Many so-called psychotics are likely to become incapacitated at one moment or another of their lives. This condition, which provokes immense human suffering, may lead to permanent reclusion in mental hospitals and at worst may induce criminal acts. Psychosis is a symptomatology in which the individual fails to discriminate between stimuli and information received from the external world and stimuli arising within himself. An imaginary process of reorganization of the world becomes the sole way to deal with conflict, accentuating the incapacity for corrective learning. This condition generates disorders of perception, of thinking, of consciousness, of affectivity and mood and of activity. Psychoses are of two types, based on the underlying physical disease: organic psychoses including brain tumours, senile dementia, and general panesis; and functional psychoses including schizophrenia, manic-depressive psychosis, and affective psychosis.
Psychosis accounts for 5 to 15% of the total admissions to mental hospitals; approximately half of these are people diagnosed as suffering from schizophrenia, the major so-called functional psychosis. The majority of the remaining cases are due to a variety of organic psychoses, predominantly aged people suffering from senile or arteriosclerotic psychoses.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
