Ameliorative effects of thiamin on learning behavior and memory dysfunction in a rat model of hypothyroidism: implication of oxidative stress and acetylcholinesterase.

Hypothyroidism causes learning and memory impairment. Considering the neuroprotective properties of thiamine (Vitamin B1), this study was conducted to investigate the effects of thiamine on acetylcholinesterase (AChE) activity, oxidative damage, and memory deficits in hypothyroid rats.In this study, 50 rats (21 days old) were randomly divided into 5 groups and treated with propylthiouracil (0.

Folic acid improved memory and learning function in a rat model of neuroinflammation induced by lipopolysaccharide.

Folic acid (FA) plays an important role in the maintenance of normal neurological functions such as memory and learning function. Neuroinflammation contributes to the progression of cognitive disorders and Alzheimer's disease. Thus, this study aimed to investigate the effect of FA supplementation on cognitive impairment, oxidative stress, and neuro-inflammation in lipopolysaccharide (LPS)-injured rats.
