Dementia Activities And Exercise

Overview

Dementia is a group of symptoms that affect memory, thinking, mood and daily life. It is caused by diseases that damage the brain. Activities and exercise are not a cure, but they can help a person with dementia stay active, sleep better, feel less low or anxious, and keep connections with others. The best plan is one that is safe, enjoyable and adapted to the person's abilities and energy.

Dementia is common, especially in older adults. Millions of people around the world live with it. Many people with dementia and their carers find that simple daily activities and regular movement improve quality of life.

Most people with dementia are older adults, but younger people can get it too. Dementia affects the person, their family, friends and carers. Activity and exercise plans should involve the person with dementia as much as possible and consider the needs of carers.

Symptoms

Common symptoms

• Memory loss that affects daily life, such as forgetting recent events or repeating questions.
• Difficulty planning, solving problems or following steps, such as cooking or paying bills.
• Trouble finding words or following conversations.
• Getting lost in familiar places or being unsure of the time or day.
• Changes in mood, behaviour or personality, such as irritability, worry or withdrawal.
• Difficulty with everyday tasks like dressing, washing or managing medicines.

Symptoms in children

• Dementia in children is very rare. If a child has lasting confusion, loss of skills, or big changes in memory or behaviour, they should be checked by a doctor. These signs are usually caused by other conditions, not dementia.

Symptoms in older adults

• Dementia is more common as people get older. Signs include memory slips that affect daily life, trouble planning, word-finding problems, getting lost, and mood or behaviour changes.
• Older adults may also have other health problems, such as arthritis, heart disease or hearing loss. Activity and exercise should be adapted to energy, mobility, hearing and vision.
• A sudden change in confusion or behaviour in an older adult can be a sign of infection, pain, constipation, dehydration or a side effect of medicine. Ask a doctor for advice.

Causes

Main causes

• Dementia is caused by diseases that damage brain cells. Alzheimer's disease is the most common cause.
• Other causes include vascular dementia (from reduced blood flow to the brain), Lewy body dementia, and frontotemporal dementia.
• Many people have more than one brain disease contributing to dementia. This is sometimes called mixed dementia.
• Some memory and thinking problems are caused by other things, such as depression, infection, thyroid problems, vitamin deficiencies or medicine side effects. These need a doctor's review.

Risk factors

• Getting older is the biggest risk factor for most dementias.
• Family history and genetics can play a role in some types of dementia.
• Heart and blood vessel health matters. High blood pressure, high cholesterol, diabetes and smoking are linked to higher risk.
• Hearing loss, low social contact, physical inactivity, depression and not using the mind in challenging ways may add to risk.
• Head injury, especially repeated injury, is linked to some types of dementia.

When to see a doctor

See a doctor urgently if:

• A sudden change in confusion, behaviour or walking ability.
• A fall with injury, head injury, or new pain.
• Signs of infection, dehydration or not eating and drinking.
• Severe agitation or distress that is hard to manage safely.
• Thoughts of self-harm or suicide, or danger to others. Seek emergency or crisis help immediately.

Book a routine appointment if:

• Memory or thinking changes that affect daily life, work or safety.
• Changes in mood, sleep, appetite or interest in activities.
• Difficulty joining in activities or exercise because of pain, tiredness, dizziness or low confidence.
• A carer feeling stressed, exhausted or unsure how to support activity and exercise.
• Questions about what activities are safe and how to adapt them.

Diagnosis

There is no single test for dementia. A doctor will ask about changes in memory, thinking and daily life, and speak with someone who knows the person well. They will check health, medicines and mood, and may do memory and thinking tests. The aim is to find the cause of symptoms and rule out other treatable problems.

Tests that may be done

• Questions about memory, thinking, mood and daily activities.
• Memory and thinking tests done in clinic or at home.
• Blood tests to check for other causes of confusion.
• A review of medicines, including over-the-counter medicines.
• A brain scan in some cases.
• An assessment by an occupational therapist or physiotherapist to help plan safe activities and exercise.

What to expect at your appointment

The assessment may take more than one visit. Bring a list of medicines and, if possible, a family member or friend who can share what they have noticed. After the assessment, the doctor should explain the findings and discuss support, activity ideas and safety. Ask questions and take notes.

Treatment

There is no cure for most dementias, but much can be done to support daily life, mood, thinking and safety. Activity and exercise are important non-drug approaches. They should be enjoyable, regular and adapted to the person. A doctor, nurse, occupational therapist or physiotherapist can help build a safe plan.

Self-care at home

• Keep a simple daily routine with a mix of rest, movement, meals and pleasant activities.
• Choose activities the person enjoys and can still do, such as folding laundry, listening to music, looking at photos, gardening, walking or gentle chair exercises.
• Break tasks into small steps and give one instruction at a time.
• Plan activities at the best time of day, when the person is most alert and calm.
• Make the home safe: good lighting, clear paths, non-slip mats, and no loose rugs.
• Offer drinks and snacks regularly, especially in warm weather or during activity.
• Watch for tiredness, pain, hunger, thirst or needing the toilet, as these can cause distress.
• Involve family, friends and carers in activities to reduce isolation.

Medical treatments

Doctors may offer treatments that can help with memory, mood, sleep or behaviour in some types of dementia. These are started and checked by a specialist. They are not a cure and must be balanced against benefits and risks. Never start, stop or change any medicine without advice from a doctor or pharmacist. Non-drug support, activity and exercise are also key parts of care.

When is surgery considered?

Surgery does not treat dementia. It may be needed for another health problem, such as a hip fracture or injury. The care team will weigh the risks and benefits, including the chance of confusion after surgery. Ask the team to explain the plan in plain words.

Living with this condition

Focus on what the person can do, not what they cannot. Keep activities short, simple and flexible. A ten-minute walk, a singalong, sorting socks or watering a plant can all count. Use reminders, labels and visual cues. If an activity causes frustration, stop and try something calmer. Safety and dignity matter more than finishing the task.

Lifestyle tips

• Build gentle movement into the day, such as walking to the kitchen, chair exercises, dancing to music or stretching.
• Keep social contact through family visits, phone calls, community groups or memory cafes.
• Protect sleep with a regular bedtime, daylight exposure and less caffeine late in the day.
• Avoid too much background noise and clutter, which can make activities harder.
• Plan for outings with a companion, identification and a charged phone.
• Ask for help from carers, friends and local services before you feel exhausted.

Diet and exercise

A balanced diet with plenty of vegetables, fruit, whole grains, beans, nuts and oily fish can support heart and brain health. Drink enough water. Exercise should be regular and gentle, such as walking, chair-based movement, tai chi or dancing. Build up slowly. Stop if there is chest pain, severe breathlessness, dizziness or unusual pain, and seek medical advice. A physiotherapist can suggest safe exercises for balance, strength and mobility.

Mental health and emotional wellbeing

Dementia can cause frustration, sadness, anxiety and grief for the person and their carers. These feelings are common and deserve support. Activity and social contact can help mood, but they are not a substitute for professional help. If you or someone you care for has thoughts of self-harm or suicide, call your local emergency number or a crisis line right away. Ask a doctor about counselling, support groups and respite care.

Prevention

Dementia cannot always be prevented, and some risk factors cannot be changed. But looking after heart and brain health may lower risk or delay symptoms. Regular physical activity, social contact, a healthy diet, not smoking, limiting alcohol, protecting hearing and managing blood pressure and diabetes are all helpful. Activities and exercise also support quality of life for people who already have dementia.

Vaccines

There is no vaccine for dementia. Keep up with routine vaccines recommended for your age and health, as infections can worsen confusion and overall health.

Screening programmes

There is no routine screening test for everyone. If you or family notice memory or thinking changes that affect daily life, ask a doctor for an assessment. Screening for heart and blood vessel health, hearing and vision is also important.

Complications

If left untreated

• Without support, people with dementia may become less active, lose strength and balance, and have more falls.
• Lack of meaningful activity can lead to boredom, agitation, low mood, poor sleep and withdrawal.
• Carers can become exhausted and isolated without help.
• Untreated pain, infection, constipation or dehydration can make confusion and behaviour much worse.

Long-term outlook

Dementia affects each person differently. Many people live well for years with the right support. Activities and movement can improve mood, sleep, strength and connection. Focus on small daily pleasures and what the person can still do. Ask for help early, and review the plan as needs change.
