Tests May Predict Driving Safety in People with Alzheimer’s Disease

10.02.2009
Doctors may be able to use certain cognitive tests to help determine whether a person with Alzheimer’s disease can safely get behind the wheel. The research is published in the February 10, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.

“The number of people with dementia is increasing as our population ages, and we will face a growing public health problem of elderly drivers with memory loss,” says study author Jeffrey Dawson, ScD, with the University of Iowa in Iowa City.

In the study, 40 drivers with early Alzheimer’s disease and 115 elderly drivers without this diagnosis underwent a combination of off-road tests that measured thinking, movement and visual skills. The participants also drove a 35-mile route in and outside the city. Driving safety errors were recorded by a driving expert, based on a video review of the drive.

The research found drivers with Alzheimer’s disease committed an average of 42 safety mistakes, or 27 percent more than the drivers without Alzheimer’s disease, who made an average of 33 safety errors on the test drive. The most common mistakes were lane violations. For every five years older the participant was, the number of safety errors went up by about two and a half, whether or not they had Alzheimer’s disease.

Among drivers with Alzheimer’s disease, those who performed better on the off-road tests made fewer on-road safety errors.

“The goal is to prevent crashes while still maximizing patients’ rights and freedom to be mobile,” said Dawson. “By measuring driver performance through off-road tests of memory, visual and motor abilities, we may be able to develop a standardized assessment of a person’s fitness to drive.”

The study was supported by the National Institute on Aging.

The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as multiple sclerosis, restless legs syndrome, Alzheimer’s disease, narcolepsy, and stroke.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
