If we want to remain mentally fit, it is useful to know about our own genetic disposition. The preconditions for dementia/Alzheimer’s are written in our genes. And there have been some recent findings on this front, including those of Dr Magdalena Götz, a Professor of Physiological Genomics who directs the Institute for Stem Cell Research at the Helmholtz Center in Munich. It was long believed that our neurons are first formed and then grow old and die. We now know, however, that new nerve cells can form, even at a later stage in life.
Recently, cognitive training methods have been developed (brain teasers) which – depending on the genetic disposition of the individual – can stimulate the growth of nerve cells in very important areas of the brain. Even if someone is already suffering from dementia or has had a stroke, damaged nerve cells can be repaired. Consequently, we can recommend to someone on the basis of a genetic test that they should do brain teasers to repair their damaged nerve cells.
