This is a lower-risk surgery than a resection, with a faster recovery time, but this is not a viable treatment for everyone living with TSC and seizures. Tuberous sclerosis complex is an autosomal dominant disorder of cellular proliferation and differentiation due to mutations in TSC1 or TSC2. If left untreated, it can result in a delay of developmental milestones, the loss of previously acquired skills, and permanent intellectual disability. A study published in the medical journal Pediatrics earlier this year found that 39 percent of TSC patients reported missed symptoms or signs of TSC that should have led to an earlier diagnosis.

Bringing a magnet to the implant causes it to produce a pulse of electricity, which can stop or reduce the severity of an oncoming seizure. Tuberous sclerosis is a lifelong condition that requires careful monitoring and follow-up because many signs and symptoms may take years to develop. A seizure is the uncontrolled electrical activity in the brain, which may produce a physical convulsion, minor physical signs, thought disturbances, or a combination of symptoms.
