How it's used

While often used in medical contexts to describe physical or mental decline, this term is also frequently applied to skills or habits that have become rusty due to lack of practice. It carries a slightly formal or clinical tone compared to more casual ways of saying something has gotten worse. When referring specifically to cognitive decline in the elderly, it is the standard component in terms like 腦退化症.

Examples

As people age, it is inevitable that bodily functions will deteriorate.

Common phrases

functional deterioration

Common mistake

Avoid using this to describe inanimate objects breaking down or losing quality, as it specifically implies a biological or functional regression of a living system. For mechanical items or general quality, use 變差 or 損壞 instead.
