"I, personally, have not noticed any mental/cognitive decline due to my relatively (CR-induced) low free testosterone (2.7 PG/ML). Some of this may be the result of using supplements (Gingko, AOR's Ortho-Mind) and/or maintaining a moderate exercise regimen, both of which I did not practice before CR.
However, I think the best advice for maintaining -- and even gaining -- cognitive abilities is simple: keep your brain/mind active and challenged. A great way to do this is to practice routine neurobics. The book Keep Your Brain Alive by Lawrence C. Katz has some very effective exercises that "increase mental fitness". An example would be to brush one's teeth using the opposite hand. The book is a very simple and quick read, yet it is based on well-researched science."

As the population of over 76 million Baby Boomers approaches middle age and beyond, the issue of preserving mental powers throughout greatly increased life spans has reached an almost fever pitch. There is a growing interest in - and optimism about - preserving and enhancing the brain's capabilities into senior years. With the help of powerful new tools of molecular biology and brain imaging, neuroscientists around the world have literally been looking into the mind as it thinks. Almost daily, they are discovering that many of the negative myths about the aging brain are, indeed, only myths: "Older and wiser" is not just a hopeful cliche but can be the reality. In much the same way that you can maintain your physical well-being, you can take charge of your mental health and fitness.
Although new and therefore not yet proved by large body of tests, Neurobics is based on solid scientific ground; it is an exciting synthesis of substantial findings about the brain that provides a concrete strategy for keeping the brain fit and flexible as you grow older.
From Theory to Practice
Jane reached into her pocketbook and fished inside for the keys to her apartment. Usually they were in the outside flap but not today. "Did I forget them?! No...here they are." She felt their shapes to figure out which one would open the top lock. It took her two tries until she heard the welcome click of the lock opening. Inside the door she reached to the left for the light switch...but why bother? Her husband would do that later. Touching the wall lightly with her fingertips, she moved to the closet on the right, found it, and hung up her coat. She turned slowly and visualized in her mind the location of the table holding her telephone and answering machine. Carefully she headed in that direction, guided by the feel of the leather armchair and the scent of a vase of birthday roses, anxious to avoid the sharp edge of the coffee table and hoping to have some messages from her family waiting.
The table. The answering machine. She reached out and brushed her fingers across what she believed to be the play button. "What if I push the delete button?" she thought, and again checked to make sure she was right. Yesterday it was so easy. She could have done all this simply by looking around. Today was different. She could see nothing.
But Jane had not suddenly gone blind. At age 50, she was introducing a lifestyle strategy called Neurobics into her daily activities. Based on recent discoveries in brain science, Neurobics is a new form of brain exercise designed to help keep the brain agile and healthy. By breaking her usual homecoming routine, Jane had placed her brain's attentional circuits in high gear. With her eyes closed, she had to rely on her senses of touch, smell, hearing, and spatial memory to do something they rarely did - navigate through her apartment. And she was involving her emotional sense by feeling the stresses of not being able to see. All these actions created new and different patterns of neuron activity in her brain - which is how Neurobics works.
This book will explain the principles behind Neurobics and how the exercises enhance the overall health of your brain as you grow older.
Brush your teeth with your nondominant hand (including opening the tube and applying toothpaste). You can substitute any morning activity - styling your hair, shaving, applying makeup, buttoning clothes, putting in cuff links, eating or using the TV remote.
* This exercise requires you to use the opposite side of your brain instead of the side you normally use. Consequentially, all those circuits, connections, and brain areas involved in using your dominant hand are inactive, while their counterparts on the other side of your brain are suddenly required to direct a set of behavior in which they usually don't participate. Research has shown that this type of exercise can result in a rapid and substantial expansion of circuits in the parts of the cortex that control and process tactile information from the hand.
Use only one hand to do tasks like buttoning a shirt, tying a shoe, or getting dressed. For a real workout, try using just your nondominant hand. Another exercise that associates unusual sensory and motor pathways in your cortex with a routine activity is to use your feet to put your socks and underwear in the laundry basket or pick out your shoes for the day.
