Although diagnosis of CAA was made only with postmortem neuropathological examination a few decades ago, diagnosing CAA without pathological proof is now allowed in living patients. This review focuses on recently identified biomarkers of CAA and current diagnostic criteria.Recent findings: Over the past few years, clinicians and researchers have shown increased interest for CAA, and important advances have been made. Thanks to recent insights into mechanisms involved in CAA and advances in structural and functional neuroimaging, PET amyloid tracers, cerebrospinal fluid and plasma biomarkers analysis, a growing number of biomarkers of CAA have been identified. Imaging-based diagnostic criteria including emerging biomarkers have been recently developed or updated, enabling accurate and earlier diagnosis of CAA in living patients.Summary: Recent advances in neuroimaging allow diagnosing CAA in the absence of pathological examination. Current imaging-based criteria have high diagnostic performance in patients presenting with ICH, but is more limited in other clinical context such as cognitively impaired patients or asymptomatic individuals. Further research is still needed to improve diagnostic accuracy.","PeriodicalId":11059,"journal":{"name":"Current Opinion in Neurology","volume":" ","pages":"19-25"},"PeriodicalIF":4.8,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138458508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multimodal cerebral imaging combined with behavioural testing of spatial orientation and navigation performance as well as strategy in the last years helped to decipher vestibular-cognitive interactions also in humans.Summary: This review will update the current knowledge on the anatomical and cellular basis of vestibular contributions to spatial orientation and navigation from a translational perspective (animal and human studies), delineate the behavioural and functional consequences of different vestibular pathologies on these cognitive domains, and will lastly speculate on a potential role of vestibular dysfunction for cognitive aging and impeding cognitive impairment in analogy to the well known effects of hearing loss.","PeriodicalId":11059,"journal":{"name":"Current Opinion in Neurology","volume":" ","pages":"52-58"},"PeriodicalIF":4.8,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10779452/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138444265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, a plethora of paracrine, mostly tumor-promoting neuro-cancer interactions are reported, and a neuro-immuno-cancer axis emerges. Cancer cell-intrinsic neural properties, and cancer (therapy) effects on the nervous system that cause morbidity in patients and can establish harmful feedback loops receive increasing attention. Despite the relative novelty of these findings, therapies that inhibit key mechanisms of this neuro-cancer crosstalk are developed, and already tested in clinical trials, largely by repurposing of approved drugs.Summary: Neuro-cancer interactions are manyfold, have multiple clinical implications, and can lead to novel neuroscience-instructed cancer therapies and improved therapies of neurological dysfunctions and cancer pain.

Weight loss remains the most effective management strategy, but innovative treatments and randomized control trials (RCTs) remain few. This paper will review recent IIH research.Recent findings: Pregnancy-related complications, but not losses, are increased in IIH, while symptom severity is not affected. Weight loss of 24% results in normalization of intracranial pressure (ICP) and improvement in papilledema. Prolonged periods of papilledema result in delayed thinning of the ganglion cell layer. Less-invasive telemetry has improved understanding of the positional effects on ICP with rises seen in the supine and lateral positions. Exenatide, a GLP-1 agonist, may reduce ICP and improve symptoms. Venous sinus stenting is increasingly popular but its benefits over CSF diversion remain unclear.Summary: Early involvement of obstetric care is recommended with pregnancy in IIH. Early intervention is required to avoid chronic papilledema that confers worse visual outcomes. Positional changes may affect ICP readings. The use of novel ICP telemetric devices has significant potential in future disease monitoring. The dual benefits of weight loss and ICP reduction with exenatide have significant potential in IIH management.

There is a higher prevalence of headache in individuals with long COVID who contracted the Delta variant than in those who were infected with the Wuhan or Alpha variants. Headaches related to COVID-19 infection are commoner and may be more intense in women.There are indications that presence of headache might indicate a more benign COVID-19 infection and a better chance of survival. However, the impact of COVID-19 related headache could be substantial leading to poor quality of life in individuals affected. Headache that changes in its nature in terms of frequency and severity should be investigated to exclude cerebrovascular complications.

The two major molecular alterations behind epileptogenicity are the rat sarcoma virus (RAS)/mitogen-activated protein kinase / extracellular signal-regulated kinase (MAPK/ERK) and phosphatidylinositol-3-kinase / protein kinase B / mammalian target of rapamycin (P13K/AKT/mTOR) pathways. The BRAFv600E mutation has been shown in experimental models to contribute to epileptogenicity, and its inhibition is effective in controlling both seizures and tumor growth. Regarding circumscribed astrocytic gliomas, either BRAFv600E mutation or mTOR hyperactivation represent targets of treatment. The mechanisms of epileptogenicity of diffuse lower-grade gliomas are different: in addition to enhanced glutamatergic mechanisms, the isocitrate dehydrogenase (IDH) 1/2 mutations and their product D2-hydroxyglutarate (D2HG), which is structurally similar to glutamate, exerts excitatory effects on neurons also dependent on the presence of astrocytes. In preclinical models IDH1/2 inhibitors seem to impact both tumor growth and seizures. Conversely, the molecular factors behind the epileptogenicity of glioblastoma are unknown.Summary: This review summarizes the current state of molecular knowledge on epileptogenicity in gliomas and highlights the relationships between epileptogenicity and tumor growth.","PeriodicalId":11059,"journal":{"name":"Current Opinion in Neurology","volume":" ","pages":"557-563"},"PeriodicalIF":4.8,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49675441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
