When a person with dementia reaches a stage where they forget how to walk, it is a sign that the disease has advanced to a very late phase. At this point, the brain is no longer able to send the right signals to control movement, balance, and coordination. This loss of walking ability is often called “loss of ambulation” and it can happen in the final months or even weeks of life for many people with dementia.
Once someone can no longer walk, their body becomes much more vulnerable. They may spend most of their time in bed or in a chair, which increases the risk of infections, bedsores, and other serious health problems. The ability to swallow and eat may also decline, making it harder to stay nourished and hydrated. These changes can lead to a rapid decline in overall health.
There is no exact timeline for how long someone can live after losing the ability to walk. Some people may live for several months, while others may only survive for a few weeks. The length of time depends on many factors, including the person’s age, overall health, and whether they have other medical conditions. In general, once a person with dementia loses the ability to walk, it is a strong sign that the end of life is approaching.
It is important to remember that every person’s experience with dementia is different. Some may lose the ability to walk earlier in the disease, while others may retain this ability until the very end. The progression of dementia can be unpredictable, and the time after losing the ability to walk can vary widely from person to person.
For families and caregivers, this stage can be very difficult. Providing comfort, gentle care, and support becomes the main focus. Medical professionals can help manage symptoms and ensure the person is as comfortable as possible during this time.
