How cats with dementia could help crack the Alzheimer’s puzzle

Cats can naturally develop dementia with brain changes strikingly similar to Alzheimer’s disease in humans, including toxic amyloid-beta buildup and loss of synapses. A new study shows these similarities could make cats valuable natural models for research, potentially leading to treatments that benefit both species. The research also revealed that brain support cells may contribute to synapse loss, and findings could help owners recognize and manage dementia symptoms in aging pets.
