Abstract:
Iron has been shown to accumulate in deep gray matter structures in many forms of multiple sclerosis (MS), but detecting its presence early in the disease course (e.g., clinically isolated syndrome [CIS]) has been less clear. Here, we review a recent study where MRI scanning at 7 T together with susceptibility mapping was performed to assess iron deposition in CIS and control subjects. Susceptibility indicative of iron deposition was found to be increased in the globus pallidus, caudate, putamen and pulvinar of CIS patients compared with controls. The findings suggest that iron deposition is a pathological change that occurs early in the development of MS. Identifying the mechanisms of iron accumulation and determining whether iron promotes pathogenesis in MS are important areas of future research.
Insights
Iron accumulation in the brain is detectable early in multiple sclerosis (MS), even in clinically isolated syndrome (CIS). This early iron deposition in deep gray matter suggests it
Area of Science:
- Neuroimaging
- Neurology
- Biochemistry
Background:
- Iron accumulation in deep gray matter is observed in multiple sclerosis (MS).
- Early detection of iron deposition in clinically isolated syndrome (CIS), an early MS stage, remains unclear.
Purpose of the Study:
- To assess early iron deposition in the brain of patients with CIS.
- To investigate the presence of iron accumulation in deep gray matter structures during the early stages of MS.
Main Methods:
- Utilized 7 Tesla (7 T) MRI scanning.
- Employed susceptibility mapping techniques.
- Compared iron deposition in CIS patients versus healthy controls.
Main Results:
- Increased susceptibility, indicative of iron deposition, was found in the globus pallidus, caudate, putamen, and pulvinar.
- These findings were observed in CIS patients compared to control subjects.
Conclusions:
- Iron deposition is an early pathological change in the development of multiple sclerosis.
- Further research is needed to understand the mechanisms and role of iron accumulation in MS pathogenesis.
