Women and stroke: Why pregnancy and hormonal factors need closer attention, and how treatment and prevention work

New Delhi: Stroke is a major cause of death and long-term disability in women worldwide. Although the underlying mechanisms of stroke are similar in both sexes, women have unique risk factors, clinical considerations, and challenges in prevention and management.

Sex-specific risk factors

In addition to conventional risk factors such as hypertension, diabetes mellitus, dyslipidaemia, smoking, and atrial fibrillation, women have several sex-specific risk factors. These include pregnancy, the postpartum period, preeclampsia, eclampsia, oestrogen-containing oral contraceptives, and certain forms of menopausal hormone therapy. Migraine with aura, particularly when associated with smoking or oestrogen-containing contraceptives, is an important consideration in young women. Hypertensive disorders of pregnancy are also associated with increased long-term cardiovascular and cerebrovascular risk.

Women commonly present with classical stroke symptoms, including unilateral weakness, facial asymmetry, speech disturbances, visual loss, and gait imbalance. However, nonspecific symptoms such as confusion, nausea, generalised weakness, and altered consciousness may also occur, potentially complicating early recognition. Prompt identification and emergency evaluation are essential to minimise neurological disability.

Stroke during pregnancy

Pregnancy and the postpartum period are associated with an increased risk of several cerebrovascular disorders, including arterial ischaemic stroke, cerebral venous sinus thrombosis (CVST), intracerebral haemorrhage, reversible cerebral vasoconstriction syndrome (RCVS), and posterior reversible encephalopathy syndrome (PRES). Severe headache, seizures, visual disturbances, or focal neurological deficits in pregnant or postpartum women warrant urgent investigation.

Management and prevention

Acute stroke management follows the same fundamental principles in women and men. Rapid neuroimaging, timely reperfusion therapy in eligible patients, and mechanism-specific secondary prevention are crucial. Pregnancy and the postpartum state require individualised assessment but should not automatically preclude potentially life-saving treatment. Long-term prevention includes optimal blood pressure control, diabetes management, lipid reduction, smoking cessation, and appropriate antiplatelet or anticoagulant therapy according to stroke aetiology.

Stroke in women requires a life-course approach to prevention, recognising the influence of reproductive factors, pregnancy-related complications, and hormonal exposures alongside conventional vascular risks. Greater awareness, early recognition, equitable access to stroke services, and individualised preventive strategies are essential to improving outcomes in women.
