Perhaps you should try some spelling variations:
decrease striatal » disease striatal (Expand search), decrease survival (Expand search), decrease stigma (Expand search)
striatal problems » societal problems (Expand search), structural problems (Expand search), retrieval problems (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (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 _ decrease striatal problems ) OR ( decrease lesions decrease OR decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease striatal problems ) OR ( decrease lesions decrease OR decrease ))*.
