We report a case of a young female patient with catatonic features who later turned out to be suffering from an anti-NMDA (N-methyl-D-aspartate)-receptor-antibody encephalitis. A previously healthy 21-year-old woman was admitted to psychiatric inpatient care presenting with acute psychotic behavior with catatonic features. Laboratory tests of serum and CSF (Cerebrospinal fluid), EEG (Electroencephalogram), brain MRI (Magnetic Resonance Imaging) were unremarkable except vague slow wave on EEG. However, subtle cognitive impairment at the bedside examination suggested further imaging studies to rule out possible organic etiology like autoimmune encephalitis. Brain PET (Positron Emission Tomography) and SPECT (Single Photon Emission Computed Tomography) suggested probable inflammation in the brain. In case of autoimmune encephalitis, given the severity of symptoms and worsening course, steroid pulse therapy was initiated promptly even though the diagnosis was not confirmed but presumed at that time. She recovered completely with steroid therapy. Later her disease turned out to be anti-NMDA-receptor-antibody encephalitis by the antibody test which was not available at the time of admission. Psychiatrists need to be aware of autoimmune encephalitis like anti-NMDA-receptor-antibody encephalitis in the differential diagnosis of acute psychosis with catatonic features. Subtle cognitive impairment which tends to be overlooked due to catatonic features might be a clue to suspect the organic etiology.

OBJECTIVES: The aim of this study was to develop a Korean version of a mood chart application on an Android platform. METHODS: This application is based on the traditional mood chart. Eighteen adults with DSM-5 bipolar disorder were enrolled from November 2016 to March 2017. They were asked to rate their daily mood scores and severity of irritability and impulsivity for six months. Their clinicians rated their symptom severity monthly using the Clinical Global Impression-7 (CGI-7) scale. After six months, the participants completed an anonymous questionnaire regarding their satisfaction with the application. RESULTS: Of the 18 patients, one withdrew their consent from this study and six were males (35.3%) ; their mean age was 31.71±8.56 years. The mean follow-up duration was 159.12±49.45 days and the period of application use was 143.65±52.11 days. The mean total response rate was 59.45% and the mean response rate on the same day was 43.06%. The adherence to using the application decreased significantly declined over the duration since enrollment [odds ratio (OR)=1.008, p=0.008] but tended to increase according to age (OR=0.958, p=0.002). The application mood scores were correlated significantly with the manic (β=0.307, p=0.004) and depressive (β=−0.701, p < 0.001) subscale, and the total (β=1.026, p=0.002) of the CGI-7 (linear mixed models). The majority of subjects agreed that the application helped them manage their symptoms (92.86%), stating that the application was easy to use (78.57%). CONCLUSION: This application could be a valid and useful tool to monitor the mood symptoms of patients with bipolar disorder in Korea.

OBJECTIVES: The objective of this study was to investigate the effect of pharmacological treatments for attention-deficit hyperactivity disorder (ADHD) on motor coordination, using the Developmental Coordination Disorder Questionnaire (DCDQ). METHODS: The participants were recruited from April 2015 to November 2016 from the Department of Psychiatry of Asan Medical Center and were treated for 3 months with methylphenidate or atomoxetine. The illness severity at baseline and 3 months were scored using the ADHD Rating Scale (ARS), Clinical Global Impression-Severity Scale (CGI-S) and/or Clinical Global Impression-Improvement Scale (CGI-I). A total of 39 children with ADHD (age 8.0±1.4 years, 36 boys) completed the Advanced Test of Attention (ATA) and their parents completed the DCDQ at baseline and 3 months. The paired t-test, mixed between-within analysis of variance and correlation analysis were used. RESULTS: The CGI-S (p<0.001), ARS (p<0.001), and fine motor/hand writing (p=0.005) on the DCDQ were significantly changed between pre-treatment and post-treatment. When the participants were divided into those who were suspected of having developmental coordination disorder (DCD) (n=23) and those who probably did not (n=16), the control during movement, fine motor/hand writing and general coordination scores on the DCDQ showed the main effects for group (p<0.001, p<0.001 and p<0.001, respectively). The fine motor/hand writing on the DCDQ has a significant main effect for time [F(1,37)=7.31, p=0.010, η2=0.405] and the interaction effect between group and time was also significant [F(1,37)=4.63, p=0.038, η2=0.111]. The baseline visual commission error on the ATA is significantly correlated with the changes in the DCDQ total scores (r=0.330, p=0.040). CONCLUSION: Our results provide preliminary evidence that pharmacological treatment for ADHD improves not only the core symptoms of ADHD, but also the motor coordination. Further studies are needed to confirm the effect of the pharmacological treatment for ADHD on the motor coordination.
