Unmasking herpes encephalitis masquerading as acute psychosis via neuroimaging

Psychosis is a complex mental health condition that can have a profound impact on individuals and their families. It is characterized by a loss of contact with reality, including delusions, hallucinations, and disorganized thinking. While psychosis is most commonly associated with psychiatric disorders such as schizophrenia, it is crucial to consider other potential causes to ensure accurate diagnosis and appropriate treatment. One such often overlooked condition is herpes encephalitis, a viral infection that affects the brain, like in this case where a 22 year old male presented with acute episodes of psychosis which later turned out to be herpes encephalitis diagnosed on MRI (Magnetic Resonance Imaging) of brain screening followed by CSF (Cerebrospinal Fluid) analysis. In this article, we will also discuss herpes encephalitis and explore its role as a differential diagnosis for psychosis.
