David S. Gillis is a neurologist based on Butterfield Street in Herston, QLD (4029). Neurology can be a confusing area, especially when symptoms come on quickly or keep returning. David looks after people with nerve and brain conditions, working to understand what’s causing the problem and what helps most in the long run.
His work covers both common and rarer neurological issues. This includes conditions linked to inflammation in the brain, such as encephalitis, including herpes simplex encephalitis and anti-NMDA receptor encephalitis. At times, these illnesses can affect thinking, behaviour, movement, or sleep, and they often need careful assessment and follow-up.
David also helps with immune-related disorders that can affect the nervous system. For example, neuromyelitis optica and transverse myelitis can cause problems with the spinal cord and vision, including optic neuritis. He also treats people with myasthenia gravis and other muscle or nerve problems, such as myositis, and conditions that can show up with muscle weakness, movement issues, or swallowing and speech changes like palatal myoclonus.
Seizures and epilepsy are another part of his clinical work. He focuses on getting a clear picture of seizure types and triggers, so treatment decisions feel grounded and practical. Over time, that can make a big difference to day-to-day life.
Some patients seen in neurology also have immune or gland conditions that run alongside nerve problems. David cares for people with conditions like common variable immune deficiency and Hashimoto thyroiditis, along with other immune system related problems such as vasculitis and antisynthetase syndrome.
There are also specific neurological diagnoses he manages, like opsoclonus-myoclonus syndrome, macrophagic myofasciitis, and teratoma of the mediastinum when it’s connected to neurological symptoms. While these can be rare, the aim is still the same: steady care, clear next steps, and support for families and carers.
David’s approach stays evidence-based and patient-centred. He brings a calm, organised mindset to complex cases, where symptoms can overlap. If the diagnosis is still being worked out, he helps guide the process step by step, so you know what’s happening and why.
