Diabetes mellitus is associated with distribution of cognitive functioning. Hyperglycemia Diabetes mellitus is associated with distribution of cognitive functioning. Hyperglycemia induced oxidative stress has been proposed as a cause of memory complications of diabetes including cognitive impairment. The aim of this study was to examine total green tea extract (TGTE), a potent free radical scav...

Introduction: Sleep disorders are common problems in modern societies affecting different aspects of individuals' lives. Many studies have reported that sleep deprivation (SD) leads to impairments in hippocampus-dependent learning and memory formations. Physical exercise has been shown to improve learning and memory. The objective of the current study was to investigate the effects of Voluntary...

cognitive deficits have been observed in patients with multiple sclerosis (ms) because of hippocampal insults. oxidative stress plays a key role in the pathophysiology of ms. the aim of this study was to evaluate the effects of crocus sativus l., commonly known as saffron, on learning and memory loss and the induction of oxidative stress in the hippocampus of toxic models of ms. one week after ...

previous studies had reported that extracellular levels of ascorbic acid have modulatory effects on dopamine receptors. both ascorbic acid and dopamine receptor have an important role in learning and memory processes. however, the central interaction between ascorbic acid and dopamine d2 receptor on spatial learning and memory has not yet been elucidated. all experiments were carried out on mal...

since anethum graveolens (dill) has phytoestrogenic compounds and it is proven that estrogens exert beneficial effects on cognition; the aim of this study was to understand if this plant can improve memory performance. male balb/c mice weighing 25-30 g were used in this study and memory was assessed by the novel object recognition task. in this method, the difference in the exploration time bet...

objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
