Getting to the clinic
Dr Chong Mei Sian is Medical Director of The Geriatric Practice, located at Royal Square Medical Centre in Novena. The nearest rail station is Novena MRT (NS20) on the North-South Line, within easy reach of the medical centre; the walk is short and largely sheltered, which suits many older patients, though those with limited mobility may prefer a taxi or ride-hailing car to the entrance. Drop-off points are available, and several bus routes serve the Thomson Road and Novena area with stops nearby. Royal Square sits within the cluster of medical buildings around Novena, so directions are straightforward once you reach the station.
If you are driving, Royal Square has a paid visitor carpark; arrive a little early for busy morning clinics and allow time for Novena’s weekday traffic. Drop-off bays near the building entrance let a family member set down an older patient before parking, which is often helpful for those who tire easily. The clinic can confirm its exact level when you book, and it is worth letting reception know in advance if a patient needs a wheelchair or assistance on arrival. Lifts and accessible facilities are generally available within the medical centre.
What memory and dementia care covers
Dr Chong’s focus is on memory and dementia, or cognitive disorders, in older adults, with related interests in delirium and sleep problems. Cognitive disorders cover a range of conditions in which memory, thinking, language, attention or judgement decline, including the various forms of dementia such as Alzheimer’s disease and vascular dementia, as well as mild cognitive impairment and reversible causes of confusion. Delirium, an acute and often fluctuating confusion usually triggered by illness, medication or other stresses, is an important and frequently treatable problem in older people.
Assessment in this field aims to clarify whether a memory or thinking problem is present, how significant it is, what is causing it, and what can be done. Some causes are reversible or treatable, so a careful evaluation matters. Care extends beyond diagnosis to supporting both the person and their family, managing symptoms, addressing safety, and planning ahead. Sleep problems, which are common in older adults and can affect cognition and mood, may be assessed alongside memory concerns.
What to expect at a consultation
A consultation for memory concerns is usually detailed and may take time. The doctor will ask about the changes noticed, when they began, how they have progressed, and how they affect daily life. Information from a family member or close companion is often invaluable, as the person themselves may not be fully aware of the changes. The doctor will also review other medical conditions, medications, mood and sleep.
The assessment commonly includes cognitive testing, a physical and neurological examination, and a review of medications that might affect thinking. Investigations may include blood tests to look for reversible contributors and, in some cases, brain imaging. The doctor then discusses the findings, explains the likely diagnosis, and sets out a plan that may include treatment, support for the family, safety advice and follow-up. Time is usually given for questions, as understanding the condition helps families plan and cope.
Preparing for your appointment
Helpful items to bring include:
- Photo identification and any GP or polyclinic referral letter.
- Previous medical records, blood results and any brain scans.
- A complete list of all medications and supplements, or the actual boxes.
- Glasses and hearing aids if used, as sensory problems can affect testing.
- A written account of the memory changes noticed and a list of questions.
It is very helpful to bring a family member or close companion who can describe the changes and the person’s daily routine. Noting specific examples of memory or thinking difficulties, with rough dates, gives the doctor a clearer picture than general impressions alone.
After your consultation and follow-up
After the visit you may need to wait for blood results or a brain scan before a diagnosis is confirmed; these are usually discussed at a follow-up appointment. Memory and dementia care is typically ongoing, with reviews to monitor progress, adjust treatment, and support the family over time. Referrals to other services, such as community support or allied health, may be arranged. Continuity with the same doctor helps track changes and maintain a consistent plan. You can seek a second opinion at any stage. Seek urgent care for sudden confusion, a marked or rapid change in behaviour, or symptoms such as weakness or slurred speech that could indicate an acute problem.
Booking, referrals and fees
For a private consultation you generally do not need a referral, though a GP or polyclinic referral may help if you later seek subsidised care in the public system. Some investigations may attract MediSave use within set limits for eligible patients, while consultations are usually paid out of pocket; these rules change periodically, so confirm current eligibility with the clinic. As costs depend on the exact tests involved, ask for an estimate and check your insurance coverage before proceeding.
Common questions
Is memory loss always dementia?
No. Memory problems can have many causes, some of them reversible, such as medication effects, thyroid problems, low mood or sleep disturbance. A proper assessment helps distinguish these.
What is the difference between delirium and dementia?
Delirium is an acute, often fluctuating confusion usually triggered by illness or medication, and is frequently treatable. Dementia is a more gradual, longer-term decline. The two can coexist.
Should a family member attend?
Yes, and it is strongly encouraged. Family observations are often essential to an accurate memory assessment.
Can anything be done after a dementia diagnosis?
Yes. Treatment, symptom management, family support, safety planning and follow-up can all help. Care focuses on maintaining function and quality of life.
