What is Aphasia?
Aphasia is an acquired language disorder that occurs following damage to the language-related regions of the brain. In most individuals, the left hemisphere is the dominant side for language. Damage to this area can lead to impairments in speech production, comprehension, naming, repetition, reading, and writing skills.
Aphasia can have a sudden onset and is most commonly seen following a stroke. However, conditions such as traumatic brain injury, tumors, or infections can also cause aphasia.
Causes and Types of Aphasia
Aphasia is generally categorized into two main groups, and the severity depends on the location and extent of the damage:
1. Fluent Aphasias (e.g., Wernicke's Aphasia)
- Speech is fluent, but the content is distorted.
- Use of nonsensical words and "word salad" may be observed.
- Auditory comprehension is significantly impaired.
2. Non-Fluent Aphasias (e.g., Broca's Aphasia)
- Speech production is effortful and fragmented.
- Short, incomplete, and telegraphic sentences are common.
- Comprehension skills are usually better than speech production.
Common Language Issues in Aphasia: Word-finding difficulties (anomia), repetition struggles, loss of reading/writing abilities, and impaired sentence structure. In some cases, motor speech disorders such as dysarthria or apraxia may accompany the condition.
What is Traumatic Brain Injury (TBI)?
Traumatic Brain Injury is damage caused to the brain tissue as a result of a sudden blow to the head or a penetrating injury. It most commonly occurs due to traffic accidents, falls from heights, and sports injuries.
Cognitive and Language Issues Related to TBI
Following a trauma, an individual may experience difficulties in the following areas:
- Cognitive Domain: Decreased attention, memory problems, and difficulty with planning and organization.
- Language and Communication: Word-finding difficulties, disorganized narrative, and inability to understand humor or metaphors.
- Speech Intelligibility: If areas controlling speech muscles are affected, slow and slurred speech (dysarthria) may be observed.
The Role of Speech and Language Therapy
At the Istanbul Atlas University Speech and Language Therapy Unit, the process is structured to support brain plasticity (the brain's ability to reorganize itself):
- Detailed evaluation of language and cognitive-communication skills.
- Evidence-based individual therapy programs for aphasia.
- Strategies for maintaining communication in daily life and family counseling.
- Motor exercises aimed at increasing speech intelligibility.
It should be remembered that the recovery process following brain injury continues over time. Therapy aims to support this process in the most efficient way possible.
