Overview 

Dementia is a widespread condition affecting over 55 million people globally. Every 3 seconds, someone in the world develops dementia.¹ It's not a single disease but a broad term describing difficulties in remembering, thinking, or making decisions, which can hinder everyday activities. Alzheimer's disease is the most prevalent form of dementia. While it mainly impacts older adults, it's essential to note that dementia isn't a natural part of ageing.²

Navigating the journey of dementia is tough. Even though it's pretty common, it's not something you can easily figure out. And sadly, there's no cure for it, and it often worsens over time. This can make life difficult for the person with dementia. But here's the thing: it's not just them who are affected. It's also the family and the people who take care of them. 

Dementia messes with a person's memory and thinking skills, and it can make everyday things like talking and moving around difficult. Watching someone you love go through this is incredibly tough. It can wear you down emotionally and physically, and it can put a strain on your relationships and your wallet.³ 

That's why it's so important to understand what dementia is all about and learn how to deal with it. By learning more about the condition and getting help from doctors, support groups, and other resources, families can make life a bit easier for their loved ones with dementia. While we might not be able to cure the disease, we can still do things to help manage the symptoms, slow down its progress, and make life better overall. With the proper knowledge and support, we can face this challenge with strength and kindness. 

Understanding dementia: what to expect?

Dementia comprises a collection of symptoms resulting from various brain-damaging diseases. It occurs when nerve cells in the brain get damaged, affecting how the brain works.⁴ The most substantial known risk factor for dementia is increasing age, with most cases affecting those 65 years and older. Other risk factors include traumatic brain injury, a strong family history of dementia, and co-morbidities such as hypertension, diabetes, etc.⁵ 

We often group dementia based on what they have in common. One of the most common types is Alzheimer's disease, which brings memory loss and personality changes, sometimes running in families.⁴ Another one is vascular dementia, caused by poor blood flow, especially in folks with diabetes or high blood pressure. Sometimes, people have mixed dementia, where different types are present together, making symptoms overlap. And surprisingly, some cases of dementia can be reversed, caused by things like medicine side effects or not getting enough vitamins.⁵ That's why it's crucial to check for these causes when diagnosing dementia carefully. 

Symptoms of dementia

The symptoms vary depending on which part of the brain is affected. It's important to know that dementia can affect people in different ways. These symptoms typically deteriorate progressively and encompass:⁶

• Memory loss: forgetting recently learned information or even something as common as what they had for dinner last night 
• Confusion and disorientation: getting lost in familiar places, lose track of time, or forget where they are or even how they got there 
• Requiring assistance with daily activities: challenges in completing familiar tasks, such as cooking a meal or managing finances 
• Difficult communication: struggling to find the right words, follow or join conversations, understand speech, and comprehend simple things and tasks 
• Changes in mood or behaviour: becoming easily confused, suspicious, depressed, fearful, or anxious 

Diagnosis

To determine whether someone has dementia, a doctor can perform tests to assess their memory, attention, and thinking skills. They might also perform a physical check-up and some blood tests. Sometimes, they use special scans like CT or MRI to examine the brain and determine whether there's a reason for the problems. These tests help to determine whether the symptoms are caused by dementia or something else.⁷

Getting a diagnosis is crucial, even though there's no cure for it yet. Detecting it early on helps slow down its advancement, giving the person more time with better mental function. Diagnosis isn't just about knowing what's happening; it's about getting the right help and support. With a diagnosis, individuals with dementia can access treatments and services that can improve their quality of life. It's also a chance for them and their loved ones to plan, making arrangements for future care and support.⁴ So, while we can't make dementia disappear, we can take steps to make life easier for those affected by it. 

Progression of dementia 

Dementia comes in various forms, all of which worsen over time—known as dementia progression. Initially, symptoms may be mild but gradually intensify over several years. As the condition advances, individuals typically require increasing levels of assistance, eventually necessitating significant support with daily tasks. However, dementia affects each person differently, so the timing and nature of support needed varies.⁹ 

Dividing dementia progression into three stages—early, middle, and late—helps conceptualise how symptoms evolve and aid in preparation for the future. These stages, sometimes referred to as mild, moderate, and severe, reflect the extent to which symptoms impact an individual. In the mild stage of dementia, someone might start having trouble remembering recent events or names of people they know well. For example, they might forget where they put their keys or struggle to recall a friend's name during a conversation. Moving into the moderate stage, the challenges become more noticeable and start affecting their daily activities. Simple tasks like dressing or preparing meals might require more assistance as they struggle with sequencing and organisation. Finally, in the severe stage, the impact of dementia on daily life becomes profound. Memory loss is severe, to the point where they may not recognise close family members or remember significant life events. They might lose the ability to speak coherently or even communicate altogether, relying more on non-verbal cues to express their needs.⁸

How quickly dementia worsens can differ for each person and depends on a few things. The type of dementia matters a lot. For example, Alzheimer's disease usually progresses slower than other types.⁹ Age is also a factor. It tends to go slower in older folks (over 65) than younger ones (under 65). Other health issues like heart problems, diabetes, or high blood pressure can speed up how fast dementia gets worse, especially if they're not managed well.¹⁰ Sometimes, a sudden condition called delirium can also make dementia get worse faster.¹¹ 

It's hard to say precisely how fast dementia will get worse for someone. Some may need help soon after finding out, while others can stay independent. But there are things people can do to help keep their abilities for longer. Staying positive, accepting help from others, eating well, getting enough sleep, not drinking too much alcohol or smoking, and staying active mentally, physically, and socially can all make a difference.⁹ 

Navigating the journey of dementia 

For patients 

Living with dementia can feel overwhelming, but there are steps you can take to navigate this journey with greater resilience. Firstly, maintaining a positive outlook can make a significant difference. Accepting support from friends, family, and healthcare professionals can provide valuable assistance and comfort. Additionally, prioritise self-care by focusing on healthy eating, regular exercise, and quality sleep.⁹ Engaging in activities stimulating your mind, such as puzzles or hobbies, can help maintain cognitive function.¹² Remember, while dementia may present challenges, many meaningful moments remain to be cherished each day. 

What to expect from health and care services

It's essential to understand the support and services available for health needs. Since dementia affects each person differently, the level of support required varies. Usually, a care plan is created for the patient in collaboration with local services, such as memory assessment services or councils, outlining the necessary care and assistance. This plan generally focuses on preserving independence for as long as possible. There may be a designated care coordinator who ensures that support is well-coordinated, with regular reviews of the care plan and access to available assistance. Additional support may involve assessments for daily activities, assistance for caregivers, medical treatment, participation in research, and planning for future care preferences, including compassionate end-of-life care.¹³ Educating about this condition, establishing self-care and maintaining a healthy balance is essential. 

For caregivers and family

When interacting with patients who have dementia, it's essential to be patient, kind, and empathetic, understanding that they may have difficulty expressing themselves or understanding complex information. Use clear and straightforward language, speaking slowly and calmly to help them feel at ease and less confused. Maintain a gentle and reassuring demeanour, offering encouragement and support throughout the conversation. Validate their emotions and experiences, showing empathy and understanding even if their reality differs from yours. Focus on their remaining abilities and strengths, empowering them to engage in activities that bring them joy and fulfilment.^14,15

Supporting a loved one with dementia can be emotionally and physically demanding. Still, there are strategies to help navigate this journey more effectively:^16,17

• Firstly, educate yourself about the condition and available resources
• Establish a support network of friends, family members, and healthcare professionals who can provide assistance and guidance
• Practice self-care by prioritising your own physical and emotional well-being
• Seek respite care when needed to prevent burnout and maintain a healthy balance
• Communicate openly with your loved one, offering patience, understanding, and compassion throughout their journey with dementia 

Remember, you're not alone, and resources are available to help you every step of the way.
