The Ketogenic Diet in the Treatment of Post-concussion Syndrome-A Feasibility Study.

ABSTRACT: Concussion is the most common form of mild traumatic brain injury (mTBI). Although most patients' symptoms resolve within a month, patients with post-concussion syndrome (PCS) may continue to experience symptoms for years and have limited treatment options. This pilot study assessed the feasibility and symptom-related effects of a ketogenic diet (KD) in patients with PCS symptoms. The Ketogenic Diet in Post-Concussion Syndrome (KD-PCS) was a single-arm trial of a 2-month KD high in non-starchy vegetables and supplemented with medium-chain triglyceride (MCT) oil. Macronutrient targets were ?70% fat, ?10% carbohydrate, and the remainder as protein as energy. We assessed feasibility by daily self-reported measure of urine acetoacetate and collection of 3-day food records and serum beta-hydroxybutyrate at multiple timepoints. We assessed symptoms by administering the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) and Modified Balance Error Scoring System (M-BESS) at baseline and month 2 and the Post-Concussion Symptom Scale (PCSS) at baseline, month 1, and month 2. Fourteen participants enrolled in the KD-PCS. Twelve participants completed the study and 11 implemented the KD (73% fat, 9% carbohydrate, and 18% protein) and achieved ketosis. One participant complained of MCT-related diarrhea that resolved and another reported nausea and fatigue that resulted in withdrawal from the study. Among compliant participants, the visual memory domain of the ImPACT improved by 12 points (p = 0.02) and PCSS scores improved by 9 points, although not statistically significant. This pilot trial suggests that the KD is a feasible experimental treatment for PCS and justifies further study of its efficacy.

Project description:Mild traumatic brain injury (TBI) persistent post-concussion syndrome (PPCS) and post-traumatic stress disorder (PTSD) are epidemic in United States Iraq and Afghanistan War veterans. Treatment of the combined diagnoses is limited. The aim of this study is to assess safety, feasibility, and effectiveness of hyperbaric oxygen treatments (HBOT) for mild TBI PPCS and PTSD. Thirty military subjects aged 18-65 with PPCS with or without PTSD and from one or more blast-induced mild-moderate traumatic brain injuries that were a minimum of 1 year old and occurred after 9/11/2001 were studied. The measures included symptom lists, physical exam, neuropsychological and psychological testing on 29 subjects (1 dropout) and SPECT brain imaging pre and post HBOT. Comparison was made using SPECT imaging on 29 matched Controls. Side effects (30 subjects) experienced due to the HBOT: reversible middle ear barotrauma (n = 6), transient deterioration in symptoms (n = 7), reversible bronchospasm (n = 1), and increased anxiety (n = 2; not related to confinement); unrelated to HBOT: ureterolithiasis (n = 1), chest pain (n = 2). Significant improvement (29 subjects) was seen in neurological exam, symptoms, intelligence quotient, memory, measures of attention, dominant hand motor speed and dexterity, quality of life, general anxiety, PTSD, depression (including reduction in suicidal ideation), and reduced psychoactive medication usage. At 6-month follow-up subjects reported further symptomatic improvement. Compared to Controls the subjects' SPECT was significantly abnormal, significantly improved after 1 and 40 treatments, and became statistically indistinguishable from Controls in 75% of abnormal areas. HBOT was found to be safe and significantly effective for veterans with mild to moderate TBI PPCS with PTSD in all four outcome domains: clinical medicine, neuropsychology, psychology, and SPECT imaging. Veterans also experienced a significant reduction in suicidal ideation and reduction in psychoactive medication use.

Project description:BackgroundKetogenic diets (KDs) are safe and tolerable in people with multiple sclerosis (MS). While many patient-reported and clinical benefits are noted, the sustainability of these diets outside of a clinical trial is unknown.AimsEvaluate patient perceptions of the KD following intervention, determine the degree of adherence to KDs post-trial, and examine what factors increase the likelihood of KD continuation following the structured diet intervention trial.MethodsSixty-five subjects with relapsing MS previously enrolled into a 6-month prospective, intention-to-treat KD intervention. Following the 6-month trial, subjects were asked to return for a 3-month post-study follow-up, at which time patient reported outcomes, dietary recall, clinical outcome measures, and laboratory values were repeated. In addition, subjects completed a survey to evaluate sustained and attenuated benefits following completion of the intervention phase of the trial.ResultsFifty-two subjects (81%) returned for the 3-month post-KD intervention visit. Twenty-one percent reported continued adherence to a strict KD and an additional 37% reported adhering to a liberalized, less restrictive form of the KD. Those subjects with greater reductions in body mass index (BMI) and fatigue at 6-months on-diet were more likely to continue on KD following trial completion. Using intention-to-treat analysis, patient-reported and clinical outcomes at 3-months post-trial remained significantly improved from baseline (pre-KD), though the degree of improvement was slightly attenuated relative to outcomes at 6-months on KD. Regardless of diet type following the KD intervention, dietary patterns shifted toward greater protein and polyunsaturated fats and less carbohydrate/added sugar consumption.ConclusionsFollowing the 6-month KD intervention study, the majority of subjects elected to continue on KD, though many pursued a more liberal limit for carbohydrate restriction. Those who experienced a greater reduction in BMI or fatigue were more likely to continue with strict KD. The 6-month KD intervention induced persistent changes to dietary habits in the months following study completion.Trial registration informationRegistered on Clinicaltrials.gov under registration number NCT03718247, posted on Oct 24, 2018.
