Intranasal Insulin side effects

Conclusion: Dexmedetomidine is effective in the prevention of postoperative delirium. This finding remains after exclusion of studies at high risk of bias. Corticosteroids, melatonin receptor agonists, parecoxib, intranasal insulin, and olanzapine have potential benefit, although evidence is of moderate to very low quality. Evidence synthesis in this area is complicated by inadequate trial registration practices and incomplete adoption of core outcome sets.

Conclusion: Intranasal insulin improved story recall performance of apoe4 (-) patients with AD or MCI. Other cognitive functions were not affected, but there were some positive results in functional status and daily activity. Since IN insulin is a safe intervention, future studies should be conducted with larger doses and after proper selection of patients and insulin types.
