Abstract
INTRODUCTION The ObserVational survey of the Epidemiology, tReatment and Care Of MigrainE (OVERCOME) European Union (EU) is part of an overarching population-based study program that also includes the United States and Japan. Here, we report data on the migraine/severe headache burden and the use of acute medication and healthcare resources in Spain and Germany. METHODS OVERCOME (EU) was an online, non-interventional, cross-sectional survey conducted in adults in Spain and Germany between October 2020 and February 2021. A total migraine cohort was established based on health survey participants who reported headache/migraine in the last 12 months AND identified as having migraine based on modified International Classification of Headache Disorders, third edition criteria OR self-reported physician diagnosis. Data were analyzed for the total migraine cohort and the subcohort with moderate to severe headache attacks, with average pain severity ≥ 5 points, pain duration ≥ 4 h, and at least moderate disability due to migraine [Migraine Disability Assessment (MIDAS) score ≥ 11] over the past 3 months. RESULTS Pain of moderate or severe intensity was the most frequent symptom in the total migraine cohort (n = 19,103/20,756; 92.0%). Proportions of participants reporting severe disability (MIDAS Grade IV), poorer quality of life (QoL; Migraine-Specific QoL Questionnaire), and higher interictal burden (Migraine Interictal Burden Scale-4), generally increased with number of headache days (HDs)/month. Most participants (92.5%) reported current acute migraine/severe headache medication use, although only 39.0% were using triptans. In the moderate to severe attacks subcohort (n = 5547), 48.4% were using triptans, with nonsteroidal anti-inflammatory drugs the most common acute medication. The moderate to severe attacks subcohort also reported poorer QoL and greater pain and disability with increasing HDs/month, although severe interictal burden was reported for ~ 60% of participants regardless of HDs/month. Treatment satisfaction (six-item migraine Treatment Optimization Questionnaire) in those using triptans was generally poor in both total and subcohorts. CONCLUSION High migraine-related burden levels were reported, despite use of acute medication. Although triptans are recommended for moderate to severe migraine attacks in Spanish and German guidelines, less than half of participants were using triptans; treatment satisfaction in those using triptans was generally poor. New tailored treatment options may help address unmet needs in current acute treatment.

Abstract
BACKGROUND AND PURPOSE The estimated prevalence of migraines in South Korea is 6.0%, with affected patients having unmet needs. The efficacy, safety, and tolerability of galcanezumab, a humanized monoclonal antibody, for episodic migraine (EM) prevention was evaluated in South Korean patients. METHODS During the double-blind period of the EVOLVE-2 phase 3 trial, patients with EM were randomized into placebo, 120 mg-galcanezumab, and 240-mg galcanezumab treatment groups. The primary endpoint was the overall mean change from baseline in the number of monthly migraine headache days during the 6-month double-blind period. We conducted a post-hoc analysis of the South Korean cohort in EVOLVE-2. RESULTS Among 98 South Korean patients in the intent-to-treat population, significant changes from baseline were observed in the number of monthly migraine headache days in the 240-mg galcanezumab group compared with the placebo group (-2.64, p=0.013), in the percentage of patients with ≥50% reduction in the number of monthly migraine headache days (120 mg: odds ratio=2.43, p=0.030; 240 mg: odds ratio=2.60, p=0.019), in the number of monthly migraine headache days with acute medication use (120 mg: -2.22, p=0.006; 240 mg: -2.23, p=0.005), and in the Migraine-Specific Quality-of-Life Role Function-Restrictive (120 mg: 8.34, p=0.040). Numerical improvements from baseline were observed relative to the placebo group in at least one galcanezumab group for: the percentage of patients with ≥75% reduction in the number of monthly migraine headache days functional impairment, and disease severity. The most common treatment-emergent adverse event in the combined galcanezumab group was injection site reaction, which led to treatment discontinuation for one patient. CONCLUSIONS Galcanezumab treatment demonstrated efficacy and a favorable safety and tolerability profile in South Korean patients with EM.

Abstract
BACKGROUND Insights into the burden, needs and treatment of migraine from internet-based surveys in diverse real-world migraine populations are needed, especially at a time when novel preventive migraine medications are becoming part of the therapeutic armamentarium. The objectives of this analysis are to describe traditional preventive (orals and onabotulinum toxin A) treatment patterns in the OVERCOME (EU) study migraine cohort, as well as treatment patterns and patient satisfaction with current treatment in a subgroup of respondents eligible for migraine preventive medication. METHODS The cross-sectional non-interventional OVERCOME (EU) study was conducted (October 2020-February 2021) via an online survey among adults (aged ≥ 18 years) resident in Germany or Spain. Participants, registered in existing online panels, who were willing to provide consent were considered. The migraine cohort included participants reporting headache/migraine in the past year, identified based on a validated migraine diagnostic questionnaire and/or self-reported physician diagnosis. A subgroup of survey respondents defined as eligible for migraine preventive medication at the point in time the cross-sectional survey was taken was also analysed. Variables assessed included sociodemographic and migraine-related clinical characteristics, preventive (traditional and calcitonin gene-related peptide monoclonal antibodies) treatment patterns and patient satisfaction with current treatment. Results are descriptive only. RESULTS Of the 20,756 participants in the migraine cohort, 78.5% sought professional medical care, 50.8% received a migraine diagnosis and only 17.7% had ever used preventive medication. Half (53.3%) of participants currently using preventives took their most recent medication for six months or less. Most patients (73.9%) classified as eligible for preventive medication (based on headache frequency and/or at least moderate disability due to migraine) reported not using traditional preventives and many of those who did (66.8%) were not satisfied with their current standard of care. CONCLUSIONS Our findings highlight the low proportion of people diagnosed with migraine despite a higher rate of consultation and suggest the need for better access to treatment for people with migraine and new preventive therapies with improved efficacy and safety profiles to improve adherence and patient satisfaction.

Abstract
Background and Purpose Several studies have found that the prevalence of migraine is higher among healthcare professionals than in the general population. Furthermore, several investigations have suggested that the personal experiences of neurologists with migraine can influence their perception and treatment of the disease. This study assessed these relationships in Korea. Methods A survey was used to investigate the following characteristics among neurologists: 1) the prevalence rates of migraine, primary stabbing headache, and cluster headache, and 2) their perceptions of migraine and the pain severity experienced by patients, diagnosing migraine, evaluation and treatment patterns, and satisfaction and difficulties with treatment. Results The survey was completed by 442 actively practicing board-certified Korean neurologists. The self-reported lifetime prevalence rates of migraine, migraine with aura, primary stabbing headache, and cluster headache were 49.8%, 12.7%, 26.7%, and 1.4%, respectively. Few of the neurologists used a headache diary or validated scales with their patients, and approximately half were satisfied with the effectiveness of preventive medications. Significant differences were observed between neurologists who had and had not experienced migraine, regarding certain perceptions of migraine, but no differences were found between these groups in the evaluation and preventive treatment of migraine. Conclusions The high self-reported lifetime prevalence rates of migraine and other primary headache disorders among Korean neurologists may indicate that these rates are underreported in the general population, although potential population biases must be considered. From the perspective of neurologists, there is an unmet need for the proper application of headache diaries, validated scales, and effective preventive treatments for patients. While the past experiences of neurologists with migraine might not influence how they evaluate or apply preventive treatments to migraine, they may influence certain perceptions of the disease.

Abstract
BACKGROUND Migraine is a neurological, primary headache disorder affecting more than 1 billion people worldwide, with a multi-faceted burden that can significantly impact the everyday life of a patient, both during and between attacks. However, studies on patient awareness, burden, and clinical management of migraine in Korea are limited and outdated. The aim of this study was to comprehensively investigate the current difficulties and unmet needs that Korean patients with migraine encounter from their perspective. METHODS A total of 207 patients with episodic or chronic migraine aged between 15 and 76 years, completed a survey designed to cover the following topics: diagnosis, understanding of the disease, treatment experience, disability, and quality of life. Patients were recruited by their neurologists from 11 specialized headache clinics in Korea and completed the survey between 22 July and 19 August 2019. Validated scales such as the Migraine Disability Assessment (MIDAS) questionnaire and Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) were used to assess levels of disability and quality of life, respectively, in patients. RESULTS On average, it took 10.1 years from onset of symptoms to diagnosis and a mean of 3.9 hospitals were visited for treatment prior to the patient's current hospital. There was a lack of understanding among respondents about migraine, with 55.6% believing that unilateral headache is a unique feature of migraine compared with other headache disorders. On average, high levels of disability and poor quality of life were reported by patients, as assessed by MIDAS and MSQv2.1, respectively, but only 23.7% had regularly taken preventive medication in the past. Overall satisfaction with previous doctor-patient relationships was reported by 29.5% of respondents, and satisfaction with preventive and acute medications by only 40.8% and 27.1% of the respondents, respectively. CONCLUSION Korean patients with migraine experience significant disability and reduced quality of life as a result of the disease and have clear unmet needs in terms of diagnosis, understanding of the disease, and disease management including treatment.

Abstract
OBJECTIVE Migraine is a chronic, disabling neurological disease affecting >1 billion people worldwide. Migraine remains undertreated in Asia, including Taiwan. Galcanezumab is a humanized monoclonal antibody that selectively binds calcitonin gene-related peptide, a peptide firmly established in the pathophysiology of migraine, with demonstrated efficacy and safety in patients with episodic or chronic migraine. Our objective was to evaluate the efficacy and safety of galcanezumab in Taiwanese patients with episodic or chronic migraine. METHODS We conducted a sub-group analysis of the Taiwanese cohort from two double-blind, placebo-controlled, Phase 3 clinical trials of galcanezumab in the prevention of episodic and chronic migraine, EVOLVE-2 (NCT02614196) and REGAIN (NCT02614261), respectively. During the EVOLVE-2 and REGAIN double-blind periods, 2092 patients were randomly assigned to receive monthly injections of either placebo, 120 mg galcanezumab (240 mg loading dose), or 240 mg galcanezumab. In REGAIN, a 9-month open-label period followed. Post-hoc analysis on the Taiwanese population across both trials included 106 patients, 45 of whom continued into the open-label period in REGAIN. RESULTS Our findings show that galcanezumab has similar efficacy and safety in the Taiwanese population, as compared to the "All Patients" population included in the study. Galcanezumab treatment reduced the number of monthly migraine headache days, determined a higher percentage of patients with a ≥ 50% response, and positively impacted quality of life. CONCLUSION Galcanezumab is a promising therapeutic for the preventive treatment of migraine in the Taiwanese population.

Abstract
BACKGROUND The GERAS II study aimed to assess societal costs and resource use associated with Alzheimer's disease (AD) for patients and their primary caregivers in Italy and Spain, stratified for different severity stages of AD at baseline. This report presents baseline results for Italy. DESIGN GERAS II was a prospective, multicentre, observational study of routine care in AD. SETTING Community-dwelling patients attending specialist secondary care centres (memory clinics/Alzheimer's Evaluation Units) and their primary informal caregivers were recruited into the study. PARTICIPANTS Patients were aged ≥55 years, presented within the normal course of care, had a diagnosis of probable AD and a Mini-Mental State Examination (MMSE) score of ≤26. Patients and caregivers were stratified according to patient AD dementia severity at baseline: mild, MMSE score 21-26; moderate, MMSE score 15-20; or moderately severe/severe, MMSE score <15. MEASUREMENTS Data collected for patients and caregivers included demographics/clinical characteristics; current medication; patient cognitive, functional and behavioural assessments; patient and caregiver health-related quality of life (HRQoL); and patient and caregiver resource use. The costs associated with the resources used were calculated. Costs were broken down into patient healthcare costs, patient social care costs and caregiver informal care costs. RESULTS Of 198 patients enrolled from Italy, 29 (15%) had mild AD dementia, 80 (40%) had moderate AD dementia, and 89 (45%) had moderately severe/severe AD dementia. Patient and caregiver characteristics showed some differences between AD dementia severity groups; for example, a numerically higher proportion of patients with mild and moderately severe/severe AD dementia were taking memantine compared with those with moderate AD dementia. Patient functioning and behavioural and psychological symptoms worsened with increasing AD dementia severity (p<0.05 between groups for all measures). No significant difference between the disease severity groups was observed in patient HRQoL, and there was no clear pattern in resource use. However, all measures of caregiver time spent helping the patient differed significantly between groups (p<0.05) and were highest in patients with moderately severe/severe AD dementia. Mean (standard deviation) total monthly societal costs per patient (2013 values) were €1850 (1901), €1552 (1322) and €2728 (2184) for patients with mild, moderate and moderately severe/severe AD dementia, respectively (p<0.001 between groups). Caregiver informal care costs were the greatest contributor to total societal costs and amounted to €1370, €1223 and €2223 per patient per month for mild, moderate and moderately severe/severe AD dementia groups, respectively (p<0.001 between groups). CONCLUSION Total Italian societal costs generally increased with increasing AD dementia severity. However, costs were slightly lower for moderate than for mild AD dementia, possibly reflecting the observed unusual trend of greater caregiver time and higher memantine use in patients with mild versus moderate AD dementia.

Abstract
Background Comparison of disease progression between placebo-group patients from randomised controlled trials (RCTs) and real-world patients can aid in assessing the generalisability of RCT outcomes. This analysis compared outcomes between community-dwelling patients with mild Alzheimer’s disease (AD) dementia from two RCTs (pooled European (EU) data from EXPEDITION and EXPEDITION 2) and similar patients from the EU GERAS observational study. Methods Data from placebo-group patients with mild AD dementia from the RCTs (EU countries only) were compared with data from GERAS patients with mild AD dementia. Between-group differences for changes over 18 months were analysed for cognition, functioning, neuropsychiatric symptoms, health-related quality of life (HRQoL) and caregiver time using propensity score-adjusted models. A sensitivity analysis compared EU/North American (EU/NA) EXPEDITION patients with GERAS patients. Results EU EXPEDITION patients (n = 168) were younger than GERAS patients (n = 566) (mean (standard deviation, SD) age 71.9 (7.4) versus 77.3 (6.9) years; p < 0.001) and were more likely to use AD treatment (95% versus 84%; p < 0.001). Cognitive performance was similar at baseline in both populations, although GERAS patients showed greater functional impairment (p = 0.005) and lower HRQoL (p < 0.05). At 18 months, no statistically significant differences between EXPEDITION (n = 133) and GERAS (n = 417) patients were observed for changes in cognitive, functional, neuropsychiatric and HRQoL outcomes. Least squares mean (95% confidence interval) change in caregiver time (hours/month) spent on instrumental activities of daily living (iADL; 29.22 (19.16, 39.27) versus 3.20 (−11.89, 18.28), p = 0.001) and supervision (66.59 (47.49, 85.69) versus 3.04 (−25.39, 31.48), p < 0.001) showed greater increases in GERAS than EXPEDITION. In the sensitivity analysis, changes in neuropsychiatric and HRQoL scores and caregiver time spent on basic ADL were also significantly greater in GERAS than in EU/NA EXPEDITION patients. Conclusions Patients with mild AD dementia participating in the EU EXPEDITION RCTs and the GERAS observational study showed a similar decline in cognitive, functional and neuropsychiatric symptoms over 18 months, whereas changes in caregiver time measures were significantly greater in GERAS. Results indicate the importance of using similar regions when comparing real-world and RCT data. Trial registration ClinicalTrials.gov NCT00905372 EXPEDITION. Registered 18 May 2009.

Abstract
OBJECTIVES Evaluate the reliability of using diagnosis codes and prescription data to identify the timing of symptomatic onset, cognitive assessment and diagnosis of Alzheimer's disease (AD) among patients diagnosed with AD. METHODS This was a retrospective cohort study using the UK Clinical Practice Research Datalink (CPRD). The study cohort consisted of a random sample of 50 patients with first AD diagnosis in 2010-2013. Additionally, patients were required to have a valid text-field code and a hospital episode or a referral in the 3 years before the first AD diagnosis. The earliest indications of cognitive impairment, cognitive assessment and AD diagnosis were identified using two approaches: (1) using an algorithm based on diagnostic codes and prescription drug information and (2) using information compiled from manual review of both text-based and coded data. The reliability of the code-based algorithm for identifying the earliest dates of the three measures described earlier was evaluated relative to the comprehensive second approach. Additionally, common cognitive assessments (with and without results) were described for both approaches. RESULTS The two approaches identified the same first dates of cognitive symptoms in 33 (66%) of the 50 patients, first cognitive assessment in 29 (58%) patients and first AD diagnosis in 43 (86%) patients. Allowing for the dates from the two approaches to be within 30 days, the code-based algorithm's success rates increased to 74%, 70% and 94%, respectively. Mini-Mental State Examination was the most commonly observed cognitive assessment in both approaches; however, of the 53 tests performed, only 19 results were observed in the coded data. CONCLUSIONS The code-based algorithm shows promise for identifying the first AD diagnosis. However, the reliability of using coded data to identify earliest indications of cognitive impairment and cognitive assessments is questionable. Additionally, CPRD is not a recommended data source to identify results of cognitive assessments.

Abstract
AIMS To evaluate the impact of amyloid PET imaging on diagnosis and patient management in a multicenter, randomized, controlled study. METHODS Physicians identified patients seeking a diagnosis for mild cognitive impairment or dementia, possibly due to Alzheimer disease (AD), and recorded a working diagnosis and a management plan. The patients underwent florbetapir PET scanning and were randomized to either immediate or delayed (1-year) feedback regarding amyloid status. At the 3-month visit, the physician updated the diagnosis and recorded a summary of the actual patient management since the post-scan visit. The study examined the impact of immediate versus delayed feedback on patient diagnosis/management at 3 and 12 months. RESULTS A total of 618 subjects were randomized (1:1) to immediate or delayed feedback arms, and 602 subjects completed the 3-month primary endpoint visit. A higher proportion of patients in the immediate feedback arm showed a change in diagnosis compared to the controls (32.6 vs. 6.4%; p = 0.0001). Similarly, a higher proportion of patients receiving immediate feedback had a change in management plan (68 vs. 55.5%; p < 0.002), mainly driven by changes in AD medication. Specifically, acetylcholinesterase inhibitors were prescribed to 67% of the amyloid-positive and 27% of the amyloid-negative subjects in the information group compared with 56 and 43%, respectively, in the control group (p < 0.0001). These between-group differences persisted until the 12-month visit. CONCLUSION Knowledge of the amyloid status affects the diagnosis and alters patient management.

Abstract
Background: Improved understanding of the pattern of cognitive decline in Alzheimer’s disease (AD) would be useful to assist primary care physicians in explaining AD progression to patients and caregivers. Objective: To identify the sequence in which cognitive abilities decline in community-dwelling patients with AD. Methods: Baseline data were analyzed from 1,495 patients diagnosed with probable AD and a Mini-Mental State Examination (MMSE) score ≤ 26 enrolled in the 18-month observational GERAS study. Proportional odds logistic regression models were applied to model MMSE subscores (orientation, registration, attention and concentration, recall, language, and drawing) and the corresponding subscores of the cognitive subscale of the Alzheimer’s Disease Assessment Scale (ADAS-cog), using MMSE total score as the index of disease progression. Probabilities of impairment start and full impairment were estimated at each MMSE total score level. Results: From the estimated probabilities for each MMSE subscore as a function of the MMSE total score, the first aspect of cognition to start being impaired was recall, followed by orientation in time, attention and concentration, orientation in place, language, drawing, and registration. For full impairment in subscores, the sequence was recall, drawing, attention and concentration, orientation in time, orientation in place, registration, and language. The sequence of cognitive decline for the corresponding ADAS-cog subscores was remarkably consistent with this pattern. Conclusion: The sequence of cognitive decline in AD can be visualized in an animation using probability estimates for key aspects of cognition. This might be useful for clinicians to set expectations on disease progression for patients and caregivers.

Abstract
Background/Aims We assessed whether cognitive and functional decline in community-dwelling patients with mild Alzheimer disease (AD) dementia were associated with increased societal costs and caregiver burden and time outcomes. Methods Cognitive decline was defined as a ≥3-point reduction in the Mini-Mental State Examination and functional decline as a decrease in the ability to perform one or more basic items of the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory (ADCS-ADL) or ≥20% of instrumental ADL items. Total societal costs were estimated from resource use and caregiver hours using 2010 costs. Caregiver burden was assessed using the Zarit Burden Interview (ZBI); caregiver supervision and total hours were collected. Results Of 566 patients with mild AD enrolled in the GERAS study, 494 were suitable for the current analysis. Mean monthly total societal costs were greater for patients showing functional (+61%) or cognitive decline (+27%) compared with those without decline. In relation to a typical mean monthly cost of approximately EUR 1,400 at baseline, this translated into increases over 18 months to EUR 2,254 and 1,778 for patients with functional and cognitive decline, respectively. The number of patients requiring supervision doubled among patients showing functional or cognitive decline compared with those not showing decline, while caregiver total time increased by 70 and 33%, respectively and ZBI total score by 5.3 and 3.4 points, respectively. Conclusion Cognitive and, more notably, functional decline were associated with increases in costs and caregiver outcomes in patients with mild AD dementia.

Abstract
Background: Timely diagnosis of Alzheimer’s disease (AD) refers to a diagnosis at the stage when patients come to the attention of clinicians because of concerns about changes in cognition, behavior, or functioning and can be still free of dementia and functionally independent. Objectives: To comprehensively review existing scientific evidence on the benefits and potential challenges of making a timely diagnosis of AD. Methods: Relevant studies were identified by searching electronic databases (Medline, Embase) and bibliographies for studies published in English between 1 January 2000 and 2 June 2014 on the consequences of a timely diagnosis of AD. Results: Nine studies were identified that investigated the consequences of diagnosing AD at the initial stages; none were specifically focused on prodromal AD. A timely diagnosis potentially offers the opportunities of early intervention, implementation of coordinated care plans, better management of symptoms, patient safety, cost savings, and postponement of institutionalization. Barriers to making a timely diagnosis include stigma, suicide risk, lack of training, diagnostic uncertainty, shortage of specialized diagnostic services, and the reluctance of healthcare providers to make a diagnosis when no effective disease-modifying options are available. Conclusions: Despite its potential benefits, few published studies have explored the advantages or risks of a timely diagnosis of AD. In light of the cultural shift toward diagnosis at the initial stage of the disease continuum, when the patient does not yet have dementia, more investigations are needed to evaluate the benefits and address the barriers that may impede making a timely AD diagnosis.

Abstract
AIMS To assess how hippocampal volume (HV) from volumetric magnetic resonance imaging (vMRI) is related to the amyloid status at different stages of Alzheimer's disease (AD) and its relevance to patient care. METHODS We evaluated the ability of HV to predict the florbetapir positron emission tomography (PET) amyloid positive/negative status by group in healthy controls (HC, n = 170) and early/late mild cognitive impairment (EMCI, n = 252; LMCI, n = 136), and AD dementia (n = 75) subjects from the Alzheimer's Disease Neuroimaging Initiative Grand Opportunity (ADNI-GO) and ADNI2. Logistic regression analyses, including elastic net classification modeling with 10-fold cross-validation, were used with age and education as covariates. RESULTS HV predicted amyloid status only in LMCI using either logistic regression [area under the curve (AUC) = 0.71, p < 0.001] or elastic net classification modeling [positive predictive value (PPV) = 72.7%]. In EMCI, age (AUC = 0.70, p < 0.0001) and age and/or education (PPV = 63.1%), but not HV, predicted amyloid status. CONCLUSION Using clinical neuroimaging, HV predicted amyloid status only in LMCI, suggesting that HV is not a biomarker surrogate for amyloid PET in clinical applications across the full diagnostic spectrum.

Abstract
OBJECTIVES This study aimed to describe the baseline characteristics of informal carers of community-living Alzheimer's disease (AD) patients by AD severity group and to identify factors associated with two measures of caregiver burden. DESIGN AND SETTING GERAS is a prospective observational study in France, Germany, and the UK, designed to assess costs and resource use associated with AD, for patients and their caregivers, stratified by disease severity. PARTICIPANTS 1497 community-dwelling AD patients and their primary caregivers. MEASUREMENTS Subjective caregiver burden assessed using the Zarit Burden Interview [ZBI] and time spent supervising patients (an objective measure of burden recorded using the Resource Utilization in Dementia instrument) during the month before the baseline visit were recorded. Separate multiple linear regression analyses using ZBI total score and caregiver supervision time as dependent variables were performed to identify patient and caregiver factors independently associated with caregiver burden. RESULTS Increasing AD severity was associated with both subjective caregiver burden (ZBI total score) and overall caregiver time, which includes supervision time (both p<0.001, ANOVA). Better patient functioning (on instrumental activities of daily living) was independently associated with both a lower ZBI total score and less supervision time, whereas higher levels of caregiver distress due to patient behavior were associated with greater caregiver burden. Other factors independently associated with an increased ZBI total score included younger caregiver age, caregiver self-reported depression, caring for a male patient, and longer time since AD diagnosis. Caregivers living with the patient, being a male caregiver, patient living in a rural location, higher patient behavioral problem subdomain scores for apathy and psychosis, more patient emergency room visits, not receiving food delivery and receiving financial support for caregiving were all associated with greater caregiver supervision time. CONCLUSION Our results show that subjective caregiver burden and caregiver time are influenced by different factors, reinforcing the need to consider both aspects of caregiving when trying to minimize the burden of AD. However, interventions that minimize caregiver distress and improve patient functioning may impact on both subjective and objective burden.

Abstract
BACKGROUND/AIMS To examine factors influencing the caregiver burden in adult-child and spousal caregivers of community-dwelling patients with Alzheimer's disease (AD). METHODS Baseline data from the 18-month, prospective, observational GERAS study of 1,497 patients with AD in France, Germany, and the UK were used. Analyses were performed on two groups of caregivers: spouses (n = 985) and adult children (n = 405). General linear models estimated patient and caregiver factors associated with subjective caregiver burden assessed using the Zarit Burden Interview. RESULTS The caregiver burden increased with AD severity. Adult-child caregivers experienced a higher burden than spousal caregivers despite spending less time caring. Worse patient functional ability and more caregiver distress were independently associated with a greater burden in both adult-child and spousal caregivers. Additional factors were differentially associated with a greater caregiver burden in both groups. In adult-child caregivers these were: living with the patient, patient living in an urban location, and patient with a fall in the past 3 months; in spouses the factors were: caregiver gender (female) and age (younger), and more years of patient education. CONCLUSION The perceived burden differed between adult-child and spousal caregivers, and specific patient and caregiver factors were differentially associated with this burden.

Abstract
OBJECTIVE Depression is a comorbidity affecting quality of life (QoL) in patients with Parkinson's disease (PD) and requires appropriate treatment. This study evaluated the tolerability, safety, and efficacy of duloxetine 60 mg once daily for 12 weeks in PD patients with major depressive disorder (MDD). RESEARCH AND DESIGN METHODS Non-comparative, open-label, multi-center study. MAIN OUTCOME MEASURES Tolerability was evaluated by discontinuation rate (acceptable if ≤ 19%) due to treatment-emergent adverse events (TEAEs) and motor symptoms (UPDRS). Safety measures were TEAEs, the UKU side effect rating scale, vital signs, weight, laboratory tests, and ECG. Efficacy measures included HAMD-17, BDI, CGI-S, PGI-I, and pain VAS. QoL was measured by PDQ-39. RESULTS Of the 151 patients enrolled, 8.6% (95% upper CI: 13.3%) discontinued the study due to TEAEs. Worsening in PD-related tremor and rigidity was not observed, activities of daily living significantly improved and UKU subscales progressively decreased. Clinically significant abnormalities in laboratory findings were limited to four cases of hypercholesterolemia and one increase of total bilirubin, CPK, and fasting glucose. Blood pressure, weight, and ECG did not change from baseline. HAMD-17 and PDQ-39 total score and individual domains, BDI, CGI-S, and PGI-I total scores significantly improved. CONCLUSIONS Duloxetine seems well tolerated and likely effective in the treatment of depression associated with PD, with no detrimental effects in PD signs and symptoms.

Abstract
OBJECTIVE The primary aim of this study was to assess the efficacy of atomoxetine in improving ADHD and ODD symptoms in paediatric patients with ADHD and comorbid oppositional defiant disorder (ODD), non-responders to previous psychological intervention with parent support. METHODS This was a multicentre, randomised, placebo-controlled trial conducted in patients aged 6-15 years, with ADHD and ODD diagnosed according to the DSM-IV criteria by a structured clinical interview (K-SADS-PL). Only subjects who are non-responders to a 6-week standardized parent training were randomised to atomoxetine (up to 1.2 mg/kg/day) or placebo (in a 3:1 ratio) for the following 8-week double blind phase. RESULTS Only 2 of the 156 patients enrolled for the parent support phase (92.9% of males; mean age: 9.9 years), improved after the parent training program; 139 patients were randomised for entering in the study and 137 were eligible for efficacy analysis. At the end of the randomised double blind phase, the mean changes in the Swanson, Nolan and Pelham Rating Scale-Revised (SNAP-IV) ADHD subscale were -8.1+/-9.2 and -2.0+/-4.7, respectively in the atomoxetine and in the placebo group (p<0.001 between groups); changes in the ODD subscale were -2.7+/-4.1 and -0.3+/-2.6, respectively in the two groups (p=0.001 between groups). The CGI-ADHD-S score decreased in the atomoxetine group (median change at endpoint: -1.0) compared to no changes in the placebo group (p<0.001 between groups). Statistically significant differences between groups, in favour of atomoxetine, were found in the CHIP-CE scores for risk avoidance domain, emotional comfort and individual risk avoidance subdomains. An improvement in all the subscales of Conners Parents (CPRS-R:S) and Teacher (CTRS-R:S) subscales was observed with atomoxetine, except in the cognitive problems subscale in the CTRS-R:S. Only 3 patients treated with atomoxetine discontinued the study due to adverse events. No clinically significant changes of body weight, height and vital signs were observed in both groups. CONCLUSIONS Treatment with atomoxetine of children and adolescents with ADHD and ODD, who did not initially respond to parental support, was associated with improvements in symptoms of ADHD and ODD, and general health status. Atomoxetine was well tolerated.

Abstract
Attention-deficit hyperactivity disorder (ADHD) is one of the most common neurobehavioural disorders in children. It has been shown that as many as 85% of patients with ADHD have at least one psychiatric co-morbidity, and approximately 60% have at least two. Atomoxetine is a specific, noradrenergic reuptake inhibitor that provides an effective treatment option for patients with ADHD and co-morbid conditions. The efficacy of atomoxetine in treating ADHD appears to be unaffected by the presence of co-morbid conditions. Therapy with atomoxetine has been associated with statistically significant improvements in symptoms of oppositional defiant disorder in most, but not all, studies. Limited data suggest this agent may have potential in improving co-occurring symptoms of anxiety and may be useful in patients with co-morbid conditions such as tics or Tourette's syndrome. The tolerability profile of atomoxetine in patients with ADHD and co-morbid conditions was similar to that of patients with uncomplicated ADHD. Atomoxetine was well tolerated, with adverse events generally mild and transient; the most frequent adverse events in patients with ADHD included abdominal pain, decreased appetite, nausea and vomiting. The favourable safety and efficacy profile of atomoxetine makes it a promising treatment for patients with ADHD and associated co-morbidities.

Abstract
Hypothalamic-pituitary-adrenal (HPA) axis dysfunction has been reported to be involved in vulnerability to alcohol and drug dependence in humans, possibly underlying both addictive behaviour and depression susceptibility. The aim of the present study was to investigate the possible interactions between childhood adverse experiences, depressive symptoms and HPA axis function in addicted patients, in comparison with healthy control. Eighty-two abstinent heroin or cocaine dependent patients and 44 normal controls, matched for age and sex, completed the symptoms Check List-90 (SCL-90), measuring depressive symptoms, and the Childhood Experience of Care and Abuse Questionnaire. Blood samples were collected to determine adrenocorticotropic hormone (ACTH) and cortisol basal plasma levels at 8:00 and 8:30 a.m. Addicted individuals showed significantly higher neglect and depression scores and ACTH-cortisol plasma levels respect to control subjects. Depression scores at SCL-90 in addicted patients positively correlated with plasma ACTH and cortisol values. In turn, plasma ACTH levels were directly associated with childhood neglect measures, reaching statistical significance with 'mother-neglect' scores. Plasma cortisol levels were related to 'father antipathy' among cocaine addicts. These findings suggest the possibility that childhood experience of neglect and poor parent-child attachment may have a persistent effect on HPA axis function as an adult, partially contributing, together with genetic factors and other environmental conditions, to both depressive traits and substance abuse neurobiological vulnerability.

Abstract
BACKGROUND Increasing numbers of reports have raised concerns about significant increases in weight and adiposity over both short- and long-term treatment in patients treated with antipsychotics (APs). The management of overweight and obesity in patients treated with APs has included pharmacological interventions, dietary suggestions, and behavioral strategies. Nevertheless, current evidence does not support the use of pharmacological management of this specific type of obesity, and only a limited number of studies have been published regarding prevention and treatment of weight gain with other strategies. OBJECTIVE The aim of this study was to evaluate the effectiveness of an educational intervention (EI) that combines low-calorie diet with increased physical activity to prevent and treat weight gain in patients treated with APs. METHOD Data were from 53 subjects whose body mass index (BMI) had increased by more than 7% after starting an AP therapy and who consented to participate in a 12-week educational intervention study aimed at preventing further weight gain and, when possible, at inducing a weight loss. Weight and BMI were measured at baseline (at each of the monthly follow-up visits) and at study completion 12 weeks from entry in the study. RESULTS Twenty-six patients completed the 12-week program. Completers showed a significant mean body weight decrease of 3.15 kg, with a mean BMI reduction of 1.2 (kg/m) at the end of the 3-month period. CONCLUSIONS Educational intervention can be an important tool for the management of weight increase in patients treated with APs. A larger prospective and controlled study is now needed to confirm our findings.

Abstract
OBJECTIVE A door-to-door two-phase study was designed in order to estimate the prevalence of cognitive deficit amongst the residents of a district in Tuscany (central Italy). Identification of cases with mild cognitive impairment (MCI) was given high priority, because this condition has been suggested as a term for the boundary area between normal aging and dementia. METHODS Of the 1600 subjects who completed the screening phase, 354 scored under the cut-off point of the Mini Mental State Examination and Clinical Dementia Rating and were investigated by means of a standardized diagnostic protocol. RESULTS The prevalence of MCI and age-related cognitive decline was 4.9 and 9.3%, respectively; low levels of education significantly increased the risk of these conditions. The prevalence of dementia over age 65 was 6.2%, with a significant risk association with age. In our population, Alzheimer's disease was the most frequent type of dementia (prevalence rate 4.2%) and increased risk depending on age, sex and education has been found. CONCLUSIONS Our findings are somewhat similar to previous studies. Further epidemiological and longitudinal studies are warranted to identify which diagnostic category is more predictive for dementia.

Abstract
To date the aetiology of Parkinson's disease (PD) is unknown although both genetic susceptibility and environmental factors appear to play an important role in the development of the disease. Recent data have also indicated that chronic exposure to a common pesticide can reproduce the neurochemical, behavioral and neuropathological features of PD. The epidemiological studies previously carried on the prevalence of PD in population exposed to environmental factors have produced controversial results, probably because of different trial design and different analysis methods. A case-control retrospective study was conducted in a well-defined geographic area in Tuscany-Italy with the aim to identify environmental factors possibly related to PD. No significant difference between PD patients and control subjects was observed in time spent in rural or industrial residence, in well water drinking and in the exposure to herbicides and pesticides. A significant difference between patients with PD and controls was reported for cigarette smoking, controls resulting more likely cigarette smokers in comparison with PD patients. The present findings support the view of a protective effect of cigarette smoking and do not show any significant association between environmental factors and the risk of development of PD.

Abstract
Cholinesterase (ChE) inhibitors improve or stabilize cognitive impairment in patients with Alzheimer disease (AD). However, the regional metabolic and perfusion correlates of treatment with ChE inhibitors are not fully known. Twenty-four patients with mild to moderate AD were evaluated with Tc-ethyl cysteinate dimer (ECD) single-photon-emission CT scanning (SPECT), before and after 4.3 +/- 1.1 months of treatment with ChE inhibitors (donepezil, rivastigmine). Clinical evaluations included the Mini-Mental State Examination (MMSE) as well as the Neuropsychiatric Inventory (NPI). Inclusion criterion was a clear favorable response to therapy with ChE inhibitors (MMSE improvement of at least 2 points; total NPI improvement of at least 4 points). SPECT data were analyzed by Statistical Parametric Mapping (SPM 99, Wellcome, Department of Cognitive Neurology, London, UK). SPM analysis showed a significant increase (P < 0.01) of regional cerebral perfusion (rCBF) after short-term ChE inhibitor therapy with respect to baseline in the right anterior cingulate, the dorsolateral prefrontal, and the temporoparietal areas bilaterally. These data suggest that cognitive or behavioral benefits after ChE inhibitor therapy are related to a clear increase of rCBF in crucial areas specifically involved in the attentional and limbic networks.

Abstract
Behavioural disturbances are frequently observed in Parkinson's disease (PD), including mood and anxiety disorders. The existence of a comorbidity between such psychiatric disorders in PD patients has been suggested only in a few studies. To assess the prevalence of mood and anxiety disturbances, and the rate of comorbidity of such disorders in PD. Secondary aim was to correlate the prevalence of psychiatric disorders in PD with age, sex, laterality of motor symptomatology, clinical features, severity of disease, age of onset and PD duration, and anti-parkinsonian therapy. Ninety consecutive PD outpatients, and 90 age- and sex-matched controls were included. All PD patients enrolled were non-fluctuating (21 de novo, 69 treated with levodopa or dopamine agonists). PD patients and controls with Mini Mental State Examination score <23 were excluded. Psychiatric diagnosis was performed by semistructured interview according with DSM-IV criteria and the severity of depressive and anxious symptoms was rated with clinical rating scales. Major depression was found in 21.1% PD patients vs. 3.3% controls (P < 0.01, chi-square analysis), dystimia in 18.8% PD patients vs. 4.4% controls (P < 0.05), panic disorders in 30% PD patients vs. 5.5% controls (P < 0.01). No difference in the prevalence of other anxiety disorders was observed between the two groups. The comorbidity of mood and anxiety disorders was found in 19.3% PD patients vs. 8.6% controls (P < 0.01). No correlation was reported between the prevalence of behavioural disturbances and any of the demographic, clinical or pharmacological data taken into account. Our findings might suggest the existence of a wide spectrum of psychiatric disorders in PD ranging from pure depressive disorders, comorbid depressive and anxiety disorders, and pure anxiety disorders, presumably linked to the same neurobiological substrate.

Abstract
Visual-spatial working memory (WM) impairment is frequently associated with the early stage of Parkinson's disease (PD). The aim of this study was to evaluate the performance of a group of PD patients in visual-spatial and visual-object WM tasks and to investigate the effect of administering the dopaminergic agonist apomorphine (experiment 1) or the dopamine precursor L-dopa (experiment 2) on the performance of tests assessing these functions. To study WM processes, the PD patients and age-matched normal controls were given an n-back task paradigm. In both experiments, the PD patients were submitted to two evaluations: one after a 12-hour therapy washout and the other 15 min after a subcutaneous infusion of apomorphine (average 0.04 mg/kg) or 20/30 min after L-dopa intake (200 mg p.o.). The apomorphine infusion had a worsening effect on reaction times in both visual-spatial and visual-object WM tasks, but it did not influence performance accuracy. Instead, L-dopa administration had a ameliorative effect on accuracy and reaction times in both visual-spatial and visual-object tasks. These results highlight the role of dopamine in the modulation of the WM function in PD patients.

Abstract
Huntington's disease (HD) is characterized by chorea, cognitive and behavioral changes. Amantadine, a non-competitive NMDA receptor antagonist, has shown an antidyskinetic effect on levodopa-induced dyskinesias, which are known to have strict pathogenetic analogies with choreic hyperkinesias. The antidyskinetic efficacy of amantadine and its effects on cognitive and behavioural symptoms were evaluated. Eight HD patients received oral amantadine (100 mg tid) unblinded for a 1-year period. A significant reduction of dyskinesias was reported ( p<0.01). No changes were observed in neuropsychologic and psychiatric assessments after 6 and 12 months of therapy. These data may have relevance to the treatment of HD with amantadine.

Abstract
PURPOSE the aim of this experimental study was to evaluate the attention modulating actions on the polysynaptic component of blink reflex responses and especially of the R3 component in patients suffering from Parkinson's Disease (PD). To this end, a non-task warning paradigm was adopted. METHODS attention processing was evaluated by means of a non-task paradigm in 55 patients suffering from PD. Subjects were presented with a visual 'warning' prestimulus and the blink reflex (BR) analyzed with special regard for any modulation of its polysynaptic components (R2-R3). RESULTS The mean amplitude of the post-warning R3 component (PW-R3c) of 'de novo' PD patients was 62% of the corresponding component following unannounced stimuli, a figure which differs significantly from both treated PD patients (18.9%) and control subjects (15.4%). De novo patients subsequently started on L-dopa therapy exhibited a more pronounced inhibition of the R3 component after warning stimulus, as the PW-R3c percentage decreased. Inversely, treated patients whose therapy was withheld showed decreased inhibition of this component. Regarding R2, the mean PW-R2c in the de novo patients differed slightly from that of the treated patients (P<0.05), but not from that of the control subjects. Such a finding may be attributable to a specific effects on the excitability of the polysynaptic responses. CONCLUSIONS Attention disorders in PD have been well documented by means of this kind of non-task warning paradigm, which appears to probe the modulation of the BR R3 component, even if the interpretation of this R3 changes suggesting a specific alteration of attention processing must be put forward extremely carefully, because something similar, but less evident, appears also for R2.

Abstract
Tardive dystonia represents a complication of long-term use of neuroleptics and its treatment is often unsatisfactory. Atypical neuroleptics appear to improve tardive dystonia, and cases of tardive dystonia successfully managed with clozapine have been reported. The aim of this open-label video-blinded study was to evaluate the antidystonic efficacy of olanzapine, a new atypical neuroleptic with a low risk of agranulocytosis, in a group of four patients (one man and three women) with tardive cervical dystonia. They developed severe dystonia after several years of neuroleptic treatment. Extensive laboratory evaluations, as well as neurophysiologic and neuroradiologic investigations, were negative. Olanzapine was started at a dose of 5 mg/d and increased up to 7.5 mg/d. All patients were evaluated at baseline and after 2, 4, 8, and 12 weeks of treatment, using the Toronto Western Spasmodic Torticollis Rating Scale, and videotaped. At the end of the trial, the videotapes were reviewed and scored by a blind observer. A self-rating visual analog scale completed the disability evaluation.A moderate to marked improvement in dystonia was observed in all patients, and significant differences were observed in Toronto Western Spasmodic Torticollis Rating Scale scores and videotape ratings after 8 and 12 weeks of treatment compared with the basal values (p < 0.05). The average percentage of improvement in Toronto Western Spasmodic Torticollis Rating Scale score and visual analog scale was 26.4% and 42.6%, respectively. No serious side effects were reported at the maximum dosage reached (7.5 mg/d). This study warrants a larger controlled study to conclusively demonstrate the efficacy of olanzapine in tardive dystonia.

Abstract
The idiopathic cerebellar ataxias (IDCA) comprise a wide spectrum of neurodegenerative diseases with heterogeneous neuropathology, characterized by the negativity of search for any known genetic mutation. On the basis of both their clinical presentation and their magnetic resonance imaging pattern, patients with IDCA can be subdivided into patients with a purely cerebellar syndrome and atrophy of the cerebellum (IDCA-C) and patients with additional noncerebellar symptoms and atrophy of both cerebellum and brainstem (IDCA-P). The aim of the present study was to evaluate the disaggregated contribution of brainstem and cerebellum in the control of eye movements, by means of an extensive battery of quantitative tests covering most oculomotor subfunctions related to lesions of the cerebellum and the brainstem. The smooth-pursuit movement analysis showed a decrease in gain and magnitude in both subgroups of IDCA with respect to normal controls, without any significant differences in the prevalence pattern between the two subgroups; the mean values of these parameters, however, were significantly lower in IDCA-P than in IDCA-C subjects in both gain (P < 0.01) and magnitude (P < 0.001). No statistically significant difference was observed between the two subgroups in the analysis of saccadic movements or in the other parameters investigated. The distinction between IDCA-P and IDCA-C subgroups has clinical implications, as a poorer prognosis is related to brainstem involvement, which may occur late in the course of the disease. Thus, the possibility to detect the brainstem involvement, also in association with cerebellar impairment, by a relatively simple eye-movement analysis, potentially useful mainly in follow-up investigations, needs to be evaluated further.

Abstract
Selective serotonin reuptake inhibitors (SSRIs) have been reported to be useful in the treatment of depression in patients with Parkinson's disease (PD). However, a few reports have suggested that SSRIs may worsen parkinsonian motor symptomatology and extrapyramidal side effects have been reported in depressed patients treated with SSRIs. So far, no prospective trial comparing the effects of different SSRIs in depressed patients with PD has been performed. The aim of the present study was to assess the effects of four SSRIs (citalopram, fluoxetine, fluvoxamine, and sertraline) on motor performance and their efficacy on depression in a group of patients with PD. Sixty-two consecutive nondemented, nonfluctuating, depressed patients with PD were included in four treatment groups (15 patiens received citalopram, 16 fluoxetine, 16 fluvoxamine, and 15 sertraline). The evaluation of extrapyramidal and depressive symptomatology was performed with use of the Unified Parkinson's Disease Rating Scale (UPDRS), Beck Depression Inventory, and Hamilton Depression Rating Scale at baseline and after 1, 3, and 6 months. Fifty-two patients completed the study. UPDRS scores were not significantly modified by the add-on therapy with each of the SSRIs studied. A significant improvement in depressive symptoms from baseline to the end of the trial was obtained with all SSRIs (Beck and Hamilton scores improving; p < 0.05 according to an analysis of variance). Our findings suggest that SSRIs do not significantly worsen extrapyramidal symptomatology and may ameliorate depression in patients with PD.

Abstract
Selective serotonin reuptake inhibitors have been used in the treatment of depression in patients with PD. Conflicting data as to whether selective serotonin reuptake inhibitors worsen parkinsonian motor symptomatology have been reported. In this study, the additional 6 months therapy with paroxetine 20 mg/d in a group of depressed patients with PD did not modify parkinsonian motor function (Unified Parkinson's Disease Rating Scale scores); however, in one patient, fully reversible worsening of tremor was observed. Depression, as evaluated by Beck Depression Inventory and Hamilton Depression Rating Scale, improved from baseline to final visit (p < 0.05 by analysis of variance).

Abstract
Tolcapone, a central and peripheral catechol O-methyltransferase (COMT) inhibitor, reduces the conversion of L-Dopa into 3-O-methyl-Dopa (3-OMD), thus leading to more stable and sustained L-Dopa plasma levels. This study was designed to evaluate the effects of acute and 6-week tolcapone administration on L-Dopa pharmacokinetics and pharmacodynamics in Parkinson's disease (PD) patients with predictable motor fluctuations. Tapping test, walking time, and tremor, as well as L-Dopa and 3-OMD plasma levels, were assessed before and for 5 hours after the administration of a single L-Dopa dose, alone or in combination with 200 mg tolcapone, in seven patients with PD. This clinical and pharmacokinetic study was repeated after 6 weeks of tolcapone therapy (200 mg three times daily). It was observed that tolcapone, after both acute and chronic administration, prolonged the motor improvement induced by L-Dopa. As a result, at week 6 of tolcapone therapy, the daily hours spent "off" were significantly decreased. Tolcapone significantly increased the area under the curve of L-Dopa plasma levels by slowing down the elimination of L-Dopa from plasma, whereas the maximal concentration of L-Dopa was not modified. 3-OMD levels decreased significantly after acute tolcapone administration, and after 6 weeks of tolcapone therapy, they were approximately one sixth of pre-tolcapone values. The data confirm that tolcapone decreases L-Dopa clearance and prolongs motor response in PD patients with motor fluctuations, and that this effect is maintained after 6 weeks of tolcapone therapy.

Abstract
Various open and controlled studies have confirmed the antimigraine action of flunarizine, while the antimigraine properties of nimodipine are still open to controversy. Moreover, only a few studies include an additional follow-up after discontinuation of migraine prophylaxis with either drug. We carried out a single blind evaluation of the efficacy and tolerance of flunarizine (25 patients) in comparison with nimodipine (25 patients) and the long-term effect after discontinuation of a 6-month treatment. Both medications significantly reduced migraine frequently and severity. Flunarizine was more efficacious than nimodipine in reducing migraine frequency (p < 0.001), pain severity (p < 0.05), migraine index (p < 0.05) and corrected migraine index (p < 0.05). The positive effect lasted 8.4 +/- 4.0 months after discontinuation of flunarizine and 4.9 +/- 3.5 months after nimodipine (p < 0.05). Our results suggest that flunarizine is more effective than nimodipine in the prophylactic treatment of migraine. The positive effect after drug discontinuation lasts longer with flunarizine, compared to nimodipine.

Abstract
Frequent or regular intake of antimigraine drugs, including analgesics, constitutes a common cause of chronic daily headache. Discontinuation of symptomatic medication can produce an increase in head pain accompanied by withdrawal symptoms. We report the favourable outcome of treating a group of outpatients with the combination of amitriptyline, dexamethasone and sumatriptan. Dexamethasone (4 mg/day) was given intramuscularly for 2 weeks, amitriptyline orally at night (50 mg/day) for at least 6 months, and sumatriptan subcutaneously to treat acute headache attacks. Eighteen out of 20 patients abstained from drug abuse. Eleven of these 18 patients showed a marked reduction in headache frequency (at least 75% in relation to the basal value), and were considered "very good responders". The other seven patients experienced at least 50% reduction in headache frequency compared to baseline. This preliminary report suggests that drug-induced headache can be treated effectively in outpatients using dexamethasone, amitriptyline and sumatriptan in combination with significant benefit in everyday life conditions.
