Many of us find ourselves wondering if our brain is working as efficiently as it did when we were younger. Research shows most likely it is not. Various studies suggest memory problems often “reflect a slower processing speed and poor encoding and retrieval of new memories as a result of diminished attention.” However, while normal aging causes seniors to process new information slower; judgement and reasoning powers remain largely intact. Researchers say in the same way we cannot jump as high or run as fast as we did when we were children; our thinking process also begins to slow down. By the time we are in our 50s or 60s, this can interfere with remembering things, solving problems or learning new information. Structural changes in the brain regions involved in memory processing such as the hippocampus and the frontal lobes all experience anatomical and neurochemical changes as we age. Concentration can be affected by the natural loss of receptors and neurons. Outside factors such as...
