Lack of sleep can lead to Alzheimer ’s and dementia

This study is the clearest demonstration in humans that sleep disruption leads to an increased risk of Alzheimer’s disease through an amyloid beta mechanism,” said senior author Randall Bateman, MD, the Charles F. and Joanne Knight Distinguished Professor of Neurology. “The study showed that it was due to overproduction of amyloid beta during sleep deprivation.”More than 5 million Americans are living with Alzheimer ’s, a disease characterized by gradual memory loss and cognitive decline.What is the Difference Between Alzheimer ’s and DementiaThis study indicatesthat sleeping poorly increases levels of brain proteins such as amyloid beta that are linked to Alzheimer ’s disease. But it wasn ’t clear why amyloid beta levels rise in a tired brain.Eight people ages 30 to 60 with no sleep or cognitive problems.The participants were assigned randomly to one of three scenarios:having a normal night ’s sleep without any sleep aids; staying up all night; or sleeping after treatment with sodium oxybate, a prescription medication for sleep disorders. Sodium oxybate increases slow-wave sleep— the deep, dreamless phase of sleep that people need to wake up feeling refreshed.How Do Alzheimer's Patients Die?Each scenario occurred during 36 hours of monitoring, starting in the morning and continuing through the afternoon of the following day. The researchers took samples of the fluid that surrounds the brain and s...

ConclusionsHypothalamic EPO plays a role in the central regulation of muscle and metabolic physiology while its decline contributes to aging and obesity physiology in a manner which is independent of peripheral EPO.

Authors: Lionetti V, Barile L Abstract Over the last 20 years increasing number of patients with multimorbidity and polypharmacy underwent different types of elective non-cardiac and cardiac surgery. Despite surgery is safer today than in the past, rate of perioperative major adverse cardiovascular events is still attracting significant attention from both clinicians and researchers. The perioperative myocardial infarction (PMI), a permanent damage of the heart, is a major cause of short and long term morbidity and mortality in current surgical populations. Although it is primarily the result of local myocardial is...

CONCLUSIONS: Intraoperative acupuncture at HT7 and ear Shen Men did not reduce PAED scores after myringotomy tube placement. Based on these data, it is therefore unlikely that alarger study of the same design would demonstrate a significant effect of intraoperative acupuncture on emergence delirium after brief sevoflurane anesthesia. However, other acupuncture points or techniques could be considered. PMID: 31808657 [PubMed - as supplied by publisher]

CONCLUSIONS: This study did not support an association between statin use and diagnostic conversion but suggested a possible association between statin use and cognitive change in EMCI. Additional randomized clinical trials of statins may be warranted in the prodromal EMCI stage of AD. PMID: 31806426 [PubMed - as supplied by publisher]

We present the case of a 4-year-old child who was admitted owing to the complaint of recurrent pancreatitis and had not previously been diagnosed with having metabolic disease. During inpatient treatment for acute pancreatitis, convulsions occurred with concomitant hyperammonemia, metabolic acidosis, coagulopathy, and shock 1 week after the administration of total parenteral nutrition. He was diagnosed to have PA after a metabolic work-up and confirmed to have novel mutation by molecular genetic analysis. Because children with PA may have acute pancreatitis, although rare, vomiting and abdominal pain should raise a suspici...

Purpose Based on the possibility that early-phase florbetaben (E-FBB) brain PET can be a surrogate for brain perfusion imaging, we conducted this study to investigate the clinical utility of E-FBB PET instead of 18F-FDG brain PET. Materials and Methods This prospective study included 35 patients with clinical suspicion of cognitive decline or dementia and 5 healthy controls. Brain MRI, E-FBB PET, late-phase FBB PET, and FDG PET were acquired. The regional SUV ratios (SUVRs) were calculated by cortical surface region of interest analysis using individual MRI, and relationship between E-FBB and FDG PET was analyzed. All...

A prospective, case-control study was carried out, including 187 patients (93 obese, and 94 non-obese). CVD risk for each patient was evaluated according to the American College o...
