Modern psychiatry must take into account more and more the so called cultural differences in its practice. These differences are not merely the evident cultural aspects of diverse ethnic origin, but also the differences determined by economic, social and cultural reasons.

The main paradox of our times is that we try to believe on the ilusion of people homogenicity consequent to the globalization process, when we see that everyone access to the same markets, products, services and news or when we see that everyone can communicate with everyone all over the world. This ilusion is reinforced by the higher cosmopolitism levels of our towns, where we can see people from different ethnic or cultural backgrounds sharing the same space in a reasonable harmonic way.

However, this ilusion is covering the intimate aspiration of any person or group to preserve his identity and afirm his own values. In fact we are living in a society that expresses multiethnic, multiculture and multisocial differences in an interdepedent diversity.

Hospitals are in a way microsocieties where this paradox emerge or in purely sociologic terms described above, but also by the clinical expression of this diversity.

CL-Psychiatry is the field where this subject must be known and researched. This presentation will reviewed the situation.
