The Lazarus Effect


By Athos Patsalides, MD
Associate Professor of Radiology in Neurological Surgery

Vascular specialists, who work with patients experiencing conditions and disorders of the blood vessels, often talk of the “Lazarus effect,” a phenomenon in which a patient revives after coming to the brink of death, as happens in stroke or heart failure. Until recently I’d never witnessed it personally. Then, a few months ago, I treated a patient whose blood flow in the left half of the brain was completely blocked and who was in some sense of the word dead (or at least perilously close to it) when I saw him suddenly come back – at my hands.

The Rush of Finding a New Treatment


By Dr. Jared Knopman
Assistant Professor of Neurosurgery

One of the most exciting things in neurosurgery – in fact, in medicine in general – is discovering a genuinely different approach to treating a condition. It’s extremely gratifying to find a better way to treat your patients, especially when it means sparing them open surgery and offering a minimally invasive alternative. When that finding also happens to completely upend traditional thinking about a common condition, it’s quite remarkable indeed.

Facing the Neurosurgical Challenge of Tanzania


By Andreas Leidinger, M.D.
Global Neurosurgery Fellow
Muhimbili Orthopaedic Institute

Dar es Salaam, Tanzania

 It is hard to explain when my passion for Africa was born. I trained as a neurosurgeon at a beautiful hospital in Barcelona, where the standards of “western” medicine is upheld and everything was always available for my patients. During my training, I had the eye-opening opportunity to collaborate with several projects on improving health care in Africa. Initially I experienced culture shock; however, after learning to embrace a new reality, I began to genuinely relate to the local people. I felt the need to make personal compromises and to seriously get involved.

Falling in Love With Science… and Boxing


By Roberta Marongiu, PhD
Assistant Professor of Neuroscience
Molecular Neurosurgery Laboratory, Neurological Surgery
Feil Family Brain and Mind Institute

I fell in love with science when I was a teenager, thanks to a wonderful teacher I had in high school. She taught genetics, chemistry, and astronomy, and she recognized something in me that she encouraged me to pursue. Up until then I thought I would have a career in business, but thanks to her I changed my mind and chose a career in science instead.

Concussion 101: Children Versus Adults


By Kenneth Perrine, PhD

As anyone who’s ever been a parent (or teacher, or pediatrician, or coach) can tell you, children are not just little adults – they are fundamentally different creatures in terms of emotional maturity and mental development. As any doctor can tell you, children are also very different from adults when it comes to risk factors, behavioral influences, and healing.

Perceptions of Creative Genius: Impetus for Innovation and Collaboration


Caitlin Hoffman, MD

An Antiguan artist under-appreciated and misunderstood during his lifetime has found an audience at last, and what his work suggests about the mind is fascinating.

An Imperfect Gauge of Concussion


Philip E. Stieg, PhD, MD
Neurosurgeon-in-Chief

The brain, our marvelously complex and mysterious command center, is simply too intricate and nuanced for any one test to pick up every sign of injury.

Improving on the Delivery of Stroke Care


Jared Knopman, MD

Over the past couple of years there has been an explosion of new data proving the benefits of two things: early intervention for stroke, and mechanical embolectomy using endovascular techniques.  We have long known that “time is brain,” but we finally have proof that the sooner stroke patients are evaluated by a team of physicians at a Comprehensive Stroke Center the better.
