[Convulsive syndrome in infectious-toxic lesions of the brain in children].

A clinico-electroencephalographic study covered 64 children aged 1 month to 5 years who presented the encephalitic syndrome, encephalitis and meningoencephalitis due to respiratory and enteroviral infection. Age-specific characteristics of the paroxysmal syndrome are described in detail. It has been shown that an important role in the genesis of the development of paroxysmal attacks in young children is played by a low threshold of convulsive readiness and by an unfavourable premorbid background. Children under 5 years of age presented no epileptic foci on the EEG in the course of the encephalitic syndrome, encephalitis and meningoencephalitis.
