Identified as left-handed Neuropathy Researchers and others have acknowledged potential limitations, but a new study has revealed.
Around 10% of people in the world are left-handed, People with autism According to an international team of researchers who have analyzed data from over 200,000 individuals, they are 3.5 times more likely to have characteristics.
The study, published in the Journal Psychological Bulletin, showed that left-handed and mixtures appear more frequently in people diagnosed with schizophrenia, autism, and intellectual disability.
Rising autism rates currently affect 3% of children, the CDC report says
According to psychology experts, mixed benefits refer to situations where the left hand can be used for a particular task and the right hand for another person.
This is slightly different from ambidexterity. This is an equal use of both hands.
This study showed that left and mixtures appear more frequently in people with specific diagnosis such as schizophrenia, autism, and intellectual disability. (istock)
“The key point of this study is that changes in hand preferences from the usual (i.e. right-handed) are related to psychiatric and psychological conditions that affect the language system (e.g. dyslexia and schizophrenia) or affect early childhood neurodevelopment (e.g. autism, autism). Or ADHD), “Author Dr. Julian Packheiser told Fox News Digital.
He is a researcher at the Institute of Cognitive Neuroscience at Ruhr University Bochum, Germany.
“Correlation does not mean causality. Being left-handed does not mean that someone develops autism or schizophrenia.”
Not all neurological conditions provided links to the dominant hands of people.
Depression and Calclear For example, mathematics learning disorders (mathematics learning disorders) showed no meaningful differences in hand preferences compared to control groups, the study found.
Language factors
The researchers also determined that “atypical handedness” could be associated with long-term language symptoms such as stud sounds and dyslexia.
“For most people, it’s dominant The side of their brain Dr. Earnest Lee Murray, a neurologist at West Tennessee Medical Group, is usually where speech, language, logical thinking processing and hand preferences are located.
He was not involved in new research.

“Left-handed or ambidextrous people often do not have such a dominant unilateral brain. Rather, important parts of language can be split into two sides,” Murray said.
This study also examined the possibility of atypical dominant hands in clinical populations, or groups of people diagnosed with a particular set. Health status Compared to the control population.
The earlier the symptoms of the disorder appeared, the more frequent the researchers saw cases with more mixed left and more mixed. (istock)
“We suspected that left wing and mixing were associated with disorders in which symptoms were language-related,” Packheiser said in a press release on the study.
“Language, like the dominant hand, has a very one-sided position in the brain, so there’s a reason why both and the development of that disorder can be linked.”
Timing is important
The researchers also looked at other factors that could affect, such as the age at which a person could exhibit symptoms.

Previous a Symptoms of the disorder Appearances and more frequently researchers saw cases of left and mixtures.
The researchers hypothesized that, perhaps even more, left-wing and mixed-benefits could be associated with diseases that occur very early, as the dominant hands are determined at very early ages. Prenatal.

In the uterus, putting a thumbs on a 10-week pregnancy is a big link to the hands that prefer later years.
This connection helps experts to potentially understand how the brain is organized and how they develop.
New research has potential limitations. Experts say not all neurological conditions indicate a link to a person’s dominant hand. (istock)
“This study will have an impact when we understand how to fine-tune neurosis in patients with unilateral brain symptoms, such as stroke. Multiple sclerosis Or traumatic brain injury,” Murray said.
Potential limitations
The study highlighted its limitations but said it was “interesting,” said Jonathan Alpert, a Manhattan-based psychotherapist and author.
“Correlation does not mean causality, and being left-handed does not mean that someone develops autism or schizophrenia,” Alpert, who was not involved in the study, told Fox News Digital.
“Hand dominant hand is just one of many factors that may be related to neurological properties. These findings need to be interpreted with caution to avoid unnecessary alarms and stigma.”
Depression showed no meaningful differences in hand preferences compared to controls, the study found. (istock)
Alpert called for further research to understand the relationship between dominant hand and mental health.
Read author Puckheiser agreed that the results were “purely correlated.”
“We have no causal evidence that we develop mental disorders. Language or Neurodevelopment He told Fox News Digital.

“Therefore, individuals from the public should never be wary if a child prefers to use their left hand,” the researchers said.
“However, considering the rise of Mental disorders In the population, it is important to understand them better. ”
