Identify the dysarthria type Flashcards
Lesion to one or more CNs or spinal nerves
Flaccid dysarthria
Lesions to the cerebellum and its connections
Ataxic dysarthria
Lesions to LMNs that innervate respiratory musculature or CNs that innervate speech musculature
Flaccid dysarthria
Combined weakness & spasticity (UMN)
Spastic dysarthria
Muscle weakness
Flaccid dysarthria
Irregular articulatory breakdowns
Ataxic dysarthria
Etiology: any process that damages the direct and indirect activation pathways bilaterally.
Spastic dysarthria
Problems at the level of the FCP (LMN involvement)
Flaccid dysarthria
Degenerative diseases, tumor, & trauma (more than one type of dysarthria can be caused by these things)
- Flaccid
- Spastic
- Ataxic
Damage to UMNs (unilateral)
Unilateral upper motor neuron (UUMN) dysarthria
Damage to internal capsule, lobar, cortical, brainstem, and/or thalamus
Unilateral upper motor neuron (UUMN) dysarthria
Can be caused by demyelinating diseases (more than one type of dysarthria can be caused by these things)
- flaccid
- ataxic
- UUMN
Irregular speech AMRs
Ataxic dysarthria
Excess & equal stress patterns (two kinds)
Ataxic & spastic dysarthria
Harsh, strained-strangled quality with an effortful grunt at the end of vocalizations
Spastic dysarthria
Reduced muscle tone
Flaccid dysarthria
Apparent in articulation (imprecise irregular breakdowns), phonation (harshness, reduced loudness), & prosody (slow rate & slow/imprecise/irregular DDKs)
Unilateral upper motor neuron (UUMN) dysarthria
excess loudness variations & poor pitch control
Ataxic dysarthria
low pitch; pitch breaks; reduced stress; monoloudness
Spastic dysarthria
