Aphasia, a communication disorder, develops after injury or damage to the area of the brain that processes language and communication. It can appear after a head injury , stroke, infection, or as a result of problems and conditions such as a brain tumor or neurological diseases such as Alzheimer’s and dementia . People with aphasia have difficulty understanding and expressing language. Aphasia can manifest in both spoken and written forms —a person living with it may have a hard time speaking and understanding spoken words. They may also have difficulty with reading and writing words. Loved ones and others who encounter someone with aphasia should keep in mind that it is a communication disorder that does not necessarily affect someone's intelligence or cognitive abilities.
Aphasia can profoundly affect a person’s quality of life. The condition's effects vary widely and depend on the severity of the damage and the area of the brain affected. It is not an uncommon neurocognitive problem; 25 to 40 percent of people who survive a stroke experience aphasia. A stroke is a common precursor for aphasia —when blood flow to the brain is interrupted, it can lead to damage to brain areas that process language.
Aphasia can occur across age brackets, but it is more likely to affect older adults because of problems like stroke and neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
Global aphasia is a severe type of aphasia, in which multiple language areas of the brain have been injured and affected—perhaps by a stroke or brain injury. People with global aphasia have impaired comprehension of single words, full sentences, and whole conversations and so they may understand very little that is relayed to them.
