Aphasia is a communication disorder that occurs after language has been developed, usually in adulthood. Not simply a speech disorder, aphasia can affect the ability to comprehend the speech of others, as well as the ability to read and write.

A speech therapist (an expert trained in speech rehabilitation) will work closely with the patient. The main goal of speech therapy is to help the patient communicate. During rehabilitation (rehab) the therapist works to find and increase a patient's strengths. The therapist also tries to improve understanding between patient and family.

Detailed information on hearing loss in babies According to the National Institutes of Health (NIH), nearly 12,000 babies are born each year in the United States with a hearing impairment. It is estimated that serious hearing loss occurs in about one to three of every 1,000 healthy newborns, and in two to four of every 100 babies in newborn intensive care units. Without screening or testing, hearing loss may not be noticed until the baby is more than 1 year old. If hearing loss is not detected until later years, there will not be stimulation of the brain's hearing centers. This can affect the maturation and development of hearing, and can delay speech and language. Social and emotional development and success in school may also be affected.
