Comorbidity of severe mental disorders and physical illness: issues arising Comorbidity of mental and physical illness is a major, perhaps main problem facing medicine in the years before us. In addition to shortening the life expectancy of people with mental illness comorbidity with physical illness comorbidity significantly and negatively affects the quality of life of the people who experience the mental and physical illnesses and their carers and increases the cost of health care. What makes the problem even more and challenging is that medicine is currently in the process of fragmentation into ever more narrow specialties which adds difficulty in the provision of care, Most of the solutions which have been proposed – collaborative care, in-service education of general practitioners and others did not turn out to be effective solutions in dealing with the problems of comorbidity. A significant revision of undergraduate and postgraduate training in medicine is most probably an essential component of the answer to the challenge of this type of comorbidity which will also require a reorganization of health services and their financing.

Stress-related disorders are diverse and they may be mental and physical. Often, several body systems and organs are involved simultaneously. The pathophysiology of stress-related disorders involves many factors: an observable or perceived stressor, an individual dynamically evolving vulnerability and maladaptation leading to imbalance, as well as environmental, cultural, gender and life-cycle variables. There is a need to develop a comprehensive quantifiable stress assessment instrument. It would be based on the ‘stress factor’, a dimension that would integrate biological, psychological, social, economic and spiritual parameters and would allow for cultural sensitivity. It would contribute to clinical operational sophistication and would illuminate treatment options and multidimensional well-being interventions. Hopefully, it would facilitate development of culturally sensitive pharmaceutical or biophysiological adaptogens and homeostatic interventions.
