A palliative approach to dementia care, which supports the patient and their family from diagnosis to the end of life across all care settings, is crucial to optimising quality of life for dementia patients. Read all about how general practitioners have a key role in supporting patients and their caregivers in every phase of the dementia journey.
In Singapore, one in ten people above the age
of 60 suffers from dementia. This corresponds to
approximately 82,000 people in 2018, and this number
is projected to increase to 152,000 by 2030.a
This article highlights the palliative approach to
dementia care and emphasises early advance care
planning (ACP) to facilitate treatment decisions in the

A validated and commonly used prognostication
tool for Alzheimer’s disease (AD) dementia is the
Alzheimer’s Functional Assessment Staging Test (FAST) scaleb (Table 1) . This provides an overview of the disease course in AD, in which a patient who has
reached FAST stage 7a is likely to have a prognosis of
less than six to 12 months.Table 1 Adapted from Medical Care Corporationb
1. Upon Diagnosis of Dementia
Breaking the diagnosis
At diagnosis, patients are faced with the prospect
of loss of identity, abilities and independence. Their
families are also confronted with the potential loss of
their relationship with the patient and the uncertainty
of future caregiving burden.
As such, a sensitive approach (e.g., utilising the
SPIKES communication model1 as in Case Vignette
A) to breaking bad news of the diagnosis of dementia
The GP, Dr A, diagnoses Mdm L with dementia. He sits alongside Mdm L and maintains eye contact with her.
Asking open-ended questions
He asks her open-ended questions about how she wants to receive information: "Would you like to hear everything that is going on, or just the big picture? Do you want other people around you when you are receiving information, or would you prefer to hear the news by yourself?”
Mdm L says she would like to hear everything that is going on, with her son who is next to her.
Dr A asks her what she thinks is causing the symptoms of forgetfulness and difficulty with cooking. Mdm L is silent.
Dr A asks, “After hearing your story and examining you, I would like to talk to you about what is going on. Would that be OK?” Mdm L nods.
Dr A says, “I’m afraid I have some difficult news to share.” He stops to look at Mdm L, who remains silent and looks expectantly at him. “I’m concerned that you have dementia.” Mdm L looks sad.
Dr A says, "I can see that this is making you sad. What is the most difficult part of this for you?” Mdm L says she is worried about being a burden to her son, as he has already been helping her more in the past year, despite being busy with his work and children.
Dr A says, "I hear your worry about being a burden. This is something many patients worry about. But, what if instead of your son, it was you who were his caregiver – would you feel that it is a burden or an honour to care for someone you love?”
Mdm L’s son adds, “Mom, you are not a burden. If I know how to help, it is better than now when I feel so helpless and worried about you.”
Dr A then asks Mdm L if she is ready to discuss the treatment plan.
2. In the Earlier Stages of Dementia
Symptom management and caregiver support
Treatment of dementia in the earlier stages is usually
Pharmacological use of cholinesterase inhibitors
(e.g., donepezil, rivastigmine) and NMDA receptor
antagonists (e.g., memantine)
Consider stopping the agents if the patient is
unable to tolerate them due to side effects,
or if the patient demonstrates a greater-than-
expected decline after at least one
therapeutic trial (for at least six months, with
at least eight weeks of maximum / most
Consider stopping other drugs that may
exacerbate cognitive impairment (e.g.,
These include optimising cardiovascular risk
factors, regular aerobic exercise, engaging
the patient in cognitively-demanding leisure
and social activities and a Mediterranean diet.
Treatment of behavioural and psychological
symptoms of dementia (BPSD)
Extensive resources addressing the various
BPSD have been made available online
by organisations such as the Agency for
Integrated Care and Dementia Singapore.c-j
Another helpful resource is an article in the
July 2021 issue of Defining Med entitled ‘How to Manage Behavioural and Psychological
Symptoms of Dementia’.k
Caregiver education and support
Caregivers may require continued clarification
of their concerns, including those regarding
the patient’s medication regimen, which
should be simplified wherever possible.
Consider introducing caregivers to caregiver
support groupsl, as well as referrals to nurses, physical therapists and occupational
therapists for caregiver training, assistive aids
and adaptive strategies in caregiving.
Where caregivers are not able to meet the
patient’s care needs on their own or need
respite, available care options include:
Day care or nursing home respite carem
(e.g., dementia day care)
Private hourly-rated caregivers
(e.g., Jaga Me, Homage, Comfort Keeper,
Home personal care, meals-on-wheels,
and medical escort – home-based
services which help with one’s ADLs, meal
deliveries or escort/transport to medical
If the patient has symptoms refractory to the
GP’s efforts, consider referral to a neurologist,
geriatrician or psychiatrist for shared care.
In addition to optimising medical treatment, the
specialist can offer a multidisciplinary team
approach with the nursing and allied health
teams for swallowing, nutrition, physical and
occupational therapy assessments, as well as psychosocial and spiritual care.
Advance care planning
While the patient still has mental capacity, ACP
(illustrated in Case Vignette B) including specific
discussions on dysphagia management would help
to ensure that subsequent medical care is consistent
with the patient’s preferences.
Patients are also advised to appoint a lasting power
of attorney (LPA).n
Advance care planning
Dr A did ACP over time, pacing with Mdm L and her
son, and provided them with a ‘road map’ so they
understood about her current FAST staging, signs
to look out for that would suggest progression
to a more advanced stage, the pace of disease
progression, and where she was heading in terms
of her function relating to ADLs, cognition and communication.
Dr A also kept Mdm L and her son informed on
the management options for dementia and the
symptoms that she was experiencing.
Fulfilling the patient's wishes
Dr A ensured that the present and future medical
care decisions were aligned with their goals of
care, at times negotiating on behalf of Mdm L or
Towards the end when Mdm L had no mental capacity to make decisions on her medical care,
her son was grateful that he knew what she would
She had told him she wanted to have her meals
orally, and that should she be reliant on others
for her toileting needs or unable to communicate
meaningfully through gestures, she would want
medical care to focus on her comfort rather than prolongation of life.
3. In the Later Stages of Dementia
In severe dementia (from FAST stage 7),
communication difficulties and resistance to care
and feeding may become more prominent than
BPSD, with increased frequency of infections,
complications of immobility and malnutrition.
Physicians may have to decide on feeding
tube insertion, hospitalisation and intravenous medications – interventions that may cause
discomfort to the patient without bringing any
If an ACP has not been established, discuss goals
and extent of care with the patient’s close family
members who have insight into the patient’s likely
Stopping non-essential medications
Stop cholinesterase inhibitors / memantine by tapering over two to three weeks when there is no
meaningful interaction between the patient and
others/family. If decline is observed temporally
to medication discontinuation, the drug can be gradually re-introduced.
Also consider stopping other medications that
are no longer beneficial when life expectancy is
very limited (e.g., vitamins, statins, antithrombotics,
Assess for pain with a rating scale for patients who are unable to communicate, such as the Pain
Assessment in Advanced Dementia Scaleo.
The scale is also useful for caregivers to determine
if patients are experiencing discomfort – it teaches
that the patient can express discomfort though facial
expressions / body language such as laboured breathing, groaning or crying, looking tense,
restlessness, clenching fists, drawing up knees, or
pulling / pushing / striking out.
Treat the underlying cause of pain where possible.
Consider regular analgesia such as regular
paracetamol if pain is frequent, when the underlying
aetiology is unknown or irreversible.
Managing dysphagia and food refusal
Improve food intake by ensuring adequate fluids,
enhancing taste and liberalising diet based on the patient’s preferences. After addressing reversible dental and medical causes, food refusal may
characterise the end stage of dementia. The poor
appetite and associated weight loss may distress
Considerations for providing nutrition with a feeding
tube would include the following:
Aspiration pneumonia is the most common
cause of death in dementia.
Inserting a feeding tube is a medical intervention.
Feeding tubes do not eliminate the risk of aspiration (e.g., from saliva) and are not
associated with improvement in mortality.
Patients may reject feeding tubes and the
resultant agitation may require physical and
Compared to tube feeding, careful oral feeding
offers similar outcomes in aspiration pneumonia,
functional status, comfort and mortality rate.
For patients at high aspiration risk but who do
not refuse oral feeding, tasting food may be one
of the patient’s few remaining pleasures. Oral
feeding may also be a time for socialisation with
When oral intake is poor, families of patients
without a feeding tube may second guess their
decision. Be available to offer continued support.
If a feeding tube is inserted, establish clear goals
(e.g., to continue treating infections with oral
antibiotics and avoid hospitalisations, while the
patient is still alert) and regularly re-evaluate if
goals are being met.
If the patient’s prognosis is less than one year,
consider a referral to hospice home care.p
The referral criteria include:
The hospice home care team would visit patients
in their homes and provide caregivers with after-hours
support in the event of emergencies. Inpatient
hospice may be considered if patients cannot be
adequately managed at home.
In the event of demise, family members can
be referred to bereavement support services if
