Mysterious Viral DNA in Human Genome Linked With Psychiatric Disorders

Around 8% of human DNA is made up of genetic sequences acquired from ancient viruses.

Around 8% of human DNA is made up of genetic sequences acquired from ancient viruses. These sequences, known as human endogenous retroviruses (or Hervs), date back hundreds of thousands to millions of years – with some even predating the emergence of Homo sapiens. Our latest research suggests that some ancient viral DNA sequences in the human genome play a role in susceptibility to psychiatric disorders such as schizophrenia, bipolar disorder and major depressive disorder. Hervs represent the remnants of these infections with ancient retroviruses. Retroviruses are viruses that insert a copy of their genetic material into the DNA of the cells they infect.

The Crucial Decision That Can Protect Women’s Health as They Age — The Wall Street Journal

Removing ovaries with a hysterectomy might increase risk of heart disease, stroke and dementia

A 2013 study in the journal Obstetrics and Gynecology found that among more than 750,000 women, about 46% removed their ovaries at the time of hysterectomy whereas 54% didn’t. Even premenopausal women who preserve their ovaries during a hysterectomy are at increased risk of dementia and heart disease but less so, according to multiple studies.

The health risks associated with the removal of ovaries are significant.

Rocca was co-author of a 2021 Jama Network Open study that found that women under 46 who removed both of their ovaries with or without a hysterectomy had an increased risk of mild cognitive impairment and performed worse on cognitive tests 30 years later compared with women who didn’t undergo the procedure.

Another study Rocca co-wrote found that women who had ovaries removed before age 50 faced higher risks for several conditions years later, including heart disease and osteoporosis.

Other studies have linked the procedures to an increased risk of dementia, Parkinson’s disease and accelerated aging.

For The First Time, Scientists Show Structural, Brain-Wide Changes During Menstruation

The constant ebb and flow of hormones that guide the menstrual cycle don't just affect reproductive anatomy.

The constant ebb and flow of hormones that guide the menstrual cycle don't just affect reproductive anatomy. They also reshape the brain, and a new study has given us insight into how this happens. Led by neuroscientists Elizabeth Rizor and Viktoriya Babenko of the University of California Santa Barbara, a team of researchers tracked 30 women who menstruate over their cycles, documenting in detail the structural changes that take place in the brain as hormonal profiles fluctuate. The results, which are yet to be peer-reviewed but can be found on preprint server bioRxiv, suggest that structural changes in the brain during menstruation may not be limited to those regions associated with the menstrual cycle. "These results are the first to report simultaneous brain-wide changes in human white matter microstructure and cortical thickness coinciding with menstrual cycle-driven hormone rhythms," the researchers write.
