Abstract:
There is increasing evidence for structural differences in the brains of patients with affective disorders. Recent magnetic resonance imaging (MRI) studies have reported focal signal hyperintensities in the deep white matter of bipolar patients. These previous reports had focused on adult patients with prior episodes of illness. In this case report, the authors discuss a young adolescent patient during her first episode of mania and the finding of subcortical focal signal hyperintensities on brain MRI. The etiology, pathophysiology, and clinical correlates of these lesions will be reviewed.
Insights
Brain imaging reveals subcortical white matter lesions in an adolescent during their first manic episode, suggesting these brain differences may occur early in bipolar disorder.
Area of Science:
- Neuroscience
- Psychiatry
- Radiology
Background:
- Affective disorders, such as bipolar disorder, are increasingly linked to structural brain differences.
- Previous magnetic resonance imaging (MRI) studies identified white matter lesions in adult bipolar patients.
Observation:
- This case report details a young adolescent experiencing their first manic episode.
- Brain MRI revealed subcortical focal signal hyperintensities in this patient.
Findings:
- The findings suggest that white matter lesions may be present even in the early stages of bipolar disorder, during the first manic episode in adolescents.
- This contrasts with prior research focusing on adult patients with established illness.
Implications:
- Further research is warranted to explore the etiology, pathophysiology, and clinical significance of these early-onset lesions.
- Understanding these early structural changes could inform diagnostic and therapeutic strategies for adolescent bipolar disorder.
