Delirium (i.e., acute confusional state) is a frequent syndrome due to different exogenous (physical, chemical or biological) factors. The prevalence of delirium increases with higher age (e.g., signs indicative of dementia) and particularly in those patients with severe somatic illness. ⋯ The article summarizes data on symptomatology, aetiology and pathogenesis of delirium. In addition syndromes sharing phenomenology similar with delirium are discussed and treatment recommended.
