"Brain training" is a multi-million dollar industry. These activities are intensive computerized training exercises designed to improve your cognitive ability — to grow your brain.
In a recent issue of Nature, researchers recruited more than 11,000 participants and divided them into different study groups. These groups had "brain training" several times each week on tasks that were supposed to improve reasoning, memory, planning, eye-hand coordination and attention span. Each participant was tested on basic mental function before and after the six weeks of training.
Moderate canabis and ecstasy use reduce memory and attention in young adults.
The regular use of some illegal drugs may cause cognitive impairments. Two of these substances are "ecstasy" and "canabis". Recent research has focussed on attention and memory in a community-based sample of young adults derived from a large-scale epidemiological study. Subjects were sampled with varying degrees of lifetime drug use.
A dose-response relationship was found for poorer episodic memory function when ecstasy and cannabis were used. There was also a stronger tendency for attention to lapse with the higher use of these drugs.
PositiveTip: For maximum memory and alertness stay away from all illegal drugs.
