New research 'opens the possibility of using a precision-medicine approach combined with deep brain stimulations for the treatment of psychiatric disorders.' tweetycami explains how.

Severely depressed patient treated via a personalized neural biomarker.

biomarker by finding the pattern of brain activity associated with the onset of symptoms and used that data to personalize a DBS device to activate when the pattern is spotted. Specifically, the device gave a 1mA electrical stimulation for six seconds when it detected the neural biomarker.

“We’ve developed a precision-medicine approach that has successfully managed our patient’s treatment-resistant depression by identifying and modulating the circuit in her brain that’s uniquely associated with her symptoms,” stated Krystal in a statement.

The worldwide market for personalized medicine was USD 493 billion, with the North American region comprising 48.6 percent of revenue share in 2020 according to a report by Grand View Research. The precision medicine market is expected to grow at a compound annual growth rate (CAGR) of 6.2 percent during 2021-2028 per the same report.

A factor driving growth in precision medicine is the increasing number of companion diagnostic (CDx) devices and tests, especially in oncology, which help the clinician determine if the potential benefits of a particular drug or treatment will outweigh the risks or side effects. Another key factor is the rising trend of investigating the use of biomarker identification for the detection, diagnosing, monitoring, and treatment of diseases and conditions are driving the growth in precision medicine and pharmacogenomics.

Existing studies in deep brain stimulation has had limited success for depression treatment in the past because those devices only give constant electrical stimulation, and usually in only one part of the brain.According to the UCSF neuroscientists, their precision medicine approach to deep brain stimulation was able to provide nearly instantaneous relief from depression in the patient. By mapping the patient’s depression circuit to identify a personalized symptom-specific neural biomarker, the researchers have demonstrated a groundbreaking proof-of-concept for a new potential approach for the treatment of severe depression in the future.

New crew docks at China's first permanent space stationChinese astronauts began Saturday their six-month mission on China's first permanent space station, after successfully docking aboard their spacecraft. The new crew includes Wang Yaping, 41, who is the first Chinese woman to board the Tiangong space station, and is expected to become China’s first female spacewalker. “We’ll co-operate with each other, carefully conduct maneuvers, and try to accomplish all tasks successfully in this round of exploration of the universe,” said Wang in the video. China will win the space race as the rest look on I would not trust staying in a space station that China built that is now in space like all things that china builds its quality is so poor you will never know Take 4 example the non stick pots and pans you buy that are made in china after a few uses if you fry an egg or piece of meat the non stick paint sticks to your food when you turn and flip it
