[Tuberous sclerosis complex: diagnosis and current treatment]

Tuberous sclerosis complex is an autosomal dominant genetic multisystemic disorder caused primarily by mutations in one of the two tumor suppressor genes TSC1 or TSC2, resulting in increased activation of the mTOR pathway. Regarding clinical manifestations, a wide range of phenotypic variability exists, with symptoms constellations that may differ in affected organs (brain, skin, heart, eyes, kidneys, lungs), age of presentation and severity, but usually with great impact in biopsychosocial aspects of health and in quality of life. Main clinical neurological features are epilepsy (frequently, antiepileptic drug-resistant epilepsy), neuropsychiatric disorders, and subependymal giant cell astrocytomas. Recently, many therapeutic strategies have developed, including preventive treatment of epilepsy, new options for treatment of epilepsy as cannabidiol, mTOR inhibitors, ketogenic diet, and a more precise epilepsy surgery. Subependymal giant cell astrocytomas may require surgical procedures or mTOR inhibitors treatment. mTOR inhibitors may also be useful for other comorbidities. To improve quality of life of patients with tuberous sclerosis complex, it is essential to be able to deliver an integrated approach by specialized multidisciplinary teams, coordinated with primary care physicians and health professionals, that include access to treatments, attention of psychosocial aspects, and an adequate health care transition from pediatric to adult care.
