1. The prevalence of post-stroke apathy (PSA) at 3 months was 24.7% among 267 stroke survivors.
2. Risk factors associated with PSA were older age, male sex, history of hyperlipidaemia, depressive symptoms, a lower level of cognitive function, and functional disability. A pontine acute infarct on magnetic resonance images was an independent predictor of PSA at 3 months.
3. PSA persisted in 51.1% of 47 stroke patients at 9 months and 41.7% of 12 patients at 15 months.
4. The onset of PSA can be delayed. Among 201 non-PSA patients at 3 months, 21 developed PSA at the later stage of rehabilitation (9 or 15 months).
5. The psychological burden of PSA should not be neglected. Early identification and treatment are essential.
