Tuberous sclerosis complex (TSC) is a genetic disorder characterized by the growth of benign tumors in multiple organs, most notably the brain, skin, kidneys, and heart. One of the most challenging aspects of TSC is the high prevalence of epilepsy, particularly infantile spasms and other seizure types that often develop early in life. Vigabatrin has become the treatment of choice for managing seizures associated with TSC, especially infantile spasms, due to its targeted and effective mechanism of action.

TSC-related seizures often begin in infancy and are typically difficult to control with conventional antiepileptic drugs. Vigabatrin, through its inhibition of GABA transaminase, elevates GABA levels in the brain, leading to a calming effect on neuronal excitability. This mechanism is particularly effective in the context of TSC, where brain lesions known as cortical tubers disrupt normal neural signaling and contribute to seizure activity.
Clinical studies have shown that vigabatrin is significantly more effective in stopping infantile spasms in children with TSC compared to other antiseizure medications. In many cases, early intervention with vigabatrin not only reduces or eliminates spasms but may also prevent the progression to other more severe forms of epilepsy. Furthermore, effective seizure control has been linked to improvements in developmental outcomes, which are often a concern in children with TSC.
While the benefits of vigabatrin in TSC are clear, its use still demands careful management. Visual field loss remains the most serious adverse effect associated with vigabatrin therapy. As such, patients with TSC on long-term vigabatrin treatment must be closely monitored through regular ophthalmologic evaluations, although assessing visual fields in very young or developmentally delayed children can be challenging.
TSC is a lifelong condition requiring comprehensive and multidisciplinary care. Neurologists, geneticists, ophthalmologists, and developmental specialists must collaborate to manage both seizures and the broader manifestations of the disorder. Vigabatrin, as part of this team-based approach, plays a central role in improving the quality of life for affected children and their families.
In summary, vigabatrin is a first-line treatment for managing seizures in patients with tuberous sclerosis complex, particularly when infantile spasms are present. Its unique action on GABA levels provides effective seizure control, which is critical for cognitive and developmental outcomes. Despite its risks, vigilant monitoring and coordinated care can ensure safe and successful treatment in this vulnerable population.
