Dyslexia is a difficulty with reading or writing that makes it hard for people to see words as meaningful shapes or distinguish between letters. There are different types of dyslexia related to irregular word reading, connecting sounds to symbols, or both deficits combined. Dyslexia is caused by brain defects and genetic factors. Doctors can examine children if parents notice problems reading by age 6-8. Diagnosis involves sensory, psychological, and skills evaluations. Symptoms include letter/number confusion, poor spelling, and issues with sounds. Solutions include specialized teaching methods, assistive technology, extra time for tests, and activities to make learning fun.
