How does the biological perspective explain OCD?

The most widely accepted neurobiological models of OCD rely on an increased cerebral metabolism in circuits involving the thalamus, OFC and the striatum—the CTSC model—which is thought to underlie behavioral alterations in multiple domains, including reward processing, action selection or habit-based functioning.

How do you assess a hoarding disorder?

Hoarding Rating Scale (HRS) The Hoarding Rating Scale is a brief 5-item scale that can be given as a semi-structured clinician interview or as a questionnaire. This tool includes 5 questions about clutter, difficulty discarding, excessive acquisition, and the resulting distress and impairment caused by hoarding.

Is OCD biological or psychological?

Thus, OCD is a biological disorder, rather than a “mental problem.” Interestingly, researchers bolstered the notion that the basal ganglia causes OCD when they linked the onset of OCD symptoms to several events, including: bacterial infections, hypoxia (lack of oxygen to the brain) and neurotoxic agents.

Is OCD biological or environmental?

OCD is a common debilitating condition affecting individuals from childhood through adult life. There is good evidence of genetic contribution to its etiology, but environmental risk factors also are likely to be involved. The condition probably has a complex pattern of inheritance.
