Understanding CDS
Cognitive dysfunction syndrome (CDS) is a progressive, age-associated condition affecting brain function. Dogs and cats can both be affected.
What it can change
CDS can affect memory, learning, awareness, sleep, social interaction and emotional responses. It shares features with dementia in people, but is not identical to human Alzheimer’s disease.
Changes may develop gradually. The signs, rate of progression and response to treatment vary between individuals. CDS is not an inevitable part of ageing.
There is no cure, but management may improve daily function, comfort and quality of life. A plan can address the individual animal’s needs and be adjusted over time.
How veterinarians assess it
Your observations and the timeline of changes are central to the assessment. Your veterinarian may consider:
- A physical examination and pain assessment.
- Assessment of hearing and vision.
- Blood and urine tests to look for other health problems.
- Blood pressure measurement where appropriate.
- Further investigations when the history or examination indicates a need.
- Questionnaires reviewed by a veterinarian and repeated assessment over time.
Advanced imaging may be helpful in some cases. It is not mandatory for every animal.
No single routine test confirms CDS. This website does not assess questionnaire responses or diagnose your animal.
