Introduction: Sarcoidosis affects the central nervous system more frequently than it used to be believed. While the cranial nerves are most frequently affected, neurosarcoidosis can involve other nervous system tissues as well. Treatment of Neurosarcoidosis: Although a lot of drugs have proved useful in treating neurosarcoidosis, corticosteroids are still the gold standard in treatment of these patients. Therapeutic protocols differ regarding the dose of these drugs. Symptomatic neurosarcoidosis should always be treated with pulse corticosteroid therapy. People with diabetes, high blood pressure, osteoporosis and tuberculosis should be carefully monitored, as they are prone to complications associated with treatment with corticosteroids. In cases when treatment with corticosteroids does not show the desired results or therapy is discontinued due to the development of side effects, there are other pharmacologic options, such as methotrexate, mycophenolate mofetil, cyclophosphamide, chloroquine, azathioprine, thalidomide, and infliximab. It should be noted that the treatment response to the above mentioned regimens, except for infliximab, is relatively slow compared to corticosteroids; therefore, corticosteroids should be taken into account in all states and particularly in the acute phase of the disease. Conclusion: It is the existence of different forms of the disease, lack of local diagnostic criteria and different and non standardized therapy that makes the treatment of this disease difficult. Despite advances in pharmacotherapy and radiological diagnosis, it is necessary to develop better diagnostic strategies in order to set the optimal therapeutic approach.

An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma.The aim of this study was to evaluate the correlation between ocular pulse amplitude (OPA), measured by Dynamic contour tonometer (DCT) and colour Doppler imaging (CDI) of the arteric retrobulbar vessels.Twenty patients older than 50 years were examined, and divided into two equal groups. The first group comprised of patients with normal tension glaucoma treated with topical antiglaucomatous therapy, and the second group included patients with ocular hypertension and glaucoma suspicious without any antiglaucomatous therapy. Ocular pulse amplitude (OPA) was measured with DCT. CDI was also performed. We measured haemodynamic parameters of the internal carotid artery (ICA), ophthalmic artery (OA), central retinal artery (CRA), and posterior ciliary arteries (PCA). Peak systolic (PSV), end-diastolic (EDV) velocities were measured, and resistance index (RI) and pulsatility index (PI) were calculated.Correlation with OPA showed indirect servitude in the RI of the ICA, RI and PI of the CRA, in the first group; and in the PSV and EDV of the ICA, in the RI and PI of the OA, EDV and RI of the CRA, and RI of the PCA, in the second groupIncrease of OPA was mostly followed by the increase of the parameters (PSV, EDV, RI, and PI) of the arteric retrobulbar vessels in the first group; in the second group, increase of OPA was in almost 50% of parameters followed by their decrease.

Phenotypic and Genetic Heterogeneity of Adult Patients with Hereditary Spastic Paraplegia from Serbia

Cells (2022)

Stojan Perić Vladana Marković Ayşe Candayan Els De Vriendt Nikola Momčilović

Hereditary spastic paraplegia (HSP) is among the most genetically diverse of all monogenic diseases. The aim was to analyze the genetic causes of HSP among adult Serbian patients. The study comprised 74 patients from 65 families clinically diagnosed with HSP during a nine-year prospective period. A panel of thirteen genes was analyzed: L1CAM (SPG1), PLP1 (SPG2), ATL1 (SPG3A), SPAST (SPG4), CYP7B1 (SPG5A), SPG7 (SPG7), KIF5A (SPG10), SPG11 (SPG11), ZYFVE26 (SPG15), REEP1 (SPG31), ATP13A2 (SPG78), DYNC1H1, and BICD2 using a next generation sequencing-based technique. A copy number variation (CNV) test for SPAST, SPG7, and SPG11 was also performed. Twenty-three patients from 19 families (29.2%) had conclusive genetic findings, including 75.0% of families with autosomal dominant and 25.0% with autosomal recessive inheritance, and 15.7% of sporadic cases. Twelve families had mutations in the SPAST gene, usually with a pure HSP phenotype. Three sporadic patients had conclusive findings in the SPG11 gene. Two unrelated patients carried a homozygous pathogenic mutation c.233T>A (p.L78*) in SPG7 that is a founder Roma mutation. One patient had a heterozygous de novo variant in the KIF5A gene, and one had a compound heterozygous mutation in the ZYFVE26 gene. The combined genetic yield of our gene panel and CNV analysis for HSP was around 30%. Our findings broaden the knowledge on the genetic epidemiology of HSP, with implications for molecular diagnostics in this region.

Transcranial Sonography Characteristics of Cerebellar Neurodegenerative Ataxias

Brain Sciences (2024)

Olivera Tamaš Milija Mijajlović Tamara Švabić Milutin Kostić Gorica Marić

Cerebellar neurodegenerative ataxias are a group of disorders affecting the cerebellum and its pathways with different neurological structures. Transcranial sonography (TCS) has been used for the evaluation of brain parenchymal structures in various diseases because of its fast and safe utilization, especially in neuropsychiatric and neurodegenerative diseases. The aim of our study was to investigate TCS characteristics of patients with neurodegenerative cerebellar ataxias. In our study, we included 74 patients with cerebellar degenerative ataxia; 36.5% had autosomal dominant onset, while 33.8% had sporadic onset. Standardized ultrasonographic planes were used for the identification of brain structures of interest. The SARA, INAS, neuropsychological and psychiatric scales were used for the further clinical evaluation of our study participants. The brainstem raphe was discontinued in 33.8% of the patients. The substantia nigra (SN) hyperechogenicity was identified in 79.7%. The third and fourth ventricle enlargement had 79.7% and 45.9% of patients, respectively. A positive and statistically significant correlation was found between SN hyperechogenicity with dystonia (p < 0.01), rigidity and dyskinesia (p < 0.05). The higher SARA total score is statistically significantly correlated with the larger diameter of the III (r = 0.373; p = 0.001) and IV ventricles (r = 0.324; p = 0.005). In such patients, the echogenicity of substantia nigra has been linked to extrapyramidal signs, and raphe discontinuity to depression. Furthermore, ataxia and its clinical subtypes have positively correlated with the IV ventricle diameter, indicating brain atrophy and brain mass reduction.

Delivery of acute ischaemic stroke treatments in the European region in 2019 and 2020

European Stroke Journal (2023)

Diana Aguiar de Sousa Arlene Wilkie Bo Norrving Chris Macey Claudio L. Bassetti

We assessed best available data on access and delivery of acute stroke unit (SU) care, intravenous thrombolysis (IVT) and endovascular treatment (EVT) in the European region in 2019 and 2020.We compared national data per number of inhabitants and per 100 annual incident first-ever ischaemic strokes (AIIS) in 46 countries. Population estimates and ischaemic stroke incidence were based on United Nations data and the Global Burden of Disease Report 2019, respectively.The estimated mean number of acute SUs in 2019 was 3.68 (95% CI: 2.90-4.45) per one million inhabitants (MIH) with 7/44 countries having less than one SU per one MIH. The estimated mean annual number of IVTs was 21.03 (95% CI: 15.63-26.43) per 100,000 and 17.14% (95% CI: 12.98-21.30) of the AIIS in 2019, with highest country rates at 79.19 and 52.66%, respectively, and 15 countries delivering less than 10 IVT per 100,000. The estimated mean annual number of EVTs in 2019 was 7.87 (95% CI: 5.96-9.77) per 100,000 and 6.91% (95% CI: 5.15-8.67) of AIIS, with 11 countries delivering less than 1.5 EVT per 100,000. Rates of SUs, IVT and EVT were stable in 2020. There was an increase in mean rates of SUs, IVT and EVT compared to similar data from 2016.Although there was an increase in reperfusion treatment rates in many countries between 2016 and 2019, this was halted in 2020. There are persistent major inequalities in acute stroke treatment in the European region. Tailored strategies directed to the most vulnerable regions should be prioritised.

Vascular depression consensus report – a critical update

BMC Medicine (2016)

Howard Aizenstein Andrius Baskys Maura Boldrini Meryl A. Butters Breno S. Diniz

Vascular depression is regarded as a subtype of late-life depression characterized by a distinct clinical presentation and an association with cerebrovascular damage. Although the term is commonly used in research settings, widely accepted diagnostic criteria are lacking and vascular depression is absent from formal psychiatric manuals such as the Diagnostic and Statistical Manual of Mental Disorders, 5th edition - a fact that limits its use in clinical settings. Magnetic resonance imaging (MRI) techniques, showing a variety of cerebrovascular lesions, including extensive white matter hyperintensities, subcortical microvascular lesions, lacunes, and microinfarcts, in patients with late life depression, led to the introduction of the term "MRI-defined vascular depression".This diagnosis, based on clinical and MRI findings, suggests that vascular lesions lead to depression by disruption of frontal-subcortical-limbic networks involved in mood regulation. However, despite multiple MRI approaches to shed light on the spatiotemporal structural changes associated with late life depression, the causal relationship between brain changes, related lesions, and late life depression remains controversial. While postmortem studies of elderly persons who died from suicide revealed lacunes, small vessel, and Alzheimer-related pathologies, recent autopsy data challenged the role of these lesions in the pathogenesis of vascular depression. Current data propose that the vascular depression connotation should be reserved for depressed older patients with vascular pathology and evident cerebral involvement. Based on current knowledge, the correlations between intra vitam neuroimaging findings and their postmortem validity as well as the role of peripheral markers of vascular disease in late life depression are discussed.The multifold pathogenesis of vascular depression as a possible subtype of late life depression needs further elucidation. There is a need for correlative clinical, intra vitam structural and functional MRI as well as postmortem MRI and neuropathological studies in order to confirm the relationship between clinical symptomatology and changes in specific brain regions related to depression. To elucidate the causal relationship between regional vascular brain changes and vascular depression, animal models could be helpful. Current treatment options include a combination of vasoactive drugs and antidepressants, but the outcomes are still unsatisfying.
