Perhaps you should try some spelling variations:
depressed faster » depressed older (Expand search), depressed aged (Expand search), depressed area (Expand search)
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
faster decrease » rate decrease (Expand search)
decrease of » decrease in (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 OR decrease of process ) OR ( decrease during depressed faster decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease OR decrease of process ) OR ( decrease during depressed faster decrease ))*.
