A study published in the British Journal of Psychiatry found that brain-training, or what they referred to as a “cognitive stimulation therapy programme” improved cognition in seniors with dementia and that results “compared favorably with trials for drugs for dementia.” Britain’s National Health Service (NHS) also described a cluster of three studies indicating possible effectiveness of mental exercises as a therapy for dementia. More than 3,000 people were enrolled in these studies, some for up to five years, and the NHS said patients “showed significant improvements in auditory memory (processing spoken information) and attention.”
Report by A.Spector in 2003, published by The British Journal of Psychiatry named ‘Efficacy of an evidence-based cognitive stimulation therapy programme for people with dementia’
The conclusion was that the results compare favourably with trials of drugs for dementia.
