Abstract Acute Inflammatory Demyelinating Polyneuropathy (AIDP) is acknowledged as the most prevalent variant of Guillain-Barre syndrome, though diagnosing it can be intricate. Patients often exhibit symptoms that might be misconstrued as psychosomatic, adding complexity to the diagnostic process. This case involves a patient who presented with insomnia, tremors, and restlessness, without any associated dreams. Unlike the conventional presentation of AIDP, this atypical manifestation underscores the challenges in identifying Guillain-Barre syndrome. The case report delves into this unique presentation, elucidates the diagnostic journey for Guillain-Barre syndrome, briefly reviews the connection between psychosis and psychosomatic complaints in Guillain-Barre patients, and emphasizes the imperative of thorough evaluation, bearing in mind that psychosomatic disorders should only be considered after excluding other potential causes.
