Lewy Body Dementia: A Guide for Family Caregivers

Leave a Comment / Understanding Dementia / By

This article provides a clear overview of Lewy body dementia for those who are caring for a loved one with dementia at home. It briefly explains what happens in the brain during the illness, how it differs from other types of dementia, and what symptoms characterize Lewy body dementia. Additionally, it offers practical advice on managing difficult situations, creating a safe home environment, and how to help someone with dementia in their daily life.

Lewy body dementia is a less well-known but common type of dementia that affects many families. If you are caring for a loved one at home who has been diagnosed with Lewy body dementia (or is experiencing similar symptoms), it is important to understand what to expect.

What happens in the brain?

In this disease, tiny abnormal deposits—called Lewy bodies—appear in the nerve cells of the brain. Over time, these damage and destroy the nerve cells, leading to a decline in mental abilities and movement.

How is this different from other dementias?

The symptoms often resemble those of Alzheimer’s disease, but there are some key differences:

  • Memory is often less affected in the early stages.
  • The mood of your loved one with dementia is very fluctuating: it can change from one day to the next, or even from one hour to the next. Sometimes they seem relatively well, and the next moment they become completely confused.
  • Visual hallucinations (seeing things) are common.
  • Movement increasingly resembles the symptoms of Parkinson’s disease: increased muscle stiffness, tremors at rest, slowed movement, and reduced facial expressions.

What symptoms should you look out for?

1. Fluctuating state

One of the hardest things for family members is that the person is in a “fluctuating” state. They might be talkative one day and barely responsive the next. Their attention and alertness change significantly and quickly throughout the day—they may be fully alert and vivid, then suddenly become withdrawn, confused, and lose their sense of direction.

2. Hallucinations

It is common for someone with dementia to see things that aren’t there, such as people or animals. These are completely real to them, so it is not worth arguing. Acoustic hallucinations are also associated with this type of dementia: they may hear non-existent voices, music, or noises.

3. Movement problems

Lewy body dementia affects movement, so physical abilities vary greatly. Watch for the following:

  • Slow, unsteady gait
  • Stooped posture
  • Risk of falls and accidents
  • Hand tremors

4. Sleep disturbances

Many “act out” their dreams: talking, shouting, or moving during sleep. Some living with dementia may fall into a deep sleep for entire days.

5. Other symptoms

What can the family expect?

Unfortunately, the disease is currently incurable and progressively worsens. It usually advances over several years, but the pace varies from person to person.

How can you help at home?

Patience and flexibility are key

Since the condition can change quickly, it is hard to adapt to their current state. What worked yesterday might not work today.

Don’t argue about hallucinations

If your loved one “sees someone,” don’t try to convince them that the person isn’t there. Instead, reassure them and try to distract their attention.

Safety above all

  • Remove small furniture and rugs from the house.
  • Provide handrails where your loved one walks frequently.
  • Pay attention to nighttime lighting—use motion-sensor lamps.

Establishing a daily routine

A simple, easy-to-follow routine is not just a practical help but provides real security. Lewy body dementia affects memory, attention, and the sense of time, so the person often doesn’t know what time of day it is, what will happen next, or what is going on around them. A repetitive, predictable daily rhythm provides a steady point of reference in this uncertainty.

Consistency helps reduce anxiety and is calming. If your loved one gets up, eats, and goes to bed at roughly the same time, it often has a positive effect on sleep quality. It is worth including simple activities throughout the day. You don’t need to think of complicated things: a short walk, light housework, or even just looking at old photos helps someone with dementia stay active. Familiar activities they have done before are especially soothing.

It is important not to overwhelm them. Too many programs or frequent changes can easily make them confused and restless. It is better to choose fewer but regular activities. Although a stable routine helps a lot, you don’t need to stick to it rigidly. If your loved one is tired, having a bad day, or is more restless, it is better to adapt to their current state.

Many families find that confusion increases in the afternoon and evening hours. At these times, a calm, quiet environment is particularly important, and activities should wind down toward the end of the day. It also helps if we simply explain in advance what is going to happen—for example, that lunch is coming now or it will be time to rest soon. This kind of continuous, clear communication provides a sense of security.

A typical day usually follows a simple rhythm: waking up in the morning, washing and breakfast, some movement and light activity during the day, then lunch and rest, calmer activities in the afternoon, and winding down and sleep in the evening. This not only helps the person find their way through the day but also makes organization easier for relatives and reduces daily stress.

The routine, therefore, is not a strict set of rules but a kind of invisible support. It helps the person living with dementia feel less lost and remain calmer and more balanced.

Light movement

  • Short, slow walks in the apartment or around the house.
  • Gentle stretching exercises while sitting or standing.
  • “Chair exercises” (arm and leg lifts).
  • Light ball games (e.g., rolling a soft ball to each other).
  • Simple dance steps to favorite music.

Memory and attention exercises

  • Looking at old family photos and talking about them together.
  • Asking simple questions (e.g., “What was for breakfast today?”).
  • Recognizing and naming objects (e.g., kitchen utensils).
  • Recalling short poems or songs together.
  • Matching pictures or simple puzzles (with few pieces).

Listening to music or creative activities

  • Listening to favorite old songs together.
  • Coloring with simple patterns.
  • Drawing or painting freely.
  • Simple crafts (e.g., cutting paper, gluing).

In these activities, the “performance” is not what matters, but the experience and the time spent together.

Lewy body dementia is a complex condition that affects not only memory but also movement, sleep, and perception. It is very difficult for family members to live with a loved one whose mood is constantly changing, but with understanding and patience, you can greatly improve their quality of life.
