Can Dementia Make People Forget Their Pet’s Name
Dementia is a condition that affects millions of people worldwide, and it causes progressive damage to the brain that impacts memory, thinking, and behavior. One of the most heartbreaking aspects of dementia is how it can affect a person’s ability to remember the people and things they love most. This raises an important question: can dementia make people forget their pet’s name?
The short answer is yes. Dementia can absolutely cause people to forget their pet’s name, along with many other important memories and details from their lives. To understand why this happens, we need to look at what dementia does to the brain and how memory works.
Understanding How Dementia Affects Memory
Dementia is not a single disease but rather a general term for a decline in mental ability severe enough to interfere with daily life. Alzheimer’s disease is the most common type of dementia, accounting for 60 to 80 percent of dementia cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia.
The brain damage that occurs in dementia happens gradually over time. In Alzheimer’s disease specifically, two types of damage occur in the brain. First, plaques form outside of nerve cells, and second, tangles form inside nerve cells. These plaques and tangles interfere with communication between brain cells and eventually lead to cell death. This damage typically begins in the areas of the brain responsible for memory, which is why memory loss is often one of the first signs of dementia.
Research has shown that amyloid-beta, a toxic protein, accumulates in the brains of people with Alzheimer’s disease and disrupts the connections between neurons. [2] This protein buildup causes synapses, which are the tiny junctions between brain cells that carry messages, to deteriorate. When these connections are damaged, the brain cannot properly store or retrieve memories.
The Progressive Nature of Memory Loss
Memory loss in dementia typically follows a pattern. In the early stages, a person might forget recent events or have trouble remembering names and faces. They might forget why they walked into a room or struggle to recall what they had for lunch. However, long-term memories from earlier in life often remain intact longer.
As dementia progresses, the memory loss becomes more severe. A person might forget the names of family members, close friends, or even their spouse. They might not recognize people they have known for decades. In advanced stages, a person may lose the ability to recognize themselves in a mirror or remember major events from their life.
Given this pattern of memory loss, it is entirely possible and even likely that a person with dementia could forget their pet’s name. The name of a pet is a relatively recent memory for most people, especially if the pet was acquired in adulthood. Even if the pet has been part of the family for many years, the specific name might be forgotten while the general awareness of having a pet remains.
How Pets Fit Into Memory and Emotion
Pets hold a special place in people’s lives and in their memories. For many people, a pet is a daily companion, a source of comfort, and a beloved family member. The relationship with a pet involves multiple types of memory: semantic memory (facts about the pet, like its name), episodic memory (specific events with the pet), and emotional memory (the feelings associated with the pet).
Dementia can affect all of these types of memory. A person might forget the pet’s name but still recognize the pet itself. They might forget specific events they shared with the pet but still feel a sense of comfort and familiarity when the pet is near. This is actually one of the remarkable things about the human-animal bond: it can persist even when other memories fade.
Research has shown that pets can have therapeutic benefits for people with dementia and Alzheimer’s disease. Therapy dogs have been found to reach residents with dementia in ways that other people sometimes cannot. [5] This suggests that the emotional connection to animals can remain strong even when cognitive abilities decline.
The Specific Challenge of Names
Names are a particular type of memory that can be especially vulnerable in dementia. Names are arbitrary labels that we attach to people and things. Unlike other memories that are tied to emotions or sensory experiences, names are often purely semantic information. This makes them more susceptible to being forgotten as dementia progresses.
A person with dementia might remember that they have a cat and might even remember specific events with that cat, but they might not remember the cat’s name. They might call the cat by a generic term like “kitty” or “the cat” instead. Or they might call the cat by a name that is not correct, perhaps confusing it with a previous pet’s name.
This can be particularly difficult for family members and caregivers. They might feel hurt if a loved one forgets their pet’s name, even though they understand that the memory loss is due to the disease and not a reflection of how much the person cared about the pet.
The Connection Between Feline Dementia and Human Dementia
Interestingly, research has revealed that cats themselves can develop dementia, and this feline dementia closely mirrors Alzheimer’s disease in humans. [2] Researchers at the University of Edinburgh studied 25 cats that had shown signs of confusion, disrupted sleep, and increased vocalization during their lives. They found a buildup of amyloid-beta, the same toxic protein found in human Alzheimer’s disease. [2]
This research is significant because it shows that the mechanisms of dementia are similar across species. The same protein accumulation that causes memory loss in humans also causes memory loss in cats. This suggests that the fundamental biological processes underlying dementia are consistent, whether in humans or animals.
In cats with feline cognitive dysfunction, the symptoms include wandering aimlessly around familiar spaces, forgetting the location of the litter box or feeding station, vocalizing more than usual at night, and losing interest in toys and activities that once stimulated them. [1] These symptoms are remarkably similar to the symptoms of dementia in humans, including memory loss, disorientation, and changes in behavior.
The fact that cats can develop dementia that is so similar to human dementia provides researchers with valuable insights into how the disease works and how it might be treated. By studying naturally occurring dementia in cats, researchers can observe disease progression without creating artificial models or subjecting animals to invasive experiments. [2]
What Happens When Someone with Dementia Forgets Their Pet’s Name
When a person with dementia forgets their pet’s name, several things might happen. The person might still recognize the pet and feel affection toward it. They might still enjoy the pet’s company and find comfort in petting the animal or watching it play. However, they might not be able to call the pet by name or might call it by the wrong name.
