Aphasia is a communication disorder that affects a person's ability to speak, understand, read, or write. It often occurs after a brain injury, stroke, or neurological condition, impacting areas of the brain responsible for language. People with aphasia may struggle to find the right words or form sentences, making conversations challenging. There are different types of aphasia, including Broca's aphasia and Wernicke's aphasia, each affecting language skills in unique ways. Treatment typically involves speech therapy, which helps individuals improve their communication abilities and regain confidence in expressing themselves.
