Neuropsychiatric problems in tuberous sclerosis complex.

Abstract

Tuberous sclerosis complex is an autosomal dominant disorder characterized by abnormal cellular differentiation and proliferation, as well as abnormal neuronal migration. It is a disease affecting multiple organ systems and typically has brain involvement, causing severe disabilities. This article reviews the literature of the commonly associated neuropsychiatric complications, including mental retardation, autism-like features, and other behavior problems, which are discussed in the context of the neuropathology and epilepsy observed in tuberous sclerosis complex. The potential pathogenesis of neuropsychiatric problems is explored, including links to the genetics, neuropathology, neurotrophins, and epilepsy factors associated with tuberous sclerosis complex. Treatment of neuropsychiatric symptoms, including autism-like features, attention deficits, and sleep disorders, is also discussed.
