Epilepsy as well as chronic use of most antiepileptic drugs predisposes to cognitive impairment. Curcumin has been reported to possess antioxidant, anticonvulsant as well as neuroprotective potential. Hence, this study was conducted to evaluate the effect of curcumin against seizures, cognitive impairment and oxidative stress in pentylenetetrazole-induced kindling in rats. MAIN
The effect of pretreatment with curcumin (100, 200 and 300mg/kg, orally) on pentylenetetrazole (PTZ)-induced kindling, kindling-induced cognitive impairment and oxidative stress was evaluated. Male Wistar rats were injected PTZ (30mg/kg, i.p.) once every alternate day (48±1h) until the development of kindling. Cognitive impairment was assessed using elevated plus maze and passive avoidance test while the oxidative stress parameters (malondialdehyde and glutathione) were estimated in the whole brain at the end of experiments. KEY
PTZ, 30mg/kg, induced kindling in rats after 31.0±1.4days. Curcumin showed dose-dependent anti-seizure effect. Curcumin (300mg/kg) significantly increased the latency to myoclonic jerks, clonic seizures as well as generalized tonic-clonic seizures, improved the seizure score and decreased the number of myoclonic jerks. PTZ kindling induced a significant oxidative stress and cognitive impairment which was reversed by pretreatment with curcumin in a dose-dependent manner.
The results indicate that pretreatment with curcumin ameliorates seizures, oxidative stress and cognitive impairment in PTZ induced kindling in rats. These results thus suggest the potential of curcumin as an adjuvant in epilepsy both to prevent seizures as well as to protect against seizure induced memory impairment.

A condition characterized genotypically by mutation of the distal end of the long arm of the X chromosome (at gene loci FRAXA or FRAXE) and phenotypically by cognitive impairment, hyperactivity, SEIZURES, language delay, and enlargement of the ears, head, and testes. MENTAL RETARDATION occurs in nearly all males and roughly 50% of females with the full mutation of FRAXA. (From Menkes, Textbook of Child Neurology, 5th ed, p226)
One of the CARBONIC ANHYDRASE INHIBITORS that is sometimes effective against absence seizures. It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition. (From Smith and Reynard, Textbook of Pharmacology, 1991, p337)
A yellow-orange dye obtained from tumeric, the powdered root of CURCUMA longa. It is used in the preparation of curcuma paper and the detection of boron. Curcumin appears to possess a spectrum of pharmacological properties, due primarily to its inhibitory effects on metabolic enzymes.
A dual inhibitor of both cyclooxygenase and lipoxygenase pathways. It exerts an anti-inflammatory effect by inhibiting the formation of prostaglandins and leukotrienes. The drug also enhances pulmonary hypoxic vasoconstriction and has a protective effect after myocardial ischemia.
A condition of low alertness or cognitive impairment, usually associated with prolonged mental activities or stress.
