Dyslexia is a learning disability that makes reading difficult. Someone with dyslexia has trouble with the decoding process used to read. Decoding refers to the process of recognizing the sounds in speech and relating them to the letters and words on a page. The part of the brain that is involved with language is affected in someone with dyslexia. Dyslexia is not related to vision or intelligence, and children with this disability most often have good eyesight and normal to above average intelligence.
Addiction, also called substance use disorder, is a behavioral, mental health, and brain disorder caused by abuse of drugs or alcohol. Not everyone who abuses substance will get addicted, but those who do struggle to stop using, continue using in spite of problems it cause, ignores responsibilities or other activities, and ultimately develops tolerance to the drug or alcohol, and withdrawal symptoms when not using.
A child with dyslexia may develop a number of complications, from doing poorly in school to having low self-esteem and struggling to fit in socially. Especially when dyslexia goes unrecognized and untreated, a child is at significant risk for eventually experimenting with drugs or alcohol, abusing substances, and developing a substance use disorder.
