Can a stroke be missed on a CT scan?
The brain tissue damage typically does not show up on the MRI until 24 hours after the event and 72 hours on the CT scan. Therefore, a CT scan will miss an immediate ischemic stroke but reveals a hemorrhagic stroke.”
Can a stroke not be detected?
Some people have strokes without realizing it. 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.
Can a stroke go undetected by MRI?
Although it doesn’t cause any obvious symptoms—most people who’ve had a silent stroke have no idea it occurred—the damage does show up on an MRI or CT scan. Silent strokes could interrupt the flow of information in the brain needed for memory, especially if several of them occur over time.
Can a mini stroke go undetected?
People who have mild strokes may feel like they’ve dodged a bullet since physical symptoms—blurred vision, difficulty speaking and weakness or numbness on one side of the body—usually disappear in a few minutes.
How often is stroke misdiagnosed?
They found that up to 12.7 percent of people later admitted for stroke had been potentially misdiagnosed and erroneously sent home from an ER in the 30 days preceding stroke hospitalization.
What are symptoms of a silent stroke?
Unlike events such as a heart attack where there could be obvious signs of discomfort or pain, a silent stroke may include the following symptoms:
- Sudden lack of balance.
- Temporary loss of basic muscle movement (bladder included)
- Slight memory loss.
- Sudden changes in mood or personality.
What other conditions can be mistaken for a stroke?
Conditions That Look Like a Stroke
- Seizures.
- Migraine.
- Low or High Blood Sugar.
- Bell’s Palsy.
- Brain Tumors.
- Multiple Sclerosis (MS)
- Conversion Disorder.
- Sepsis and Other Infections.
What happens after a silent stroke?
Researchers say that over time, the damage from silent strokes can accumulate, leading to more and more memory problems. “The more brain damage or injury that you have due to these silent strokes, the more difficult it is for the brain to function normally,” Dr. Furie says.
How do you treat a silent stroke?
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).
