Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease spatial » decrease survival (Expand search), decrease striatal (Expand search), decrease asian (Expand search)
disease lesions » disease lessons (Expand search), diseases lessons (Expand search)
spatial effect » spatial effects (Expand search), spatial neglect (Expand search), spatial extent (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (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: "(( disease lesions decrease will decrease ) OR ( decrease can decrease spatial effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( disease lesions decrease will decrease ) OR ( decrease can decrease spatial effect ))*.
