Kristin A Schuller, Brooke Vaughan, Ian Wright
The elderly who suffer from chronic conditions have an increasingly difficult time accessing health care in rural areas compared with their healthy counterparts who seek and utilize less specialty care. Parkinson disease affects approximately 0.3% to 5% of the elderly population. However, a large portion of that population has difficulty accessing health care. The purpose of this study was to obtain an understanding of the access to care issues for patients with Parkinson disease and review solutions to aid their provision of care...

Transcranial direct current stimulation (tDCS) is increasingly being used to affect the neurological conditions with deficient intracortical synaptic activities (i.e. Parkinson's disease and epilepsy). In addition, it is suggested that the lasting effects of tDCS on corticospinal excitability (CSE) have intracortical origin. This systematic review and meta-analysis aimed to examine whether tDCS has any effect on intracortical circuits. Eleven electronic databases were searched for the studies investigating intracortical changes induced by anodal (a) and cathodal (c) tDCS, in healthy individuals, using two paired-pulse transcranial magnetic stimulation (TMS) paradigms: short-interval intracortical inhibition (SICI) and intracortical facilitation (ICF)...

REVIEW
Jeffrey R Liddell
Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that regulates hundreds of antioxidant genes, and is activated in response to oxidative stress. Given that many neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease and multiple sclerosis are characterised by oxidative stress, Nrf2 is commonly activated in these diseases. Evidence demonstrates that Nrf2 activity is repressed in neurons in vitro, and only cultured astrocytes respond strongly to Nrf2 inducers, leading to the interpretation that Nrf2 signalling is largely restricted to astrocytes...

Histamine H3 receptor (H3R) is associated with several neuropsychological diseases. It is predominantly expressed in the central nervous system as presynaptic receptor, especially in regions associated with cognition and behavior, and is responsible for modulate the synthesis and release of histamine and other neurotransmitters such as acetylcholine, dopamine and serotonin. Therefore, H3R is an important target involved in several CNS disorders, such as narcolepsy, attention deficit hyperactivity disorder and schizophrenia...

INTRODUCTION: Impulse control disorders (ICDs) are psychiatric disorders characterized by the failure to resist an impulse or by the temptation to perform an act that is harmful to oneself or to others. METHODS: ICDs, including pathological gambling, hypersexuality, compulsive eating and shopping, can occur as a complication of Parkinson's disease (PD) together with other behavioral disorders, including dopamine dysregulation syndrome. This review is based on a literature search updated to May 2017, focusing on the epidemiology, clinical features, and therapeutic options of ICDs associated with PD...

Parkinson's disease psychosis (PDP) may develop in up to 60% of Parkinson's patients and is associated with increased morbidity and mortality. It also correlates with depression and dementia, and can contribute to caregiver stress and burnout. Pimavanserin is the first FDA approved drug for the treatment of hallucinations and delusions associated with PDP. Areas covered: For this review, a MEDLINE literature search (via PubMed) and information provided by ACADIA Pharmaceuticals were used. References of our search results were screened for additional studies...

The aim of this study was to perform a systematic review of the effects of 1-month paliperidone palmitate (PP1M) for the treatment of schizophrenia and related psychotic disorders in terms of outcomes reported in real-world evidence studies. A systematic review of real-world randomized and nonrandomized studies with PP1M was performed and is reported according to PRISMA guidelines. Comparative effectiveness data with oral antipsychotics indicate that PP1M has a lower likelihood of relapse-related events, including rehospitalization, and these differences are clinically relevant...

Parkinson's disease (PD) is a common neurodegenerative disorder, with ageing being a major risk factor. Accordingly, estimates predict an increasing number of PD patients due to our expanding life span. Consequently, developing a true disease-modifying therapy is necessary. In this regard, monogenic PD offers a suitable means for determining pathogenesis. Among monogenic forms of PD, mitochondrial dysfunction may be a major cause and is also likely to be involved in sporadic PD. Thus, mitochondrial impairment may be a common pathway...

BACKGROUND: In recent years human phospholipase D enzymes (PLD1 and PLD2 isozymes) have emerged as drug targets for various diseases such as cardiovascular disease, cancer, infectious diseases and neurodegenerative conditions such as Alzheimer's and Parkinson's disease. The interest in PLD as a drug target is due to the fact that PLD enzymes belong to a superfamily of phospholipases that are essential to intracellular and extracellular signaling. Many bioactive lipid signaling molecules are generated by these enzymes including phosphatidic and lysophosphatidic acid, arachidonic acid, and diacylglycerol (DAG)...

PURPOSE: A variety of fixed-dose combination products is used in the therapy of Parkinson Disease. However, to date a proper analytical method applicable for comparative screening of different antiparkinson products was not available. The objective of the present work was thus to develop and validate an analytical method for the simultaneous quantification of levodopa, carbidopa, benserazide and entacapone. The method should be applicable for quantifying samples from drug release experiments with marketed products and prototype formulations performed under compendial and biorelevant test conditions...

We aimed to comprehensively analyse the safety and efficiency of rotigotine for treating Parkinson's disease (PD). We conducted systematic literature searches of Cochrane library, PubMed and Embase databases up to April 2016, with 'Rotigotine', 'Parkinson Disease ' and 'Parkinson's disease' as key searching terms. Outcomes, including Unified Parkinson's Disease Rating Scale (UPDRS) Part III and Part II scores, 'off' time, adverse events (AEs), serious AEs and discontinuation because of AEs, were compared between rotigotine and placebo groups under a fixed or random effect model...

PURPOSE OF REVIEW: The aims of the study were to review recent advances in molecular imaging in the Lewy body dementias (LBD) and determine if these may support the clinical but contested temporal profile distinction between Parkinson disease (PD) with dementia (PDD) versus dementia with Lewy bodies (DLB). RECENT FINDINGS: There do not appear to be major regional cerebral metabolic or neurotransmitter distinctions between PDD and DLB. However, recent studies highlight the relative discriminating roles of Alzheimer proteinopathies...

The cerebrospinal fluid (CSF) signature of reduced amyloid beta 1-42 (Aβ42), elevated total tau (t-tau), and phosphorylated tau181 (p-tau) is important for the early diagnosis of Alzheimer's disease (AD). Aβ42, t-tau, and p-tau have been reported in numerous studies to contribute to predicting cognitive impairment in Parkinson's disease (PDCI). However, no consistent conclusion can be drawn so far. Literatures regarding Aβ42, t-tau, and p-tau in CSF were systematically reviewed, and a meta-analysis was thus performed to evaluate the changes of these biomarkers in PDCI patients, including PD with mild cognitive impairment (PDMCI) and PD dementia (PDD) patients, relative to PD with normal cognition (PDNC) patients...

Parkinson's disease is a progressive neurodegenerative disorder. Although both genetic and environmental factors are implicated in the development of Parkinson's disease, the cause of the disease is still unclear. So far conventional treatments to Parkinson's are symptomatic relief and focused mainly on motor symptoms. Chinese herbal medicine has been used to treat many conditions in China, Korea, Japan, and many Southeast Asian countries for 1000 years. During past a few decades, Chinese herbal medicine has gained wider and increasing acceptance within both public and medical profession due to its effectiveness on many conditions in western countries...

Chinese herbal medicine has been used to treat a wide variety of neurological disorders including stroke, Alzheimer's disease, and Parkinson's disease. However, its mechanism behind the effectiveness remains unclear. Recently, molecular imaging technology has been applied for this purpose, since it can assess the cellular or molecular function in a living subject by using specific imaging probes and/or radioactive tracers, which enable efficient analysis and monitoring the therapeutic response repetitively...

Pain affects many people with Parkinson's disease (PD) and diminishes their quality of life. Different types of pain have been described, but their related pathophysiological mechanisms remain unclear. The aim of this chapter is to provide movement disorders specialists an update about the pathophysiology of pain and a practical guide for the management of pain syndromes in clinical practice. This chapter reviews current knowledge on the pathophysiological mechanisms of sensory changes and pain in PD, as well as assessment and treatment procedures to manage these symptoms...

The use of complementary and alternative medicine (CAM) therapy in nonmotor symptoms (NMS) for Parkinson disease (PD) is growing worldwide. Well-performed, systematic evidence-based research is largely lacking in this area and many studies include various forms of CAM with small patient numbers and a lack of standardization of the approaches studied. Taichi, Qigong, dance, yoga, mindfulness, acupuncture, and other CAM therapies are reviewed and there is some evidence for the following: Taichi in sleep and PDQ39; dance in cognition, apathy, and a mild trend to improved fatigue; yoga in PDQ39; and acupuncture in depression, PDQ39, and sleep...

To date, no guidelines exist for the screening, evaluation, and management of nutritional status in PD. Dozens of studies demonstrate an association between diet in adulthood with subsequent risk of developing PD. Individuals with PD are at increased risk of malnutrition due to the increased metabolic demands and disease pathophysiology. Risk of malnutrition is further complicated by anosmia, swallowing difficulties, constipation, and drug-nutrient interactions. An emerging body of evidence suggests that the intestinal tract is affected early in the disease, creating therapeutic opportunities for early intervention...
