Managers Retain Memories Better

Managing others could induce healthy structural changes in the brain, enabling such persons to retain their memories well into old age.

Researchers with the University of New South Wales (UNSW) have, for the first time, identified a clear link between managerial experience throughout a person’s working life and the integrity and larger size of an individual’s hippocampus – the area of the brain responsible for learning and memory – at the age of 80.

Brain Exercises to Improve Memory
An active brain can certainly help in improving memory by strengthening the connections between neural impulses in brain.

The findings refine our understanding of how staying mentally active promotes brain health, potentially warding off neurodegenerative diseases such as Alzheimer’s. The study was presented recently at the Brain Sciences UNSW symposium Brain Plasticity –The Adaptable Brain.

The Symposium focused on research into “brain plasticity” that is revealing the brain’s ability to repair, rewire and regenerate itself, overturning scientific dogma that the brain is “hard-wired”.

“We found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus,” says Dr Michael Valenzuela, Leader of Regenerative Neuroscience in UNSW’s School of Psychiatry.

Brilliant Human Brain
The most amazing and complex organ in the entire universe, the human brain continues to remain an enigma.

“This could be linked to the unique mental demands of managing people, which requires continuous problem solving, short term memory and a lot of emotional intelligence, such as the ability to put yourself in another person’s shoes. Over time this could translate into the structural brain changes we observed.”

The research comprises the doctoral work of Mr Chao Suo, supervised by Dr Valenzuela in collaboration with Scientia Professor Perminder Sachdev’s Memory and Ageing Study based in Sydney.

Using MRI imagery in a cohort of 75-92 year-olds, researchers found larger hippocampal volumes in those with managerial experience compared to those without, even after accounting for any of a number of possible alternative explanations. While many male participants followed traditional management career paths, the effect was also seen in women who had taken on managerial roles in nursing or teaching, for example.
