Model can naturally detect depression in conversations

Model can naturally detect depression in conversations
To diagnose depression, clinicians interview patients, asking specific questions — about, say, past mental illnesses, lifestyle, and mood — and identify the condition based on the patient’s responses. In recent years, machine learning has been championed as a useful aid for diagnostics. Machine-learning models, for instance, have been developed that can detect words and intonations of speech that may indicate depression.

Nerve stimulation can dramatically improve lives of depressed patients

Nerve stimulation can dramatically improve lives of depressed patients
People with depression who are treated with nerve stimulation experience significant improvements in quality of life, even when their depression symptoms don’t completely subside, according to results of a national study led by researchers at Washington University School of Medicine in St. Louis. The study involved nearly 600 patients with depression that could not be alleviated by four or more antidepressants, taken either separately or in combination.

Bringing mindfulness to virtual reality

Bringing mindfulness to virtual reality
So much stress! Fast-paced lifestyles could lead to the pressure of being constantly on the top of your game by staying connected and updated. As a result, you may feel fatigued, frustrated, as well as suffer from headaches, muscle tension, and irritability. In order to help you achieve a more relaxed and coherent state, Merlin Digital, an electronics and digital technology company based in Dubai, launched IntelliSense.

Breakdown of brain's visual networks linked to mental illness

Breakdown of brain's visual networks linked to mental illness
Individual regions of the brain have to team up to get things done. And like in any team, the key to working together is communication. Duke researchers used brain imaging to identify how patterns of brain connectivity -- the ability of different brain regions to talk to each other -- can affect a person’s likelihood of developing common forms of mental illness. Surprisingly, they found that brain regions that help process what we see may play a key role in mental health.

Brain scans may help diagnose psychiatric disorders

Brain scans may help diagnose psychiatric disorders
There are no laboratory tests to diagnose migraines, depression, bipolar disorder and many other ailments of the brain. Doctors typically gauge such illnesses based on self-reported symptoms and behaviour. Now, a study shows that a kind of brain scan called functional connectivity MRI (fcMRI) – which shows how brain regions interact – can reliably detect fundamental differences in how individual brains are wired.

Insights into the genetic basis of major mental illness

Insights into the genetic basis of major mental illness
Major mental illnesses such as schizophrenia, severe depression and bipolar disorder share a common genetic link. Studies of specific families with a history of these types of illnesses have revealed that affected family members share a mutation in the gene DISC1. While researchers have been able to study how DISC1 mutations alter the brain during development in animal models, it has been difficult to find the right tools to study changes in humans.

Research reveals a better way of treating depression

Research reveals a better way of treating depression
Scientists on the Florida campus of The Scripps Research Institute (TSRI) have discovered a new target for treating major depressive disorder, a disease that affects more than 16 million American adults. Their research shows that individuals with high levels of an enigmatic receptor called GPR158 may be more susceptible to depression following chronic stress.

An unwanted side effect of human brain development

An unwanted side effect of human brain development
Schizophrenia may have evolved as an 'unwanted side effect' of the development of the complex human brain, a new study has found. The study identified changed gene expression in the area of the brain that is most different between humans and animals, including our closest species, non-human primates. Published by the Nature publishing journal, Schizophrenia, the study was undertaken by a group of researchers from Swinburne, The Florey Institute of Neuroscience & Mental Health and University of Melbourne.

A possible effective treatment for autism spectrum disorder

A possible effective treatment for autism spectrum disorder
Human chromosome 16p11.2 deletion syndrome is caused by the absence of about 27 genes on chromosome 16. This deletion is characterised by intellectual disability; impaired language, communication, and socialisation skills; and autism spectrum disorder or ASD. Research from the laboratories of Mark Bear at MIT and Jacqueline Crawley at the University of California at Davis, has identified a potential therapeutic for ASD.

Brain imaging can identify individuals with suicidal thoughts

Brain imaging can identify individuals with suicidal thoughts
Researchers led by Carnegie Mellon University's Marcel Just and the University of Pittsburgh's David Brent have developed an innovative and promising approach to identify suicidal individuals by analysing the alterations in how their brains represent certain concepts, such as death, cruelty and trouble. Suicidal risk is notoriously difficult to assess and predict, and suicide is the second-leading cause of death among young adults in the United States.
