Background: Cognitive remediation therapy (CRT) has proven to be effective in treating cognitive deficits in schizophrenia. The current study aimed to assess the efficacy of CRT on psychotic symptoms and cognitive complaints.
Methods: We contrasted the changes in symptoms and cognitive complaints in patients with schizophrenia and related disorders who received 2 novel CRTs, one targeting mental state attribution, and the other, mental flexibility, compared with a control group given treatment as usual. Twenty-four patients with schizophrenia and related disorders were pseudo-randomly assigned to 1 of 3 groups. Psychotic symptoms and subjective complaints about their cognitive deficits were evaluated twice in each group, before and after therapy. Scores obtained pre- and post-therapy were compared between the groups.
Results: The therapies were well-tolerated by the participants, and no one dropped out of the study. Symptoms decreased after therapy, but not in the control group. The mental flexibility group showed the most improvement. Moreover, patients in this group described a subjective diminution of their cognitive deficits.
Conclusions: Our results demonstrate that CRT can be useful to reduce clinical symptoms while they suggest an impact of CRT on cognitive complaints in patients with schizophrenia.

Schizophrenia is one of the most debilitating mental illnesses affecting any age group. The mechanism and etiology of schizophrenia are extremely complex and multiple signaling pathways recruit genes implicated in the etiology of this disease. While the role of Wnt/β-catenin signaling in this disorder has been verified, the impact of long noncoding RNAs (lncRNAs) associated with this pathway has not been studied in schizophrenia.

Background: Cognitive networks impairments are common in neuropsychiatric disorders like Attention Deficit Hyperactivity Disorder (ADHD), bipolar disorder (BD), and schizophrenia (SZ). While previous research has focused on specific brain regions, the role of the procedural memory as a type of long-term memory to examine cognitive networks impairments in these disorders remains unclear. This study investigates alterations in resting-state functional connectivity (rs-FC) within the procedural memory network to explore brain function associated with cognitive networks in patients with these disorders.

Background: Clozapine is effective for treatment-resistant schizophrenia and bipolar disorder but is often discontinued due to adverse effects. This study compared early clozapine discontinuation rates and reasons in patients with mood and psychotic disorders.
Methods: Data from all individuals with mood or psychotic disorders who initiated clozapine for the first time at the inpatient psychiatric unit of Mayo Clinic, Rochester, Minnesota, between 2014 and 2022 were retrospectively analyzed.
