Diagnosis of Infectious or Inflammatory Psychosyndromes

Before an outline of the process of diagnosis and differential diagnosis in infectious and/or inflammatory psy-chosyndromes is given, a more general overview onto the approach to organic psychosyndromes seems useful, because in both entities similar principles of causality conclusion are applied. Correlation does not demonstrate causality. Therefore the principles and consensus recommendations, and limitations of causal inference to categorize psychosyndromes as be-ing ‘organic’, is to be discussed in detail.
