[Ethnographic study of neurological and mental diseases among the Uru-Chipaya peoples of the Andean Altiplano].
BACKGROUND
The Uru-Chipaya people are an ethnic group of about 2,500 people, descendants of primitive Andean cultures. Their isolation (they live at an altitude of 4,000 metres in southern Bolivia), their non-written language (Chipaya-Puquina) and their traditional way of life, clothing and customs, which are similar to those used for thousands of years, make this an unusual culture. The aim of our work was to carry out an ethnographic study of the neurological diseases experienced by these people, the way they conceive such disorders and their therapeutic approaches to them.


METHODS
An ethnographic field study was conducted in June 2004. A structured interview was held with a yatiri, or Chipaya healer, to allow classification of the neurological or mental diseases. Epilepsy (tukuri) is interpreted as being a consequence of an evil spirit entering through the nose. Treatment consists in drinking an infusion containing dried powdered butterfly (jesko), birds or curupancho. Achamixi (headache) is common and is treated by drinking the yatiri's fermented urine, herb tea made from the chachacoma plant and by blowing, which is done by the yatiri over the patient's head. Fright, the symptoms of which are similar to those of a post-traumatic stress disorder, is treated by a wilancha, that is, the ritual sacrifice of a llama offered to the Pachamama. Sadness, the cultural equivalent to depression, is treated with infusions made from ayrampo, a plant found in the Andean Altiplano. Psychosis (sumsu), which is treated by means of a wilancha, and mental retardation/static encephalopathy (pustkis), which are considered to be a result of a fright suffered by the mother during pregnancy, also exist. No mention was made of the existence of extrapyramidal or vascular pathologies.


CONCLUSIONS
The cultural equivalents of certain neurological pathologies (headache, epilepsy, mental retardation, anxiety and depression) are present in this ancestral culture.
