Acquired Dyslexia

Acquired dyslexia (also known as alexia) is when dyslexia (a reading disorder that causes difficulty or inability to read due to altered perception of letters and words) is caused by brain damage (like from an injury or a stroke) and occurs after the sufferer has learned to read. The condition is marked by a range of severity and differing manifestations of the disturbance. This is contrasted with developmental dyslexia which disrupts the learning process and is typically noticed and diagnosed when children are learning to read. Developmental dyslexia is believed to be cause by both environmental and genetic factors.
