Introduction Anxiety is a condition caused by a feeling of fear and tension, and it may be accompanied by headaches, chest pains, shaking among others. Generalized Anxiety Disorder (GAD) is one of the disorders that are accompanied by anxiety. In this disorder, anxiety is normally high and frequent, with stress accumulating from work and home cores as a result of minor issues. Symptoms of GAD include restlessness, irritability, tiresomeness, insomnia (which entails difficulty in sleeping), and poor concentration. The main causes of GAD may vary from a stressful experience in life such as a family crisis, traumas from childhood experiences such as a parent’s death, and in some cases, it is hereditary (Bourne, 2005, pp 31). Phobia is also an anxiety disorder that is hereditary in most cases; in such cases, parents tend to be overly concerned and tend to caution their children on almost everything. For instance, they may insist that the child should not play in the rain since he will catch a cold, he should not watch television too much to avoid ruining his eyes, and they are always repeating the don’ts. As a result, the child views the world as a very dangerous place, hence developing a phobia. Nevertheless, this disorder is treatable through benzodiazepine tranquilizers among other prescribed medication, as well as therapy (Bourne, 2005, pp 42). Other types of anxiety disorder include panic disorder, social anxiety disorder, and obsessive-compulsive disorder. Brief description of posttraumatic stress disorder (PTSD) Posttraumatic stress disorder (earlier referred to as combat fatigue) can be caused by a terrifying experience in which harm was either caused or threatened to the patient. PTSD was diagnosed by soldiers who suffered from traumas after wars. Such experiences may be natural disasters like the tsunami and accidents. Patients with PTSD normally have memories of these events, which disturb them emotionally and mentally. They also experience problems in sleeping and often want to be alone. According to Edwards (2011), PTSD appears in 7-8% of people especially in rape victims and in teenagers who have experienced their parents being killed or community violence. The article further adds that those people who are addicted to smoking marijuana and taking alcohol normally develop PTSD. The main symptoms of this disorder are reoccurring traumas like flashbacks and nightmares and memories. The patient normally develops a phobia of some places and avoid them especially if they are a constant reminder of the trauma. Constant anger and blackouts are common, and in severe cases, a person may attempt suicide. Used therapy approaches and their effectiveness Recommended medication According to Bourne (2005, pp 42), Benzodiazepine tranquilizers, which include Ativan and Klonopin are proven to be effective in treating anxiety disorders, as proof shows that there is a system of the brain that is sensitive to this medication. Hence, when gamma-aminobutyric acid (GABA) is induced to the patients, their anxiety decreases. Prazosin used in PTSD cases has also been proven effective. Therapies used and their effectiveness In the case of treating posttraumatic stress, the psychotherapy technique is used, which involves educating the patients on the disorder, and what they should expect in the treatment process. This technique is designed to minimize myths
