Flashcards in Ch. 13: Special Topics in Speech-Language Pathology Deck (57):
1

Psychodynamic Theory

Approach to counseling that views behavior as the product of conflictual interaction between 3 systems: the id, ego, and superego. Anxiety is created when emotions arising from the conflicts among these three system are repressed. Requires resolution of the five psychosexual stages to achieve proper development. Purpose is to make clients conscious of repressed problems and help them to resolve these problems so that the personality can be healthy and whole. (Freud)

2

Client-Centered Theory/Person-Centered Theory

Approach to counseling that states that clients need acceptance and positive unconditional regard in order to develop congruence between their self-concept and their behavior. Foundation of therapy is an empathetic relationship between client and therapist that allows the client to freely experience and express all of his or her emotions in a completely accepting climate. (Rogers)

3

Behavioral Therapy

Approach to counseling that focuses one what is observable, with an emphasis on environmental and external influences. All behavior is caused by current environmental stimuli (including states of motivation), past learning, and the genetic/neurophysiological variables. Behavior is shaped and maintained by immediate response. Reinforcement must be given immediately after a particular behavior has occurred. Positive reinforcement increases the chance that a behavior will reoccur. Negative reinforcement can also cause a behavior to reoccur. Behaviors that occur in the absence of reinforcement will be extinguished. Focuses specifically on areas that affect the client’s communication abilities. Permits the creation of specific goals whose attainment can be objectively measured with data. Allows clinicians to measure the success of the counseling relationship. Allows for documentation of behavioral outcomes.

4

Cognitive-Behavioral Theory

Approach to counseling that suggests that the client’s thoughts are key to his or her feelings and actions. They key variable is the meaning a person attributes to an event. The clinician helps the client focus on the problem, specifically identify the distorted thoughts or cognitions accompanying the problem, and replace them with newer, more rational thoughts that lead to behavior change. Change the client’s thinking → Change the belief system → Change the behavior.

5

Personalization

The inappropriate assumption of responsibility for an event that the client did not cause.

6

Rationalization

In this form of resistance, the client provides a logical but untrue explanation of why something has occurred. E.g., a client who stutters may explain away his lack of a social life by saying, “No one will talk to me because I stutter.”

7

Reaction Formation

Clients who experience this have thoughts or emotions that are shocking and unacceptable to them. Thus, they react with opposite emotions. E.g., the husband of an elderly Alzheimer’s patient secretly wishes his wife would die. In this form of resistance, he sacrifices all his own needs and wants to care for his wife, telling the clinician he loves his wife dearly and could not live without her.

8

Displacement

The client takes his or her feelings of hostility or anger about a situation and transfers them to a safe object or person. E.g., parents becoming angry with you for writing a (correct) diagnosis on a diagnostic report.

9

Projection

Clients attribute their own emotions, thoughts, or actions to someone else. E.g., mother says that school administrators never communicate with one another. School administrators said that the mother never communicated with them.

10

Repression

Clients keep their thoughts and feelings under very strict control, out of view of others. Clients themselves are not aware of these thoughts and feelings, which are below the conscious level.

11

Suppression

Clients keep their feelings and thoughts highly controlled, but they are consciously aware of those feelings. This form of resistance is the norm in some cultures. It should be viewed as a difference, not a defense mechanism, in those situations.

12

Tomography/
Laminography

A computerized radiographic method of take pictures of different planes of body structures. Used to scan brain structures and is frequently used as a neurodiagnostic method for people with communication disorders such as aphasia secondary to stroke.

13

Computerized Axial Tomography (CAT) Scan

X-ray beams circle through segments of the brain and pass through tissue. A camera takes pictures of sections of the structure being scanned. The scanner detects density differences, and a computer analyzes the images generated by the scanning machine and produces pictures of the scanned structures. Can detect hemorrhages, lesions, tumors, and other pathologies. Often used in the diagnosis of neuropathology associated with strokes.

14

Electroencephalography (EEG)

Neurodiagnostic method that records and measures electrical impulses of the brain through small surface electrodes attached to the scalp. Can show different kinds of brain waves associated with different kinds of activity (e.g., talking, listening, thinking). Indicates cerebral pathology by abnormal electrical activity and is often used to detect seizures.

15

Magnetic Resonance Imaging (MRI)

Neurodiagnostic imaging technique where the patient lies completely still in a cylinder container. Used to show fine detail in brain and spinal cord structure. Can also be used to provide images of the soft tissues, large blood vessels, and heart. Based on alignment and realignment of nuclei of atoms in the cell when a structure is placed in a strong magnetic field. Variations introduced in the amount of magnetic radiation will cause alignment and realignment. Such changes produce electromagnetic signals, which a computer analyzes to produce images of the structure. Sometimes detects lesions missed by CT scans. Expensive. Patients may have difficulty tolerating it.

16

Positron Emission Tomography (PET)

Neuodiagnostic procedure that is a type of emission computed tomography that allows imaging of metabolic activity through measurements of radioactivity in the section of the body being viewed (e.g., the brain). The patient is injected with a radioactive substance that spreads throughout the brain. The amount of radioactivity is then scanned and observed differences in the amount of radioactivity suggest different rates of cerebral metabolism. Lower than normal metabolic rate suggests neuropathology. If the patient is suspected of having cerebral dysfunction secondary to a stroke, for example, these scans can be helpful by evaluating the function of blood flow and brain metabolism (whereas MRI and CAT scans only evaluate structure).

17

Single-Photon Emission Computed Tomography (SPECT)

Neurodiagnostic procedure that evaluates the amount of blood flowing through a structure. Also known as regional cerebral blood flow (rCBF). Spreads throughout the cerebral hemispheres and enters the bloodstream. A scanner detects radiation uptake in cerebral blood, and a computer calculates the amount of blood flow in given regions and displays variations in blood flow with different flow colors. Helpful in diagnosing cerebral lesions associated with various Neuropathologies causing communication disorders.

18

Videofluroscopy

A radiologic method of examining movement of internal structures and recording the movement patterns for assessment and diagnosis. It is useful in assessing the functions of the velopharyngeal mechanism, VF, swallowing, and respiratory movement. X-rays are transmitted through the tissue under observation. The soft tissue is coated with barium with the help of a nasal spray and observers can have multiple views of the structures (e.g., frontal, lateral, base, and oblique views of the velopharyngeal mechanism) and their movements. The images are shown on a phosphorescent screen and recorded on a videotape for later examination and diagnosis. Often used to assess swallowing function in patients with confirmed or suspected dysphagia.

19

Craniofacial Anomalies

Abnormalities of the structures of the head and face. Congenital and typically due to genetic factors.

20

Cleft

An opening in a normally closed structure.

21

Palatal Clefts

Various congenital malformations resulting in an opening in the hard palate, the soft palate, or both. Due to disruptions of the embryonic growth processes resulting in a failure to fuse structures that are normally fused.

22

Microforms

Minimal expressions of clefts, including a hairline indentation of the lip or just a notch on the limb.

23

Submucous Cleft/Occult Cleft Palate

Microform where the surface tissues of the soft or hard palate fuse but the underlying muscle or bone tissue do not. There is a midline deficiency or lack of muscular tissue as well as incorrect positioning of the muscles. Children typically present with hypernasal speech and ear infections. Only detectable by X-ray examination and nasopharyngoscopy. Treatment may consist of surgery, placement of a prosthetic device to compensate for the velopharyngeal incompetence, therapy to reduce hypernasality, or a combination of these.

24

Congenital Palatopharyngeal Incompetence (CPI)

Impaired velopharyngeal closing-valve functioning. Not a form of clefting, but is a disorder. Characterized by significant impairment in velopharyngeal functions as revealed by videofluoroscopy or endoscopy, although the structures appear normal. May be caused by a short palate, an occult submucous cleft palate, reduced muscular mass of the soft palate, a deep or enlarged larynx, incorrect insertion of levator muscles, or a combination of these factors. Patients typically have hyper nasal speech (between mild and severe). Can benefit from speech therapy, surgery, prostheses, or a combination of these.

25

V-Y Retroposition/Veau-Wardill-Kilner Method

Method of surgery performed to repair the cleft of the palate. Single-based flaps of palatal mucoperiosteum are raised on either side of the cleft and brought together and pushed back to close the cleft. This push-back (repositioning of the flaps) lengthens the palate and improves chances of velopharyngeal approximation.

26

Von Langenbeck Method

Surgical method performed to repair the cleft of the palate by raising two bipedicled (attached on both ends) flaps of mucoperiosteum, bringing them together and attaching them to close the cleft. This leaves denuded bone on either side and does not lengthen the palate.

27

Pharyngeal Flap

A secondary palatal surgical procedure in which a muscular flap is cut from the posterior pharyngeal wall, raised, and attached to the velum. The openings on either side of the flap allow for nasal breathing, nasal drainage, and production of nasal speech sounds. The flap helps close the velopharyngeal port and thus reduce hypernasality.

28

Pharyngoplasty

Surgical procedure in which substances such as Teflon, silicone, dacron wool/silicone gel bag, and cartilage may be implanted or injected into the posterior pharyngeal wall to make it bulge and thus help close the velopharyngeal port.

29

Syndrome

A constellation of signs and symptoms that are associated with a morbid process. A genetic syndrome is such a constellation with a known genetic basis.

30

Angelman Syndrome

Occurs when chromosome 15 is duplicated from the father or deleted from the mother. Diagnosed between ages 3 – 7, although developmental delay may be apparent 6 – 12 months of age. Children do not show regression. Symptoms include seizures, a stiff and jerky gait, laughter and a happy demeanor, an easily excitable personality, hypermotoric behavior, hand-flapping behaviors, and a short attention span. Though most children have few or no words, nonverbal communication and verbal receptive skills are higher than verbal expressive skills.

Leading inherited cause of intellectual disability in males. Caused by an expanded number of CCG nucleic acid repeating on a specific gene on one of the distal ends of the X chromosome. Physical characteristics include a large, long, and poorly formed pinna, a big jaw, enlarged testes, and a high forehead. Intellectual disability is mild-moderate, becoming more severe in adulthood. Communication problems include jargon, perseveration, echolalia, inappropriate language or talking to oneself, lack of gestures and other nonverbal means of communication that normally accompany speech, voice problems, and articulation disorders. May avoid eye contact, withdraw socially, have limited attention spans, be hyperactive, and have autistic-like social deficiencies. Early intervention is crucial. Typically delayed in all areas of language.

39

Hurler’s Syndrome

A rare, congenital metabolic disease caused by autosomal recessive deficiency of X-L iduronidase. Typically die in teens or even before age 10. Physical characteristics include dwarfism, hunchback, intellectual disability, short and thick bones, a “gargoyle-like” face, SN deafness, and noisy respiration. There is vocal fatigue and hoarseness because of the deposition of metabolites in the larynx.

Thick, everted lips, a large tongue, and small, malformed teeth. Compromised intelligibility.

40

Landau-Kleffner Syndrome

Cause is unknown. Form of aphasia whereby formerly healthy children between ages 3 – 7 years lose their ability to comprehend language and then to speak it. This change can occur suddenly or gradually. Some children are left with severe, permanent language disorders. Others regain many of their language abilities over a span of months or years. For some, relapses and remissions occur. Abnormal brainwave patterns have been detected through EEG. 70% develop epilepsy.

41

Moebuis Syndrome

Causation includes agenesis or aplasia of the motor nuclei of the cranial nerves. There is sporadic, unpredictable occurrence in most cases and autosomal dominant inheritance in some cases.
