Abstract
The anti-viral drug interferon-alpha (IFN-α) is widely-known to induce psychiatric and cognitive effects in patients. Previous work has shown that physical exercise can have a positive effect against brain insult. We investigated the effects of a clinically-comparable treatment regime of IFN-α on cognitive function in male Wistar rats and assessed the impact of chronic treadmill running on the deficits generated by IFN-α. We found that IFN-α induced significant impairments in performance on both spatial novelty and object novelty recognition. Chronic forced exercise did not protect against IFN-α-induced learning deficits in reactivity to spatial change, but did restore the capacity for novel object recognition in IFN-α-treated animals.
