Youth placed in RC for serious behavior problems had significantly higher use of stimulants than those with other placement reasons. Psychotropics were not used below age 6 years, and although the use of antidepressants and antipsychotics overall increased with age, stimulants were mostly used by 6-16-year olds. The girl/boy ratio for any psychotropic medication use in RC was 1.4 (95% confidence interval [95% CI] 1.1-1.6), significantly higher than the corresponding ratio in GenPop 1.0 (95% CI 0.9-1.0). Conclusion The present findings do not necessarily suggest an overtreatment with medication in RC. However, the frequent short-term use of antipsychotics, presumably for non-psychotic symptoms, is a concern, as it may reflect that the youth are not provided with the recommended first-line psychological treatments.Neuromyelitis optica spectrum disorder (NMOSD) is a rare inflammatory demyelinating disorder of the central nervous system (CNS). Aquaporin-4 (AQP4) antibodies in the serum are highly specific for the diagnosis of NMOSD, but the sensitivity remains under 90% allowing for diagnosis of AQP4 IgG seronegative disease. It remains of crucial importance to identify seronegative NMOSD myelitis as early as the first attack to initiate long-term treatment that will reduce future relapses and disability and to avoid potentially harmful treatments such as those of multiple sclerosis (MS). Over the years, many spinal imaging features have been reported to favour the diagnosis of NMOSD, but only longitudinally extensive transverse myelitis (LETM) was specific enough to make the diagnostic criteria in the AQP4 IgG seronegative cases. Bright spotty lesions (BSLs), which are defined as hyperintense lesions on axial T2-weighted images and sometimes associated with T1 low signal, are now reported to h
