Background: Yoga originated in the territory of modern India more than 3,000 years ago uses techniques for working with the musculoskeletal system, cardiorespiratory system, and attention. Currently, the effectiveness and safety of yoga in patients with various neurological disorders, including multiple sclerosis (MS), is of interest to many scientists and clinicians.

Purpose: The main aim of this study is to examine the effect of yoga on symptoms and quality of life in patients with MS vs physical therapy (exercise therapy) and no exercise.

Methods: The patients were randomly assigned to three groups (yoga, physical therapy (PT), or waiting list). After 12 weeks of regular exercises (or the absence of them), the effect of yoga and PT on the functional status and quality of life of patients were evaluated. The data were collected during the patients' two visits to the study center - before the start of the study and at the end of the 12-week period. The in-person examination included a doctor's assessment of the Expanded Disability Status Scale (EDSS), the SF-36 quality of life questionnaire, the fatigue scale, the Berg balance scale, and the 6-min walking test.

Results: A total of 36 patients finished the clinical study: thirty women and six men. There was no statistically significant difference between the groups in terms of improvement in MS symptoms as measured by the balance, walking test, and fatigue scales. However, in the analysis of eight criteria of SF-36 quality-of-life questionnaire by the covariation analysis, statistically significant differences were found in favor of the yoga group in terms of physical functioning (PF) (p = .003), life activity (VT) (p < .001), mental health (MH) (p = 013), and social functioning (SF) (p = .028).

Conclusion: Thus, regular yoga classes under the guidance of qualified staff are a promising method of non-drug rehabilitation of patients with MS with motor disorders.

Background: Segmentation and morphometric measurement of brain tissue and regions from non-invasive magnetic resonance images have clinical and research applications. Several software tools and models have been developed by different research groups which are increasingly used for segmentation and morphometric measurements. Variability in results has been observed in the imaging data processed with different neuroimaging pipelines which have increased the focus on standardization.

Purpose: The availability of several tools and models for brain morphometry poses challenges as an analysis done on the same set of data using different sets of tools and pipelines may result in different results and interpretations and there is a need for understanding the reliability and accuracy of such models.

Methods: T1-weighted (T1-w) brain volumes from the publicly available OASIS3 dataset have been analysed using recent versions of FreeSurfer, FSL-FAST, CAT12, and ANTs pipelines. grey matter (GM), white matter (WM), and estimated total intracranial volume (eTIV) have been extracted and compared for inter-method variability and accuracy.

Results: All four methods are consistent and strongly reproducible in their measurement across subjects however there is a significant degree of variability between these methods.

Conclusion: CAT12 and FreeSurfer methods have the highest degree of agreement in tissue class segmentation and are most reproducible compared to others.

Background: Headache is an extremely common symptom of the general outpatient department and also the headache clinic, with prevalence of 48.9% in the general population. None has ever experienced headache in life time. Headache is seen in 1 patient out of 10 general practitioner (GP) consultations, 1 referral out of 3 is headache in neurology OPD, and 1 in 5 of all emergency medical admissions. Of all headaches, around 98% constitute primary headache: migraine without aura, tension headache, and cluster headache. With advancement in various drug modalities, certain headache forms respond less well to the regular approved medications, and some headaches are complicated by the analgesic itself. Steroids have been tried in many subtypes of headache, especially in primary forms of headache with dysautonomia, headache with trigeminal pathway activation and disinhibition, and in certain medication-culprit headaches. This subgroup of headaches is almost a challenge in an emergency for the headache expert as well. So, we need to assess the role of steroids in less well-responsive headaches.

Summary: Current reviewed evidence on the role of steroids in primary headache suggests that steroids have a role in status migrainosus and medication overuse headache when used in the mentioned and monitored manner. Consideration and further exploration of its role in other primary headaches may reveal insight into steroid efficacy as a treatment modality in various subtypes of headache.

Key message: Steroids, when used cautiously in specifically selected primary headaches under supervision, proved miraculous where other modalities failed.

Background: Stress can affect the morphology and synaptic organization of the telencephalon. These structural changes at the cellular level can lead to the development of various psychopathologies.

Purpose: Given that the telencephalon plays a major role in stress responses, the current study aimed to investigate the role of Spirulina platensis as a neuroprotectant supplement in the early life of zebrafish in averting the alteration of synapse morphology in the telencephalon caused by chronic unpredictable stress (CUS) in the later stage.

Methods: 5dpf larvae were divided into two groups: one group was fed with a commercial fish diet and a second group with a 1% Spirulina-supplemented diet for 90 days. After 90 days, the adult zebrafish were exposed to CUS with different chronic stressors for 15 days. The synaptic plasticity was evaluated by morphometric analysis of synapse in telencephalon of zebrafish by transmission electron microscopy.

Results: The ultrastructural study demonstrated the protective role of Spirulina in the CUS model as no significant alterations in the length of the active zone, postsynaptic density, and synaptic cleft were observed as compared to the control group in the CUS model.

Conclusion: Thus, suggesting that the Spirulina supplementation can avert the remodeling effect of stress on synapse ultrastructure.

Background: Obsessive-compulsive disorder (OCD) is considered frequent, unnecessary thoughts that lead to repetitive actions to lessen the apprehension provoked by thoughts; this repetitive sequence may further influence trouble in one's daily activities. The remedial procedure for OCD includes medication (such as SSRIs, anxiolytics, and antidepressants) with psychotherapy [such as cognitive behavioral therapy (CBT) and exposure response prevention (ERP)]. Previous investigations indicated that regardless of the trend of adopting CBT and ERP to treat OCD, only around half of the patients experienced a full reduction in symptoms.

Purpose: The ERP component in CBT has been termed as a challenging treatment as it contains threatening anxiety-provoking indications, and it has been reflected that between 25-30% of OCD patients reject the ERP treatment, and the refusal and dropout rates for ERP in OCD are higher than other interventions. Thus, in the present investigation, researchers developed a proposed therapy that includes neuropsychoeducation, intrinsic motivation, and metaphoric content integrated with CBT in addition to regular pharmacological management to treat OCD patients and validated the efficacy of the proposed therapy through psychometric ratings (Y-BOCS).

Method: In this pilot study, 10 cases of OCD received a 12-week proposed therapy program. The primary outcome was the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), which was assessed at baseline and post-treatment.

Results: The present study's results revealed a significant decrease in scores on the obsessions and compulsions domains and overall total scores on Y-BOCS among OCD patients.

Conclusion: The findings show that this proposed therapy, which includes neuropsychoeducation, intrinsic motivation, and metaphors contents integrated with CBT in combination with pharmacological management, is effective in the treatment of OCD. Therefore, the proposed therapy may be beneficial in the treatment of OCD. It has far-reaching implications in the areas of clinical, psychiatry, and mental health.
