About of Sudarshini Ramanathan

Sudarshini Ramanathan is a Neurologist based in Sydney, NSW, Australia. She works with people who have problems with the brain, nerves, and the spinal cord. Neurology can be scary, and symptoms can change over time, so care often needs to be steady and practical.


In clinic, Sudarshini looks after patients with conditions that affect how the nervous system works. This can include multiple sclerosis (MS), optic neuritis, transverse myelitis, and neuromyelitis optica. She also treats people who have myelitis and other inflammatory or immune-related brain and nerve conditions. At times, this can involve managing flare-ups, new symptoms, and the after-effects that can follow.


She also helps people with seizure conditions. That can include absence seizures and generalised tonic-clonic seizures, as well as myoclonic epilepsy. Sudarshini cares for patients where there’s a need to work out what’s going on in the brain, and then plan ongoing management. Movement and nerve pain issues may also come up, including neuralgia and movement disorders like chorea.


Some of the other neurological and immune conditions she sees include anti-NMDA receptor encephalitis, CACH syndrome, and neurosarcoidosis. She may also be involved in care for people with encephalitis, and for those affected after infections such as COVID-19, where neurological symptoms can happen. In severe, rare cases like Creutzfeldt-Jakob disease, specialist input is important for helping families understand what to expect.


Eye and brain inflammation can overlap too. For example, uveitis can be linked with immune system issues, and it can sit alongside neurological symptoms in some cases. Sudarshini’s care focuses on connecting these dots so the treatment plan matches what the body is doing.


Experience and education details aren’t listed here, but the work spans a broad mix of neurological problems, from seizure disorders to immune and inflammatory conditions. Research and clinical trial details also aren’t provided at this time, so any involvement in trials can’t be confirmed from the information available.


Overall, Sudarshini Ramanathan’s role is about clear diagnosis, careful follow-up, and supporting people through long-term nerve conditions. Neurology is not one-size-fits-all, and her approach reflects that.
