Congenital bilateral perisylvian syndrome

Congenital Bilateral Perisylvian Syndrome (CBPS) is a rare neurological disorder that primarily affects the cerebral cortex, the part of the brain responsible for higher level cognitive functions. The syndrome is characterized by partial paralysis (Paresis) of the muscles on both sides of the body, intellectual disability, and difficulties with speech and swallowing.

Etiology

The exact cause of CBPS is unknown. However, it is believed to be associated with malformations in the perisylvian region of the brain, which is involved in language and speech production. Some researchers suggest that these malformations may occur during the early stages of fetal development, possibly due to genetic mutations or environmental factors.

Symptoms

The most common symptoms of CBPS include dysarthria (difficulty articulating words), dysphagia (difficulty swallowing), and oromotor dysfunction (difficulty controlling the muscles of the mouth and throat). Some individuals may also experience seizures, intellectual disability, and/or developmental delays.

Diagnosis

Diagnosis of CBPS is typically based on a combination of clinical examination and imaging studies, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. These imaging studies can reveal characteristic abnormalities in the perisylvian region of the brain.

Treatment

There is currently no cure for CBPS. Treatment is symptomatic and supportive, and may include physical therapy, speech therapy, and medications to control seizures.

Prognosis

The prognosis for individuals with CBPS varies widely, depending on the severity of symptoms and the individual's response to treatment. Some individuals may lead relatively normal lives with appropriate support and treatment, while others may require lifelong care.
