Metaproteogenomic analysis of saliva samples from Parkinson's disease patients with cognitive impairment.

Cognitive impairment (CI) is very common in patients with Parkinson's Disease (PD) and progressively develops on a spectrum from mild cognitive impairment (PD-MCI) to full dementia (PDD). Identification of PD patients at risk of developing cognitive decline, therefore, is unmet need in the clinic to manage the disease. Previous studies reported that oral microbiota of PD patients was altered even at early stages and poor oral hygiene is associated with dementia.

Re-evaluation of the symptoms of Hirayama disease through anatomical perspective.

Hirayama disease is a rare disease of the anterior horn motor neuron caused by compression of the cervical spinal cord when the neck is flexed. Cervical myelopathy may accompany the disease. It is characterized by symmetrical or asymmetrical muscle weakness and atrophy of muscles innervated by lower cervical and upper thoracic motor neurons.

Axillary Microbiota Is Associated with Cognitive Impairment in Parkinson's Disease Patients.

Cognitive impairment (CI) is among the most common non-motor symptoms of Parkinson's disease (PD), with a substantially negative impact on patient management and outcome. The development and progression of CI exhibits high interindividual variability, which requires better diagnostic and monitoring strategies. PD patients often display sweating disorders resulting from autonomic dysfunction, which has been associated with CI.

The Multifactorial Role of Pre-supplementary Motor Area Stimulation in the Freezing of Gait: An Alternative Strategy to the Classical Drug-Target Approach.

Introduction: The pre-supplementary motor area (Pre-SMA) plays a pivotal role in the control of voluntary motor control and freezing of gait (FOG) pathophysiological mechanism. Here, we aimed to modulate if the pre-SMA would have beneficial effects on motor and behavioural outcomes in freezing of gait. To test this hypothesis, we examined the left pre-SMA stimulating effect of repetitive Transcranial Magnetic Stimulation (rTMS) on motor, cognitive and behavioural parameters in Parkinson's patients with FOG.

The correlation of non-motor symptoms and sleep on balance in Parkinson's disease patients with normal cognition and mild cognitive impairment.

Background: Parkinson's disease (PD) is characterized by non-motor symptoms (NMS) as well as by motor symptoms. Together with the impairment of cognitive functions, NMS and sleep also affect motor symptoms negatively. The aim of our study is to examine the correlation of NMS and sleep on balance in PD patients with normal cognition (PD-NC) and with mild cognitive impairment (PD-MCI).

Olfactory and Gustatory Dysfunctions in COVID-19 Patients: From a Different Perspective.

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

Correlation between alpha activity and neuropsychometric tests in Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disease that leads to memory impairment and executive and visuospatial dysfunction as the disease progresses. Alpha activity on EEG has been related to cognition in previous studies. We aimed to investigate the correlation between alpha activity and neuropsychometric tests (NPTs) in PD patients.

Abnormalities in auditory and visual cognitive processes are differentiated with theta responses in patients with Parkinson's disease with and without dementia.

The research on the abnormalities of event-related oscillations in Parkinson's disease (PD) was mostly studied with cognitively normal patients. The present study aims to show the adverse effects of cognitive decline in PD patients via the EEG-Brain Oscillations approach by comparing the electrophysiological responses in two modalities, i.e.

The Relationship Between Pain, and Freezing of Gait and Falls in Parkinson's Disease.

Introduction: To investigate the relationship between pain, freezing of gait (FOG) and falls in Parkinson's Disease (PD).

Methods: The study included 110 PD patients. The Unified PD Rating Scale (UPDRS) and Hoehn and Yahr Scale were used to evaluate disease severity.

Preliminary findings on the role of high-frequency (5Hz) rTMS stimulation on M1 and pre-SMA regions in Parkinson's disease.

It has been already shown that the motor symptoms of the Parkinson's Disease (PD) have been improved with high frequency rTMS although there is no consensus on the most suitable target brain localization for a maximal therapeutic efficacy. Here, we aimed to compare the therapeutic effect of high frequency (5Hz) rTMS stimulation on primary motor cortex (M1) and pre-supplementary (pre SMA) regions in patients with PD who were still on pharmacological treatment. The study included right-hand dominant16 patients with PD (5 females, 11 males) with demographically and clinically similar characteristics which were randomly assigned to group 1 (n=8) and group 2 (n=8) and received left M1 and the left pre-SMA rTMS procedure, respectively.

Accelerated long-term forgetting after amygdalohippocampectomy in temporal lobe epilepsy.

Aim Of The Study: Temporal lobe epilepsy (TLE) has been associated with the phenomenon of accelerated long-term forgetting (ALF). In this study, we aimed to demonstrate the effect of surgery on the ALF phenomena thus contributing to potential explanation of the causal mechanism.

Materials And Methods: We evaluated 51 patients with TLE related to hippocampal sclerosis who had amygdalohippocampectomy and had remained seizure-free after surgery.

Restless Legs Syndrome in Aircrew.

Restless legs syndrome (RLS) is characterized by an uncomfortable sensation on the legs, which causes the urge to move the legs. The main cause is unknown but there are many risk factors, including geographical properties and high altitude. Our objective was to explore the frequency of RLS in aircrew.

The therapeutic effect of deep brain stimulation on olfactory functions and clinical scores in Parkinson's disease.

Deep brain stimulation (DBS) is still a highly effective treatment option that significantly improves motor function in advanced PD. Moreover, previous findings have shown that Olfactory dysfunction (OD) has been found in a majority of patients with Parkinson's Disease (PD). Despite this, the effect of DBS on the olfactory function is not fully understood.

Anti-Ri-associated paraneoplastic neurological syndrome: Initial symptom of breast cancer with HER2 overexpression and treatment by dual HER2 blockade.

Paraneoplastic neurological syndrome is associated with anti-Ri antibodies, which are typically present with opsoclonus-myoclonus-ataxia. Human epidermal growth factor receptor 2 (HER2) overexpression is present in 15%-25% of breast cancer and is associated with poor prognosis. There are a few reports of paraneoplastic neurological syndrome associated with HER2-positive breast cancer in the literature, of which most are anti-Yo-associated paraneoplastic neurological syndrome.

The Brain Protective Effect of rTMS (Repetitive Transcranial Magnetic Stimulation) in Depression: A Mini-Review in Animal Studies.

There are rapidly replicating human data suggesting the therapeutic and neurorestorative role of repetitive transcranial magnetic stimulation (rTMS) in clinical depression. However there are only limited experimental studies in the literature and the neurobiological mechanisms of the technique are still unclear. Studies have suggested that modulating of either excitatory or inhibitory neural circuitry may be responsible for the mechanism of action of rTMS while it is still unclear whether rTMS exerts a neuroprotective effect.
