What aphasia is
NIDCD states: “Aphasia is a disorder that results from damage (usually from a stroke or traumatic brain injury) to areas of the brain that are responsible for language.” And: “Aphasia impairs the expression and understanding of language, as well as reading and writing.”
On the progressive form: “In some cases, aphasia will be the first and most noticeable symptom of dementia, rather than memory, behavioral, or movement changes. This is called primary progressive aphasia, or PPA.”
Diagnosis and referral
NIDCD states: “The doctor who treats a person for a brain injury, such as a stroke, may be the first to identify aphasia.” And: “If the doctor suspects aphasia or PPA, the patient should be referred to a speech-language pathologist for a comprehensive examination of the person's communication abilities.”
Treatment
NIDCD states: “Throughout all phases of recovery, speech-language therapy will help patients regain and improve their ability to communicate.” It adds: “Aphasia therapy aims to improve the ability to communicate by helping individuals use their remaining language abilities, restore language abilities as much as possible, and learn other ways of communicating, such as through gestures, pictures, notebooks, and/or electronic devices.”
On recovery over time: “Research has shown that language and communication abilities can continue to improve for many years after the brain injury and are sometimes accompanied by new activity in brain tissue near the damaged area.”
On teletherapy: “Virtual meetings with speech-language pathologists provide patients with the flexibility and convenience of receiving therapy in their homes through a computer.” Practice rules for remote therapy are on telepractice.
On PPA: “Importantly, people with PPA often benefit from speech-language therapy. Thus, referrals to speech-language pathologists for people with PPA should always be made, not only for assistance with diagnosis but also for treatment.”
Family involvement
NIDCD states: “Family involvement is often a crucial component of aphasia treatment because it enables family members to learn the best way to communicate with their loved one. A strong therapy program will include communication partner training as an essential element.” Its list for family members begins with “Participate in therapy sessions.” and includes “Avoid correcting the person's speech.” and “Allow the person plenty of time to talk.”
