The Communication 'Don'ts': What to Avoid Saying and Doing with a Person Living with Dementia

When you're caring for someone with dementia, the way you communicate can either build a bridge or create a wall. This article walks through the most common communication mistakes—like arguing, using baby talk, or correcting—that can trigger agitation, confusion, or withdrawal. The good news is that with a few simple shifts, you can reduce distress for both of you and create more peaceful, connected moments. You don't have to be perfect; every small change helps.

Key points

Never argue with a person with dementia—it escalates agitation and damages trust. Validate their feelings and redirect instead.
Never use baby talk or infantilizing language. Treat the person with the same respect you would any adult, regardless of their cognitive level.
Never correct or test their memory. This causes shame and distress. Instead, respond to the emotion behind their words.
Use short, simple sentences with one idea at a time. Ask yes/no questions and give plenty of time to respond.
Reduce distractions before communicating: turn off the TV, sit at eye level, and use gentle touch to convey care.
It is okay to make mistakes. Communicating with dementia is a learning process—be patient with yourself and keep practicing.

Why Communication Becomes So Challenging

Dementia gradually damages the parts of the brain that process language, memory, and social cues. For the person living with dementia, understanding what you say and finding the right words to respond becomes harder over time. This is not a choice or a sign of stubbornness—it is a neurological change. When a caregiver argues, corrects, or uses complex sentences, the person's brain can become overwhelmed, leading to frustration, anxiety, or what looks like a behavioral outburst. As one expert explains, many of these 'troublesome behaviors' actually come from the person's inability to understand or be understood (source [8]). Recognizing this can help you shift from frustration to compassion: the behavior is a form of communication, not a personal attack.

The Emotional Impact of Being 'Corrected' or 'Tested'

Imagine being told repeatedly that you are wrong, that you forgot something, or that you already asked that question. For someone with dementia, this can feel humiliating, confusing, and deeply distressing. Their short-term memory is failing, so they genuinely do not remember asking the same question five minutes ago. When you say, 'I already told you that,' you are not only reminding them of their memory loss—you are also making them feel criticized and powerless. This can trigger a defensive or agitated response. Experts emphasize that you should never test a person's memory by asking, 'Do you remember...?' or remind them that they have a memory problem (source [23]). Instead, the goal is to preserve their dignity and sense of safety, even if that means answering the same question ten times.

The Role of Respect and Adult Identity

A person with dementia remains an adult with a lifetime of experiences, preferences, and pride. One of the most common and damaging mistakes caregivers make is using 'baby talk'—a high-pitched, sing-song voice or infantilizing language like 'sweetie' or 'honey.' Even if the person cannot feed themselves or needs help with toileting, they are not a child. Experts in dementia care training rarely compare caregiving to parenting because adults do not want to be treated like children (source [4], [7]). Using baby talk strips away dignity and can cause the person to feel disrespected, which often leads to resistance or withdrawal. The same principle applies to activities: avoid children's coloring books and instead offer adult-level materials, like a simple puzzle or an adult coloring book (source [13]).

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

Before speaking, pause and center yourself. Take a slow breath. If you are irritable or rushed, your non-verbal cues (tense shoulders, furrowed brow) will be picked up and may trigger anxiety.
Approach from the front at eye level. Make gentle eye contact and say their name first. Keep a comfortable, slightly closer distance than usual to build trust without startling them.
Use one short sentence at a time, with one idea only. Example: instead of 'We need to leave soon, so put on your shoes,' say 'Here is your shirt.' Single steps make a task manageable.
Ask one yes/no question at a time. Instead of 'What would you like to drink?' say 'Would you like coffee?' Choices overwhelm the brain and can lead to anxiety or refusal.
After speaking, count silently to ten before repeating or rephrasing. Do not interrupt—they may lose their train of thought. A calm, patient tone encourages them to keep trying.
If the person says something incorrect, do not correct or argue. Acknowledge the feeling and redirect. E.g., if they accuse you of stealing, say 'I'm sorry you're upset. Let's look together,' then change the topic to something pleasant.
Use gentle touch on the hand or arm to ground them. Demonstrate tasks (e.g., hold up a toothbrush and mimic brushing) rather than just describing them.
Reduce distractions before speaking: turn off the TV, close the door, and sit in a quiet, well-lit room without glare or shadows.
Speak in a calm, natural voice. Do not raise your pitch—it makes understanding harder. If you need to be firm, pair it with a gentle touch.
If the person becomes agitated, stop. Offer water or change the subject. You can return to it later.

What not to do

Do not argue with or correct the person. This escalates agitation and damages dignity. Instead, respond to the emotion, not the factual error, and redirect to another topic.
Do not use baby talk or infantilizing language (e.g., high-pitched voice, 'sweetie,' 'honey'). Use their preferred name and a normal adult tone, even when assisting with care.
Do not test their memory with questions like 'Do you remember what we did yesterday?' or 'Who came to see you last week?'.

Practical tools

Gentle touch
A light touch on the hand or arm conveys care and helps ground someone when words are confusing.
Silent-count pause
After asking a question or giving an instruction, silently count to ten to give the person time to process and respond without pressure.

Why does using logic backfire with people who have dementia?

Using logic backfires because dementia impairs the brain's ability to process reasoning, so arguing or explaining facts only increases confusion and frustration. Instead, validate their feelings and gently redirect to a calm activity or topic.

What specific communication strategies can I use to avoid triggering agitation and build understanding?

Use short, simple sentences with one idea at a time, ask yes/no questions, and reduce distractions like turning off the TV before speaking. Sit at eye level, use gentle touch, and respond to the emotion behind their words rather than correcting or testing their memory.

Discuss with your clinician

If the person's agitation or aggression becomes frequent or severe, ask the clinician about possible medical causes (e.g., pain, infection, medication side effects) and whether any medication adjustments might help.

If the person has difficulty swallowing or is at risk of choking, ask the clinician about safe food textures and positioning during meals. Do not use baby talk or force feeding.

If the person is having hallucinations or delusions that cause distress, discuss with the clinician whether a referral to a geriatric psychiatrist or a dementia specialist is appropriate. Do not argue about the reality of the hallucination.

If you are considering using a communication device or app, ask the clinician or an occupational therapist for recommendations tailored to the person's stage and type of dementia.
