Identifying Learning Problems

Reading, writing, and math are the building blocks of learning. Mastering these subjects early on can affect many areas of life, including school, work, and even overall health. It’s normal to make mistakes and even struggle a little when learning new things. But repeated, long-lasting problems may be a sign of a learning disability.

Learning disabilities aren’t related to how smart a child is. They’re caused by differences in the brain that are present from birth, or shortly after. These differences affect how the brain handles information and can create difficulties with reading, writing, and math.

“Typically, in the first few years of elementary school, some children, in spite of adequate instruction, have a hard time and can’t master the skills of reading and writing as efficiently as their peers,” says Dr. Benedetto Vitiello, a child mental health expert at NIH. “So the issue is usually brought up as a learning problem.”

In general, the earlier a learning disability is recognized and addressed, the greater the likelihood for success in school and later in life. “Initial screening and then ongoing monitoring of children’s performance is important for being able to tell quickly when they start to struggle,” explains Dr. Brett Miller, a reading and writing disabilities expert at NIH. “If you’re not actively looking for it, you can miss opportunities to intervene early.”

Each learning disability has its own signs. A child with a reading disability may be a poor speller or have trouble reading quickly or recognizing common words. A child with a writing disability may write very slowly, have poor handwriting, or have trouble expressing ideas in writing and organizing text. A math disability can make it hard for a child to understand basic math concepts (like multiplication), make change in cash transactions, or do math-related word problems.

Learning difficulties can affect more than school performance. If not addressed, they can also affect health. A learning disability can make it hard to understand written health information, follow a doctor’s directions, or take the proper amount of medication at the right times. Learning disabilities can also lead to a poor understanding of the benefits of healthy behaviors, such as exercise, and of health risks, such as obesity. This lack of knowledge can result in unhealthy behaviors and increased risk of disease.

Not all struggling learners have a disability. Many factors affect a person’s ability to learn. Some students may learn more slowly or need more practice than their classmates. Poor vision or hearing can cause a child to miss what’s being taught. Poor nutrition or exposure to toxins early in life can also contribute to learning difficulties.

If a child is struggling in school, parents or teachers can request an evaluation for a learning disability. The U.S. Individuals with Disabilities Education Improvement Act requires that public schools provide free special education support to children, including children with specific learning disabilities, who need such services. To qualify for these services, a child must be evaluated by the school and meet specific federal and state requirements. An evaluation may include a medical exam, a discussion of family history, and intellectual and school performance testing.

Many people with learning disabilities can develop strategies to cope with their disorder. A teacher or other learning specialist can help kids learn skills that build on their strengths to counter-balance their weaknesses. Educators may provide special teaching methods, make changes to the classroom, or use technologies that can assist a child’s learning needs.

A child with a learning disability may also struggle with low self-esteem, lack of confidence, and frustration. In the case of a math learning disability, math anxiety may play a role in worsening math abilities. A counselor can help children use coping skills and build healthy attitudes about their ability to learn.

“If appropriate interventionsActions taken to prevent or treat a disorder or to improve health in other ways. are provided, many of these challenges can be minimized,” explains Dr. Kathy Mann Koepke, a math learning disability expert at NIH. “Parents and teachers should be aware that their own words and behavior around learning and doing math are implicitly learned by the young people around them and may lessen or worsen math anxiety.”

“We often talk about these conditions in isolation, but some people have more than one challenge,” Miller says. Sometimes children with learning disabilities have another learning disorder or other condition, such as attention deficit hyperactivity disorder (ADHD).

“ADHD can be confused with a learning problem,” Vitiello says. ADHD makes it difficult for a child to pay attention, stay focused, organize information, and finish tasks. This can interfere with schoolwork, home life, and friendships. But ADHD is not considered a learning disability. It requires its own treatments, which may include behavior therapy and medications.

“Parents play an important role in treatment, especially for children in elementary school,” Vitiello says. Medications and behavioral interventions are often delivered
at home. Teachers can usually advise parents on how to help kids at home, such as by scheduling appropriate amounts of time for learning-related activities. Parents can also help by minimizing distractions and encouraging kids to stay on task, such as when doing homework. Effective intervention requires consistency and a partnership between school and home.

Many complex factors can contribute to development of learning disabilities. Learning disorders tend to run in families. Home, family, and daily life also
have a strong effect on a child’s ability to learn starting from a very early age. Parents can help their children develop skills and build knowledge during the first few
years of life that will support later learning.

“Early exposure to a rich environment is important for brain development,” Mann Koepke says. Engage your child in different learning activities from the start. Before they’re even speaking, kids are learning. “Even if it’s just listening and watching as you talk about what you’re doing in your daily tasks,” she says.

Point out and talk with children about the names, colors, shapes, sizes, and numbers of objects in their environment. Try to use comparison words like “more than” or “less than.” This will help teach your child about the relationships between things, which is important for learning math concepts, says Mann Koepke. Even basic things, like getting enough sleep and eating a healthy diet, can help children’s brain development and their ability to learn.

NIH is continuing to invest in research centers that study learning challenges and their treatments, with a special focus on understudied and high-risk groups.

Although there are no “cures,” early interventions offer essential learning tools and strategies to help lessen the effects of learning disabilities. With support from caregivers, educators, and health providers, people with learning disabilities can be successful at school, work, and in their personal lives.

Vaccines Protect Us All

We share more than food and culture within our homes and communities. We can also spread disease. Luckily, we live in a time when vaccines can protect us from many of the most serious illnesses. Staying current on your shots helps you—and your neighbors—avoid getting and spreading disease.

Vaccines have led to large reductions in illness and death for both kids and adults, says Dr. David M. Koelle, a vaccine expert at the University of Washington in Seattle. One study estimated that, among U.S. children born from 1994 to 2013, vaccines will prevent about 322 million illnesses, 21 million hospitalizations, and 732,000 deaths.

Vaccines harness your immune systemA collection of specialized cells and organs that protect the body against infectious diseases.’s natural ability to detect and destroy disease-causing germs and then “remember” the best way to fight these germs in the future. Vaccination, or immunization, has completely eliminated naturally occurring smallpox worldwide—to the point that we no longer need to get shots against this fast-spreading, deadly disease. Polio has been eliminated in the U.S. and most other nations as well, thanks to immunizations. Poliovirus can affect the brain and spinal cord, leaving people unable to move their arms or legs, or sometimes unable to breathe.

“These childhood diseases used to be dreaded problems that would kill or paralyze children,” says Koelle. “In the 1950s, it was a common occurrence for kids to be fine in the spring, get polio over the summer, and then have to go back to school in the fall no longer able to walk.”

Experts recommend that healthy children and teens get shots against 16 diseases (see Wise Choices box). With these shots, many disabling or life-threatening illnesses have significantly declined in the U.S., including measles, rubella, and whooping cough. But, unlike smallpox, these disease-causing germs, or pathogens, are still causing infections around the world.

“These days, the risks of not being vaccinated in a developed country, like the United States, may seem superficially safe because of low rates of infection due to vaccination and other advances in public health,” Koelle says. “But we live in an era of international travel where we can be exposed to mobile pathogens.” So even if you don’t travel, a neighbor or classmate could go overseas and bring the disease back to your area.

“When the rates of vaccination drop, there can be a resurgence of the disease,” explains Dr. Saad Omer, a global health researcher at Emory University in Atlanta. For instance, measles was completely eliminated in the U.S. in 2000. But since then, thousands of cases have occurred, mostly related to travel.

Omer and colleagues examined U.S. reports on measles outbreaks since 2000. “We found that measles cases have occurred mostly in those who are not vaccinated and in communities that have lower rates of vaccination. And that’s true for many vaccine-preventable diseases,” he says. Most of the unvaccinated cases were those who chose not to be vaccinated or not have their children vaccinated for non-medical reasons.

When enough people are vaccinated, the entire community gains protection from the disease. This is called community immunity. It helps to stop the spread of disease and protects the most vulnerable: newborns, the elderly, and people fighting serious illnesses like cancer. During these times, your immune system is often too weak to fend off disease and may not be strong enough for vaccinations. Avoiding exposure becomes key.

“There’s a huge benefit to all of us getting the recommended vaccines,” explains Dr. Martha Alexander-Miller, an immune system expert at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina. “Number one, vaccines protect you. But they also limit the presence of disease-causing entities that are circulating in the community. So, you’re helping to protect individuals who may not be capable of protecting themselves, for example because they are too young to get vaccinated.”

When expectant moms are vaccinated, immune protection can pass through the placenta to the fetus. “Early on, the baby’s immune system is immature. So there’s a period of vulnerability where disease and death can occur,” Omer explains. “But the mother’s own antibodies—proteins formed by her immune system—can protect the baby.”

Doctors recommend that moms-to-be get both flu and Tdap (tetanus, diphtheria, and whooping cough) shots. A mother’s antibodies can help protect the newborn until they can receive their own vaccinations.

Some vaccines must be given before pregnancy. Rubella, for instance, can cause life-altering birth defects or miscarriage if contracted during pregnancy. There’s no treatment, but the measles, mumps, and rubella (MMR) vaccine offers prevention. Vaccines for many other common diseases that put newborns at risk are being studied.

“We’ve made amazing progress in the development of effective vaccines,” says Alexander-Miller. “Our ability to have such breakthroughs is the end result of very basic research that went on for years and years.” NIH-funded scientists continue to search for new ways to stimulate protection against various diseases.

Koelle studies how our bodies fight herpes viruses. There are eight related herpes viruses, but the body responds differently to each one. So far, we only have vaccines for one: varicella-zoster virus, which causes chickenpox and shingles.

Koelle’s team is comparing how our immune system responds to chickenpox and the herpes simplex viruses, which cause mouth and genital sores. “We’re hoping to harness the success that has been possible with the chickenpox vaccine and see if we can create a vaccine that would work for both chickenpox and shingles and also herpes simplex,” he says.

Researchers are also working to improve existing vaccines. Some vaccines require a series of shots to trigger a strong immune response. The protection of other vaccines can fade over time, so booster shots may be needed. Some, like the flu vaccine, require a shot each year because the virus changes so that the vaccine no longer protects against new strains. So keeping up with the latest flu vaccines is important.

Ask your doctor’s office whether your vaccinations are current. You may also find records of vaccinations at your state health department or schools. If you can’t find your records, ask your doctor if it’s okay to get a vaccine you might have received before.

Most side effects of vaccines are mild, such as a sore arm, headache, or low-grade fever.

“It can be easy to take vaccines for granted, because you’ll never know all the times you would’ve gotten really sick had you not been vaccinated,” says Alexander-Miller.

Help your community keep diseases at bay: Stay up-to-date with vaccines.

Somatic Symptom Disorders Part I: New Terminology for New Concepts

Dr. Jeffrey Staab, Mayo Clinic Psychiatrist, discusses the concepts that led to the development of the new terminology for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). In DSM-4 somatic symptom disorders were defined negatively, by what they were not. Conversely, the DSM-5 emphasizes a couple core somatic symptom disorders and identifies the key features that can help determine the presence of these disorders. The DSM-5 looks to identify patterns of symptoms that can be identified positively, not the absence of a medical explanation or presumption of a psychological conflict. The change in nomenclature is the next step in the ever-evolving definition of these disorders.
