Feline Dementia Offers Insights into Alzheimer's
Recent research has revealed striking similarities between dementia in cats and Alzheimer's disease in humans, offering new hope for breakthroughs in treatment. Scientists at the University of Edinburgh conducted post-mortem brain examinations on 25 cats that had shown symptoms of dementia, such as confusion, disrupted sleep patterns, and increased vocalisation.
Key Findings
The study uncovered a build-up of amyloid-beta, a toxic protein that is a hallmark of Alzheimer's disease. This discovery positions cats as a "perfect natural model" for studying Alzheimer's, potentially paving the way for new treatments for both humans and pets.
How Cats Could Help Alzheimer's Research
Microscopy images of older cats revealed amyloid-beta accumulation within synapses, the junctions between brain cells. Synapses are essential for transmitting messages between brain cells, and their loss leads to reduced memory and cognitive abilities in humans with Alzheimer's. Researchers believe that studying these natural brain changes in cats could provide a more accurate model of the disease compared to genetically-modified rodents, which do not naturally develop dementia.

The study also found evidence of synaptic pruning, a process where brain support cells like astrocytes and microglia engulf affected synapses. While this process is crucial during brain development, it contributes to dementia in older cats. Experts believe these findings could lead to better understanding and management of feline dementia, benefiting both cats and their owners.
What This Means for Pet Owners
Feline dementia is distressing for both cats and their caregivers. Studies like this aim to uncover effective treatments, improving the quality of life for ageing cats and offering insights into Alzheimer's care for humans. As Dr. Danielle Gunn-Moore, a feline medicine expert, stated: "This research is wonderful for cats, their owners, and people with Alzheimer's disease."
Ethical Considerations
The study was conducted respectfully, using the brains of cats that had already passed away. Animal rights groups have praised the non-invasive nature of the research but remain opposed to experiments on live animals.
Published in the European Journal of Neuroscience, the study was funded by Wellcome and the UK Dementia Research Institute, with contributions from scientists in Edinburgh, California, and Scottish Brain Sciences.
