Since dyslexia is inherited, any adult who has dyslexia should watch for it in their children.

But adults with only mild or moderate dyslexia may not know they have it because they were never tested for it. But they will recognize these classic warning signs.

Lifelong trouble with spelling is one classic warning sign, as this college graduate shared:

Before the invention of the computer and “spell check,” it would take me forever to write a paper. I NEVER wrote letters to friends.

When I asked my mother how to spell a word, she would tell me to go look it up. How the heck can you look up a word if you don’t know how to spell it? I never did understand that. But my mother was a 1952 spelling bee champion, so she had no understanding of my difficulty.

I would spend HOURS going through all of the G’s trying to find the right spelling of jaguar.

Then an English teacher in college took me aside and asked, “Alice, you can’t spell, can you?” I sheepishly admitted I could not. He then asked me how I would spell jaguar. I replied that I wasn’t sure. He asked me if I could spell cat. I said yes. He then handed me a thesaurus and told me to look up cat. And there, under cat, was jaguar.

He then told me he never again wanted me to hand in a paper that was “dumbed down” because I couldn’t spell a word. He was the one who started the ball rolling to get me tested for dyslexia. I was 20 years old and in college.

Although it took forever to write papers, even with a thesaurus, I did get a college degree.

Another classic warning sign is being a very slow reader and having to guess to figure out the longer words – as this man shared:

At 78, I still struggle with dyslexia. Growing up in Tennessee in the 30’s and 40’s, I was viewed as dumb or lazy.

I may not seem as bad as others because I learned how to cheat, and how to avoid English and other courses that required lots of reading or writing. So I made good grades in college – graduating in the top 20% of my engineering class, and then getting an MBA.

But reading is still a lot of work.

And if you are a slow reader with terrible spelling, and you are also unable to master a foreign language, the odds are pretty high that you do have dyslexia – as this woman shared:

My brother’s kindergarten teacher suspected he might have dyslexia, but it took 2 years before he was diagnosed with severe dyslexia.

When I was 12, I attended a Susan Barton presentation on dyslexia with my parents. During her lecture, I realized I was also dyslexic – but I did not struggle as much as my brother. I was just a slow reader and a terrible speller.

It was not until I had to take a foreign language class in college, and failed every language I tried, that my parents finally realized I might also have dyslexia, and had me tested.

If you know or suspect that you have dyslexia, please watch for it in your children – because it is an inherited condition. Not all of them will have it, but about half of them will.
