‘Slowed Brain-activity’ in frequent mobile phone users

In the September issue of the International Journal of Neuroscience a study will be published on the long term effects of Mobile Phone use on brain function. [...] frequent mobile phone users showed improved focused attention. This was explained by a learning effect due to making more phone calls in busy environments, whereby people learn to focus better on the phone call and filter out irrelevant environmental information. However, the brain activity from frequent mobile phone users shows more slow activity (increased Delta and Theta) and a slowing of the Alpha Peak Frequency. These effects could not be explained by the differences in personality and focused attention. “In Alzheimer’s dementia you also find a severely slowing of brain activity.
