Reduce visual clutter by using a plain, steady background, clear lighting, and a close view of the speaker's face. These changes can help a person with dementia or aphasia focus on facial expressions, gestures, and spoken words during a video call. Aphasia is a language disorder that can affect speaking, understanding, reading, and writing. It may develop when Alzheimer's disease or another dementia affects the brain's language areas, according to the National Institute on Deafness and Other Communication Disorders.

Why visual clutter can disrupt communication
dementia can make it harder to find words, organize thoughts, follow long conversations, and block out background noise. The National Institute on Aging identifies each of these changes as a possible communication barrier in Alzheimer's disease. A cluttered screen adds more information to sort through.
Shelves, moving people, animated effects, patterned walls, and pop-up notifications may compete with the speaker's face. Aphasia creates a different but overlapping challenge. When words are difficult to understand or produce, lip movements, expressions, gestures, and visual aids may carry more of the message. Anything that obscures those cues can make the exchange harder.
Choose a simple background
Sit in front of a blank or nearly blank wall. A slight contrast between the wall and your clothing can make your outline easier to distinguish. Use a real, uncluttered setting when possible.
The Alzheimer Society of British Columbia warns that busy or glitching virtual and blurred backgrounds may disorient some people or make parts of the speaker disappear. before the call, check the camera preview: A steady blur can be useful when the room cannot be simplified. Stop using it if the person seems distracted by flickering edges or disappearing facial features.
- Remove visible movement behind you.
- Hide distracting objects where practical.
- Avoid patterned or animated backgrounds.
- Keep the camera still.
- Close unnecessary on-screen panels and notifications.
Make the speaker's face easy to read
Position the camera so your face appears clearly and remains visible when you speak. Face a light source instead of sitting with a bright window behind you. Keep your hands visible if gestures help the conversation.
Avoid covering your mouth, especially when the other person relies on lip movements or facial expressions. Wear clothing that stands apart from the background without introducing bold, moving-looking patterns. Microsoft's accessible meeting guidance recommends a steady, high-contrast background and cautions against animated, flashing, or busy designs.
Simplify the conversation as well as the screen
Visual cleanup works best when the conversation is also easy to follow. Speak in short sentences, pause for a response, and address one idea at a time.
Give the person more than one way to understand or answer: Do not treat a delayed or unclear response as proof that the person did not understand. aphasia can interfere with expressing an answer even when the person knows what they want to say.
- Show a relevant photograph or object.
- Write a key word in large, clear letters.
- Hold a prewritten message or communication card to the camera.
- Use natural gestures.
- Offer yes-or-no choices when open questions are difficult.
What the research can—and cannot—show
A 2025 eye-tracking study found that video-conference search performance declined as backgrounds became more complex and varied. Participants were asked to locate a highlighted speaker or raised-hand icon. The finding supports reducing clutter as an accessibility measure, but it is not direct clinical evidence for dementia or aphasia.
The study involved 20 participants with normal or corrected-to-normal vision and did not measure patient communication outcomes. Use the person's response as the practical test. If a plain wall, steady image, shorter exchange, or visible communication card improves participation, keep that setup; if an effect causes confusion, turn it off.
