Biography

Dr. Walid Albanna grew up in Gaza City, Palestine, and received a high school diploma (97%) from Khalil Al-Wazir School in Gaza. Dr. Walid graduated from the Faculty of Medicine at the University of Cologne, Germany (2009).

Dr. Walid is a consultant neurosurgeon at the University Hospital RWTH Aachen, Germany (Neurosurgery and Spinal Surgery). Dr. Walid is the Star of Science 2018. He developed a smart goggle that can predict and detect stroke after the subarachnoid Hemorrhage (kind of brain hemorrhage). In his rigorous studies in neurosurgery, Dr. Walid demonstrated that stroke can be easily predicted. His scientific research has been published in the largest scientific journals and he has been awarded with DGNI Award in 2017 as the best scientific research in Germany.

Dr. Walid leads a high-precision database of patients after brain hemorrhage (Subarachnoid Hemorrhage, SAH). Dr. Walid has been able to gain scientific expertise from the University of Minnesota in the United States of America (Department of Neuroscience) and the University of California Davis (EyePod Laboratory) in the United States.

Synopsis

The Eye as a Window to the Brain

Patients with aneurysmal subarachnoid hemorrhage (ASAH) face persistently high overall morbidity and mortality. Cerebral vessel constriction (vasospasm) after ASAH occurs in about 2/3 of patients, and in about half of the cases, they develop ischemic strokes. Delayed cerebral ischemia (DCI), defined as clinical worsening, or new functional deficit (oxygenation crisis or metabolic disturbance), has been shown to contribute significantly the cerebral infarction, which in turn influences the outcome. Timely detection of cerebral vasospasm and DCI is essential to improve outcome, but can pose a diagnostic challenge, particularly in sedated patients where the neurological examination is difficult to perform. Changes in vessel caliber and functionality of autoregulation and neurovascular coupling have been shown to be predictive of clinical outcome, and continuous or reproducible assessment of these parameters could potentially be used to optimize further established treatment efforts and improve outcome. For this patient subgroup, advanced monitoring techniques are available, but for the most part are either non-invasive and momentary or invasive and continuous. Ideally, these modalities could be supplemented with an alternative, non-invasive and continuous or repeatable monitoring approach.
The retinal vasculature shares an embryological origin with strictly intracranial vessels and lends itself as a new tool for cerebrovascular monitoring. With the idea of electronic spectacles, a variety of relevant alterations can be detected (vasospasm after aneurysmal subarachnoid hemorrhage, stroke, arterial hypertension, Diabetes Mellitus and many other diseases). After detection of altered neuronal function, a confirmatory invasive testing can be initiated and rescue neurosurgical and/or endovascular therapies can be performed earlier to improve outcome.
Dr. Albanna has developed a portable device that detect brainchanges after Scanning of the retina and won the first place as star of science 2018.
