Parkinson's disease (PD) is affecting >10 million people worldwide for which no suitable cure has been developed so far. Roughly, about two people per thousand populations are affected with PD like symptoms especially over the age of 50. About 1% of the populations above 60 years suffer from PD-like disease. The prevalence of the disease is increasing over the years, and future projections by 2020 could be 12-14 millions people affected by the disease. Thus, exploration of suitable therapeutic measures is the need of the hour to enhance quality of the life of PD patients. PD induced brain pathology includes loss of dopaminergic neurons in the substantia niagra that could later extends to other cortical regions causing loss of voluntary motor control. Deposition of alpha-synuclein in the brain further leads to neurodegeneration. However, the exact cause of PD is still unknown. It appears that breakdown of the blood-brain barrier (BBB) and leakage of serum component into the brain could lead to neurodegeneration in PD. Thus, novel treatment strategies that are able to restore BBB breakdown and enhance neuronal plasticity and neuroregeneration in PD could be effective in future therapy. With the advancement of nanotechnology, it is worthwhile to understand the role of nanodelivery of selected agents in PD to enhance neuroprotection. In this review new role of BBB, brain edema, and neuropathology in PD is discussed. In addition, superior neuroprotection induced by nanowired delivery of a multimodal drug cerebrolysin in PD is summarized based on our own investigations.
