Problems with a patient’s voice, speech, language, hearing, or cognition can hinder their ability to communicate. Failure to diagnose and treat communication difficulties can lead to despair, isolation, and a decline in independence. An issue with the neuromuscular control of speech can lead to a variety of motor speech problems, one of which is dysarthria. When the muscles used to make speech are very weak or uncoordinated, a condition known as apraxia develops. When parts of the brain that are in charge of understanding and expressing language are damaged, a language disease called aphasia develops. On the other hand, a cognitive-communicative disorder hinders communication by affecting the pragmatics, or social rules, of language. Interacting with one’s surroundings is made possible by the multi-faceted and ever-changing communication process. People can share their feelings, wants, and ideas via communication. Brain activity, auditory processing, speech generation, and muscular coordination are all involved in the complex communication process.
