Traumatic Brain Injury Clinical Trial
Official title:
Ketogenic Diet & Functional Recovery in Moderate to Severe Traumatic Brain Injury
Traumatic Brain Injury (TBI) represents a significant public health risk in the United States leaving many survivors with significant long term cognitive deficits and at risk for neurodegenerative diseases. Despite extensive research there are no pharmacological therapies which have demonstrated significant improvement in neurological or cognitive recovery. Changes in glucose metabolism are considered the hallmark metabolic response to TBI and ketosis has been proposed as a therapy to ameliorate metabolic dysfunction. This trial investigates the therapeutic potential of a ketogenic or modified Atkins diet on neurocognitive outcome following moderate-severe TBI.
Traumatic Brain Injury (TBI) represents a significant public health risk in the United States leaving many survivors with significant long term cognitive deficits and at risk for neurodegenerative diseases. Despite extensive research there are no pharmacological therapies which have demonstrated significant improvement in neurological or cognitive recovery. Changes in glucose metabolism are considered the hallmark metabolic response to TBI and ketosis has been proposed as a therapy to ameliorate metabolic dysfunction. Further research is necessary to address the outstanding questions regarding outcome, dose, timing, route and duration of ketogenic diet (KD) or modified Atkins diet (MAD) therapy in clinical TBI. Using a multiparametric MRI and MR spectroscopy approach in conjunction with standardized neurological and neuropsychological assessments of outcome, disability, cognition, and quality of life, this trial will investigate the therapeutic potential of KD/MAD on 12 month outcome following moderate-severe TBI patients. The purpose of this project is to: 1. Determine the effect of KD/MAD on cognitive and neurological outcome following moderate - severe TBI. To date clinical studies of ketone metabolism in TBI are severely limited and have focused primarily on ketometabolism and its effects on glucose metabolism without assessing functional or cognitive outcomes. This project directly assesses the effect of KD/MAD on measures of disability, attention, memory, processing speed, language, and executive function during ketosis and will determine whether its effects outlast the duration of the diet. 2. Identify the effects of KD/MAD on cerebral metabolism following moderate - severe TBI. While the use of ketogenic fuels is receiving greater attention, little is known about the effect of the KD/MAD on neuronal metabolism. This project will use MR spectroscopy to non-invasively measure NAA, a marker of neuronal metabolism during ketosis and outside the treatment window, which will deepen our understanding of the neuroprotective mechanisms of this therapy. ;
