The steroid hormone 17β‎-estradiol (E2) is neuroprotective in several neurodegenerative conditions, including cerebral ischemia, traumatic brain injury, and Alzheimer’s disease (AD). This chapter focuses on the evidence supporting a neuroprotective role of E2 in the hippocampus in cerebral ischemia and AD and reviews various mechanisms thought to underlie E2-induced neuroprotection. Specifically, the chapter discusses the mechanistic role of (a) the various estrogen receptor subtypes, (b) genomic versus nongenomic signaling, (c) regulation of the prosurvival Wnt/β‎−catenin pathway, and (d) anti-inflammatory effects of E2 in the hippocampus. Finally, we also discuss the role of a novel estrogen receptor co-activator protein, proline-, glutamic acid-, and leucine-rich protein 1 (PELP1) in mediating E2 genomic and non-genomic signaling, as well as the neuroprotective and cognitive-enhancing effects of E2 in the hippocampus.

Paroxysmal Sympathetic Hyperactivity

Abstract Introduction Most cases of paroxysmal sympathetic hyperactivity (PSH) result from traumatic brain injury (TBI). Little is known about its pathophysiology and treatment, and several neuroprotective drugs are used including beta-blockers. The aim of our study is to collate existing evidence of the role of beta-blockers in the treatment of PSH. Method We will search MEDLINE, Web of Science, EMBASE, Cochrane, and Google Scholar. The search terms used will cover the following terms: “paroxysmal sympathetic hyperactivity”, “traumatic brain injury” and “beta-blockers.”: No language or geographical restrictions will be applied. Two independent co-authors will screen the titles and abstracts of each article following predefined inclusion and exclusion criteria. If there is a conflict the two reviewers will find a consensus and if they cannot a third co-author will decide. Using a pre-designed and pre-piloted data extraction form, data from each included citation will be collected (authors identification, study type, TBI severity, type of beta-blockers used, dosage of the drug, clinical signs of PSH, Glasgow Coma Scale, Glasgow Outcome Scale, mortality, morbidity and length of stay). Simple descriptive data analyses will be performed and the results will be presented both in a narrative and tabular form. Results The effectiveness of beta-blockers in post-TBI PHS will be evaluated through clinical signs of PHS(increased heart rate, respiratory rate, temperature, blood pressure, and sweating), Glasgow Coma Scale, and Glasgow Outcome Scale. mortality, morbidity and length of stay. Conclusion At the end of this scoping review we will design a systematic review with metaanalysis if there are a reasonable number of studies otherwise we will design a randomized controlled trial.

Brain Health

There is a robust and compelling body of evidence supporting the ergogenic and therapeutic role of creatine supplementation in muscle. Beyond these well-described effects and mechanisms, there is literature to suggest that creatine may also be beneficial to brain health (e.g., cognitive processing, brain function, and recovery from trauma). This is a growing field of research, and the purpose of this short review is to provide an update on the effects of creatine supplementation on brain health in humans. There is a potential for creatine supplementation to improve cognitive processing, especially in conditions characterized by brain creatine deficits, which could be induced by acute stressors (e.g., exercise, sleep deprivation) or chronic, pathologic conditions (e.g., creatine synthesis enzyme deficiencies, mild traumatic brain injury, aging, Alzheimer’s disease, depression). Despite this, the optimal creatine protocol able to increase brain creatine levels is still to be determined. Similarly, supplementation studies concomitantly assessing brain creatine and cognitive function are needed. Collectively, data available are promising and future research in the area is warranted.
