Left and definite neurological disorders May go hand in hand, showed a new study, although researchers and others have recognized potential restrictions.
While about 10% of people in the world left, People with autism According to the international group of researchers, 3.5 times more likely to have a rice that analyzed data with more than 200,000 people.
A study published in the journal psychological newsletter showed that on the left and ambiguity are also more often in people who have diagnoses such as schizophrenia, autism and intellectual disability.
Increasing autism speeds now affect 3% of children, the CDC report said
According to psychology experts, mixing refers to a situation in which people can use the left hand for a specific task and right hand for others.
It is a little different from Ambidexterity, which is equal to the use of both hands.
The study found that on the left and ambiguity are more common in people who have certain diagnoses such as schizophrenia, autism and intellectual disability. (Istock)
“The key conclusions of this study are that the changes in the preference in the hands (ie, the right hand) are associated especially with the psychiatric and psychological conditions that affect the linguistic system (such as dyslexia or schizophrenia) or affect neurosity at an early age (for example, autism, autism. Either ADVG), “Leading author Dr. Julian Pacchaiser told Fox News Digital.
He is a researcher at the Cognitive Neurology Institute at Rura Bochum University in Germany.
“The correlation does not mean causal-and not to be left hand does not mean that someone will develop autism or schizophrenia.”
Not all neurological conditions showed a connection with the dominant hand of people.
Depression and Disco (Mathematical training disability), for example), did not show significant difference in hand preference compared to control groups, showed in the study.
Language factor
Researchers also determined that “atypical hand” may be associated with long -term linguistic symptoms such as stuttering and dyslexia.
“Most people are dominant side of their brain Usually the speech, language, logical treatment of thought and preference manually, “said Dr. Ernest Lee Murray, the West Tennese, Fox News Digital Medical Group.
He did not participate in a new study.

“People who are left or ambitious often do not have such a dominant one-sided brain, the key parts of the language can be divided between both sides,” Murray also said.
The study also studied the likelihood of atypical transmission in clinical populations or groups diagnosed health status Compared to the control population.
It seems that the symptoms of the disorder seem to have previously occurred, the more often the researchers saw cases of left and mixed hand. (Istock)
“We suspected that on the left and ambiguity may be associated with disorders whose symptoms are associated with language,” Pacchaiser said in a press release on the study.
“The language, as well as the hand, has a very unilateral place in the brain, therefore, truly, the development of both and their disorders can be associated.”
Terms are key
Researchers have also considered other factors that could go into the game, such as an age at which a person can show symptoms.

It turns out that before Symptoms of disorder It appeared that more often researchers saw cases of left and mixed hand.
Researchers suggested that the left and ambiguity may be associated with diseases that arise very early in life because the dominant hand is determined at a very early age- even even Before birth.

In the womb, the finger of the finger for 10 weeks of pregnancy is strongly linked to which hand will be preferred in later life, they noted.
Communication can help experts potentially understand how organized brains and how they develop.
A new study comes with potential restrictions. According to experts, not all neurological conditions show the connection with the dominant hand of man. (Istock)
“The study has consequences when understanding ways scattered sclerosis Or a traumatic trauma, “Murray said.
Potential restrictions
Jonathan Alpert, a psychotherapist and author based in Manhattan, said the study was “interesting”, although he emphasized his restrictions.
“The correlation does not mean cause and effect- and be a left hand does not mean that someone will develop autism or schizophrenia,” said Alpert, who did not participate in the study, said Fox News Digital.
“Duration is just one of the many factors that can be associated with neurological features, and these conclusions should be interpreted with caution to avoid unnecessary anxiety and stigma.”
The depression did not reveal a significant difference in hand preference compared to the control groups, the study showed. (Istock)
Alpert called for additional research to understand relationships, if any, between pen and mental health.
The lead author Packheiser agreed that the results are “purely correlation”.
‘We have no causal evidence that the development of a mental disorder associated with Language or neurose Causes a change of hands, or whether the changes in the hands cause any disorder, “he said Digital Fox News.

“So, people from the general public should never be disturbed if their child prefers to use the left hand,” the researcher said.
“But given the rise Mental disorders It is important for the population to better understand them. “
