Common Experience
Minor trauma is a part of everyday life
For most people these injuries are only transient
Some have psychiatric and social complications
Most people experience major trauma at some time in their lives
Psychological Behavioural, and Social factors

Consequences for work, leisure, and family life
Disability may become greater than might be expected from the severity of
physical injuries alone

Immediate Effects of Frightening Trauma
Anxiety, numbness, dissociation and sometimes inappropriate calmness
“Innocent victims” often angry and frustrated
“Acute Stress Disorder" is now used
Occurs in 20-50% of those who have suffered major trauma
The severity of emotional symptoms is much more closely related to how
frightening the trauma was than to the severity of the injury
Even uninjured victims may suffer considerable distress
Severe distress is usually temporary but indicates a risk of long term post
traumatic symptoms

History
Associated most with Disasters and Warfare
Not new - 6th Century BC
Every conflict since American Civil War in 1863
“Shell-Shock”
“Battle Fatigue”
“Combat Syndrome”
THIS IS NOT GULF WAR SYNDROME
History
40 Conflicts in world at any one time
1% of world pop are refugees
American Civil War – “Nostalgia”
More casualties than dysentery
WWI
13,000 cases of “shell shock” in Brits
200,000 cases by 1918
Case History 1
During active service in Northern Ireland the patient was involved in a
helicopter crash. The patient was strapped in but the blood and brains of his
"best mate" spattered him. Four months of psychological help was deemed
successful. Later, in the Gulf war, observation of troop transport helicopters
awakened his memories of the incident. He carried on successfully until he
was demobilised in 1994, when the support of regimental camaraderie was
lost. Helicopter transport of troops in a film, Bravo 2 Zero, forced his mind
back to the crash. Subsequently any reference to helicopters led to reexperiencing the trauma. The diagnosis of post-traumatic stress disorder was
straightforward when his military history was taken as part of an assessment
of fatigue, impaired memory, nocturnal sweating, rashes, musculoskeletal
aches, dyspnoea, and dyspepsia.
Case History 2
A young nurse was woken by a missile exploding to her left. Terrified and
claustrophobic she vomited and evacuated her bowel and bladder. Her
protective kit could not be removed until tests allowed the all clear to be
sounded about five hours later. She became too frightened to shower because
being naked would have prevented her running to a shelter. She took
accelerated discharge from the air force. She could not keep jobs because of
poor time keeping, irascibility, and disproportionate emotional responses to
minor adversity. Distressing recall of terrified anticipation of her death
occurred by day and night. She developed fatigue and anorexia and solitary
alcohol bingeing. She became claustrophobic when shopping or on public
transport where she vomited and screamed. Civilian consultations proved
unhelpful because no one asked about her experiences during the conflict to
learn the origins of her dysfunction.
Case History 3
A major aged 37 years directed some of the clear up of battle field carnage. He
saw and smelled many remains of Iraqi people but thought that he was not
affected. He became uncommunicative but irritable; his love of life and the
army diminished. Two years after his early retirement he saw a television
documentary on the Gulf and dramatically recalled the events of six years
previously. The smell of off-fresh chicken meat focused memories of rotting
flesh. Repeated recall of half-burnt Iraqi corpses forced him to re-experience
the initiating trauma. His nightmares, insomnia, poor memory, fatigue, and
irascibility became worse, and he developed headaches, musculoskeletal
aches, and dyspepsia. His decision making and attendance at work suffered.
General medical and rheumatological consultations were unhelpful. Posttraumatic stress disorder was diagnosed only after his battlefield and
psychiatric histories were considered. Many symptoms had not previously
been discussed. His wife felt "trapped in a tunnel with no lights" and
commented "I wish this Rupert could go to the Gulf and bring my old Rupert
back . . . I don't know how to help him."

World War 1 and Developments
Shell Shock recognised by War Office – 1916
(Charles Myers)
Acute incapacity NOT beyond their control
307 troops executed for cowardice
80,000 cases
80% of cases never returned to active duty
1918 - 15,000 still hospitalised
World War 1 and Developments
Ernest Jones (president of British Psycho-Analytic Association)
“An official abrogation of civilised standards' in which men were not only
allowed, but encouraged...to indulge in behaviour of a kind that is
throughout abhorrent to the civilised mind. All sorts of previously
forbidden and hidden impulses, cruel, sadistic, murderous and so on, are
stirred to greater activity, and the old intrapsychical conflicts which,
according to Freud, are the essential cause of all neurotic disorders, and
which had been dealt with before by means of 'repression' of one side of
the conflict are now reinforced, and the person is compelled to deal with
them afresh under totally different circumstances.”

Psychological Consequences of Trauma
Acute anxiety, numbing, arousal (acute stress disorder)
Pain and apparently disproportionate disability
Anxiety disorder
Unexplained physical symptoms
Major depressive disorder
Impact on family (such as family arguments, depression in family members)
Post-traumatic symptoms and disorder
Avoidance and phobic anxiety
Types of Modern Trauma
Occupational
Return to work often slower than in other types of injury
Liaison with employer essential
Compensation issues may impede return to work
Sporting
May be associated with physical unfitness or with inappropriate activity for
age
Domestic
Assess role of alcohol, consider possible family and other problems, assess
risk of further incidents
Disasters
Fear of unpredictability and lack of control
Types of Modern Trauma
Assault (including sexual)
Assess role of alcohol, keep detailed records, suggest availability of help for
major, and especially for sexual, assault
Road traffic crash
Psychological complications may occur even if no significant physical injury.
Whiplash injuries should be treated by well planned mobilisation and
encouragement, together with alertness to possible psychological
complications

Childhood Trauma as cause of ADHD
“Disease” camp vs. “Environmental” camp
Can certain circumstances increase chances of ADHD?
522 children aged 6 - 17
280 ADHD
242 Comparisons
Early childhood trauma was a cause
Boys more functionally impaired than girls
Low social class made ADHD more likely
Maternal smoking made ADHD more likely
Greatest risk factor was family conflict
Bierderman et al. 2002
Mumme - 1 yr olds!
PTSD survivors see emotions differently
Experience can alter perceptions of emotion
Pollak et al. 2002
Studied abuse survivors (8-10 yrs)
Faces with morphed photos - combination of emotions

“Male victims of sexual abuse 3 times more likely to suffer health
problems”
93 boys abused by same teacher

PTSD Markers of Self-Harm
DSH (Parasuicide)
intentional, non-suicide, non-life threatening act
Female: Male 2:1
At risk:
15-24 biggest group
Female
Isolation
Negative life events bereavement abuse
Pre-existing psychiatric conditions
Family history of DSH
Intolerable stress
Impulsive, Immature, Aggressive personality
PTSD Markers of Self-Harm - Methods
• Cutting
Forearms and wrists
Legs and feet
Laterality
Genitalia (abuse survivors)
• Burning
• Pills and Toxins (detection)
5th biggest cause of hospital admissions in UK
PTSD Markers of Self-Harm – Pre-Meditation
Premeditation can be biggest sympathy inhibitor
• Saving up pills / blades
• Avoiding discovery
• Long sleeves
• Prepared excuse stories
• Bandage stockpiles
PTSD Markers of Self-Harm – Motivation
• Cry for help
have they talked to anyone prior to DSH?
• Escape from situation
control & mastery
• Punishment and Manipulation of others
loved ones
failing relationships
inferiority
Factitious Injury
Feigned physical / psychological symptoms or signs
Aim is to receive medical care
Most are female, “stable” networks, many working in healthcare
Only confront if evidence of factitious harm is established
Supportive confrontation:
aware of role of behaviour in their
illness
offer psychological help with this
Patients usually stop behaviour but leave clinic
Offer of psychiatric care rarely taken up
Cognitive Behavioural Strategies for PTSD
Talking it through
Encourage victim to discuss and relive feelings about the incident
Tackling avoidance
Discuss graded increase in activities, such as return to travel after a road crash
Coping with anxiety
Anxiety management techniques (relaxation, distraction)
Dealing with anger
Encourage discussion of incident and of feelings
Overcoming sleep problems
Emphasise importance of regular sleep habits and avoidance of excessive
alcohol and caffeine
Treat associated depression
Antidepressant drugs, limited role for hypnotics immediately after
Summary
“Acute Stress Disorder” more accurate
Traumatic events can occur any time or place
Incapacity in face of fear and terror is natural
Reactions can be immediate or delayed or both
Delayed reactions triggered by any associations
PTSD was a political diagnosis
Resulted in over-reporting of effects in Vietnam vet population
PTSD Diagnoses not objective
PTSD lacks precision
