Dr Sherilyn Tan (Clinical Neuropsychologist)

As a Clinical Neuropsychologist, I help adults – including older adults – understand and manage changes in their thinking, reasoning, memory, and attention. Many people come to see me because they’re feeling forgetful, finding it harder to focus, or wondering whether stress, mood, sleep, menopause, sporting injuries, or medical issues may be affecting their thinking. My goal is to provide clear answers and practical strategies so you feel informed, confident, and equipped to use your strengths in daily life – and to seek further support where appropriate.
