Post-Traumatic Stress Disorder (PTSD) is a common and severe psychiatric disorder precipitated by exposure to a psychologically distressing event. PTSD is associated with significant morbidity and mortality and is characterised by the presence of three distinct, but co-occurring, symptom clusters. Research evidence suggests that PTSD has a neurobiological basis. Current research on the neurobiology of PTSD include the utilisation of functional brain imaging; molecular genetic research; and, the incorporation of cross-system research including neuroendocrine, neurochemical, and neuroimmunological systems. This book examines the neurobiological basis of PTSD and the future research goals in regards to these findings.

Terrorism is a form of warfare that has become a global concern in the contemporary world. Terrorism has been practised by a broad array of political organisations for furthering their objectives. Terrorism has existed since the beginning of the history of mankind. Terrorist attacks took place practically in every country in the world. Terrorism is usually a planned, purposeful and premeditated, man made violent act, which is in fact a form of psychological warfare to intimidate people. Terrorist attacks are carried out in such a way as to maximise the severity and length of the psychological impact. This book is mostly dedicated to suicidal terrorism. The impact of terrorist attacks on suicidal behaviour in the general population is also discussed. This book is of interest to physicians, psychologists, other clinicians, and experts in public health management.

Immigrants' voyages to a new land have been among the most exciting and noble of human endeavours. It is the amazing courage to flee oppression, to leave behind everything that is familiar, and to chance the hostility of a completely alien culture in order to find freedom, opportunity, and a better life. Immigrants often face difficulty adjusting to their new home in a new country for many reasons, including coping with trauma experienced in their native country, overcoming cultural and language barriers, and encountering discrimination. This can lead to severe and long-lasting psychological and behavioural problems, including depression, anxiety, post-traumatic stress disorder and a high risk for suicide.
