects of Virtual Reality based Exergaming (EG) on motor and cognition simultaneously pursue brain functional activity changes after these interventions in patients with Parkinson’s Disease (PD). The purpose this study was to investigate synergistic therapeutic EG cognitive symptoms PD its possible neuroplasticity. Eligible diagnosis were randomly assigned one two groups: (1) an experimental group, (2) active control Exercise...

Patients with mild cognitive impairment due to Alzheimer’s disease (ADMCI) typically show abnormally high delta (<4 Hz) and low alpha (8–12 rhythms measured from resting-state eyes-closed electroencephalographic (rsEEG) activity. Here, we hypothesized that the abnormalities in rsEEG activity may be greater ADMCI patients than those MCI not AD (noADMCI). Furthermore, they associated diagnostic cerebrospinal fluid (CSF) amyloid–tau biomarkers patients. An international database provided...

Parkinson's disease with dementia (PDD) and Lewy bodies (DLB) are more prevalent in males than females. Furthermore, they typically showed abnormally high delta (< 4 Hz) low alpha (8-10 rhythms from resting-state electroencephalographic (rsEEG) activity. Here, we hypothesized that those abnormalities may depend on the patient's sex. An international database provided clinical-demographic-rsEEG datasets for cognitively unimpaired older (Healthy; N = 49; 24 females), PDD (N 39; 13 DLB 38; 15...

Cognitive impairment (CI) is very common in patients with Parkinson's Disease (PD) and progressively develops on a spectrum from mild cognitive (PD-MCI) to full dementia (PDD). Identification of PD at risk developing decline, therefore, unmet need the clinic manage disease. Previous studies reported that oral microbiota was altered even early stages poor hygiene associated dementia. However, data single modalities are often unable explain complex chronic diseases brain cannot reliably...

Parkinson's disease (PD) is a neurodegenerative that characterized by loss of dopaminergic neurons in the substantia nigra. Mild Cognitive impairment (MCI) and dementia may come along with disease. New indicators are necessary for detecting patients likely to develop dementia. Electroencephalogram (EEG) Delta responses one essential electrophysiological could show cognitive decline. Many research literature showed an increase delta increased load. Furthermore, were decreased MCI Alzheimer...

Pharmacotherapy and thalamic stimulation are the most accepted methods used for treatment of essential tremor (ET). Transcranial direct current (tDCS) is a noninvasive method brain stimulation, especially to treat pain, cerebrovascular disease, depression. tDCS applied cerebellar region has been shown exhibit modulating effect on excitability Purkinje cells cause primary motor cortex inhibition through regulation synaptic dentato-thalamo-cortical excitability. There only 1 trial that studied...

Purpose: The prevalence of sensory disorders (smell and/or taste) in affected patients has shown a high variability 5% to 98% during the COVID-19 outbreak, depending on methodology, country, and study. Loss smell taste occurring cases are now recognized by international scientific community as being among main symptoms disease. This study investigates loss outpatients hospitalized with laboratory-confirmed infection. Methods: Enrolled were positive PCR test for COVID-19. Excluded chronic...

Charles Bonnet Syndrome (CBS) is a rare clinical condition which characterized by complex hallucinations in visually impaired patients. The pathophysiology of this disorder remains largely unknown, and there still no proven treatment for disease. In our study, we aimed to investigate the neural activity through Electroencephalography (EEG) power evaluate effect rivastigmine combination with alpha-lipoic acid on hallucination two CBS patients diabetic retinopathy.EEG data was recorded...

Aim: The purpose of this study is to prepare the Turkish version International Restless Legs Syndrome (RLS) Study Group Rating Scale and investigate its validity reliability. Materials Methods: A total 89 individuals with RLS were included. These subjects divided into two groups: pilot group (n=20) a (n=69). scale was translated adjusted for applied groups. Results: In analysis conducted test factor structure scale, it clearly seen that items collected under factors in accounted 68.19%...

Patients with essential tremor (ET) have an increased prevalence of hearing loss, and depression is a confounding issue for both conditions. We assessed loss in non-depressed ET patients controls using questionnaire audiometric tests.The study included 34 45 volunteers were included. Both groups asked if they had pure tone audiometry, speech recognition threshold, tympanogram, short increment sensitivity index (SISI), decay, otoacoustic emission audiological tests conducted.Seventeen...
