We all experience anxiety. For example, speaking in front of a group can make us anxious, but that anxiety also motivates us to prepare and practice. Driving in heavy traffic is another common source of anxiety, but it helps keep us alert and cautious to avoid accidents. However, when feelings of intense fear and distress become overwhelming and prevent us from doing everyday activities, an anxiety disorder may be the cause. Anxiety disorders are the most common mental health concern in the United States. Over 40 million adults in the U.S. (19.1%) have an anxiety disorder. Meanwhile, approximately 7% of children aged 3-17 experience isses with anxiety each year. Most people develop symptoms before age 21.
SymptomsAnxiety disorders are a group of related conditions, each having unique symptoms. However, all anxiety disorders have one thing in common: persistent, excessive fear or worry in situations that are not threatening. People typically experience one or more of the following symptoms: Emotional symptoms:
- Feelings of apprehension or dread
- Feeling tense or jumpy
- Restlessness or irritability
- Anticipating the worst and being watchful for signs of danger
- Pounding or racing heart and shortness of breath
- Sweating, tremors and twitches
- Headaches, fatigue and insomnia
- Upset stomach, frequent urination or diarrhea
Types Of Anxiety DisordersThere are many types of anxiety disorders, each with different symptoms. The most common types of anxiety disorders include:
Generalized Anxiety Disorder (GAD)GAD produces chronic, exaggerated worrying about everyday life. This worrying can consume hours each day, making it hard to concentrate or finish daily tasks. A person with GAD may become exhausted by worry and experience headaches, tension or nausea.
Social Anxiety DisorderMore than shyness, this disorder causes intense fear about social interaction, often driven by irrational worries about humiliation (e.g. saying something stupid or not knowing what to say). Someone with social anxiety disorder may not take part in conversations, contribute to class discussions or offer their ideas, and may become isolated. Panic attacks are a common reaction to anticipated or forced social interaction.
Panic DisorderThis disorder is characterized by panic attacks and sudden feelings of terror sometimes striking repeatedly and without warning. Often mistaken for a heart attack, a panic attack causes powerful physical symptoms including chest pain, heart palpitations, dizziness, shortness of breath and stomach upset. Many people will go to desperate measures to avoid an attack, including social isolation.
PhobiasWe all tend to avoid certain things or situations that make us uncomfortable or even fearful. But for someone with a phobia, certain places, events or objects create powerful reactions of strong, irrational fear. Most people with specific phobias have several things that can trigger those reactions; to avoid panic, they will work hard to avoid their triggers. Depending on the type and number of triggers, attempts to control fear can take over a person’s life. Other anxiety disorders include:
- Selective mutism
- Separation anxiety disorder
- Substance/medication-induced anxiety disorder, involving intoxication or withdrawal or medication treatment
CausesScientists believe that many factors combine to cause anxiety disorders:
- Genetics. Studies support the evidence that anxiety disorders “run in families,” as some families have a higher-than-average amount of anxiety disorders among relatives.
- Environment. A stressful or traumatic event such as abuse, death of a loved one, violence or prolonged illness is often linked to the development of an anxiety disorder.
DiagnosisPhysical symptoms of an anxiety disorder can be easily confused with other medical conditions, like heart disease or hyperthyroidism. Therefore, a doctor will likely perform an evaluation involving a physical examination, an interview and lab tests. After ruling out an underlying physical illness, a doctor may refer a person to a mental health professional for evaluation. Using the Diagnostic and Statistical Manual of Mental Disorders (DSM) a mental health professional is able to identify the specific type of anxiety disorder causing symptoms as well as any other possible disorders that may be involved. Tackling all disorders through comprehensive treatment is the best recovery strategy.
TreatmentDifferent anxiety disorders have their own distinct sets of symptoms. This means that each type of anxiety disorder also has its own treatment plan. But there are common types of treatment that are used.
- Psychotherapy, including cognitive behavioral therapy
- Medications, including antianxiety medications and antidepressants
- Complementary health approaches, including stress and relaxation techniques
