What’s the Difference Between Stroke and Brain Hemorrhage?
Most people have heard terms like stroke, brain hemorrhage, or brain clot – but what do they actually mean? And how do they differ? In this article, we’ll break down what a stroke is, the two main types, and why understanding the difference matters – especially in emergencies.
Stroke – An Umbrella Term
A stroke is not a single disease – it’s a general term for sudden disruptions in blood flow to the brain. Strokes fall into two major categories:
-
Ischemic stroke (caused by a blood clot)
-
Hemorrhagic stroke (caused by a ruptured blood vessel)
In most countries, about 85% of all strokes are ischemic, and about 15% are hemorrhagic [1].
Ischemic Stroke – A Clot in the Brain
An ischemic stroke occurs when a blood vessel in the brain becomes blocked, usually by a blood clot. This stops oxygen from reaching parts of the brain, causing brain cells to begin dying within minutes [2].
Common causes:
-
Atrial fibrillation
-
Atherosclerosis
-
High blood pressure
-
Smoking or diabetes
Hemorrhagic Stroke – When a Vessel Bursts
A hemorrhagic stroke happens when a blood vessel ruptures, leading to bleeding in or around the brain. The leaked blood damages surrounding brain tissue and increases pressure inside the skull, which can be life-threatening [3].
Common causes:
-
High blood pressure
-
Vascular malformations
-
Blood thinners
-
Head trauma
How Can You Tell the Difference?
Stroke symptoms often look the same, regardless of type:
-
Sudden weakness or numbness in the face, arm, or leg
-
Difficulty speaking or understanding speech
-
Vision changes
-
Loss of balance
-
Sudden severe headache (more common in hemorrhagic stroke)
Since the symptoms are similar, the only way to tell the difference is through emergency brain imaging – usually a CT scan or MRI [4].
Type of Stroke | Cause | Approximate Share | Emergency Treatment |
---|---|---|---|
Ischemic stroke | Blocked blood flow (clot) | ~85% | Clot-busting drugs or thrombectomy |
Hemorrhagic stroke | Burst blood vessel (bleeding) | ~15% | Pressure control, surgery, supportive care |
Why Does the Difference Matter?
Because treatments are completely different. Giving clot-busting drugs to someone with a hemorrhage can make things much worse. That’s why getting the right diagnosis fast is critical [5].
Time is brain: with every minute of delay during an ischemic stroke, millions of brain cells die.
Stroke, Brain Hemorrhage, and Dementia
Regardless of type, a stroke can lead to long-term complications. Many people experience cognitive problems, such as memory loss or difficulty concentrating. Repeated minor strokes – especially ischemic – are a common cause of vascular dementia, where reduced blood flow slowly damages the brain over time [6].
Early diagnosis and prevention are key to reducing both disability and the risk of future memory disorders.
A personal alarm that can be triggered at any time
Sensorem’s personal alarm can automatically trigger the alarm in the event of a fall and then automatically call relatives using the watch’s built-in speakerphone with two-way communication. The user can also trigger the alarm manually by pressing the physical alarm button. The personal alarm works outdoors and has built-in GPS positioning so that relatives can see the user’s position on a map in the Sensorem app.
