John E. Parratt is a neurologist based in Sydney, NSW, Australia. He looks after people with a wide range of nervous system problems, including conditions that can affect the brain, spinal cord, nerves, and vision. Neurology can be confusing and scary at first, so the focus is usually on making sense of what’s happening and what the next steps are.
Many of his patients are dealing with multiple sclerosis (MS), including relapsing multiple sclerosis (RMS), tumefactive MS, and other MS-related changes. He also cares for people with optic neuritis and neuromyelitis optica. When vision issues or eye pain show up along with other neurological symptoms, that’s often where he spends a lot of time early on.
His work also covers other inflammatory and neurological conditions such as transverse myelitis, encephalitis, neurosarcoidosis, and hearing loss linked to neurological causes. At times, patients come in with symptoms connected to optic and circulation problems too, such as retinal artery occlusion.
Some cases are more rare, but they still matter. Examples in his practice include Susac syndrome, POEMS syndrome, and Alpers-Huttenlocher syndrome. He also sees people with alternating hemiplegia of childhood, apraxia, and Pelizaeus-Merzbacher disease. In addition, there are patients with syndromes where immune and body-wide issues can overlap, like common variable immune deficiency and collagenous colitis. Autoimmune thyroid problems like Hashimoto thyroiditis and skin conditions like psoriasis can show up as part of the wider health picture too.
When symptoms come and go, or when they change over time, it helps to have clear coordination and steady follow-up. John Parratt works with patients to understand the pattern of their symptoms across the nervous system, so they can be managed in a practical way, not just in theory.
