Module 48: Anxiety Disorders
What are the different anxiety disorders?
Generalized anxiety disorder – in which a person s unexplainably and continually tense and uneasy
Panic disorder – in which a person experiences sudden episodes of intense dread
Phobias – in which a person is intensely and irrationally afraid of a specific object, activity, or situation
Obsessive-compulsive disorder – in which a person is troubled by repetitive thoughts and/or actions
Post-traumatic stress disorder – in which a person has lingering memories, nightmares, and other
symptoms for weeks after a severely threatening, uncontrollable event.
Generalized Anxiety Disorder: unfocused, out-of-control, negative feelings; lasting 6 months or more; worry
continually; jittery, agitated, sleep-deprived. The anxiety is free-floating, often accompanied by depressed mood,
may lead to physical problems such as high blood pressure. By age 50, GAD becomes fairly rare.
Panic Disorder: anxiety tornado, strikes suddenly, wreaks havoc, and disappears. 1 in 75 have this disorder, panic
attack – a minutes-long episode of intense fear that something horrible is about to happen. Heart palpitations,
shortness of breath, choking sensations, trembling, dizziness – may be misperceived as a heart attack or other
serious physical ailment. Smokers doubled the risk.
Phobias: anxiety disorders in which an irrational fear causes the person to avoid some object, activity, or situation.
Thunderstorms, animals, heights, blood, close spaces. Social phobia is shyness taken to an extreme – an intense
fear of being scrutinized by others, avoid potentially embarrassing social situations or will sweat or tremble when
doing so. If the fear is intense enough, it may become agoraphobia – fear or avoidance of situations in which
escape might be difficult or help unavailable when panic strikes. Charles Darwin – panic disorder at age 28.
Obsessive-Compulsive Disorder: we all may at times be obsessed with senseless or offensive thoughts that will not
go away. 2-3% cross the line with normal checking and obsessive checking. OCD is more common among teens
and young adults than among older people. Studies found that obsessions and compulsions had gradually
lessened though only 1 in 5 had completely recovered.
Common Obsessions and Compulsions Among Children and Teens with OCD
Obsessions (repetitive thoughts)
Concern with dirt, germs, or toxins – 40%
Something terrible happening (fire, death, illness) – 24%
Symmetry, order, or exactness – 17%
Compulsions (repetitive behaviours)
Excessive hand washing, bathing, toothbrushing or grooming – 85%
Repeating rituals (in/out of a door, up/down from a chair) – 51%
Checking doors, locks, appliances, car brakes, homework – 46%
Post-Traumatic Stress Disorder: Our memories exits in part to protect us in the future. So there is biological
wisdom in not being able to forget our most emotional and traumatic experiences – our greatest embarrassments,
our worst accidents, our most horrid experiences. Recurring haunting memories and nightmares, a numbed social
withdrawal, jumpy anxiety, insomnia – shellshock or battle fatigue – now PTSD. Reported by survivors of accidents,
disasters, violent and sexual assaults; 9/11 – 8.5% suffered PTSD of Manhattan residents, 20% who lived near
World Trade Centre. 19% of all Vietnam vets, 1 in 6 US combat infantry of Iraq war; 1 in 4 diagnosed with a
psychological disorder. The greater one’s emotional distress during a trauma, the higher the risk for PT symptoms.
PTSD doubled for survivors who were in the World Trade Centre. A sensitive limbic system seems to increase
vulnerability, by flooding the body with stress hormones again and again as images of the traumatic experience
erupt into consciousness. Brain scans of PTSD patients suffering memory flashbacks reveal an aberrant and
