Companion animals can play a meaningful role in supporting emotional wellness for people living with dementia. Pets such as dogs and cats offer more than just companionship; they provide cognitive stimulation, emotional comfort, and social interaction that can help slow cognitive decline and reduce feelings of loneliness and anxiety.
Research shows that owning a dog or cat is linked to slower cognitive decline in older adults. Dog owners tend to retain sharper memory skills, while cat owners often experience a slower decline in verbal abilities. This may be because dogs and cats encourage mental engagement and social interaction, which are important for brain health. For example, walking a dog promotes physical activity and social contact, both of which benefit emotional and cognitive well-being. Cats may serve as a comforting presence that substitutes for social networks, helping to reduce isolation[1][3].
The emotional bond formed with pets can also lower stress and anxiety. Interaction with animals increases levels of brain chemicals like oxytocin and serotonin, which promote feelings of happiness and calm, while reducing cortisol, the stress hormone. This effect has been observed in various settings, including therapy animal visits that help reduce anxiety in children and adults alike. For people with dementia, the presence of a pet can provide a soothing routine and a sense of purpose, which supports emotional stability[5].
In addition to real animals, robotic or faux pets have been used in dementia care to similar effect. These pets can reduce stress and anxiety, offering comfort without the challenges of caring for a live animal. This approach is especially helpful in care environments where live pets may not be feasible[6].
While pets offer many benefits, it is important to consider individual circumstances. The type of pet, the level of attachment, and the person’s living situation can influence the emotional impact. For example, some studies suggest that less demanding pets like fish or rodents may also provide emotional benefits by fostering responsibility and empathy, though their impact on cognitive function appears less significant than that of dogs and cats[1][4].
Overall, companion animals can be a valuable source of emotional support for people with dementia, helping to improve mood, reduce loneliness, and maintain cognitive function through meaningful interaction and companionship.
