Scientists believe that they might have found a reason why boys are three times more likely to be diagnosed with autism and ADHD Dan Girls.
Researchers from the University of Rochester have suggested that boys are more vulnerable to environmental stressors such as toxic ‘forever chemicals’ as their brains develop.
It is believed that these chemicals warp brain signals, which causes long -term behavioral changes in boys, such as social fear, difficulties to sit still and find it difficult to follow instructions.
Found in everything, of plastic bottles, clothing and even drinking water, these chemicals can take thousands of years to break down and be linked to cancer, infertility and birth defects.
In the current study, the scientists have mentioned a specific ‘Forever Chemical’, known as PFHXA, which is used in paper food packaging and stain -resistant substances.
Researchers say that it can cause anxious behavior that is seen in autism and ADHD, but strangely enough, usually in boys.
They went one study That included exposing baby mice through their mother to the toxin.
The mother mouse received a grinding treat that was treated with PFHXA during pregnancy and while she took care of her offspring.
Researchers said their findings were ‘worrying’, since these chemicals are considered a safer alternative to Legacy Forever Chemicals
PFAS is a common contamination in many household items, from cooking utensils to hamburger wraps. It can remain in the environment and the human tissue for years, even for decades, before it is cleaned up
The administration of the substance in this way meant that the baby mice were exposed to the toxin both in the embryonic and in the pregnancy phase, through her blood and after birth through her milk.
The scientists discovered that the male baby mice showed alarming development changes, including a decrease in activity levels, increased fear and memory problems.
It is important that researchers have not observed the same behavioral changes in the female baby mice.
Even years after the mice were exposed to the chemical for the first time, they still showed behavioral patterns associated with the disorders, which suggests that forever the exposure to chemicals could have long -term effects on the brain.
Professor Elizabeth Plunk, first author of the study and expert in environmental medicine, described the findings as ‘concerning’.
Writing in the European Journal of Neuroscience said researchers: “Although these effects were mild, finding behavioral effects only thought of many neurological disorders that are a male biased in men.”
“Understanding the impact of PFHXA on the developing brain is crucial in proposing regulations around this chemical,” Prof. Plunk added.
The researchers hope that this will be the first of many studies to investigate the harmful effects of PFHXA on the brain – with a renewed focus on the brain areas responsible for movement, memory and emotions.
The findings come in the midst of increasing concern about an increase in ADHD diagnoses – with an estimated 2.5 million people in England who now live with the attention deficit disorder, according to the NHS.
ADHD and autism have long been considered neurological developmental disorders that are a male biased
ADHD is a neurological disorder that influences concentration, impulse control and activity levels.
Common symptoms are restlessness, distractability, forgetfulness, difficulty following instructions or managing time and making impulsive decisions.
Similarly, civil servants have warned that the NHS is ‘overwhelmed’ by the rising autism figures, while 200,000 people are waiting for an assessment in England according to the latest figures.
Autism is a spectrum disorder that influences how people communicate and work on each other.
According to the World Health Organization, about one in 100 children around the world have the condition.
Autistic children can prevent eye contact and not respond to their name that is called, in addition to other symptoms.
Autism is not a disease and people have it from the moment they are born, although it might only be seen in childhood and sometimes much later.
In the past, it has been assumed that autism and ADHD tend to influence more boys than girls and that the disorders are somehow ‘male biased’.
But experts have warned that this can be because boys are referred more often and get a diagnosis – because more symptoms are pronounced – instead of a genetic predisposition.
For example, the NHS notes that autistic girls can hide some signs of autism by copying how other children behave and play.
But anyway, researchers are now afraid that forever chemicals can contribute to the Golf forever, where experts warn earlier this year that the regulation of the UK of the toxic element is too lax.
PFAs can be found in hundreds of daily products because of their sustainability.
But last year an overview of 500 studies showed that they were linked to ‘serious health implications’, including weakening the immune system and being a factor in the diagnosis of cancer.
Now the Environment -Audit Committee (EAC) has been established to give the government to the government by the end of the year about whether the UK should introduce stricter guidelines.
