Understanding Aphasia - Symptoms, Types, Causes, and Treatment Options

Introduction

In neurology, Aphasia is a disease in which you have difficulty speaking or understanding what others are saying. It is usually caused by injury to a section of your brain, but it can also occur as a result of illnesses that interfere with how your brain functions. There are several varieties of aphasia. The sort of aphasia you have is determined by where the damage occurred in your brain. 

This illness is nearly always an indication of a larger issue, such as a stroke or traumatic brain injury. It may also occur as a brief side effect of illnesses such as migraines. 

Aphasia is often treated, especially if the underlying illness is reversible or self-healing. Aphasia is a condition that shares or overlaps with several other speech-related disorders and problems, including dysarthria, dysphasia, and apraxia.

Types of Aphasia

The primary types of aphasia are:

• Broca's aphasia

• Wernicke's aphasia

• Global aphasia

• Anomic aphasia

• Transcortical aphasia

• Conduction aphasia

• Primary progressive aphasia (PPA)

Symptoms

There are various types of aphasia and aphasia-related conditions. While the symptoms of aphasia are very similar, there are some significant variances. To understand how aphasia works, it's helpful to know a little bit about two distinct regions of the brain that collaborate when you talk:

• Broca’s area: This area of the brain is named after the French physician who found it regulates the muscles that allow you to talk. It is a part of your frontal lobe, located on the left side just forward of your temple.

• Wernicke’s area: This area of the brain is named after a German neurologist who discovered that it affects your capacity to understand and choose the appropriate words to use when speaking. It is a portion of your temporal lobe and is normally located on the left side, just above your ear.

Causes

Aphasia can result from any disorder that harms the brain. It can also occur when difficulties interfere with your brain's processes. Alzheimer's disease, aneurysms, brain surgery, brain tumors, cerebral hypoxia, concussion and traumatic brain injury, dementia and frontotemporal dementia, developmental disorders and congenital problems, epilepsy or seizures, genetic disorders, brain inflammation caused by viral or bacterial infections, migraines, radiation therapy or chemotherapy, toxins and poisons, strokes, or transient ischaemic attacks are all possible causes.

Diagnosis and Tests

Aphasia is diagnosed by a physical exam, inquiries about your history, diagnostic imaging and testing, and other measures. In some circumstances, a healthcare physician will advise doing many tests to rule out other disorders or causes that could cause symptoms similar to those seen with aphasia. This includes sensory and nerve function testing, cognitive and memory tests, as well as diagnostic and imaging examinations.

When providers suspect aphasia, they can do a variety of testing. In most circumstances, a speech-language expert can assist in determining the type of aphasia, if any, a person has. The tests may also aid in detecting what caused the aphasia, as well as determining whether the reason is curable and what kind of treatments will be most effective.

Blood tests, computerized tomography (CT) scans, electroencephalograms (EEG), electromyograms, evoked potentials tests, genetic testing, magnetic resonance imaging (MRI), positron emission tomography (pet) scans, spinal taps (lumbar punctures), and x-rays are all options.

Management and Treatment

Unfortunately, there is no direct remedy for aphasia. However, it is typically curable in some fashion. Typically, the first step in treating aphasia is to address the underlying problem. In cases like stroke, promptly restoring blood flow to the afflicted part of the brain can sometimes limit or avoid irreversible damage. 

When aphasia occurs as a result of a transient condition, such as a concussion, migraine, seizure, or illness, it is usually temporary. The aphasia normally improves or resolves completely as you recover and your brain heals with time and treatment.

Speech therapy can sometimes help persons with long-term or chronic brain injury, such as severe strokes, to improve their language ability. These therapeutic alternatives can also assist a person in better comprehending people and compensating for their aphasia. Speech therapy can also involve carers and loved ones, so they understand how to best communicate with and assist you.

Treatments

Aphasia-causing disorders can be treated with a variety of drugs. As a result, your healthcare professional is the finest source of information on potential treatments that will benefit you. They can personalize treatment solutions to your specific requirements and circumstances. They will also take into account any underlying health conditions or preferences that may affect your treatment.

Side effects

The potential side effects or complications are determined by the underlying cause of the ailment and the specific treatments performed. Your healthcare professional can describe the most likely side effects or consequences for your unique instance. You can also ask them for further information on how you can lessen or possibly avoid negative effects.

Prevention

Aphasia occurs unpredictably, making it impossible to prevent. You can, however, try to avoid or lessen your risk of getting the underlying illnesses. You can accomplish some of the following things:

• Maintain a healthy weight by following a well-balanced diet. 

• Infections should be treated.

• Wear protective clothing. 

• Manage your medical conditions.
