The patient presented truncal ataxia, tremor in both hands that could be increased voluntarily, dysarthria, and bilateral dysmetria finger-to-nose test. Intermittent light stimulation generated a photoparoxysmal response at low frequencies. During the following months, he presented several generalised tonic-clonic seizures.
Results from the lysosomal enzyme study were also unremarkable. Given the lack of response to medication, doctors added phenobarbital 90 mg per day and ethosuximide mg per day to reduce generalised seizures and absence seizures, respectively.
