In patients with Alzheimer’s disease (AD), amyloid-β (Aβ) plaques and tau protein tangles accumulate in the brain long before the appearance of clinical symptoms. Early intervention is critical for slowing neurodegeneration and disease progression. Therefore, reliable markers of early AD are needed. Lucey et al. analyzed sleep patterns in aging cognitively normal subjects and showed that non–rapid eye movement (NREM) sleep negatively correlated with tau pathology and Aβ deposition in several brain areas. The results show that alterations in NREM sleep may be an early indicator of AD pathology and suggest that noninvasive sleep analysis might be useful for monitoring patients at risk for developing AD.

In Alzheimer’s disease (AD), deposition of insoluble amyloid-β (Aβ) is followed by intracellular aggregation of tau in the neocortex and subsequent neuronal cell loss, synaptic loss, brain atrophy, and cognitive impairment. By the time even the earliest clinical symptoms are detectable, Aβ accumulation is close to reaching its peak and neocortical tau pathology is frequently already present. The period in which AD pathology is accumulating in the absence of cognitive symptoms represents a clinically relevant time window for therapeutic intervention. Sleep is increasingly recognized as a potential marker for AD pathology and future risk of cognitive impairment. Previous studies in animal models and humans have associated decreased non–rapid eye movement (NREM) sleep slow wave activity (SWA) with Aβ deposition. In this study, we analyzed cognitive performance, brain imaging, and cerebrospinal fluid (CSF) AD biomarkers in participants enrolled in longitudinal studies of aging.

Today in the Mail’s pullout, the twins focus on anti-ageing your brain, and show you simple strategies to give it a boost — from telling you why you’re becoming forgetful to revealing the techniques you can use to improve brain health and function.

Yes, in the ‘spouse’ seat during counselling was Xand, his identical twin and fellow telly doctor.

It’s quite a revelation that these two — both contenders for the title of TV’s sexiest doctor, surely — have a relationship that might require them even to think of counselling.

Thanks so much to Luanna Helena for having me on Creatively Speaking Radio to discuss Bioquark Inc. (http://www.bioquark.com) and nature’s clues for human regeneration, disease reversion, and age rejuvenation -

Also got to introduce our new mosquito / “ectocrinome” research program — (https://www.bizjournals.com/philadelphia/news/2019/01/02/bio…nefit.html) —

The vast global DNA library resulting from mass genomic profiling is helping us understand how we could extend “longevity”, that is living younger and healthier for longer. It also means the search for the elixir of youth may no longer be the preserve of billionaires but be accessible to billions.

As the new year begins, we approach one of the most awaited life extension events of 2019: the Undoing Aging conference.

Starting off with a success

The Undoing Aging conference series started off in 2018, with the first being held in Berlin, Germany, in mid-March. Especially when you consider that UA2018 was the inaugural event of the series, it was extremely successful; the three-day conference organized by SENS Research Foundation (SRF) and Forever Healthy Foundation (FHF) brought together many of the most illustrious experts in the fields of aging research, biotechnology, regenerative medicine, AI for drug discovery, advocacy and policy, and business and investment.

LEAF writer Nicola Bagalà considers whether living past 40 is fundamentally different from living past 80.

Imagine this scene: you, a life extension supporter, are with a group of people talking about this and that, and, at one point, the opportunity to mention life extension presents itself. You expect people to react to it with “Yay! Longer life in good health! No more aging!” but reality doesn’t quite match up to your expectations; rather, all you get is the frustration of looking at how everyone nods approvingly when somebody puts on a great philosopher’s hat and asks rhetorically: “Would it really make us happier if we could live to 150?” Boy, is that ever irritating.

Actually, it isn’t really the specific question per se that is irritating—basically, whether living much longer than the current average would bring us more happiness—but rather that nobody ever asks whether living to 80 years old, for example, would make you any happier than you would be if you lived to only 40. If the first question is legitimate, the second one should be as well, and, by induction, you could work your way down to zero and ask whether being born makes you any happier than not being born. (Arguably, it doesn’t—babies inside the womb are generally quite peaceful and blessed looking, which is more than can be said of their mood once they pop out, but few people would agree that this is a good reason to abort each and every fetus.)

Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism.

The findings could bring about a better understanding of many cancers’ metabolic needs and lead to the development of more effective therapies for squamous cell skin cancer and other forms of epithelial cancer.

The research, led by senior authors Heather Christofk and Bill Lowry, was published in the journal Nature Communications.

A drug to fight ageing may finally be on the horizon after the first trial in humans showed ‘impressive’ results.

For many years scientists have known that an accumulation of senescent cells in the body is linked to ageing symptoms such as frailty and arthritis, as well as diseases such as Alzheimer’s and Parkinson’s.

Senescent cells — also known as zombie cells — are not completely dead so are not cleared out by the body, but are too damaged to repair tissue or carry out normal functions. Unable to repair itself or clear out the waste, the body gradually deteriorates.

A new study published in Nature Metabolism finally reveals the answer to how NMN enters the cell in order to become NAD+ and that it does not need to convert into NR to do so.

In the last few years, there has been considerable interest in restoring levels of the nicotinamide adenine dinclueotide (NAD+) coenzyme to combat age-related diseases. Evidence suggests that NAD+ systemically declines with age in a variety of organisms, including rodents and humans, which contributes to the development of many age-related diseases and metabolic conditions.

What is NAD+?
