According to a small scale US study, people who use anti-depressants may have poor driving skill.

Researchers from North Dakota University included 60 people in a driving simulation to test their concentration, reaction and steering.

They found that people who were on high dose anti-depressant courses had impaired driving skills.

But the researchers didn’t find whether it was the result of the actual condition or the pills caused those poor driving skills. According to researchers a larger study is needed to find it out.

The participants of that study were divided into three groups: Those who were on a high dose, those who were taking low dose and the people that were not on medication.

A series of common driving situations like reacting to brake lights, traffic signals and stop signs were recreated in the simulation they were put through.

The researchers will present their findings at the Annual Convention of the American Psychological Association on Monday.

According to the outcomes of the study, people who were not on medication got 69 points, people on low medication got 65 and those who were on high dose got 54.

The researchers concluded that either pills or the condition caused the problems.

Dr Holly Dannewitz who led the study told that they needed more work to do on this with a much larger study.
