Neuroscience services and specialty centers

Advanced neurovascular treatment

We diagnose and treat brain conditions such as aneurysms, arteriovenous malformations (AVM) and strokes. We use state-of-the-art treatments to save your life and preserve your neurological functions.

Comprehensive Stroke Center and Primary Stroke Center

Comprehensive Stroke Center gold seal

In October 2012, Lehigh Valley Hospital became the first stroke center in Pennsylvania, and one of the first in the United States, to earn advanced certification as a Comprehensive Stroke Center by the Joint Commission. This Gold Seal means we offer the highest standard of care for stroke; it recognizes our significant resources in staff and advanced training needed to treat patients with complex strokes in our Neuroscience Intensive Care Unit (NSICU).

In 2004, Lehigh Valley Hospital-Cedar Crest was the first hospital in the region to be designated a Primary Stroke Center. Lehigh Valley Hospital-Muhlenberg received that same certification in 2006. A Primary Stroke Center is a hospital that has developed special procedures to rapidly diagnose and treat a stroke.
