Most of them have low retirement income because they took low-paying jobs in their working years. Brain training Current research has proven (through MRI) that brain training had been effective in improving memory even in persons with brain impairments or learning disabilities. The theory is that these daily mental activities may have improved blood circulation to the brain and improved its functions. If you are after comprehensive brain training, then it would work if you would be picking a program that does not only contain brain games. Make sure to pick a program that would help you in applying the techniques on your life, like improving your self-confidence, memory, and even develop speed-reading techniques. Brain-trained seniors can still outperform those untrained individuals in the mental abilities that they had received instructions before. Function loss and recovery Research had also discovered that just like losing muscle mass as a person ages, brain function also begins to decline with the passing of years. As attested to by MRI (magnetic resonance imaging), people who did their daily mental exercises have shown improved memorization skills. Interdependent components However, today s medical practitioners believe that brain training does not depend wholly on mental exercises which were used to stimulate the brain and develop further its cognitive power. This would help the therapist identify which activities are positive and negative for the patient which would be used for the following sessions. The waves are measure or recorded through the electroencephalogram or EEG. Sensors are attached to the scalp to monitor brain activity. Eventually, the signals are filtered and the feedback can be seen on a screen and can be heard through earphones or speakers. Focusing only on a single mental activity will not exercise all the cognitive domains needed to keep the brains agile. Furthermore, consistent and long-term mental stimulation appears to be the key to reducing risk of memory loss and dementia. If you can, also include activities that address areas for short-term and long-term memories, critical thinking, visual and spatial orientation, calculation and language.
