Flashcards in Speech Sound Disorders: Types and Theories (Ch. 15) Deck (11):
1

Classification of diseases into groups or subtypes

Nosology

2

Why is it important to have a valid SSD nosology in general?

Accurate diagnosis depends on a valid system of disorder labels.

A valid nosology leads to effective interventions.

3

How can understanding proven SSD subtypes benefit a child with SSD?

Subgroups capture children with similar profiles.

Subtype-specific characteristics may provide clues to associated impairments and suggest therapy targets.

4

Why do we care about knowing the genetic causes of speech sound disorders? (5 reasons)

1. Genetic causes could define SSD subtypes.
2. Clinician can make more precise diagnosis.
3. Knowledge of shared underlying disorder characteristics makes it possible to provide more sophisticated therapy
4. Children with risk genotypes can be identified early for early intervention.
5. Knowing genetic causes can drive research for future pharmaceutical or medical interventions.

5

A disorder characterized by a variety of characteristics co-occurring in the same individual; pattern of multiple anomalies or malformations that regularly occur together, are pathogenically related and have a common cause.

Syndrome

6

The motoric process of speech sounds

Articulation

7

Disordered speech due to paralyzed, weak, or uncoordinated musculature.

Dysarthria

8

A disorder that interferes with the acquisition of written language at the word level, characterized by deficits in accurate and/or fluent word recognition, decoding and spelling in the presence of generally normal oral language skills.

Dyslexia

9

The study of causation of a disease or disorder

Etiology

10

In genetic studies, chromosomal markers can be tested to determine the presence of a disorder

Genetic Association

11

When a disorder is caused by different genetic mechanisms in different families, it is said to be ______________.

Heterogeneous
