The voices in my head

To all appearances, Eleanor Longden was just like every other student, heading to college full of promise and without a care in the world. That was until the voices in her head started talking. Initially innocuous, these internal narrators became increasingly antagonistic and dictatorial, turning her life into a living nightmare. Diagnosed with schizophrenia,

A roadmap to end aging

Cambridge researcher Aubrey de Grey argues that aging is merely a disease -- and a curable one at that. Humans age in seven basic ways, he says, all of which can be averted.

Battling bad science

Every day there are news reports of new health advice, but how can you know if they're right? Doctor and epidemiologist Ben Goldacre shows us, at high speed, the ways evidence can be distorted, from the blindingly obvious nutrition claims to the very subtle tricks of the pharmaceutical industry.

Is the obesity crisis hiding a bigger problem?

As a young surgeon, Peter Attia felt contempt for a patient with diabetes. She was overweight, he thought, and thus responsible for the fact that she needed a foot amputation. But years later, Attia received an unpleasant medical surprise that led him to wonder: is our understanding of diabetes right? Could the precursors to diabetes cause obesity, and not the

What happens when you have a disease doctors can't diagnose

Five years ago, TED Fellow Jennifer Brea became progressively ill with myalgic encephalomyelitis, commonly known as chronic fatigue syndrome, a debilitating illness that severely impairs normal activities and on bad days makes even the rustling of bed sheets unbearable. In this poignant talk, Brea describes the obstacles she's encountered in seeking treatment for her

A doctor's touch

Modern medicine is in danger of losing a powerful, old-fashioned tool: human touch. Physician and writer Abraham Verghese describes our strange new world where patients are merely data points, and calls for a return to the traditional one-on-one physical exam.

How do we heal medicine?

Our medical systems are broken. Doctors are capable of extraordinary (and expensive) treatments, but they are losing their core focus: actually treating people. Doctor and writer Atul Gawande suggests we take a step back and look at new ways to do medicine -- with fewer cowboys and more pit crews.

Her research with at-risk populations -- from junkies in prison to sex workers on the street in Cambodia -- demonstrates the sometimes counter-

The US needs paid family leave — for the sake of its future

We need women to work, and we need working women to have babies. So why is America one of the only countries in the world that offers no national paid leave to new working mothers? In this incisive talk, Jessica Shortall makes the impassioned case that the reality of new working motherhood in America is both hidden and horrible: millions of women, every year, are

Could tissue engineering mean personalized medicine?

Each of our bodies is utterly unique, which is a lovely thought until it comes to treating an illness -- when every body reacts differently, often unpredictably, to standard treatment. Tissue engineer Nina Tandon talks about a possible solution: Using pluripotent stem cells to make personalized models of organs on which to test new drugs and treatments, and storing

A temporary tattoo that brings hospital care to the home

The poignant story of parents facing their fears -- and how they turned

What if our healthcare system kept us healthy?

Rebecca Onie asks audacious questions: What if waiting rooms were a place to improve daily health care? What if doctors could prescribe food, housing and heat in the winter? At TEDMED she describes Health Leads, an organization that does just that -- and does it by building a volunteer base as elite and dedicated as a college sports team.

What makes us get sick? Look upstream.

Rishi Manchanda has worked as a doctor in South Central Los Angeles for a decade, where he’s come to realize: His job isn’t just about treating a patient’s symptoms, but about getting to the root cause of what is making them ill—the “upstream" factors like a poor diet, a stressful job, a lack of fresh air. It’s a powerful call for doctors to pay attention to a patient

The world's killer diet

See how it works, as a paralyzed rat becomes able to

Why genetic research must be more diverse

Ninety-six percent of genome studies are based on people of European descent. The rest of the world is virtually unrepresented — and this is dangerous, says geneticist and TED Fellow Keolu Fox, because we react to drugs differently based on our genetic makeup. Fox is working to democratize genome sequencing, specifically by advocating for indigenous populations to get
