Aphasia is a condition causing sufferers to struggle with communication. It is most common in older adults, particularly those who have had a stroke or head injury. Aphasia can come on slowly as a result of a brain tumor, an infection in the brain, a neurological disorder such as epilepsy, or a degenerative disorder such as dementia. It doesn't affect intelligence, but aphasia impairs the ability to use and understand language, both verbal and written. Many sufferers also struggle with understanding numbers. Those with aphasia may have difficulty talking, listening, reading, or writing. The level of disability depends on the area of the brain affected and the severity of the damage. An estimated 30-40 percent of stroke patients suffer from aphasia.

With mild aphasia, the victim may be able to converse but struggle with finding the right word to use. With global aphasia, the most severe form of the condition, the victim may not be able to speak, understand spoken words, read, or write. The primary treatment for aphasia is speech therapy, which typically focuses on relearning and practicing language skills or developing other means of communication.
