آفازی یکی از شایع‌ترین اختلالات زبانی است که می‌تواند زندگی فرد و خانواده او را به‌طور جدی تحت تأثیر قرار دهد. این اختلال معمولاً در اثر آسیب به بخش‌هایی از مغز که مسئول زبان هستند ایجاد می‌شود و توانایی فرد در صحبت کردن، درک گفتار، خواندن و نوشتن را کاهش می‌دهد. آفازی یک بیماری روانی یا کاهش هوش نیست، بلکه نتیجه مستقیم یک آسیب عصبی است.

آفازی چیست و چرا شناخت آن اهمیت دارد؟

شناخت دقیق آفازی برای تشخیص به‌موقع و شروع درمان مناسب اهمیت زیادی دارد. Many people experience language problems after a stroke or head injury, but they or those around them do not know that these symptoms are a sign of aphasia.

Since aphasia has different degrees and types, public awareness about this disorder plays an important role in reducing patients' anxiety and increasing family cooperation in the treatment process. People with aphasia are usually mentally healthy and only have difficulty expressing or understanding language; Therefore, dealing with them correctly is especially important.

If you or a loved one is facing aphasia, this guide can provide a clearer path to understand the condition and choose the best treatment method.

How is aphasia created? Examining the causes and risk factors

Aphasia occurs when language parts of the brain are damaged, especially in the left hemisphere. The most common cause of aphasia is stroke, which disrupts blood flow to vital areas of the brain. In this situation, nerve cells are damaged and the ability to process language decreases.

Severe blows to the head, such as car accidents or falling from a height, are another important cause of aphasia. These types of injuries may occur suddenly and at any age. Also, brain tumors that grow gradually can cause progressive aphasia.

Other causes of aphasia include brain infections, brain hemorrhage, neurodegenerative diseases such as Alzheimer's, and some seizures. In some cases, aphasia occurs temporarily after severe migraine attacks or seizures. Risk factors for aphasia include aging, high blood pressure, diabetes, heart disease, and a sedentary lifestyle. People who have these factors are more exposed to stroke and as a result aphasia.

Knowing the exact cause of aphasia is very important to choose the right treatment method. The treatment of stroke-induced aphasia is fundamentally different from the treatment of progressive aphasia. For this reason, careful medical evaluation and brain imaging play a key role in the management of this disorder.

Types of aphasia and their differences with each other

Aphasia is not a uniform disorder and it is divided into different types depending on the location and severity of brain damage. Knowing the types of aphasia helps therapists to design a more accurate treatment plan.

Broca's aphasia

Wernicke's aphasia

Wernicke's aphasia is another type of this disease in which a person can speak fluently, but his speech is often slurred and language comprehension is severely impaired. These people usually do not notice their language mistakes.

Global aphasia

Global aphasia is considered the most severe type of this disease. In this case, both language comprehension and expression are severely impaired, and the person loses the ability to communicate effectively. This type is usually caused by massive strokes.

Anomic aphasia

Another type is anomic aphasia, which is characterized by difficulty naming objects. A person may know the concept but not be able to remember the right word. This type is milder and the response to treatment is better.

Diagnosing the type of this disease is the first step towards effective treatment and allows the speech therapist to design more targeted exercises.

Dysarthritis = difficulty in speech
Aphasia = difficulty in language and meaning

While in aphasia:

• The main problem in word selection, sentence formation and language comprehension is
• Errors are more linguistic than movement

📌 key difference:
Apraxia of speech = disorder in speech planning
Aphasia = disorder in language system

Aphasia difference and developmental language disorders

Language developmental disorder is usually seen in children and is present from the beginning. In this case:

• The child has difficulty learning the language from the beginning
• There is no obvious brain damage

But aphasia:

• It usually occurs after a brain injury such as a stroke or trauma
• Language already existed and then it was disrupted

Difference between aphasia and cognitive problems or dementia

In diseases such as Alzheimer:

• Memory, attention and thinking are gradually damaged
• Speech problem is part of a wider disorder

But in aphasia:

• Intelligence and thinking are usually healthy
• The main problem is limited to language and communication

Disturbance	main problem
Aphasia	Language processing and comprehension
dysarthritis	Weakness or incoherence of speech muscles
Apraxia of speech	Planning speech movements
Language developmental disorder	Language learning problem from childhood
dementia	General loss of cognition and memory
