The impact of the ketogenic diet on the health of patients with Alzheimer’s disease

Abstract

INTRODUCTION:
 Diet is an integral element of every individual's health. Its impact on the functioning of the human body has fascinated scientists for years. One of the diets that alters the mechanism of the body's functioning is the ketogenic diet. The impact of the ketogenic diet on various disorders is still under investigation. It is known to have shown numerous benefits in reducing epileptic seizures, but its impact on other neurological disorders is less known. In this literature review, the efficacy of ketogenic therapies was assessed in Alzheimer's disease.
 
 AIM OF STUDY:
 Review of the current literature (since 2018) on the effects of implementing a ketogenic diet in patients with Alzheimer's disease.
 
 MATERIALS AND METHODS:
 The review was based on data gathered from the PubMed database using the keywords: 'ketogenic diet in Alzheimer’s disease,' 'ketogenic therapies Alzheimer disease,' and 'ketogenic diet in neurological disease’.
 
 SUMMARY:
 The ketogenic diet enhances the daily functioning of Alzheimer's patients. It significantly improves their cognitive functions, and changes in brain blood flow are visible in imaging studies. The ketogenic diet also positively modulates the gut microbiome in Alzheimer's patients. It represents a promising option in combating cognitive symptoms of Alzheimer's disease.
