Several key elements may help differentiate the stroke mimic from an actual stroke; these include the nature of the presenting complaint, certain epidemiological factors, timing of onset, the presence of signs or symptoms from the anterior vs. posterior cerebral circulation, and the choice of imaging modality.

Can stress mimic a stroke?

How do doctors know if you had a stroke?

If a stroke is suspected, a CT scan is usually able to show whether you have had an ischaemic stroke or a haemorrhagic stroke. It's generally quicker than an MRI scan and can mean you're able to receive appropriate treatment sooner.

How do you rule out a mini stroke?

Diagnosis and Tests

The doctor will do some simple quick checks to test your vision, muscle strength, and ability to think and speak. Diagnostic testing consists of either a computed tomogram (CT) or magnetic resonance imaging (MRI) scan of the brain and carotid arteries to determine the possible cause of the TIA.

How long will a stroke show up on an MRI?

Unlike a CT scan, which takes several hours to reveal any blockages of blood flow, an MRI can uncover any brain damage within an hour of the onset of the stroke symptoms.

Do mini strokes show up on MRI?

You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.

Can you detect a stroke after the fact?

Detecting a Silent Stroke

If you have a silent stroke, you probably won't know it unless you happen to have a brain scan and the damage shows up. You may have slight memory problems or a little difficulty getting around. A doctor may be able to see signs of silent strokes without testing.

What is a medical Ghost stroke?

Ghost infarct core refers to the phenomenon that CT perfusion may overestimate infarct core on admission, especially in the early time window of a stroke, by predicting lesion in areas that will not show infarct on follow-up imaging 1. This mismatch is defined as the initial infarct core - final infarct (>10 mL).

Why do I think I'm having a stroke?

The Symptoms That Could Mean You're Having a Stroke

What happens if a mini stroke goes untreated?

Even if a major stroke is avoided, repeated mini strokes can have a cumulative negative effect on one's brain health and cognitive function. In severe cases, vascular dementia may result from untreated cerebrovascular events.

What can mimic a stroke on an MRI?

Epilepsy. Epilepsy is one of the most frequent stroke mimics. Some symptoms, such as headaches, involuntary movements, incontinence or postictal confusion, may be helpful pointers against stroke.
