Through music we can learn much about our human origins and the human brain. Music is a potential method of therapy and a means of accessing and stimulating specific cerebral circuits. There is also an association between musical creativity and psychopathology. This paper provides a brief review.

Music is a universal human trait. The healing power of music has been acknowledged in almost all traditions of music. Music therapy is moving from a social-science model focusing on overall health and well-being towards a neuroscience model focusing on specific elements of music and its effect on sensorimotor, language and cognitive functions. The handful of evidence-based music therapy studies on psychiatric conditions have shown promising results. Traditional music, such as Indian classical music, has only recently been evaluated in evidence-based research into music therapy. The need for systematic research in this area is underscored.

When pursued professionally, the demands of musical training and performance can interfere with musicians' well-being and health. Music performance anxiety, while energising at optimal levels, impairs performance quality when excessive. A range of interventions has been explored to address it. However, the poor methodological quality of such studies and the complexity of this issue should mobilise further research resources in this direction.

Sri Lanka's civil war and the tsunami in 2004 had enormous psychological impacts on the country's children. Tackling these issues has been difficult due to the lack of specialists in child and adolescent psychiatry. The end of the war in 2009 opened new avenues for the development of mental health services for children and youth in Sri Lanka. The year 2016 was historic in that the first board-certified child and adolescent psychiatrists assumed services in the country, after training in Australia.

In 2012 Ghana passed a new Mental Health Act, which aimed to create a new system of mental healthcare in Ghana. The Act includes provisions for the creation of a modern, community-based mental health system and for the protection of the rights of persons with mental disorders. This article discusses the implications of the Act and the progress which has been made towards its implementation.

In the Islamic Republic of Pakistan the law relating to people who are mentally ill, until 2001, was set out by the Lunacy Act of 1912, which was inherited from the British colonial occupiers. In 2001 the Mental Health Ordinance 2001 took its place but only for this federal law to be superseded in April 2010 with the 18th constitutional amendment. As part of that amendment, provinces have become responsible for (psychiatric) healthcare, including mental health legislation. Forensic psychiatry is practised in Pakistan but is very much in its infancy; it needs to develop and learn from more experienced countries in Europe and North America. Cultural factors and misconceptions arising from religion can at times contribute to, or create, barriers to the implementation of forensic psychiatric services in Pakistan. This paper reviews the current state of forensic psychiatric services in Pakistan and is intended to open the debate on the challenges ahead.

The National Continuing Management and Intervention Programme for Psychoses, also known as the 686 Programme, was launched in China in 2004, marking a shift to a hospital-and-community collaborative model of care for patients with psychoses. An updated programme, the National Comprehensive Management Pilot Project for Mental Health, was launched in 2015 with the cooperation of six government ministries and bodies, including the China Disabled Persons Federation. Mechanisms for multi-sector cooperation in mental health services are being put in place in China.

I visited Chile for the first time in 2003. Over the course of the 12 months during which the country became my home, I realised there was a secret side to the capital city, Santiago. Never was this clearer than when I witnessed a demonstration to mark the 30th anniversary of the 11 September 1973 coup, when General Pinochet took power. I watched tears stream down the cheeks of men and women as they sang along with the revolutionary Cuban folk singer Silvio Rodriguez, raising their fists in the air. I felt the distrust of and anger towards the police who lined rooftops with snipers and the military units which filled side streets with water cannons. It was a visceral experience, made more so by the contrast with day-to-day life on the city's streets. This was a boom town, proud of its malls and economic growth, and the residents of Santiago made every effort to remark upon their high standards of living.

More than a year ago I was sat in my room watching an American university professor demonstrating a computerised test on a tablet to one of his interns. His name was Matthew Nock and he was a professor of psychology at Harvard University and a world expert on suicide research. The computerised test was and still is called the Suicide Implicit Association Test (S-IAT) and Professor Nock hoped he was on the brink of a breakthrough in suicide risk prediction research. I was sceptical. How could a brief computerised test predict future suicide attempts better than already known suicide risk factors and the expert opinion of a psychiatrist? It was at this moment that I was convinced that I would have to spend some time in Professor Nock's lab at Harvard in order to get the inside story.
