Depression relapse: why it comes back, and how to catch its signs and prevent itDepression can come back, but the risk of its return can be greatly reduced with a clear plan and follow-up

9What is depression relapse?

"I'd been fine for a year, and suddenly I found myself unable to get out of bed again." This moment is one of the hardest for someone who has recovered from depression, because it brings a feeling of failure and a fear that all the effort was wasted. The truth is that relapse is a known part of the nature of the illness, not evidence of weakness or failure.

Doctors sometimes distinguish between relapse, meaning the return of symptoms before recovery from the same episode is complete, and recurrence, meaning a new episode after a period of full recovery. The World Health Organization describes "recurrent depressive disorder" as a history of at least two depressive episodes. What matters in practice is that both call for the same attention and the same early intervention.

10Does depression come back after treatment? The numbers, plainly

In a systematic review published in Acta Psychiatrica Scandinavica in 2010, researchers found that recurrence of depression among patients of specialist psychiatric services is high:

These figures do not mean a return is inevitable; they reflect averages that include people who did not receive adequate follow-up. More importantly, the same review found that the number of previous episodes and mild residual symptoms were the strongest predictors of a return, while sex and social or economic status were not clearly linked to it. In other words, the strongest risk factors are ones you can work on with your doctor.

11Why does depression relapse happen?

• Stopping treatment early: feeling better leads many people to stop medication or sessions before the right time.
• Residual symptoms: incomplete improvement, such as ongoing sleep disturbance or losing some of the pleasure in things.
• Life stress: a loss, a financial crisis or a family conflict, especially when it comes without support.
• Substance use: alcohol, hashish and sedatives deepen low mood and interfere with treatment.
• Untreated co-occurring conditions: anxiety, chronic insomnia or physical illness.

If your depression occurs together with substance use, read depression and addiction, because preventing relapse here needs a plan that covers both together.

12What are the early signs of depression relapse?

Depression rarely returns all at once. The NICE guidelines state that part of relapse prevention is recognizing warning signs such as anxiety or poor sleep and unhelpful behaviors such as avoidance or rumination. This is a common sequence that many patients describe:

1. The start
   Sleep changes

   Difficulty sleeping, early waking, or sleeping more than usual.

2. After that
   Quiet withdrawal

   Declining invitations, dropping a hobby, answering fewer calls.

3. Then
   Familiar thoughts

   The harsh inner voice returns: "I'm a failure," "there's no point."

4. Over time
   Energy drops

   Simple tasks become heavy, and irritability rises.

5. If no one steps in
   The episode takes hold

   Pleasure fades, eating and concentration are disrupted, and life grinds to a halt.

Your own signs may differ, which is why it helps to go over these with your doctor: how did the previous episode begin? And what did your family notice first?

13Does staying on treatment prevent relapse?

In a systematic review published in The Lancet in 2003 that pooled 31 randomized trials, the average relapse rate among those whose antidepressant was stopped and replaced with a placebo was 41%, compared with 18% among those who stayed on it. That is, continuing reduced the likelihood of relapse by about 70%, and the effect lasted up to 36 months in some trials.

The NICE guidelines recommend discussing continuing medication for those at higher risk of relapse, or offering preventive psychotherapy to those who do not wish to. If you and your doctor decide to stop, it is done gradually; the symptoms of abrupt discontinuation differ from a return of the illness, as explained in our guide to antidepressant withdrawal. Do not start or stop any medication without a doctor.

14Mindfulness-based therapy to prevent a return

Mindfulness-based cognitive therapy (MBCT) is a group program designed specifically for people whose depression has recurred. In an analysis of data from 1,258 patients in randomized trials, published in JAMA Psychiatry in 2016, the risk of relapse over 60 weeks was lower in those who received it than in those who did not (hazard ratio 0.69), and the benefit was clearer in those with more residual symptoms.

NICE notes that group cognitive behavioral or mindfulness-based therapy for relapse prevention usually consists of 8 sessions over two to three months, with the possibility of additional sessions during the following year.

15How do you write an early-warning plan?

The NICE guidelines suggest that relapse-prevention components include reviewing what you learned in therapy, clear plans for what to do when each sign appears, and preparing for difficult occasions expected during the year. You can turn this into a simple sheet:

• My three early signs (for example: going to sleep after 2 a.m., canceling plans, snapping at the kids).
• What I do right away: return to my routine, tell someone I trust, and contact my doctor.
• What my family does: notices without suffocating monitoring, reminds me of my appointment, and does not say "you're back to this again?"
• Difficult situations expected this year, such as an anniversary of a death or a job change, and how I prepare for them.
• My doctor's number, the mental health support line 16328, and the ambulance (123) for any thought of self-harm.

16Follow-up at Eradah

At Eradah Hospital we treat relapse prevention as a core part of care: assessing residual symptoms, reviewing the medication and psychological plan, sessions that involve the family with the patient's consent, and regular follow-up through the follow-up program. If the relapse is severe or accompanied by substance use, residential treatment is available for men. The first consultation is free and confidential.
