Cognitive Dysfunction in Cats: Update on Neuropathological and Behavioural Changes Plus Clinical Management.

Area of Science:

• Veterinary Neurology
• Comparative Pathology
• Animal Behavior

Background:

• Cognitive Dysfunction Syndrome (CDS) in cats presents behavioral changes similar to human Alzheimer's disease (AD).
• Cats exhibit VISHDAAL signs: Vocalisation, Interaction changes, Sleep-wake cycle alterations, House-soiling, Disorientation, Activity changes, Anxiety, and Learning/memory deficits.
• Neuropathologies like beta-amyloid and tau deposits are observed in feline CDS brains, mirroring human dementia.

Purpose of the Study:

• To review the literature on feline CDS, covering causes, neuropathology, clinical signs, diagnosis, and management.
• To highlight the domestic cat as a natural model for studying human dementia.
• To emphasize prompt diagnosis and effective management strategies for improving feline health and welfare.

Main Methods:

• Literature review of scientific articles on feline Cognitive Dysfunction Syndrome.
• Analysis of research on neuropathological similarities between feline CDS and human Alzheimer's disease.
• Compilation of current diagnostic and therapeutic approaches for CDS in cats.

Main Results:

• Feline CDS shares significant clinical and neuropathological parallels with human AD.
• A range of management options exist, including environmental enrichment, dietary supplements, specific diets, and medications.
• Prompt diagnosis is crucial for effective intervention and improved patient outcomes.

Conclusions:

• The domestic cat serves as a valuable natural model for human dementia research.
• Comprehensive understanding and management of CDS are essential for enhancing the quality of life for affected cats.
• Further research into CDS pathogenesis and treatment can benefit both feline and human health.
