This Microwave Helmet Can Sense Strokes

Scientists in Sweden have invented a helmet that can identify whether a person has experienced a stroke, the BBC reports.

The headwear can further determine what kind of a stroke has occurred, allowing doctors to quickly diagnose and treat patients.

The helmet works by bouncing microwaves off a person’s brain and identifying whether there’s a bleed or a clot within it. Initial tests, involving 45 patients, proved successful. The helmet’s inventors now plan to roll the device out to ambulance teams and eventually put the technology in pillows as well.

At present, doctors treating stroke victims need to determine whether a clot or a leaking blood vessel caused the stroke. A CT scan is able to show this, but CT scanners aren’t available in every hospital and a scan can take time to set up. Delays in stroke treatment can be serious — brain tissue can begin to die if more than four hours passes between a stroke and treatment. The microwave helmet could reduce such delays, though researchers say more testing is required.

Some doctors have suggested that the helmet won’t completely replace other forms of diagnosis.

Dr. Shamim Quadir from the UK’s Stroke Association said that “while this research is at an early stage, microwave-based systems may become a portable, affordable, technology that could help rapidly identify the type of stroke a patient has had, and get them treated faster.”

15% of common strokes occur in adolescents and young adults

A team of researcher including an Indian origin has suggested that 15 percent of the most common type of strokes occur in adolescents and young adults, and more young people are showing risk factors for such strokes.

Co-author neurologist Jose Biller of Loyola University Medical Center said that the impact of strokes in this age group is devastating to the adolescent or young adult, their families and society.

About 85 percent of all strokes are ischemic, meaning they are caused by blockages that block blood flow to the brain. And more young people have risk factors for ischemic strokes.

Those risks include high blood pressure, diabetes, obesity, abnormal cholesterol levels, congenital heart disease and smoking.

Strokes in young people have a disproportionally large economic impact, because they can disable patients before their most productive years. And while coping with the shock of having a stroke, “younger survivors may be dealing with relationships, careers and raising children – issues that require additional awareness and resources,” the consensus report said.

Biller, one of the nation’s leading experts on stroke in young people, is second author of the consensus report. Biller is chair of the Department of Neurology of Loyola University Chicago Stritch School of Medicine. First author of the report is Aneesh Singhal, MD of Massachusetts General Hospital.

The study has been published in the journal Neurology.
