Do you also have difficulty speaking and understanding? Could it be aphasia?

Can you imagine what it would be like if you suddenly couldn't speak, understand what others were saying, read, or write? It's like being lost in a foreign country and not understanding the language. Sometimes we can't even ask for a glass of water, understand what a friend is saying, or say, "Oh, I'm struggling." That's what aphasia is. It may sound scary, but let's talk about it in detail.

What is Aphasia? Let's understand it simply

Simply put, aphasia is a condition in which the part of your brain that controls language is damaged, affecting your ability to communicate with others, that is, to speak, listen, read, and write. This is not an effect on intelligence . Your intelligence may be intact, but it is the use of language that is impaired.

This condition is most commonly seen after a stroke. It can also be caused by other medical conditions that disrupt brain function. Sometimes, aphasia caused by something temporary, like a migraine, will improve over time. However, aphasia caused by a severe head injury, like a traumatic brain injury, can be long-lasting.

But there's nothing to worry about. There are treatments for this. There are therapies that can help you communicate again and understand different aspects of language.

Are there different types of aphasia?

Yes, there are actually different types of aphasia. To be precise, there are several types known by different names, such as anomic aphasia, Broca's aphasia, and Wernicke's aphasia. The symptoms of each type may vary slightly. But the main thing is that they are related to language. A doctor will tell you exactly which type you have.

How common is this condition?

Talking about how common this is, according to statistics from a country like America, it is said that nearly two hundred thousand people are newly diagnosed with this condition every year. That means that this condition can affect about one in every two hundred and seventy-two people. There are people with this condition in Sri Lanka too, so it is important to be aware of this.

What are the symptoms of aphasia?

Okay, now let's look at the symptoms of aphasia. As I said before, the symptoms can vary slightly depending on the type of aphasia you have. But, most often, you'll see things like this:

Difficulty finding and using words when speaking (Expressive Language)

This is what happens:

• It's hard to find the right words. When you try to say what's on your mind, the words just don't come. Sometimes you want to say "water," but you can't remember the word.
• The wrong words are pronounced. Sometimes a word may be replaced by an unrelated word. Like saying "look" and then "eat".
• The letters in words are reversed and pronounced. For example, "koppe" can be pronounced as "pokkae".
• New words, meaningless words, can be formed.
• Frequently used words or phrases are repeated over and over again.
• You can speak in single words instead of full sentences. For example, instead of saying "I want water," you can say "Water...water...".

Difficulty understanding what others say (Understanding Language)

This is also something that happens to many people:

• When you say the name of something , you may not immediately recognize what it is. For example, if someone says "comb," you have to guess what it is.
• It's difficult to grasp the exact meaning of words.
• It's hard to follow someone's instructions. If someone says, "Go and close the door," it can be hard to understand and do.
• I can't really grasp the details of what's being said during a conversation.
• It's very difficult to understand when more than one person is talking at once.
• It may not be possible to understand jokes and satires like that.

Challenges in Reading and Writing

Questions can also come from this direction:

• It's hard to understand what's written (on the board, on the computer, in books).
• It's difficult to spell words correctly and form sentences.
• Problems can also arise when using numbers. For example, when doing calculations, counting money, or telling time.

Imagine, you have so many things to say in your mind, but something else comes out of your mouth, or the words get tangled. You don't understand what other people are saying. How helpless this feels.

Why does aphasia occur?

So, why does aphasia occur? The main reason is damage to the language centers in your brain. There are several main reasons why this damage can occur:

• Stroke: This is the most common cause. When blood flow to the brain is cut off or there is bleeding inside the brain, brain cells die. This can damage the language centers.
• Traumatic Brain Injury (TBI): A severe blow to the head, such as in an accident, can damage the brain and cause aphasia.
• Brain tumor: When a tumor forms inside the brain, it can press on and damage the language centers.
• Brain infection: Some bacterial and viral infections can travel to the brain and cause damage.
• Brain inflammation: Swelling in the brain can also be caused by inflammatory conditions.
• Progressive neurological conditions: For example, conditions such as dementia and Alzheimer's disease can also cause symptoms of aphasia over time.

In addition, anything that damages the brain or disrupts brain function can cause aphasia. Here are a few more examples:

• Aneurysms - This means that the blood vessels in the brain weaken and bulge like a balloon.
• Brain surgery
• Cerebral hypoxia - This means a lack of oxygen to the brain.
• Concussion - A temporary condition that occurs when the head is hit.
• Congenital conditions - that is, some conditions that are present at birth.
• Epilepsy
• Genetic diseases like Wilson's disease.
• Migraines - Some people may experience temporary symptoms of aphasia along with migraines.
• Radiation therapy or chemotherapy for cancer.
• Toxins and poisons - for example, carbon monoxide poisoning or heavy metal poisoning.
• Transient ischemic attacks (TIAs) - also called 'mini strokes'.

Where exactly in the brain does this affect?

Now you may be wondering, where exactly in the brain is this affected? The type of aphasia you have depends on the specific part of the brain that is damaged. There are two main parts of our brain that are involved in language:

• Broca's area: This is located in the front part of your brain, the frontal lobe. To be precise, on the left side, just in front of the ear. This is what controls the muscles we use when we speak.
• Wernicke's area: This is located in the lateral part of the brain, in the temporal lobe. But on the left side, just above the ear. This is where you understand words and choose the right words to use when speaking.

These two parts work together to make us speak. Imagine, Wernicke's area understands words, chooses which words to say, and sends those signals to Broca's area. Broca's area then sends signals to the muscles to say those words. Simply put, that's what happens.

Who is at higher risk of developing this?

Aphasia can affect anyone of any age. However, it is most common in people over the age of 65, especially after a brain injury such as a stroke. Aphasia can occur suddenly after such events.

Other problems that can occur due to aphasia

Aphasia can cause other problems when you can't communicate your wants and needs to others. Imagine, what if you couldn't say that you were hungry, tired, needed help, or that something was wrong? This can lead to things like:

• Frustration
• Anger ( sometimes violent)
• Loneliness, Isolation
• Depression

This situation affects more than just the patient. Due to the language barrier, caregivers can also feel frustrated and sad about not being able to communicate properly with their loved one. Therefore, it is very important for family members to understand this and be patient.

How is this condition of aphasia diagnosed?

Okay, so how do you diagnose aphasia? A doctor will confirm this after a physical examination and several other tests.

During the exam, the doctor will ask you questions about your health history and symptoms. You may have difficulty answering these questions or understanding what the doctor is asking. Therefore, it is very helpful to have a caregiver or family member with you. They can explain the details for you if necessary.

If your doctor suspects aphasia, he or she will refer you to a Speech-Language Pathologist (SLP). The speech-language pathologist will perform a comprehensive assessment of your ability to understand language (listening), speak and engage in conversation, express yourself, and read and write. This will help determine exactly what type of aphasia you have.

In addition, the doctor will consider the following factors to make a complete diagnosis:

• Fluency: Do you speak smoothly and easily? Is your speech speed, tone, pronunciation, and grammar correct? Can you write without difficulty?
• Understanding: Do you understand what other people are saying? Do the sentences and phrases you say make sense? Can you read and understand written words?
• Repetition: Do you have any difficulty repeating words, phrases, or entire sentences?

What tests are being done for this?

Your doctor may recommend various tests to diagnose aphasia or rule out other conditions with similar symptoms. These tests may also help determine the best treatment.

These tests may include:

• Blood tests
• CT scan (CT - computed tomography scan)
• EEG (Electroencephalogram - EEG) - A test that measures the electrical activity of the brain.
• Electromyogram - A test that measures muscle activity.
• Evoked potentials test - A test that looks at the responses of the nervous system.
• MRI scan (MRI - magnetic resonance imaging scan)
• PET scan (Positron emission tomography - PET scan)

What are the treatments for aphasia?

To manage the symptoms of aphasia, your doctor will first try to treat the underlying cause. For example, if you have had a stroke, restoring blood flow to the affected area of ​​the brain as soon as possible can limit or prevent permanent damage. As you recover, and as your brain heals, your aphasia will likely improve.

Aphasia caused by temporary causes, such as concussions or migraines, may not require treatment and will improve on its own.

However, if your brain has been damaged for a long time or is permanently damaged, speech therapy can help improve your language skills. Speech therapy involves rebuilding or relearning your ability to understand language and teaching you skills to adapt to specific symptoms. Speech therapy can involve your caregivers and family members. This way, they can learn how to best communicate with you and how to help you.

Are you treated with medication?

Depending on the cause of your aphasia, certain medications may be used as treatment. These vary widely. Your doctor will talk to you about the treatment options that are right for you. They will also consider other factors, such as your health conditions and your preferences, when deciding on treatment.

How soon will I feel better after treatment?

How long it takes to recover from aphasia depends on the cause, its severity, and the treatment options available. Your doctor can best tell you about your recovery time. Some people recover quickly, while others may take longer. Patience and effort are key.

What is the outlook for aphasia?

In some cases, aphasia is short-term and gets better over time. However, for others, if there is permanent damage to the language centers of the brain, aphasia can be a lifelong condition. Although speech therapy can reduce the symptoms of aphasia, it may not be able to completely reverse the effects of the condition.

The outlook for aphasia depends on several factors, including your general health and the cause of your symptoms. Your doctor will tell you more about your outlook based on your condition.

Can aphasia be prevented?

Aphasia can come on suddenly and unexpectedly, so it's impossible to prevent it. However, you can try to reduce your risk of developing conditions that can lead to it. Here are some things you can do:

• Eat a balanced diet and exercise regularly: Many conditions that cause aphasia are related to problems with your circulatory system and heart health, so taking care of your overall health is a good first step.
• Don't ignore infections: Eye and ear infections need to be treated quickly. If these infections spread to the brain, they can be serious, even fatal. Some infections can damage the brain and cause aphasia.
• Wear protective equipment: Head injuries can damage the brain. Whether you're working or doing your own work, wearing protective equipment can help prevent injuries that could lead to aphasia. For example, helmets and seat belts in vehicles.
• Managing existing health conditions: If you have long-term conditions like diabetes mellitus and high blood pressure, managing them properly can help prevent complications that can damage the brain and lead to aphasia.

How do I take care of myself with aphasia?

Aphasia can make some everyday tasks a little difficult, but it doesn't have to stop you from living your life completely. Here are some ways you can take care of yourself:

• See your doctor regularly.
• Follow your treatment plan exactly.
• Find support groups. You can learn a lot and find solace in places where there are people like you.
• Find alternative ways to communicate, try new technologies if they are available. Maybe things like pictures, writing, or gestures can help.
• Always carry an identification card with you so that others know that you have aphasia.

Your doctor will give you further recommendations specific to your condition.

When should you see a doctor? When should you go to the emergency room?

If you feel that you are gradually developing symptoms of aphasia, you should see a doctor as soon as possible. Also, if your aphasia symptoms are getting worse over time, talk to your doctor about that as well.

However, if symptoms of aphasia appear suddenly, you should seek emergency medical attention immediately. Symptoms of aphasia that come on suddenly, without warning, can be a sign of a stroke, for example. You should call 1990 (or your local emergency number) immediately.

Also, if you or someone close to you has any of the following symptoms of a stroke (with or without aphasia), seek help immediately:

• Weakness, numbness, or paralysis on one side of the body.
• The story becomes confusing or unclear.
• Drooping of one side of the face or loss of vision in one eye.
• Difficulty swallowing.
• Confusion, restlessness, or agitation.
• Difficulty concentrating, thinking, or remembering.
• A sudden, severe headache that makes it impossible to carry out normal activities.

Other conditions similar to aphasia

There are several other conditions that are similar to, or appear similar to, aphasia. However, these conditions have different underlying causes and symptoms. Some of these conditions include:

• Alexia (word blindness) and agraphia (inability to write): Damage to the parts of your brain that control speech can also affect your ability to read and write. You may see words but not be able to recognize or read them. People with agraphia lose the ability to write. Both can occur together, but this is very rare.
• Auditory verbal agnosia: This is when you hear other people talking and you are unable to recognize what they are saying. This occurs when there is a disruption in the area of ​​the brain that processes sounds or spoken language.

Being diagnosed with aphasia can be a frightening and frustrating experience. You suddenly have to relearn language skills that you used to use so well. Perhaps after a stroke or brain injury, you may find it difficult to attend your monthly book club or give a presentation at work. This can have a big impact on your mental health and your ability to socialize.

Aphasia can sometimes get better on its own, but it can also be a permanent condition. But the important thing is that your doctors can help you adapt, learn new ways to communicate with others, and rebuild relationships.

Finally, remember this (Take-Home Message)

Okay, so let's summarize some of the things you need to remember from what we've talked about.

• Aphasia is not an effect on intelligence, it is an effect on the ability to use language.
• This can be caused by various reasons, such as stroke, brain injuries, tumors, and infections .
• The main symptoms are difficulty speaking, understanding, reading, and writing.
• It is very important to seek medical advice immediately, especially if symptoms come on suddenly, as it could be a sign of a stroke.
• Speech therapy is a very useful treatment method. Also, family support is very valuable.
• Even though this situation is difficult to live with, don't despair. Get help, find new ways to communicate, and try to stay positive. You are not alone.
