Clinical services cover a broad spectrum of conditions, including dementia, early-onset Alzheimer's, depression, sleep disorders, and panic disorder. On Friday mornings, the clinic runs specialty outpatient services for brain health and anti-aging support programs as well as BMI and body composition assessments. The clinic is open on weekday mornings and afternoons (closed on weekends and public holidays), accepts credit cards and electronic payments, and is equipped with barrier-free facilities, providing a comfortable and accessible environment for a wide range of patients.
