Anxiety Disorders
Anxiety disorders are a category of mental disorders characterized by feelings of anxiety and fear, where anxiety is a worry about future events and fear is a reaction to current events. These feelings may cause physical symptoms, such as a racing heart and shakiness.
The term anxiety covers four aspects of experiences that an individual may have: mental apprehension, physical tension, physical symptoms and dissociative anxiety. The emotions present in anxiety disorders range from simple nervousness to bouts of terror.
Common treatment options include lifestyle changes, therapy, and medications. Medications are typically recommended only if other measures are not effective.

About Anxiety Disorders
Anxiety disorders are partly genetic but may also be due to drug use including alcohol & caffeine, as well as withdrawal from certain drugs. They often occur with other mental disorders, particularly major depressive disorder, bipolar disorder, certain personality disorders, and eating disorders.
The term anxiety covers four aspects of experiences that an individual may have: mental apprehension, physical tension, physical symptoms and dissociative anxiety. The emotions present in anxiety disorders range from simple nervousness to bouts of terror. There are other psychiatric and medical problems that may mimic the symptoms of an anxiety disorder, such as hyperthyroidism.
There are a number of anxiety disorders including specific phobias; social anxiety disorder; separation anxiety disorder; panic disorder and agoraphobia.
While each has its own characteristics and symptoms, they all include symptoms of anxiety.
Globally as of 2010 approximately 273 million (4.5% of the population) had an anxiety disorder. It is more common in females (5.2%) than males (2.8%).
In Africa, lifetime rates of anxiety disorders are between 9 and 16%, and yearly rates are between 4 and 7%.
Common treatment options include lifestyle changes, therapy, and medications. Medications are typically recommended only if other measures are not effective. Anxiety disorders occur about twice as often in females as males, and generally begin during childhood.

Generalized anxiety disorder (GAD) is a common, chronic disorder characterised by long-lasting anxiety that is not focused on any one object or situation.
Those suffering from generalised anxiety disorder experience non-specific persistent fear and worry, and become overly concerned with everyday matters.
According to Schacter, Gilbert, and Wegner’s book Psychology:
Second Edition, generalised anxiety disorder is “characterised by chronic excessive worry accompanied by three or more of the following symptoms: restlessness, fatigue, concentration problems, irritability, muscle tension, and sleep disturbance”.
Generalised anxiety disorder is the most common anxiety disorder to affect older adults. Anxiety can be a symptom of a medical or substance abuse problem, and medical professionals must be aware of this.
A diagnosis of GAD is made when a person has been excessively worried about an everyday problem for six months or more. A person may find that they have problems making daily decisions and remembering commitments as a result of lack of concentration/preoccupation with worry. Appearance looks strained, with increased sweating from the hands, feet, and axillae, and they may be tearful, which can suggest depression. Before a diagnosis of anxiety disorder is made, physicians must rule out drug-induced anxiety and other medical causes.
In children GAD may be associated with headaches, restlessness, abdominal pain, and heart palpitations. Typically it begins around 8 to 9 years of age.
GAD runs in families and is six times more common in the children of someone with the condition.
While anxiety arose as an adaptation, in modern times it is almost always thought of negatively in the context of anxiety disorders.
People with these disorders have highly sensitive systems; hence, their systems tend to overreact to seemingly harmless stimuli. Sometimes anxiety disorders occur in those who have had traumatic youths, demonstrating an increased prevalence of anxiety when it appears a child will have a difficult future. In these cases, the disorder arises as a way to predict that the individual’s environment will continue to pose threats.
Other common causes include:
Low levels of GABA, a neurotransmitter that reduces activity in the central nervous system, contribute to anxiety. A number of anxiolytics achieve their effect by modulating the GABA receptors. Selective serotonin reuptake inhibitors, the drugs most commonly used to treat depression, are frequently considered as a first line treatment for anxiety disorders.
Anxiety disorders are often severe chronic conditions, which can be present from an early age or begin suddenly after a triggering event. They are prone to flare up at times of high stress and are frequently accompanied by physiological symptoms such as headache, sweating, muscle spasms, tachycardia, palpitations, and hypertension, which in some cases lead to fatigue or exhaustion.
In casual discourse the words “anxiety” and “fear” are often used interchangeably; in clinical usage, they have distinct meanings: “anxiety” is defined as an unpleasant emotional state for which the cause is either not readily identified or perceived to be uncontrollable or unavoidable, whereas “fear” is an emotional and physiological response to a recognized external threat. The term “anxiety disorder” includes fears (phobias) as well as anxieties.
Standardized screening clinical questionnaires such as the Taylor Manifest Anxiety Scale or the Zung Self-Rating Anxiety Scale can be used to detect anxiety symptoms, and suggest the need for a formal diagnostic assessment of anxiety disorder. Anxiety disorders often occur along with other mental disorders, in particular depression, which may occur in as many as 60% of people with anxiety disorders. The fact that there is considerable overlap between symptoms of anxiety and depression, and that the same environmental triggers can provoke symptoms in either condition, may help to explain this high rate of comorbidity.
Studies have also indicated that anxiety disorders are more likely among those with family history of anxiety disorders, especially certain types.
Sexual dysfunction often accompanies anxiety disorders, although it is difficult to determine whether anxiety causes the sexual dysfunction or whether they arise from a common cause. The most common manifestations in individuals with anxiety disorder are avoidance of intercourse, premature ejaculation or erectile dysfunction among men and pain during intercourse among women. Sexual dysfunction is particularly common among people affected by panic disorder (who may fear that a panic attack will occur during sexual arousal) and posttraumatic stress disorder.
Focus is increasing on prevention of anxiety disorders these days, rather than Treatment.
Treatment options available include lifestyle changes, therapy, and medications. Medication are only recommended if other measures are not effective. Stopping smoking has benefits in anxiety as large as or larger than those of medications. Reducing caffeine intake and regular exercise are also useful measures.
There is tentative evidence to support the use of cognitive behavior therapy and mindfulness therapy. But as of today, there are still no effective measures to prevent GAD in adults.
The prognosis varies on the severity of each case and utilization of treatment for each individual.
If these children are left untreated, they face risks such as poor results at school, avoidance of important social activities, and substance abuse.
Children who have an anxiety disorder are likely to have other disorders such as depression, eating disorders, attention deficit disorders both hyperactive and inattentive.
Like adults, children can experience anxiety disorders; between 10 and 20 percent of all children will develop a full-fledged anxiety disorder prior to the age of 18, making anxiety the most common mental health issue in young people.
Anxiety disorders in children are often more challenging to identify than their adult counterparts owing to the difficulty many parents face in discerning them from normal childhood fears.
Likewise, anxiety in children is sometimes misdiagnosed as an attention deficit disorder or, due to the tendency of children to interpret their emotions physically (as stomach aches, head aches, etc.), anxiety disorders may initially be confused with physical ailments.
Anxiety in children has a variety of causes; sometimes anxiety is rooted in biology, and may be a product of another existing condition, such as Autism or Asperger’s Disorder. Gifted children are also often more prone to excessive anxiety than non-gifted children. Other cases of anxiety arise from the child having experienced a traumatic event of some kind, and in some cases, the cause of the child’s anxiety cannot be pinpointed.

Anxiety in children tends to manifest along age-appropriate themes, such as fear of going to school (not related to bullying) or not performing well enough at school, fear of social rejection, fear of something happening to loved ones, etc.
What separates disordered anxiety from normal childhood anxiety is the duration and intensity of the fears involved.
A small child will usually experience separation anxiety, for example, but he or she will generally grow out of it by about the age of 6, whereas in an anxious child it may linger for years longer, hindering the child’s development. Similarly, most children will fear the dark or losing their parents at some point, but this fear will dissipate over time without interfering a great deal in that child’s normal day-to-day activities. In a child with an anxiety disorder, fearing the dark or loss of loved ones may grow into a lasting obsession which the child tries to deal with in compulsive ways which erode his or her quality of life.
Several methods of treatment have been found to be effective in treating childhood anxiety disorders. Cognitive behavioral therapy (CBT), a well-established treatment for anxiety related disorders in children and adolescents, is a good first therapy approach.
Studies have also gathered substantial evidence for treatments that are not CBT based as being effective forms of treatment, expanding treatment options for those who do not respond to CBT. Like adults, children may undergo psychotherapy, cognitive-behavioral therapy, or counseling.
