Heather M Francis, Richard J Stevenson
The pathophysiology of many neurological disorders involves oxidative stress, neuroinflammation, and mitochondrial dysfunction. There is now substantial evidence that diet can decrease these forms of pathophysiology, and an emerging body of literature relatedly suggests that diet can also prevent or even remediate the cognitive deficits observed in neurological disorders that exhibit such pathology (eg, Alzheimer's disease, multiple sclerosis, age-related cognitive decline, epilepsy). The current review summarizes the emerging evidence in relation to whole diets prominent in the scientific literature-ketogenic, caloric restriction, high polyphenol, and Mediterranean diets-and provides a discussion of the possible underlying neurophysiological mechanisms...

Background and Purpose: The aim of this study is to evaluate the prevalence of hypothyroidism and the change of thyroid hormone level in the children with epilepsy on a ketogenic diet (KD). Methods: The levels of serum free thyroxine (fT4) and thyroid-stimulation hormone (TSH) were measured at the start of the KD and at 6- to 12-month intervals in children with intractable epilepsy. Hypothyroidism was defined as fT4 level < 0.8 ng/dL and TSH level > 6.0 μIU/mL...

BACKGROUND: Mitochondrial diseases, a group of multi-systemic disorders often characterized by tissue-specific phenotypes, are usually progressive and fatal disorders resulting from defects in oxidative phosphorylation. MTO1 (Mitochondrial tRNA Translation Optimization 1), an evolutionarily conserved protein expressed in high-energy demand tissues has been linked to human early-onset combined oxidative phosphorylation deficiency associated with hypertrophic cardiomyopathy, often referred to as combined oxidative phosphorylation deficiency-10 (COXPD10)...

REVIEW

Although the mechanisms underlying the anti-seizure effects of the high-fat ketogenic diet (KD) remain unclear, a long-standing question has been whether ketone bodies (i.e., beta-hydroxybutyrate [BHB], acetoacetate [ACA] and acetone), either alone or in combination, contribute mechanistically. The traditional belief has been that while ketone bodies reflect enhanced fatty acid oxidation and a general shift toward intermediary metabolism, they are not likely to be the key mediators of the KD's clinical effects, as blood levels of BHB do not correlate consistently with improved seizure control...

Ketogenic diet is being increasingly utilized in recent decades because of its success as an effective tool for short and intermediate-term weight loss. Promoting physiological ketosis from a drastically low carbohydrate diet is the fundamental basis for this diet regime. Though debated, these diets have been demonstrated to be effective, at least in the short- to medium terms, to manage excess weight, hyperlipidemia, and other cardiovascular risk factors. We reviewed the cardiovascular, metabolic, anesthetic, and postsurgical profiles in the literature and summarized technical issues of anesthesia and surgery along with long-term changes from published papers...

Monogenic and polygenic mutations are important contributors in patients suffering from epilepsy, including metabolic epilepsies which are inborn errors of metabolism with a good respond to specific dietetic treatments. Heterozygous variation in solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1) and mutations of the GLUT1/SLC2A2 gene results in the failure of glucose transport, which is related with a glucose type-1 transporter (GLUT1) deficiency syndrome (GLUT1DS). GLUT1 deficiency syndrome is a treatable disorder of glucose transport into the brain caused by a variety of mutations in the SLC2A1 gene which are the cause of different neurological disorders also with different types of epilepsy and related clinical phenotypes...

Sudden unexpected death in epilepsy (SUDEP) is a leading cause of premature mortality in patients with epilepsy, and has been linked to multiple risk factors, including gender and early age at seizure onset. Despite the lack of a targeted therapy for SUDEP, it has recently been shown that a high-fat, low carbohydrate ketogenic diet (KD) enhances longevity in the epileptic Kcna1-null (KO) mouse, a validated model of SUDEP. Here, we asked whether the KD-driven prolongation of lifespan in KO mice is dependent on sex and/or age at treatment onset...

Microglia have diverse actions, ranging from synapse pruning in development to cytotoxic effects in disease. Brain energy metabolism and substrate availability vary under normal and disease states, but how these variations influence microglial function is relatively unknown. Microglia, like most other cell types, express the full complement of gene products required for both glycolytic and oxidative metabolism. Evidence suggests that microglia increase aerobic glycolysis and decrease respiration when activated by various stimuli...

Background: Glioblastoma is the commonest form of malignant brain tumour in adults, affecting 2-3 people per 100,000 per year. Despite current treatment options including surgical resection, radiotherapy and temozolomide chemotherapy, overall survival at 2 years is approximately 27%, with a median survival of 12-14 months. The ketogenic diet (KD) is postulated to work by simulating the metabolic response to fasting by promoting the utilisation of ketones as a primary energy source, and depriving the glycolytic pathways utilised by malignant glioma cells for growth...

Pyruvate dehydrogenase complex (PDHC) deficiency is a rare metabolic disorder that affects tissues with high energy demand such as the central nervous system. The clinico-radiological phenotype of Leigh's disease is one of its common presentations. We present a 9-month-old boy with rapidly progressive infantile Leigh's disease. PDHA1 gene sequencing revealed a pathological homozygous missense mutation c.131A>G or p.H44R in exon 3 consistent with PDHC deficiency. H44R is among the five mutations (H44R, R88S, G89S, R263G, and V389fs) in E1α subunit that is thiamine-responsive...

BACKGROUND AND AIMS: Glut1 Deficiency (Glut1D) is caused by impaired glucose transport into brain. The resulting epileptic encephalopathy and movement disorders can be treated effectively by high-fat carbohydrate-restricted ketogenic diet therapies (KDT) mimicking fasting and providing ketones as an alternative cerebral fuel. Recently 6-24 months follow-ups of epileptic patients reported elevated blood lipids and intima thickening of the carotid artery raising concerns about potential cardiovascular risks by KDT...

OBJECTIVE: Chronic sleep deficiency is associated with early mortality. In the epileptic population, there is a higher prevalence of sleep disorders, and individuals with severe refractory epilepsy are at greater risk of premature mortality than the general population. Sudden unexpected death in epilepsy affects 1:1000 cases of epilepsy each year. Ketogenic diet (KD) treatment is one of the few effective options for refractory seizures. Despite KD reducing seizures and increasing longevity in Kv1...

BACKGROUND: Coconut oil has been widely used to improve health because there is much information available by word of mouth, in books, and on the internet. However, researchers still continue to search for the best diets to improve the quality of life, especially for people with cognitive decline. OBJECTIVES: The aim of this review is to develop a novel dietary approach, the Keto-Mediet, which may help prevent the onset of Alzheimer's disease. METHODS: Evidence gained through literature review from 1982 to 2015 on gene-by-diet interaction and lipid and glucose metabolism in the brains of Alzheimer's patients is converted into the new Keto-Mediet approach...

The ketogenic diet's (KD) anticonvulsant effects have been well-documented for nearly a century, including in randomized controlled trials. Some patients become seizure-free and some remain so after diet cessation. Many recent studies have explored its expanded therapeutic potential in diverse neurological disorders, yet no mechanism(s) of action have been established. The diet's high fat, low carbohydrate composition reduces glucose utilization and promotes the production of ketone bodies. Ketone bodies are a more efficient energy source than glucose and improve mitochondrial function and biogenesis...
