Benedikt syndrome with cerebellar-outflow syndrome

Epileptic encephalopathy with continuous spike-and-wave during sleep

Epilepsy with continuous spike-and-waves during sleep syndrome can be characterized by the following features: (1) epilepsy, with focal and apparently generalized seizures; (2) neuropsychological impairment with global or selective regression of cognitive functions; (3) transient motor impairment with ataxia, dyspraxia, dystonia, or unilateral deficits; (4) typical EEG findings with diffuse or more or less unilateral electrical status epilepticus during slow sleep occurring in up to 85% of slow sleep.
