Abstract

Amanita muscaria contains more excitatory ibotenic acid and less depressant muscimol compared to Amanita pantherina. In this study A. muscaria poisoned patients were more often confused (26/32, p = 0.01) and agitated (20/32, p = 0.03) compared to those poisoned with A. pantherina (8/17 and 5/17). Patients poisoned with A. pantherina were more commonly comatose (5/17) compared to those poisoned with A. muscaria (2/32) (p = 0.03). In conclusion, the so-called ibotenic or pantherina-muscaria syndrome might be divided into two subtypes.
