Ketamine: Kan it Kure Depression?
Affective disorders are those disorders of the brain that are characterized by severe and inappropriate shifts in mood or emotion. These shifts are often to extreme ends of the emotional spectrum where an affected individual is constantly full of energy and confidence (mania) or withdrawn, fatigued, and excessively sad with little interest in usually enjoyable activities (depression). Both of these conditions have been observed and recorded in human history for thousands of years but only recently have they been recognized as brain disorders, given names like major depression and bipolar disorder, and treated as medical conditions.
In the past 150 years it has been noted that the onset of depression is occurring at higher rates and at younger ages that ever before. This data could be the result of factors including an increase in patients coming forward to be diagnosed, improved diagnoses, or simply better record keeping. Whatever the reason, it is estimated that 15 to 20% of the population is experiencing symptoms of major depression at any given time, with a greater occurrence in women than in men. Many are affected by this disorder and a cure has yet to be found. But before we continue, a distinction must be made between major depression and “reactive depression” in which a person may feel depressive symptoms because of a single event like the loss of a loved one or a failure of some kind. Major depression is a prolonged state in which an individual may display a number of symptoms including depressed mood, loss of interest in most activity, change in body weight or appetite, changes in sleep patterns, psychomotor agitation or retardation, fatigue, difficulty concentrating, feelings of worthlessness or guilt, and suicidal thoughts. Depending on the severity of the depression a patient may display many, or only a few of these possible symptoms.
