What term describes the loss of language function and inability to speak?

• A. Dyslexia
• B. Aphasia
• C. Apraxia
• D. Alexia

Answer: (B)

The term that describes the loss of language function and an inability to speak is aphasia. Aphasia is often the result of damage to the areas of the brain responsible for language, such as Broca's area or Wernicke's area, typically due to a stroke or head injury. It affects communication abilities, including speaking, understanding language, reading, and writing.

Dyslexia, on the other hand, refers to difficulties in reading despite normal intelligence and is primarily related to language processing. Apraxia involves difficulty with motor planning and coordination necessary for speech, which does not directly affect language comprehension or the ability to use language itself. Alexia is specifically a form of dyslexia that affects reading skills, indicating a reading impairment rather than an overall inability to communicate. Each of these conditions has distinct characteristics, but aphasia is uniquely characterized by a loss of language capability.
