BAKERSFIELD, Calif. -- Over the last half century, increasing numbers of Americans have been diagnosed with a mental health problem. The numbers are on the rise thanks to greater recognition and awareness of illnesses such as depression, alcoholism and eating disorders.

But patients who suffer from mental health issues often have trouble getting treatment, according to a series of reports in the journal Health Affairs.

Researchers discovered that the U.S. spends less than $150 per person treating mental health problems --- compared to more than $2,600 per person for all other types of health issues.

They also found that seniors had trouble connecting with doctors to receive treatment.

But there were positive signs as well. More insurance companies are now providing mental health benefits. Also, Americans are receiving more drug treatments -- such as antidepressants or antipsychotic medications -- for their mental health problems.

Drug therapy has increased by 50 percent in children and more than doubled among seniors since 1996.

Overall, researchers diagnosed the state of mental health care in America as getting better but not yet well.
