Cognitive Disorders

 Cognitive Disorders

COGNITION IS THE BRAIN’S ability to process, retain, and use information. Cognitive abilities include reasoning, judgment, perception, attention, comprehension, and memory. These cognitive abilities are essential for many important tasks, including making decisions, solving problems, in-terpreting the environment, and learning new information.

 

A cognitive disorder is a disruption or impairment in these higher-level functions of the brain. Cognitive disorders can have devastating effects on the ability to function in daily life. They can cause people to forget the names of immediate family members, to be unable to perform daily house-hold tasks, and to neglect personal hygiene (Davis, 2005).

 

The primary categories of cognitive disorders are delirium, dementia, and amnestic disorders. All involve impairment of cognition, but they vary with respect to cause, treatment, prognosis, and effect on clients and fam-ily members or caregivers. It emphasizes not only the care of clients with cognitive disorders but also the needs of their caregivers.

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

Image
  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.   ·   ...
