Grants and scholarships are not the same. A grant is non-profit, tax-free, and not just for education. It can also be government-based, and doesn't necessarily just pay for education. Scholarships are typically for privately run higher education, with one of the key requirements being a maintained GPA (grade point average).
The IDEA (Individuals with Disabilities Education Act) has been in use since December of 2004. IDEA includes a list of the 13 different disabilities that are recognized, and offer help (See Additional Resources Below).
Due to the additional needs of students for special education, there are grants and scholarships available. See which ones you could be eligible for (See Additional Resources Below); there are others as well.
Thanks to programs such as IDEA, or government-sponsored funding, there are many more grants or scholarships that are special-education focused.
There are many people who went to a university with special education needs: Helen Keller, Sir Isaac Newton and Frank G. Bowe ( a professor and the first person to speak to the UN about disabilities).
