Talvez deva tentar algumas variações de ortografia:
during depressed » during depressive (Expandir a busca), during repressive (Expandir a busca), feeling depressed (Expandir a busca)
decrease during » increase during (Expandir a busca), increases during (Expandir a busca), increased during (Expandir a busca)
decrease pain » decreases pain (Expandir a busca), decrease in (Expandir a busca), decreased brain (Expandir a busca)
