Answer

Use a Wood lamp to examine the skin. Tuberous sclerosis is the single most common recognizable cause of infantile spasms. Therefore, a careful examination of the skin for the characteristic hypopigmented lesions of tuberous sclerosis is mandatory. The unaided bedside identification of these lesions may be more difficult in patients with a light complexion.
