Neurogenic Communication Disorders
Neurogenic communication disorders are caused by damage to the central or peripheral nervous system and result in difficulty with communication. These challenges may occur suddenly after an acute event, such as a stroke or traumatic brain injury, or may be gradual as a part of a progressive disorder (e.g. Parkinson's Disease, dementia, or primary progressive aphasia). Neurogenic communication disorders include:
Aphasia is a language disorder that involves varying degrees of impairment in spoken language expression, spoken language comprehension, written expression, and reading comprehension.
Apraxia of Speech
Apraxia of speech is a motor speech disorder that affects communication between the brain and the muscles used for speech. Symptoms may include difficulty initiating or imitating speech, substitution of of sounds/words, and slow speech.
Dysarthria is a motor speech disorder that affects the strength and coordination of the muscles used for speech. Symptoms may include slurred speech or mumbling, speaking too quickly or slowly than intended, speaking quiet or louder than intended, and sounding hoarse, breathy, or monotone.
Cognitive communication disorders are characterized by impaired functioning of one or more cognitive processes, including attention, memory, organization, problem solving, reasoning, executive functioning, insight, and judgement.
