Brief summary

This study will evaluate the effect of intranasal insulin on motor and non-motor symptoms of patients with Parkinson's disease over a 12-week period.

Detailed description

This study is a single-center, parallel and double-blind study. Patients with Parkinson's disease referred to Movement Clinic of Shohada-e-Tajrish Hospital will randomly receive intranasal placebo or insulin, every day, twice a day for 12 weeks. Motor and non-motor symptoms will be evaluated in four time points; baseline, 4, 8 and 12 weeks after treatments. Primary outcome is motor symptoms (MDS-UPDRS; part III, IV), and secondary outcomes are motor (gait balance) and non-motor (MDS-UPDRS part I, II, cognition, depression, anxiety and fatigue) symptoms. Patients, researchers (physicians, outcome assessors) and data analysts are blinded.

Design outcomes

Primary

MeasureTime frameDescription
Changes in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III, IVBase line, 4, 8 and 12 weeks after interventionMovement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III, IV assess the motor signs of Parkinson's Disease; higher score means more severity of the motor symptoms.

Secondary

MeasureTime frameDescription
Disease severityBase line, 4, 8 and 12 weeks after interventionThe modified Hoehn and Yahr Scale (HY) is used to assess severity of Parkinson's Disease. The scale ranges from 1 to 5. The lower score indicates better outcome.
Risk of FallingBase line, 4, 8 and 12 weeks after interventionTinetti Balance Assessment Tool indicates the risk of falling, higher scores is indicative of low risk for falling.
Cognitive scoreBase line, 4, 8 and 12 weeks after interventionThe Montreal Cognitive Assessment (MoCA) scores range between 0 and 30 with higher scores indicative of better cognitive performance.
Depression scoreBase line, 4, 8 and 12 weeks after interventionBeck's Depression Inventory II (BDI-II) scores range between 0 and 63; higher scores is indicative of more severe depression.
Anxiety scoreBase line, 4, 8 and 12 weeks after interventionBeck Anxiety Inventory (BAI) scores range between 0 and 63; higher scores is indicative of more anxiety.
Fatigue scoreBase line, 4, 8 and 12 weeks after interventionFatigue Severity Scale (FSS) scores range between 0 and 7; higher scores is indicative of severe fatigue.
Changes in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part I, IIBase line, 4, 8 and 12 weeks after interventionMovement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part I, II assess the non motor signs of PD; higher score means more severity of the symptoms.
