Specific Learning Disorders
Dysgraphia
Written expression disorder is a condition that makes it hard to express thoughts and ideas in writing. It also affects grammar and punctuation. Learn more about this common type of learning challenge.
When kids and adults have written expression disorder, or a learning disability in writing, it’s hard for them to put their thoughts into writing. They may have great ideas that they can express verbally, but not when they write. Their writing may include many grammar mistakes or misused words.
Struggling with these important skills can make people feel like they’re not as smart as other people. But written expression disorder isn’t related to intelligence. It’s a weakness in a specific area. And it's a lifelong challenge.
Other learning differences like dyslexia and dysgraphia impact writing. But they do it in different ways.
Writing is a process that involves a group of skills. Kids start learning to write early on, and they continue to build those skills over time. So, trouble with written expression can look different at different ages.
There can also be signs that aren’t about specific skills. For example, people might avoid work that involves writing. Or say they don’t have any ideas to write about.
Learn about the signs of written expression disorder at various ages.
Grades K–2
-
Has trouble labeling pictures with a few words (K–1)
-
Often writes sentences that are hard to understand
-
Sometimes gets confused about the differences between stories, opinions, and informational writing
-
Has trouble writing one or two paragraphs about a personal experience
Grades 3–5
-
Still only writes simple sentences, instead of using a variety of sentences to express ideas clearly
-
Drafts without any planning and does little revising
-
Has trouble with organization and content for different forms of writing, like narratives and opinions
Middle school
-
Struggles to plan before writing and then use the plans
-
Focuses mostly on minor errors and corrections of wording when revising
-
Has a hard time writing more complex narratives about people’s experiences
-
Uses the same words over and over again
-
Struggles to write argumentative papers that back up claims or consider other options
High school
-
Tries to write longer, more complex sentences that end up being confusing
-
Comes up with a few ideas when asked to plan, but doesn’t make and follow an organized plan
-
Has trouble finding weaknesses in writing and revising the content and how it’s organized
-
When using sources in writing, has a hard time explaining the ideas from the sources and integrating ideas from multiple sources
-
Writes papers that are missing facts and detail
Adulthood
-
Makes basic grammar mistakes, like missing verbs or incorrect noun-verb agreement
-
Prefers to give spoken directions instead of written ones
-
Uses the same words over and over again
-
Misuses words or uses words with the wrong meaning
-
Writes rambling sentences and repeats ideas
Struggling with these skills can be very frustrating. But there are things that can help make writing easier. Kids and young adults may use assistive technology for writing, including graphic organizers. And adults may be able to get accommodations at work.
Dyscalculia
Dyscalculia is a condition that makes it hard to do math and tasks that involve math. It’s not as well known or as understood as dyslexia. But some experts believe it’s just as common. That means an estimated 5 to 10 percent of people might have dyscalculia.
It’s not clear whether dyscalculia is as common in girls as in boys. Most experts think there’s no difference. (It’s also a myth that boys are better at math than girls.)
There are different terms for dyscalculia. Mathematics learning disability is one. Mathematics learning disorder is another. Some people call it math dyslexia or number dyslexia. This can be misleading. Dyslexia is a challenge with reading. Dyscalculia is a challenge with math.
People don’t outgrow dyscalculia. Kids who have a hard time with math may continue to struggle with it as adults. But there are strategies that can help them improve math skills and manage the challenges.
Difficulty with math happens at all levels. It can be as hard to learn addition as it is to learn algebra. Basic concepts like quantities can also be a challenge.
That’s why dyscalculia can make it hard to do everyday tasks. Cooking, grocery shopping, and getting places on time all involve these basic math skills, which are known as number sense.
Signs & Symptoms
People with dyscalculia can have trouble with math in different ways. Signs may vary from person to person. And they can look different at different ages.
Problems with number sense may show up as early as preschool in some people. In other people, the challenges become clear as math gets more complex in school.
Common signs of dyscalculia include trouble:
-
Grasping the meaning of quantities or concepts like biggest vs. smallest
-
Understanding that the numeral 5 is the same as the word five, and that these both mean five items
-
Remembering math facts in school, like times tables
-
Counting money or making change
-
Estimating time
-
Judging speed or distance
-
Understanding the logic behind math
-
Holding numbers in their head while solving problems
Possible causes of dyscalculia
Researchers don’t know exactly what causes dyscalculia. But they believe it’s at least partly due to differences in how the brain is structured and how it functions.
Here are two possible causes of dyscalculia:
Genes and heredity: Dyscalculia tends to run in families. Research shows that genetics may also play a part in problems with math.
Brain development: Brain imaging studies have shown some differences between people with and without dyscalculia. The differences have to do with how the brain is structured and how it functions in areas that are linked to learning skills.
Researchers aren’t just looking into what causes dyscalculia. They’re also trying to learn if there are strategies that can help “rewire” the brain to make math easier.
