Parameters of Oxidative Stress and Behavior in Animals Treated with Dexametasone and Submitted to Pentylenetetrazol Kindling

Aerobic exercise, alone or combined with an anti-inflammatory drug, reduces the severity of epileptic seizures and levels of central pro-inflammatory cytokines in an animal model of epileptic seizures

Epilepsy is a chronic neurological disorder and there is increasing evidence about the role of inflammation in epileptogenesis. These findings have spurred the search for new immunomodulatory approaches that can improve prognosis. Using an animal model of chemically-induced epileptic seizures, we tested exercise alone as non-pharmacological therapy, and exercise combined with an anti-inflammatory drug. Five groups were used: sedentary, diazepam, aerobic exercise alone, aerobic exercise combined with an anti-inflammatory drug, and naive control. Our goal was to compare the severity of the epileptic seizures between groups as well as seizure latency in a pentylenetetrazole-induced paradigm. Cytokine levels (IL-1β, TNF-α, and IL-10) were measured. Both exercise groups showed a reduction in seizure severity and lower levels of pro-inflammatory cytokines in the cortex, while the levels of cytokines in the hippocampus remained unaffected.
