Abstract: Parkinson’s disease is a progressive neurodegenerative disorder of dopaminergic striatal neurons in
basal ganglia. Treatment of Parkinson’s disease (PD) through dopamine replacement strategies may provide
improvement in early stages and this treatment response is related to dopaminergic neuronal mass which
decreases in advanced stages. This treatment failure was revealed by many studies and levodopa treatment
became ineffective or toxic in chronic stages of PD. Early diagnosis and neuroprotective agents may be a suitable
approach for the treatment of PD. The essentials required for early diagnosis are biomarkers. Characterising the
striatal neurons, understanding the status of dopaminergic pathways in different PD stages may reveal the effects
of the drugs used in the treatment. This review updates on characterisation of striatal neurons, electrophysiology
of dopaminergic pathways in PD, biomarkers of PD, approaches for success of neuroprotective agents in clinical
trials. The literature was collected from the articles in database of PubMed, MedLine and other available literature
resources.
