Encephalitis Treatment: Medicines, Diet & Management

How is Encephalitis Treated Based on Severity?

The treatment approach for encephalitis varies with the severity of symptoms and the level of medical support required. Here is an overview of the treatment options based on severity:

Clinical Severity	Treatment Approach
Mild	Bed rest, sufficient fluid intake and anti-inflammatory medicines to relieve headaches and fever. Antiviral medicines may be used for treating underlying infections.
Moderate	Hospitalisation may be required for closer monitoring, oxygen therapy and intravenous antiviral medicines or fluids.
Severe	Care in a neurology ICU may be needed, with mechanical ventilation, management of raised intracranial pressure and continuous EEG monitoring.

Types of Encephalitis and Their Treatment

Encephalitis may be autoimmune or caused by an infection. Let us understand how these types are treated:

Type of Encephalitis	Treatment Approach
Autoimmune Encephalitis	Immunomodulatory treatments such as corticosteroids, IV immunoglobulin and plasma exchange. Long-term immunosuppressive medicines are needed in some cases.
Infective Encephalitis	Antiviral medicines (oral or IV) to treat the underlying infection. Supportive care may include breathing assistance, intravenous fluids for dehydration, anti-inflammatory medicines and anti-seizure medicines.

Oral Medicines for Encephalitis

The medicines used for treating encephalitis depend on its underlying cause and the patient's condition. The following are commonly prescribed medicines:

Antiviral Medicines: These medicines are prescribed when encephalitis is caused by a viral infection. Acyclovir, ganciclovir, foscarnet and ribavirin may be used depending on the specific virus and clinical situation.
Antibiotics: Antibiotics are recommended when bacterial infections are responsible for encephalitis. Medicines such as ceftriaxone, penicillin G and vancomycin can be prescribed as appropriate.
Steroids: In some cases, steroids are used as an additional treatment for certain types of encephalitis, including autoimmune encephalitis and some infectious causes. They help reduce inflammation and swelling in the brain and may help lower intracranial pressure.

Other Treatments for Encephalitis

Apart from medicines, the following treatments may be recommended for encephalitis depending on the type and severity of the condition:

Immunomodulatory Therapy For autoimmune or post-infectious encephalitis, immunotherapy may be used under specialist guidance. Treatment options include corticosteroids, intravenous immunoglobulin (IVIG) and plasma exchange (plasmapheresis). These therapies help reduce excessive immune system activity and control inflammation.
Supportive Care Severe encephalitis may require intensive supportive care to stabilise the patient and manage symptoms. This may include enteral nutrition through tube feeding when the patient is unconscious or unable to eat, breathing assistance and monitoring of breathing and heart function. Anticonvulsant medicines may be used to control seizures, while intravenous fluids can maintain hydration and appropriate measures can help manage fever.
Rehabilitation and Long-Term Care Some patients may experience lasting neurological effects after the acute phase of encephalitis. Rehabilitation may include physiotherapy, occupational therapy and speech therapy to support recovery, improve cognitive and motor function and enhance quality of life.

Note: The above listed treatment for encephalitis must be taken as per the advice of qualified medical professionals.

Ayurvedic and Alternative Treatments for Encephalitis

The complementary therapies given below may support recovery from encephalitis:

Ayurvedic Therapies: External therapies such as Udwarthanam, Nadi Sweda, Nasya and Shirodhara may be used during recovery to improve mood, help with relaxation, and stabilise your neurological system.
Acupuncture: Acupuncture may help support relaxation, reduce inflammation and improve overall functioning during recovery.
Yoga: Gentle asanas (physical poses) like Savasana (Corpse Pose), Balasana (Child’s Pose), and Bhujangasana (Cobra Pose) support circulation and help build muscle strength. Pranayama (breathing exercises) may encourage relaxation.

Note: Alternative treatments for encephalitis should be used only under the guidance of qualified heathcare providers.

Home Care for Managing Encephalitis

While dealing with encephalitis, the following home care measures can help in a smoother and faster recovery:

Take adequate bed rest and avoid strenuous activities while recovering.
Drink plenty of healthy liquids to reduce the chances of dehydration, which may require hospitalisation if severe.
Take all prescribed medicines on time and follow your doctor's instructions carefully.
With your doctor's advice, take medicines to manage fever and other symptoms, and do not ignore any worsening or persistent symptoms.
Monitor your blood pressure regularly if advised by your doctor.
If you are struggling with your mental health during recovery, consider options such as therapy, meditation and other supportive care with professional guidance.

Latest Treatment for Encephalitis in India

New types of encephalitis treatment are being explored to make treatment more targeted. One promising approach uses NMDAR Fc fusion proteins, which are designed to bind to and neutralise harmful antibodies involved in autoimmune encephalitis. This can be useful as a supportive treatment with immunotherapy. It can also reduce the need for treatments that suppress the entire immune system.

Stem cells taken from the bone marrow, umbilical cord and adipose tissue are also being studied for their potential use in encephalitis treatment. They can help control inflammation and autoimmune reactions that contribute to nerve cell damage. However, stem cell therapy for viral encephalitis is still experimental, with research focusing on establishing its safety and effectiveness.

How Long Does Encephalitis Treatment Take?

Here is an overview of the approximate duration of different encephalitis treatments, depending on the treatment types recommended by the doctor:

Treatment	Duration
Antibiotic Medicines	7 to 21 days
Antiviral Medicines (IV)	10 to 21 days
ICU Care	Multiple days to several weeks depending on the patient's health
Immunotherapy	May be required for multiple months (duration differs from patient to patient)

Encephalitis Treatment Side Effects

The side effects of encephalitis treatment depend on the medicines or therapies used and may include the following:

Kidney damage from antiviral medicines such as acyclovir.
Headache, nausea and fatigue.
Increased risk of infections with immunosuppressive medicines.
Changes in blood sugar and blood pressure with corticosteroids.
Allergic or infusion-related reactions to intravenous medicines.
Bleeding or infection-related complications from plasma exchange.
Side effects related to anti-seizure medicines, such as drowsiness or dizziness.

Lifestyle Changes for Managing Encephalitis

Making gradual lifestyle changes during recovery from encephalitis can support physical and mental well-being. Here are some suggested changes:

Get adequate rest, keeping rest periods longer and activity periods shorter initially. As recovery progresses, gradually increase activity and reduce breaks as tolerated.
Keep your diet as healthy and balanced as possible, and drink plenty of water.
Limit sugary, salty and high-saturated-fat foods, and ask your doctor about testing and treating any nutritional deficiencies.
Avoid alcohol and limit caffeine, as both may affect sleep and overall well-being.
Consider therapy or other mental health support if you are dealing with emotional or psychological difficulties during long-term recovery.

Triggers that Can Worsen Symptoms of Encephalitis

Encephalitis can get worse due to the following factors:

Not getting enough rest.
Engaging in exhausting physical activities.
Not drinking enough fluids.
Exposure to viruses or bacteria.
Having a weak immune system due to conditions like autoimmune diseases.
Taking medicines that suppress the immune system, including certain medicines used after organ transplants or for autoimmune conditions.
Taking certain chemotherapy medicines.

Encephalitis Treatment Cost

The average cost of treating encephalitis in India can be from ₹50,000 to ₹5 lakh, depending on the underlying cause and severity. Mild cases managed on an outpatient basis may cost around ₹50,000 to ₹1 lakh, while moderate cases requiring hospitalisation may cost ₹1 lakh to ₹2.5 lakh. Severe cases requiring ICU care may cost ₹2 lakh to ₹4 lakh.
