Claudio L Bassetti, Panagiotis Bargiotas
Rapid eye movement sleep behavior disorder (RBD) is a brain disorder, characterized by the dream enactment during rapid eye movement (REM) sleep due to a lack of physiologic muscle atonia and increased muscle twitching. Schenk was the first to describe this disorder in 1986; however, few authors reported in the 1970-1980s loss of physiological muscle atonia combined with dream enactment in the course of brainstem disorders and as a consequence of alcoholism and antidepressant treatment. RBD affects less than 1% of the adult population, but can be found in up to 25-50% of neurodegenerative disorders including Parkinson's disease, multisystem atrophy, and dementia with Lewy body...

BACKGROUND: 'Wearing off' refers to the phenomenology of movement disorders in Parkinson's disease (PD) that appears early and is much commoner than generally believed. It may be present in the form of either motor symptoms or non-motor symptoms. AIM: To investigate the utility of wearing-off questionnaire (WOQ-19, Italian version) in the outpatient clinical practice to assess the suitability of different combinations of treatment, in various stages of PD. METHODS: 73 consecutive patients (58% male and 42% female) suffering from PD were recruited through the Santorso Hospital and San Martino Hospital from September 2012 to March 2014...

Cognitive impairment is an important non-motor symptom of Parkinson's disease (PD). The neuronal death in nigrostriatal pathway is the main factor for motor symptoms and recent studies indicate a possible influence in non-motor symptoms as well. The pedunculopontine tegmental nucleus (PPT) and basal ganglia are closely related anatomically and functionally and, since they are affected by neurodegeneration in PD, they might be involved in recognition memory. To investigate this, we promoted an ibotenic acid lesion within the PPT or a rotenone lesion within substantia nigra pars compacta (SNpc) of Wistar rats, followed by 24h of REM sleep deprivation (REMSD)...

Background: Parkinson's disease (PD) is diagnosed on the basis of motor symptoms, but non-motor symptoms (NMS) have high prevalence in PD and often antecede motor symptoms for years and cause severe disability. This study was conducted to determine the prevalence of NMS in patients with PD. Methods: This cross-sectional study was performed in Isfahan, Iran, on patients with PD. The prevalence of NMS was evaluated by the NMS questionnaire, the NMS scale, and Parkinson's disease questionnaire-39 (PDQ-39). The Mini-Mental Status Examination (MMSE) was used for assessing cognition...

Anxiety in Parkinson's disease is a comorbid non-motor symptom that alters the quality of life of patients. Its neuronal substrates and those of l-Dopa treatment are still poorly known. Using different combinations of monoaminergic system lesions in the rat, we addressed the contribution of these systems in the efficacy of l-DOPA on anxiety and on the neuronal activity of basolateral amygdala (BLA), a brain structure involved in anxiety. Anxiety, locomotor activity and motor performance were assessed using the elevated plus maze, the open field and the skinner box, respectively...

Parkinson's disease (PD) is a prevalent movement disorder in the elderly. PD is hallmarked with progressive deterioration of mesencephalic dopaminergic neurons and development of debilitating motor and non-motor clinical symptoms. Klotho protein is the product of an aging-suppressor gene that its overexpression could protect neurons against oxidative injury. This study was undertaken to explore whether exogenous klotho could alleviate injury of nigrostriatal dopaminergic pathway in 6-hydroxydopamine (6-OHDA) rat model of PD...

Olfactory decline is a frequent and early non-motor symptom in Parkinson's disease (PD), which is increasingly used for diagnostic purposes. Another early appearing sign of PD consists in electroencephalographic (EEG) alterations. The combination of olfactory and EEG assessment may improve the identification of patients with early stages of PD. We hypothesized that olfactory capacity would be correlated with EEG alterations and motor and cognitive impairment in PD patients. To the best of our knowledge, the mutual influence of both markers of PD-olfactory decrease and EEG changes-was not studied before...

Parkinson disease (PD) is associated with multiple factors, including iron, which is demonstrated to deposit excessively in PD brains. We detected iron deposition by susceptibility weighted image (SWI) and measured the levels of iron metabolism-related proteins and inflammatory factors in cerebrospinal fluid (CSF) and serum of PD patients and control subjects. Clinical symptoms of PD were evaluated by series of rating scales. Relationships among above factors were analyzed. Results showed that corrected phase (CP) value of substantia nigra (SN) was significantly decreased in PD group compared to control group, hence, SN was the main region with excessive iron deposition...

Parkinson's disease (PD) is a progressive degenerative disorder that leads to disabling motor symptoms and a wide variety of neuropsychiatric symptoms. Apathy is the most common psychiatric disorder in the early stages of untreated PD and can be defined as a hypodopaminergic syndrome, which also includes anxiety and depression. Apathy is also considered the core feature of the parkinsonian triad (apathy, anxiety and depression) of behavioural non-motor signs, including a motivational deficit. Moreover, apathy is recognised as a distinct chronic neuropsychiatric behavioural disorder based on specific diagnostic criteria...

Parkinson's disease (PD) is a neurodegenerative disorder affecting motor and cognitive abilities. There is no cure for PD, therefore identifying safe therapies to alleviate symptoms remains a priority. This meta-analysis quantified the effectiveness of repetitive transcranial magnetic stimulation (rTMS) and transcranial electrical stimulation (TES) to improve motor and cognitive dysfunction in PD. PubMed, EMBASE, Web of Science, Google Scholar, Scopus, Library of Congress and Cochrane library were searched...

Parkinson's disease (PD) is expressed through motor and non-motor symptoms (NMS) that differ considerably in presence and severity among patients and over time. Furthermore, the progression pattern of the NMS does not necessarily parallel the course of the motor impairment. Gradation of PD according to the motor impairment and burden of NMS is an unmet need for an appropriate management of patients. Areas covered: A review of the studies on clinical gradation methods applied to PD is carried out in this article...

Parkinson's disease (PD) is a movement disorder, mainly affecting population consisting of the aged. PD occurs chiefly due to progressive loss of dopaminergic neurons in nigrostriatal pathway. Largely, PD patients suffer from non-motor symptoms, such as depression, anxiety, fatigue, and sleep disorders, that needs further investigation and addressing during PD research. Depression in PD is a predominant and complex symptom, and its pathology exists extrinsic to the nigrostriatal system. This disease can  ultimately be managed by a combination of regular physiotherapy and proper medication...

BACKGROUND: Constipation is a common non-motor symptom of Parkinson's disease. Deposition of α-synuclein inclusions that spread from the gut to the substantia nigra through the vagus nerve has been recently speculated as a pre-motor and early stage of Parkinson's disease. OBJECTIVE: To investigate whether constipation is associated with dopaminergic pathology at DAT SPECT in early de novo (untreated) Parkinson's disease patients. Our hypothesis is that constipation is associated with other signs of pre-motor Parkinson's disease and independent of DAT dopaminergic pathology...

The clinical definition of Parkinson's disease (PD) is based on cardinal motor features including bradykinesia as well as an additional symptom of tremor, postural instability, or rigidity. Evidence from neuropathological, imaging, and clinical research suggests a premotor, early phase of PD pathology. Further understanding of the earliest biomarkers of PD is crucial for the development of neuroprotective, disease modifying, cognitive, and psychiatric interventions. Recent research has explored early non-motor markers of PD pathology...

Deep brain stimulation (DBS) is an effective (but non-curative) treatment for some of the motor symptoms and treatment complications associated with dopaminergic agents in Parkinson's disease (PD). DBS can be done relatively safely and is associated with quality of life gains. In most DBS centers, neuropsychological evaluations are performed routinely before surgery, and sometimes after surgery. The purpose of such evaluation is not to decide solely on its results whether or not to offer DBS to a given candidate, but to provide the patient and treatment team with the best available information to make reasonable risk-benefit assessments...
