Psychotic fever isn't a single, formally defined medical condition. Instead, it refers to the occurrence of psychosis symptoms alongside a fever. The psychosis can manifest as hallucinations (seeing or hearing things that aren't there), delusions (false beliefs), disorganized thinking, and altered behavior. The fever itself may be caused by various underlying infections or medical conditions. It's crucial to understand that the fever is not causing the psychosis directly, but rather, both symptoms might stem from a shared underlying issue.
Understanding the Connection Between Fever and Psychosis
Several studies and articles highlight the association between fever and psychotic episodes. These instances show that fever can accompany a psychotic episode, making the diagnosis of the underlying cause challenging. The fever may be a symptom of an infection triggering the psychosis (such as in cases of encephalitis or Brucellosis), or both symptoms may result from an unrelated underlying medical or neurological issue. For example, a patient might experience a psychotic break due to a separate disorder, with a concurrent fever stemming from an unrelated infection.

Examples of Underlying Causes: Infections (e.g., Brucellosis, encephalitis), autoimmune diseases, metabolic disorders, and even the side effects of certain medications.

Important Note: Fever hallucinations, while sometimes occurring alongside fevers, are typically non-dangerous in themselves. They are different from a full-blown psychotic episode triggered by underlying conditions.
Historically, inducing fever (pyretotherapy) was used as a treatment for psychosis. Although now largely outdated, this approach highlights the perceived (and sometimes demonstrable) link between altered body temperature and mental state. However, this does not equate to fever itself causing psychosis.
Differentiating Fever-Related Psychosis from Other Psychoses
It is essential to distinguish between psychosis primarily related to fever and other forms of psychosis. In many cases, the fever is a symptom of a primary illness, whereas in other situations, a psychotic episode might arise independently, coinciding with a fever from a different source. Accurate diagnosis requires thorough medical evaluation to identify the underlying cause of both the fever and the psychotic symptoms.
The articles referenced support the concept of fever being associated with psychosis, with the fever possibly acting as a symptom of the underlying illness or a co-occurring factor. However, none define a specific medical condition called "psychotic fever."
