How does brain atrophy lead to sleep impairment?
How does brain atrophy lead to sleep impairments?
I am writing a medical paper. And this is a problem that has troubled me every times when it concerns the plural or singular forms of some relatively abstract words in my article.
The question is: since the noun "impairment" can be uncountable or countable, is to choose either is depended on the meaning I want to present in certain context?
- If I want to use it as a mass concept, then I should use (1).
- If I want to explain several sleep impairments following, then I should use (2).
