Posttraumatic Stress Disorder

 POST TRAUMATIC STRESS DISORDER 

Posttraumatic stress disorder can occur in a person who has witnessed an extraordinarily terrifying and potentially deadly event. After the traumatic event, the person reexperiences all or some of it through dreams or wak-ing recollections and responds defensively to these flash-backs. New behaviors develop related to the trauma, such as sleep difficulties, hypervigilance, thinking diffi-culties, severe startle response, and agitation (APA, 2000;).

Anorexia Nervosa

Image
  ANOREXIA NERVOSA   Onset and Clinical Course   Anorexia nervosa typically begins between 14 and 18 years of age. In the early stages, clients often deny they have a neg-ative body image or anxiety regarding their appearance. They are very pleased with their ability to control their weight and may express this. When they initially come for treatment, they may be unable to identify or to explain their emotions about life events such as school or relationships with family or friends. A profound sense of emptiness is common.   As the illness progresses, depression and lability in mood become more apparent. As dieting and compulsive behaviors increase, clients isolate themselves. This social isolation can lead to a basic mistrust of others and even paranoia. Clients may believe their peers are jealous of their weight loss and may believe that family and health care professionals are trying to make them “fat and ugly.”   In long-term studies of clients with anorexia...

Bulimia - Eating Disorders

  Onset and Clinical Course   Bulimia nervosa usually begins in late adolescence or early adulthood; 18 or 19 years is the typical age of onset. Binge eating frequently begins during or after dieting. Between binging and purging episodes, clients may eat restrictively, choosing salads and other low-calorie foods. This restric-tive eating effectively sets them up for the next episode of binging and purging, and the cycle continues.   Clients with bulimia are aware that their eating behav-ior is pathologic and go to great lengths to hide it from others. They may store food in their cars, desks, or secret locations around the house. They may drive from one fast-food restaurant to another, ordering a normal amount of food at each but stopping at six places in 1 or 2 hours. Such patterns may exist for years until family or friends discover the client’s behavior or until medical complica-tions develop for which the client seeks treatment.   Follow-up studies with clients w...

Tasks of Grieving

  Tasks of Grieving   Grieving tasks , or mourning, that the bereaved person   faces involve active rather passive participation. It is some-times called “grief work” because it is difficult and requires tremendous effort and energy to accomplish.   Rando (1984) describes tasks inherent to grieving that she calls the “six R’s”:   ·      Recognize:  Experiencing the loss, and understanding   that it is real, it has happened.   ·      React:  Emotional response to loss, feeling the feelings.   ·      Recollect and re-experience:  Memories are reviewed and   relived.   ·      Relinquish:  Accepting that the world has changed (as a   result of the loss), and there is no turning back.   ·      Readjust:  Beginning to return to daily life; loss feels less   acute and overwhelming.   ·   ...
