Proxy measures for the assessment of psychotic and affective symptoms in studies using electronic health records.

Background: There is a lack of standardised psychometric data in electronic health record (EHR)-based research. Proxy measures of symptom severity based on patients' clinical records may be useful surrogates in mental health EHR research.

Aims: This study aimed to validate proxy tools for the short versions of the Positive and Negative Syndrome Scale (PANSS-6), Young Mania Rating Scale (YMRS-6) and Montgomery-Åsberg Depression Rating Scale (MADRS-6).

Clinical Diagnosis of an Autoimmune Encephalitis Presented as a Manic Episode with Psychotic Symptoms: A Case Report.

Paraclinical criteria guide the approach; however, the challenge occurs when there are no detectable autoantibodies in serum or cerebrospinal fluid (CSF).

[Predominant polarity in type-I bipolar patients: Study in an isolated population with a high prevalence of mood disorders].

Introduction: Recent studies have shown that the predominant description of polarity has effects upon early detection and the timely beginning of treatment in patients with bipolar affective disorder (BAD).

Methodology: Cross sectional cut and descriptive study in 101 BAD patients coming from a genetically isolated population from the Colombian Region of Antioquia.

Results: The study covered a population of 101 patients with type-I BAD diagnosis, out of which 57,4% met the criteria for maniac polarity (MP), 10,1% exhibited depressive polarity (DP) and 25,7% were classified with Indefinite Polarity (IP).
