Can an mri detect post concussion syndrome?
A regular MRI usually cannot be used to detect post-concussion syndrome. A regular MRI detects structural damage to the brain, but PCS is not caused by structural damage. Because of this, many individuals with PCS are told they’re fine and that the symptoms are all in their head — due to normal MRI results.
What are signs of DNA damage?
Some changes, like grey hair and wrinkles, are easily visible. Others, like high blood pressure, often go unnoticed, but can be deadly. Just as our body shows signs of ageing, so does our genome. Damage comes from chemical reactions that alter our DNA, and from errors introduced when it is copied.
How is post-concussion syndrome diagnosed?
There is no definitive test for post-concussion syndrome. Diagnosis is mainly based on a history of head injury and reported symptoms. A physical exam, and perhaps a CT or MRI scan of the head, may be done to evaluate symptoms.
Can radar detect storms?
Radars. Weather radar is very important to meteorologists because it can detect rain and severe weather even when it is cloudy or dark. Doppler radar sends out electromagnetic wave fields that can be reflected back to the radar by things in the air like precipitation.
