Tuberous Sclerosis Complex (TSC) is a genetic condition that can cause a range of health issues, including epilepsy, learning difficulties, and autism. It is caused by changes in the TSC1 or TSC2 genes, which lead to problems in the mTOR pathway. This pathway is crucial for cell growth and survival. When it is not working properly, it can result in various health problems.

TSC can lead to severe epilepsy that starts early in life and is hard to control with medication. This, along with learning difficulties and autism, is often referred to as TSC-associated developmental and epileptic encephalopathy (DEE). The good news is that modern medicine has made it possible to identify babies at high risk for these issues before they even show symptoms. This is thanks to advances in prenatal testing and biomarker research.

Biomarkers are signs that can indicate the presence or risk of a disease. In the case of TSC, certain biomarkers can predict the likelihood of developing epilepsy and how a child's brain might develop. These include specific gene changes, unusual brain activity, and advanced brain imaging results. By identifying these biomarkers early, doctors can start interventions to prevent or reduce the severity of DEE.

One of the key strategies for prevention is starting treatment early. Medications like vigabatrin and mTOR inhibitors have shown promise in reducing the severity of epilepsy and improving outcomes. These drugs work by targeting the underlying mechanisms of the disease, rather than just treating the symptoms.

Beyond medication, there are other emerging strategies that offer hope for modifying the course of TSC. These include gene therapy, which aims to correct the genetic changes that cause the disease, and multi-omic profiling, which involves studying the genome, epigenome, transcriptome, proteome, and metabolome to understand the disease better. Environmental enrichment, such as providing a stimulating and supportive environment, can also play a role in improving outcomes.

The goal is to link these predictive biomarkers with effective, personalized interventions. This proactive approach can help prevent or mitigate the effects of TSC-associated DEE. By doing so, it advances clinical decision-making and moves towards a more precise and personalized form of prevention in pediatric epilepsy.

It is important to note that while these strategies offer hope, they are not a cure. More research is needed to fully understand and treat TSC. However, the progress made so far is a significant step forward in improving the lives of children with this condition.
