Symptoms Repetitive behaviours
performed according to rigid rules
Behaviours/ mental acts are aimed at reducing stress/ preventing a dreaded situation/ event
Compulsion causes distress
OCD: Prevalence
General population: 2.5% Szatmari et.al. (1989): 8-10% of AS/
HFA, 5% in control group Other studies show that OCD can
continue into adulthood
OCD: Vulnerability
Psychological differences (ToM, central executive dysfunction, central coherence)
Boredom/ Lack of structure Differences in sensory experiences Misinterpretation of communication Social misunderstandings
OCD: Signals
Repetitive behaviours lead to distress Repetitive behaviours are not stereotypic,

Professional Medication CBT Behavioural
treatments
Parents/ Carers Encourage to
communicate feelings
Adjust environment Sensory
awareness Low arousal
Attention Deficit Hyperactivity Disorder (ADHD) Definition Persistent pattern of
inattention/ hyperactivity-impulsivity
Impairment from symptoms must be across two settings
Clear interference with developmentally appropriate functioning
Symptoms Disruptive/ aggressive
behaviour Constantly “on the go”/
fidgeting Disregard for
consequences?! Inability to finish tasks “Silly” mistakes Dislike for activities
requiring mental effort/ organizational demands
ADHD: Prevalence
3-7% in school-aged children Variety of studies: 50%-66% PDDNOS almost always present as
comorbid condition
Ghaziuddin et.al. , 1992
ADHD: Vulnerability
Psychological differences (sequencing, anticipating consequences; what is “finish” and when?)
Sensory Issues Difficulties filtering Need to work things out cognitively (not
“naturally”) Misunderstandings/ misinterpretation
ADHD: Signals
Many “signals” are part of the presentation of ASDs
Where is the “cut-off”?
ADHD: Treatment Options
Professionals Medication
Parents/ Carers Consistent
approaches
Seeking Professional Help
GP – first point of contact, referral CMHT – have an obligation to treat
individuals affected by enduring mental health problems, regardless of ASD diagnosis
Care Manager/ LD Teams – Care co-ordination includes referral to professionals
