Stroke 

Someone has a stroke every five minutes in the UK, and strokes are the third most common cause of death. The cause varies from person to person but it's important to know what your personal risk factors are.

Transcript of Stroke

A stroke is a problem that happens

when the blood supply to the brain is in some way disturbed.

That can happen broadly in two main ways.

Either the artery carrying the blood to the brain

can become blocked with a little blood clot,

so just like your sink getting blocked,

the blood can't flow through any more,

and therefore the brain that's being supplied by that artery

is deprived of its oxygen, its food supply,

and the brain cells die.

That's the most common cause of stroke.

It happens in about 85 per cent of stroke patients.

The other type is haemorrhage, which happens in the other 15 per cent.

That's where a blood vessel ruptures and bursts

and allows blood to flow out into the brain cells

and that causes damage to the brain cells.

Both sorts of stroke result in a particular part of the brain

being damaged as a result of the stroke.

And the symptoms somebody gets as a result of their stroke

vary according to which particular part of the brain has been affected.

Maybe stroke's not really the right term for the condition,

because it sounds all too gentle.

Many of us would prefer it if the name was changed to brain attack,

in much the same way as heart attack.

Everybody knows if you have a heart attack, you dial 999,

come straight to hospital and you can be cured.

The same message isn't got across with stroke.

The first question I would ask if I had a relative with a stroke

is why did it happen and what could I have done

that might have enabled us to prevent that stroke?

Stroke is, for most people, a preventable disease.

It does not need to happen.

It's about identifying whether you've got high blood pressure

and treating that seriously,

knowing what your cholesterol is, getting that down to a low level,

taking exercise, not getting too fat, not smoking.

All the usual boring things that we're told to do

to prevent heart disease are equally applicable to stroke.

20 to 30 per cent of people who've had strokes get a warning sign,

something that we call a TIA or transient ischaemic attack.

That's basically a very brief episode of stroke-like symptoms,

maybe paralysis, loss of speech, some change in the vision,

which then gets better very, very quickly.

And if that happens, then it should be taken very, very seriously.

It is certainly possible to actually avert the stroke

if we actually treat the TIAs and the underlying causes very rapidly.

But if we don't, then 20 to 30 per cent of people with those sort of TIAs

will go on and have a completed stroke.

The next question I would ask if my relative had a stroke

would be what should I have done

actually at the time that the person had the stroke

in terms of minimising its effects?

And this is absolutely critical.

The quicker we can get people who've had strokes

into hospital and treating them,

the less severe the effects are likely to be.

So what we're trying to do is to teach people

to recognise the key symptoms of stroke.

The Stroke Association have done a major campaign

around something called FAST,

which stands for the Face Arms Speech Test.

So if you get weakness of the face,

if you get abnormality of the speech, if you get weakness of an arm,

any one of those or even all three, obviously,

it could well be a stroke.

Get to hospital as soon as possible. Dial 999.

If we can actually identify stroke quickly,

if we can get people scanned to find out what sort of stroke it is,

then for some patients we can give clot busting treatment,

which can have a dramatic effect

in terms of reducing long-term death and disability.

The recovery after a stroke can go on for a very long time.

One of the key messages that I give to my patients

is really not to give up too soon.

Find out what's available, find out what you need as an individual,

and then fight tooth and nail to make sure

that you get proper rehabilitation by people who know what they're doing.
