ICD-10 and DSM-IV differ in their definitions of delirium. The DSM-IV definition centers around a disorder of attention and cognitive functions, whereas ICD-10 describes delirium as a broader neuropsychological and psychopathological syndrome, e.g. hallucinations, emotional and psychomotor disorder.
When neuropsychological and psychopathological symptoms of delirium are assessed simultaneously, our question was, if there are core symptoms of delirium, i.e. neuropsychological and psychopathological symptoms. The approach is to identify core symptoms of delirium 1. by a high interrelation, 2. and furthermore core symptoms of delirium should show this interrelation consistently across different etiological groups of delirium.
There are consistent correlations between psychopathological symptoms of delirium and neuropsychological findings of cognitive deficits. These consistent correlations seem to be largely restricted to the domain of the disorder of awareness and reagibility and are not found in a systematic way for symptoms in the fields of associated features of delirium like emotional, vegetative or circadiane disorders.
