Flashcards in Definitions Deck (8):
1

ALS

•Unknown etiology, affects motor neurons in brain and spinal cord

dysarthria will affect speech

2

Bulbar ALS

•affects speech more than extremities

•needs phone communication

3

Spinal ALS

•affects extremities first

•needs writing systems

4

Guillain Barre Syndrome

•Progressive destruction and regeneration of myelin sheath

•Paralysis starts in lower extremities and moves upwards and occurs with 1-3 weeks of onset

•Nerve function and muscle strength gradually return

•Dysarthria is primary issue

•85% fully recover, of the 15% remaining only a few require long term speech intervention

•AAC systems typically consist of low tech options and are usually only needs for weeks or months

5

Multiple Sclerosis

•Disease of the CNS, myelin sheath, unknown cause

dysarthria

6

Parkinson's Disease

•Loss of dopamine producing neurons in the basal ganglia

•Adult onset

•Dysarthria is common approximately 70%

7

Brain Stem Stroke

•Damage to the central nervous system structures located in the brainstem

Stroke that disrupts circulation of lower brainstem

•Results in dysarthria or anarthria (loss of speech)

8

Locked-in syndrome

•Closely related to brain stem stroke

•Cause-typically a basilar artery stroke

•Results in total loss of motor control except for eye blinks and vertical eye movement
