{"title":"The challenge of exploring neuropsychiatric and cognitive symptoms after spontaneous intracerebral hemorrhage","authors":"Giuseppe Scopelliti, Charlotte Cordonnier, Leonardo Pantoni","doi":"10.1111/ene.16585","DOIUrl":"10.1111/ene.16585","url":null,"abstract":"<p>Spontaneous intracerebral hemorrhage (ICH) is an extremely dangerous condition, with overall greater social-economic burden than ischemic stroke despite lower incidence. Approximately half of patients with acute ICH do not survive beyond the first year, and those who do often face significant, lasting disability [<span>1</span>]. Qiuyi Jiang et al. investigated one of the more subtle long-term effects of ICH, the affective and cognitive symptoms that have been often overlooked by stroke neurologists, but are an especially pressing burden for patients and their caregivers [<span>2, 3</span>]. This study, conducted in China, included nearly 1600 patients, marking the largest cohort on this topic to date. However, the majority of participants had deep ICH (85%) and were relatively young (median age 57 years), limiting the generalizability of the findings to older populations with lobar ICH.</p><p>Although the study explicitly focused on “small” ICHs (median volume of 10 mL), it should be noted that the majority of previous studies on long-term cognitive and neuropsychiatric outcomes of ICH have also predominantly included patients with smaller hematoma volumes [<span>4, 5</span>]. This is mainly because larger hemorrhages are associated with poor short-term survival, or patients are less likely to be able to attend outpatient clinic for long term follow-up. Similar considerations can be made regarding studies on the long-term cognitive consequences of ischemic stroke, in which patients with more severe events and language impairment are often excluded, resulting in an unavoidable bias in evaluating long-term trajectories [<span>6</span>]. Nevertheless, we might hypothesize that those patients suffering from lower levels of disability after the index event are probably the ones who are going to benefit the most from a long-term stroke neuropsychiatric and cognitive follow-up.</p><p>Given that most studies have predominantly focused on small ICHs, our understanding of the cognitive and neuropsychiatric consequences of ICH survivors so far may reflect more the influence of the underlying cerebral small vessel disease (e.g., arteriolosclerosis and cerebral amyloid angiopathy) rather than the direct impact of the initial ICH event. Although this study did not assess MRI features of cerebral small vessel disease, the authors found that potentially modifiable factors related to ICH at baseline (e.g., blood pressure levels, length of hospitalization, and anteroposterior diameter of the index ICH) could influence long-term cognitive and affective outcomes. This finding underscores the importance of consistently including cognitive and affective measures as outcome variables in clinical trials of acute phase interventions.</p><p>Another important catch on the current topic is the complex presentation of affective symptoms following an ICH, and, more broadly, in patients with cerebrovascular diseases.

They compared 665 patients with progressive multiple sclerosis (PMS) of which 74 were primary progressive MS (PPMS) defined as PMS from diagnosis and 591 with secondary progressive MS (SPMS) defined as PMS after an initial relapsing–remitting course. As controls they used 647 patients with RRMS defined as a relapsing–remitting course with stable neurological disability between relapses [<span>1</span>].</p><p>There are 16 disease modifying therapies (DMTs) approved by the Food and Drug Administration for RRMS. The effectiveness of DMTs for PMS is questionable or at best less clear. Multiple studies have demonstrated superiority of HSCT for RRMS including a large meta-analysis of 4831 patients [<span>2</span>] and a phase III randomized trial [<span>3</span>]. Because an effective therapy is needed for PMS, Braun et al. summarized the published outcome of HSCT for PMS. They found highly variable results in PMS patients in terms of achieving progression-free survival and no evidence of disease activity (NEDA-3), suggesting that HSCT does not halt progression in this patient cohort but may provide clinical benefit in selected patients.</p><p>RRMS is a dynamic and repetitive immune mediated breakdown in the blood–brain barrier, extravasation of immune cells, and macrophage stripping of myelin followed healing of the blood–brain barrier, remyelination and repair [<span>4</span>]. Neuronal damage starts during RRMS and becomes the predominate pathophysiology during SPMS [<span>5</span>]. PPMS is predominately neuronal degenerative from onset [<span>6</span>]. For this reason, immune based therapies including all DMTs and autologous HSCT are most effective in RRMS but of limited value for PMS (PPMS or SPMS) [<span>6</span>]. During the transition from predominately inflammatory RRMS into late SPMS, patients transition through a stage of SPMS with residual smoldering inflammation [<span>7</span>]. It is during this stage that immune based therapies such as HSCT are still of benefit, albeit to a lesser amount. On this background, recent guidelines and recommendations from the European Group for Blood and Marrow Transplantation (EBMT) Autoimmune Diseases Working Party (ADWP) and the Joint Accreditation Committee of EBMT and the International Society for Cellular Therapy (ISCT) (JACIE) suggest HSCT as standard indication in patients with active relapsing–remitting MS failing DMTs, and a clinical option in patients with progressive MS with active inflammatory component, but generally not in patients with progressive MS without active inflammatory component [<span>8</span>].</p><p>Identifying subsets of","PeriodicalId":11954,"journal":{"name":"European Journal of Neurology","volume":"32 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ene.16565","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142846016","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}
