Schizophrenia: Diagnostic Tests

Obligatory medical device diagnostics.

  • Encephalogram (EEG; recording of the brain‘s electrical activity) – to rule out structural brain changes.
  • Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) – to exclude cardiac arrhythmias.
  • Magnetic resonance imaging of the skull (cranial MRI, cranial MRI or cMRI).
    • For initial manifestation of schizophrenia [guidelines: S3 guideline].
    • In suspected brain changes such as tumor, inflammation, etc.
  • Computed tomography of the skull (cranial CT, cranial CT or cCT) – when MRI is not available.

Further notes

  • The optical coherence tomography (OCT) method could potentially improve the diagnosis of schizophrenia. Compared with healthy subjects, this examination method showed a greatly reduced thickness and volume of almost all measured retinal layersNote: Optical coherence tomography (OCT) is one of the imaging techniques and is used in ophthalmology to examine the retina (retina), vitreous, and optic nerve (optic nerve). It is a non-invasive, non-contact method of producing optical, two-dimensional cross-sectional images that have high spatial resolution.
