New Dimensions in the OCD Spectrum: Autism, Pathologic Gambling, and Compulsive Buying

The obsessive-compulsive spectrum can be divided into two subclusters: disorders of impulsivity and neurologic disorders (Figure 1). This article examines autism (from the neurologic cluster) and pathologic gambling and compulsive shopping (from the impulse side of the spectrum). These three disorders are major mental health problems, impacting on society, the affected individuals, and their families. In addition, these three disorders are underrecognized and underdiagnosed. In this article, we outline and review the phenomenology, psychopathology, and treatment options of these three disorders.
