1: Autism + Somatization Disorders Flashcards
definition of autism spectrum disorder
complex disorders of brain development - characterized by poor social interaction, verbal and nonverbal communication and repetitive behaviors
-Sx must be present in early development but may not manifest until social demands exceed limited capacities
which gender is more likely to be affected by autism?
boys
Clinical features of autism
- language delay (expressive and/or receptive)
- impaired social communication and interaction
- lack of reciprocity
- deficit in joint attention
- impaired nonverbal communication (gaze especially)
- impaired social relationships
- restricted, repetitive behaviors
- hand flapping, self injurious behaviors
- difficulty w/ schedule change
- restricted interests
- sensory perception issues
- sometimes intellectual impairment
- motor delays (toe walking, abnormal gait - clumsy)
- “savant” skills
timing of Sx in autism
- onset usually noted when 2 y/o
- may be present as early as 6 mo
- may not become apparent until later when social demands exceed capabilities
screening instrument for autism
M-CHAT (questionnaire)
diagnosis of autism
-Hx: FHx - autism, language delay, MR, tuberous sclerosis, seizure disorders
-PE: growth (ht, wt, head circum, BMI);
skin (Woods lamp eval for hypopigmented macules of
Tuberous sclerosis);
neuro (focal neuro signs may stimulate imaging)
-Test: vision, hearing, lead, language, OT and PT eval if motor delay
definition of illness vs. disease
illness: response of individual or family to Sx
disease: pathophysiologic process associated with documentable physical lesion(s)
definition of somatization vs. somatoform illness
somatization: tendency to experience and communicate psychological or emotional distress as somatic (physical) sx
somatoform illness: produces significant dysfunction in patient’s life
general about somatoform disorders (somatic sx disorder and related)
- characterized by physical sx that cause significant distress and impairment
- NOT caused by direct effects of a substance or by another mental disorder
- if another medical condition is present, the physical sx are far in excess of what should be expected
factitious disorder
sx are produced or feigned in order to appear ill, with NO PERCEIVABLE BENEFIT to patient
malingering disorder
sx are produced or feigned in response to an EXTERNAL INCENTIVE
why do somatic sx disorders have a challenging patient population?
- chronic, difficult to treat
- high utilizers of the medical systems
what are risks associated with somatic sx disorders?
- repetitive, unnecessary diagnostic testing
- invasive medical/surgical workups
- medically induced (iatrogenic) illness
prevalence of somatic sx disorder: higher in what gender?
females
heritability/factors affecting somatic sx disorders?
- genetic and environmental factors
- observed in 10-20% of first degree female relatives of affected patients
- males of these families show an increased risk of antisocial personality disorder and substance abuse disorders (alcohol)
