The average time between a person suffering a stroke and dialling 999 for help was around an hour and a half last year, figures show.

It comes as the NHS has updated its criteria for identifying and acting on stroke symptoms in a major new campaign.

Strokes and mini-strokes are caused by a blood clot or bleed on the brain which cuts off the blood supply, killing brain cells.

They are the fourth single leading cause of death in the UK, with 38,000 stroke-related deaths each year, and can also lead to long-term disabilities such as paralysis, memory loss and communication problems without fast treatment.

Analysis of NHS data by the Sentinel Stroke National Audit Programme at King’s College London for 2023-24 showed that, of the more than 41,000 patients with a recorded time of symptom onset, the average time between first symptom and a 999 call being made was 88 minutes.

A poll of 2,000 adults in England found that more than half of respondents (57%) believed two to three symptoms of a stroke were needed before calling 999.

On Monday, the NHS will launch a new campaign urging the public to call 999 immediately if anyone experiences one of the three common symptoms – struggling to smile, having difficulty raising an arm, or slurring their words.

A new advert showing individuals with the example symptoms will run across TV, on demand and radio in England until mid-December, while a new film featuring stroke survivors listening back to audio recordings of their life-saving 999 calls has also been released.

Since 2009 the NHS has advised the public to remember the acronym FAST – face, arms, speech, and time – when spotting and reacting to signs of a stroke.

A sudden weakness or numbness on one side of your body, sudden loss of vision or blurred vision, memory loss or dizziness, and unsteadiness are all other symptoms that could indicate someone is having a stroke.

Stroke symptoms can be less obvious or dramatic than you might expect, but, even if it doesn’t seem like it, any sign of stroke is always an emergency and it’s vital you call 999 immediately

NHS national medical director Professor Sir Stephen Powis said the new figures highlight “very clearly” that more should be done to support people to recognise stroke symptoms in themselves and others.

He said: “Stroke symptoms can be less obvious or dramatic than you might expect, but, even if it doesn’t seem like it, any sign of stroke is always an emergency and it’s vital you call 999 immediately.

“This campaign is so important – greater awareness of the need to act fast and dial 999 could help save and protect many more lives, as we know that earlier recognition of symptoms and immediate action to call 999 can enable faster access to specialist treatment and the best chance of reducing long-term effects of a stroke.”

Around 100,000 people have a stroke in the UK each year and they can happen to anyone of any age.

However, those who are over 50, come from a black or South Asian background, or live with existing conditions such as high blood pressure are at increased risk.

Dionne Hudson, who features in the new campaign film, first noticed a strange feeling in her hand as though she could not reach or grip her phone, but her face and speech were unaffected so she went to sleep.

She called 999 after her symptoms worsened and was in hospital having a CT scan soon afterwards.

The 58-year-old, from Surrey, said: “The doctors were amazed that I had survived my stroke, as it had actually occurred the night before I called 999.

“Looking back, I was very lucky as the weakness in my arm was a clear sign of a stroke, but because I didn’t have a dramatic symptom affecting my face or speech, I didn’t consider that I should get help sooner.”

When someone has a stroke, it’s estimated they may lose around two million brain cells a minute, which is why rapid diagnosis and treatment is critical

Dr David Hargroves, NHS national clinical director for stroke and a consultant stroke physician, said: “When someone has a stroke, it’s estimated they may lose around two million brain cells a minute, which is why rapid diagnosis and treatment is critical – the first sign of a stroke might not seem like much, but face or arm or speech, at the first sign it’s time to call 999.

“Thanks to greater awareness of the symptoms and advances in NHS care, more people are now surviving a stroke than ever before, but there is much more to do help save lives and reduce the long-term impact of strokes. Acting FAST remains vital – whether it is a friend, loved one or even a passer-by, dialling 999 quickly saves lives.”
Each year the programme engages over 1.3 million people and prevents around 500 heart attacks and strokes a year

Public health minister Andrew Gwynne said: “It is important to treat a stroke quickly and raising awareness of symptoms is vital to saving lives.

“It is not just about recognising when a stroke is happening – we know that many of the causes of strokes are preventable, and this government is taking action to tackle the biggest killers such as heart disease and stroke.

“The NHS Health Check programme aims to prevent cardiovascular disease, including stroke, in people aged 40-74 years through assessing risk factors such as blood pressure and referring people to behavioural support and clinical treatment to reduce their risk.

“Each year the programme engages over 1.3 million people and prevents around 500 heart attacks and strokes a year.

“We are currently developing a new digital NHS Health Check enabling people to complete this life saving check in their own home.”
