Background To differentiate primary headache associated with sexual activity from other devastating secondary causes. Methods In this prospective cohort, we recruited consecutive patients with at least 2 attacks of headache associated with sexual activity from the headache clinics or emergency department of a national medical center from 2005 to 2020. Detailed interview, neurological examination, and serial thorough neuroimaging including brain magnetic resonance imaging and magnetic resonance angiography scans were performed on registration and during follow-ups. Patients were categorized into four groups, i.e. primary headache associated with sexual activity, reversible cerebral vasoconstriction syndrome, probable reversible cerebral vasoconstriction syndrome, and other secondary headache associated with sexual activity through a composite clinic-radiological diagnostic algorithm. We compared the clinical profiles among these groups, including sex, age of onset, duration, quality, and clinical course (“chronic” indicates disease course ≥ 1 year). In addition, we also calculated the score of the reversible cerebral vasoconstriction syndrome2, a scale developed to differentiate reversible cerebral vasoconstriction syndrome from other intracranial vascular disorders. Results Overall, 245 patients with headache associated with sexual activity were enrolled. Our clinic-radiologic composite algorithm diagnosed and classified all patients into four groups, including 38 (15.5%) with primary headache associated with sexual activity, 174 (71.0%) with reversible cerebral vasoconstriction syndrome, 26 (10.6%) with probable reversible cerebral vasoconstriction syndrome, and 7 (2.9%) with other secondary causes (aneurysmal subarachnoid hemorrhage (n = 4), right internal carotid artery dissection (n = 1), Moyamoya disease (n = 1), and meningioma with hemorrhage (n = 1)). These four groups shared similar clinical profiles, except 26% of the patients with primary headache associated with sexual activity had a 3 times greater chance of running a chronic course (≥ 1 year) than patients with reversible cerebral vasoconstriction syndrome. Of note, the reversible cerebral vasoconstriction syndrome2 score could not differentiate reversible cerebral vasoconstriction syndrome from other groups. Conclusion Our composite clinic-radiological diagnostic algorithm successfully classified repeated headaches associated with sexual activity, which were predominantly secondary and related to vascular disorders, and predicted the prognosis. Primary headache associated with sexual activity and reversible cerebral vasoconstriction syndrome presented with repeated attacks of headache associated with sexual activity may be of the same disease spectrum.

BACKGROUND Young stroke incidence has increased worldwide with lifestyle changes. Etiology and risk factors for both ischemic and hemorrhagic stroke in young Asians remain underexplored. METHODS We retrospectively reviewed consecutive acute stroke patients aged 16-45 years admitted to the Taipei Veterans General Hospital between 2009 and 2019 to analyze etiologic subtypes, risk factors, and serial modified Rankin Scale scores for 1 year and compare the age groups of 16-30 and 31-45 years. RESULTS Among 670 young Taiwanese patients (mean age at onset 37.5 ± 7.0 years; male 65.1%), there were 366 nontraumatic spontaneous hemorrhagic stroke (including 259 intracerebral hemorrhage [ICH] and 107 subarachnoid hemorrhage, SAH), 292 ischemic stroke and 12 cerebral venous thromboses. Notably, ICH was more prevalent in patients aged 16-30 than in those aged 31-45 (54.8% vs 36.8%). Specifically, structural vasculopathy (e.g., arteriovenous malformation, cavernoma) was the most common etiologic subtype in patients aged 16-30 (p < 0.001), whereas hypertensive ICH was the most common subtype in patients aged 31-45 (p < 0.001). On the other hand, the top ischemic subtype for both age groups was other determined diseases (e.g., arterial dissection, autoimmune diseases, moyamoya disease, etc.) rather than large artery atherosclerosis. Hyperlipidemia, diabetes, and cigarette smoking were more common risk factors for infarction than ICH. Familial stroke patients whose first- or second-degree relatives had a stroke by age 80 (n = 104, 15.5%) had more infarctions than those without a familial stroke history. In multivariate analyses, initial stroke severity, and infarction type were important predictors of favorable outcomes after 3 months. At the 1-year follow-up, patients with ICH and SAH had worse functional outcomes and survival rates than those with infarction. CONCLUSION An aggressive approach to elucidate the etiology of stroke is indicated because structural vasculopathy-induced ICH and other determined infarction are distinctively prevalent in young adults, particularly those aged 16-30.

Introduction Acute withdrawal of antiepileptic drugs (AEDs) is a safe and effective approach to provoking seizures in order to complete video-electroencephalogram (V-EEG) studies in a timely manner. Previous studies have focused only on withdrawal from conventional AEDs, and the effects of withdrawal from new-generation AEDs have not been extensively studied. Materials and Methods This study examined adult patients with drug-resistant epilepsy admitted to an epilepsy monitoring unit between 2015 and 2018. Patients were classified according to whether they received conventional AEDs (Con; n = 13) or new-generation AEDs (N-Gen; n = 26). We then compared the effects of withdrawing these two types of AEDs over a period of one week in terms of efficacy (time to complete V-EEG monitoring) and safety, including the incidence of cluster seizures (CS), focal to bilateral tonic-clonic seizures (FBTCS) and status epilepticus (SE). Results In both groups, approximately one week was required to complete V-EEG analysis: N-Gen group (5.6 days) and Con group (6.3 days). No differences were observed between the two groups in terms of the median number of seizures, the onset of the 1st seizure, the distribution of CS, FBTCS, or SE. Following acute withdrawal of medication, a high percentage of patients with a history of CS or FBTCS, respectively, presented CS or FBTCS. Conclusions We did not observe significant differences between patients taking new-generation AEDs and those taking conventional AEDs following withdrawal during V-EEG recording. In the current study, we employed a standard protocol for the rapid withdrawal of AEDs (daily dose reduction of 50%), which was sufficient for 80% of patients to complete V-EEG monitoring within one week.

Background Early-onset adult stroke has not been fully characterized in Asians. Objectives We investigated the etiologic subtypes, risk factors and 1-year outcomes of early-onset stroke (16 – 55 years of age) in a Taiwanese cohort. Methods We retrospectively reviewed consecutive patients with acute stroke admitted to the Taipei Veterans General Hospital in Taiwan between 2009 and 2017. Patients were classified by age of onset (≤ or > 55) and etiologic subtypes and regularly followed for 1 year. Results Among all stroke patients (n=8155), 17.6% (n=1310) were early-onset, who had slightly more spontaneous hemorrhagic stroke (50.8%) than ischemic stroke (49.2%). The most common etiologic subtypes of hemorrhagic stroke were hypertensive intracerebral hemorrhage (ICH), subarachnoid hemorrhage and undetermined ICH. The most common subtypes of infarction were large artery atherosclerosis, other determined diseases (52.5% arterial dissection) and embolic stroke of undetermined source. Smoking, alcohol overdrink, obesity, ischemic heart disease and family history of stroke were more in the early-onset than the elderly patients. The early-onset patients with familial stroke (n=87, 6.6%) were more males and more commonly had infarction than those without familial stroke. Monogenic diseases accounted for 5.7% of young familial stroke. At 1-year follow-up, the early-onset patients with infarction displayed greater functional improvements but more stroke recurrence than those with ICH. Conclusions Hypertensive hemorrhagic stroke and large artery atherosclerosis or dissection occlusion are characteristically common etiologies of young stroke in Taiwan. Early-onset infarction had higher recurrence yet better 1-year outcomes than early-onset ICH. Patients with familial versus non-familial aggregation had more ischemic infarction and monogenic diseases.

An improvement in quality of life (QoL) over time after epilepsy surgery has been demonstrated in people with epilepsy; however, social functioning has been less investigated. We conducted this study to examine whether postsurgical improvement is parallel between QoL and social functioning in patients with epilepsy.We retrospectively reviewed patients who underwent epilepsy surgery. All participants completed a comprehensive neuropsychological assessment, the Quality of Life in Epilepsy Inventory (QOLIE-89) questionnaire, and the Social and Occupational Functioning Scale for Epilepsy (SOFSE) before surgery and at 3 months, 6 months, and 1 year after surgery. Demographic and epilepsy-related information was also collected. Generalized estimating equations with identity links were used to model the QOLIE-89 and SOFSE over time and possible associated factors. A p 0.05 was considered statistically significant.A total of 76 patients, including 36 males and 43 females aged 18 to 62 years were collected. Both total QOLIE-89 and overall SOFSE improved over time after epilepsy surgery (adjusted p value 0.001 and 0.002, respectively, with Bonferroni's correction). Total QOLIE-89 improved 3 months after surgery, while overall SOFSE showed no significant improvement until 6 months after surgery. The presurgical Full-Scale Intelligence Quotient (FSIQ) of the Wechsler Adult Intelligence Scale-III and years of education were significantly associated with time-dependent improvement for both total QOLIE-89 and overall SOFSE (p value 0.001). At one year after surgery, overall SOFSE and total QOLIE-89 scores were significantly higher in the seizure-free group than in the nonseizure-free group (p value = 0.040 and 0.032, respectively).Social functioning significantly improved in people with epilepsy after surgery as QoL, but it took more time to exhibit improvement. People with better FSIQ and more years of education had better improvement in social functioning over time. The early intervention of rehabilitation programs after epilepsy surgery might be necessary to facilitate the improvement in social functioning.
