Tracking changes in the serum biomarkers concentration along with monitoring of cerebral autoregulation, may play a role in early detection of patients at risk of DCI after aSAH. These results need to be validated in larger prospective cohorts.

Here, we presented a 33-year-old female patient with COVID-19, reporting acute-onset paranoid delusions symptoms, insomnia and irritability. Cranial MRI showed an hyperintense signal in the splenium of the corpus callosum with decreased apparent diffusion coefficient, which might possibly indicate the presence of cytotoxic edema related to the brain involvement of the infection. Following the completion of SARS-CoV-2 treatment, both cytotoxic edema and psychiatric symptoms resolved. In light of this report, we suggest that either heightened immune response and direct viral infection that SARS-CoV-2 may lead to such psychiatric manifestations and neuropsychiatric monitoring should be performed in patients with COVID-19. Prompt recognition of psychiatric consequences of COVID-19 may help clinicians provide guidance for differential diagnosis and manage them accordingly.The “Corona Virus Disease 2019 (COVID-19)”, caused by severe acute respiratory coronavirus 2 (SARS-CoV-2), progressed rapidly since its first outbreak, and quickly developed into a pandemic. Although COVID-19 mostly presents with respiratory symptoms, researchers have started reporting neurologic manifestations such as cerebrovascular diseases in patients, with COVID-19 as the pandemic has progressed. Herein, we report a case of 38-year-old female patient identified with a left common carotid artery dissection, with COVID-19. Clinicians must keep in mind that COVID-19 can cause vascular complications such as carotid artery dissections in the ensuing period, even after the acute phase, although there is currently a lack of sufficient evidence to identify any causal association between COVID-19 and arterial dissections.Determinants of tuberculosis (TB) syringomyelia, its management options and outcomes are still under investigation. The aim of this study is to present a case of TB syringomyelia with markedly improved symptoms status-post surgery and to understand the clinical characteristics and outcomes of 33 TB syringomyelia cases reported in the literature. Specifically, we examined the differences between patients who were managed medically and those who underwent surgical intervention. Inclusion criteria for the cases were (1) syringomyelia caused by TB infection rather than co-occurrence of these conditions, (2) management protocol described, and (3) post-treatment outcome described. The median age was 30 years (interquartile range (IQR) 23-40) with 55% males. The median time between TB onset to syringomyelia diagnosis was 2 years. Nineteen patients were surgically treated, 11 were medically treated, and 3 received no treatment. Twenty-one patients showed improvement in at least one prior symptom, but no patient experienced a full recovery. Those that underwent surgical intervention were more likely to have TB meningitis (95% vs. 64%, p less then 0.05) upon initial TB presentation and have a greater interval between TB onset and syringomyelia presentation (median of 2.6 vs. 0.33 years, ns). A greater proportion of the surgically managed patients experienced improvement in any symptom (74% vs. 45%, ns). Future case-controlled studies with larger sample sizes are required to validate and further understand the outcomes of surgically-managed TB syringomyelia.Arteriovenous malformations (AVMs) are a rare cause of cerebrovascular abnormality with incidence of about 1 in 100,000 people per year and point prevalence of about 0.2%. AVMs are associated with serious complications such as intracranial haemorrhage (2-4% a year, 16% and 29% at 10 and 20 years after diagnosis), seizures (10-30%), focal neurologic deficits, and headaches. The management options are surveillance, endovascular embolization, microsurgical excision and stereotactic radiosurgery (SRS). In SRS Stereotactically focused high energy beams of photons induce progressive thrombosis by fibro-intimal hyperplasia and subsequent luminal obliteration. These changes usually take one to three years known as “latency period”. Complications are reported in 8% of patients undergoing SRS, including radiographic parenchymal lesions, cranial nerve deficits, seizures, headaches, and cyst formation. Cyst formation is reported in about 1.2 % of patients undergoing SRS. While the exact mechanism of post SRS cyst formation is unclear, it is hypothesized that it might be due to damage to the blood brain barrier and increased vessel wall permeability. Delayed cyst formation is reported with latency period between 3 and 10 years after radiotherapy for treatment of cerebrovascular AVMs. However, cystic formation with longer latency periods (in one case upto 17 years) after radiotherapy for other causes such as nasopharyngeal cancers have been reported. Here we report a case of delayed cyst formation after SRS for cerebrovascular AVM with latency period of 20 years.Cervical Dystonia (CD) and Parkinson’s disease, particularly tremor-dominant motor phenotype (TD-PD), showed a selective deficit of time-based prospective memory (TBPM). The two movement disorders are mainly characterized by dysfunctions of basal-ganglia and prefrontal cortex but it is reported that cerebellum also plays a key role in their pathogenesis. These cerebral structures are specifically involved in TBPM rather than in event-based PM (EBPM), but until now no study directly compared these two components of PM between CD and TD-PD patients. Therefore, the present study aimed at investigating if differences in PM functioning between CD and TD-PD patients might exist and if the type of movement disorder moderated the relationship between deficit of PM and deficit of executive functions and retrospective memory. Thirty TD-PD, 27CD patients and 29 healthy subjects (HCs), matched for demographic features, underwent neuropsychological tests for PM, executive functions, retrospective memory and self-rated questionnaires.
