Risk factors and mechanisms of stroke in young adults: The FUTURE study
Incidence of ischemic stroke and transient ischemic attack in young adults is rising. However, etiology remains unknown in 30–40% of these patients when current classification systems designed for the elderly are used. Our aim was to identify risk factors according to a pediatric approach, which might lead to both better identification of risk factors and provide a stepping stone for the understanding of disease mechanism, particularly in patients currently classified as “unknown etiology”. Risk factors of 656 young stroke patients (aged 18–50) of the FUTURE study were categorized according to the “International Pediatric Stroke Study” (IPSS), with stratification on gender, age and stroke of “unknown etiology”. Categorization of risk factors into ≥1 IPSS category was possible in 94% of young stroke patients. Chronic systemic conditions were more present in patients aged <35 compared to patients ≥35 (32.6% vs. 15.6%, p < 0.05). Among 226 patients classified as “stroke of unknown etiology” using TOAST, we found risk factors in 199 patients (88%) with the IPSS approach. We identified multiple risk factors linked to other mechanisms of stroke in the young than in the elderly. This can be a valuable starting point to develop an etiologic classification system specifically designed for young stroke patients.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: de Leeuw is supported by a clinical established investigator grant of the Dutch Heart Foundation (grant no. 2014 T060), and by a VIDI innovational grant from The Netherlands Organisation for Health Research and Development ZonMw (grant no. 016-126-351) and has also received research support from the “Dutch Epilepsy Fund” (grant no. 2010-18); Loes Rutten-Jacobs (LR-J) is supported by a British Heart Foundation Immediate Research Fellowship (FS/15/61/31626) (www.bhf.org.uk)
Risk factors and causes of ischemic stroke in 1322 young adults
Background:Identification of risk factors and causes of stroke is key to optimize treatment and prevent recurrence. Up to one-third of young patients with stroke have a cryptogenic stroke according to current classification systems (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] and atherosclerosis, small vessel disease, cardiac pathology, other causes, dissection [ASCOD]). The aim was to identify risk factors and leads for (new) causes of cryptogenic ischemic stroke in young adults, using the pediatric classification system from the IPSS study (International Pediatric Stroke Study).Methods:This is a multicenter prospective cohort study conducted in 17 hospitals in the Netherlands, consisting of 1322 patients aged 18 to 49 years with first-ever, imaging confirmed, ischemic stroke between 2013 and 2021. The main outcome was distribution of risk factors according to IPSS classification in patients with cryptogenic and noncryptogenic stroke according to the TOAST and ASCOD classification.Results:The median age was 44.2 years, and 697 (52.7%) were men. Of these 1322 patients, 333 (25.2%) had a cryptogenic stroke according to the TOAST classification. Additional classification using the ASCOD criteria reduced the number patients with cryptogenic stroke from 333 to 260 (19.7%). When risk factors according to the IPSS were taken into account, the number of patients with no potential cause or risk factor for stroke reduced to 10 (0.8%).Conclusions:Among young adults aged 18 to 49 years with a cryptogenic ischemic stroke according to the TOAST classification, risk factors for stroke are highly prevalent. Using a pediatric classification system provides new leads for the possible causes in cryptogenic stroke, and could potentially lead to more tailored treatment for young individuals with stroke.Neurological Motor Disorder
Trigger factors for stroke in young adults: a case-crossover study
Background and ObjectivesCauses of stroke in young adults differ from those in the elderly individuals, and in a larger percentage,no cause can be determined. To gain more insight into the etiology of (cryptogenic) stroke in theyoung population, we investigated whether trigger factors, such as short-lasting exposure to toxins orinfection, may play a role.MethodsPatients aged 18–49 years with a first-ever ischemic stroke or intracerebral hemorrhage (ICH) in 17participating centers in the Netherlands completed a questionnaire about exposure to 9 potentialtrigger factors in hazard periods and on a regular yearly basis. A case-crossover design was used toassess relative risks (RRs) with 95% confidence intervals (95% CIs) by the Mantel-Haenszel case-crossover method, for any stroke (ischemic stroke and ICH combined) and for different etiologicsubgroups of ischemic stroke.ResultsOne thousand one hundred forty-six patients completed the questionnaire (1,043 patients withan ischemic stroke and 103 with an ICH, median age 44.0 years, 52.6% men). For any stroke, anincreased risk emerged within 1 hour of cola consumption (RR 2.0, 95% CI 1.5–2.8) and vigorousphysical exercise (RR 2.6, 95% CI 2.2–3.0), within 2 hours after sexual activity (RR 2.4, 95% CI1.6–3.5), within 4 hours after illicit drug use (RR 2.8, 95% CI 1.7–4.9), and within 24 hours afterfever or flu-like disease (RR 14.1, 95% CI 10.5–31.2; RR 13.9, 95% CI 8.9–21.9). Four triggerfactors increased the risk of other determined and cryptogenic ischemic stroke, 3 that of car-dioembolic stroke, 2 that of large vessel atherosclerosis and likely atherothrombotic strokecombined and stroke with multiple causes, and none that of stroke due to small vessel disease.DiscussionWe identified cola consumption, vigorous physical exercise, sexual activity, illicit drug use, fever, andflu-like disease as potential trigger factors for stroke in the young population and found differencesin the type and number of trigger factors associated with different etiologic subgroups of ischemicstroke. These findings might help in better understanding the pathophysiologic mechanisms of(cryptogenic) stroke in the young population.Paroxysmal Cerebral Disorder

207224.pdf (publisher's version ) (Open Access)OBJECTIVE: To investigate incidence of stroke and its subtypes in young adults, according to sex and age, and to study trends over time. METHODS: We established a nationwide cohort through linkage of national registries (hospital discharge, cause of death, and population register) with patients aged 18-50 years and those >/=50 years with first-ever ischemic stroke, intracerebral hemorrhage, or unspecified stroke, using ICD-9/ICD-10 codes between 1998 and 2010 in the Netherlands. Outcomes were yearly incidence of stroke stratified by age, sex, and stroke subtype, its changes over time, and comparison of incidence in patients 18-50 years to patients >/=50 years. RESULTS: We identified 15,257 patients (53% women; mean age 41.8 years). Incidence increased exponentially with age (R (2) = 0.99) and was higher for women than men, most prominently in the youngest patients (18-44 years). The relative proportion of ischemic stroke increased with age (18-24 years: 38.3%; 44-49 years: 56.5%), whereas the relative proportion of intracerebral hemorrhage decreased (18-24 years: 34.0%; 44-49 years: 18.3%). Incidence of any stroke in young adults increased (1998: 14.0/100,000 person-years: 2010: 17.2; +23%; p /=50 years (329.1%-292.2%; -11%; p = 0.009). CONCLUSIONS: Incidence of any stroke in the young increases with age in patients over 35, is higher in women than men aged 18-44 years, and has increased by 23% in one decade, through an increase in ischemic stroke. Incidence of intracerebral hemorrhage is comparable for women and men and remained stable over time
Neurorehabilitation for Parkinson's disease: Future perspectives for behavioural adaptation
Parkinson's disease is a common neurodegenerative disorder, resulting in both motor and non-motor symptoms that significantly reduce quality of life. Treatment consists of both pharmaceutical and non-pharmaceutical treatment approaches. Neurorehabilitation is an important non-pharmaceutical treatment approach, and a prime component of this is formed by the training of behavioural adaptations that can assist patients to cope better with their motor and non-motor symptoms. Optimal delivery of neurorehabilitation requires a tailor-made, personalized approach. In this review we discuss the great potential for growth in the field of neurorehabilitation. Specifically, we will focus on four relatively new developments: visual rehabilitation (because Parkinson patients are very dependent on optimal vision); cueing delivered by wearable devices (allowing for objective, continuous, and quantitative detection of mobility problems, such that cueing can be delivered effectively in an on-demand manner - i.e., with external cues being delivered only at a time when they are needed most); exergaming (to promote compliance with exercise programs); and telemedicine (allowing for delivery of expert rehabilitation advice to the patient's own home). Evidence in these new fields is growing, based on good clinical trials, fuelling hope that state-of-the-art neurorehabilitation can make a real impact on improving the quality of life of patients affected by Parkinson's disease

Ischaemic stroke in young adults: a global perspective
Contains fulltext :
220673.pdf (Publisher’s version ) (Closed access)Ischaemic stroke at young age is an increasing problem in both developing and developed countries due to rising incidence, high morbidity and mortality and long-term psychological, physical and social consequences. Compared with stroke in older adults, stroke in young adults is more heterogeneous due to the wide variety of possible underlying risk factors and aetiologies. In this review, we will provide an overview of the global variation in the epidemiology of stroke in young adults, with special attention to differences in geography, ethnicity/race and sex, as well as traditional and novel risk factors for early-onset ischaemic stroke, such as air pollution. Understanding global differences is an important prerequisite for better region-specific prevention and treatment of this devastating condition
