Study on the final diagnosis of nervous system diseases with psychiatric symptoms as manifestation onset.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesMisdiagnosis of psychiatric disorders can lead to waste of medical resources and delay of treatment after correct diagnosis. Identify organic neurological disorders misdiagnosed as psychiatric disorders, and broaden the spectrum of disorders with psychiatric symptoms as the first or main manifestation.
methodsThis is a retrospective cross-sectional study. From January 1, 2020 to December 1, 2023. Patients in the psychiatric outpatient and inpatient department of the First Affiliated Hospital of China Medical University, Liaoning Province. Inclusion criteria were adults (age >18 years) with a previously diagnosed psychiatric disorder. A total of 298 patients were diagnosed with psychiatric disorders, of which 197 patients with only diagnosed psychiatric disorders and effective symptomatic treatment were excluded. Collect data on clinical features, tests, examinations, meeting criteria for psychiatric disorders, and final diagnosis.
resultsA total of 101 patients initially diagnosed with psychiatric disorders at our hospital met the psychiatric diagnostic criteria, with a median (IQR) age of 46 years (18-69), and 78% were women. Following symptomatic treatment, disease progression prompted a reassessment with additional medical history, special laboratory tests, and imaging sequences, revealing clear abnormalities. Correct diagnoses comprised autoimmune encephalitis (LGI1) (20%), autoimmune encephalitis (NMDAR) (17%), autoimmune encephalitis (GABABR) (16%), and others: GFAP 2%, mGLUR5 1%, GAD65 1% (4%), herpes simplex virus encephalitis (22%), Creutzfeldt-Jakob disease (3%), N2O abuse (14%), syphilis (3%), and Hashimoto's encephalopathy (2%). DISCUSSION: Psychiatric disorders have diverse etiologies, and advances in medical technology have broadened the spectrum of diseases manifesting with psychiatric symptoms. Recognizing the biological bases of many psychiatric symptoms allows for timely, effective treatments. Psychiatric diagnoses carry much more stigma than Neurology diagnosis. Patients who previously met the diagnostic criteria for psychiatric disorders may now have an organic neurologic etiology to be found. Red flags for neurology diagnoses include ineffective symptomatic treatment and worsening clinical symptoms. Hence, early differentiation between psychiatric and organic neurological diseases is essential. Utilizing special MRI sequences, laboratory tests, cerebrospinal fluid examinations, EEG and specific methods helps reduce misdiagnosis, prevent treatment delays, and optimize medical resource usage. Accurate diagnosis of psychiatric disorders is essential to minimize missed diagnosis and misdiagnosis and to improve the prognosis of organic neurological disorders with psychiatric symptoms.
