Dr. Adam Hampshire, who helped develop a variety of brain-training tests by the Medical Research Council at Cambridge University, argues that demonstrating improvement on tasks performed through these brain-training games does not provide a sufficient claim of a brain-training or brain-altering affect. The article continues: Most research that suggests brain-training works is fraught with difficulties: little has been peer-reviewed or conducted alongside control groups. Several companies use scans of brains “lighting up” to support claims that their programmes are effective, but these simply show a measure of the energy that the brain is using rather than providing any evidence that the brain is being altered in any long-term way. Moreover, it is unclear whether training benefits are only evident for certain sectors of the population – for example children, patients or older people.
