basal ganglia

• The basal ganglia is involved in motor control and the formation of habitual behaviours. .
• In individuals with OCD, the basal ganglia is thought to be overactive or dysfunctional, leading to difficulties in suppressing repetitive thoughts and behaviours.
• This overactivity may contribute to the persistent compulsions seen in OCD, such as excessive handwashing.
• Additionally, the basal ganglia’s connection to the caudate nucleus, which is responsible for filtering and regulating thought patterns, can result in an amplified feedback loop, making it harder for individuals to disengage from intrusive thoughts or compulsive actions
