Mild depression in young adults with cerebral infarction at long-term follow-up: a population-based study

We sought to evaluate the prevalence of and risk factors for post-stroke depression (PSD) at long-term follow-up in young adults aged 15-49 years with first-ever cerebral infarction in a population-based study. Scores on Montgomery-Asberg Depression Rating Scale (MADRS) were obtained at follow-up (mean time 6.0 years after the stroke) and analysed in subgroups. MADRS scores were obtained in 196 of 209 surviving patients. PSD (MADRS>or=7) was detected in 56 patients (28.6%). None had severe PSD. Alcoholism (P=0.006), depressive symptoms any time before the index stroke (P=0.016), and severe neurological deficits on admission for the index stroke (P=0.043) were independently associated with PSD. PSD seems milder in young ischaemic stroke patients compared with older patients. Alcoholism, depression any time before the index stroke, and severity of neurological deficits on admission for the stroke increased the risk of developing PSD in the long run.
