Perhaps you should try some spelling variations:
lesions increase » lesions decrease (Expand search), neurons increases (Expand search), levels increase (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
increase walking » increase during (Expand search), increase skin (Expand search)
walking objects » talking objects (Expand search), walking subjects (Expand search), falling objects (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (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: "(( decrease will decrease NOT decrease ) OR ( decrease lesions increase walking objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease will decrease NOT decrease ) OR ( decrease lesions increase walking objects ))*.
