Childhood Disorders
Intellectual Disability (formerly mental retardation)
Autism Spectrum Disorders
ADHD
Tourette Disorder
Intellectual Disability (formerly mental retardation)
Definition
In order to determine the level of intellectual disability, patients must exhibit deficits in both interllectual functioniong (cognitive abilities) as well as social adaptive functioning (the ability to do daily activites). the disorder is momre frequent in boys, with the highest incidence in school age children.
Mild mental retardation
IQ range:
Level of functioning:
IQ range: 50-55 to 70
Level of functioning: reaches sixth grade level of education, can work and live independently, needs help in difficult or stressful situations
Moderate mental retardation
IQ range:
Level of functioning:
IQ range: 30-4- to 50-55
Level of functioning: reaches second grade level of education, may work with supervision and support, neds help in mildly stressful situations
Severe mental retardation
IQ range:
Level of functioning:
IQ range: 20-25 to 35-40
Level of functioning: little or no speech, very limited abilities to manage self-care
Profound mental retardation
IQ range:
Level of functioning:
IQ range: below 20
Level of functioning: needs continuous care and supervision
Intellectual Disability (formerly mental retardation)
Treatment
Genetic counseling, prenatal care, and safe environements for exptectant mothers
if due to medical conditions, effective treatmeent for disorder
special education to improve level of functioning
behavioral therapy to help reduce negative behaviors
Autism Spectrum Disorders
definition
Autism Spectrum Disorders are characterized by problems in social interactions, and language wthat tend to occur in children yougner than age 3 and impari daily functioning. this diagnosis has replaced autism, Rett’s syndrome, and Asperger’s disorder

Autism Spectrum Disorders
facts
more common in boys
usually seen by 3 months of age
rule out deafness
language deficits, aggression, lack separation anxiety, are withdrawn
Attention Deficit Hyperactivity Disorder
Definition
a disorder characterized by inattention. short attention span, or hyperactivity that is severe enough to interfere with daily functioning in school, home, or work. the sx must be presetn fro more than 6 months and usually appear before the age of 7. the sx may persist into adulthood

Attention Deficit Hyperactivity Disorder
1st line treatment
methylphenidate and dextroamphetamine. side effects include insomaina, decreased appetite, GI disturbances, increased anxiety, and headach. these drugs work well in reducing these sx of inattention and hyperactivity bc they affect the noradrenergic and dopaminergic pathways of attention
Attention Deficit Hyperactivity Disorder
2nd line treatment
atomoxetine, a ne reuptake inhibitor with fewer side effects and less risk of abuse. the alpha-2 agonists clonidine and guanfacine can also be used, because they enhance cognition and attention in the prefrontal cortex.

cyclothymic disorder
mdd with atypical features
mdd with seasonal pattern
bereavement
Major Deppressive Disorder
definition
mood disorders peresent with at least a 2 week course of sx that is a change fromt he perivous level of unctioning. the sx included derpressed mood or anhedionia (absence of pleasure) and 4 others including depressed mood most of the day, weight canges, sleep changes, psychomotor disturbances, fatigue, poor concentrations, and thoughts of death and worthlessness
Major Deppressive Disorder
diagnosis
rule out any medical causes, the nost common of which is hypothyroidism. the mos tcommon neurological assocaitons are Parkinsons diease and neurocognitive disorders
Major Deppressive Disorder
first - line treatment
SSRI such as fluoxetine, paroxetine, sertrlaine, citolopram, or escitalopram. ssris are chosen due their effectiveness and relatively mild side effects, and because they are less toxic in overdoes than other antidepressants
if no effect after 4 weeks, withch to other SSRI
if some improvement is noted, but not ful response, increase the dose of the SSRI
although TCA’s can be sued, their lethal potential militates against routin use
Major Deppressive Disorder
second-line treamtent
SNRIs such as venlafaxine, duloxetine, or desvenlafaxine. side effects include htn and sweating
Major Deppressive Disorder
psychotherapy
such as cognitive therapy has been proven to be effective. the goal of cognitive therapy is to reduce derpession by teaching patients to identify negative congitions and develop positive ways of thinking
ssri’s should not be taken with
mao inhibitors bc they dacuse a dramatic increase in serotonin
pt with depression and neuropathic pain
use duloxetine, since it is approved for both depression and neuropathy
pt with depression who is fearful of wieght gain or sexual side effects or is a smoker tyring to quit
use bupropion, since it has fewer sexual side effects and less wieght fain than SSRIs. may also be used as adjunct or replacement treatment for SSRI-induced sexual side effects. bupropion has been approved for smoking cessation
Mirtazapine

put on antipsychotic, no reason to get lithium level if they are physcially aggressive
