China faces multiple obstacles in preparing to care for its fast-growing dementia population. Better understanding of patients and caregivers may mitigate these challenges by improving awareness and education.
IMPORTANCE Tourette syndrome is a neurodevelopmental disorder characterized by childhood onset of motor and phonic tics, often accompanied by behavioral and psychiatric comorbidities.Deutetrabenazine is a vesicular monoamine transporter 2 inhibitor approved in the US for the treatment of chorea associated with Huntington disease and tardive dyskinesia. OBJECTIVETo report results of the ARTISTS 2 (Alternatives for Reducing Tics in Tourette Syndrome 2) study examining deutetrabenazine for treatment of Tourette syndrome. DESIGN, SETTING, AND PARTICIPANTS This phase 3, randomized, double-blind, placebocontrolled, parallel-group, fixed-dose study was conducted over 8 weeks with a 1-week follow-up (June 21, 2018, to December 9, 2019). Children and adolescents aged 6 to 16 years with a diagnosis of Tourette syndrome and active tics causing distress or impairment were enrolled in the study. Children were recruited from 52 sites in 10 countries. Data were analyzed from February 4 to April 22, 2020. INTERVENTIONS Participants were randomized (1:1:1) to low-dose deutetrabenazine (up to 36 mg/d), high-dose deutetrabenazine (up to 48 mg/d), or a matching placebo, which were titrated over 4 weeks to the target dose followed by a 4-week maintenance period. MAIN OUTCOMES AND MEASURES The primary efficacy end point was change from baseline to week 8 in the Yale Global Tic Severity Scale-Total Tic Score (YGTSS-TTS) for high-dose deutetrabenazine. Key secondary end points included changes in YGTSS-TTS for low-dose deutetrabenazine, Tourette Syndrome Clinical Global Impression score, Tourette Syndrome Patient Global Impression of Impact score, and Child and Adolescent Gilles de la Tourette Syndrome-Quality of Life Activities of Daily Living subscale score. Safety assessments included incidence of treatment-emergent adverse events, laboratory parameters, vital signs, and questionnaires. RESULTSThe study included 158 children and adolescents (mean [SD] age, 11.7 [2.6] years). A total of 119 participants (75%) were boys; 7 (4%), Asian; 1 (1%), Black; 32 (20%), Hispanic; 4 (3%), Native American; 135 (85%), White; 2 (1%), multiracial; 9 (6%), other race; and 1 (0.6%), of unknown ethnic origin. Fifty-two participants were randomized to the high-dose deutetrabenazine group, 54 to the low-dose deutetrabenazine group, and 52 to the placebo group. Baseline characteristics for participants were similar between groups. Of the total 158 participants, 64 (41%) were aged 6 to 11 years, and 94 (59%) were aged 12 to 16 years at baseline. Mean time since Tourette syndrome diagnosis was 3.3 (2.8) years, and mean baseline YGTSS-TTS was 33.8 (6.6) points. At week 8, the difference in YGTSS-TTS was not significant between the high-dose deutetrabenazine and placebo (continued) Key Points Question Are fixed doses of deutetrabenazine up to 48 mg per day safe and effective for the treatment of tics associated with Tourette syndrome in pediatric patients? Findings In this randomized clinical trial of 158 children and adolescents, differences in tic severity b...
IMPORTANCETourette syndrome is a neurodevelopmental disorder characterized by childhood onset of motor and phonic tics; treatments for tics are associated with safety concerns. Deutetrabenazine is a selective vesicular monoamine transporter 2 inhibitor approved for the treatment of chorea associated with Huntington disease and tardive dyskinesia in adults. OBJECTIVE To examine whether deutetrabenazine is effective and safe for the treatment of Tourette syndrome in children and adolescents. DESIGN, SETTING, AND PARTICIPANTS This phase 2/3, randomized, double-masked, placebocontrolled, parallel-group, dose-titration study included children and adolescents (aged 6-16 years) with Tourette syndrome with active tics causing distress or impairment (ie, Yale Global Tic Severity Scale-Total Tic Score [YGTSS-TTS] Ն20). The trial was conducted over 12 weeks, with 1 week of
The impact of dementia care on caregivers' professional, personal, emotional and social well-being was measured in a cohort of 1,387 caregivers in seven regions across mainland China, using a Chinese version of the Zarit Burden Interview (ZBI) and four supplementary questions. Caregivers also estimated costs of care and medical resource utilization. Caregiver burden was generally low to moderate. Dementia care had the greatest impact on caregivers' professional lives, with 25.5% reporting a reduced work schedule in the past month. Lost work time was greater for caregivers of patients with previously diagnosed dementia than for those with newly diagnosed dementia. Average monthly out-of-pocket costs of dementia care exceeded national average monthly incomes of rural and urban residents. These findings highlight the obstacles facing the country with the fastest-growing elderly population in the world.
The 5-HT2 antagonist, trazodone, may be beneficial in the management of SSRI-induced sexual dysfunction. Large-scale, placebo-controlled, double-blind studies with 5-HT2 antagonists are required to substantiate these preliminary observations.
