APOE4, THE DOOR TO INSULIN RESISTANT DYSLIPIDEMIA AND BRAIN FOG? A CASE STUDY
Notice bibliographique
Résumé
For decades Scientists have known that carriers of the apolipoprotein E4 (ApoE4) allele (homozygous/heterozygous) are at respectively higher risk for developing Alzheimeru2019s disease (AD). While previous research reveals that the ApoE4 variant impacts the clearance capacity and degradation of beta-amyloid from the brain, as compared with ApoE3 (wild type with normal risk) and ApoE2 (variant with accelerated clearance and reduced risk), little has been documented about ApoE4u2019s dual role in cholesterol transport, both peripheral and cerebral, and the effects of sluggish ApoE4 cholesterol transport on cerebral metabolic rate. An understanding of the connection between brain metabolism and brain fat/cholesterol transport may unlock new prevention strategies for treating patients with a comorbidity of Metabolic Syndrome (MetS) with cognitive impairment. Recent findings suggest that the ApoE4 carrier impedes the shuttling of lipids from neurons and circumvents the storage of fat within the glia lipid droplets. This sluggish transport of lipids to triglyceride droplets in the glia cells can lead to dangerous reactive oxygen species (ROS) and hydroxyl free radicals as lipids are prematurely oxidized. This case study evaluates the effects of a 10-week clinically prescribed ketogenic diet (KD) with a 68-year old male, heterozygous ApoE4 carrier, with a dual diagnosis of mild Alzheimeru2019s disease and Type 2 diabetes (T2DM). The patient was administering both long and short acting injectable insulin to mediate his T2DM for 15+ years. Clinical goals of the intervention included increased hypothalamic and peripheral insulin sensitivity as measured via blood ketones with the Abbott Precision Xtra Blood Ketone Meter to confirm metabolic flexibility; controlled plasma glucose as measured via Abbott Precison Xtra Blood Glucose Meter and HgA1c via venous draw; normalization of lipid panel via venous draw and improved memory with restoration of cognitive functionality measured via the MoCA (Montreal Cognitive Assessment). The MoCA is considered to be a Gold Standard assessment in the diagnosis of early Alzheimeru2019s disease. Physiological biomarkers for T2DM/MetS and cognitive functionality were assessed pre/mid/post intervention. These measures included: HOMA-IR, triglycerides/HDL ratio, HgA1c, fasting glucose, fasting insulin, complete fasting lipid panel and the PEAK mobile App for real time measurement of cognitive improvement. The results were statistically significant. The patientu2019s baseline MoCA improved from 23/30 (mild-AD) to 29/30 (normal > 26). His T2DM was reversed. Pre-intervention HgA1c was 7.8% (T2DM); post intervention HgA1c measured 5.5% (normal). Likewise, the patient achieved statistically significant improvements in the other aforementioned biomarkers of MetS. The results of this case study suggest that a clinically prescribed, ketogenic diet (KD) has strong potential to restore systemic insulin sensitivity and metabolic flexibility in diabetic, ApoE4 heterozygous carriers. Mechanisms of action point to normalization of homeostatic negative feedback loops resetting/restoring lipid synthesis/utilization and glucose (insulin)/fatty acid (glucagon) utilization/production in both body and brain resulting in increased cerebral metabolism, improved cognition and reversal of T2DM via renewed cellular insulin sensitivity.
