Current research indicates that almost all sicknesses have psychological causes along with their physical ones. Therefore psychological treatment of many sicknesses is in practice in many developed countries, along with or without medication. This is not just for mental disorders, and very serious sicknesses like Chronic heart Disease (CHD) , cancer have incorporated psychological treatment to its standard treatment regime as a vital component. In Sri Lanka there are only very few registered psychologists & there are none in the government medical service.
