Recurrent depressive disorder (ICD-10 code F33) is characterized by the occurrence of repeated episodes of depression separated by periods of relative recovery. For this diagnosis to apply, there must have been at least two depressive episodes, each lasting at least two weeks, separated by a symptom-free interval of several months without significant mood disturbance.
Unlike an isolated episode (F32), a diagnosis of F33 involves a recurrent pattern that increases the risk of new episodes. The recurrence rate is high: 40% in the first two years following the first episode, and about 50% at 5 years. Each previous episode increases the risk of subsequent episodes.
Episodes classified under F33 are categorized according to their current severity: mild (F33.0), moderate (F33.1), severe without psychotic symptoms (F33.2), severe with psychotic symptoms (F33.3), and in remission (F33.4). The pattern of presentation may vary: some patients have seasonal episodes, others experience episodes triggered by life stressors, and in others, episodes appear to arise endogenously.
Psychological treatment of major depression Recurrent depression has two distinct phases: the acute phase, which focuses on reducing the symptoms of the current episode, and the maintenance phase, which aims to prevent future relapses. At MadridPsicoterapia, located at Calle Santa Engracia 141 in Madrid (Chamberí), we design treatment plans that address both phases, using tools for emotional regulation, cognitive restructuring, and behavioral activation. Mindfulness-based therapy (MBCT) has also been shown to be specifically effective in preventing relapses in patients who have had three or more previous episodes.
Frequently Asked Questions
We know that many questions may arise before starting therapy. Here, we answer the most common questions we receive from people who contact our clinic.
The recurrence of depression is due to a combination of biological, psychological, and contextual factors. Biologically, certain neurobiological patterns of vulnerability predispose individuals to new episodes. Psychologically, the negative cognitive schemas (beliefs about oneself, the world, and the future) underlying depression can be reactivated by minor stressors with each previous episode. This is known as the cognitive scarring hypothesis. In addition, environmental factors such as work-related stress, relationship conflicts, or life changes can act as triggers. Psychotherapy addresses all these levels to reduce vulnerability to recurrence.
The duration of pharmacological treatment for recurrent depression is determined by the psychiatrist, based on the number of previous episodes, their severity, and the response to treatment. Clinical guidelines generally recommend continuing antidepressant medication for at least 6–12 months after an episode has remitted, and for patients with three or more previous episodes, indefinite maintenance treatment may be recommended. At MadridPsicoterapia, we coordinate with psychiatry to ensure that psychological and pharmacological treatments work in tandem.
Yes. Several lifestyle factors have a proven impact on relapse prevention: regular physical exercise (30 minutes, 3–5 times a week) reduces depressive symptoms and acts as a protective factor; sleep hygiene is essential, as sleep disorders are both a symptom and a risk factor for new episodes; behavioral activation—maintaining a schedule of enjoyable and social activities—protects against depression. In addition, mindfulness practice, stress management, and a balanced diet are part of the recommendations we provide at MadridPsicoterapia as part of the maintenance plan.
