Perseverations miasms

Clinic

Perseveration is the repetition of a particular response (such as a word, phrase, or gesture) regardless of the absence or cessation of a stimulus.

• Lacking ability to transition or switch ideas appropriately with the social context, as evidenced by the repetition of words or gestures after they have ceased to be socially relevant or appropriate", or the "act or task of doing so", and are not better described as stereotypy

• Perseveration is also sometimes seen as a symptom of aphasia.

Etiology

• Traumatic brain injury esp in frontal lobe lesions (Lateral orbitofrontal cortex or inferior prefrontal convexity (Brodmann areas 47/12)) are affected.
• Frontal lobe syndrome, as well as neurodegenerative diseases such as progressive supranuclear palsy, corticobasal syndrome and chronic acetogenin poisoning.
• Perseveration may also refer to the obsessive and highly selective interests of individuals on the autism spectrum.
• In ADHD, perseveration or "hyperfocus" commonly occurs  as an impairment of set shifting and task switching.
• In people who are both intellectually gifted and have a learning disability, the state of hyperfocus and flow can be confounded with perseveration.
• Apart from their direct symptoms, OCD can have specific problems with set shifting and inhibition of prepotent responses.
