Intensive training for aphasia: Even older patients can improve

A study published in Brain and Language found that six weeks of intensive language therapy improved naming objects and cognitive potential in seniors with chronic aphasia. The therapy also integrated the default mode network, a brain system involved in 'on standby' activity, suggesting long-term recovery potential.

Most physicians do not meet Medicare quality reporting requirements

A new study shows that fewer than one-in-five healthcare providers meet Medicare PQRS requirements. Radiologists are nearly twice as likely to qualify for bonuses, but face penalties if they don't improve their documentation and reporting. The study found that radiologists collectively may face penalties totaling over $100M in 2016.
