|A brain signal for psychosis risk
||Only one third of individuals identified as being at clinical high risk for psychosis actually convert to a psychotic disorder within a three-year follow-up period. This risk assessment is based on the presence of sub-threshold psychotic-like symptoms. Thus, clinical symptom criteria alone do not predict future psychosis risk with sufficient accuracy to justify aggressive early intervention, especially with medications such as antipsychotics that produce significant side effects.

|Is Nonviolence Effective?
||The evidence for the effectiveness of nonviolent resistance is mounting. In the past 100 years, nonviolent campaigns were nearly twice as likely to achieve full or partial success as were violent campaigns and the advantage for violent campaigns held even when controlling for the authoritarianism of the regime.read more
|Estradiol preserves key brain regions in postmenopausal women at risk for dementia
||When initiated soon after menopause, hormone therapy with estradiol prevented degeneration in key brain regions of women who were at heightened dementia risk, according to a new study. The investigators also found that another type of hormone therapy, marketed under the brand name Premarin, was far less protective. Premarin is a mixture of 30-plus substances derived from the urine of pregnant mares. Estradiol -- the dominant sex-steroid hormone in woman -- accounts for about 17 percent of Premarin's total content. Other Premarin components exert various endocrinological effects on different tissues.

|New rehabilitation methods for amputees, stroke patients developed
||When use of a dominant hand is lost by amputation or stroke, a patient is forced to compensate by using the nondominant hand exclusively for precision tasks like writing or drawing. Presently, the behavioral and neurological effects of chronic, forced use of the nondominant hand are largely understudied and unknown. Now, researchers have shed light on how a patient compensates when losing a dominant hand and suggest improved rehabilitation techniques for those suffering from amputation or stroke.
|Nicotine withdrawal weakens brain connections tied to self-control over cigarette cravings
||A new brain imaging study shows how smokers suffering from nicotine withdrawal may have more trouble shifting from a key brain network"”known as default mode, when people are in a so-called "introspective" state -"” and into a control network that could help exert more conscious, self-control over cravings and to focus on quitting for good.

|Chronic pain research delves into brain: New insight into how brain responds to pain
||New insights into how the human brain responds to chronic pain could eventually lead to improved treatments for patients, researchers say. Chronic pain is common throughout the world. More than 100 million Americans are believed to be affected by chronic pain. "People living with chronic headache and other forms of chronic pain may experience reduced quality of life, as the pain often prevents them from working, amongst other things. It is therefore imperative that we understand the causes of chronic pain, not just attempt to treat the symptoms with medication," the lead author said.

|Letters: aid workers need to blow off steam
||Emotional and physical release is crucial for people working under stress, but controlled and long-term training is much better than drinking and partying, says a psychologist to aid workersIn July 1999 I was in Kosovo on my first assignment as a mental health officer. I was invited to a party that one of the humanitarian aid agencies was giving, mainly for expatriates. We were in the middle of a Muslim neighborhood where people had suffered massacres and very strong oppression for the last 10 years. The party had very big loudspeakers playing western music, a lot of dancing, alcohol and couples getting together.I was pretty shocked. Why would we do this? Why we would we be so disrespectful, in the middle of an Islamic neighborhood, where people were trying to recover from a war?In hindsight, the party reflected the needs of these expatriates who came to Kosovo and found a horrific situation. There were mass graves being opened, and stories of immense suffering and torture. People were trying to connect with each other in a non-professional environment, to relax by drinking alcohol and letting the tension out of their bodies with dancing and movement.At the party I met an Albanian Kosovar who was interpreter for human rights work, and when I told her that I was a psychologist she broke down crying. In a corridor with people dancing and drinking around us, she cried and explained that her job was translating stories of war, torture and missing family members – things she had gone through herself in the past. As she translated she would sometimes start crying, and the expatriate she worked for would say, "well, if you can't cope with this maybe you should quit your job." But of course she couldn't, because her whole family was financially dependent on her. She wanted to help tell the world what had happened to her society, but she was in need herself.Hearing her reflecting on her feelings within the context of this party made me wonder how else aid workers could find ways of relaxing, getting the body moving and sharing, besides drinking alcohol until 5am. That's where my interest in psychosocial support for aid workers started.In the last 15 years aid agencies have recognised their staffs' need for psychosocial support, but not many are meeting it, because few have the capacity. Even those that do can often only offer short training modules of one to four hours during induction programmes or short field visits. In the field, faced with the compelling and urgent needs of others, aid workers have less capacity to tune into their own needs.There are very good mindfulness-based stress management courses than could help, but they take time – typically two-hours once a week for eight weeks. The idea is to go slowly enough to be able to actually realise what you are learning and build it into your daily life. But the daily life of aid workers is often not very stable, and always very time constrained. When they're not in the field, they're resting at home for just one month between deployments. Few can take two months off for mindfulness training.That's why the Garrison Institute in upstate New York created the contemplative-based resilience training. Incorporating secular meditation, yoga and movement, and psychosocial education, the material is specifically adapted for aid workers and covered in a four-day residential training that fits their schedules. Online forums keep participants connected to each other after the initial training, and they can access einforcing video, audio and documentary resources via an app on their phones.Researchers will be formally studying CBRT's effectiveness, but the anecdotal evidence so far – including my own experience teaching it and observing of what works for aid workers in the field – is that this kind of training could meet aid workers' needs for connection, movement and physical and emotional release. That could be a great boon to individual workers, their organisations and the millions who benefit from their work.Carla Uriarte is a clinical and social psychologist at the Garrison InstituteViews and reviews is a weekly space to share the correspondence we get from our readers and also for our members to tell us what global development books you are reading.

|Genes bring music to your ears
||Multiple regions in the human genome are reported to be linked to musical aptitude, according to a new study. The function of the candidate genes implicated in the study ranges from inner-ear development to auditory neurocognitive processes, suggesting that musical aptitude is affected by a combination of genes involved in the auditory pathway. The perception of music starts with specialized hair cells in the inner ear, which transmit sounds as electronic signals through the auditory pathway to the auditory cortex, where sounds are primarily recognized. In addition to simple sensory perception, the processing of music has been shown to affect multiple other regions of the brain that play a role in emotion, learning and memory.
|Play it again, Sam: How the brain recognizes familiar music
||Research reveals that the brain's motor network helps people remember and recognize music that they have performed in the past better than music they have only heard. A recent study sheds new light on how humans perceive and produce sounds, and may pave the way for investigations into whether motor learning could improve or protect memory or cognitive impairment in aging populations.

|Substance naturally found in humans effective in fighting brain damage from stroke
||A molecular substance that occurs naturally in humans and rats was found to 'substantially reduce' brain damage after an acute stroke and contribute to a better recovery, according to a newly released animal study. The study was the first ever to show that the peptide AcSDKP provides neurological protection when administered one to four hours after the onset of an ischemic stroke.
|Lack of sleep, stress describe a mother's experience after child's ALL treatment
||Many months after their child's diagnosis and treatment of acute lymphoblastic leukemia (ALL), 46 percent of mothers exhibited symptoms of clinical anxiety and 26 percent of mothers showed depressive symptoms. The researchers chose to work with mothers in this maintenance period of relative stability following treatment so as to avoid making further demands on mothers during the acute period of their child's illness. This allowed them to look at the mid- and longer-term effects of a child's diagnosis on a mother's wellbeing.
