Rasmussen syndrome

Rasmussen Syndrome is a rare, progressive, chronic encephalitis (inflammation of the brain) that typically affects only one hemisphere of the brain. It is most commonly seen in children under the age of 10, although adolescents and adults can also be affected.

Symptoms

The initial symptoms of Rasmussen Syndrome may include seizures, hemiparesis (weakness on one side of the body), and hemianopsia (loss of vision in one half of the visual field). As the disease progresses, it can lead to severe cognitive and physical impairments, including mental retardation and paralysis.

Causes

The exact cause of Rasmussen Syndrome is unknown. Some researchers believe it may be an autoimmune disease, while others suggest it could be caused by a viral infection.

Diagnosis

Rasmussen Syndrome is typically diagnosed based on the clinical symptoms, neuroimaging findings, and the progression of the disease. A brain biopsy may also be performed to confirm the diagnosis.

Treatment

There is currently no cure for Rasmussen Syndrome. Treatment is aimed at managing the symptoms and may include antiepileptic drugs to control seizures, physical therapy to manage hemiparesis, and corticosteroids to reduce inflammation. In severe cases, a surgical procedure called hemispherectomy may be performed to remove or disconnect the affected side of the brain.

Prognosis

The prognosis for individuals with Rasmussen Syndrome varies. Some individuals may have a relatively mild course of the disease, while others may experience severe cognitive and physical impairments.
