Biological Psychiatry

Again, severe or prolonged physiological/psychological stress can absolutely suppress the hypothalamic pituitary gonadal access.

An example of intense stress impacting testosterone was shown in a study cited in the journal Biological Psychiatry.

Researchers followed 109 people through an extremely stressful military survival course involving captivity and interrogation.

During captivity, their cortisol levels rose significantly.

From the Biological Psychiatry family of journals, this is the Biological Psychiatry Podcast, where we discuss the latest research on psychiatric disorders and their treatments.

Thank you for joining us.

I'm your host and social media editor, Alvesha Damala.

Today, we're discussing a study conducted as a collaboration between Origin, the University of Melbourne, and Monash University that tackled this very question, studying people experiencing their very first episode of psychosis who had never taken antipsychotic medication before.

The results challenge some widely held assumptions and offer a new perspective on what's really driving brain changes and early psychosis.

Joining me is Dr. Sid Chopra from Origin and the University of Melbourne, first and corresponding author of a recent paper in biological psychiatry titled Differential Effects of Illness and Antipsychotics on Cortical Thinning in First Episode Psychosis.

Dr. Chopra, welcome to the Biological Psychiatry Podcast.

Thank you.

She earned her 2004 PhD from Arizona, completed a UCLA fellowship, and served on the UCLA Cousins Center faculty before returning to Arizona in 2012.

Her work is published in the American Journal of Psychiatry, Biological Psychiatry, and Psychological Science, and she's featured in Newsweek, The New York Times, and Washington Post.

[air whooshes] Is there a grief myth that you are personally, through your research, most tired of hearing repeated as fact?

The grief myth that I think really people struggle with is the idea that grief comes in five stages, and when you get to the end of five stages, then you're done-

It would also suggest a specific type of interaction between WIMPs and ordinary matter beyond the simplest model.

The findings have been reported on the pre-press physics website archive.org and in the journal Physical Review Letters.

For the better part of a century, people have been trying to understand dark matter.

It's important because it makes up roughly eighty-five percent of all the mass in the universe.

And time now to take a brief look at some of the other stories making news in science this week with a science report.

There's more confirmation today that people who use cannabis are more likely to develop psychosis.

The findings reported in the journal Biological Psychiatry show that psychotic symptoms are likely to appear years earlier in people already prone to psychotic episodes compared to non-users.

The authors analyzed 149 studies involving more than 71,000 people, mostly in Europe, North America, and Australia.
