What is a silent stroke?

A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.

What are the signs of a silent stroke?

What happens when you have a silent stroke?

During a silent stroke, an interruption in blood flow destroys areas of cells in a part of the brain that is "silent," meaning that it doesn't control any vital functions. Although the damage will show up on an MRI or CT scan, it's too small to produce any obvious symptoms.

Is a silent stroke serious?

They're called silent strokes, and they either have no easy-to-recognize symptoms, or you don't remember them. But they do cause permanent damage in your brain. If you've had more than one silent stroke, you may have thinking and memory problems. They can also lead to more severe strokes.

Can silent strokes be treated?

Depending on the extent of damage, treatment may include thrombolysis, a process used to dissolve blood clots and restore blood flow through the use of medication. It may also be treated with medication only to relieve an underlying condition like high blood pressure (which is a major risk factor for silent strokes).

Do mini strokes show up on MRI?

Brain magnetic resonance imaging (MRI) is the preferred and most sensitive modality after transient ischemic attack (TIA) or minor stroke. It should include diffusion-weighted imaging (DWI) and should be completed within 24 hours of symptom onset^1,2; its use is 3-fold.
