Differential diagnosis of cataplexy and generalized epilepsy. Case report

Cataplexy is rare disease, the main clinical features of which are loss of muscle tone without loss of consciousness, associated with specific factors such as laughter, and less often fear, anger or crying. The differential diagnosis of epileptic seizures and cataplexy is often difficult because of similar clinical features. Establishing the diagnosis of cataplexy is important because in most cases it is associated with narcolepsy; in addition, misinterpretation of cataplexy can lead to hyperdiagnosis of epilepsy or wrong efficiency mark of antiepileptic drugs. Clinical and instrumental examination is necessary to establish the right diagnosis. Literature review and own clinical case is described.
