R48.0: Dyslexia and alexia

You are having reading problems which you did not use to have. With these types of reading problems, it may be that you are unable to understand the meaning of individual words or letters. This can cause the partial or complete loss of your ability to read. You can have this type of reading problem even when you have previously learned to write and read.

You can have reading problems if you have damaged certain parts of your brain. There are different reasons why parts of the brain might be damaged. One reason, for example, may be a head injury. Damage can also occur if parts of the brain are not properly supplied with blood in the event of a stroke. Parts of the brain can also get damaged if an unusual amount of tissue has grown in the brain. Tissue growths like these can be benign or malignant.
