Prognosis and Duration of disabling effects
The average length of a depressive episode is about 6 months but about 25% of people have episodes lasting more than a year and about 10-20% develop a chronic unremitting course.
It is not possible to specify with accuracy the duration of any individual depressive episode, as people with severe disability usually respond well to treatment.
For infrequent repeated episodes it would be reasonable to award for a limited period initially whilst awaiting the outcome of response to treatment.
In the great majority of cases any evident care needs will only be for a limited period, which is unlikely to exceed several months during any one episode.
There is evidence that the prognosis is worse in older people.
Criteria that indicate chronicity in depressive Illness
The following are associated with an increased likelihood that depression will be chronic:
- Increased severity
- Longer duration
- Older age (especially over 60)
