Hyperbaric Oxygen Therapy (HBOT) Research for Dementia.
Abstract Vascular dysfunction is entwined with aging and in the pathogenesis of Alzheimer's disease (AD) and contributes to reduced cerebral blood flow (CBF) and consequently, hypoxia. Hyperbaric oxygen therapy (HBOT) is in clinical use for a wide range of medical...
Abstract Background: Neurofeedback (NF) training, as a method of self-regulation of brain activity, may be beneficial in elderly patients with mild cognitive impairment (MCI). In this pilot study, we investigated whether a sensorimotor (SMR)/theta NF training could...
Abstract One of the well-documented behavioral changes that occur with advancing age is a decline in executive functioning, for example, attentional control. Age-related executive deficits are said to be associated with a deterioration of the frontal lobes....
Abstract Background: Mild cognitive impairment (MCI) is a symptom characterizing cognitive decline and a transitional state between normal aging and dementia; however, there is no definitive diagnosis and treatment for MCI. Neurofeedback (NF), which is a training...
Abstract Recent studies have shown that hyperbaric oxygen (HBO) has a therapeutic effect on vascular dementia (VD); however, the exact mechanism remains unclear. This article aims to reveal the protective effects and underlying mechanisms of HBO on VD. A total of 158...
Abstract Background: Vascular dementia (VD) is a common type of disease in the elderly. Numerous clinical trials have suggested that hyperbaric oxygen is an effective and safe complementary therapy for aging-related disorders. However, there is no reliable systematic...
Abstract Mild cognitive impairment (MCI) is a syndrome characterized by a decrease in cognitive abilities, while daily function is maintained. This condition, which is associated with an increased risk for the development of Alzheimer's disease, has no known...
Abstract: Hypoxia causes a cascade of activity from the level of the individual down to the regulation and function of the cell nucleus. Prolonged periods of low oxygen tension are a core feature of several disease states. Advances in the study of molecular biology...
There is a real need for new interventions for Alzheimer’s disease (AD). Hyperbaric oxygen therapy (HBOT), the medical administration of 100% oxygen at conditions greater than 1 atmosphere absolute, has been used successfully to treat several neurological conditions, but its effects on AD pathology have never been thoroughly examined. Therefore, we exposed old triple-transgenic (3xTg) and non-transgenic mice to HBOT followed by behavioral, histological, and biochemical analyses. HBOT attenuated neuroinflammatory processes by reducing astrogliosis, microgliosis, and the secretion of proinflammatory cytokines (IL-1β and TNFα) and increasing expression of scavenger receptor A, arginase1, and antiinflammatory cytokines (IL-4 and IL-10). Moreover, HBOT reduced hypoxia, amyloid burden, and tau phosphorylation in 3xTg mice and ameliorated their behavioral deficits. Therefore, we suggest that HBOT has multifaceted effects that reduce AD pathologies, even in old mice. Given that HBOT is used in the clinic to treat various indications, including neurological conditions, these results suggest HBOT as a novel therapeutic intervention for AD.
