When you or a loved one is diagnosed with dementia, it’s understandable to have a lot of questions about the future. One of the most important and pressing issues is often the rate of progression. Dementia progresses differently depending on a number of factors, including the type of dementia, overall health, lifestyle and support system.
Today, we’ll explore how quickly dementia symptoms progress and how you can help your loved one through this tumultuous time.
How Dementia Progresses: A Typical Timeline
Understanding the typical timeline of dementia progression can help many families prepare for changes their loved one may face as their condition changes. While every dementia diagnosis is unique, the condition generally follows a recognisable path.
The average timeframe a person will live with dementia is eight to 10 years. However, some people can live longer due to a slower rate of progression while others may experience a more rapid decline in health.
There are three main stages of dementia: mild, moderate and severe:
Mild Dementia
The early stages of dementia, otherwise known as early onset dementia, are where symptoms are frequently mild and manageable.
Symptoms often include:
- Memory difficulties: Memory loss is one of the first signs of dementia, along with losing items or forgetting names and events. This is very common with Alzheimer’s disease.
- Planning errors: As confusion increases, planning can become more difficult and making complex decisions may prove to be challenging.
- Communication and language barriers: Talking to loved ones can become harder in the early stages of dementia, increasing feelings of isolation and loneliness. Frontotemporal dementia and vascular dementia can cause language difficulties.
- Visual difficulties: Early-stage dementia can make it harder to judge distances, increasing the risk of falls. Visual hallucinations are possible with dementia with Lewy Bodies.
- Mood or emotional changes: Dementia can leave people at risk of depression, anxiety and more emotionally vulnerable.
Many people with early symptoms can remain independent with minimal support. While it varies for everyone, stage one can last about 2 years on average.
Moderate Dementia
Moderate-stage dementia sees the initial dementia symptoms a person experiences become more pronounced. Day-to-day tasks become more challenging and the individual may need a higher level of assistance.
Common symptoms of middle-stage dementia include:
- Lack of inhibition: Individuals may behave differently than how they usually would, such as displaying overtly sexual or inappropriate behaviour.
- Sleep disturbances: Dementia can affect sleep patterns, making it difficult to fall asleep and stay asleep.
- Following loved ones: As anxiety increases, a person with dementia might begin following people they trust around the house.
- Easily Distracted: You may notice your loved one repeatedly rubbing their clothes, asking the same questions, and not believing what people tell them.
- Communication difficulties: Communication can become more difficult during mild cognitive impairment. They may struggle to find words and follow a conversation.
- Sundowning: Sundowning can cause strong anxiety later in the day, leading people to feel they’re in the wrong place, late for something important, or surrounded by strangers.
Severe Dementia
Otherwise known as late-stage dementia or advanced dementia, this is where the condition progresses into needing round-the-clock care from a professional. Unlike early symptoms, severe dementia often reduces a person’s independence and ability to carry out daily tasks without a live-in carer.
Common symptoms of advanced dementia include:
- Time shifting: It’s common for people with advanced dementia to believe they’re living in an earlier stage of their life, acting and talking as if they are younger versions of themselves.
- Language difficulties: Speaking can become more impacted, with some late-stage dementia patients losing the ability to speak altogether.
- Changes in emotions and mood: Hallucinations become more common as the stages of dementia progress, which can alter reality and cause big changes to their emotions.
- Behavioural changes: People may become more aggressive as their dementia symptoms progress, especially if they’re feeling vulnerable, scared or confused.
- Physical changes: Cognitive decline can reduce physical abilities in everyday life, such as walking, going to the bathroom and swallowing food.
Life Expectancy of People Living with Dementia
The life expectancy of people living with dementia can vary greatly and depend on a number of factors, such as:
- Their age at the time of diagnosis
- Type of dementia
- Coexisting health conditions
While dementia is often life-limiting, early diagnosis and a thorough, proactive care plan can help boost quality of life as symptoms progress.
People living with Alzheimer’s disease may live 8-12 years after their diagnosis, on average. Lewy body and frontotemporal dementia can cause faster or less predictable progression. Vascular dementia often follows a stroke or mini-stroke, which can result in a more dramatic decline.
How Quickly Does Cognition Decline in Dementia Patients?
The speed at which a person’s cognition declines after a dementia diagnosis isn’t linear. Some people may experience periods of their lives when symptoms remain steady and unchanged for years, followed by a sudden worsening of symptoms.
Others may see a steadier cognitive decline and memory loss. Factors influencing the speed of this often include genetics, social engagement, cardiovascular health, physical activity and access to specialist care.
Unfortunately, it is very difficult to determine how quickly an individual with dementia will decline. Working with experienced carers and healthcare professionals can help you quickly identify signs of progression, allowing you to put a plan in place to protect your loved one and ensure they continue to receive the best possible standard of care.
Does Progression Change with Early-Onset Dementia?
Early-onset dementia often occurs before an individual is 65 years old, and the rate of progression often differs from that of late-onset cases. While progression changes from person to person, young-onset dementia generally acts as a more aggressive form of the disease.
While symptoms follow the same general stages, younger adults often experience faster decline, especially regarding language difficulties and behavioral changes from frontotemporal dementia.
Some individuals with early-onset dementia only survive 3-6 years after diagnosis, although the average life expectancy of someone with this condition is 5-10 years after diagnosis.
Typical life expectancies of types of early-onset dementia:
- Alzheimer’s Disease: Approximately 8-10 years
- Frontotemporal Dementia: 6-8 years, or 2-3 years if combined with motor neurone disease
- Vascular Dementia: Around 5 years
- Dementia with Lewy Bodies: Approximately 6 years, with increased risk of falls and infections
