Trusted way to prevent stroke

There is no single best way to prevent stroke, but the measures with the strongest evidence are consistent: control blood pressure, stop smoking, treat atrial fibrillation, manage cholesterol and diabetes, stay physically active and limit alcohol. Blood pressure is the one that matters most.

Quick answer

Blood pressure first

If there is one intervention that carries more weight than the others, it is blood pressure control. It is also the one most often left partly treated, because it causes no symptoms and the numbers drift. Knowing your actual readings, rather than assuming they are fine because you take a tablet, is the practical version of this advice.

The rest of the list

Stopping smoking produces a substantial reduction in risk. Atrial fibrillation, an irregular heart rhythm, markedly raises stroke risk and is highly treatable once identified, which is why an irregular pulse is worth investigating. Cholesterol and diabetes management, regular physical activity, limiting alcohol and treating sleep apnoea all contribute meaningfully.

Know the warning signs as well as the prevention

Prevention and recognition are two different jobs. Sudden face drooping, arm weakness or speech difficulty means calling 911 immediately, because stroke treatment is time-dependent in a way few other conditions are. A transient episode that resolves still needs urgent assessment: it is a warning, not a reprieve.

About this practice

Clinical Neurology Specialists has been physician-owned since 1998, when Leo Germin, M.D., FAANEM founded it. Five board-certified neurologists and four advanced practice providers see patients at the Las Vegas and Henderson offices, each with its own AANEM-accredited electrodiagnostic laboratory.

Clinical Neurology Specialists is an adult outpatient neurology practice for patients 18 and older. The practice performs no surgery and operates no imaging suite, infusion suite or interventional pain programme, and provides no emergency or inpatient care.

Emergency & crisis resources: Clinical Neurology Specialists is not an emergency service. For stroke symptoms, a seizure lasting more than five minutes or any medical emergency, call 911 or go to the nearest emergency room. For a mental health crisis, call or text 988 (Suicide & Crisis Lifeline).

Frequently asked

Questions about trusted way to prevent stroke

What is the best way to prevent a stroke?

There is no single measure that stands alone, though blood pressure control carries the most weight. Alongside it: stopping smoking, treating atrial fibrillation, managing cholesterol and diabetes, staying active, limiting alcohol and treating sleep apnoea. Knowing your actual blood pressure readings, rather than assuming they are controlled because you take a tablet, is the practical version of this advice.

What are the warning signs of a stroke?

Use FAST: Face drooping, Arm weakness, Speech difficulty, Time to call 911. Also sudden vision loss, sudden severe headache, and sudden loss of balance or coordination. Call 911 rather than driving to hospital, because treatment starts en route. Note the time symptoms began, because treatment eligibility depends on it and it is the first thing you will be asked.

What if the symptoms go away on their own?

That may have been a transient ischaemic attack, and it needs urgent assessment rather than relief. The risk of a full stroke is highest in the days immediately afterwards, which is exactly when it is most often dismissed. Risk of a completed stroke is highest in the days immediately afterwards, which is exactly when a resolved episode is most likely to be dismissed.

Does family history mean I will have a stroke?

No. It raises risk but does not determine the outcome, and most of the major risk factors are modifiable. A family history is a reason to be more attentive to blood pressure, smoking and rhythm problems, not a reason to assume it is settled.

What does a neurologist do about stroke prevention?

Assesses the cause where a stroke or transient event has occurred, arranges appropriate vascular studies, and sets secondary prevention. Transcranial Doppler is performed at both CNS offices; carotid ultrasound is arranged at an imaging facility and interpreted here. Identifying atrial fibrillation matters particularly, because it is both a major contributor and highly treatable once found.
