With the new tax bill if I claim my disabled parents I will not longer get a credit for them will I?

[Critter]

Nothing is final but here is the proposed changes:

Eliminated
Personal exemptions, which in 2017 reduce taxable income by $4,050 each for taxpayers, spouses and dependent children.

But any such change does not affect 2017 tax returns (filed in 2018).

[Hal_Al · Accepted solution]

That's correct. Personal exemptions for dependents (and the taxpayer himself) will no longer be allowed. It will be replaced by an  increase in the standard deduction . Which means dependents, other than children, are near worthless. Having a dependent might qualify you for Head of household, if you are not married

There never was an actual  tax credit for dependents. The dependent exemption was a $4050 deduction from income before tax was calculated.

The bill would creates a temporary credit for non-child dependents: It would allow parents to take a nonrefundable $500 credit for each non-child dependent whom they're supporting, such as a child 17 or older, an ailing elderly parent or an adult child with a disability.

Note that a tax credit (unlike a deduction) is a direct subtraction from taxes due.

Right, but also notice that personal exemptions are eliminated, so this makes up for some of that loss.
