Personal injury info:

PTSD is a well-known mental health consequence of trauma. However, it is only one of many psychiatric conditions that may result from the psychological impact of trauma. As an expert witness, it is important to be able to diagnose PTSD in all its forms. Equally important is the ability to establish the link between PTSD and the many long-term consequences of trauma that may take the form of other more common mental illnesses.

My area of expert witness spans the whole of adult mental health and includes:

Personal injury.
Mental disorder in criminal justice proceedings – fitness to plead, fitness to stand trial, sentencing.
Mental disorder in in civil proceedings – includes capacity to make decisions.
Independent second opinion in any matter of adult mental health.
