Acquired (Motor) Speech Disorder
A deficit in the physical production of speech due to damage in the central or peripheral nervous system, affecting motor planning or muscular control
Dysarthria
Apraxia of speech (AOS)
Acquired Language Disorder
Impairments in the comprehension and/or production of language, typically caused by brain damage (e.g. stroke), and include types of aphasia
Language may be affected at levels of word retrieval, sentence structure, and understanding
How can speech and language disorders be distinguished clinically?
Speech disorders (e.g. dysarthria & AOS): intact language structure, difficulty with the motot act of speaking
Language disorders (e.g. aphasia): disrupted language structure or meaning, hut speech mechanisms may be intact
Dysarthria
A type of motor speech disorder characterised by weakness, paralysis, or incoordintion of the muscles used for speech production, resulting in slurred, slow, or disorted speech
muscular control impaired
Dysarthria symptoms
Motor disturbance of respiration, phonation, resonance, articulation, and prosody of neurogenic origin
slow, laboured speech
volume & language is unimpaired
difficulty keeping food/fluid in their mouth.
Common types of dysarthria
Flaccid: weak, breathy voice
Spastic: strained, strangled voice
Ataxic: Slurred, uncoordinated speech
Hypokinetic: monotone, low volume (e.g. Parkinson’s)
Hyperkinetic: involuntary movements affect speech
Unilateral upper motor neuron: mild, imprecise articulation
mixed dysarthria: combination of types (common in progressive diseases)
Apraxia of Speech
A motor planning disorder that affects the voluntary production of speech
disorder of the deliberate execution of purposeful movement, not accounted for by weakness or incoordination of speech muscles
often co-occurs with nonfluent aphasia
difficulty with multisyllabic words & inconsistent errors
easier production of isolated sounds or tense vowels (/pataka/)
motor planning impaired
