PTSD
PTSD, or post-traumatic stress
disorder, leapt to the public’s consciousness when the American Psychiatric
Association added the health issue to its diagnostic manual of mental disorders
in the 1980s. But PTSD—known to previous generations as shell shock, soldier’s
heart, combat fatigue or war neurosis—has roots stretching back centuries and
was widely known during ancient times.
PTSD Symptoms
Post-traumatic stress disorder is
a mental health condition that occurs when someone witnesses or experiences a
severely traumatic event. This can include war or combat, serious accidents,
natural disasters, terrorism, or violent personal assaults, such as rape. People
with the disorder may experience PTSD symptoms such as frequent fear, stress,
and anxiety stemming from the traumatic event. They may relive the event
through flashbacks or nightmares and have intense, disturbing thoughts and
feelings related to the event. They sometimes avoid people, places and
situations that remind them of the trauma. They may also experience increased
arousal and reactive symptoms, such as feeling jumpy (startling easy), having
problems concentrating or sleeping, being easily angered or irritated and
engaging in reckless or self-destructive behavior.
What Is PTSD?
It’s not entirely known what
causes PTSD to develop, but it may be related to the stress hormones. That is,
traumatic events put the body into a survival “fight or flight” mode, in which
body releases stress hormones (adrenaline and norepinephrine) to provide a
burst of energy while pausing some of the brain’s other tasks, such as filling
short-term memories. People with PTSD continue to produce high amounts of these
hormones outside of dangerous situations and their amygdala—the part of the
brain that handles fear and emotion—is more active than people without PTSD. Over
time, PTSD changes the brain, including by causing the part of the brain that
handles memory (the hippocampus) to shrink.
PTSD in Epics and Classics
Long before the dawn of modern
psychiatry, people and situations depicting PTSD may have been recorded in
early works of literature. For example, in the Epic of Gilgamesh, the earliest
surviving major work of literature (dating back to 2100 B.C.), the main
character Gilgamesh witnesses the death of his closest friend, Enkidu.
Gilgamesh is tormented by the trauma of Enkidu’s death, experiencing recurrent
and intrusive recollections and nightmares related to the event. Later, in a
440-B.C. account of the battle of Marathon, Greek historian Herodotus describes
how an Athenian named Epizelus was suddenly stricken with blindness while in
the heat of battle after seeing his comrade killed in combat. This blindness,
brought on by fright and not a physical wound, persisted over many years. Other
ancient works, such as those by Hippocrates, describe soldiers who experienced
frightening battle dreams. And outside of Greco-Latin classics, similar
recurrent nightmares also show up in Icelandic literature, such as Gísli
Súrsson Saga. In the Indian epic poem Ramayana, likely composed around 2,500
years ago, the demon Marrich experiences PTSD-like symptoms, including
hyper-arousal, reliving trauma, and avoidance behavior, after nearly being
killed by an arrow. Marrich also gave up his natural duty of harassing monks
and became a meditating recluse.
Nostalgia and Soldier’s Heart
In the last several hundred
years, medical doctors have described a few PTSD-like illnesses, particularly
in soldiers who experienced combat. In the late 1600s, Swiss physician Dr.
Johannes Hofer coined the term “nostalgia” to describe Swiss soldiers who
suffered from despair and homesickness, as well as classic PTSD symptoms like
sleeplessness and anxiety. Around the same time, German, French and Spanish
doctors described similar illnesses in their military patients. In 1761,
Austrian physician Josef Leopold Auenbrugger wrote about nostalgia in
trauma-stricken soldiers in his book Inventum Novum. The soldiers, he reported,
became listless and solitary, among other things, and efforts could do little
to help them out of their torpor.
PTSD in the Civil War
Nostalgia was a phenomenon noted
throughout Europe and the “disease” reached American soil during the U.S. Civil
War (1861–1865). In fact, nostalgia became a common medical diagnosis that
spread throughout camps. But some military doctors viewed the illness as a sign
of weakness and one that only affected men with a “feeble will”—and public
ridicule was sometimes the recommended “cure” for nostalgia. While nostalgia
described changes in veterans from a psychological perspective, other models
took a physiological approach. After the Civil War, U.S. doctor Jacob Mendez Da
Costa studied veterans and found that many of them suffered from certain
physical issues unrelated to wounds, such as palpitations, constricted
breathing, and other cardiovascular symptoms. These symptoms were thought to
arise from an overstimulation of the heart’s nervous system, and the condition
became known as “soldier’s heart,” “irritable heart,” or “Da Costa’s syndrome.”
Interestingly, PTSD-like symptoms weren’t restricted to soldiers in the 1800s.
During the Industrial Revolution, rail travel became more common—as did railway
accidents. Survivors of these accidents displayed various psychological
symptoms (anxiety and sleeplessness, for instance), which collectively became
known as “railway spine” and “railway brain” because autopsies suggested
railway accidents caused microscopic lesions to the central nervous system.
Shell Shock
Post-traumatic stress disorder
was a major military problem during World War I, though it was known at the
time as “shell shock.” The term itself first appeared in the medical journal
The Lancet in Feb. 1915, some six months after the “Great War” began. Capt.
Charles Myers of the Royal Army Medical Corps documented soldiers who
experienced a range of severe symptoms—including anxiety, nightmares, tremor,
and impaired sight and hearing—after being exposed to exploding shells on the
battlefield. It appeared that the symptoms resulted from a kind of severe concussion
to the nervous system (hence the name). By the following year, however, medical
and military authorities documented shell shock symptoms in soldiers who had
been nowhere near exploding shells. These soldiers’ conditions were considered
neurasthenia—a type of nervous breakdown from war—but was still encompassed by
“shell shock” (or war neurosis). There were some 80,000 cases of shell shock in
the British army alone by the end of the war. Soldiers often returned to the
war zone after only a few days’ rest, and those who were treated for longer
periods of time sometimes underwent hydrotherapy or electrotherapy. In World
War II, British and American described traumatic responses to combat as “battle
fatigue,” “combat fatigue” and “combat stress reaction”—terms that reflected
the belief that the conditions were related to long deployments. Up to half of
military discharges during the war may have been related to combat exhaustion,
according to the National Center for PTSD.
Modern-Day PTSD
In 1952, the American Psychiatric
Association (APA) added “gross stress reaction” to its first Diagnostic and
Statistical Manual of Mental Disorders, or DSM-I. The diagnosis related to
psychological issues stemming from traumatic events (including combat and
disasters), though it assumed that the mental health issues were short-lived—if
the problem lasted for more than 6 months, then it was thought that it had nothing
to do with wartime service. In the DSM-II, published in 1968, the APA removed
the diagnosis but included “adjustment reaction to adult life,” which did not
efficiently capture PTSD-like symptoms. This removal meant that many veterans
who suffered from such symptoms weren’t able to receive the proper psychological
help that they needed. Drawing on research involving people who survived
severely traumatic events, including war veterans, Holocaust survivors and
sexual trauma victims, the APA included post-traumatic stress disorder in the
DSM-III (1980). The diagnosis drew a clear distinction between traumatic events
and other painful stressors, such as divorce, financial hardships and serious
illnesses, which most individuals are able to cope with and don’t produce the
same symptoms. The diagnostic criteria for PTSD was revised in the DSM-IV
(1994), and DSM-IV-TR (2000), and DSM-5 (2013) to reflect ongoing research. In
the DSM-5, PTSD is no longer considered an anxiety disorder because it’s
sometimes associated other mood states (depression), as well as angry or
reckless behavior; it’s now in a category called Trauma- and Stressor-Related
Disorders.
Today, about 7.7 million American
adults have PTSD, according to the Anxiety and Depression Association of
America.
