Tuberous sclerosis complex (TSC): neurological features

Written and reviewed by Dr Ibrahim Imam, Consultant Neurologist. Last reviewed .

Tuberous sclerosis complex (TSC): neurological features. Seizures occur in >60% of cases. They are early and severe. Fully referenced neurology checklist.

Seizure features

  • Seizures occur in >60% of cases
  • They are early and severe
  • They are usually focal seizures or infantile spasms
  • Infantile spasms are more frequently seen with TSC1
  • Diffusion tensor imaging (DTI) may identify epileptogenic tubers
