Besides fight and flight responses, animals and humans may respond to threat with freezing, a response characterized by bradycardia and physical immobility. Risk assessment is proposed to be enhanced during freezing to promote optimal decision making. Indeed, healthy participants showed freezing-like responses to threat cues. Posttraumatic stress disorder (PTSD) patients are characterized by hypervigilance and increased threat responsiveness.

Good sleep is important for our emotional stability and aggression control. Although most people do not become violent after a period of poor sleep, this may be different for certain vulnerable individuals. Forensic psychiatric patients may represent a group of such individuals. We studied patients who committed a crime, often violent in nature, but are not completely held accountable for this due to a mental disorder. They usually get sentenced by the court to follow treatment.

For the past six years, children in Syria have been bombed and starved. They have seen their friends and families die before their eyes or buried under the rubble of their homes. They have watched their schools and hospitals destroyed, been denied food, medicine and vital aid, and been torn apart from their families and friends as they flee the fighting. Every year that the war goes on plumbs new,  previously unimaginable depths of violence against children, and violations of international law by all sides.

The second comprises work-related interactions such as those with fellow team members. The third are ethical challenges as a result of interactions with the home front.
