we posses and being able to effectively tap into this mental resource oftentimes is the difference between success and failure. It is a necessary component at work, at school, or even when carrying on a casual conversation with friends. For those that struggle with concentration even the slightest distraction can fracture their focus, possibly leading to a series of missteps, resulting in unwarranted frustrations and failures.
concentration and focus? Let’s explore the biological aspect of lack of concentration/focus/attention.
action of chemicals within the brain called neurotransmitters. A neurotransmitter is a small chemical messenger that allows one neuron (nerve) to communicate with another. When an upstream neuron gets excited and wants to relay information to the downstream neuron, it releases the neurotransmitter molecules into a closed connection called a synapse. The neurotransmitter then crosses the space to the downstream neuron’s membrane and binds to specific receptors that cause an effect inside the receiving nerve. Most experts believe for the brain to concentrate well two neurotransmitters must not only be balanced with one another but also with other currently unknown neurotransmitters in different areas of the brain. The two brain messenger chemicals most likely responsible for lack of concentration are norepinephrine and dopamine. These neurotransmitters are distributed throughout the brain in specific locations, and they have different effects based on the types of receptors involved in chemical interactions and the location. There is an unprecedented amount of research dollars trying to unravel the biological wizard behind the curtain of concentration, which is closely associated with short attention span, lack of focus, or inattention. Are they closely linked or simply synonyms for one another? That question is a subjective and the answer could be yes or no depending on what perspective you are looking at it from. Some of the more creative theories about lack of concentration focus on the balance between norepinephrine and dopamine in the various areas they affect, including the idea that one neurotransmitter has more effect in one hemisphere of the brain than the other. Most of the neurons that have norepinephrine as their transmitter are contained in one area of the brainstem, the locus coerulius, part of the reticular activating system. This is the area of the brain that controls the general level of activation of your nervous system (how alert you are, whether you are awake or asleep). So the next time you are in a mental fog not being able to focus blame it on the locus coerulius! When the boss says, “Bob why don’t you have that project finished, are you having a problem with concentration?” Simply, tell him that your locus coerulius isn’t working right today but as soon as you your norepinephrine gets up to speed you will finish your work in record time. But wait could it be the neurotransmitter dopamine that is causing concentration to wander?
most important for concentration is the part that projects to the prefrontal cortex and is probably responsible for significance, meaning, and motivation. So when your dopamine isn’t quite right you lose that motivation that is a very important part of concentration. For instance, let’s say that you have two projects to do. One you are getting paid for and the other you are doing as a favor to a friend. Which one will you do first and will each one get the same amount of attention. Perhaps, you will try to give each one your total attention but chances are the one you are getting paid for will get done faster and be easier to concentrate on. One way to think about lack of concentration is an imbalance between both norepinephrine and dopamine. When you have too much norepinephrine working, you are agitated, and can only pay attention to things that are threats or targets of opportunity. When you have more dopamine rattling around in that thick skull of yours you may get stuck on repetitive actions. An example of a dopamine imbalance would be the ability to focus well on one piece of work but not be able to move on to the next. In other words you are continually getting stuck on one project or assignment and can’t seem to move on. I have told the boss that my norepinephrine and dopamine just aren’t getting it done in my locus coerulius and prefrontal cortex and he is only giving me a blank stare. What should I do now? Let’s look at a few ways to try to get the most out of what is a less than perfect situation. In layman’s terms when you aren’t firing on all cylinders try these steps. *Manage distractions: Learn to recognize things that easily distract you, and develop techniques for getting back on task. For example, if you have a window in your office, you may need to keep the blinds down or curtain closed whenever you need to concentrate. If pictures on the walls or your desk frequently attract your attention, get rid of them. Nevertheless, some people find it easier to concentrate when surrounded by chaos; figure out what works best for you before putting yourself in solitary confinement. *Take breaks: I knew you would love this one! Taking a break every half hour or so to walk around or stretch can help you focus. While a little physical activity is ideal, you can also just take an occasional daydream break, it might just rebalance those neurotransmitters. A word of caution; daydreaming or napping too long makes it difficult to refocus your attention so keep it short. *Use music or sound: Every person has an Achilles heel that knocks them out of their concentration mode. A baby crying, a particular tone of voice, an overbearing or belligerent boss, or maybe even that annoying ring-tone your co-worker just downloaded. Some find that listening to their favorite music or background sound helps mute out many of these distractions and improves both motivation and concentration. Depending on your work or school environment, you may need to ask for permission to play music or sound; obviously you may be required to use earphones. Chances are this simple change may help you become focused resulting in increased motivation and productivity. Asian Ginseng and Mental performance People who take ginseng often say they feel more alert. Several studies report that Asian ginseng may slightly improve thinking or learning. Early research shows that Asian ginseng may improve performance on such things as mental arithmetic, concentration, memory, and other measures. More research in this area, although not easy to do, would be useful. Some studies have also found a positive effect with the combination use of Asian ginseng and Ginkgo biloba. Can Certain Vitamins and Foods Help With Concentration? Most research suggests that this is indeed the case. Staying away from sugar laden foods and simple carbohydrates is a good place to start. Additionally, studies show that both omega 3 rich fish oil and vitamin B12 can help with concentration. All fruits and vegetables are packed with healthy vitamins and minerals. These fruit and vegetable foods help with mental focus: strawberries, blueberries, blackberries, tomatoes, broccoli, spinach, Swiss chard and kale. Leafy green vegetables contain folic acid, which is thought to help keep the mind focused as well as possibly prevent memory disorders such as Alzheimer's disease. Broccoli is rich in many vitamins, but one in particular — vitamin K — is said to be conducive to proper brain functioning. Berry foods help with mental focus and are thought to improve molecular signals in the brain due to their abundant supply of antioxidants. It's a good idea to add healthy fruits and vegetables to other nutritious foods we eat in order to increase our consumption of them. For example, some blueberries added to breakfast cereal can add extra healthy nutrients to start the day. But remember too much sugar on those blueberries and cereal can upset the whole blueberry cart. So use some discretion. It is also important to point out that while honey is slightly better for you, it still metabolizes rapidly, and is basically the same (from a concentration point of view) as simple table sugar.
