Assessment of neuropathological findings and medical treatment of Parkinson disease: A review of literature

Background : Parkinson disease is a long-lasting and progressive motor disorder which is identified by three critical motor symptoms which are bradykinesia, rigidity and tremor. Aim of the study: To assess the histopathological changes in the brain of Parkinson disease’s patients and the regimes used for treatment. Conclusion: Several histopathological changes in the neurons in brain of patients with Parkinson disease are α-synucleinopathies, lewy bodies, damage of synaptic neurons, and hyperactivation of microglial cell. Many regimes were used in the treatment of Parkinson disease particularly to alleviate motor symptoms. The golden goal is they should focus on preserving the synaptic neurons before they get damaged.
