Is there a relationship between sleep apnea and aphasia?

Answer 1

No because the causes of the two are unrelated. Sleep apnoea is a problem with your breathing. It happens at intervals very briefly while you lie in bed and is most usually due a physical not a mental over relaxation of the muscles of the soft palate in your throat because the muscles sag and obstruct the passage of air or else very occasionally a consequence of brief interruption of command reception from respiratory brain stem, but only ever while brain is partly resting during your sleep. It is never associated with neural communication while brain is fully awake.

The cause of Aphasia, (which means a complete absence of previously acquired ability to speak a language), is related by a long term neuron loss from the dominant cerebral hemisphere effective during periods both when you are awake and asleep. This is most usually due to brain damage such as after a stroke or head injury which is linked to the brain order that affects your ability to speak and write. Aphasia is sometimes linked to Alexia (word blindness) or Agraphia (writing difficulty), not to any kind of temporary nor permanent breathing disorder
