Somatoparaphrenia is a type of monothematic delusion where one denies ownership of a limb or an entire side of one's body. Even if provided with undeniable proof that the limb belongs to and is connected to their body, the patient produces elaborate confabulations about whose it is or how it got there.

Causes

Somatoparaphrenia is most commonly observed after a stroke, affecting the right parietal lobe of the brain. This condition is also associated with other neurological disorders such as Alzheimer's disease and migraines.

Symptoms

The primary symptom of somatoparaphrenia is the denial of ownership of a limb or an entire side of the body. The patient may also experience hallucinations, confabulation, and sometimes neglect of the affected limb.

Diagnosis

Diagnosis of somatoparaphrenia is primarily based on the patient's symptoms and medical history. Neurological examinations and brain imaging techniques such as MRI and CT scan may also be used to confirm the diagnosis.

Treatment

Treatment for somatoparaphrenia primarily involves neuropsychological rehabilitation. This includes therapies such as mirror therapy, cognitive behavioral therapy (CBT), and physiotherapy. Medications may also be used to manage symptoms.
