Speech Sound Disorders: Types and Theories (Ch. 15) Flashcards
Classification of diseases into groups or subtypes
Nosology
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.
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.
Why do we care about knowing the genetic causes of speech sound disorders? (5 reasons)
- Genetic causes could define SSD subtypes.
- Clinician can make more precise diagnosis.
- Knowledge of shared underlying disorder characteristics makes it possible to provide more sophisticated therapy
- Children with risk genotypes can be identified early for early intervention.
- Knowing genetic causes can drive research for future pharmaceutical or medical interventions.
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
The motoric process of speech sounds
Articulation
Disordered speech due to paralyzed, weak, or uncoordinated musculature.
Dysarthria
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
The study of causation of a disease or disorder
Etiology
In genetic studies, chromosomal markers can be tested to determine the presence of a disorder
Genetic Association
When a disorder is caused by different genetic mechanisms in different families, it is said to be ______________.
Heterogeneous
