BACKGROUND: DBS is a surgical method of choice for various movement disorders, especially for Parkinson's disease (PD). Many publications showing improvement in motor symptoms and quality of life have been presented while there is little comprehensive research evaluation of the impact of DBS on mental state and psychiatric side-effects. OBJECT: The purpose of this study was to assess the impact of DBS on mood, drive, anhedonia and psychotic symptoms in the group of PD patients...

Parkinson's disease (PD) patients are at a higher risk of malnutrition. The prevalence has been estimated to 0-24%, while 3%-60% of PD patients are reported to be at risk of malnutrition. To date, there is no clear explanation for malnutrition in these patients. The aim of this study was to determine the prevalence of malnutrition and to analyze factors that influence its appearance. The Mini Nutritional Assessment (MNA) was used to determine normal nutritional status; at risk of malnutrition; and already malnourished status...

OBJECTIVE: To assess body distribution and timing of appearance of rest tremor in Parkinson's disease. METHODS: Information was obtained by a computerized database containing historical information collected at the first visit and data collected during the subsequent follow-up visits. Information on rest tremor developed during the follow-up could be therefore obtained by our own observation in a proportion of patients. RESULTS: Among 289 patients, rest tremor was reported at disease onset in 65...

Objectives This study aimed to examine whether occupational and physical activity (PA) at different ages contribute to Parkinson's disease (PD) risk in a large population-based case-control study in Denmark. Methods We identified 1828 PD patients from the Danish National Hospital Register and recruited 1909 gender and year of birth matched controls from the Danish Central Population Register. Occupational and leisure-time PA were determined from a job exposure matrix based on occupational history and self-reported leisure-time information...

BACKGROUND: Parkinson's Disease (PD) psychosis refers to the spectrum of illusions, formed hallucinations and delusions that occur in PD. Visual hallucinations and illusions are thought to be caused by specific cognitive and higher visual function deficits and patients who develop such symptoms early in the disease course have greater rates of cognitive decline and progression to dementia. To date, no studies have investigated whether such deficits are found prior to the onset of PD psychosis...

BACKGROUND: Impulse control disorders/other compulsive behaviours ('ICD behaviours') occur in Parkinson's disease (PD), but prospective studies are scarce, and prevalence and clinical characteristics of patients are insufficiently defined. OBJECTIVES: To assess the presence of ICD behaviours over a 2-year period, and evaluate patients' clinical characteristics. METHODS: A prospective, non-interventional, multicentre study (ICARUS (Impulse Control disorders And the association of neuRopsychiatric symptoms, cognition and qUality of life in ParkinSon disease); SP0990) in treated Italian PD outpatients...

Advancing age is a well-known risk factor for Parkinson's disease (PD). With population ageing it is expected that the total number of patients with PD onset at oldage increases. Information on the motor but particularly on non-motor phenotype of this late-onset population is lacking. We recruited 24 patients with PD onset at or over 75 years. Each patient was matched with 1 control patient with PD onset between the ages of 40 and 65 and matched for disease duration. Both groups were assessed with the UPDRS, the Non-motor symptoms scale (NMSS) and other scales to assess non-motor symptoms...

Multiple system atrophy (MSA) is a devastating and fatal neurodegenerative disorder. The clinical presentation of this disease is highly variable, with parkinsonism, cerebellar ataxia and autonomic failure being the most common - and often debilitating - symptoms. These symptoms progress rapidly, and patients die from MSA-related complications after 9 years of symptom duration on average. Unfortunately, the course of the disease cannot be improved by drug or surgical treatment. In addition, symptomatic treatment options are currently limited, and therapeutic benefits are often only transient...

BACKGROUND: Vocal fold (VF) immobility is a rare, potentially fatal complication of advanced Parkinson's disease (PD). Previous reports suggest that subthalamic nucleus deep brain stimulation (STN-DBS) may influence laryngeal function, yet the role of STN-DBS on VF immobility remains unexplored. CASE DESCRIPTION: We report a case of a patient with advanced PD and bilateral VF immobility ultimately requiring a tracheostomy. To assess the effects of STN-DBS on vocal cord function and to correlate these effects with peripheral motor symptoms at different stimulation settings, the patient was evaluated before and after initiation of bilateral STN-DBS...

Frontostriatal networks play critical roles in grounding action semantics and syntactic skills. Indeed, their atrophy distinctively disrupts both domains, as observed in patients with Huntington's disease (HD) and Parkinson's disease, even during early disease stages. However, frontostriatal degeneration in these conditions may begin up to 15 years before the onset of clinical symptoms, opening avenues for pre-clinical detection via sensitive tasks. Such a mission is particularly critical in HD, given that patients' children have 50% chances of inheriting the disease...

Due to the limited number of MAOs inhibitors in the clinic and several research efforts are aimed at the discovery of novel MAOs inhibitors. At present, high specificity and a reversible mode of inhibition of MAO-A/B are cited as desirable traits in drug discovery process. This will help to reduce the probability of causing target disruption and may increase the duration of action. Most of the existing MAO inhibitors lead to side effects due to lack of affinity and selectivity. Therefore, there is an urgent need to design novel, potent, reversible and selective inhibitors for MAO-A/B...

BACKGROUND: While oxidative stress (OS) may be one of the crucial factors determining the initiation and progression of Parkinson's disease (PD), its correlation with gray matter (GM) atrophy is not known. AIMS: To determine the GM volume (GMV) changes using voxel-based morphometry (VBM) and correlation with OS marker serum malondialdehyde (MDA) in PD. MATERIALS AND METHODS: Seventy-two patients with PD were clinically evaluated and underwent magnetic resonance imaging (MRI) on a 3T MRI scanner using a 32-channel head coil...

Since the 1960s many substance classes have been introduced for treatment of idiopathic Parkinson's disease. The most important and effective medication is levodopa (L-dopa) always in combination with a decarboxylase inhibitor. In addition, dopamine agonists, monoamine oxidase B (MAO-B) inhibitors, catechol-o-methyltransferase (COMT) inhibitors, N‑methyl-D-aspartate (NMDA) antagonists and very rarely anticholinergics are administered depending on the motor symptoms, age and a multitude of other factors. Fortunately, within the substance classes there are various preparations, which also have different effects...

Degeneration of several brainstem nuclei has been long related to motor and non-motor symptoms (NMSs) of Parkinson's disease (PD). Nevertheless, due to technical issues, there are only a few studies that correlate that association. Brainstem auditory-evoked potential (BAEP) and vestibular-evoked myogenic potential (VEMP) responses represent a valuable tool for brainstem assessment. Here, we investigated the abnormalities of BAEPs, ocular VEMPs (oVEMPs), and cervical VEMPs (cVEMPs) in patients with PD and its correlation to the motor and NMSs...

OBJECTIVES: Impulse control disorder (ICD) is a common adverse effect in patients with Parkinson disease who receive dopamine agonists; however, other factors are involved in its manifestations. To study the frequency and factors involved in the development of this adverse effect in a Latin American population, we conducted a cross-sectional multicenter study. METHODS: Two hundred fifty-five patients in 3 Latin American centers were evaluated by examination and application of scales (Unified Parkinson's Disease Rating Scale, Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale, Hoehn and Yahr, Clinical Impression of Severity Index for Parkinson's Disease)...

The caregiver-care receiver relationship (mutuality) in Parkinson's disease (PD) and its association with motor and non-motors symptoms, health-related quality of life (HRQoL), and caregiver burden have not fully been investigated. The aim of our study was to explore if (1) the level of mutuality perceived by PD-patients and PD-partners differs, (2) different factors are associated with perceived mutuality by PD-patients and PD-partners, and (3) mutuality is associated with PD-patients health-related quality of life (HRQoL) and caregiver burden...

Parkinson's disease (PD) is a neurodegenerative disease with progressive loss of mesencephalic dopaminergic neurons of the substantia nigra and with multiple incapacitating motor and non-motor symptoms. Troxerutin is a natural bioflavonoid with nephro- and hepato-protective, antioxidant, and anti-inflammatory properties. In this study, we evaluated its possible neuroprotective effect in 6-hydroxydopamine (6-OHDA) rat model of PD. Intrastriatal 6-OHDA-lesioned rats were pretreated with troxerutin at a dose of 150mg/kg/day for 1 week...

The year 2017 marks the 30th anniversary of the birth of modern deep brain stimulation (DBS), which was introduced by Benabid, Pollak et al. in 1987, initially targeting the motor thalamus to treat tremor, and subsequently targeting the subthalamic nucleus (STN) for treatment of symptoms of advanced Parkinson's disease (PD). STN DBS is undoubtedly "the most important discovery since levodopa", as stated by David Marsden in 1994. In 2014, The Lasker- DeBakey Clinical Medical Research Award to "honor two scientists who developed deep brain stimulation of the subthalamic nucleus", was bestowed upon Benabid and DeLong...

Differentiating Parkinson's disease and atypical parkinsonism on clinical parameters is challenging, especially in early disease courses. This is due to large overlap in symptoms and because the so called red flags, i.e. symptoms indicating atypical parkinsonism, have not (fully) developed. Brain MRI can aid to improve the accuracy and confidence about the diagnosis. The main purpose of brain MRI is to assess cerebrovascular damage, and to exclude other possible - and sometimes treatable - causes of parkinsonism, such as normal pressure hydrocephalus...

Parkinson's disease (PD) is a neurodegenerative condition, which compromises the motor functions and causes the alteration of some executive brain functions. The presence of changes in cognitive symptoms in PD could be due to the procedure of deep brain stimulation (DBS). We searched in several databases for studies that compared performance in executive function tests before and after the DBS procedure in PE and then performed a meta-analysis. After the initial search, there were 15 articles that specifically evaluated the functions of verbal fluency, working memory, cognitive flexibility, abstract thinking, and inhibition...
