People who are eligible for the study will exhibit severe psychomotor retardation, cognitive impairments, slow thinking and speech, profound anergia, etc. These people are likely to have the MDD illness. People with less severe depressions will more often be representitive of conditions other than MDD and that are more responsive to psychosocial influences.
