Signs include disorientation, sleep reversal, house soiling, and reduced social interaction
The DISHAA scale assesses CDS severity across six behavioural domains
Selegiline and dietary supplements including antioxidants may slow progression
Environmental modifications including nightlights and routine reduce CDS-related anxiety
