Tuberous sclerosis is a rare genetic disease that causes benign tumors to grow in the brain and other organs. Symptoms vary, depending on where the tumors grow. They could include
Skin problems, such as light patches and thickened skin
Seizures
Behavior problems
Intellectual disabilities
Kidney problems
Some people have signs of tuberous sclerosis at birth. In others it can take time for the symptoms to develop. The disease can be mild, or it can cause severe disabilities. In rare cases, tumors in vital organs or other symptoms can be life-threatening.
Tuberous sclerosis has no cure, but treatments can help symptoms. Options include medicines, educational and occupational therapy, surgery, or surgery to treat specific complications.
