What is Aphasia?
Aphasia is a language disorder that occurs due to damage to the brain’s language centers, affecting a person’s ability to communicate effectively. This condition can impact speaking, understanding, reading, and writing skills.
Types of Aphasia
- Broca’s Aphasia: Difficulty speaking fluently, but comprehension is intact.
- Wernicke’s Aphasia: Fluent speech, but it lacks meaning and comprehension is impaired.
- Global Aphasia: Severe impairment in all language skills.
Causes of Aphasia
Aphasia can result from a stroke, traumatic brain injury, brain tumor, or degenerative disease. The severity and type of aphasia depend on the location and extent of damage to the brain.
