People who suffer a stroke may be able to recover initially, but a new study finds they're likely to become dependent on someone else over the next five years.

Researchers at Columbia University studied data collected on 525 stroke patients. The patients were tested on their ability to conduct regular activities six months after their stroke, and then every year for five years.

They found the odds of having a full recovery dropped by 9% every year. A patients' insurance status played a major role.

Those who were uninsured or covered by Medicaid were significantly more likely to lose function over time.

In other health news, the CDC says people with HIV are being diagnosed too late in the disease process, and not enough is being done to screen high school students.

A study finds nearly 40% of HIV positive patients progress to aids within one year of diagnosis, 45% have aids within three years.

Experts say it generally takes 10 years to progress from HIV to aids, so this study shows many people have the disease and are waiting too long to be tested.

Friday June 27th is national HIV testing day.
