Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decreased brain » decreases brain (Expand search), increased brain (Expand search), decreased in (Expand search)
brain decrease » brain decreases (Expand search), brazil decrease (Expand search), strain decrease (Expand search)
std processing » seed processing (Expand search), and processing (Expand search), end processing (Expand search)
decrease std » decrease sod (Expand search), decrease and (Expand search), decrease at (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreased brain decrease std processing ) OR ( decrease NOT decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased brain decrease std processing ) OR ( decrease NOT decrease lesions decrease ))*.
