Do twins have more learning disabilities?

Moderate and severe learning disabilities are also significantly more common in twins than in singletons, even when corrected for lower birth weight and when those with CP are excluded (9).

What percentage of twins have learning disabilities?

The relationships between genetic, perinatal and social factors and learning disability were also determined. It was found that 12.5% of twins had learning disabilities.

Are twins more likely to be special needs?

Whether it be due to shorter gestation, premature birth, or maternal health issues, twins are at a higher risk of being born with Special Needs (SPNs). For many new parents, special needs often feel like an insurmountable obstacle.

Can identical twins have different learning disabilities?

Twin studies comparing identical and fraternal twins consistently show substantial genetic influence on individual differences in learning abilities such as reading and mathematics, as well as in other cognitive abilities such as spatial ability and memory.

Do twins have higher IQ?

For IQ scores, twins scored 0.09 points lower than non-twins at age 8 and 0.83 points lower at 10. However, twins scored higher at age 12 by 0.14 points. The only significant difference found was at age 10.

What's special about twins?

It's true that multiples can share a special connection that goes beyond that of ordinary siblings. Sometimes they will say or do the same thing at the same time. Some twins relate incredible stories of coincidence, where they think the same thoughts or sense each other's feelings.

Do twins have worse outcomes?

While twins have been subjects in countless studies that try to separate the effects of nature from nurture, a recent study in PLOS ONE is the first to actually look at what being a twin means for life expectancy. Analysis shows that twins have lower mortality rates for both sexes throughout their lifetimes.

Is dyslexia more common in twins?

This is why dyslexia research in identical twins - twins with identical DNA - only have a 55-70% chance of both twins having dyslexia. In other words, dyslexia does have genetic tied, but it is much too complicated of a disorder to be identified by a single gene.

Is it common for twins to have dyslexia?

Researchers who have studied identical twins have found that where one twin is dyslexic, the other will have dyslexia about 55 to 70 percent of the time, depending on the type of dyslexia.

Are twins more likely to have developmental delays?

Conclusions: Healthy twins should be considered at a higher risk for developmental delay. Whether these results are comparable to preterm singletons, or whether there are twin-specific issues involved, should be further investigated in a study that uses a matched singleton control group.

Are twins more likely to have autism?

Several small studies conducted over the last three decades have found that it is much more common for identical twins to be diagnosed with autism than it is for fraternal twins.

Does being a twin affect social skills?

In adolescence, twins were rated by parents as more aggressive. These studies suggest that twins may be at risk for poorer social interactions in early and middle childhood.

Do twins have better social skills?

Twins will have better communication skills and less sibling rivalry than other children, a study shows. 'Multiple' siblings will have closer bonds than siblings of different ages and are likely to be best friends until adulthood, experts say.

How does being a twin affect child development?

Most previous studies reported that twins have lower cognitive ability than singletons. In a very large study of children born in Birmingham, United Kingdom, between 1950 and 1954, twins had a deficit in verbal reasoning scores at age 11 of 4.4 points on average.

Do twins progress slower?

Multiples do tend to be born smaller than single babies. But it's not because their growth rate is necessarily slower — in fact, for twins, it's about the same as any other baby's until about weeks 30 to 32, when they do slow down a tad, since they're competing more for nutrients.

How common is autism in fraternal twins?

Based on data from 192 pairs of twins, the new study found a concordance rate for autism spectrum disorders of 77 percent among identical twin boys and 31 percent among fraternal twin boys.

What gender is more likely to have dyslexia?

Males are diagnosed with dyslexia more frequently than females, even in epidemiological samples. This may be explained by greater variance in males' reading performance.

Do disabilities run in families?

Research shows that risk factors may be present from birth and tend to run in families. In fact, children who have a parent with a learning disability are more likely to develop a learning disability themselves.

Is dyslexia a form of autism?

Although there may be some co-occurrence of autism and dyslexia, these are different disorders and they are not closely linked. Autism is a developmental disorder, while dyslexia is a learning disability, which is a term encompassing various struggles with the learning process.

Do twins have a lower IQ?

On average, twins have lower IQ scores at 7 and 9 years old than singleton children in the same family. In a cohort study, Ronalds and colleagues (p 1306) used data on 9832 singletons and 236 twins born in Aberdeen between 1950 and 1956.

Which parent carries dyslexia gene?

Does it matter more if the father vs the mother has dyslexia? No. A few genes associated with dyslexia are on the X chromosome, and boys are diagnosed with dyslexia much more often than girls^7,8. But there's no reason to think that you're more likely to get dyslexia from one parent over the other.

Which parent passes down dyslexia?

Both mothers and fathers can pass dyslexia on to their children if either parent has it. There is roughly a 50% – 60% chance of a child developing dyslexia if one of their parents has it.

Do twin moms live longer?

Compared with other mothers, women who deliver twins live longer, have more children than expected, bear babies at shorter intervals over a longer time, and are older at their last birth, according to a University of Utah study.

How does being a twin affect your life?

Being a twin may add a few extra years to your life, a new study suggests. Researchers found that identical twins in Denmark tended to live longer than fraternal twins in that country, while both types of twins typically outlived men and women in Denmark who were not twins.

Are birth defects more common in twins?

Birth defects.

Multiples are about twice as likely as singleton babies to have birth defects, including neural tube defects (such as spina bifida), cerebral palsy, congenital heart defects and birth defects that affect the digestive system.
