Abstract

Object : Accumulating evidence suggests a greater number of subcortical hyperintensities in the brain with bipolar disorder. We studied the Clinical correlates of subcortical hyperintensities on magnetic resonance imaging in patients
with Bipolar Disorder :
Methods : Magnetic resonance images of the brain were obtained for 32 patients with bipolar disorder. The presence and location of hyperintensities were assessed. We compared clinical variables between with subcortical hyperintensities and
patients without them.
Results : Seven Patients(21.8%) had subcortical hyperintensities, but among 8 patients who were or older, 5 patients(625) had them, Age and age of onset of patients with subcotical hyperintensities were significantly older than patients without them. Psychotic symptoms were more frequent in patients with hyperintensities. Patients without hyperintesities had more familial loading.
Conclusion : Given the limitations of the study, our results should be seen as preliminary. This study, however, provides preliminary evidence supporting the notion that the onset, clinical feature and course of some bipolar disorders of late
onset may be determined by underlying subcortical abnormalities, with such abnormalities being the consequence of factors related to aging or neurodegeneration(such as impaired cerebral circulation) rather than genetic factors
which predispose to early-onset bipolar disorders.
