objective: to investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic parkinson’s disease (pd). materials and methods: in this cross-sectional study, 55 patients with idiopathic pd by mean age of 59.85 ± 11.89 years, and mean hoehn and yahr stage ...

Although physiological function of alpha-synuclein is not yet clearly understood, accumulating evidence strongly suggests it plays a crucial role in the pathogenesis of Parkinson disease. Pathologically, alpha-synuclein is a major component of Lewy bodies, which is the pathological hallmark of Parkinson disease. Alpha-synuclein pathology is observed in the brainstem nuclei, including the dorsal...

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...

introduction: parkinson’s disease is one of the most disabling diseases which by electrode implantation and stimulation of subthalamic nucleus (stn), much progress has been made in the treatment of drug resistant patient. this new method of neurosurgery may have some neuropsychological side effects on the patients. the main aim of this study is to evaluate the effects of this kind of treatment ...

parkinson`s disease (pd) is the second most common neurodegenerative disorder after alzheimer`s disease. it is a chronic and progressive disease, and mostly afflicts elderlies. pd starts with sudden onsets and the exact cause of the disease is still unknown, however there are some early symptoms that can help us to diagnose the disease and ameliorate its effects. pd is a multi-factorial disease...

parkinson's disease is a degenerative disorder of the central nervous system. the motor symptoms of parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain the cause of this cell death is unknown. homocysteine (hcy) is a non-protein amino acid. it is a homologue of the amino acid cysteine. the elevated levels of homocysteine in pl...

whole body vibration (wbv) is a contemporary treatment modality that holds promise as an exercise training method in health–compromised individuals. a growing number of studies on individuals with parkinson disease are examining whether wbv improves balance and functional mobility. however, interpreting wbv studies is challenging since there is variability in the manner in which wbv interventio...
