Article Abstract
Schizophreniform syndromes in combination with autoimmune thyroiditis and increased serum thyroid antibodies lead healthcare practitioners to consider a diagnosis of Hashimoto's encephalopathy. To detect specific biomarkers, the authors analyzed whether intrathecal antithyroid antibody synthesis occurred in a subgroup of schizophreniform patients. In doing so, the authors analyzed thyroid antibodies in paired cerebrospinal fluid and serum samples from 100 schizophreniform patients. Increased antibody indices (AIs) for antithyroid peroxidase or antithyroglobulin autoantibodies in 13 schizophreniform patients were found. AIs were increased in 68% of the seropositive patients. These findings support the hypothesis that autoimmune processes may contribute to the pathophysiology in these patients.

Extrapyramidal symptoms (EPS) may occur as a primary feature in patients with first-episode psychosis with no or brief exposure to antipsychotics (AP). We aimed to analyse the prevalence of EPS in naïve and quasi-naïve first episode schizophrenia spectrum disorders (FES), their demographic and clinical correlates at baseline, and their association with clinical outcomes during follow-up. We analysed data from the OPTiMiSE trial, Phase 1 (n = 481 participants with FES, aged 18-40).

Fahr's disease (FD) is a rare neurological disorder that causes abnormal, symmetrical, and bilateral calcification of the basal ganglia and other brain regions. Psychiatric symptoms are one of the many manifestations that guide FD diagnosis, with most usually occurring by ages 30-60 years. Herein, we report an incidental finding of bilateral basal ganglia calcification in a 14-year-old male teenager presenting psychotic characteristics, including schizophreniform and manic-like symptoms, who was initially investigated for mycoplasma infection.

Objectives: We analyzed the genotypic and phenotypic features of patients with psychosis of epilepsy (POE).
Methods: Patients with POE recruited to an epilepsy genetics research program underwent phenotyping and genetic analysis. The latter included screening for rare pathogenic variants in epilepsy genes, and polygenic risk score (PRS) calculation for common risk variants associated with schizophrenia.
