According to the Reisberg Scale, dementia can be categorised into seven stages, which can be further grouped into four levels:
Stages 1 to 3
Stages 5 to 6
While this scale was originally developed to assess the progression of Alzheimer's disease, it can also be used to assess other types of dementia like vascular dementia, frontotemporal dementia and lewy body dementia.
In Stage 1, while individuals display no signs of clinical dementia or memory issues, and are able to function normally, changes in the brain are taking place.
Individuals in this stage exhibit mild dementia symptoms that can look like normal age-related cognitive decline. Memory lapses such as forgetting familiar words or misplacing objects are typically not obvious enough to raise concerns at this point. Symptoms associated with stage 1 and 2 could also be just normal ageing.
In the final stage of pre-dementia, individuals exhibit more noticeable cognitive lapses, such as mild difficulty concentrating and finding the right words, decreased work performance, and increased instances of getting lost. Some individuals may also experience mild anxiety as these symptoms begin to impact their daily life.
On average, this stage lasts between two to seven years. During this time, the symptoms may become evident to loved ones and while individuals may still function independently, it is advisable for them to see a family doctor for early intervention.
This stage marks the onset of early-stage dementia, where individuals experience a range of notable cognitive problems detectable by clinical assessments. Common symptoms include:
Family members should approach the topic of dementia with sensitivity as denial is a common defence mechanism for individuals at this stage.
This stage is also known as mild dementia. By this stage, life expectancy is greatly reduced. Dementia patients should also start thinking about their Advance Care Plans (ACP).
A key indicator of mid-stage dementia is the inability to recall important basic details like a home address or the names of close family members.
Individuals who have progressed to this moderately severe cognitive decline will need some assistance to perform certain activities of daily living (ADLs). These may include basic and routine tasks such as bathing and choosing proper clothing. Additionally, they may also struggle with decision-making and may be losing track of the day and time. They may also require help with walking and sitting as their physical abilities are declining.
Full-time care is typically required at Stage 6 as individuals become increasingly unaware of their surroundings, and can no longer carry out activities of daily living (ADLs) without assistance.
More severe and pronounced symptoms such as difficulty speaking, behavioural and personality changes can also occur at mid-stage dementia. These can include:
Dementia patients may also start having issues with bladder and bowel control. Caregivers must be mindful of the demanding responsibilities of round-the-clock care and be careful to avoid caregiver burnout. Not all families are equipped to handle this type of care, so it’s important to be aware of available support services.
Options such as dementia daycare, home care, and nursing homes provide both long and short-term arrangements to assist with the care of individuals with dementia. These support services can help alleviate the strain on caregivers, and ensure the well-being of both the caregiver and their loved one.
In this advanced stage of dementia, individuals face very severe cognitive decline and are completely dependent on their caregivers, having lost all verbal ability and control of their bodily functions. Dementia patients at this stage will face difficulties with eating and swallowing, increased risk of chest infection and pressure sores due to decreased mobility.
If the cause of a person’s dementia cannot be reversed, there are many ways to prevent it from progressing and to support the well-being and independence of the dementia patient. This would help to increase their overall satisfaction and quality of life.
Medication plays a key role in the management of dementia symptoms. Find out more from your family doctor or general practitioner.
Social interactions can help boost one’s mood, reduce stress and loneliness, as well as provide mental stimulation.
Day care programmes like NTUC Health’s Fun with Friends and Inter-generational Programme offer opportunities for individuals with dementia to connect with others in a safe and supervised environment. Participants can look forward to mind-stimulating puzzles and games, light exercise routines, music and art segments, and other interactive activities that are designed to promote a sense of purpose and fulfilment.
Minor modifications to your home can help create a safer environment for a person with dementia to continue living independently.
If you are unsure of how to proceed, it can be helpful to work with an occupational therapist to assess your unique needs and challenges, and follow their recommendations for appropriate home modifications.
Advance Care Planning (ACP) is particularly important for individuals with dementia as it allows them to express their healthcare and lifestyle preferences while they still have the capacity to do so. This ensures that their medical and personal wishes are known and respected as the disease progresses.
Having an ACP in place relieves your loved ones from the burdens of decision-making based on guesswork, and helps prevent family conflicts that may arise from differing opinions on your care. Find out everything you need to know about making your ACP, and other useful care plans here.
Don't hesitate to reach out for help if you find yourself struggling to cope. Whether it’s emotional support or practical assistance you require, there are plenty of resources and care services available to give you a hand.
Home care services are an option for those who wish to age in place but require additional help with tasks like housework, meal preparation, personal care, and medication management. Home care services can help you or a loved one maintain your independence and continue living in the comfort of your own home, while receiving the care you need. Families that need help with the fees of these services can also apply for the home caregiving grant.
Furthermore, there are also many helplines and support groups that can offer a compassionate ear to those who are feeling down and lost.
