Greetings fellow posters and stroke survival enthusiasts.
After reading the original post, and thinking about what the poster @RobbieJ asked viz,
I found myself losing sleep which is not a good thing for already sleep deprived carers
Now, as is my wont in these situations, I had to get to the bottom of this.
Why is it that a simple question cannot be answered in a simple way? Why is it that the medical profession must make things difficult to understand, be ambiguous, be inconsistent etc?
I started by looking up definitions in the dictionary and found the following:
small - could be 1) of a size that is less than normal or usual or 2) insignificant; unimportant.
Stroke - I went for the NHS definition : A stroke is when blood stops flowing to a part of your brain .
From this the answer to “What is a small stroke?” might be
A small stroke is when blood flow to the brain was stopped for an insignificant or less than normal amount of time.
Does that explain it?
Possibly not, so then more research. Outcome as below:

Stroke – Definitions (Based on NHS UK)
Stroke
A stroke is when blood stops flowing to a part of your brain. It can affect things like speech and movement, and take a long time to recover. A stroke needs urgent medical help in hospital because it can be life-threatening.
Types of Stroke
The different types of stroke include:
- an ischaemic stroke – this happens when a blood clot blocks blood flow to the brain. It’s the most common type of stroke
- a haemorrhagic stroke – this happens when a blood vessel bursts
- a transient ischaemic attack (TIA or mini stroke) – this is when the symptoms of a stroke do not last very long (less than 24 hours)
A TIA should be treated as urgent. If you do not get immediate medical attention, you could be at risk of having a full stroke.
Note/Comment/Observation
It is said (NHS) that a TIA should be treated urgently, yet is it not the case that most people do not even know they have had a TIA? And if so, then how is it ever going to get treated urgently?
Transient ischaemic attack (TIA)
A transient ischaemic attack (TIA) or “mini stroke” is caused by a temporary disruption in the blood supply to part of the brain.
The disruption in blood supply results in a lack of oxygen to the brain.
This can cause sudden symptoms similar to a stroke, such as speech and visual disturbance, and numbness or weakness in the face, arms and legs.
But a TIA does not last as long as a stroke. The effects last a few minutes to a few hours and fully resolve within 24 hours.
Having searched everywhere on the NHS website I came across no mention of “small” stroke, indeed even a Google search did not return specifics for a “small” stroke. In fact, when I “Googled” for “What is a “small stroke”” the result pointed to a mini-stroke aka TIA.
As a result of my research and previous discussions and comments about the terminology we might encounter, and here I am also mindful of at least one of our members who requested “Plain English”, I have decided to offer my understanding about what is stroke.
Conclusion (in layman’s terms)
There are two types of strokes:
- Bleeds – haemorrhagic, when a blood vessel bursts and bleeds in the brain
- Clots – ischaemic, when a blood clot blocks blood flow to the brain. This is the most common type of stroke
That’s it, that is stroke in a nutshell.
Clots are the most common types of stroke and they come in different sizes ranging from “small” to “large”.
The small strokes are what is also known as “mini-strokes” or TIAs. These are short-lived and recovery is within 24 hours and can be as little as a few hours. Sometimes, they occur and there is no indication they have occurred.
Small (TIAs) are warnings – they alert you to the possibility of a larger stroke and hence the need to get diagnosed and treated quickly so preventative steps for the large stroke can be put in place.
To finish, I put it to you dear reader that a “small” stroke is a TIA.
You may not agree, but this is my attempt to demystify stroke terminology and apply the KISS principle. I have no idea why we told you have had a “small stroke” and then find there is no definition of it on the websites.
