Abstract
Objectives: Depression
is the most common affective disorder following stroke yet the
neuroanatomical model of poststroke depression
(PSD) remains unclear. This study examined the
association between PSD and cerebral microbleeds (CMBs) and hypothesized
that
CMBs in specific regions would be associated
with PSD.
Methods: Of the 4766
patients with first ever or recurrent acute ischemic stroke admitted to
the Acute Stroke Unit of the Prince of
Wales Hospital between June 2004 and October
2010, 229 met the entry criteria and formed the study sample. Patients
with a
Geriatric Depression Scale score of 7 or above
were classified as having PSD. The presence and location of CMBs were
evaluated
with magnetic resonance imaging.
Results: Compared to the non-PSD group, patients with PSD were more likely to have pontine CMBs (32.0% vs 18.2%; P = .019). The presence of pontine CMBs remained an independent predictor of PSD in the multivariate analysis, with an odds
ratio of 2.2 (P = .016).
Conclusion: The results suggest that pontine CMBs are associated with a higher risk of developing PSD.
