Aphasia is a language disorder that affects an individual's ability to communicate. It is caused by damage to the language centres of the brain and often occurs following a stroke or head injury. A third of stroke patients experience aphasia, which can manifest as expressive aphasia (difficulty speaking) or receptive aphasia (difficulty understanding speech). Aphasia does not affect intelligence, but it can cause frustration and isolation due to the challenges it poses to effective communication. The severity of aphasia depends on factors such as the cause and extent of brain damage, with treatment options varying accordingly.
What You'll Learn
Strokes in the left side of the brain can cause aphasia
Strokes are the biggest cause of aphasia, a complex language and communication disorder. A third of people who have a stroke will experience aphasia. A stroke occurs when a blood clot or a leaking or burst vessel cuts off blood flow to part of the brain. Brain cells die when they do not receive their normal supply of blood, which carries oxygen and important nutrients.
People with aphasia may struggle with communicating in daily activities at home, socially, or at work. They may also feel isolated. Aphasia does not affect intelligence, and stroke survivors remain mentally alert, even though their speech may be jumbled, fragmented, or hard to understand. Treatment options are available to help people with aphasia adapt if the symptoms are permanent. Speech therapy can help people with aphasia improve their language abilities.

Aphasia affects speech, reading, writing and listening
Aphasia is a language disorder that affects your ability to communicate. It impacts your ability to speak, read, write and listen. Aphasia usually occurs after a stroke or a head injury, but it can also develop slowly due to a brain tumour or progressive neurological disease. It affects different aspects of language, depending on which part of the brain has been damaged by the stroke.
Aphasia can cause difficulties with expressive language. This includes finding the right words, saying the wrong word, switching letter sounds, making new words, repeating common words or phrases, or saying single words instead of full sentences. For example, a person with Broca's aphasia may say "walk dog", meaning "I will take the dog for a walk", or "book book two table" for "there are two books on the table".
It can also cause difficulty in understanding language. This includes not easily recognising an object's name or a word's meaning, following directions, grasping the details of a conversation, listening to more than one person speaking at a time, or not understanding jokes or puns. People with Wernicke's aphasia may string together words that sound like a sentence but don't make sense, such as "you know that smoodle pinkered and that I want to get him round and take care of him like you want before".
Aphasia can also affect reading and writing. This includes not understanding written language, spelling words and forming sentences, and using numbers. For instance, people with Wernicke's aphasia may be unable to recognise or read written words, even though they can see them.
While aphasia affects a person's ability to communicate, it does not impact their intelligence. Stroke survivors remain mentally alert, even though their speech may be jumbled, fragmented or hard to understand.

Aphasia is a language disorder, not an intelligence disorder
Aphasia is a complex language and communication disorder that affects a person's ability to communicate. It is caused by damage to the language centres of the brain, usually after a stroke or traumatic brain injury. It is important to note that aphasia is a language disorder, not an intelligence disorder. While it impairs an individual's ability to communicate, it does not affect their intelligence.
A stroke occurs when a blood clot or a leaking or burst vessel cuts off the blood supply to a part of the brain. This interruption of blood flow causes brain cells to die or become damaged, particularly in areas that control language. As a result, individuals with aphasia may experience difficulties in speaking, understanding speech, reading, and writing.
The effects of aphasia can vary, with some individuals experiencing problems with expressive language, such as finding the right words or saying the wrong word. Others may struggle with understanding language, following conversations, or recognising the names of objects. Reading and writing can also be challenging, as individuals may have difficulty understanding written language or forming sentences.
It is important to understand that while aphasia affects language abilities, it does not impact a person's intelligence. Individuals with aphasia still possess their knowledge and thoughts but may struggle to communicate them effectively. This distinction is crucial in recognising that aphasia is a language disorder and not an intelligence disorder.
Treatment options are available to help individuals with aphasia improve their communication skills. Speech therapy, for example, can help individuals rebuild their language abilities and adapt to specific symptoms. Additionally, support groups and alternative communication methods, such as gestures or electronic devices, can assist individuals in reconnecting with others and improving their quality of life.

Aphasia can be either fluent or non-fluent
Aphasia is a language disorder that affects an individual's ability to communicate. It can impact speech, comprehension of language, reading, and writing. Aphasia is most often caused by strokes in the left side of the brain, which controls speech and language. While stroke is the most common cause of aphasia, it can also be caused by other brain injuries, infections, or tumours.
There are two main types of aphasia: fluent and non-fluent. The key distinction between the two lies in how a person speaks and understands language. Fluent aphasia affects the meaning of language, while non-fluent aphasia affects the production of language.
Fluent Aphasia
Fluent aphasia is characterised by fluent speech that is grammatically correct but lacks meaning. People with fluent aphasia may speak in long, rambling sentences that are difficult to understand. They may also have impaired auditory comprehension and struggle with repeating words or phrases. A common feature of fluent aphasia is the use of jargon or neologisms (made-up or invented words). People with fluent aphasia often have difficulty understanding spoken or written language, and may not recognise their own errors in communication.
The most common type of fluent aphasia is Wernicke's aphasia, caused by damage to the Wernicke's area of the brain, which is responsible for language comprehension. Other types of fluent aphasia include conduction aphasia, anomic aphasia, and transcortical sensory aphasia.
Non-Fluent Aphasia
Non-fluent aphasia, also known as Broca's aphasia or expressive aphasia, is characterised by slow and effortful speech. Individuals with non-fluent aphasia have difficulty producing words and sentences. Their speech may consist mostly of nouns and verbs, with incorrect or missing grammar. While they often understand written and spoken language, they may struggle with complex sentences. People with non-fluent aphasia are typically aware of their communication challenges, which can lead to emotional frustration.
The most common type of non-fluent aphasia is Broca's aphasia, caused by damage to the Broca's area of the brain, which is responsible for speech production. Other types of non-fluent aphasia include global aphasia, transcortical motor aphasia, and mixed non-fluent aphasia.

Aphasia can be treated with speech and language therapy
Aphasia is a complex language and communication disorder resulting from damage to the language centres of the brain. Strokes are the biggest cause of aphasia, with around a third of people who have a stroke experiencing aphasia. Aphasia affects a person's ability to communicate and understand language, but it does not affect their intelligence.
Speech and language therapy (SLT) is an effective treatment for aphasia, improving functional communication, reading, writing, and expressive language. SLT can help rebuild a person's understanding of language and teach them skills to adapt to specific symptoms. Therapy is most effective when it begins soon after a brain injury.
SLT can take place in a group setting, where people with aphasia can practice their communication skills in a safe environment. Group therapy allows participants to practice starting conversations, taking turns, and fixing broken conversations. Computer-assisted therapy can also be beneficial, especially for relearning verbs and word sounds.
SLT can also involve caregivers and loved ones, teaching them how to best communicate with and help the person with aphasia.

Frequently asked questions
Aphasia is a language disorder that affects your ability to communicate. It can impact your speech, as well as the way you write and understand both spoken and written language.
A stroke occurs when a blood clot or a leaking or burst vessel cuts off blood flow to part of the brain. Brain cells die when they do not receive their normal supply of blood, which carries oxygen and important nutrients. If the stroke occurs in the left side of the brain, which controls speech and language, it can result in aphasia.
People with aphasia may speak in short or incomplete sentences, have trouble finding words, not understand other people's conversations, not understand what they read, and write sentences that don't make sense.
The main treatment for aphasia involves treating the underlying cause, as well as speech and language therapy. The person with aphasia relearns and practices language skills and learns to use other ways to communicate. Family members often participate in the process, helping the person communicate.
