How might succinic semialdehyde dehydrogenase deficiency be treated?

Treatment of succinic semialdehyde dehydrogenase deficiency (SSADH) is generally symptomatic and typically focuses on the treatment of seizures and neurobehavioral disturbances. Antiepileptic drugs (AEDs) that have proven to be effective in treating the seizures associated with this condition include carbamazepine and lamotrigine (LTG). Medications such as methylphenidate, thioridazine, risperidal, fluoxetine, and benzodiazepines appear to be effective at treating anxiety, aggressiveness, inattention, and hallucinations. Additional treatments may include physical and occupational therapy, sensory integration, and/or speech therapy.[1]
