Dementia is a condition that many people fear. It’s not only about memory loss—it also affects thinking, decision-making, and the ability to remember important things.
Over time, dementia can make it harder for a person to live independently.
A common question is whether someone with dementia knows they have it. The answer is not simple, because dementia affects the brain in many ways, and people experience it differently.
One important term to know is “anosognosia.” This means a person is unaware of their illness—not because they are in denial, but because brain damage prevents them from recognizing it.
Anosognosia is common in Alzheimer’s disease, the most common type of dementia. People with it may not realize they have memory or thinking problems because their brain cannot process that something is wrong.
Awareness varies from person to person and often depends on how far the disease has progressed and which brain areas are affected. In the early stages, many people are aware they are having trouble with memory, words, or daily tasks.
This awareness can lead to frustration, anxiety, or sadness. Studies show that early awareness of decline can sometimes cause depression as people struggle with losing control over their mind.
As dementia progresses into middle and late stages, many lose awareness of their condition. Damage to brain areas responsible for self-awareness and judgment means they may not notice their memory problems, repeated questions, or difficulty recognizing close family members.
For some, this loss of awareness may reduce anxiety, as they no longer dwell on their decline. However, for caregivers, it can make things more challenging—especially if the person resists help or does not understand why certain decisions are being made.
Researchers have explored ways to improve awareness in dementia, using therapies and activities to gently encourage self-recognition. However, increasing awareness is a delicate matter—it might improve quality of life for some but cause distress for others.
The reality is that awareness in dementia changes over time. Some days a person might be more aware, and on other days less so. This is normal. Caregivers and loved ones can best help by showing patience, empathy, and understanding.
Whether or not a person with dementia knows they have it, the most important thing is to ensure they feel safe, cared for, and respected. Recognizing that awareness differs from person to person can help provide compassionate care that preserves dignity and supports well-being.
