Perhaps you should try some spelling variations:
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease wake » decrease age (Expand search), decreases water (Expand search), decreased base (Expand search)
wake patterns » intake patterns (Expand search), usage patterns (Expand search), trade patterns (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any 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: "(( decrease _ decrease akt decrease ) OR ( decrease during decrease wake patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease akt decrease ) OR ( decrease during decrease wake patterns ))*.
