The Tuberous Sclerosis Complex 1998 Consensus Conference clinical criteria
represent an important advance in the diagnosis of tuberous sclerosis compl
ex. Since many findings regarded as highly specific for tuberous sclerosis
complex are not apparent until late childhood or adulthood, refinements by
age may prove of value. We have stratified 106 children into five age group
s (0 to 2 years of age, above 2 to 5 years, above 5 to 9 years, above 9 to
14 years, and above 14 to 18 years). Physicians should be alerted as to the
frequency of the criteria in different stages of children.
