Dementia affects hundreds of thousands of people across the UK. But despite its prevalence, myths and misunderstandings still surround it. These myths can be harmful. They influence how people react, how care is provided, and how early support is sought.
Health and social care workers are on the front line. They interact daily with individuals affected by dementia and play a key role in shaping awareness. If they hold inaccurate views, it can delay diagnosis, lead to poor care, and prevent families from understanding what’s really happening.
This article explores and corrects 10 common myths about dementia. Each myth is explained and replaced with facts. These facts help guide better support and more compassionate care.
1. Dementia is a normal part of ageing
Forgetting things occasionally is a natural part of getting older. But dementia goes far beyond that. It involves long-term changes to how the brain works, often caused by diseases like Alzheimer’s, vascular dementia or frontotemporal dementia.
It’s important to note that not everyone who gets older develops dementia. Many people remain mentally sharp well into later life. Assuming forgetfulness is “just age” can lead to missed opportunities for diagnosis and support. Early detection matters. Understanding what is and isn’t normal for ageing helps care professionals make better assessments and referrals.
2. Only older people get dementia
Dementia is more common in older adults, but younger people can get it too. When someone under 65 develops the condition, it’s known as young-onset dementia. Around 70,000 people in the UK live with it, according to Alzheimer’s Society estimates.
Young-onset dementia can present differently. Symptoms may include problems with speech, mood changes, or difficulty concentrating rather than memory loss alone. Because of their age, individuals are often misdiagnosed or their symptoms are dismissed.
Care professionals must stay alert. If a person in their 40s or 50s is showing consistent cognitive changes, dementia could be the cause, even if it seems unlikely.
3. Dementia and Alzheimer’s disease are the same
The terms are often used interchangeably, but they’re not the same. Dementia is the collective name for symptoms caused by several conditions that affect the brain. Alzheimer’s disease is just one cause. It is the most common, but it’s not the only one.
There are many types of dementia. Vascular dementia follows strokes or poor blood flow. Dementia with Lewy bodies affects movement and perception. Frontotemporal dementia affects personality, language, and behaviour. Each type brings different symptoms.
Clear knowledge of these differences is essential for providing suitable care. A blanket approach doesn’t work. Tailored care depends on recognising the specific type of dementia someone has.
4. Memory loss is the only symptom
Memory loss is widely associated with dementia, but it’s far from the only sign. Many people with dementia can recall recent events but may have difficulty with tasks, language, or mood regulation.
Other symptoms include:
- Getting lost in familiar places
- Difficulty following conversations
- Misplacing items and accusing others of stealing
- Anxiety or low mood
- Hallucinations or changes in behaviour
Care professionals must look beyond memory. Emotional changes, confusion, or language issues are just as important in early detection. Focusing only on memory risks missing the broader impact of the condition.
5. Carers don’t need support
Carers often put others first. Over time, that takes a toll. Many experience stress, exhaustion, and isolation. Despite this, they rarely ask for help.
Carers need regular breaks, emotional support, and access to practical resources. That might include:
- Respite care
- Peer support groups
- Counselling
- Carer’s assessments
- Help with daily tasks
Ignoring the well-being of carers harms everyone. A struggling carer cannot provide consistent support. Investing in their health, such as by providing them with a mental health awareness course, is an investment in the person they care for.
6. People with dementia can’t live well
This belief is unfair and damaging. A dementia diagnosis doesn’t mean life is over. Many people live full lives for years after diagnosis, particularly when they have support and structure.
With the right adjustments—such as a stable routine, meaningful activities, and calm communication—people can maintain independence. Engagement through music, conversation, physical activity, and hobbies helps preserve quality of life.
Care workers play a vital role in maintaining wellbeing. Creating dementia-friendly environments and offering reassurance helps people continue to enjoy life. The focus should be on ability, not limitation.
7. Dementia always runs in families
There is a genetic component in some rare types of dementia, but for most people, family history plays a small role. In fact, the vast majority of dementia cases are not inherited.
Factors that influence dementia risk include:
- Cardiovascular health
- Physical activity levels
- Diet and alcohol use
- Diabetes and high blood pressure
- Cognitive stimulation and social activity
Reducing risk is possible by managing these factors. That means promoting good heart health, avoiding smoking, and staying mentally active. A strong family history might raise awareness, but it doesn’t determine the outcome.
8. It’s pointless to get diagnosed early
Some people think there’s no benefit in knowing. That belief is harmful. An early diagnosis helps individuals and families prepare, access help, and understand the changes ahead.
Knowing what’s happening allows people to:
- Put legal and financial plans in place
- Access local support services
- Make informed decisions about care
- Explore available treatments and therapies
It also helps reduce uncertainty. Families who understand the condition are better equipped to respond to changes in behaviour. Early diagnosis empowers, while delay causes confusion and missed chances.
9. You can’t manage the symptoms
There is no cure for dementia, but the idea that nothing helps is false. A wide range of strategies can improve life for those affected.
Medicines may reduce symptoms in some types of dementia. But non-drug approaches are also effective. These include:
- Structured daily routines
- Cognitive stimulation activities
- Music and reminiscence therapy
- Environmental adjustments
- Behavioural support
Training for carers is key. A dementia awareness training course, for example, can equip care workers with the knowledge needed to provide compassionate and informed care.
10. People with dementia are aggressive
Aggression is not a symptom of dementia. When people act out, it’s usually a reaction to confusion, fear, or discomfort. For example, someone might lash out because they don’t understand what’s happening or because they’re in pain and can’t explain it.
It’s crucial not to label individuals as aggressive. Doing so increases stigma and can lead to inappropriate responses.
Instead, professionals should:
- Recognise behaviour as communication
- Look for underlying causes, such as pain or distress
- Use calm, reassuring responses
- Adjust the environment to reduce overstimulation
Training helps professionals respond in the right way, reducing the risk of escalation and improving the individual’s experience.
