  • Can Neural Network Instability in Schizophrenia be Improved With a Very Low Carbohydrate Ketogenic Diet?

    open to eligible people ages 18-65

    Wide ranging cognitive deficits are major drivers of functional decline and poor outcomes in people with schizophrenia (SZ) and bipolar disorder (BD). Medications do not target pathophysiological mechanisms thought to underlie these deficits. In the search for interventions targeting underlying cognitive impairment in SZ and BD, we look comprehensively beyond just the brain and to the potential role of dysfunctional systemic metabolism. Disrupted insulin and glucose metabolism are seen in medication-naïve first-episode SZ, suggesting that SZ itself, and not just the medications used to treat it, is associated with risk of Type 2 diabetes, cardiovascular morbidity and mortality, and more generally, accelerated aging. Even young people with SZ have increased risk of metabolic disease and cognitive deficits. Sadly, their life span is shortened by 15-20 years. BD is associated with similar but less severe disruptions in glucose and insulin metabolism and life expectancy. Although the human brain is 2% of the body's volume, it consumes over 20% of its energy, and accordingly, the brain is particularly vulnerable to the dysregulation of glucose metabolism seen in SZ and BD. While glucose is considered to be the brain's default fuel, ketones provide 27% more free energy and are a major source of energy for the brain. Ketones prevent or improve various age-associated diseases, and a ketogenic diet (70% fat, 20% protein, 10% carbohydrates) has been posited as an anti-aging and dementia antidote. The premise of the work is based on recent evidence that ketogenic diets improve dynamic neural network instability, related to cognitive deficits, aging, and Type 2 diabetes (Mujica-Parodi et al., Proc Natl Acad Sci U S A. 2020;117(11):6170-7.). The rigor of the work rests on findings of (1) poor cerebral glucose homeostasis in SZ and BD, (2) neural network instability in SZ and BD, and (3) direct effects of ketosis on network instability. Unknown is whether ketogenic diets can improve network instability in people with SZ and BD.

  • Therapeutic Ketogenic Diet in Anorexia Nervosa

    open to eligible people ages 18-45

    This study will investigate the effects of therapeutic ketogenic diet (TKD) on eating behavior including drive to restrict, body dissatisfaction, mood and anxiety in individuals with anorexia nervosa who have been weight normalized (body mass index of 17.5 or greater) but continue to struggle with eating disorder behaviors including a high drive for thinness and body dissatisfaction.

  • Ketogenic Diet vs Standard Anti-cancer Diet Guidance for Patients With Glioblastoma in Combination With Standard-of-care Treatment

    Sorry, not currently recruiting here

    This is a Phase 2, randomized two-armed, multi-site study of 170 patients with newly diagnosed glioblastoma multiforme. Patients will be randomized 1:1 to receive Keto Diet, or Standard Anti-Cancer Diet. All patients will receive standard of care treatment for their glioblastoma. The Keto Diet intervention will be for an 18-week period and conducted by trained research dietitians. Daily ketone and glucose levels will be recorded to monitor Keto Diet adherence. This two-armed randomized multi-site study aims to provide evidence to support the hypothesis that a Keto Diet vs. Standard Anti-Cancer Diet improves overall survival in newly diagnosed glioblastoma multiforme patients who receive standard of care treatment.

  • Ketogenic Diet for Pediatric Acute Brain Injury

    Sorry, currently not accepting new patients, but might later

    This is a prospective pilot study evaluating the safety and feasibility of implementing the ketogenic diet in children admitted to the pediatric intensive care unit with acute brain injury such as stroke, traumatic brain injury, and intracerebral hemorrhage. Animal studies suggest that in the aftermath of injury the brain's ability to use glucose as a fuel is impaired. The ketogenic diet is a high fat, low carbohydrate diet which is already used in clinical practice for the treatment of medication resistant epilepsy and is intended to switch the body over to burning fat rather than carbohydrates for fuel. In lieu of their standard tube-feeds, 5-10 children admitted to the PICU with these diagnoses will receive low carbohydrate, high fat ketogenic feeds for 2 weeks. We hypothesize that ketones will be detectable through serum tests and MRI spectroscopy studies of the brain within several days of diet initiation, and that there will be a low incidence of side effects and adverse events, Measures of interest will include the incidence of kidney stones, excessive acidosis and excessive hypoglycemia. The feasibility of implementing this protocol for a larger efficacy trial will be assessed through serial measurements of blood glucose, beta-hydroxybutyrate (a type of ketone body), and serum bicarbonate levels. In addition, levels of ketone bodies within the brain will be measured through MRI spectroscopy sequence which will be acquired at the same time as a follow-up MRI brain study ordered for clinical purposes.
