Last update about 20 years ago.

Goal: improve accuracy of diagnosis

Risk: misdiagnosis/ over diagnosis/ medicalization of normal behavior

Changes: 

  • single axis not multi-axis format
  • Simplify use by clinician
  • Age/ gender/ culture are now considered factors when making a diagnosis
  • Just starting the science of psychiatry (3 sections: introduction/ outline of categorical diagnosis/ conditions that require further research)
  • “Unclear what we know and what we do not know”

 

Notable Changes            

Neurocognitive Disorders: Major neurocognitive disorder (dementia): memory impairment is not essential/ ex. frontotemporal dementia has personality changes early and memory changes later.

Mild neurocognitive disorder: mild cognitive decline beyond normal forgetfulness of aging. 1-2 SD below norm on NC testing.

Intellectual Disabilities:  

  • MR is removed
  • Based on cognitive and adaptive function
  • Mild/ moderate/ severe/ profound are eliminated
  • Specifiers are now used
  • Severity is determined by adaptive functioning not IQ score

 

Autism Spectrum Disorder:     

  • Replaces PDD: AD/ AS/ CDD/ Rett’s syndrome/ PDD(NOS)
  • autistic disorder/ PDD(NOS)/ AS are joined
  • Specifiers: language delay or intellectual disability
  • Primary focus is on strengths and weaknesses
  • Mild/ moderate/ severe are eliminated
  • Defined in terms of level of support required
  • New specifier: ASD is associated with a known medical/ genetic/ environmental factor. (ex: FAS/ Fragile X syndrome/ epilepsy)
  • Benefits: improve diagnosis in girls
  • Unsolved: minority access to services delays diagnosis
  • Dual diagnosis of ADHD and ASD now allowed
  • 2 domains:         
    • deficits in social communication and social interaction
    • RR (restricted repetitive) behaviors, interests and activities

 

Social Communication Disorder               

  • new diagnostic category/ outside of ASD
  • Lack RR behaviors
  • Children with severe ADHD and social skill deficits
  • Allows a new group of patients

 

Somatic Symptom Disorders  

  • Somatoform diagnosis is eliminated: this focused on medically unexplained symptoms.
  • Somatic symptom disorder: medically unexplained is not central to this diagnosis. (lowers the risk of alienating patients by imaginary context)
  • Focus on symptoms lasting longer than 6 months that are associated with disproportionate thoughts, feelings and behaviors such as extreme anxiety.

 

ADHD

  • Reverse of most psychiatric conditions that are defined in adults and modified for use in children.
  • Limits social, academic or occupational functioning
  • At least six symptoms from either or both of two symptom domains: inattention and hyperactivity/ impulsivity.  Over 17 years need only five symptoms.
  • Inattention:  Careless mistakes/ difficulty with sustained attention/ not listen/ not follow instructions/ difficulty organizing/ poor sustained tasks/ loses things/ easily distracted/ forgetful.
  • Hyperactivity and Impulsivity:  Not due to oppositional behavior/ defiance/ hostility or lack of understanding instructions.  Fidgets, squirms or taps/ leaves seat/ runs and climbs when not appropriate/ lack of quiet play/ unable sit still/ talks excessively/ blurts out answers/ difficulty waiting turn/ interrupts or intrudes.
  • Several symptoms must be seen in each setting rather than more than one setting involved as the past criteria.
  • Levels: mild (few symptoms and minor impairment)/ moderate (between mild and severe)/ severe (many symptoms and marked impairment in social or occupational functioning)
  • Age of onset increased to 12 years from age 7 years since some issues with inattention do not manifest until a child is older.
  • 314.00 Predominantly inattentive
  • 314.01 Combined
  • 314.01 Predominantly hyperactive/ impulsive

 

Communication Disorders

  • language disorder: previously called expressive and mixed receptive-expressive language disorders.
  • Speech sound disorder: previously called phonological disorder.
  • Childhood-onset fluency disorder: previously called stuttering

 

Specific Learning Disorder    

  • Includes reading disorder/ mathematics disorder/ disorder of written expression/ learning disorder (NOS).
  • Coded specifiers for the deficit types
