ADHD

Treatment
– Medication
– Psychosocial treatments
ADHD Treatment

Medications

psychoedn

DSM IV criteria
– 8 types of behaviour
– require 4 or more of these lasting at least 6
months

functioning
• Behaviours happen more frequently than would be
typical for the patient’s age and developmental level

oppositional phases
 behaviors occur in patient more
frequently than with peers at same
developmental level

ODD - Epidemiology


more common in males
• 2:1 males:females

onset usually by 8 years of age

substance abuse disorder

Few controlled studies
 Variety of options

– behavior therapy
– family therapy
– parent management training

Treat comorbidities (ADHD)

CD -- Diagnosis

need to have 3 or more of these behaviors in
the previous 12 months, with at least 1 criteria
present in past 6 months
 impairment in functioning
 If >18 y.o., criteria not met for ASPD
 Subtypes
– early (childhood) onset
– late (adolescent) onset
CD -- Subtypes

Childhood-Onset (onset of at least one
criterion prior to age 10 years)
– usually more aggressive, usually male
– poor peer relationships
– these are the ones that are more likely to
go on to Antisocial PD
CD -- Subtypes

Adolescent-Onset (absence of any
criteria prior to age 10 years)
– tends to be less severe
– less aggressive
– better peer relationships
– more often female
– lower male:female ratio
Associated Features
Little empathy
 Little concern for feelings and well being
of others
 Misperceive the intentions of others as
hostile and threatening
 Callous
 Lack remorse or guilt (other than as a
learned response to avoid punishment


Only 3 risk factors have been shown to
be “causal”
– harsh, inconsistent parenting
– poor academic performance
– exposure to parental discord
CD -- Etiology

Combination of genetic and environmental
factors
 Risk for CD is increased in children with
– a biological or adoptive parent with ASPD
– a sibling with CD

Environmental factors
– poor family functioning (poor parenting, marital
discord, child abuse)
– family history of substance abuse,mood d/o,
psychotic d/o, ADHD, LD, CD and Antisocial PD
Antisocial Personality Disorder

Pervasive pattern of disregard for and
violation of the rights of others occurring
since age 15 years

– Failure to conform to social norms with respect to
lawful behaviours – repeatedly performing acts
that are grounds for arrest
– Deceitfulness, repeated lying, use of aliases or
conning others for personal profit or pleasure
– Impulsivity or failure to plan ahead
Antisocial Personality Disorder

sustain consistent work behaviour or honour
financial obligations
– Lack of remorse – being indifferent to or
rationalizing having hurt, mistreated or stolen from
another
Antisocial Personality Disorder
At least 18 years of age
 Evidence of CD, with onset before age
15 years
 Not due to Schizophrenia or Mania

CD -- Course

< 50% of CD have severe and
persistent antisocial problems as adults
CD – Protective Factors
easy temperament
 above average intelligence
 competence at a skill
 a good relationship with at least 2
caregiving adult

CD -- Management

4 treatments that show the most
promise for treating CD based on good
studies that have been replicated
– cognitive problem solving skills training
– parent management training
– family therapy
– multisystemic therapy
CD -- Management

Pharmacological
– to treat comorbid conditions
• ADHD – stimulants
• Depression - SSRIs
• Anxiety - SSRIs
– to treat CD alone
• Impulsivity/Aggression - mood stabilizers,
neuroleptics
Tics





a part of the body moves repeatedly, quickly,
suddenly and uncontrollably
can occur in any body part, such as the face,
shoulders, hands or legs
Sounds that are made involuntarily (such as
throat clearing) are called vocal tics
Most tics are mild and hardly noticeable.
in some cases they are frequent and severe,
and can affect many areas of a child's life.
Tics
5 to 24% of all school age children have
had tics at some stage during this
period
 Tics appear to get worse with emotional
stress and are absent while sleeping.

Transient Tic Disorder






The patient has vocal or motor tics,or both. They can be single
or multiple.
For at least 4 weeks but no longer than 12 consecutive months,
these tics have occurred many times each day, nearly every
day.
These symptoms cause marked distress or materially impair
work, social or personal functioning.
They begin before age 18.
The symptoms are not directly caused by a general medical
condition (such as Huntington's disease or a postviral
encephalitis) or to substance use (such as a CNS stimulant).
The patient has never fulfilled criteria for Tourette’s Disorder or
Chronic Motor or Vocal Tic Disorder
Chronic Tic Disorder






Single or multiple motor or vocal tics, but not both, have been
present at some time during the illness.
The tics occur many times a day nearly every day or
intermittently throughout a period of more than 1 year, and
during this period there was never a tic-free period of more than
3 consecutive months.
The disturbance causes marked distress or significant
impairment in social, occupational, or other important areas of
functioning.
The onset is before age 18 years.
The disturbance is not due to the direct physiological effects of a
substance or a general medical condition
Criteria have never been met for Tourette’s Disorder
Tourette’s Disorder




Both multiple motor and one or more vocal tics have
been present at some time during the illness,
although not necessarily concurrently
The tics occur many times a day (usually in bouts)
nearly every day or intermittently throughout a period
of more than 1 year, and during this period there was
never a tic-free period of more than 3 consecutive
months.
The onset is before age 18 years.
The disturbance is not due to the direct physiological
effects of a substance or a general medical condition.
Treatment

Depends on
– severity,
– the distress it causes to the patient
– the effects the tics have on school or job
performance.

Medication and psychotherapy are used
only when there is substantial
interference with ordinary activities.
Treatment

Neuroleptics
– Pimozide.
– Risperidone.

Other options
– Clonidine
Treatment

Habit-reversal training (HRT)
– Awareness training
• accentuates sensitivity to tic sensations
– Competing response training
• taught a specific response pattern that would
be incompatible with the tic
• replaces the tic behavior with a more
appropriate competing response
Antares is the 15th brightest start in the
sky
 It is more than 1000 light years away

So just try to keep everything in
perspective!!
