Neurological Disorders are diseases of the central and peripheral nervous system. The disorders Parkinson__ampersandsignrsquo;s disease and myopathy are the traumatic disorders of the nervous system. The myopathies are neuromuscular disorders in which the primary symptom is muscle weakness due to dysfunction of muscle fiber and Parkinson__ampersandsignrsquo;s disease (PD) belongs to a group of conditions called motor system disorders, which are the result of the loss of dopamine-producing brain cells. Biological network is a network that applies to the biological system. These networks are widely used in many branches of biology as convenient representation of patterns of interaction between appropriate biological elements.Proteins-protein interaction (PPIs) in a cell form protein interaction networks (PINs) where proteins are nodes and their interaction are edges. In the present work we will investigate the network properties of proteins in disease protein-protein interaction network framework and identify common proteins between myopathy and Parkinson diseases.
