Gallic acid improves recognition memory and decreases oxidative-inflammatory damage in the rat hippocampus with metabolic syndrome.

Metabolic syndrome (MS) results from excessive consumption of high-calorie foods and sedentary lifestyles. Clinically, insulin resistance, abdominal obesity, hyperglycemia, dyslipidemia, and hypertension are observed. MS has been considered a risk factor in the development of dementia.

The neuropeptide-12 improves recognition memory and neuronal plasticity of the limbic system in old rats.

Aging is a stage of life where cognitive and motor functions are impaired. This is because oxidative and inflammatory processes exacerbate neurodegeneration, which affects dendritic morphology and neuronal communication of limbic regions with memory loss. Recently, the use of trophic substances has been proposed to prevent neuronal deterioration.
