🧭 When to suspect

Perinatal mental illness covers a spectrum that any GP must hold in mind at every contact in pregnancy and the first year after birth. At the mild end sit the self-limiting maternity “blues”; in the middle, postnatal depression and the perinatal anxiety disorders (including obsessive–compulsive disorder and post-traumatic stress disorder, PTSD); and at the severe end, postpartum psychosis – a psychiatric emergency. The conditions are common and consistently under-recognised, and women may be reluctant to disclose for fear of stigma or of being judged as a mother.

The two clinical priorities are simple: screen actively and treat by severity, and never miss the emergencies – postpartum psychosis and maternal suicidality. At first contact and in the early postnatal period, screen for depression with the Whooley questions and for anxiety with the 2-item Generalized Anxiety Disorder scale (GAD-2), distinguishing transient “baby blues” from true pathology by the persistence and severity of symptoms.

Presentation	Typical onset	Key features	Action
Baby blues	Days 3–5, settling by ~day 10	Tearfulness, lability, irritability; mild and self-limiting	Reassurance and support; no treatment
Postnatal depression	Often within 3 months (any time in year 1)	Persistent low mood, anhedonia, fatigue, guilt, poor sleep	Assess severity; self-help / CBT ± SSRI
Anxiety / OCD / PTSD	Pregnancy or postnatal	Excessive worry, intrusive thoughts, birth-trauma flashbacks	Psychological therapy ± SSRI
Postpartum psychosis	Rapid, usually first 2 weeks	Mania or depression with psychosis, confusion, delusions, hallucinations	Emergency → same-day specialist assessment

Raise your index of suspicion in women with a personal or family history of mental illness – particularly previous postnatal depression, bipolar disorder, or previous postpartum psychosis – and in those facing poor social support, relationship difficulties, domestic abuse, or substance misuse. Postpartum psychosis occurs in about 1–2 in 1000 births and is strongly linked to bipolar disorder and to severe perinatal mental illness in a first-degree relative.
