Our lifestyles play a major role in the proper functioning of our frontal lobe. Therefore, we must focus on both the positive things we can do and the negative things to avoid.

Drugs that damage our Frontal Lobes

1. Illicit drugs

2. Certain prescription drugs

3. Other legal social drugs:

        - Alcohol

        - Caffeine

            - Eight ways it impairs our brains

        - Nicotine

Illicit Drugs and Mental Impairment

We all know, without a doubt, the danger that illicit drugs play on our mental performance. We have all witness on the news the damage that was caused by individuals who were under the influence of drugs. However, it seems to be worse than we ever thought. There is growing evidence that drugs affect the functionality of the brain long after their initial usage. Research funded by the National Institute on Drug Abuse showed that college students who were habitual marijuana users had defects in their attention, memory, and learning even 24 hours after their last use of the drug.³² The effects on the brain were still evident long the high was over and the brain in essence functioned on lower terms. Marijuana has now been proven to harm the brain of the developing fetus. A mother who uses marijuana gives her child a lifelong legacy of brain impairment.³³

Prescription Drugs & Frontal Lobe Impairment

Many legal prescription and over-the-counter medications can also impair frontal lobe function. Any good medication reference book will prove this point clearly. You will find that many of these drugs have an influence on the central nervous system, and one of the most commonly affected areas of the central nervous system is the frontal lobe. On a personal note, my son suffers from seizures and one of the medications that he has to take caused his personality to change.

Alcohol Directly Effects the Frontal Lobe

If you have even witnessed a person drunk, then you know without a doubt that alcohol definitely effects the frontal lobe. In fact, alcohol is one of the world's most popular and known frontal lobe destroyer, yet it is legal just about everywhere

Not long ago, alcoholics and non-alcoholics were studied to see what effects alcohol had on the brain. The researchers used magnetic resonance imaging equipment, better known as MRI and positron emission topography or PET scan. The MRI was used to look at the actual structure of the brain while the PET scan was used to look at its function. What the researchers found among alcoholics, was a striking amount of gray matter loss in frontal lobe area. The gray matter is where bodies of brain nerve cells are concentrated. What this indicated was an actual loss of brain cells in the frontal lobe. On the other hand, the PET scans revealed that alcoholics showed a lower glucose metabolism, indicating less frontal lobe activity.³⁹

These impairments were not limited to heavy alcoholic users only. The researchers found a measurable decrease in abstract thinking ability among social drinkers as well. These individuals drank as little as one alcoholic beverage per week.

My friends, how can we serve the Lord if we can't understand what He desires of us. If our minds are destroyed, then we can't develop the mind of Christ! Scripture says, "Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise (Prov. 20:1). Let us not be deceived, alcohol impairs the mind and the mind that is impaired cannot please God.

Caffeine

Caffeine has far-reaching effects on the brain. This is not unexpected, since it is America's drug of choice for an early morning lift. However, a heavy price is paid for that stimulation. Let us look at how caffeine works and then explore some of its associated side effects.

Caffeine impinges on the brain's communication system in a number f ways. In exploring these relationships, we need to recall that brain cells talk to one another through chemical interchanges. nerve cells release chemical called neurotransmitters (or "chemical messengers") that are picked up by neighboring cells. These neurotransmitters then cause changes to occur in the cell that receives them. Some neurotransmitters cause stimulation of the recipient nerve cell, while others cause depression. Caffeine's widespread influence focuses primarily on its ability to affect the levels of two transmitters: acetylcholine and adenosine. Caffeine disrupts the brain chemistry by increasing the level of acetylcholine and interfering with the transmission of adenosine. Thus, caffeine upsets the delicate balance of nerve transmission in the brain, which may have devastating consequences. Adenosine tones down (or puts the brakes on) many aspects of brain nerve transmission. But caffeine weakens its power to do its work, thus allowing artificial stimulation of the brain from the caffeine.

The Brain's Adjustment to Caffeine

If caffeine is so good for us, as some lay people (and even some scientists) would like us to believe, it is interesting to note that the brain puts forth great effort to try to undo the effects of this popular legal drug. Under a situation of chronic exposure to caffeine, the brain tries to compensate in at least two ways. First, it decreases its production of acetylcholine. This appears to be a way to lessen the impact of the increased acetylcholine levels brought on by caffeine. Second, the brain increases its number of adenosine receptors. This is likely a response to give adenosine more of a voice in brain communication--in spite of caffeine blocking its role to some extent. Unfortunately, these brain changes contribute to caffeine dependency. Thus, brain structure and function have changed and consequently the brain actually comes to expect caffeine in its environment. This is one of the reasons why coffee users are so committed to their morning brew. If they do not get their caffeine, they fell that they are running at less than half-throttle. Even more so, if coffee users stop using the beverage, they are likely to develop withdrawal symptoms such as headache in addition to fatigue.

Caffeine Impairs the brain 8 ways

1. Tends to produce dependence

2. Can cause drug withdrawal reactions

3. Can cause or worsen psychiatric illnesses

4. Impairs physical and mental performance

5. Interferes with sleep

6. May influence the risk of other illnesses that in turn exert frontal lobe effects through physical or mental stress

7. May exert effects that impart on spiritual and social dimensions of our character

8. Can cause toxicity, and even death.

Other Potential Problems with Caffeine

• Caffeine may be a co-carcinogen, contributing to the development of cancers of the kidney, breast, colon, pancreas, ovaries, and bladder.

• Increase risk of low birth weight in infants born to caffeine-consuming mothers.

• Elevates blood pressure by 3-5 mm Hg.

• can cause palpitations and more dangerous heart rhythms.

• Stimulates excess stomach acid production and gastroesophageal reflux which is a cause of severe heartburn (for both caffeine and decaffeinated coffee).

• May increase symptoms of premenstrual syndrome (PMS).

Nutrients that Impair our Frontal Lobes

• Large amounts of sugar
• Eating much meat

Superior Diet

• Grains, fruits, nuts, and vegetables constitute the diet chosen for us by our Creator.
• These foods, prepared in as simple and natural a manner as possible, are the most healthful and nourishing.

"They impart a strength, a power of endurance, and a vigor of intellect that are not afforded by a more complex and stimulating diet."
