[Magnetic resonance in patients with affective illness--relationship with silent cerebral infarction]
1Department of Psychiatry and Neurosciences, Hiroshima University School of Medicine.
Abstract:
We reviewed the relationship between affective disorder and magnetic resonance imaging (MRI). There are many reports that elderly patients with depression had increased small deep white matter lesions than the normal control. We examined silent cerebral infarction (SCI) in patients with presenile and senile major depression. Our findings suggest that half of presenile-onset major depression and the majority of senile-onset major depression might be organic depression related to SCI. Because patients with depressive states with SCI are at high risk of occurrence of stroke, we designated this condition "pre-stroke depression". It is important to begin therapy for cerebrovascular disease at this time.
Insights
Major depression in older adults may be linked to silent cerebral infarction (SCI), a brain abnormality. Identifying this "pre-stroke depression" is crucial for preventing strokes and initiating timely cerebrovascular disease therapy.
Area of Science:
- Neurology
- Psychiatry
- Radiology
Context:
- Growing evidence links affective disorders with neuroimaging findings.
- Elderly patients with depression often exhibit increased small deep white matter lesions compared to controls.
Purpose:
- To investigate the association between silent cerebral infarction (SCI) and major depression in presenile and senile populations.
- To determine the potential organic basis of depression in these age groups.
Summary:
- This study examined silent cerebral infarction (SCI) in patients with presenile and senile major depression using magnetic resonance imaging (MRI).
- Findings indicate that SCI may underlie a significant portion of major depression cases in older adults, particularly senile-onset depression.
- The researchers propose the term "pre-stroke depression" for depressive states associated with SCI due to heightened stroke risk.
Impact:
- Highlights the potential organic basis of depression in elderly individuals.
- Emphasizes the importance of identifying "pre-stroke depression" for early intervention.
- Suggests proactive management of cerebrovascular disease in patients with depression and SCI to mitigate stroke risk.
