If you are diagnosed with hypersomnia, your doctor can prescribe various drugs to treat it, including stimulants, antidepressants, as well as several newer medications (for example, Provigil and Xyrem).
You may have your 2015 RMD made payable directly to the charity (provided it meets the IRS definition of a qualified charity), and then designate it as a qualified charitable distribution on your tax return. You'll have satisfied your distribution requirement, and you won't have to pay income taxes on that money.
However, if the amount of a distribution is greater than the beneficiary's qualified higher education expenses, a portion of the earnings is taxable. You'll receive a Form 1099-Q (PDF) from each of the programs from which you received a QTP distribution.
