Characteristic patterns of inter- and intra-hemispheric metabolic connectivity in patients with stable and progressive mild cognitive impairment and Alzheimer’s disease

Alzheimer’s disease (AD) is a neurodegenerative disease with characterization of deficits in progressive memory loss, cognitive and behaviour functions. Mild cognitive impairment (MCI) is a predromal stage of AD, displaying cognitive deficit but neither marked functional impairment nor satisfying established clinical criteria for dementia or probable AD. However, not all MCI patients may eventually progress to AD (progressive MCI, pMCI)https://doi.org/10.1016/j.nicl.2013.10.

Therefore, differential diagnosis of MCI types and earlier diagnosis of AD and prediction of disease evolution are difficult

People wearing virtual reality headsets have worse balance and increased mental exertion

New research published in PLOS One has found that virtual reality use impairs physical and cognitive performance while trying to balance.

“I became interested in this topic because virtual reality headsets have recently become widely available, with great potential to make rehabilitation more enjoyable and varied for patients,” said study author Steven M. Peterson of the University of Michigan, Ann Arbor.

“While many studies have explored upper-limb activities, I wanted to understand how immersive and mentally challenging a virtual reality headset is when the user is walking around and not seated. We decided to test the realism of virtual reality by looking for stress at high heights because just the perception of heights can affect how people walk and how cautious they are.”

FDA clears deep transcranial magnetic stimulation device to treat obsessive-compulsive disorder

Promising approach to deliver personalized and non-invasive brain stimulation in clinical settings.

BrainsWay’s Brain Stimulation Device Receives FDA Approval to Treat Obsessive-Compulsive Disorder (IEEE Spectrum):

In 2013, Jerusalem-based BrainsWay began marketing a new type of brain stimulation device that uses magnetic pulses to treat major depressive disorder.

Now, thanks to positive results in a study of 100 patients, the company has received approval from the U.S. Food and Drug Administration (FDA) to market the device for a second psychiatric condition—obsessive-compulsive disorder (OCD) …

George Church talks about reversing human aging and claims they made mice live twice as long

He says this has been done successfully with mice. They have mice live twice as long. They are testing aging reversal in dogs in 2018–2019. Human treatments could be available on a general basis by 2025.

George Church is developing better and better organs using pigs. They are working to slow or reverse the aging in the organs to be used for transplant.

He says this has been done successfully with mice. They have mice live twice as long. I mean that that humans could live 160 years if that were linear.

The longest-lived vertebrate. One of the longest-lived vertebrates is this koi fish that lived 226 years.

Scientists design new metabolic technology to open scientific data for everyone

Patients want to see their medical information. Researchers want to share their data.

Now, scientists at Scripps Research have released a new technology designed to make these measurements easier to perform and more accessible to practitioners, scientists and the general public.

“This is really about data sharing and accelerating the process of discovery,” says Gary Siuzdak, Ph.D., professor at Scripps Research and co-corresponding author of the new XCMS/METLIN open data analysis platform, published recently in Nature Methods.
