Final answer:
Obsessive Compulsive Spectrum Disorder encompasses a range of disorders with similar characteristics to OCD, including repetitive behaviors and persistent thoughts. There's a genetic basis to these disorders, and treatments focus on improving quality of life for affected individuals.
Step-by-step explanation:
The term 'Obsessive Compulsive Spectrum Disorder' refers to a range of disorders that share core features of obsessive-compulsive disorder (OCD), which include repetitive behaviors and intrusive, persistent thoughts. Research indicates that there is a genetic contribution to OCD, as studies have found heritability factors in these conditions.
Notably, functional neuroimaging studies, such as those by Saxena et al. and Rotge et al., have identified fronto-striato-limbic hyperactivation in individuals with OCD during symptom provocation. Quality of life is often significantly impaired in those suffering from OCD, as symptoms can lead to difficulties in social interaction and daily functioning.
Understanding the underpinnings of OCD is complex, involving a mix of genetic, neurobiological, and environmental factors. Investigations into the neurobiology of OCD by researchers like Graybiel and Rauch emphasize the intricate circuitry thought to be involved in the pathophysiology of OCD. Overall, treatments are aimed at reducing symptom severity and improving quality of life for individuals affected by OCD and related disorders.
