Today’s Headlines: The FDA-Approved Head Injury Test, Why Crossing Your Legs is Bad for You, and How Often You Should Get Mammograms

The FDA has approved the ImPACT test. The ImPACT test stands for Immediate Post-Concussion Assessment Cognitive Testing which is the first cognitive test of its kind to be approved. “ImPACT is intended for individuals aged 12 to 59 while ImPACT Pediatric was designed for patients aged 5 to 11. The devices are not intended to diagnose concussion, but are meant to test cognitive skills such as word memory, reaction time and word recognition. Results are compared to an age-matched control database of 17,000 cases or to a patient’s pre-injury baseline scores, if available.” The ImPACT program can be downloaded and taken on a computer.

Sitting cross-legged may be hurting you. Many people don’t know that the crossed-leg position is an unnatural way to sit. According to Dr. Naresh Rao from NYU Langone Medical Center, crossing your legs “is not a nice ergonomic position for your pelvis…The top knee puts pressure on the lower knee, while the pelvis is rotated and strained. The knees are at an unnaturally twisted angle, and you also hunch the lower back, giving it a little bit of torque.” Dr. Rao doesn’t think that alternating which leg you cross makes the situation any better and believes extended cross legging can lead to back problems and other issues.

Women with dense breast tissue might need to get mammograms more frequently. Roughly one percent of women between the ages of 50 and 74 have dense breast tissue, which could increase the risk for breast cancer. “The research recommends that women older than 50 with dense breast tissue who have higher-than-normal risk of developing breast cancer should get annual mammograms. Many women, however, could go as long as three years between mammograms without increasing their risk of death from breast cancer, the study found.” The general recommendation for mammograms is every two years, although this suggested time frame may change based on a woman’s low or high risk density. Researchers recommend speaking with your physician to determine the screening time that is best for you. (LA Times)
