Brief summary
Evaluate the efficacy of memantine on improving the cognitive impairment in patient with epilepsy
Detailed description
Epilepsy is a complex disorder, which involves much more than seizures, encompassing a range of associated comorbid health conditions that can have significant health and quality-of-life implications. Of these comorbidities, cognitive impairment is one of the most common and distressing aspects of epilepsy. Excito-toxicity, mediated by glutamate acting on N-methyl-D-aspartate (NMDA) receptors in the hippocampus, can cause memory dysfunction in epilepsy . Memantine is a low-affinity voltage-dependent uncompetitive antagonist of the NMDA-type glutamate receptor . It also has antioxidant property and increases production of brain derived neurotropic factor (BDNF)
Interventions
Memantine is a low-affinity voltage-dependent uncompetitive antagonist of the NMDA-type glutamate receptor .Memantine hydrochloride tablet was started at the dose of 5 mg once daily orally, and the same dose was given for 3months and dose is titrated to 10 mg once daily orally for the remaining 3months. Placebo was given once daily orally for6months. Patients were instructed to take the study medication at the same time every day.
Placebo was given once daily orally for6months. Patients were instructed to take the study medication at the same time every day.
