Post traumatic stress disorder
1. • Classified as an anxiety disorder.
• After trauma exposes the victim to actual or threatened
death or serious injury, 3 dimensions of PTSD unfold:
(1) reexperiencing the event with distressing
recollections, dreams, flashbacks, and/or psychologic
and physical distress;
(2) persistent avoidance of stimuli that might invite
memories or experiences of the trauma; and
(3) increased arousal
(Vieweg et al, 2006)

3. • Research into the pathophysiology of PTSD has
focussed on areas of the brain associated with
fear processing and memory:
- Amygdala, Hippocampus, Medial prefrontal
cortex
• There is still uncertainty over the patho-
physiology of PTSD.
• Hypothesised that PTSD represents a failure of
the prefrontal-anterior networks to regulate the
amygdala – resulting in hyper-reactivity to
threat.

5. 1) genetic factors and gene by environment
interactions;
2) developmental/childhood factors;
3) neurobiological risk and resilience factors;
4) psychological risk and resilience factors (e.g.,
coping style, personality);
5) cognitive/behavioral risk and resilience factors
(e.g., processing information and appraisal of
information);
6) social factors.

6. Through this session you have:
• Considered and practically utilised relevant
outcome measures to identify common mental
health conditions.
• Gained a brief overview of the pathophysiology
of common mental health conditions.
• Discussed the practical application of this
knowledge to physiotherapy practice.
• Considered other influences on individuals
mental and emotional health.
