Abstract
As mood disorders constitute a major public health interest, many of the works that have been done in our “Department Of Psychiatry” were interested in discussing and studying mood disorders from many different aspects.
And as any research or review should not be an end point, but it must open the door for new researches and studies and their conclusion must direct our clinical practice.
That’s why we must have a research strategy. Aiming from time to time to revise the works done, trying to make use of their efforts and detecting what we are missing in these areas, looking at the end for a complementary work system.
This review was designed as a first step to illuminate this idea, by trying to throw a light on the major works done in the field of mood disorders over the past 20 years.
We can observe that medical literatures are vast and rapidly expanding. And the concept of evidence- based medicine has acquired increasing importance during the last decade, its simply the integration of individual clinical experience and best available external evidence from systematic researches in making decisions about patient’s care.
This raises the need for every psychiatrist to have the ability of “critically appraising” works to decide the validity of the scientific papers and reviews and how they could be applicable in our practice.
That’s why we intended in this work not only to summarize the work done, but also to represent the basic concept of how the reviews and researches could be critically reviewed.
