174
Vascular disturbances in the left or right carotid/ left, right, or middle cerebral arteries can produce
Dyarthrias
175
Left middle cerebral artery disturbances can cause
Apraxia and Aphasia
176
Know the localization of neurologic dieases:
1) focal- single area (e.g. left frontal lobe) 2) multifocal- involving more than one area or more than one group of structures (e.g. cerebellar and cerebral hemisphere plaques associated with MS) 3) Diffuse- Roughly symmetric portions (e.g. cerebral atrophy associated with dementia)
177
What are the development of symptoms?
acute- within minutes subacute- within days chronic-within months
178
Evolution or course of a disease
Transient- symptoms completely resolve after onset Improving- Severity is reduced, but symptoms are not involved Progressive- Symptoms continue to progress or new symptoms appear Exacerbating-remitting- Symptoms develop, improve, reoccur, and worsen Stationary (Chronic)- Symptoms remain unchanged To Improve Properly Eat Seaweed
179
Inflammatory Diseases
Infectious Processes- (e.g. meningitis, encephalitis)
180
Toxic Metabolic Diseases
Vitamin deficiencies, thyroid Hormone deficiency, hypoxia, hypoglycemia, and drug toxicity
181
Neoplastic Disease
Cancer
182
Trauma
Gunshot wound, fall, auto injury, blast
183
What is the most common cause of neurologic deficits?
Vascular Disease
184
Most common cerebrovascular disease is
Stroke aka Infarct aka Cerebrovascular Accident (CVA)
185
Neurons deprived of oxygen and interruption of blood supply
ischemia
186
What are the two types of onset for MSDs?
Congenital/developmental and Acquired
187
A MSD can take one of 5 courses: congenital, _____, _____, improving, and _____-_____.
chronic, progressive/degenerative, and exacerbating-remitting
188
Determining the site of a lesion can _____.
Predict certain speech deficits
189
7 locations for MSD lesions are:
- neuromuscular junction - peripheral & cranial nerves - brainstem - cerebellum - basal ganglia - pyramidal or extrapyramidal pathways - cerebral cortex
190
There are 6 different categories for neurological diagnosis: degenerative, inflammatory, traumatic, _____-_____, _____, and _____.
Toxic-metabolic, neoplastic, and vascular causes
191
T/F: By itself, MSD is usually diagnostic of a particular neurologic cause or disease?
False
192
What determines the distinctive pattern of speech deficits associated with MSD?
Pathophysiology
193
Pathophysiology variable: | Speech components involved ...
categorized by speech subsystems affected (i.e. breathing, phonation, articulation, or resonance)
194
T/F: Pathophysiology variable: | Severity does Not differentiate among MSDs.
True
195
Pathophysiology variable: Severity ...
relevant for treatment/management decisions
196
Pathophysiology variable: | Perceptual characteristics ....
crucial to differential diagnosis and management
