Broad-based memory training program shows results

As the number of older adults increases, so does the number of misplaced car keys and forgotten names. As a summary of brain training research explains, the brain is a complex organ with over 100 billion nerve cells (neurons), linked by synapses and activated by neurotransmmitters. As people age, the number of neurons and synapses declines. Yet, research indicates it may be possible to improve some brain functions (German Institute for Quality and Efficiency in Health Care).
