Biological Basis For Teenage Mood Swings Found

From http://www.medicalnewstoday.com/healthnews.php?newsid=65035

A new US study has revealed that teenage mood swings may be explained by biological changes in the adolescent brain.

The research is published in the journal Nature Neuroscience.

Mood swings and anxiety, often caused by stress, are well known characteristics of puberty.

A physiologist at the State University of New York, Sheryl Smith, and her research colleagues experimented on female adolescent mice and showed that their brains respond to stress in a different way to adults and pre-pubescent individuals.

Anxiety is regulated by the brains's principal inhibitory neurotransmitter, GABA (gamma-amino-butyric-acid) which counteracts the effect of glutamate, an excitatory neurotransmitter in the brain's limbic system.

Stress causes the release of a steroid known as THP (allopregnanolone) which in adult and pre-pubescent individuals increases the "calming" effect of GABA in the limbic system. However, Smith and her team found that THP had the opposite effect in adolescent mice.

It would appear that THP has two roles, one in the limbic system where it helps to calm things down, and another in the hippocampus where in adolescents it hots things up. The hippocampus is important for emotion regulation.

This paradoxical role of THP, said Smith and her team, is the reason for the adolescent brain behaving differently.

The underlying mechanism appears to be different levels of expression of a type of receptor known as the "alpha4betadelta" GABAA receptor in the hippocampal brain region known as CA1.

In adults and pre-adolescents, the receptors are in low numbers so the overall effect of THP is a calming one.

However, in adolescents, the expression of these receptors is high, so for these individuals the anxiety raising effect of THP in the hippocampus outweighs the calming effect it has in the limbic system.

Smith and her team were able to reverse the puberty effect in the mice by genetically altering the number of receptors.

The net effect is that whatever the teenage person's reaction to stress is likely to be, whether to cry or be angry, it will be "amplified". While to adults it may seem like an overreaction, to the teenager it is the only thing they can do, said the researchers.

This study is thought to be the first to suggest an underlying physiological, as opposed to a behavioural-psychological explanation for teenage mood swing

TREATED BAD BY INSURANCE CARRIER ?

I see injured workers every day. As a treating doctor, daily I am confronted with insurance carriers who deny, dispute, foot drag, and some, act in a way that may constitute "bad faith".

Patients get upset. But, how will things get changed? Patients who are unrepresented by attorneys, patients who cannot afford to hire attorneys specializing in Work Comp, but who are advised by ombudsman, often lose Benefits Review Conferences (BRC) and Contested Claims Hearings (CCH), and, after reading the decisions, I believe these folks ought NOT to have lost, because there is a preponderence of medical opinion in their favor.

Perhaps you alone cannot change the system, but I contend that if ENOUGH weight is brought to bear on the Department of Insurance about perceived wrongdoing by insurance carriers, and enough media people (television stations, radio, newspapers, bloggers) bring the issue to the public attention, there is certainly a stronger possibility that some positive changes will occur.

If no one complains, or not enough complain, the system will get worse and worse and worse.

Perhaps the easiest way to contact the Texas Department of Insurance, Work Comp division, is via e-mail WorkersComp@tdi.state.tx.us .

To write a snail mail letter of complaint :

In probably the only time in history, Dr. John Raymond Baker,DC and the Texas Medical Association are in agreement

There is the old saying about the enemy of my enemy is my friend. I just discovered that I and the TMA are in agreement about something. Both of us agree that Gardasil, also known as the "cervical cancer vaccine" (though that is a misnomer and it is not a vaccine against cervical cancer) should NOT be mandated by the state of Texas.

"Earlier this month, Gov. Rick Perry issued an executive order that made Texas the first state to mandate the vaccine for young girls. Perry said his goal was to protect future generations from cervical cancer, which afflicts 10,000 U.S. women a year.
Perry has been rebuked by social conservatives, who say his promotion of the vaccine condones pre-marital sex, and legislators who say he exceeded his constitutional powers by issuing the executive order.
The Texas Medical Association, too, has said that the vaccine shouldn't be mandated, citing, in part, the high cost of the three-shot regimen, which starts at $360."

We must note that, as cited above, the cost of the three shot regimen STARTS at $360.00.
Now imagine if, as Gov. Perry would have it, every female child in a certain age range, would be mandated to take the shot. Can you say "millions of dollars for Merck". It just so happens, that the same day Gov Perry signed the executive order mandating the Merck medicine be given to girls...his "campaign" received a "contribution" of $5000.00.

Perry says it was just a "coincidence".

Yeah, and light hitting the head of my bed just "coincides" with the sun rising.
