“While we know babies born severely preterm generally achieve lower cognitive test scores, this is one of the first studies to look at how severely low birth weight impacts executive functioning, such as attention and visual memory, when these babies become young adults,” said study author professor Katri Räikkönen, PhD, of the University of Helsinki in Finland.
For the Helsinki Study of Very Low Birth Weight Adults, 103 adults born with a very low birth weight (less than 3.3 pounds) and 105 adults who weighed more than 3.3 pounds at the time of birth were given tests that measured their thinking skills, including vocabulary, ability to understand words, memory and IQ. Participants were between the ages of 21 and 30.
The study found that adults with very low birth weight scored lower or performed slower in general intelligence, executive functioning and attention and visual memory compared to the adults born at a low to normal weight. For example, those with a very low birth weight scored an average 8.4 points (0.57 standard deviation units) lower on the full IQ test and 0.30-0.54 standard deviation units lower on the executive functioning and attention and memory tests.
Researchers also found those with very low birth weight were more likely to have received remedial education while in school, but there were no differences in their self-reported academic performance.
“Interestingly, average school grades and the number of years of education completed were not affected by low birth weight in our study,” said Räikkönen. “However, our research underscores the importance of a baby’s full development in the womb.”
The study was supported by the Academy of Finland, University of Helsinki, the Finnish Medical Society Duodecim, Medical Society of Finland, the Finnish Foundation for Pediatric Research, the Finnish Special Governmental Subsidy for Health Sciences, the Jalmari and Rauha Ahokas Foundation, the Juho Vainio Foundation, the Emil Aaltonen Foundation, the Novo Nordisk Foundation, The Päivikki and Sakari Sohlberg Foundation, the Signe and Ane Gyllenberg Foundation, the Yrjö Jahnsson Foundation, the Orion-Pharma Foundation, the Sigrid Juselius Foundation, the Finnish National Graduate School of Clinical Investigation, the Wilhelm and Else Stockmann Foundation and the Pediatric Graduate School, University of Helsinki.
The American Academy of Neurology, an association of 24,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson’s disease and multiple sclerosis.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
