Disorder

Josh Fischman: Welcome to Science, Quickly, a Scientific American podcast series. I'm Josh Fischman, Scientific American Senior Health editor. Is it possible for one person to have several completely different personalities? I've seen movies and read books that claim that this happens, but is it real? To answer that question today, I'm joined by psychotherapist and anthropologist Rebecca Lester from Washington University in Saint Louis. She'll tell us about a patient she worked with for many years, an amazing young woman…

A study by the Mental Health Services in the Capital Region of Denmark and the National Institute on Drug Abuse (NIDA) reveals that young men with cannabis use disorder are at a heightened risk of developing schizophrenia. Analyzing health records data of over 6 million people in Denmark, the researchers found a strong association between cannabis use disorder and schizophrenia, particularly among young men aged 21-30. The study suggests that up to 30% of schizophrenia cases in this age group might have been prevented by…

Shoppers looking to “pop some tags” may be drawn to disordered thrift shop displays because they signal hidden treasure in their inventory. Secondhand retailers can decrease risk perceptions and increase perceptions of hidden treasure and purchase likelihood by demonstrating high inventory knowledge through their ability to answer customer questions and share the backstories of items, according to researchers.

Even after thousands of studies, questions still linger about one of the most common diseases unique to pregnancy: preeclampsia. This disorder leads to dangerously high blood pressure in about 5 percent of U.S. pregnancies, with significantly higher rates in Black women. And it is becoming more common. The only known cure is delivery, which creates a serious dilemma: the longer that people with preeclampsia remain pregnant, the sicker they get—but the longer a fetus gestates, the healthier it will be at birth. It is…

The idea of constructing ML algorithms from scratch, without the support of frameworks like TensorFlow or Scikit-learn, was intentional and…

Camila Mendes recently got candid on the eating disorder that she spent years battling. During a recent appearance at the Going Mental podcast, the actress explained she struggled with body image issues since childhood.

In research that could lead to a fundamental treatment of autism spectrum disorder, scientists have identified the cell-specific molecular network of the developmental disability.Scientists in South Korea have succeeded in identifying the cell-specific molecular network of autism spectrum disorder. It is expected to lay the foundation for treating autism spectrum disorder. Published in the journal Molecular Psychiatry, the research was conducted by Professor Kim Min-sik’s team of researchers at the Department of New…

Falmar (UK), December 11 Despite what we are often taught to believe, daydreaming can be immensely useful. Not only can it be a source of pleasure and a way to relieve boredom, research shows that our ability to mentally escape the present can also boost creativity, problem-solving and planning, and provide an antidote to loneliness. Daydreaming, when defined as thoughts that aren't tied to what you're currently doing, occupies a good chunk of our waking lives – an…
