Overview

Medical therapy is generally preferred over surgical ones due to their fewer number of complications and diminishing side effects over time.

Medical Therapy

Epilepsy

  • Anti-seizure medications can be prescribed to control seizures. The preferred medication is vigabatrin[1], but other anticonvulsants, clobazam, ketogenic diet, or surgical procedures.[2] Treatment before the onset of epilepsy and other neuropsychiatric manifestations may be beneficial, but trials testing this approach are still ongoing (EPISTOP trial). mTOR inhibitors may present with some anti-epileptogenic properties.[2]

Lymphangioleiomyomatosis

Angiomyolipoma

  • Treatment is done in a pre-emptive manner to prevent bleeding, reduce tumor size or slow its growth. Systemic everolimus is the preferred method nowadays but there are also surgical options. [2]

Subependymal Giant Cell Astrocytoma

  • Treatment with mTOR inhibitors have been recommended, being well tolerated and presenting with side effects that decreases over time.[2] There are also surgical procedures but they have important complications.

Tuberous Sclerosis Complex-associated Neuropsychiatric Disorder

  • There are no specific interventions, patients must be followed closely by a psychiatrist. Trials exploring the use of mTOR inhibitors for this manifestation are ongoing.[2]

Skin Lesions

For TSC-associated skin lesions, the following treatments may be performed:

  • Sun protection;
  • "Camouflage make-up"
  • Topical mTOR inhibitors.
  • There are surgical options and ablation.

mTOR Inhibitors side effect:

mTOR inhibition therapy may cause stomatitis, diabetes, hyperlipidemia, wound-healing complications, infertility and delayed sexual maturation.[2]
