ABSTRACT
This chapter discusses the principles and impacts of ketogenic diets and medium-chain fatty acids on cognitive function. The completers achieved ketosis and their cognitive function was significantly improved compared to baseline despite reverting to baseline after the washout period. The subjects showed significant improvements on the immediate and delayed logical memory test and digit-symbol coding test compared to baseline. However, the effects of coconut oil supplementation on cognitive function in patients with AD have also been examined. Some clinical trials have demonstrated that classic and MCT ketogenic diets improve cognitive functions in patients with mild AD. The impacts of ketogenic diets on the cognitive function of patients with AD should also be analyzed by well-designed studies using large cohorts. Cognition is the mental act of acquiring knowledge and understanding through thoughts, experiences, and sensations. In other words, cognitive function includes thinking, reasoning, and remembering.
