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...

statement of problem: periodontal disease (pd) has been linked to adverse cardiovascular events by unknown mechanisms. c-reactive protein (crp) is a prognostic marker for cardiovascular disease, with reported elevated serum levels during pd. purpose: the aim of the present study was to evaluate the association between pd and higher crp levels in the serum of acute myocardial infarction (ami) pa...

One of the characteristic symptoms of patients with Parkinson Disease (PD) is a rigidity of movement. These symptoms disappear after administration of Levodopa. However, the long-term use of levodopa causes involuntary movements (dyskinesia). A proper diagnosis requires an automatic, unsupervised method for the detection and classification of levodopa induced dyskinesia. The main problem, howev...

There is increasing evidence that accumulation of redox-active iron in mitochondria leads to oxidative damage and contributes to various neurodegenerative diseases, such as Friedreich's ataxia and Parkinsons disease. In this work, we examined the existence of regulatory mechanisms for mitochondrial iron uptake and storage. To that end, we used rhodamine B-[(1,10-phenanthrolin-5-yl)amino carbony...

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...

Introduction: Parkinson disease (PD) is the second frequent human neurodegenerative disease following Alzheimer. This illness is caused by degeneration of dopaminergic neurons in the compact part of substantia nigra (SNpc). Clinical demonstrations are observable when 70% of dopaminergic neurons in SNpc and 80% of dopaminergic terminals in striatum have been degenerated. Characterization of non-...

Objectives: In the early stages, most Parkinson’s patients display some degrees of voice and speech disorders. Speech disorders can negatively affect social interactions and human life, thus treatment plans for the disorders in the early stages might be further beneficial than the late stages. Therefore, we aimed to investigate on the effect of an intervention on Persian patients with early mil...
