Ian Sample talks to Dr Laura Pritschet, a postdoctoral fellow of psychiatry at the University of Pennsylvania, about her research using precision scans to capture the profound changes that sweep across the brain during pregnancy. She explains what this new work reveals about how the brain is reorganised in this period, whether it could it help us better understand conditions like pre-eclampsia and postnatal depression, and why women’s brains have often been overlooked by neuroscience

The science of epigenetics suggests we can pass on trauma – but trust and compassion too

Since the sequencing of the human genome in 2003, genetics has become one of the key frameworks for how we all think about ourselves. From fretting about our health to debating how schools can accommodate non-neurotypical pupils, we reach for the idea that genes deliver answers to intimate questions about people’s outcomes and identities.

Recent research backs this up, showing that complex traits such as temperament, longevity, resilience to mental ill-health and even ideological leanings are all, to some extent, “hardwired”. Environment matters too for these qualities, of course. Our education and life experiences interact with genetic factors to create a fantastically complex matrix of influence.

Researchers say transcranial direct-current stimulation can reduce ‘love trauma syndrome’

Breaking up, as the Neil Sedaka hit goes, is hard to do. The emotional pain of a romantic split can be so severe it has its own clinical name – love trauma syndrome, or LTS.

But help could be at hand for those seeking to mend a broken heart. Research shows wearing a £400 headset for just a few minutes a day may ease the misery, negativity and depression that can accompany a failed relationship.

New research into the dying brain suggests the line between life and death may be less distinct than previously thought

Patient One was 24 years old and pregnant with her third child when she was taken off life support. It was 2014. A couple of years earlier, she had been diagnosed with a disorder that caused an irregular heartbeat, and during her two previous pregnancies she had suffered seizures and faintings. Four weeks into her third pregnancy, she collapsed on the floor of her home. Her mother, who was with her, called 911. By the time an ambulance arrived, Patient One had been unconscious for more than 10 minutes. Paramedics found that her heart had stopped.

After being driven to a hospital where she couldn’t be treated, Patient One was taken to the emergency department at the University of Michigan. There, medical staff had to shock her chest three times with a defibrillator before they could restart her heart. She was placed on an external ventilator and pacemaker, and transferred to the neurointensive care unit, where doctors monitored her brain activity. She was unresponsive to external stimuli, and had a massive swelling in her brain. After she lay in a deep coma for three days, her family decided it was best to take her off life support. It was at that point – after her oxygen was turned off and nurses pulled the breathing tube from her throat – that Patient One became one of the most intriguing scientific subjects in recent history.

Elite athletes and professional gamers may have higher than average visual temporal resolution, scientists say

If you have wondered why your partner always beats you at tennis or one child always crushes the other at Fortnite, it seems there is more to it than pure physical ability.

Some people are effectively able to see more “images per second” than others, research suggests, meaning they’re innately better at spotting or tracking fast-moving objects such as tennis balls.

App-based cognitive tests found to be proficient at detecting frontotemporal dementia in those most at risk

A smartphone app could help detect a leading cause of early-onset dementia in people who are at high risk of developing it, data suggests.

Scientists have demonstrated that cognitive tests done via a smartphone app are at least as sensitive at detecting early signs of frontotemporal dementia in people with a genetic predisposition to the condition as medical evaluations performed in clinics.

Are growing rates of anxiety, depression, ADHD, PTSD, Alzheimer’s and motor neurone disease related to rising temperatures and other extreme environmental changes?

In late October 2012, a category 3 hurricane howled into New York City with a force that would etch its name into the annals of history . Superstorm Sandy transformed the city, inflicting more than $60bn in damage, killing dozens, and forcing 6,500 patients to be evacuated from hospitals and nursing homes. Yet in the case of one cognitive neuroscientist, the storm presented, darkly, an opportunity.

Yoko Nomura had found herself at the centre of a natural experiment. Prior to the hurricane’s unexpected visit, Nomura – who teaches in the psychology department at Queens College, CUNY, as well as in the psychiatry department of the Icahn School of Medicine at Mount Sinai – had meticulously assembled a research cohort of hundreds of expectant New York mothers. Her investigation, the Stress in Pregnancy study , had aimed since 2009 to explore the potential imprint of prenatal stress on the unborn. Drawing on the evolving field of epigenetics, Nomura had sought to understand the ways in which environmental stressors could spur changes in gene expression, the likes of which were already known to influence the risk of specific childhood neurobehavioural outcomes such as autism, schizophrenia and attention deficit hyperactivity disorder (ADHD).
