Study Guide Flashcards
What is Flaccid Dysarthria also known as?
Bulbar Palsy
Describe Flaccid Dysarthria
- muscle weakness/reduced tone
- negative impact to speed, range, and accuracy of movement
- hypernasal
- nasal emission
- audible inhalation
- speaks in short phrases
- hypotonia
- asymmetry
- fasciculations
Describe Spastic Dysarthria
- slow movement, reduced range, face
- all areas of speech are affected
- spasticity and weakness
- initially flaccid, then spastic
- pathological reflexes
- pseudobulbar affect—Emotional lability
Describe Ataxic Dysarthria
- irregular articulatory breakdowns (inconsistent)
- Irregular AMR’s
- Excess and Equal stress
- distorted vowels
- “drunken speech”
- poorly coordinate movement pattern
- scanning or staccato pattern of speech
- ataxic gait
- freidrich’s ataxia
Describe Hypokinetic Dysarthria
- decreased range of motion (ROM)
- associated with basal ganglia pathology (PARKINSONS)
- affects aspects of motor control (preparation, maintenance, switching of motor programs)
- increased rate of speech with reduced intelligibility
- monopitch and monoloudness
- palilalia
Describe Hyperkinetic Dysarthria
- Basal ganglia control circuit or indirect activation pathways
- primarily affects prosody
- abnormal, rhythmic, or irregular, unpredictable, rapid or slow involuntary movements
- chewing/swallowing issue common
- voice feels shaky, tight, closed off
- excessive involuntary movements that may interfere with speech production
Describe Mixed Dysarthrias
- speech characteristics are a combo of those found in single dysarthrias
- prominence of dysarthria type that is most evident can change over time
- caused from neurological damage to two ro more parts of the motor system (combined events, 2+diseases)
- ex: brainstem stroke, ALS (bilateral damage to both direct and indirect pathways)
- TBI-Cerbral and cranial nerve damage (ataxic flaccid dysarthria)
What are some concomitant disorders that may influence/impact therapy?
- depression
- schizophrenia
- conversion disorder
- Somatization Disorder
Volitional disorders (factitious disorders & malingering)
Describe depression
- more common in confluent aphasia than global or fluent aphasia (awareness)
- common in parkinson’s, epilepsy, Alzheimers, MS, and Huntington’s
- TBI,stroke, more often with lesions of L than R
Describe Schizophrenia
- delusions, hallucinations, disorganized or catatonic behaviors, affective flattening, disorganized speech.
- social isolation/withdrawal
- peculiar behavior (talking to oneself)
- conditions leading to schizophrenic behavior: closed head injury (CHI), Wilson’s Disease, Demyelinating Disease
Describe conversion disorder
- Physical symptoms without demonstrable organic causes but that suggest a medical or neurologic cause and for which there is at least circumstantial evidence of a link between symptoms and psychological factors or conflicts.
- in other words: it is a condition in which you show psychological stress in physical ways, it’s a health problem that starts as a mental or emotional crisis–a scary or stressful incident of some kind–and converts to a physical problem.
- actual loss of volitional muscle control or sensation that is not consciously motivated
Describe Somatization disorder
- chronic illness characterized by recurrent, multiple physical complaints, and a belief that one is ill
- numerous dramatic complaint involving multiple organs
- insists on and receive multiple tests/treatment, and fail to be reassured when told there is no evidence of an organic disease
Describe factitious disorders
- feign physical or psychological symptoms but do so for uncontrolled/unconscious psychological reasons that lead them to seek out the role of a sick person
- loners with personality disorders often with a history of abuse, trauma, and deprivation
- Munchausen’s Syndrome–pathological lying
Describe Malingering
- deliberate, vountary feigning of physical or psychological symptoms for consciously motivated purposes (e.g., avoid work, for financial gain, to evade prosecution)
- may stage events (e.g., getting hit by a car) alter medical tests, take advantage of natural event, etc..
- not a mental disorder
What is Apraxia of Speech?
-apraxia results from an impaired ability to generate the motor programs for speech movements, rather than from the disordered transmission of controlling messages to the speech musculature. Apraxia is a planning/programming problem, not a movement problem like dysarthria
What is dysarthria?
the muscles of the mouth, face and respiratory system may become weak, move slowly, or not move at all after a stroke or other brain injury.
Describe signs/symptoms of Apraxia
- errors are inconsistent and unpredictable
- different errors occur in spontaneous speech versus repetition
- patient’s spontaneous speech contains fewer errors than does his/her speech in repetition tasks
- there are islands of clear speech; when producing over-learned material or material that has become automatic, the patient will speak clearly
- substitutions are the most common type of error, with others normally being approximations of the targeted phoneme
- anticipation of errors causes dysfluent speech
- groping, trial and error types of articulatory movements
Describe s/s of dysarthria
- errors are consistent and predictable
- errors are mainly distortions and omissions
- slurred speech
- speaking softly or barely able to whisper
- slow rate of speech
- hoarseness
- breathiness
- changes in vocal quality
See table of etiologies/types of dysarthrias & systems of speech affected
in study guide
Cranial Nerve I
- olfactory
- sensory
- function: smell
- symptom: lack of smell
Cranial Nerve II
- Optic
- sensory
- function: vision: controls central and peripheral vision, superior and inferior fields
- Symptom: vision problems. Patient may not be able to read printed material
Cranial Nerve III
- Oculomotor
- both (sensory and motor)
- function: eye movement: pupil constriction
- Symptom: ptosis
Cranial Nerve IV
- Trochlear
- both (S&M)
- Eye movement: acts as pulley to move eyes down toward tip of nose
Cranial Nerve V
Trigeminal
both (S&M)
Function: Jaw movement; face, mouth, jaw (and scalp) sensation. Innervates forehead, cheek and jaw.
Symptom: Lack of sensation when stroked. Weak motor strength of jaw (temporal and Masseter muscles)
