A psychogeriatric assessment program. IV. Interdisciplinary aspects

The interdisciplinary aspects of the psychogeriatric assessments described in three previous papers are discussed on the basis of factor-analysis findings and their significance in diagnosis, treatment, planning and theory. The difference between basic biopsychologic dysfunctions (including pathohistologic changes and various counter-regulations) and psychosocial dysfunctions (lifestyle) becomes clear statistically as well as clinically. This difference probably is fundamental, in the sense that intact biopsychologic functions are elementary tools for the psychosocial functions.
