Deficits in memory function have been observed in pentylentetrazole (PTZ)-kindled rats. In the present study we examined the effects of atorvastatin ((3-hydroxy-3-methylglutaryl-coenzyme A [HMG-CoA] reductase inhibitor) on PTZ kindling and related memory deficits in rats trained with the passive avoidance test. Subconvulsive PTZ doses rendered a gradual increase in seizure activity. PTZ kindling caused long-term memory to deteriorate. Atorvastatin per se and in PTZ-kindled rats improved learning and memory functions. It also prolonged latency (time to appearance of spike potentials) and diminished the amplitude and frequency of spike potentials, which indicate epileptic discharges. These novel findings suggest that the favorable effect of the atorvastatin on memory deficits provoked by PTZ kindling might be of clinical utility.
Research Highlights
► Pentylenetetrazol kindling deteriorated long-term memory.
► Atorvastatin decreased seizure susceptibility in pentylenetetrazol-induced kindling.
► Atorvastatin improved long term memory deficit in pentylentetrazol-kindled rats.
► Statins should be further studied as a potential approach to preventing the development of epilepsy and associated memory deficits.
