The breakthrough in our approach is to go after the three root problems described above that the aging brain faces. Addressing the root problems gets to the symptoms, such as memory loss and waning problem-solving and communication skills. Our extended scientific team has looked across brain systems at what is happening on a biological and…
As the brain’s ability to encode the things that we hear and see slowly deteriorates, the brain adapts by slowing down the pace at which it operates. Imagine that you are out at dusk, trying hard to figure out what you see in the distance. You must look at it for a longer time than…
As we age, the brain’s production of neuromodulators (brain chemicals that help with learning and remembering) drops sharply. For example, studies suggest that after age 40, with each passing decade people produce an average of 13% less of the critical neuromodulator dopamine than in the previous decade. Neuromodulators – especially dopamine, acetylcholine, norepinephrine, and serotonin…
Several kinds of changes in people’s bodies make it difficult for their brains to represent what they hear and see as accurately as they did when they were younger. Hearing and vision rarely improve with age. In addition to the well-known declines in the function of the ear and the eye, there are declines in…
Like most older machines, the brain undergoes slow physical deterioration. This is aggravated by declining use. In the early part of life, the rapid pace of learning makes continuous, powerful changes in brain machinery. However, as people get older, they often become like concert violinists who have stopped practicing. Resting on their laurels, they still…
Cognitive decline is driven by a number of underlying interacting changes in the brain that, together, gradually and significantly cause a decline in brain function. There are three key underlying changes in the brain that cause this decline: A slowing in brain processing speed. A weakening of brain signals from the senses. A decrease in…
Cognitive decline — a gradual weakening of understanding, thinking and remembering— is a natural and expected part of aging. This has been confirmed by numerous studies on memory, response time, attentiveness, the ability to speak and to understand what others are saying, and even IQ. We all face a gradual loss in mental sharpness as…
You can engage the brain’s natural plasticity – its ability to change in response to stimuli – if you present the right stimuli, in the right order, with the right timing. This sounds simple enough, but figuring out how is not so simple. That’s why we have teams of brain scientists from around the world…
Although cognitive decline is a normal part of aging, studies have shown that using the right kind of scientifically designed cognitive exercises can significantly improve cognitive abilities in adults. Posit Science programs are specially designed to stimulate a high level of mental activity in order to engage, harness and direct the brain’s plasticity. Some of…
Brain plasticity is a powerful and natural force for driving beneficial changes in the brain. As the scientific community improves its understanding of specific neurological issues, we can create training activities designed to harness the brain’s plasticity to create and reinforce neural pathways for specific results. In other words, we are pioneering a whole new…
