T4: Lecture 7 Flashcards

1
Q

Why is it difficult to define a childhood disorder?

A
  1. Children are more likely to act out than seek help
  2. Certain degree of deviance and irrotational behaviour is typical in normal development
  3. Some disorders cause little/no conscious distress

Q

What is the diagnostic criteria for Intellectual Disability?

A
  • Onset BEFORE AGE 18
  • Deficits in intellectual functioning determined by intelligence testing (around 2 standard deviations below mean) and as appropriate for social/cultural context
  • Deficits in adaptive functioning
  • > communication, social, practical

Q

What is the etiology of ADHD?

A

Genetic influences
-50-75% heritability

Structural abnormalities

  • Under-responsive prefrontal and striate regions
  • > dorsolateral region (attention/exectuive functioning)

Neurotransmitter abnormalities
-Dopamine levels often LOW

17
Q

What are the treatments for ADHD?

A

BIOLOGICAL

Stimulant medications e.g. Ritalin

  • Has high abuse potential
  • Stimulates active prefrontal cortex

Non-stimulant medications e.g. trattera

  • Lower abuse potential
  • Less effective

PSYCHOLOGICAL: behaviour therapy

18
Q

What is Oppositional Defiant Disorder?

A

Genetic Factors

Familial Risk Factors

  • Child Abuse
  • Family conflict

Sociocultural risk factors

  • Poverty
  • Past antisocial behaviours
  • Dangerous neighbourhoods where anti-social behaviour is displayed
24
Q

What is the BEST predictor for ODD and CD?

A

25
Q

What are treatments for ODD and CD?
