A very rare nerve disorder characterized by weakness or paralysis of face, jaw tongue and throat muscles. Other symptoms include seizures, delayed development and mental retardation. See also Perisylvian syndrome

Perisylvian syndrome is a rare neurological disorder that is also known as congenital bilateral perisylvian syndrome or CBPS. It is a developmental disorder that affects the brain and is typically present at birth.

Perisylvian syndrome is characterized by a wide range of symptoms, which can vary from person to person. The most common symptoms include difficulties with speech and language, such as problems with articulation, grammar, and vocabulary. Many people with perisylvian syndrome also have seizures, which may be difficult to control with medication. Other symptoms may include difficulties with fine motor skills, weakness on one side of the body, and intellectual disability.

Perisylvian syndrome is caused by abnormal brain development in the perisylvian region of the brain, which is located in the area surrounding the Sylvian fissure. This region of the brain is important for language processing, and abnormalities in this area can lead to the speech and language problems associated with perisylvian syndrome.

There is no cure for perisylvian syndrome, and treatment is usually focused on managing the symptoms. This may involve speech therapy to help improve communication skills, as well as medication to control seizures. Physical and occupational therapy may also be helpful for improving fine motor skills and overall physical function. The long-term outlook for people with perisylvian syndrome varies depending on the severity of their symptoms, but many people are able to live relatively independent lives with appropriate support and care.
