OBJECTIVE: The objective was to examine the outcomes of posterior tibial nerve stimulation (PTNS) on bladder, bowel, and sexual health-related quality of life among a cohort of patients with multiple sclerosis (MS) with refractory lower urinary tract symptoms (LUTS).
METHODS: Patients with MS and refractory LUTS were recruited for a prospective, observational study using PTNS to treat their symptoms. Patients underwent 12 weekly 30-min PTNS sessions and bladder, bowel, and sexual symptoms were evaluated at baseline, 3, 12, and 24 months with voiding diaries, visual analog scales (VAS), and validated patient-reported questionnaires, including the American Urological Association Symptom Score (AUA-SS), Neurogenic Bladder Symptom Score (NBSS), Michigan Incontinence Symptom Index (M-ISI), Health Status Questionnaire, Sexual Satisfaction Scale, and Bowel Control Scale.
RESULTS: A total of 23 patients were recruited: 18 started PTNS and 14 completed 3 months of PTNS. Of the 18 who started PTNS, the mean age was 52 years (SD 12), 61% were female, 83% were white, and most patients had relapsing remitting (39%) MS. Baseline (n=18) and 3-month voiding (n=11) outcomes showed no significant change in number of voids or incontinence episodes. The median VAS symptom improvement was 49 (IQR 26.5, 26) and 9 (53%) patients elected for monthly maintenance PTNS. On paired analysis, there was a significant improvement in median change in NBSS, AUA-SS, and M-ISI. There was no significant change in bowel or sexual dysfunction.
CONCLUSIONS: This prospective, observational study of PTNS in patients with MS with refractory LUTS shows improvement in patient-reported bladder outcomes, but not in number of voids per day or bowel or bladder function.

Neurodegenerative diseases (NDDs) are neuronal problems that include the brain and spinal cord and result in loss of sensory and motor dysfunction. Common NDDs include Alzheimer\'s disease (AD), Parkinson\'s disease (PD), Huntington\'s disease (HD), Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS) etc. The occurrence of these diseases increases with age and is one of the challenging problems among elderly people. Though, several scientific research has demonstrated the key pathologies associated with NDDs still the underlying mechanisms and molecular details are not well understood and need to be explored and this poses a lack of effective treatments for NDDs. Several lines of evidence have shown that NDDs have a high prevalence and affect more than a billion individuals globally but still, researchers need to work forward in identifying the best therapeutic target for NDDs. Thus, several researchers are working in the directions to find potential therapeutic targets to alter the disease pathology and treat the diseases. Several steps have been taken to identify the early detection of the disease and drug repurposing for effective treatment of NDDs. Moreover, it is logical that current medications are being evaluated for their efficacy in treating such disorders; therefore, drug repurposing would be an efficient, safe, and cost-effective way in finding out better medication. In the current manuscript we discussed the utilization of drugs that have been repurposed for the treatment of AD, PD, HD, MS, and ALS.

Cognitive impairment in multiple sclerosis (MS) is common and can have negative effects on quality of life. The clinical presentation can be more subtle and insidious. Thus, cognitive impairment is often underrecognized by both persons with MS (PwMS) and clinicians, leading to underestimation disability due to MS. Recent evidence supports that relapses affect cognition in a similar pattern to other physical relapse symptoms and may be the only symptom of a relapse. Regular screening using validated tests for PwMS will improve the care provided and quality of life of PwMS.

Multiple sclerosis (MS) is increasingly understood not only as a white matter disease but also involving both the deep and cortical gray matter (GM). GM pathology in people with MS (pwMS) includes the presence of lesions, leptomeningeal inflammation, atrophy, altered iron concentration, and microstructural changes. Studies using 7T and 3T MR imaging with optimized protocols established that GM damage is a principal driver of disease progression in pwMS. Future work is needed to incorporate the assessment of these GM imaging biomarkers into the clinical workup of pwMS and the assessment of treatment efficacy.

Magnetic resonance imaging is the most sensitive method for detecting inflammatory activity in multiple sclerosis, particularly in the brain where it reveals subclinical inflammation. Established MRI markers include contrast-enhancing lesions and active T2 lesions. Recent promising markers like slowly expanding lesions and phase rim lesions are being explored for monitoring chronic inflammation, but require further validation for clinical use. Volumetric and quantitative MRI techniques are currently limited to clinical trials and are not yet recommended for routine clinical use. Additionally, MRI is crucial for detecting complications from disease-modifying treatments and for implementing MRI-based pharmacovigilance strategies, such as in patients treated with natalizumab.

Atypical demyelinating lesions (ADLs) can be idiopathic, occurring as isolated and self-limited events, or can appear in different stages of relapsing demyelinating diseases. Not infrequently, ADLs occur in inflammatory syndromes associated with exogenous or endogenous toxic factors, metabolic imbalance, or infectious agents. It is important to recognize imaging patterns that indicate an inflammatory/demyelinating substrate in central nervous system lesions and to investigate potential triggers or complicating factors that might be associated. The prognostic and treatment strategies of ADLs are influenced by the underlying etiopathogenesis.

Optic neuritis is a common feature in multiple sclerosis and in 2 other autoimmune demyelinating disorders such as aquaporin-4 IgG antibody-associated neuromyelitis optica spectrum disorder and myelin oligodendrocyte glycoprotein antibody-associated disease. Although serologic testing is critical for differentiating these different autoimmune-mediated disorders, MR imaging, which is the preferred imaging modality for assessing the optic nerve, can provide valuable information, suggesting a specific diagnosis and guiding the appropriate serologic testing.

Spinal cord MRI plays an important role in the diagnosis and prognosis of multiple sclerosis (MS) and related disorders. The ANATOMICAL, pathologic, imaging and prognostic consideriations for the spinal cord for MS and the most important other demyelinating disorders, neuromyelitis optica spectrum disorder and myelin oligodendrocyte glycoprotein-associated disease, are reviewed. Finally, differential diagnostic considerations of spinal cord MRI in MS and related disorders are discussed.

Multiple sclerosis (MS) is a neuroinflammatory and neurodegenerative disease of the central nervous system, commonly featuring disability and cognitive impairment. The pathologic hallmark of MS lies in demyelination and hence impaired structural and functional neuronal pathways. Recent studies have shown that MS shows extensive structural disconnection of key network hub areas like the thalamus, combined with a functional network reorganization that can mostly be related to poorer clinical functioning. As MS can, therefore, be considered a network disorder, this review outlines recent innovations in the field of network neuroscience in MS.

Concepts of multiple sclerosis (MS) biology continue to evolve, with observations such as \"progression independent of disease activity\" challenging traditional phenotypic categorization. Iron-sensitive, susceptibility-based imaging techniques are emerging as highly translatable MR imaging sequences that allow for visualization of at least 2 clinically useful biomarkers: the central vein sign and the paramagnetic rim lesion (PRL). Both biomarkers demonstrate high specificity in the discrimination of MS from other mimics and can be seen at 1.5 T and 3 T field strengths. Additionally, PRLs represent a subset of chronic active lesions engaged in \"smoldering\" compartmentalized inflammation behind an intact blood-brain barrier.
