One hemisphere (half) of the brain experiences persistently worsening inflammation (encephalitis) in Rasmussen's encephalitis (RE), an extremely uncommon illness. It is also known as Rasmussen syndrome. This inflammation causes progressive and irreversible brain damage as well as frequent convulsions (epilepsy). As a result, the impacted hemisphere of the brain stops functioning. As the inflammation worsens, one side of your body becomes weaker and your mental health deteriorates. The doctor who initially identified the disease in 1958, Theodore Rasmussen, is honored by the condition's name.
Early detection and treatment can prevent additional neurological damage, minimize cognitive decline, and possibly stop the disease's course. Prompt treatment of Rasmussen's encephalitis is essential for improving a patient's long-term result.
You must watch for symptoms of Rasmussen’s Encephalitis in children. A typical early symptom is mild weakness in your child's arm or leg.
Seizures typically become more frequent. With epilepsia partialis continuous (EPC), which occurs when seizures occur every few seconds or minutes, approximately half of patients with Rasmussen's encephalitis have this condition. Additionally, the seizures are intractable, meaning that medication cannot totally stop them.
These symptoms usually appear a few months to a few years after the initial seizure:
Signs and symptoms are
Causes
Although the exact etiology of Rasmussen's encephalitis is unknown, scientists have two theories:
Autoimmune disease: When your immune system targets healthy tissue for unclear reasons, you have an autoimmune disease. Rasmussen's encephalitis may be an autoimmune disease that affects one side of the brain, according to researchers.
Infection: An unidentified virus may infect your brain and cause Rasmussen's encephalitis. Nevertheless, despite thorough examinations of the afflicted brains, scientists have not been able to pinpoint a particular virus.
Risk Factors
Age a compromised immune system, viral exposure, and environmental variables are risk factors for encephalitis.
Complications
Additional issues include permanent brain damage, speech and language issues, and loss of movement skills.
Rasmussen's encephalitis is currently treated in India mainly with anti-seizure drugs, immunotherapy with intravenous immunoglobulin (IVIG) or corticosteroids in the early stages, and the possibility of surgery, such as a functional hemispherectomy, for severe, refractory cases where the affected brain hemisphere is severely compromised. These cases frequently require consultation at specialized epilepsy centres, but access to more advanced treatments, such as newer immunomodulatory therapies, may differ based on availability and location.
You cannot prevent Rasmussen's encephalitis because it is extremely uncommon and the reason is unknown to researchers.
Immunotherapy: Frequently used drugs for immunotherapy are:
Corticosteroids: Because of its strong anti-inflammatory effects, high-dose methylprednisolone is frequently used in the early stages, but prolonged use can have serious adverse consequences.
Cost Start From USD 3000 - USD 5000Explore Options
Intravenous immunoglobulin (IVIG): Often regarded as a cornerstone therapy, IVIG has the ability to alter the immune system and possibly lower inflammation.
Brain surgery: The best way to treat seizures in RE is with a hemispherectomy. Half of your child's brain must be surgically removed or disconnected from the remainder of their brain. The impacted hemisphere's function has already been lost in the majority of infants who have this operation. Following surgery, there is very little chance of future function loss. When the advantages of surgery exceed the risks, providers always take it into consideration.
Rasmussen's encephalitis is diagnosed by medical professionals based on your child's symptoms and certain test findings:

Here are some of the reasons for choosing India:
Rasmussen's encephalitis has no known treatment. Rather, the aim of treatment is to control inflammation and symptoms. Treatment options could consist of: Drugs that prevent seizures: Anti-seizure drugs typically don't fully control seizures brought on by RE.
The nation's healthcare institutions offer top-notch treatment alternatives, guaranteeing successful outcomes for many patients. Anti-seizure drugs, immunotherapy with intravenous immunoglobulin (IVIG) or corticosteroids in the early stages, and surgical intervention such as a functional hemispherectomy for severe, refractory cases are the mainstays of the most recent treatment for Rasmussen's encephalitis in India.
Yes, many Indian hospitals offer the following for Rasmussen’s Encephalitis treatment:
Always consider the following factors when selecting Indian hospitals:
In general, Rasmussen’s Encephalitis treatment has much improved in India. Controlling inflammation and symptoms is the aim of treatment. Among the treatments are anti-seizure drugs and immunosuppression therapy. In some cases surgery is suggested.
Only a doctor can diagnose Rasmussen’s Encephalitis through various tests and diagnoses. Brain MRIs are now a standard procedure for diagnosing and monitoring Rasmussen's encephalitis. Most individuals often have unilateral ventricular system hypertrophy within months of the acute stage beginning.
Rasmussen's encephalitis causes chronic inflammation of the brain, which can lead to permanent brain damage, loss of motor skills, and mental impairment. With an estimated 200–500 instances worldwide, the illness is extremely uncommon and usually affects youngsters between the ages of 2 and 10.
Providing a supportive environment, managing symptoms with medication and therapies as directed by the doctor, closely monitoring the child's seizures, seeking specialized care such as physical, occupational, and speech therapy, and being ready for any necessary surgical procedures, such as a hemispherectomy, are all part of caring for a child with Rasmussen's Encephalitis. Always check with your child's medical team for the best course of action.
