ANXIETY AND DEPRESSION
Anxiety and depression can thus co-exist. When this happens one speaks of a depressive-anxiety disorder, which is a form of mild depression accompanied by the symptoms of anxiety. In this disturbance, besides a lowering of mood, which will cause all of the consequences listed above, the predominant symptom is anxiety. Other concomitant presentations are pessimism, feelings of incapacity, a tendency to be sorry for oneself and to blame others for one’s problems. Depressive-anxiety also involves the development of other symptoms, including considerable difficulty in concentrating, the sensation of the mind being completely ‘empty’, sleep disorders and nightmares, the incapacity to keep still and excessive tiredness.
The clinical picture of presenting symptoms however may vary quite considerably on the basis of the prevailing of the anxious symptoms over depressive symptoms or vice versa. The question of comorbid depressive and anxious symptoms has been recently discussed in various quarters in order to clarify whether there are relations of causality between them, whether they represent different manifestations of a single disorder or whether they are totally independent. Various interpretations have been presented. In some cases it is admitted that the patient may have developed a depressive disorder following the presence of a series of anxious symptoms (e.g., Panic Disorder).
In other cases, authors refer to the comorbidity of two independent disorders (e.g., Major Depression and Panic Disorder). Very often the attempted clarification of such situations will be based on careful observation of the signs and symptoms involved and a reconstruction of their development over time. Occasionally, those suffering from a depressive-anxiety disorder may only present symptoms of anxiety in the first phase of the disorder, following which there will be a reduction in the intensity of the symptoms of anxiety and an increase in more typically depressive behaviour.
In a further group of cases, an episode of Major Depression may be associated (in the final phase) with numerous symptoms of anxiety, and, after remission of the depressive episode, there may be a residual anxiety disorder of varying intensity. Nowadays, and increasingly at the specialist level, there is a tendency to consider many clinical patterns of anxiety as manifestations of a depressive condition. It often occurs that anxious subjects undergo lengthy treatment with tranquilizers, however these are in fact depressed patients, who would quickly respond when specific therapy for depression is provided.
The following characteristics are typical of depressive-anxiety:
