#reactive psychosis

• Abeche - An eponym used in transcultural psychiatry, clinical epidemiology, and medical anthropology, associated with the Abéché region in Chad (the Abeche syndrome or nodule). In neuro-epidemiology textbooks, the term is historically linked to African outbreaks of cerebrospinal meningitis or visceral parasites that produce behavioral alterations, severe confusional states, and reactive psychotic episodes, serving as a model for studying correlations between tropical infectious diseases and secondary somatopsychic manifestations.
