What is Mental Acuity?
Mental acuity is a measure of the sharpness of the human mind. The measure of mental acuity usually considers focus, memory, concentration and understanding, but does not measure intelligence. This is a way of talking about how well or poorly the brain is functioning, not about its ability to perform complex functions or the amount a person has learned in his or her lifetime.
While there are many tests of mental sharpness available, most people use estimations of mental acuity not as a way of measuring how smart someone is, but as a way to figure out if someone's brain is functioning better or worse than usual due to factors such as distraction, disease, or fatigue.
A decrease or increase in mental abilities is sometimes difficult to measure because a person's mental sharpness is individual. This means that even if brain function could be considered low for a person's age group, that doesn't always imply a loss of brain function. It is important to think about a person's baseline acuity and gauge loss or improvement of function from that standardized degree of sharpness. Often, people themselves recognize a change in mental function before other people begin to notice the effects, and so are able to recognize that change as a symptom better than anyone else.
Some factors affect mental acuity drastically, and often in ways that cannot be changed. Alzheimer's disease is often characterized as causing serious and permanent loss of mental acuity. Other medical problems affecting the brain, such as cancer or encephalitis, can cause a decrease in mental sharpness. Prolonged drug use can also cause permanent damage that will affect the brain's ability to function long after the drugs have left the user's system.
There are also short-term situations that can have a negative effect on mental acuity. Some drugs act on the brain in such a way that mental sharpness is decreased. Other conditions, such as being excessively tired or extremely stressed, can make it difficult for the brain to perform tasks with which it typically has no difficulties. Distractions can also result in an apparent decrease in mental acuity, whether these distractions are internal concerns or external interruptions. Most of these issues are isolated, and acuity is regained after the disturbance is resolved and the brain has had time to adjust itself.
It is also possible to improve mental functions by engaging in activities and strategies that promote these functions. Certain dietary measures are thought to improve mental sharpness, either in the short term or long term. Staying engaged in mental pursuits, such as learning a language or playing a complex game, can also work to improve mental function overall. Exercise is also thought to improve these functions by improving blood flow. Mental acuity can be variable even for the same person and has a lot to do with the body overall, so it is important to take the best possible care of the body in order to achieve the best possible results from the mind.
Mutsy - I wanted to add that in Japan, the children start the school day with exercise. This makes sense because if the exercise increases the serotonin levels and the children are more relaxed yet focused they will perform better in school and be able to behave better as well.
I think that they should try that in the United States because you do feel a little sharper after a workout.
Subway11- I didn’t know that. I wanted to say that exercise also has a way of helping your levels of mental acuity.
Stephen Putnam wrote a book entitled, “Nature’s Ritalin for the Marathon Mind” talks about many studies that have been performed on children that suffer from ADHD.
The studies required these students to engage in high intensity exercise for at least fifteen minutes before they went to school which showed measurable levels of mental acuity for a period of up to four hours.
The exercise allowed these students to focus better in their school work. Who knew that regular exercise could also be brain exercise as well.
There are a lot of ways to increase serotonin. Exercise and antidepressants also boost serotonin levels.
An enhanced serotonin level will also allow for restful sleep and enhance one’s mood. Learning how to increase dopamine is also important to improve brain function and overall mental acuity.
You can raise your dopamine levels by eating ripe bananas, nuts like almonds, eating foods rich in antioxidants and limiting caffeine, sugary foods and those foods rich in fat.
Higher levels of dopamine allow you to make better decisions and allow you to feel a sense of happiness with a renewed calmness. It also allows for very restful sleep.
