Dyslexia.

Dyslexia, also known as reading disorder, is characterized by trouble with reading despite normal intelligence.
Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads.
The difficulties are involuntary and people with this disorder have a normal desire to learn. People with dyslexia have higher rates of attention deficit hyperactivity disorder (ADHD), developmental language disorders, and difficulties with numbers.

The underlying mechanisms of dyslexia are problems within the brain's language processing.
Problems may include difficulties with summarizing stories, memorization, reading aloud, or learning foreign languages.
People with dyslexia are commonly poor spellers.

Dyslexia often co-occurs with other learning disorders:
• [Dysgraphia]: A disorder involving difficulties with writing or typing, sometimes due to problems with eye–hand coordination; it also can impede direction- or sequence-oriented processes, such as tying knots or carrying out repetitive tasks.
• [Attention deficit hyperactivity disorder (ADHD)]: A disorder characterized by problems sustaining attention, hyperactivity, or acting impulsively. Dyslexia and ADHD commonly occur together.
• [Auditory processing disorder]: A listening disorder that affects the ability to process auditory information.
• [Developmental coordination disorder]: A neurological condition characterized by difficulty in carrying out routine tasks involving balance, fine-motor control, kinesthetic coordination, difficulty in the use of speech sounds, problems with short-term memory, and organization.
