Hi Mothball,
I practice psychiatric medicine and am a Vietnam combat vet (101st Airborne Division & 173rd Airborne Brigade; 06/68-09/69).
Per the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition,
Text Revision, (DSM-IV-TR), 17 possible symptoms that can develop following the
experience of a traumatic event are divided into three clusters.
Re-Experiencing Symptoms
-Frequently having upsetting
thoughts or memories about a traumatic event.
-Having recurrent
nightmares.
-Acting or feeling as though the traumatic event were
happening again, sometimes called a "flashback."
-Having strong feelings
of distress when reminded of the traumatic event.
-Being physically
responsive, such as experiencing a surge in your heart rate or sweating, to
reminders of the traumatic event.
Avoidance Symptoms
-Making an effort to avoid thoughts, feelings, or conversations about
the traumatic event.
-Making an effort to avoid places or people that
remind you of the traumatic event.
-Having a difficult time remembering
important parts of the traumatic event.
-A loss of interest in
important, once positive, activities.
-Feeling distant from others.
-Experiencing difficulties having positive feelings, such as happiness
or love.
-Feeling as though your life may be cut short.
Hyperarousal Symptoms
-Having a difficult time falling or
staying asleep.
-Feeling more irritable or having outbursts of anger.
-Having difficulty concentrating.
-Feeling constantly "on guard"
or like danger is lurking around every corner.
-Being "jumpy" or easily
startled.
Clearly many of these could pose a significant danger to
diving.
All divers must show attention, concentration, decision making
capacity, impulse control and behavioral modulation that are fully adequate to
meet the demands of scuba. These faculties may be compromised in persons
diagnosed with PTSD and treated with mood stabilizers such as the SSRI citalopram (Celexa) and the anti-convulsant divalproex sodium
(Depakote).
Before returning to SCUBA, it would be prudent that: (a)
mental status examination demonstrates the condition(s) to be well controlled;
(b) the diver who is taking medication(s) has been on them for an extended
period and side effects dangerous to scuba are neither reported nor observed
upon careful examination; (c) there are no other contraindications, mental or
physical, in the clinical picture; (d) the diver feels he is up to it and fully
comprehends any additional risks; (e) the diver has been cleared for diving by
his physician and makes full disclosure to the dive op (which likely will want
to see written clearance) and to his/her dive buddy.
Best of luck and thanks for serving our country.
