Depression News and Research

RSS

Depression is a serious medical illness that involves the brain. It's more than just a feeling of being "down in the dumps" or "blue" for a few days. If you are one of the more than 20 million people in the United States who have depression, the feelings do not go away. They persist and interfere with your everyday life.

Poor Sleep Combined With High Genetic Susceptibility Results in Greater Asthma Risk

Poor quality sleep may bolster a person's genetic susceptibility to asthma, potentially doubling their risk of being diagnosed with the condition, suggests a large UK Biobank study, published in the open access journal BMJ Open Respiratory Research.

Common Epstein-Barr virus may be a trigger for multiple sclerosis

In 1868, French physician Jean-Martin Charcot, known as the founder of modern neurology, defined a disease entity in which multiple plaques formed in the brain and spinal cord, with varying physical symptoms, called Sclérose en plaques, or in English as multiple sclerosis (MS).

T cell-driven changes in the gut may affect brain function associated with depression

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression.

Study may help identify new sex-specific treatments for depression

Depression is widely reported to be more common in women than in men, with women twice as likely to receive a diagnosis than men.

Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

Novel model tracks hippocampal synaptic plasticity to reveal molecular mechanisms

The accumulation of amyloid beta proteins, which encourage synaptic malfunction, causes cognitive decline in Alzheimer’s disease (AD), according to scientific evidence.

COVID-19 has taken a limited toll on the mental health, finds study

COVID-19 has taken a relatively limited toll on the mental health of most people around the globe, according to a paper published today in the BMJ by a McGill University-led research team involving collaborators from McMaster University, the University of Toronto, and other institutions.

Researchers find methods to awaken and revive neural stem cells

Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood. A team led by scientists from the Universities of Geneva (UNIGE) and Lausanne (UNIL) has discovered the importance of cell metabolism in this process and identified how to wake up these neural stem cells and reactivate them. Biologists succeeded in increasing the number of new neurons in the brain of adult and even elderly mice. These results, promising for the treatment of neurodegenerative diseases, are to be discovered in the journal Science Advances.

Study elucidates the cellular changes caused by exposure to adversity during childhood

A new brain connection discovered by University of California, Irvine researchers can explain how early-life stress and adversity trigger disrupted operation of the brain's reward circuit, offering a new therapeutic target for treating mental illness. Impaired function of this circuit is thought to underlie several major disorders, such as depression, substance abuse and excessive risk-taking.

Study provides new insight into the brain circuits involved in opioid addiction

The ongoing opioid epidemic continues to take a heavy toll on American communities, with more than 80,000 opioid-related deaths reported in 2021, according to the National Institutes of Health.

Pets help improve the mental health and wellbeing of older people

Furry, finned, or feathered, our family pets come in all shapes and sizes. But while these friendly faces keep us company at home, it's a very different story for people in aged care – many of whom must relinquish their beloved pet as a condition of entry.

Location is the key for psychedelic drugs to work

Location, location, location is the key for psychedelic drugs that could treat mental illness by rapidly rebuilding connections between nerve cells.

Robust new method accurately identifies eight antidepressants

In recent years, a mass spectrometry process that can detect the amounts of drugs in a biological sample, such as blood, has become a powerful diagnostic tool for helping medical professionals identify and monitor levels of therapeutic drugs in patients, which can cause unwanted or dangerous side effects.

Genetic variants that increase the risk of ADHD identified

Why are some people diagnosed with ADHD while others are not? And when is the seed of ADHD sown, in life or the womb?

Psychological trauma related to HIV could make it difficult to end the AIDS epidemic

Failing to address the psychological trauma experienced by many older people living with HIV/AIDS will make it difficult, if not impossible, to end the epidemic, according to a Rutgers study.

Microbiome therapeutic linked to quality of life improvement in patients with recurrent C. diff infection

Kevin Garey, professor of pharmacy practice and translational research at the University of Houston College of Pharmacy is reporting the first well-controlled study to demonstrate that a microbiome therapeutic, SER-109, is associated with significant quality of life improvement in patients with the debilitating recurrent infection and disease caused by Clostridium difficile (or C. diff).

Long-term deep meditation may have a beneficial effect on gut microbiota, study suggests

Regular deep meditation, practised for several years, may help to regulate the gut microbiome and potentially lower the risks of physical and mental ill health, finds a small comparative study published in the open access journal General Psychiatry.

Marine plankton samples can help understand the link between ocean pollution and chronic illnesses

Using samples from an almost century-old, ongoing survey of marine plankton, researchers at University of California San Diego School of Medicine suggest that rising levels of manmade chemicals found in parts of the world's oceans might be used to monitor the impact of human activity on ecosystem health, and may one day be used to study the connections between ocean pollution and land-based rates of childhood and adult chronic illnesses.

Fastest-evolved regions of the human genome diverged rapidly after split from chimpanzee ancestor

A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
