- - - - Chronic vs. stationary
      - Improving
      - Congenital (from birth)
      - Progressive/Degenerative
      - Exacerbating/remitting
    - - Acquired
      - Congenital
        (< days post-birth)
      - Developmental
    - - Degenerative (e.g. Parkinson's)
      - Inflammatory (e.g. encephalitis)
      - Toxic-metabolic (e.g. liver failure)
      - Neoplastic (e.g. brainstem tumor)
      - Traumatic (e.g. TBI)
      - Vascular (e.g. ischemic stroke)
  - - - DAB = Darley Aronson Brown classification
      - Speech Disorders classification systems
      - Depends on severity, speech tasks, listener's expertise
- - - - Muscles and temporal relationship
        (EMG, EGG, EMA)
      - Activity in CNS
        (PET, EEG, fMRI)
    - - Between perceptual and acoustic
      - Can be quantified but mostly interpreted
      - e.g. laryngoscopy, videofluroscopy)
