Understanding early onset dementia - what you need to know

Early onset dementia can be a confusing and overwhelming diagnosis, not just for those who receive it, but also for their families, friends and carers. By understanding what it is, how it progresses, and what to expect, you can better prepare for the journey ahead and find the right support. In this article, we break down key information about early onset dementia, including progression timelines, life expectancy, communication tips and next steps.

What is early onset dementia?

Early onset dementia refers to any form of dementia diagnosed in individuals under the age of 65. While Alzheimer's disease is the most common type, others include frontotemporal dementia, vascular dementia and dementia with Lewy bodies. Symptoms can vary but often include memory loss, difficulty concentrating, language problems and changes in behavior or mood.

How quickly does early onset dementia progress?

The progression of early onset dementia can vary from person to person, but it generally advances more rapidly than late-onset dementia. Factors like the specific type of dementia, individual health conditions and lifestyle all play a role. Some people may experience a relatively slow decline over several years, while others progress quickly within just a few. On average, the journey from diagnosis to advanced stages can take between 2 to 10 years.

What is the life expectancy of someone with early onset dementia?

Life expectancy varies based on the type and stage at diagnosis, but generally ranges from 5 to 10 years post-diagnosis. Some individuals may live longer, particularly with strong support networks and proactive health care. It’s important to focus on quality of life and meaningful engagement during this time.

Three things not to say to someone with dementia

Language matters. The wrong words can be confusing or hurtful. Here are three phrases to avoid:

1. "Do you remember...?" This can cause frustration or embarrassment if they don’t.

2. "You’re wrong." Arguing over facts rarely helps and can escalate distress.

3. "I just told you that." Repetition is a symptom, not a choice. Patience goes a long way.

Instead, use calm reassurance and focus on feelings rather than facts. For more communication strategies, see DementiaNet’s guide to talking with someone who has dementia.

Final thoughts

Understanding early onset dementia means embracing both the challenges and the moments of connection that still exist. With the right knowledge and support, individuals and families can face this journey with resilience and compassion.
