Aphasia

Aphasia is a brain condition that affects your language and speech. It happens when there is damage to the parts of your brain that control how you use and understand language.

There are different ways of experiencing aphasia. This depends on which part of your brain is affected.

Types of aphasia include:

• expressive aphasia (also called Broca's aphasia) — where you have trouble communicating what you want to say
• receptive aphasia (also called Wernicke's aphasia) — where you have trouble understanding what others are saying and have trouble making sense when speaking
• anomic aphasia — where you can understand others but you have trouble using the right words when you communicate
• global aphasia — where you have trouble with understanding, reading, speaking and writing
• primary progressive aphasia (PPA) — where language skills get worse as time goes on

Anomic aphasia is usually mild compared to other types of aphasia. Global aphasia is usually the most severe type of aphasia.

Aphasia can cause difficulty with:

• talking
• understanding language
• reading
• writing and spelling

You might have difficulty with one or more of these skills. Some people have trouble with almost all language skills.

If talking is difficult, you might:

• not be able to remember a word you want to say
• use the wrong word for something
• say words incorrectly
• leave words out of a sentence
• use incorrect grammar
• feel frustrated that you are not being understood

If you have trouble understanding language, you might:

• take longer to understand what someone is telling you
• find it hard to understand long sentences
• have difficulty following instructions
• stop paying attention when someone is talking to you
• not follow what's going on in a movie or on TV
• feel frustrated that you are unable to understand something

If your child is living with aphasia, they might have trouble with:

• schoolwork
• behaving in class
• communicating with friends

Aphasia is caused by damage to the areas of your brain that control language skills. The way you experience aphasia depends on which area is affected and how much damage there is.

The most common cause of aphasia is stroke.

Other causes include:

• head injuries
• brain tumours
• an infection in the brain
• severe epilepsy
• a neurodegenerative disorder such as Alzheimer's disease

Primary progressive aphasia is caused by a type of dementia.

Talk to your doctor about your symptoms if you notice that you are having trouble:

• finding words
• reading
• writing
• understanding others around you

Your doctor can refer you to other professionals who can help.

Your doctor will ask you about your symptoms and refer you to a specialist, such as a neurologist. The specialist might be able to tell that you have aphasia by talking to you. They will probably test your language skills by asking you to:

• name objects
• repeat a sentence
• read and write
• follow simple instructions

To find out what might be causing your aphasia, you might need a scan of your brain. This might mean having a CT or MRI scan.

You might also need to see a speech pathologist or neuropsychologist. They can do more detailed tests to understand your language and thinking skills. This way, they can diagnose what type of aphasia you have and identify exactly which tasks are difficult for you.

Treatment for aphasia involves working on language skills with a speech pathologist.

They will help you learn how to best use the language skills you still have. They can also help you learn new ways to express yourself. The sooner that aphasia treatment begins, the better it works.

You might find it helpful to use a communication aid. This might include a book or iPad with pictures you can point to.

If your child has aphasia, it can help to have support from a special education teacher.

In some people, their language skills may improve without treatment. For others, they may worsen over time.

If you have aphasia, having support to communicate and stay connected socially is vital for your wellbeing. Your friends and loved ones can help.

How should I communicate with someone who has aphasia?

If your friend or loved one is living with aphasia, there are practical ways you can help them communicate.

You can help them understand what you're saying by:

• speaking in short sentences
• making eye contact
• using pictures and hand movements
• repeating important words
• talking about one topic at a time

It's also important to remember that their intelligence has not been affected. You can talk to them in the same tone of voice you would use to speak to anyone else.

You can help them talk to you by:

• being patient and giving them time to express themselves
• offering for them to draw what they mean if they can't think of a word
• checking with them that you've understood them

Living with aphasia can feel very frustrating. It can affect your relationships and quality of life. It may lead to depression or anxiety.

There are things you can do to prevent stroke, which is the most common cause of aphasia. It's important to:

• avoid smoking
• keep your blood pressure and sugar levels under control
• take all your prescribed medicines, especially if you have been told you have a high risk of having a stroke
