Studies have shown that, although there is no consistency on treatment methodology in literature, there is a strong indication that treatment, in general, has positive outcomes. Therapy for aphasia ranges from increasing functional communication to improving speech accuracy, depending on the persons severity, needs and support of family and friends. Group therapy allows individuals to work on their pragmatic and communication skills with other individuals with aphasia, which are skills that may not often be addressed in individual one-on-one therapy sessions. It can also help increase confidence and social skills in a comfortable setting. : 97 Evidence does not support the use of transcranial direct current stimulation (tDCS) for improving aphasia after stroke. Moderate quality evidence does indicate naming performance improvements for nouns but not verbs using tDCSSpecific treatment techniques include the following:

Copy and recall therapy (CART) –  repetition and recall of targeted words within therapy may strengthen orthographic representations and improve single word reading, writing, and naming
Visual communication therapy (VIC) –  the use of index cards with symbols to represent various components of speech
Visual action therapy (VAT) –  typically treats individuals with global aphasia to train the use of hand gestures for specific items
Functional communication treatment (FCT) –  focuses on improving activities specific to functional tasks, social interaction, and self-expression
Promoting aphasics communicative effectiveness (PACE) –  a means of encouraging normal interaction between people with aphasia and clinicians. In this kind of therapy, the focus is on pragmatic communication rather than treatment itself.
Strokes account for most documented cases of aphasia: 25% to 40% of people who survive a stroke develop aphasia as a result of damage to the language-processing regions of the brain. Aphasia and dysphasia
Technically, dysphasia means impaired language and aphasia means lack of language. There have been calls to use the term aphasia regardless of severity. Reasons for doing so include dysphasia being easily confused with the swallowing disorder dysphagia, consumers and speech pathologists preferring the term aphasia, and many languages other than English using a word similar to aphasia. The term "aphasia" is more commonly used in North America, while "dysphasia" is more frequently used elsewhere. Signs and symptoms
People with aphasia may experience any of the following behaviors due to an acquired brain injury, although some of these symptoms may be due to related or concomitant problems, such as dysarthria or apraxia, and not primarily due to aphasia. Aphasia symptoms can vary based on the location of damage in the brain. Signs and symptoms may or may not be present in individuals with aphasia and may vary in severity and level of disruption to communication. Often those with aphasia may have a difficulty with naming objects, so they might use words such as thing or point at the objects. When asked to name a pencil they may say it is a “thing used to write”.
