New study: even casual use of marijuana / cannabis alters brain

Reported by the UK Telegraph.

Excerpt:

Experimenting with cannabis on a casual basis damages the brain permanently, research has found.

It is far from being a “safe” drug and no one under the age of 30 should ever use it, experts said.

People who had only used cannabis once or twice a week for a matter of months were found to have changes in the brain that govern emotion, motivation and addiction.

Researchers from Harvard Medical School in America carried out detailed 3D scans on the brains of students who used cannabis casually and were not addicted and compared them with those who had never used it.

Two major sections of the brain were found to be affected.

The scientists found that the more cannabis the 40 subjects had used, the greater the abnormalities.

Around 10 million people in Britain, almost a third of the population, have used illegal drugs, with cannabis the most popular. The research author, Dr Hans Breiter, professor of psychiatry and behavioural sciences at Northwestern University Feinberg School of Medicine, said: “This study raises a strong challenge to the idea that casual marijuana use isn’t associated with bad consequences. Some people only used marijuana to get high once or twice a week.

“People think a little recreational use shouldn’t cause a problem, if someone is doing OK with work or school. Our data directly says this is not the case.

[...]Mark Winstanley, chief executive of Rethink Mental Illness, said: “For too long cannabis has been seen as a safe drug, but as this study suggests, it can have a really serious impact on your mental health.

“Research also shows that when people smoke cannabis before the age of 15, it quadruples their chance of developing psychosis. But very few people are aware of the risks involved.”

I troubled by this study because I know people who act as if smoking marijuana were as much a right as free speech.

What I would really like to see is that people who insist on engaging in irresponsible behaviors then go on bear the consequences of that behavior. The problem is that it’s not only these people who are affected, it’s the innocent people around them. There are the innocent victims of car accidents or theft or the children who suffer because their parents want to “alter their brains”. Those are the people I am worried about.

New study: teen pot use could hurt brain and memory

NBC News reports.

Excerpt:

Teenage pot smokers could be damaging brain structures critical to memory and reasoning, according to new research that found changes in the brains of heavy users.

Research released Monday in the journal Schizophrenia Bulletin showed the brains of young heavy marijuana users were altered in so-called sub-cortical regions — primitive structures that are part of the memory and reasoning circuits. And young people with such alterations performed worse on memory tests than non-using controls, despite the fact that the heavy users had not indulged for more than two years, on average, before the testing.

“We see that adolescents are at a very vulnerable stage neurodevelopmentally,” said Matthew Smith, who led the research team at Northwestern University Feinberg School of Medicine in Chicago. “And if you throw stuff into the brain that’s not supposed to be there, there are long-term implications for their development.”

The portion of people ages 12 to 17 who used marijuana during the past month fell to 9.5 percent last year from almost 12 percent in 2002, according to the latest figures from the government’s Substance Abuse and Mental Health Services Administration. But that still represents millions of adolescents and teenagers — and the legalization of marijuana has raised the specter that underage people will have easier access.

Adults who smoked pot regularly as teens were shown to have “neuropsychological decline” and “more cognitive problems” than non-users in a study last year in the Proceedings of the National Academy of Sciences (PNAS). This was true even if users stopped using long before the study.

I think these papers are useful when talking to young people about drugs. You don’t want it to be a situation where you are ordering them around based on nothing more than YOUR needs and YOUR beliefs. Then it turns into a head-butting contest, and you can’t watch them all the time. A better alternative is to produce the studies that show the real effects and then ask them what they have on their side. If they are going to rebel anyway, at least you have tried to persuade them rather than control them, and that’s good parenting.

Study: brain of child neglected by mother is smaller and underdeveloped

Dina sent me this article from the UK Daily Mail.

Here is the scan:

Brain scans of 3-year old children: normal vs neglected

Brain scans of 3-year old children: normal vs neglected

Excerpt:

Both of these images are brain scans of a two three-year-old children, but the brain on the left is considerably larger, has fewer spots and less dark areas, compared to the one on the right.

According to neurologists this sizeable difference has one primary cause – the way each child was treated by their mothers.

The child with the larger and more fully developed brain was looked after by its mother – she was constantly responsive to her baby, reported The Sunday Telegraph.

But the child with the shrunken brain was the victim of severe neglect and abuse.

According to research reported by the newspaper, the brain on the right worryingly lacks some of the most fundamental areas present in the image on the left.

The consequences of these deficits are pronounced – the child on the left with the larger brain will be more intelligent and more likely to develop the social ability to empathise with others.

But in contrast, the child with the shrunken brain will be more likely to become addicted to drugs and involved in violent crimes, much more likely to be unemployed and to be dependent on state benefits.

The child is also more likely to develop mental and other serious health problems.

Professor Allan Schore, of UCLA, told The Sunday Telegraph that if a baby is not treated properly in the first two years of life, it can have a fundamental impact on development.

He pointed out that the genes for several aspects of brain function, including intelligence, cannot function.

[...]The study correlates with research released earlier this year that found that children who are given love and affection from their mothers early in life are smarter with a better ability to learn.

The study by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, found school-aged children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress.

The research was the first to show that changes in this critical region of children’s brain anatomy are linked to a mother’s nurturing, Neurosciencenews.com reports.

The research is published online in the Proceedings of the National Academy of Sciences Early Edition.

Lead author Joan L. Luby, MD, professor of child psychiatry, said the study reinforces how important nurturing parents are to a child’s development.

I have a very good feminist non-Christian friend who sometimes comments here. I once asked her about marriage and she said that her skills would be wasting on raising children. I explained to her my view that a mother needs to stay at home with the children, and that is more important work. I expect my future wife to read all kinds of books on child care and to give the child attention, nutrition, exercise and play so that the child will grow up to be an effective Christian. Maybe I need to be clear. I am not going to spend hundreds of thousands per child with just any woman. I need a woman who can produce influential and effective Christians who will engage in the public square. And we do not entrust that job to just anyone – we want a Michele Bachmann or a Jennifer Roback Morse. Professional women who are willing to be stay-at-home moms when it’s necessary to do that.

I expect the woman I marry (if I marry) to have a college degree, and preferably a graduate degree, and a couple of years of employment. Then she has to stay home and invest in those children through the first five years at least. After that she can stay home or work as much as she thinks is beneficial to the family goals of impacting the university, the church and the public square – as well as continuing to raise those children. It’s not a waste of her talent to make the next William Lane Craig, the next Marsha Blackburn, the next Doug Axe, or the next Edith Jones.

New study: breast cancer rates in China skyrocketed because of one-child policy

 

Life Site News reports. (H/T WGB)

Excerpt:

Pro-abortion advocates have relentlessly denied a link between abortion and breast cancer, but a new study has emerged from China that seems to show that such a link not only exists, but that the risk rises with each abortion a woman has.

Dr. Joel Brind, professor of endocrinology at Baruch College, City University of New York and a director at the Breast Cancer Prevention Institute, called the findings a “real game changer” for deniers of the so-called ABC link.

The study, titled “A meta-analysis of the association between induced abortion and breast cancer risk among Chinese females” was published this week in Cancer Causes and Control, a peer-reviewed international cancer journal.

[...]The researchers say they were initially puzzled by their findings, stating that Chinese women “historically” have had lower rates of breast cancer compared to women from western countries such as the US.

They found, however, that incidences of breast cancer in China increased at an “alarming rate” over the past two decades, corresponding with the rise of the Chinese Communist Party’s one-child policy.

[...]The overall risk of developing breast cancer among women having only one abortion increased by 44 percent.

Calling it the “dose-response relationship” researchers also found that the risk of breast cancer increased as the number of abortions increased. Two abortions increased the risk by 76 percent, three by 89 percent.

“In summary, the most important implication of this study is that IA was significantly associated with an increased risk of breast cancer among Chinese females, and the risk of breast cancer increases as the number of IA increases,” concluded the researchers.

IA means “induced abortion”.

More:

The researchers called their findings “consistent” with those of Dr. Brind, who found in a 1996 meta-analysis that women had a 30 percent greater chance of developing breast cancer after aborting their child.

“Not only does [the study] validate the earlier findings from 1996, but its findings are even stronger,” Brind told LifeSiteNews.com.

[...]The Chinese research follows on the heels of two similar studies earlier this year. One study published in the IndianJournal of Community Medicine in May found a 6-fold greater risk of breast cancer among Indian women with a history of induced abortion when compared to the women with no such history. A similar study from Bangladesh published in the Journal of the Dhaka Medical Collegein April found that women with a history of induced abortion had a 20-fold increase in likelihood of developing breast cancer when compared to women with no such history.

In a report last month, Brind called the findings of the two studies “of the sort of magnitude that has typified the link between cigarettes and lung cancer.”

Here’s the results and conclusion from the actual paper:

Results

A total of 36 articles (two cohort studies and 34 case–control studies) covering 14 provinces in China were included in this review. Compared to people without any history of IA, an increased risk of breast cancer was observed among females who had at least one IA (OR = 1.44, 95 % CI 1.29–1.59, I 2 = 82.6 %, p < 0.001, n = 34). No significant publication bias was found among the included studies (Egger test,p = 0.176). The risk increased to 1.76 (95 % CI 1.39–2.22) and 1.89 (95 % CI 1.40–2.55) for people who had at least two IAs and at least three IAs, respectively. Subgroup analyses showed similar results to the primary results. Meta-regression analysis of the included studies found that the association between IA and breast cancer risk attenuated with increasing percent of IA in the control group (β = −0.022,p < 0.001).

Conclusion

IA is significantly associated with an increased risk of breast cancer among Chinese females, and the risk of breast cancer increases as the number of IA increases. If IA were to be confirmed as a risk factor for breast cancer, high rates of IA in China may contribute to increasing breast cancer rates.

Gives a whole new meaning to the phrase “war on women”, especially when you couple it with sex-selection abortion, which pro-abortion people favor. But I have to caution everyone about using studies like this as your whole case against abortion.

Pro-life debater Scott Klusendorf explains:

First, I think it’s wrong when we make how abortion impacts women our primary message. There is a place for that being a secondary message, but it should never be our primary message. Abortion is wrong not because it adversely affects women. It’s primarily wrong because it intentionally takes the life of a defenseless human being. We’ve got to keep our focus clear on that.

I’ve summarized some of the previous studies on abortion/contraception in this recent post.

Study finds that attitude of gratitude has many health benefits

From the Harvard Mental Health Newsletter.

Excerpt:

Two psychologists, Dr. Robert A. Emmons of the University of California, Davis, and Dr. Michael E. McCullough of the University of Miami, have done much of the research on gratitude. In one study, they asked all participants to write a few sentences each week, focusing on particular topics.

One group wrote about things they were grateful for that had occurred during the week. A second group wrote about daily irritations or things that had displeased them, and the third wrote about events that had affected them (with no emphasis on them being positive or negative). After 10 weeks, those who wrote about gratitude were more optimistic and felt better about their lives. Surprisingly, they also exercised more and had fewer visits to physicians than those who focused on sources of aggravation.

Another leading researcher in this field, Dr. Martin E. P. Seligman, a psychologist at the University of Pennsylvania, tested the impact of various positive psychology interventions on 411 people, each compared with a control assignment of writing about early memories. When their week’s assignment was to write and personally deliver a letter of gratitude to someone who had never been properly thanked for his or her kindness, participants immediately exhibited a huge increase in happiness scores. This impact was greater than that from any other intervention, with benefits lasting for a month.

Of course, studies such as this one cannot prove cause and effect. But most of the studies published on this topic support an association between gratitude and an individual’s well-being.

Other studies have looked at how gratitude can improve relationships. For example, a study of couples found that individuals who took time to express gratitude for their partner not only felt more positive toward the other person but also felt more comfortable expressing concerns about their relationship.

Managers who remember to say “thank you” to people who work for them may find that those employees feel motivated to work harder. Researchers at the Wharton School at the University of Pennsylvania randomly divided university fund-raisers into two groups. One group made phone calls to solicit alumni donations in the same way they always had. The second group — assigned to work on a different day — received a pep talk from the director of annual giving, who told the fund-raisers she was grateful for their efforts. During the following week, the university employees who heard her message of gratitude made 50% more fund-raising calls than those who did not.

My editor Mary writes: There is a health bonus to thankfulness but health isn’t why we should be thankful. We should be thankful because we are the recipients of many good things and it is appropriate under such circumstances to express gratitude. It is also the overflow of a heart made happy by the generosity of another.

To help us be thankful, here is a famous Thanksgiving day proclamation.

Here it is:

PRESIDENTIAL THANKSGIVING PROCLAMATIONS

1789-1815 : George Washington, John Adams, James Madison

THANKSGIVING DAY 1789

BY THE PRESIDENT OF THE UNITED STATES OF AMERICA – A PROCLAMATION

Whereas it is the duty of all Nations to acknowledge the providence of almighty God, to obey his will, to be grateful for his benefits, and humbly to implore his protection and favor – and Whereas both Houses of Congress have by their joint Committee requested me “to recommend to the People of the United States a day of public thanksgiving and prayer to be observed by acknowledging with grateful hearts the many signal favors of Almighty God, especially by affording them an opportunity peaceably to establish a form of government for their safety and happiness.”

Now therefore I do recommend and assign Thursday the 26th day of November next to be devoted by the People of these States to the service of that great and glorious Being, who is the beneficent Author of all the good that was, that is, or that will be – That we may then all unite in rendering unto him our sincere and humble thanks – for his kind care and protection of the People of this country previous to their becoming a Nation – for the signal and manifold mercies, and the favorable interpositions of his providence, which we experienced in the course and conclusion of the late war –for the great degree of tranquillity, union, and plenty, which we have since enjoyed – for the peaceable and rational manner in which we have been enabled to establish constitutions of government for our safety and happiness, and particularly the national One now lately instituted, for the civil and religious liberty with which we are blessed, and the means we have of acquiring and diffusing useful knowledge; and in general for all the great and various favors which he hath been pleased to confer upon us.

And also that we may then unite in most humbly offering our prayers and supplications to the great Lord and Ruler of Nations and beseech him to pardon our national and other transgressions – to enable us all, whether in public or private stations, to perform our several and relative duties properly and punctually – to render our national government a blessing to all the People, by constantly being a government of wise, just, and constitutional laws, discreetly and faithfully executed and obeyed – to protect and guide all Sovereigns and Nations (especially such as have shewn kindness unto us) and to bless them with good government, peace, and concord – To promote the knowledge and practice of true religion and virtue, and the increase of science among them and Us – and generally to grant unto all mankind such a degree of temporal prosperity as he alone knows to be best.

Given under my hand at the City of New York the third day of October in the year of our Lord 1789.

(signed) G. Washington

That’s from George Washington.

Happy Thanksgiving Day!
