Brief Summary

Parkinson's disease is the second most common neurodegenerative diseases. The conventional treatment for PD has included dopaminergic treatment as Levodopa\\carbidopa or dopamine agonists, anti-cholinergics, MAOI, catechol-o-methyl transferase (COMT) inhibitors, and amantadine. Although these options have been found to be effective, they could only improve the disease symptoms, but do not modify the disease progression. Hence, researchers have focused on developing disease-modifying agents to stop or slow the progression acting as neuroprotective agents. Since the inflammation and oxidative stress play an important role in the pathophysiologic progression of PD, recent studies have investigated the mitigation of the disease pathology through anti-inflammatory and anti-oxidant agents. Cilostazol has been found to have anti-inflammatory, antioxidant, and neuroprotective effect, and has been evaluated through two animal studies to prove that it possess these effects through dampening NF-κB, and its downstream effectors including TNF-α and IL-1β, reversing the activation of glycogen synthase kinase-3 β (GSK-3β), a pivotal effector in neuronal apoptosis, contributing in preserving dopaminergic neuron integrity clarifying the enhance motor activity, activating nuclear factor erythroid-related factor 2/ heme oxygenase 1 (Nrf2/HO-1), suppressing High mobility group box 1 protein/Toll-like receptor 4 (HMGB1/TLR4) axis, and upregulatig Phosphoinositide 3-kinases/ Protein kinase B (PI3K/Akt) besides mammalian target of rapamycin (mTOR) inhibition. Hence, Cilostazol might be a potential candidate to improve the clinical outcome in PD patients.

Outcome Measures

Primary Outcomes (1)

  • Assessment of the severity of Parkinson's disease symptoms using the Movement Disorder Society-unified Parkinson's disease rating scale (MDS-UPDRS)Assessment

    MDS-UPDRS will be performed at baseline, after 12weeks and after 24 weeks. MDS-UPDRS, the revised form of UPDRS, is the most common tool used to measure progression in PD patients. It consists of 4-subscale structure: Part I, Non-Motor Aspects of Experiences of Daily Living (13 items); Part II, Motor Aspects of Experiences of Daily Living (13 items); Part III, Motor Examination (33 items); and Part IV, Motor Complications (6 items). The scores in each item vary from 0 (normal) to 4(severe).

    6 months

Secondary Outcomes (4)

  • Serum Level of BDNF Assessment:

    6 months

  • Safety Assessment

    6 months

  • Assessment of the degree of cognitive impairment with The Montreal Cognitive Assessment (MoCA)

    6 months

  • Assessment of Quality of life (QoL) USING the PDQ-39 questionnaire
