Why is adolescence such a tricky time?

A

A lot of physical and sexual changes, social and academic pressures, personal doubts etc that produce anxiety, confusion and depression

Q

What are the different types of childhood disorders?

A

Many, including anxiety and depressive disorders, that have adult counterparts
Others disappear/radically change into adulthood e.g. bedwetting and elimination disorders
Others that begin in childhood persist in a stable form e.g. autism spectrum disorder and intellectual developmental disorder

A

40% of children with autism have ODD as a comorbidity
Repeatedly argumentative and defiant, irritable and sometimes vindictive
Frequent arguing, loss of temper, displays of anger and resentment on a daily basis
Ignore adult requests and rules, deliberately try to annoy people and blame others for mistakes
Essentially all rooted around a FIGHT AGAINST BEING CONTROLLED, persisting despite reasonable parenting strategies

Q

What are the 2 main theories for why ODD develops?

A

Developmental theory - problems start in toddlers, trouble learning to be independent from an attachment figure, behaviour may be normal developmental issues lasting beyond toddler years
Learning theory - negative symptoms of ODD are learned attitudes, mirroring effects of negative reinforcement methods used by parents which increases the ODD behaviours as they allow the child to get what they want i.e. attention

Q

What are key differences between ODD and conduct disorder?

A

The role of CONTROL - kids who are oppositional/defiant will fight against control but kids who have moved into conduct disorder will not only fight control but will also attempt to control others themselves, conning and manipulating them

Severity of ODD according to number of settings behaviours manifest in, while conduct disorder is based on frequency and extent of misconduct

Q

What have many cases of conduct disorder been linked to?

A

Genetic and biological factors such as damage to frontal lobe of brain (may be genetic abnormality or result from brain injury) - dysregulation of cognitive skills such as problem solving and personality
May also inherit personality traits seen in conduct disorder

Q

How can conduct disorder be treated?

A

Most effective before 13 years old, popularly a combination of several approaches:
Sociocultural - family interventions such as parent-child interaction therapy, also school programs and residential treatments in community
Child-focused - cognitive-behavioural e.g. problem solving skills, anger coping skills and assistance with regulation of emotions
Preventative - Greatest potential when started in early childhood, try to change unfavourable social conditions and involve education and engagement of whole family

Q

What are the 3 types of ADHD?

A

Inattention - inattentive, procrastination, hesitation, forgetfulness, doesn’t seem to listen, easily distracted, disorganised
Hyperactivity - Constant motion, fidgety, talks too much, cannot play quietly
Impulsivity - Acts/speaks without thinking, trouble taking turns, cant wait for things, interrupts others

There is also a combined type of ADHD

Q

What do clinicians consider as being the main causes of ADHD?

A

Biological - abnormal dopamine activity and abnormalities in fronto-striatal regions (same circuitry as OCD)
High levels of stress
Family dysfunction

17
Q

Which key brain areas are affected by ADHD?

A

PFC - Intersection for attention, behaviour and emotional responses; in ADHD attention is switched easily
Limbic system -Deficiency of dopamine may result in restlessness, inattention and emotional volatility
Basal ganglia - Inattention or impulsivity
Reticular activating system - dopamine deficiency here causes impulsivity and hyperactivity

18
Q

What are the treatment options for ADHD?

A

Drugs - Ritalin, a very strong stimulant which balances dopamine levels; problems with drug dependence and abuse however
Behavioural - teaching parents and teachers to apply operant conditioning techniques to change behaviour (reward and punishment); most effective when combined with drug therapy in the beginning, until drug can be withdrawn

19
Q

What are the multi-cultural factors involved in diagnosis and treatment of ADHD?

A

African American and Hispanic American children with attentional and activity problems are less likely to be assessed for adhd, and those who do get diagnosed are less likely to receive the most effective treatment such as Ritalin
At least partially these differences are tied to economic issues, and also cultural differences in extent to which parents driven to seek help for the poor school performances characteristic of the condition

20
Q

What are Autism spectrum disorders?

A

Group characterised by impaired social interactions, unusual communication, and inappropriate responses to environmental stimuli
Children with this condition are unresponsive to others, avoid eye contact, struggle to judge thoughts and emotions of others, and are very repetitive/perseverative in their behaviours and routines

21
Q

How do the brains of autistic children differ from those of typical kids?

A

When shown pictures of family members, patterns of brain activation are different thus suggesting different brain organisation for fundamental social skill of recognising others
Structural differences including reduced size of corpus callosum and certain cerebellar regions
Fewer amygdala neurons but greater amygdala activation when gazing at faces - brain area for fear! Suggests eye contact avoidance because it is physically aversive for them

22
Q

What does it mean that autistic children struggle with “copy-cat” movements of fingers and body?

A

Particular part of frontal cortex is less active and same area is underactive when try to mimic facial expressions
This hypoactive region contains mirror neurones which are active when an individual makes a hand movement/sees another individual make the same movement; deficits in this region underlying imitation and empathy lead to experience of finding behaviour of others overwhelming –> withdrawal from social relationships

23
Q

When do symptoms of autism usually appear?

A

Very early, usually observable even before 3yrs when child will show more interest in objects than people
Language and engagement problems will offer greatest clues for diagnosis

24
Q

What does high-functioning autism look like?

A

Still experience problems with social interactions and communication, lack of responsiveness and social reciprocity, and restricted interests/activities

25
Q

What forms can the language and communication problems of autism take?

A

Echolia - common speech peculiarity in which they exactly echo phrases spoken by others
Pronominal reversal - confusion of pronouns

26
Q

What is Asperger’s?

A

Previously considered a distinct disorder, individuals simply now receive a diagnosis of autism spectrum disorder but of milder severity and high function
Similar difficulties in social cognitive processing but language skills are normally strong and while reading emotions is a challenge they can classify objects and note details well

27
Q

What are some potential psychological, sociocultural and biological causes of autism?

A

Psych - central perceptual/cognitive disturbance leads to failure to develop theory of mind
Socio - high degree of family dysfunction and environmental stress
Bio - genetic component is possible (small contributions from several genes), prevalence high among twins, specific bio abnormalities found in cerebellum (remember this area is involved in fine motor control and supports cognition)

28
Q

What is the aim of ASD treatment?

A

Help individuals to adapt better to their environment, no known treatment can actually totally reverse the autistic pattern

29
Q

How can CBT be used to treat ASD?

A

Teach new and appropriate behaviours, including speech and social skills, while also reducing negative behaviours
Modelling and operant conditioning used
Most effective when started early

30
Q

What is communication training for ASD?

A

Even with intense behavioural treatment, half remain speechless so can be taught alternative methods such as sign language and sign supported speech, and augmentative communication systems such as communication boards

31
Q

What are three further treatment options for ASD?

A

Parent training - trained to apply behavioural techniques at home, and also help to deal with own emotions and needs
Community integration - home-based and school-based programs emphasising self-help and living, social and work skills. Greater numbers of group homes and sheltered workshops
Psychotropic drugs and certain vitamins can help when combined with other approaches
