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...

Parkinson’s disease is the second most common age associated neuron degenerative disorder in developed societies. With the prevalence ranging from 41 per 100000 in the fourth decade of life to over 1900 per 100000 in people over 80 years of age.it characterized clinically by resting tremor, slowness of movement, rigidity and postural instability in the result of progressive loss of dopami...

parkinson's disease (pd) is a very common neurodegenerative disease among the elderly population. current treatments for parkinson’s disease are based on symptom therapy but not the underlying cause of the disease. this disorder is caused neuronal death which triggers the activation of resident glial cells. this situation leads to neuroinflammation in the central nervous system. activated ...

background & aim: parkinson's disease (pd) can be created with loss of dopaminergic substantial nigra neurons which is widely associated with oxidative stress and reduced glutathione (gsh), as the most important and abundant thiol in tissues and one of the antioxidant defense, is one of the earliest biochemical events related to parkinson's and consumption of antioxidants has a protec...

background: there is no documented demographical study on iranian parkinson's disease (pd) patients, so this study was conducted to identify demographic information about patients with pd in iran, and to explore demographical differences between pd patients in iran and other countries. methods: we reviewed medical records of 1656 patients diagnosed with pd, who referred from all parts of iran t...

background and objectives: parkinson's disease (pd) is a common neuropathologic disorder that is caused by degeneration of dopaminergic neurons of dense part of nigra. oxidative stress has been found in the pathophysiology of pd. since α-pinene has strong anti-oxidant effects, the purpose of this research was to study its effects on movement disorders and memory and lipid peroxidation in p...

background & aim:parkinson's disease (pd) is a kind of disorder in the nervous system, which is characterized with multiple movement disorders. factors such as oxidative stress are the most important causes for the degeneration of dopaminergic neurons in the substantia nigra and occurrence of parkinson's disease. thus, medications that have antioxidant functions could be an interestin...

background: patients with parkinson's disease (pd) have different cognitive impairments.the goal of this study is the analysis of these changes in the mentioned patients.a cross-sectional study was performed on 87 patients with pd. patients were given a questionnaire to gather data about their medical and living statuses. to assess cognitive assessment, scopa-cog (scales for outcome in parkinso...

after alzheimer's disease, parkinson's disease is the most common nerve-damaging disease. parkinson's is a progressive and chronic disease where cells secrete dopamine-cut black flesh and in the absence of dopamine in the brain destroyed the irregular body movements. man eats the food that causes the formation of the neurotransmitters. tthree neurotransmitters: dopamine, serotoni...

cognitive deficits such as impairments in attention, memory, information processing and executive functioning can be found in some parkinson's disease (pd) patients. recent studies suggested that pd drivers generally performed poorer than their healthy age-matched controls with regards to their cognitive and motor abilities during the psychometric testing. according to michon’s model of ca...
