Smell and taste acuity in epileptic syndromes

Taste and smell acuity were determined in 50 normal subjects and 48 epileptic patients by means of Henkin's method. Smell detection thresholds are greatly reduced in epileptic patients, mainly those suffering from partial seizures with complex symptomatology. Epileptic patients show also a reduced threshold for sweet and bitter taste. Age, sex and antiepileptic drugs do not affect taste and smell acuity. The significance of these findings in the pathogenesis of epileptic seizures is discussed.
