Relapse: Early Warning Signs

Early warning signs are changes that sometimes precede a person’s relapse. They may include disrupted sleep, increased anxiety, social withdrawal, reduced self-care or a return of familiar unusual experiences. The most useful signs are often those identified from the individual’s own previous episodes rather than a generic checklist.

Relapse means a significant return or worsening of illness symptoms after a period of improvement. Definitions vary across clinical services and research studies. A brief fluctuation is not automatically a relapse, and changes should be interpreted against the person’s usual pattern, functioning and circumstances rather than one isolated sign.

These signs are not perfectly predictive and may have other explanations. Monitoring should therefore be proportionate and agreed with the person. A simple record of sleep, stress and functioning can support discussion without turning ordinary life into constant surveillance. Plans can specify which changes call for routine contact and which require urgent help. Family or trusted supporters may contribute when appropriate. The purpose is early assistance, not proving that the person is becoming ill or interpreting every disagreement as evidence of deterioration.

An individual warning-sign plan works best when it includes an agreed action. Noticing sleep change is useful if the person knows whom to contact and what support may follow. The plan should also recognise false alarms. This preserves ordinary autonomy and reduces anxiety about monitoring, while keeping a clear route to assessment when a concerning pattern develops.
