Dr. Jiang Weimin
Hallucinations caused by influenza B fever are a type of delirious mental state. Clinical symptoms include dizziness, agitation, fear, anxiety, memory impairment, seizures, insomnia, and may also involve psychotic symptoms. The underlying mechanism primarily involves high fever induced by influenza B, which elevates the temperature of the cerebrospinal fluid, thereby affecting neuronal conduction in the brain, leading to neural excitation and resulting in a series of mental and behavioral abnormalities. To treat hallucinations caused by influenza B fever, doctors will develop an individualized treatment plan based on the patient's specific condition. First, controlling the high fever and regulating body temperature is essential. Then, appropriate medications such as antipsychotics and anti-anxiety drugs are administered. Finally, psychological counseling is provided to help patients adjust their mindset, build psychological resilience, and relieve emotional tension. Hallucinations caused by influenza B fever can be effectively managed with proper treatment; however, patients should seek medical attention promptly to prevent worsening of the condition.
