The Tuberous Sclerosis Alliance is offering new resources about tuberous sclerosis complex (TSC)-Associated Neuropsychiatric Disorders (TAND) on its website at http://www.tsalliance.org/TAND. These new resources include a video presentation by Petrus J. de Vries, MBChB, MRCPsych, PhD, and links to two recent medical journal articles about TAND. The TAND Checklist, described in the video, was developed to help clinical teams, individuals with TSC, and their families screen for TAND at every clinic visit and prioritize what to do next. TAND is a new terminology to describe the interrelated functional and clinical manifestations of brain dysfunction in TSC, including aggressive behaviors, autism spectrum disorders, intellectual disabilities, psychiatric disorders, neuropsychological deficits, and school or occupational difficulties. These manifestations are often of great concern to individuals with TSC and their families.
