The women who had chemotherapy fared much worse than the control group on tests of verbal memory, cognitive processing speed, executive function, and psychomotor speed.

Previous studies suggested that "chemo brain" can persist for five years after treatment, but this study is the first to show possible permanent cognitive damage.

More Americans are turning to the emergency room for routine dental problems - a choice that often costs 10 times more than preventive care and offers far fewer treatment options than a dentist's office, according to an analysis of government data and dental research.

Most of those emergency visits involve trouble such as toothaches that could have been avoided with regular checkups but went untreated, in many cases because of a shortage of dentists, particularly those willing to treat Medicaid patients, the analysis said.

The number of E.R. visits nationwide for dental problems increased 16 percent from 2006 to 2009, and the report released Tuesday by the Pew Center on the States suggests the trend is continuing.

Emergency rooms generally can offer pain relief and medicine for infected gums but not much more for dental patients. And many patients are unable to find or afford follow-up treatment, so they end up back in the emergency room.

Preventive dental care such as routine teeth cleaning can cost $50 to $100, vs. $1,000 for emergency-room treatment.
