Neuroimaging and genetic syndromes
Neuroimaging technology has leapt forward in the past 20 years. Neuroimaging techniques have had a dramatic impact in psychiatry research, and this impact is clearly demonstrated in the ®eld of intellectual disability (ID). In addition, it has become signi®cantly more available as a clinical tool, such that both magnetic resonance imaging (MRI) and computerised tomography (CT) have become a regular and usual part of clinical mental health practice. This chapter reviews currently available neuroimaging techniques, illustrates their research applications in representative neurodevelopmental disorders associated with ID, and considers the role of neuroimaging and genetic screening in the Behavioural Genetics Clinic at the Maudsley Hospital ± a specialist clinic for adults who may have neurodevelopmental disorders.
