Siddharth Mehta, MD, has spent years caring for patients at some of the most urgent and frightening moments of their lives. As a stroke neurologist focused on vascular care, he often meets people in crisis, when the ability to speak, move, or function normally can change in an instant.

Over time, that work has led him to think just as deeply about what happens before a medical emergency begins. “The brain has always fascinated me,” Mehta says. “It’s essentially the computer of the human body—it controls how we move, speak, think, remember, and interact with the world.”

Every Minute Matters

During his medical training, Mehta became especially interested in the blood vessels of the brain, what he calls “brain plumbing.” The idea that doctors could guide tiny catheters through the body’s blood vessels into the brain to remove a clot or treat an aneurysm without open brain surgery felt remarkable to him. “I knew pretty quickly that this was what I wanted to do,” he says.

What Mehta values most about his work is the chance to care for patients across the full arc of a stroke. He may first see someone in the emergency room unable to speak or move one side of their body. From there, he can perform a procedure to restore blood flow, help manage the critical phase of recovery, and hopefully see that same person return to the office in due time. “That’s incredibly gratifying,” he says. “I feel very blessed to be able to do that.”

At the same time, years of treating stroke patients have changed the way he thinks. “What if we could prevent that person from ever having the stroke in the first place?” he wonders. “That’s increasingly where my passion lies.”

When talking about stroke awareness, Mehta has one main message: Time is brain. “In a major ischemic stroke, roughly 2 million neurons can be lost for every minute treatment is delayed,” he says. “So do not wait. If someone suddenly develops facial drooping, one-sided weakness or numbness, difficulty speaking, vision loss, or severe imbalance, call 911 right away.”

Back to Basics

After treating thousands of patients with vascular disease, Mehta says he has become even more aware of how often risk builds quietly over time. High blood pressure, diabetes, high cholesterol, excess weight, poor diet, smoking, lack of physical activity, and poor sleep may not feel urgent in the moment, but their effects accumulate. “A significant amount of vascular disease is preventable or modifiable,” he says. “That realization changed how I look at my own health. Why wait until disease develops to start taking care of your blood vessels?”

That thinking eventually led him to develop what he calls the five pillars of vascular health: sleep, exercise, vegetable-rich nutrition, hydration, and purpose. “I wanted it to be simple,” he says. “People are overwhelmed with health advice. There are diets, supplements, fitness programs, and complicated rules everywhere. I don’t think most people need another complicated health program. We need to get back to basics. You don’t have to live perfectly. You just have to consistently do the basic things that human beings need to stay healthy.”

According to Mehta, one of these five pillars is regularly underestimated by people—sleep. However, it is essential to one’s well-being. “I’ve come to view sleep as non-negotiable,” he says.

A Broader Mission

The desire to make prevention more accessible is what inspired SEVHA, which stands for Stroke Education and Vascular Health Awareness. Mehta says the name is also rooted in the Sanskrit word seva, meaning selfless service without expectation of personal reward. “I feel incredibly blessed to be a physician,” he says. “But eventually I started thinking: How can I help more people than the patients who reach my hospital? Instead of only treating disease, I want to help prevent it.”

Mehta’s hope is to reach people before they ever become patients. That includes working with families, workplaces, first responders, communities, and schools. His wife, a pediatrician, has helped shape that vision. “Why should we wait until someone is 40 or 50 and develops high blood pressure, diabetes, or vascular disease before we start talking about healthy habits?” he asks.

Mehta and his family live in Short Hills, where he says it was the community that drew them in. “It’s a wonderful place to raise our three children,” he says. It also feels like the right place to begin this work.

At home, the goal for his family is to make wellness a natural part of their routine rather than striving for perfection. “We’re definitely not perfect,” he says. Instead, the focus is on making health feel realistic: moving every day, eating more whole foods and vegetables, drinking water, protecting sleep, and having a sense of purpose.

What keeps Mehta motivated after years in medicine is that the work still matters every day. There is still something extraordinary about helping restore someone’s function after a stroke. But now, his sense of purpose has widened. “Early in my career, I wanted to become really good at treating strokes,” he says. “Now I also want to become really good at preventing them.”
