Investigating the link between cortical superficial siderosis and recurrent brain hemorrhage in patients with cerebral amyloid angiopathy

COrtical Superficial Siderosis and REcurrent Lobar Intracerebral Hemorrhage in Cerebral Amyloid Angiopathy.

Not applicable Interventional University Hospital, Toulouse · NCT03464344

This study is trying to see if having cortical superficial siderosis affects the chances of older patients with cerebral amyloid angiopathy having more brain bleeding episodes.

What this trial studies

This study aims to explore the relationship between cortical superficial siderosis (cSS) and the risk of recurrent symptomatic intracerebral hemorrhage (ICH) in patients diagnosed with cerebral amyloid angiopathy (CAA). Patients aged 55 and older who have experienced acute lobar ICH will be enrolled within 30 days of onset and will undergo brain MRI to assess the presence of cSS. The study will follow participants for 24 months, conducting neurological, neuropsychological, and MRI evaluations to compare the recurrence rates of symptomatic ICH between those with and without cSS.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 55 and older who have experienced a lobar ICH within the last 30 days and meet the criteria for probable or possible CAA.

Not a fit: Patients with secondary brain hemorrhages or those with contraindications to MRI will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at higher risk for recurrent brain hemorrhages, allowing for better management and preventive strategies.

How similar studies have performed: While the specific relationship between cSS and recurrent ICH in CAA is being investigated here, similar studies have shown promising results in understanding risk factors for recurrent hemorrhagic events.
