Expressive or receptive aphasia can occur after stroke and impairs one's ability to express or understand language. Reading and writing can be effected as well. Expressive language disorders cause difficulty in articulating or saying words, but there is often good comprehension and understanding of spoken language. Receptive language disorders, on the other hand, cause impairment in one's ability to understand language thus comprehension may be poor. Detailed descriptions of expressive and receptive problems are discussed below.
Wernicke's Aphasia - Stroke victims with this type of receptive language disorder often have great difficulty with understanding speech. Their pattern of speech may sound right, but they often say words or sentences that don't make sense and may not be aware that they are saying the wrong words. Reading and writing are often grossly impaired.
Broca's Aphasia - Speech production is severely limited often to less than four words. The words used frequently make sense, but the stroke patient has great difficulty coming up with the words and does not form complete sentences. For example, the person may say "bathroom" instead of "I need to go to the bathroom". The patient with this type of language disorder may be able to understand speech and be able to read but have difficulty with writing.
Global Aphasia - This is a severe language disorder and is characterized by the stroke victim neither understanding or speaking language. The ability to read and write is also lost. It is a result of extensive damage to the language areas of the brain.

Treatment - Stroke victims with speech difficulties should seek out the assistance of a licensed speech and language pathologist (SLP). A SLP can work with stroke patients to help restore impaired language abilities as much as possible, maximize remaining language function, and learn techniques to compensate for language deficits. Compensatory techniques taught may include using gestures, using pictures, writing, or communication boards or cards. Examples of communication boards and cards that you can purchase on the internet are provided below:
There are computer programs that are used to help treat language disorders. These programs are designed to help improve reading, speech, recall, and comprehension. The computer can help stimulate the stroke victim's vision and hearing at the same time which is beneficial to the recovery process.
