There are no effective treatments for neurodegenerative disorders, practically all currently available treatments are symptomatic. This is partially related to the poor understanding of the pathogenesis of these diseases, and partly due to the lack of good animal models. Cholinesterase or secretase inhibitor therapy or immunotherapy has been attempted in dogs with CDD, with overlapping results to human AD trials. The neuroprotective effects of cognitive enrichment, alongside with antioxidant-rich diet, show benefits in managing the disease progression and severity in both humans and dogs. Similar results with various drugs do suggest that dogs are useful model to study both pathogenesis and novel treatments for AD in the future.
