Claire M. O’connor is a neurologist based in Sydney, NSW, Australia. She looks after people with brain and nervous system conditions that can affect memory, thinking, speech, movement, and everyday life.
Her clinic work often involves dementia-related illnesses, including Alzheimer’s disease and frontotemporal dementia. These conditions don’t just change memory. In many cases, they can also shift personality, behaviour, and how someone finds words or understands what they hear. She also treats people living with primary progressive aphasia, where speech and language slowly become harder over time.
Neurological conditions affecting movement are another big part of her work. This can include motor neuron conditions such as ALS (also called Lou Gehrig’s disease), and primary lateral sclerosis. Symptoms can vary, but they may include weakness, stiffness, trouble with hand control, and changes in speech or swallowing. At times, people also need help sorting out what’s happening and what options might help them manage day to day.
Claire also cares for families dealing with developmental dysphasia linked to inherited causes, including familial developmental dysphasia. That usually means working through early speech and language concerns, and supporting long-term planning for school, work, and communication needs.
Over time, her practice is built around careful assessment and clear next steps. She focuses on listening to the story behind symptoms, arranging the right checks, and explaining results in plain language. Public details about her exact work history and education aren’t listed here, but her clinical work centres on neurology and long-term brain health. Information about research involvement and clinical trials is also limited on her profile, so it’s best to ask directly if trials or new studies are relevant for a specific situation.
