Large-Vessel Occlusion Acute Ischemic Strokes are considered to be the most debilitating strokes, which occur due to the blockage of large cerebral arteries usually from blood clots or plaque buildup
New research published in the Journal of Stroke and Cerebrovascular Diseases confirms that strokes thought to happen in older adults are possible in the younger population (defined as 18-50 years old). Large-Vessel Occlusion Acute Ischemic Strokes (LVO-AIS) are considered to be the most debilitating strokes which occur due to blockage of large cerebral arteries usually from blood clots or plaque buildup. LVO-AIS is typically thought to occur in older adults given that older individuals are known to have risk factors for large-vessel occlusions. However, new research confirms that the younger population can have risk factors for these types of large-vessel occlusion strokes and have LVO-AIS at similar rates to older adults. Getting tested and seeing a primary care provider regularly are essential for stroke risk prevention.
The data shows that young adults suffer from large-vessel occlusion strokes just like older adults, and the majority have good outcomes if they arrive in a timely fashion and are treated with IV thrombolysis and thrombectomy.
The study looked at the young adult stroke population, while most studies have looked at older adults when looking back at patient populations. Cleveland Clinic looked at over 1,200 young adult patients from 2017 to 2021 in Ohio. Of that group, nearly 20% had large-vessel occlusion ischemic strokes, very similar strokes to older adults.
Half of the patients received no intervention, while 25% of those got no acute intervention because they arrived at the hospital too late. Had they arrived earlier, they could have been eligible for IV thrombolysis and possibly both IV thrombolysis and thrombectomy.
"This research helps us raise awareness about recognizing stroke symptoms in young adults early and that getting prompt treatment is paramount to achieve good outcomes,” said Abbas Kharal, M.D., a cerebrovascular neurologist with Cleveland Clinic's Cerebrovascular Center. “Further study is needed to identify barriers as to why young adults are delayed in seeking treatment for stroke, especially when they can have better outcomes than older adults if treated promptly. Many people still think of stroke as an event happening in the older population, but that is not what we are seeing in our practices. The younger population faces similar risk factors, which need to be addressed through routine clinical checkups."
Dr. Kharal said that young adult patients in our study experienced large-vessel occlusion strokes from blood clots or plaque formation, factors that are typically thought of in older adults, in addition to other causes including arterial diseases and cardiac issues. Ongoing studies at Cleveland Clinic are looking at more detailed causes of large-vessel occlusion ischemic stroke in young adults.
