What is aphasia?

It is the disorder of communication that occurs due to damage or injury to the portion of the brain that controls speech. For most people, these are the areas on the left hemisphere of the brain.

People suffering from aphasia have to face a lot of difficulty in understanding conversation, understanding written words as well as problems in writing words, and also using numbers.

Patterns of aphasia

People with aphasia may experence different patterns of weaknesses and strengths.

● Comprehensive aphasia. Also called Broca’s or nonfluent aphasia, people suffering from this pattern of aphasia may understand what others say better than they can speak. Individuals with this pattern struggle to get words out, omit words and speak in very short sentences. These people may say, “Walk park today” or “Want food”.

A hearer can generally understand the meaning. People with this pattern of aphasia are usually aware of their difficulty in communication and can get frustrated. These people may also have right-sided weakness or paralysis.

● Expressive aphasia. Espressive aphasia is also called fluent or Wernicke’s aphasia. People suffering from this aphasia pattern can speak effortlessly and fluently in long, complex sentences which may not make sense or include incorrect, unrecognizable, or unnecessary words. These people generally do not comprehend spoken language well and usually do not realize that others cannot understand them too.

● Global aphasia. Characterized by poor comprehension along with difficulty in forming words and sentences, Global aphasia is caused by extensive damage to the language networks of the brain. Individuals with global aphasia suffer from severe disabilities with expression and comprehension

How is aphasia treated?

The treatment of aphasia depends upon the severity of damage and can be categorized as mild, moderate, or severe . Each will receive specific treatment.

If the brain damage is mild, there is no need for any medical or surgical treatment. Furthermore, we can treat them by providing speech therapy that helps to improve their language or communication skills.

Similarly, individuals suffering from aphasia are more prone to go into depression due to a lack of communication. So they should seek medical treatment as soon as possible.
Currently, some medications are being researched upon for treatment of aphasia. These include medicines that may improve blood flow to the brain, enhance recovery ability of the brain or help replace depleted neurotransmitters (chemicals in the brain). Many drugs, like piracetam and memantine (Namenda), have shown promise in small studies. However, more research is required before such treatments can be recommended.
Moreover, there is no particular drug treatment for aphasia. Therefore, doctors mostly advise some medications for symptomatic treatment.

Complications of aphasia

For a person suffering from aphasia, the condition usually takes a longer period to show signs of improvement, sometimes years to even decades. Complete recovery is not fully achieved. So, people do face problems in their day to day life due to inappropriate communication. It affects their career, day to day activities that tend to make them frustrated and lonely which is a high risk for depression.
