parkinson’s disease (pd) is a progressive neurological disorder characterized by tremor, rigidity, and slowness of movements. specific changes associated with various pathological attacks in parkinson’s disease can be indicated in causality interactions of the brain network from resting state fmri data. in this paper, we aimed to reveal the network architecture of the directed influence brain n...

The management of early Parkinson’s disease (PD) involves the treatment of motor symptoms, and, increasingly, nonmotor symptoms. Given the fast pace of clinical research in PD, clinicians are faced with the challenge of integrating the latest findings into the ongoing care of individual PD patients. Part 1 of this 2-part article reviews efficacy and safety data for the newest PD treatment optio...

abstractparkinson’s disease (pd) is a neuropathological and debilitating disorder involving the degeneration of mesencephalic dopaminergic neurons. neuroprotective effect of hesperetin has already been reported, therefore, this study examined whether the administration of this flavonoid would attenuate behavioral abnormalities in an experimental model of pd in rat. for this purpose, unilateral ...

Parkinson’s disease (PD) is a prevalent neurodegenerative movement disorder whose occurrence crosses geographic, racial and social boundaries affecting 1-2% of the population above the age of 65 (Dorsey et al., 2007). Clinically, the disease is attended by a constellation of motoric deficits that progressively worsen with age, which ultimately leads to near total immobility. Although pathologic...

Objective: Parkinson's disease (PD) is one of the most common neurodegenerative disorders which is characterized by tremor, rigidity, bradykinesia and postural disturbances. Studies indicate that grape juice and exercise may have beneficial effects on neurodegenerative disorders. Therefore, in the present study, we evaluated the effects of red grape juice (GJ) together with treadmill running on...

background: parkinson’s disease (pd) is a progressive neurodegenerative disorder causing motor and non‑motor symptoms. the latter are common and include autonomic dysfunction, cognitive impairment, and sleep difficulties. many of the non‑motor aspects of pd such as sleep disturbance are more common and significantly affect the day‑to‑day activities of patients and their quality of life. the mos...

BACKGROUND More than 220 million people worldwide are chronically infected with schistosomes, causing severe disease or even death. The major pathological damage occurring in schistosomiasis is attributable to the granulomatous inflammatory response and liver fibrosis induced by schistosome eggs. The inflammatory response is tightly controlled and parallels immunosuppressive regulation, constan...

normal 0 false false false en-us x-none ar-sa background: vitamin d insufficiency and serum calcium disturbance have been reported to be more common in parkinson’s disease (pd) patients than in healthy control subjects, which may be due to a chronic disease or reduced mobility contributes to these relatively disturbances. because of the high-vitamin d insufficiency in our population, we aimed t...

   Objectives: The present study aimed at investigating the relationship between Dysphonia Severity Index (DSI) and disease speech and voice severity of Parkinson disease (PD) patients. Method. This study was a cross-sectional ones, carried out on 45 PD patients with the age range of 50 to 75 years, who were randomly selected. The Hoehn and Yahr Scale (H.Y Scale) was employed to measure the le...

The clinical diagnostic criteria of Parkinson's disease (PD) have limitations in detecting the disease at early stage and in differentiating heterogeneous clinical progression. The lack of reliable biomarker(s) for early diagnosis and prediction of prognosis is a major hurdle to achieve optimal clinical care of patients and efficient design of clinical trials for disease-modifying therapeutics....
