Background: To evaluate the eligibility and feasibility of the "Voice Modules in Narcology" (VMIN) program.

Material And Methods: We developed a computer program to screen for risky alcohol or drug use, utilizing an interactive voice assistant as a motivational component. Given the low detection of such risks during population health examinations and medical check-ups, this program could allow the primary healthcare sector to expand screening coverage for risky alcohol and drug use without additional medical personnel.

Article Synopsis
  • Alzheimer's disease (AD) is a major global health concern with limited treatment options, leading researchers to investigate non-invasive therapies like repetitive transcranial magnetic stimulation (rTMS) to improve cognitive function in patients.
  • A systematic review and meta-analysis of 22 studies found that high-frequency rTMS, especially targeting the dorsolateral prefrontal cortex, significantly enhanced cognitive abilities in AD patients with a moderate effect size.
  • While the findings are promising, they also revealed substantial variability among studies and potential publication bias, indicating the need for further investigation to optimize rTMS treatment parameters.

Presented clinical observation of anti-NMDA-receptor encephalitis, which was first described in 2007, is rare and to date has not been sufficiently studied. The disease often manifests with psychopathological symptoms and catatonia, so patients are transferred into a mental healthcare institution and often require intensive care and resuscitation, due to the development of life-threatening respiratory and hemodynamic disorders. Diagnosis is based on detection of autoantibodies to the NR1- and NR2 subunits of the glutamate NMDA receptor in blood serum and cerebrospinal fluid.

Article Synopsis
  • * Researchers focused on modifiable risk factors, finding that habits like excessive internet use (doom-scrolling), disrupted sleep patterns, and changes to daily routines were linked to increased anxiety scores.
  • * The findings suggest that by managing internet consumption, regulating sleep, and maintaining regular daily activities, individuals may reduce their risk of developing anxiety disorders during prolonged stress, such as that caused by the pandemic.

Selective and progressive death of neurons is a characteristic feature of the process of neurodegeneration and leads to corresponding neuronal dysfunctions. Neurodegenerative diseases represent a heterogeneous group of clinically distinct disorders with similar molecular mechanisms of pathogenesis. They are based on the processes of abnormal aggregation of proteins, the formation of fibrillary insoluble structures and their deposition in the form of histopathological inclusions in the tissues of the nervous system.

Background: Spinal muscular atrophy (SMA) is a rare genetic disorder, in which, for the common childhood onset forms, loss of function of the SMA 5q gene leads to disability and death before adulthood. Symptomatic treatment focusses on respiratory and nutritional support, and physical therapy, but there is little consideration of psychiatric manifestations of SMA. The aim of this study was to explore blood biomarker levels, electromyography (EMG) data, and clinical manifestations, including psychiatric impairments, in patients with SMA 5q.

Background: Depression is a common mental illness, with around 280 million people suffering from depression worldwide. At present, the main way to quantify the severity of depression is through psychometric scales, which entail subjectivity on the part of both patient and clinician. In the last few years, deep (machine) learning is emerging as a more objective approach for measuring depression severity.

Background: Electroconvulsive therapy (ECT) is one of the most effective treatments for depressive disorders. However, ECT has a number of limitations, such as significant side effects in the neurocognitive domain and the requirement for general anesthesia. Transcranial magnetic stimulation (TMS) is an intervention that applies electric stimulation to the brain without causing convulsions, thus representing an attractive alternative to ECT.

Schizophrenia (Sch) is a severe and widespread mental disorder. Antipsychotics (APs) of the first and new generations as the first-line treatment of Sch are not effective in about a third of cases and are also unable to treat negative symptoms and cognitive deficits of schizophrenics. This explains the search for new therapeutic strategies for a disease-modifying therapy for treatment-resistant Sch (TRS).

Among neurological adverse reactions in patients with schizophrenia treated with antipsychotics (APs), drug-induced parkinsonism (DIP) is the most common motility disorder caused by drugs affecting dopamine receptors. One of the causes of DIP is the disruption of neurotransmitter interactions that regulate the signaling pathways of the dopaminergic, cholinergic, GABAergic, adenosinergic, endocannabinoid, and other neurotransmitter systems. Presently, the development mechanisms remain poorly understood despite the presence of the considered theories of DIP pathogenesis.

An original hybrid method for three-dimensional (3D) shaping of micro- and nanostructures by direct imprinting of lithographically patterned metal 2D-elements on a polymer substrate is proposed. The technological features of the method are demonstrated by transforming Au micro/nanostrip arrays into 3D half-turn helices. The metasurface formed by an array of 3D half-turn Au microhelices in the surface layer of a polymer substrate rotates the polarization plane of transmitted 3 THz radiation through an angle in excess of 50°.
