Mental decline inevitable with age

So does a lot of scientific research. Not just the idea of failing to be active and thus losing the benefits of exercise.

Mental decline inevitable with age

New Study Proves Mental Decline is Not Inevitable 20 years ago, in a landmark article, researchers concluded that the human brain retains the potential for self-renewal throughout life.

Before this, scientists believed the adult brain was hard-wired and therefore not able to produce new cells. While most neuroscientists accepted the new findings, there has been an ongoing debate about whether this renewal ability applies to the whole brain, and whether it declines or stops altogether in seniors.

Animals Lose Ability to Generate New Brain Cells Maura Boldrini, associate professor of neurobiology at Columbia University, New York, together with her colleagues, studied the brains of 28 people aged between 14 and 79 shortly after death.

None had been diagnosed with any neurological or psychological condition. The researchers were interested in the hippocampus. As you probably know, this is a key region of the brain important for emotion, cognition and memory.

They already knew from studies in rodents and non-human primates that with aging the ability to generate new cells in the hippocampus declines.

Was this also true of humans? Using various techniques, they examined the volume of cells, the number of cells in different stages of maturity, and the degree to which new blood vessels were being formed. Boldrini summed up their findings.

Factors Affecting Cognitive Aging

We also found equivalent volumes of the hippocampus across ages. It seems that indeed humans are different from mice — where [neuron production] goes down with age really fast — and this could mean that we need these neurons for our complex learning abilities and cognitive behavioral responses to emotions.

There is hope for us all in our twilight years. New neurons in older brains were less able to make connections, there was less vascularization blood vessel formationand a smaller pool of progenitor cells.

These are similar to stem cells but are more limited in the types of cell they can become and in their ability to self-renew. Boldrini believes these factors have the potential to compromise our ability to think and our ability to navigate emotional ups and downs in old age.

Memory and aging

A new review wades into the controversial, ongoing debate on whether age-based testing of physician competence is needed, and if so, how best to go about it. There’s an inevitable decline in ability across the lifespan, or so we’ve been told.

This idea that we have to deteriorate as we age has had widespread and pervasive traction in our society. About the Author Sarah J.

Fortunately, proactive lifestyle changes, cognitive training, and nutritional interventions such as phosphatidylserine and glyceryl phosphoryl choline have been shown to decrease the rate of intellectual decay and potentially reverse age-related cognitive decline.
