Agitation and Aggression
Peter Della Bella, MD
What is Agitation?
An inability to cope
causing distress…
and losing control
Precursors: Irritability, anxiety, fatigue…
The worry: add a trigger and…
What is Aggression?
(Latin) Attack
Premeditated vs. loss of impulse control
Understanding the Roots of
Agitation and Aggression
Roots of Irritability & Agitation
- the Fight or Flight Response

Roots of Agitation and Aggression
• Survival instinct
(“Boxed into a corner”)
• Pain/physical discomfort
(sensory integration)
• Psychic discomfort
(stress, change, frustration)

What do you do?
• Survival instinct…….. take care of the threat
• Treat sources of physical discomfort, side effects… proper
medical evaluation
sensory
integration principles
• Treat sources of psychic discomfort…..
soften the blow of change
address stress (sleep, food, downtime, fun)

When do you use meds?
• When there are underlying biological factors.

SSRIs:
Fluoxetine

Citalopram/
Escitalopram
What are the pros and cons
of using medications?

Attention Deficit and Hyperactivity
David Grodberg, MD
ADHD SYMPTOMS IN ASD
• DSM-IV TR prohibits diagnosis of ADHD and ASD in the same
individual
• Clinic based surveys indicate that Sx c/w ADHD present in 4178% of children with ASD
ADHD SYMPTOMS IN ASD
• Asperger’s Disorder, PDD-NOS who meet full criteria for
ADHD
• Autistic Disorder with ADHD-like symptoms, which are part of
core features of autism
• Autistic Disorder with increased motor activity, impulsivity,
inattention
ADHD SYMPTOMS IN ASD
• Inattention to social stimuli but good sustained focus on
interests or objects. NOT ADHD.
• Hyperactivity as a manifestation of motor stereotypy, social
anxiety, agitation, or medication side effects. NOT ADHD
TREATMENT OF ADHD
SYMPTOMS IN ASD
• Strongest evidence: methylphenidate
– 2 placebo-controlled trials
– retrospective and prospective effectiveness
study
Methylphenidate
Increases NE and DA by blocking reuptake
Methylphenidate
ASD+ADHD tolerated stimulants generally well
ASD+ADHD had dysphoria and obsessionality
- initiate methylphenidate in ASD at lower dose
and increase dose slowly with frequent
monitoring for side effects
TREATMENT OF ADHD
SYMPTOMS IN ASD
• Moderate Level Evidence: guanfacine
– chart review study
– small open-label trial
• Moderate Level Evidence: atomoxetine
– small open label study
– small placebo controlled study
Guanfacine
Alpha 2A agonist. Enhances prefrontal cortical function
Atomoxetine
Increases NE and DA in prefrontal cortex.
TREATMENT OF ADHD
SYMPTOMS IN ASD
• Weak Support: clonidine, donepezil
– very small studies
Clonidine
Nonselective alpha2 agonist. More sedating/hypotensive.
Donepezil
Acetyl Cholinesterase inhibitor
SUMMARY
• Children with ADHD symptoms and ASD are
difficult to treat
• stimulants (methylphenidate), atomoxetine,
alpha-agonists are effective
• SSRIs and atypical neuroleptics are used to
address other types of symptoms
CLINICAL PEARLS
• If a child with ADHD is referred with poor response to
meds and/or significant side effects (anxiety, stereotypy,
aggression) - look for evidence of previously unrecognized ASD
• If a stimulant is helpful but side effects of anxiety emerge,
can switch to atomoxetine or add SSRI.
• Monitor closely for behavioral disinhibition
– hyperactivity, impulsivity, new odd/disorganized behavior, SI.

Anxiety and Repetitive Behaviors
Alexander Kolevzon, MD
Repetitive Behaviors
A preoccupation with stereotyped and restricted
patterns of interest
Inflexibility in adhering to routines and rituals
Stereotyped and repetitive motor mannerisms
Persistent preoccupation with parts of objects
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)
Repetitive Behaviors
Lower Order (motor/sensory) Higher Order (compulsive)
Repetitive self-injury
Motor stereotypies
Sniffing/mouthing objects
Touching
Tapping
Rubbing
Insistence on sameness
Ritualistic behavior
Circumscribed interests &
preoccupation
Repetitive Behaviors
Lower Order (motor/sensory) Higher Order (compulsive)
Hoarding
Obsessions
Anagnostou et al, 2005
Serotonin System
Critical to neurodevelopment
Directs neuronal growth,
proliferation, differentiation
Widely expressed in
emotional centers of
brain

Novel Therapeutics - Oxytocin
Widely distributed in Central Nervous System;
especially emotional centers
Peripheral release is important for delivery and
lactation
Central release is important for social cognition
(recognition and memory); trust; social
attachment; maternal bonding

 need to know
 repeating
 ordering
 need to tell
 self-injury
 touching
