Aphasias are language disorders that can arise as a result of brain injuries, such as strokes, tumors, head trauma or neurodegenerative diseases. These alterations affect a person's ability to communicate effectively, both in understanding and expressing language. The severity and type of aphasia depend on the location and extent of the brain injury. Next, the main types of aphasias and their distinctive characteristics will be explored.
Broca's aphasia

This difficulty is due to a disruption in the connection between the areas of the brain responsible for language comprehension and production.
Main characteristics:
- Difficulties in repeating words or phrases.
- Comprehension and expression of language relatively preserved.
- Disrupted connection between areas of the brain.
Transcortical aphasia
Transcortical aphasia is a type of aphasia in which the ability to communicate is mainly affected, but the Language comprehension may be relatively intact. There are different types of transcortical aphasia, such as motor transcortical aphasia and sensory transcortical aphasia, each with its own distinctive characteristics. In general, people with transcortical aphasia may have difficulty starting or maintaining a conversation, but can understand language when it is presented appropriately.
Main characteristics:
- Difficulties in communication, but preserved understanding.
- Different types, such as motor and sensory transcortical aphasia.
