No not certified. There are certifications for neuro nurses, etc, and perhaps for stroke in general.
For those check out AANN website: http://www.aann.org/
You need work experience in the field to get these certifications (and pretty much any major certifications in nursing that allow you to put fancy letter after your RN designation), including wound care.
This is a "certificate" to prove that you took the NIH Stroke Scale (how to do an in-depth stroke assessment) course. Nobody without this certificate should be doing these assessments, so technically it could be considered a type of certification.
You can get up to 18.0 CE units for this course:
"Continuing Education Accreditation - Nurses
The American Heart Association is accredited as a provider of continuing nursing education by the American Nurses Credentialing Center’s Commission on Accreditation.
The maximum number of hours awarded for this CE activity is 18.00 contact hours"
Online Stroke Treatment courses through AHA
If you are interested in Stroke courses (Prehospital and Hospital Stroke Treatment and Management) through AHA Online, it's a different website: www.AHAonline.org
And that's where you can find the hybrid BLS ACLS and PALS classes (only a portion of the book learning stuff can be done online, you still have to go in for some classroom and skills work- spread the word that these courses are a GREAT way to learn the basics and NOT a shortcut to learning- many people are under the impression that this is a shortcut around learning in the classroom- personally I learn way more this way because I arrive at the classroom with the basics hammered down tight. )
I took the stroke courses here, they provide CE units for the Stroke Hospital Care course. This is stuff you learn in ACLS but they go a little deeper and it is good reinforcement. These courses are going to focus on the initial Cincinatti stroke scale/FAST, ER role, assessment and treatment, thrombolytic therapies (rtPA), WHEN to do your NIH scales etc.
Other CE courses can be found all over the internet on stroke and neuro-related topics such as TIA, etc.
Hope this serves as a very comprehensive answer to your question.
