in major depressive disorder what percentage of patients will suffer a recurrent episode
Major depressive disorder Studies have shown that 80% of those suffering from their first major depressive episode will suffer from at least 1 more during their life,[224] with a lifetime average of 4 episodes.[225] Other general population studies indicate that around half those who have an episode recover (whether treated or not) and remain well, while the other half will have at least one more, and around 15% of those experience chronic recurrence.[226] Studies recruiting from selective inpatient sources suggest lower recovery and higher chronicity, while studies of mostly outpatients show that nearly all recover, with a median episode duration of 11 months. Around 90% of those with severe or psychotic depression, most of whom also meet criteria for other mental disorders, experience recurrence.[227][228]
