With many advances in treatments for Parkinson’s disease, there still exist some hurdles that have resulted in treatment failure; the reasons for failure of treatment were described, with hope separated from hype.

‘Parkinson's disease is a neurodegenerative disorder characterized by motor and nonmotor deficits majorly caused by the loss of dopaminergic cells in the Substantia Nigra pars compacta (SNc) as well as the destruction of nigrostriatal pathway. ’

The review covers various gene therapy strategies including Adeno-Associated Virus-Glutamic Acid Decarboxylase (AAV-GAD), AAV-Aromatic L-Amino Acid Decarboxylase (AAV-AADC), Lenti-AADC/Tyrosine Hydroxylase/Guanosine Triphosphate- Cyclohydrolase I (Lenti-AADC/TH/GTP-CH1), AAV-Neurturin (AAV-NRTN), α-Synuclein silencing, and PRKN gene delivery. The review also covers the advantages and disadvantages of these treatments along with the results of relevant trials.
