Left-hand and specific Nervous disorder One new study has been published, though researchers and others have acknowledged the potential limitations.
Although about 10% of the people in the world are left-handed, Autism According to an international team of researchers who have analyzed data from more than 200,000, the chances of the feature are 3.5 times higher.
The survey published in the psychological bulletin journal indicates that the left-and mixed hand is often often seen who are diagnosed with schizophrenia, autism and intellectual disability.
The CDC report said
According to psychology experts, mixed-hand refers to a situation where people can use their left hand for a specific task and for the right for others.
It is somewhat different from the use of both hands, which is equal to both hands.
Studies have shown that the left and mixed hand between some specific diagnosis such as schizophrenia, autism and intellectual disability appears more often. (Estock)
“The main acceptance of this study is that the ideal hand preferences (eg, right-hand) are especially involved in psychiatrists and mental states that affect the language system (eg, schizophrenia) or a first age (eg, autism or ADHD), which affects the neurodovelophan (eg, autism or ADHD).
He is a researcher at the Institute of Cognitive Neuroscience, Bocaum, Germany.
“Mutual relationship does not mean effectiveness-and being left-handed does not mean that anyone will develop autism or schizophrenia.”
All neurological conditions do not show the link to the dominant hand of the human.
For example, frustration and discloculia (inability to learn a mathematics) do not show any meaningful differences in hand preferences compared to the control groups, survey showed.
Language factor
Researchers have also determined that “Attopical Hands” may be associated with long -term linguistic symptoms such as stuttering and dyslexia.
“In most people, dominant The direction of their brain Dr. Ernest Lee, a neurologist from the West Tennessee Medical Group, told Fox News Digital that the process of speech, language, logical thought and the priority of the hand is located.
He was not involved in new research.

Murray also said, “People who are left-handed or ambidxtorsus often have no such dominant unilateral brain-the main parts of the Bengali language can be divided into both sides,” said Mor.
The study also examines groups of people who are diagnosed with a specified set of attic handness in the clinical population or by a specified set Health situation Compared to a control population.
It appears that the symptoms of a previous disorder emerged, more frequent researchers saw the left-and mixed-hand events. (Estock)
“We suspected that the left-and-mixed-hand disorder may be associated with the symptoms that are related to the language,” said a press release about the pachaiser research.
“Like a hand -like language, the brain has a very unilateral position, so it is because of the development of both and the development of their disorders.”
Time key
Researchers also considered other factors that could come to play, such as at age where a person can show the symptoms.

It is displayed that the previous one Disorder Raised, more frequent researchers saw the left-and mixed-hand cases.
Researchers assumed that the left-and mixed hand could be associated with diseases that occur very early in life, because the dominant hand is determined at a very young age- perhaps even Before birthThe

The connection can help expert brains organized and how they develop.
The new study comes with potential limitations. According to experts, not all neurological conditions show the dominant hand link. (Estock)
“With a unilateral brain condition such as stroke, patients have the effect of researching when understanding ways to finoration of neurohabelitation finitions, Multiple sclerosis Or injury brain injury, ”said Murray.
Potential restriction
Manhatton -based psychotherapist and author Jonathan Alopart says the research is “interesting”, though he emphasized its limitations.
“Mutual relationship does not mean effectiveness-and left-hand does not mean that anyone will develop autism or schizophrenia,” the Alpart Fox told News Digital that was not involved in this study.
“Intervention is one of the many factors that can be associated with nervous properties and these quest should be carefully explained to avoid unnecessary alarms or stigma” “
The survey has shown that frustration does not show any meaningful differences in hand preferences compared to control groups. (Estock)
Alopart has called for further research to understand the relationship between handness and mental health.
Lead author Pachaiser agrees that the results are “authentic mutual relations”.
He told Fox News Digital, “We have no effective evidence that the development of a mental illness associated with the neurodovelpment changes interference, or whether the interference changes cause any disorder,” he told Fox News Digital.

The researcher says, “ordinary people should never be terrified if their children like to use their left hand,” the researcher says.
“But because of the emergence of mental disorders in the population, it is important to understand better.”
