What is Aphasia?

Aphasia is a disease that robs you of the desire to communicate. Your ability to speak, write and understand words, both spoken and written, will be impaired.

After a stroke or a brain injury, aphasia usually occurs unexpectedly. But a slow-growing brain tumour or a disorder that causes progressive, permanent damage will also eventually arise from it (degenerative). Aphasia occurrence depends on a variety of factors, including the cause and nature of the injury to the brain.

When the cause has been discussed, speech and language therapy is the primary cure for aphasia. The person with aphasia relearns and practises language skills and learns to communicate in other ways. Members of the family also engage in the process, helping the client connect.

What are the causes of Aphasia?

Brain injury arising from a stroke is the most frequent cause of aphasia-the blockage or rupture of a blood artery in the brain. In areas that regulate expression, lack of blood to the brain contributes to the death or damage of brain cells.

Aphasia may also be caused by brain trauma caused by a major head injury, a tumour, an infection or a degenerative process. In these situations, other types of neurological difficulties, such as memory problems or misunderstanding, typically arise with aphasia.

The word used for language impairment that progresses progressively is primary progressive aphasia. This is attributed to the irreversible degeneration of brain cells found in the networks of expression. This type of aphasia will often advance to a more widespread dementia.

Temporary symptoms of aphasia can happen occasionally. These may be caused by migraines, epilepsy, or a temporary ischemic attack (TIA). A TIA takes place as blood flow to a region of the brain is momentarily blocked. In the near term, people who have had a TIA are at an elevated risk of experiencing a stroke.

What are the types of Aphasia?

Global aphasia

This is the most severe form of aphasia, and is applied to patients who can produce few recognizable words and understand little or no spoken language. Persons with Global Aphasia can neither read nor write. Global aphasia may often be seen immediately after the patient has suffered a stroke and it may rapidly improve if the damage has not been too extensive. However, with greater brain damage, severe and lasting disability may result.

Broca’s aphasia (‘non-fluent aphasia’)

In this form of aphasia, speech output is severely reduced and is limited mainly to short utterances of less than four words. Vocabulary access is limited and the formation of sounds by persons with Broca’s aphasia is often laborious and clumsy. The person may understand speech relatively well and be able to read, but be limited in writing. Broca’s aphasia is often referred to as a ‘non fluent aphasia’ because of the halting and effortful quality of speech.

Mixed non-fluent aphasia

This term is applied to patients who have sparse and effortful speech, resembling severe Broca’s aphasia. However, unlike persons with Broca’s aphasia, they remain limited in their comprehension of speech and do not read or write beyond an elementary level.

Wernicke’s aphasia (‘fluent aphasia’)

In this form of aphasia the ability to grasp the meaning of spoken words is chiefly impaired, while the ease of producing connected speech is not much affected. Therefore Wernicke’s aphasia is referred to as a ‘fluent aphasia.’ However, speech is far from normal. Sentences do not hang together and irrelevant words intrude-sometimes to the point of jargon, in severe cases. Reading and writing are often severely impaired.

Anomic aphasia

This term is applied to persons who are left with a persistent inability to supply the words for the very things they want to talk about-particularly the significant nouns and verbs. As a result their speech, while fluent in grammatical form and output is full of vague circumlocutions and expressions of frustration. They understand speech well, and in most cases, read adequately. Difficulty finding words is as evident in writing as in speech.

Primary Progressive Aphasia

Primary Progressive Aphasia (PPA) is a neurological syndrome in which language capabilities become slowly and progressively impaired. Unlike other forms of aphasia that result from stroke or brain injury, PPA is caused by neurodegenerative diseases, such as Alzheimer’s Disease or Frontotemporal Lobar Degeneration. PPA results from deterioration of brain tissue important for speech and language. Although the first symptoms are problems with speech and language, other problems associated with the underlying disease, such as memory loss, often occur later.

Other varieties

In addition to the foregoing syndromes that are seen repeatedly by speech clinicians, there are many other possible combinations of deficits that do not exactly fit into these categories.Some of the components of a complex aphasia syndrome may also occur in isolation. This may be the case for disorders of reading (alexia) or disorders affecting both reading and writing (alexia and agraphia), following a stroke. Severe impairments of calculation often accompany aphasia, yet in some instances patients retain excellent calculation in spite of the loss of language.

What are the symptoms of Aphasia?

Among the major signs of aphasia are:

  • Talking troubles
  • Struggling to find the correct word or phrase
  • Using weird or inappropriate words in speech
  • Trouble hearing what others are saying or joining discussions
  • Writing sentences that have little meaning or difficulties voicing yourself in writing
  • Talk in brief phrases or sentences
  • Used words being unrecognisable

Aphasia can be extreme or moderate. The person may be able to converse with moderate aphasia, but have difficulty finding the right expression or interpreting complicated conversations. Severe aphasia makes the person less capable of communicating. The person may say nothing and may not take part in any discussion or understand it.

Any person with aphasia has difficulty interpreting what others mean. In specific, difficulties arise when the person is tired or in a busy or noisy environment. Aphasia had little effect on thought skills. But the person may have trouble reading written content and a tough time with handwriting. Some persons have difficulty using numbers or even making basic calculations.

What are the complications of Aphasia?

As contact is so much a part of your life, Aphasia will cause many quality-of-life concerns.

Difficulties with communication can affect your:

  • Job/Profession
  • Relationships
  • Day-to-Day Work
  • Language barriers can result in issues with humiliation, depression and relationships.

How is Aphasia diagnosed?

Imaging tests, such as magnetic resonance imaging (MRI) and computed tomography (CT) may be ordered. These tests identify the cause and areas of the brain that are damaged. Your physician may perform a basic language skills exam in which the patient is asked to carry on a conversation, name objects, answer questions and follow instructions. If your physician suspects aphasia, the patient is usually referred to a speech-language pathologist for a comprehensive exam. This healthcare professional is specially trained in identifying and improving language and communication abilities.

The speech-language pathologist will conduct tests to assess abilities such as grammar, ability to form sounds and letters, understanding (comprehension) of words and sentences, and object knowledge. Tests may involve picture descriptions, using single words to name objects and pictures, matching spoken words to pictures, answering yes/no questions, following directions and other tests.

You’ll also likely undergo tests and informal observations to assess your language skills, such as the ability to:

  • Name common objects
  • Engage in a conversation
  • Understand and use words correctly
  • Answer questions about something read or heard
  • Repeat words and sentences
  • Follow instructions
  • Answer yes-no questions and respond to open-ended questions about common subjects
  • Read and write

What is the treatment for Aphasia?

Tremendous changes arise in the brain following a brain injury, which help it heal. As a consequence, in the first six months, even without medication, individuals with aphasia frequently make drastic changes in their vocabulary and speech skills. But some aphasia persists after this initial healing time in many cases. Speech-language therapy is used in these cases to help people recover their ability to speak.

Analysis has demonstrated that, for several years, language and speech skills can continue to develop and are often followed by new brain tissue activity in the affected region. The cause of brain injury, the region of the brain that was affected and its duration, and the age and fitness of the person are some of the factors that which impact the amount of change.

Aphasia rehabilitation helps to increase the capacity of a person to communicate by encouraging him or her to use the residual abilities of language, recover language competence as far as possible, and develop new ways of communicating, such as gestures, images, or using mobile media. Social counselling works on the individual’s personal interests, while community therapy provides the ability in a small-group environment to use new coping techniques.

For people with aphasia, recent developments have developed new resources. “Virtual” speech pathologists have the versatility and accessibility for patients to get counselling from a device in their homes. For people who have problems using spoken language, the use of speech-generating tools on electronic devices such as tablets may also offer an alternative way to communicate.

Patients with aphasia are increasingly involved in events, such as book clubs, technology classes, and clubs for art and drama. In addition to enhancing their coping skills, such interactions help patients recover their confidence and social self-esteem. In most major cities, stroke clubs, regional support groups created by people who have had a stroke, are available. These clubs may assist a participant and his or her family to respond to the changes in life that follow stroke and aphasia.

Family interaction is also a vital aspect of the care of aphasia and it helps family members to understand the correct way to engage with their loved one.

Members of the family are encouraged to:

  • Where necessary, engage in counselling sessions.
  • Using simple, uncomplicated sentences to clarify vocabulary.
  • To explain importance if appropriate, repeat the content terms or write down main words.
  • Maintain a normal way of conversation ideal for an adult.
  • Whenever necessary, eliminate disturbances, such as a noisy radio or TV.
  • Including the person with aphasia in debates.
  • Ask for and respect the input of the individual with aphasia, especially with regard to family matters.
  • Encourage contact of some sort, whether voice, gesture, pointing, or drawing.
  • Avoid correcting the speech of a person.
  • Give the entity plenty of time to talk.
  • Help the individual to get active outside of the family. Check for communities in support, such as stroke clubs.
