Fight Aging! Newsletter, March 18th 2019
This study provides a possible reason why genes carrying health risks have persisted in human populations. The second found evidence for multiple variants in genes related to ageing that exhibited antagonistic pleiotropic effects. They found higher risk allele frequencies with large effect sizes for late-onset diseases (relative to early-onset diseases) and an excess of variants with antagonistic effects expressed through early and late life diseases.
There also exists other recent tangible evidence of antagonistic pleiotropy in specific human genes. The SPATA31 gene has been found under strong positive genomic sele...

Fewer Calories, Better Cell Performance
Calorie restriction, reducing calorie intake by 40% or so while maintaining optimal micronutrient intake, is the most reliable way to upregulate all of the cellular maintenance processes that act to improve cell and tissue function. This response to famine evolved very early on in the history of life on our planet, and near all organisms assessed by the research community have a cellular metabolism that operates more efficiently when calories intake is restricted. While everyone should consider trying calorie restriction, given the health benefits it conveys, and given that it costs nothing, it isn't the path to a sizable ...

Medtronic Introducing Deep Brain Stimulation for Epilepsy Control in U.S.
Medtronic is introducing in the United States its deep brain stimulation therapy (DBS) as an option for treating drug-resistant epilepsy.
About a third of epilepsy patients don’t respond positively to existing drug regimens, leaving patients with little recourse against the disease. DBS therapy involves delivering small pulses of electric current to the anterior nucleus of the thalamus. This part of the brain is usually part of a network through which seizures propagate, and stimulating it has shown to help disrupt seizures.
The therapy is indicated for adult patients who have tried three different drugs already a...

Depth Electrodes or Digital Biomarkers? The future of mood monitoring
Stereoelectroencephalography (SEEG) vs.Mindstrong HealthMood Monitoring via Invasive Brain Recordings or Smartphone SwipesWhich Would You Choose?That ' s not really a fair question. The ultimate goal of invasive recordings is one of direct intervention, by delivering targeted brain stimulation as a treatment. But first you have to establish a firm relationship between neural activity and mood. Well, um, smartphone swipes (the way you interact with your phone) aim to establish a firm relationship between your “digital phenotype” and your mood. And then refer you to an app for a precision intervention. Or to your therapi...

CBD Oil for Depression, Schizophrenia, ADHD, PTSD, Anxiety, Bipolar & More
In conclusion, the studies presented in the current review demonstrate that CBD has the potential to limit delta-9-THC-induced cognitive impairment and improve cognitive function in various pathological conditions.
Human studies suggest that CBD may have a protective role in delta-9-THC-induced cognitive impairments; however, there is limited human evidence for CBD treatment effects in pathological states (e.g. schizophrenia).
In short, they found that CBD may help alleviate the negative impact of a person with schizophrenia from taking cannabis, both in the psychotic and cognitive symptoms associated with schizophrenia. T...

CBD Oil — What are Potential Effects on the Brain?
According to this study, CBD causes hormonal changes that can lessen the intensity of anxiety disorders including generalized anxiety disorder, PTSD, and social anxiety.
Regulates Behaviour & Cognition
CBD interacts with a broad range of receptors, and through complicated processes, it works as a therapeutic agent. While behavioral patterns tend to be complicated for many people, there are ways that CBD can reduce destructive behavior and facilitate positive change. For instance, addiction is one of the areas that lead to unproductive behavioral patterns, and CBD has been used successfully to treat different forms of a...

Scientists Translate Brain Signals Into Speech
Our brain signals are a window into our souls. More broadly, brain-computer interfaces that read those signals and accompanying algorithms that process the signals are the windows. Researchers at Columbia University have been working on trying to understand what our brains are thinking about, and in particular interpreting the signals produced by the auditory cortex into coherent speech.
The researchers have been using intracranial encephalography (iEEG), also known as electrocorticography (ECoG), which involves placing an implant directly onto the surface of the brain, to read the signals. Special algorithms, based on de...

New Research Raises Concerns About the Dangers of Marijuana Use
Whatever your personal position on the subject of marijuana legalization, whether for medical or recreational use, a growing body of research reveals concerns over the potential harms caused by cannabis.
The concerns are more than academic. With increasing public support (varying by demographic cohorts) for legalized marijuana, and 10 states legalizing recreational marijuana and 33 states where medical marijuana use is legal, the cannabis movement is just gaining steam.
A new Pew Research Center report shows that 6 in 10 Americans (62 percent) say marijuana should be legal. Millennials support legalized marijuana more tha...

Medgadget ’s Best Medical Technologies of 2018
The year 2018 is nearly over, and it is time for us to reveal what we believe were the most notable developments in medical technology. We considered a technology’s clinical importance, the greatness of the leap that it’s making over existing solutions, as well as how we expect it to be adopted by doctors and nurses. Additionally, we place great value on the novelty, the engineering brilliance embedded within, and how a new technology makes possible what recently seemed nearly inconceivable. As such, a technology that may not be the most useful, but if it strikes our imagination and opens up new possibilities i...

Researchers say they ’ve identified two brain networks – one responsible for volition, the other for agency – that together underlie our sense of free will
By Emma Young
While there’s still a debate about whether we have free will or not, most researchers at least agree that we feel as if we do. That perception is often considered to have two elements: a sense of having decided to act – called “volition”; and feeling that that decision was our own – having “agency”.
Now in a paper in PNAS, Ryan Darby at Vanderbilt University Medical Center and colleagues have used a new technique – lesion network mapping – to identify for the first time the brain networks that underlie our feelings of volition and for agency. “Together, these networks may underlie ou...
