Is it a stroke or not cat scan of brain showed nothing but doctors say you had cva?

It is possible to have a transient ischemic attack (TIA), or mini-stroke, without any visible signs on a brain scan. TIAs are temporary interruptions of blood flow to the brain that can cause symptoms similar to a stroke, such as sudden weakness, numbness, or speech difficulty. However, TIAs usually resolve on their own within a few minutes and do not cause any permanent damage to the brain.

If you have experienced any symptoms that may be related to a TIA, it is important to see a doctor right away. Even if a brain scan does not show any signs of a stroke, your doctor may still recommend further testing to rule out other potential causes of your symptoms.

In some cases, people may experience a stroke without any symptoms. This is known as a silent stroke. Silent strokes can occur for a number of reasons, including having a TIA that does not cause any noticeable symptoms or having a stroke in an area of the brain that does not control any critical functions.

Silent strokes can be dangerous because they can lead to long-term complications, such as cognitive impairment and dementia. However, they can also be a warning sign of future strokes that may cause more severe symptoms.

If you are concerned that you may have had a stroke, it is important to see a doctor right away. Even if you do not have any symptoms, your doctor may still recommend further testing to rule out a silent stroke.
