Brief Summary

Parkinson disease (PD) and multiple system atrophy (MSA) are progressive neurodegenerative disorders characterized by abnormal accumulation of α-synuclein. There is no effective treatment that can slow down the disease progression and both disorders are associated with severe cognitive decline. It was shown that intranasal insulin (INI) improves learning and memory in healthy and cognitively impaired non-diabetic adults. The proof-of-concept, randomized, placebo-controlled, cross-over pilot study ( NCT01206322) has shown that a single 40 international units dose of intranasal insulin improves visuospatial memory in diabetes and control subjects. This proposal includes randomized, double blinded, placebo-controlled trial of intranasal insulin (40 international units daily) in treatment of PD and MSA. The study will evaluate 22 patients with PD and 22 patients with MSA. Total duration of the study will be 2 years. The primary goal is to assess the efficacy of INI in treatment of cognitive abnormalities in both PD and MSA. The primary efficacy end point will be change of the cognitive scale ratings.

Outcome Measures

Primary Outcomes (1)

  • Change in Verbal Fluency FAS (F, A or S Words) Total Score

    Changes in Verbal Fluency FAS (a total number of F, A or S words) generated after 4 weeks of treatment compared to baseline, FAS total score is a sum of F,A, and S raw scores. The verbal fluency FAS test is used to assess phonemic fluency and verbal memory. Participants are asked to name words starting with letters F, A and S over one minute interval. The unit is a on scale, the normative data are adjusted for age and sex. The higher score means better verbal fluency.

    Baseline and post-treatment

Secondary Outcomes (3)

  • Modified Hoehn and Yahr Scale

    Baseline and post-treatment

  • Cognitive Impairment Using Montreal Cognitive Assessment (MoCA)

    Baseline and post-treatment

  • Beck Depression Inventory Score (BDI)

    Baseline and post-treatment

Other Outcomes (3)

  • Unified Parkinson's Disease Rating Scale Part III (UPDRS Part III)
