Besides from medical data, the patients who were previously called as attention disorder, mental instability, moral imbeciles, or moral defectives, can also be identified by exploring literatures and historical figures. In the past, as we can notice from the titles, they were recognized as a 'moral defect group'. And rather than treating them, separation from the society was the main solution. After the endemic encephalitis from 1917 to late 1920s, however, many survivors suffered from behavioral problems similar to those of the previous 'moral defect group' and studies on the relationship between brain damage and behavior problems were started henceforth. After being known as the 'minimal brain dysfunction', it was developed into the current attention-deficit/hyperactivity disorder. While the disease concept changed and developed over time, after numerous trials and errors, treatment medication starting from central nervous system stimulants such as amphetamine and methylphenidate is used for treatment in children and adult patients with ADHD, and most recently non-stimulants such as atomoxetine has become the one of the first line treatment options. Although we went through a thorough verification process of the safety and efficacy of the medication by contemplating the historical development process, we believe that adjustment is needed for remaining concerns on medication abuse and slight differences in disease paradigm and therapeutic philosophy depending on cultures.

Objectives Previous literature on the prescription change among patients with schizophrenia mainly focused on antipsychotics. This study investigated chronological change in the patterns of discharge medication among inpatients with schizophrenia at a psychiatric inpatient unit of a university-affiliated hospital. Methods All admission records at a psychiatric unit of Hanyang University Guri Hospital with discharge diagnosis of schizophrenia during two different five-year time frames (1996-2000 and 2006-2010) were reviewed including the demographic and clinical data and discharge medications. The data were gathered from a total of 207 patients (95 in 1990s and 112 in 2000s). Results The frequency in use of atypical antipsychotics (p < 0.01), antidepressants (p < 0.05), beta-blockers (p < 0.01), and benzodiazepine (p < 0.01) was significantly higher in 2000s. Anticholinergic drugs were less likely used in 2000s (p < 0.01). We did not find significant differences in the equivalent dose of antipsychotic drugs, the use of mood stabilizers and cholinergic drugs between two time frames. Conclusions Increased proportion of atypical antipsychotics and decreased use of anti-parkinsonian drugs are in line with literature. Our results show that more diverse classes of psychotic medications are used for schizophrenia in recent years. It is likely that psychiatrists are becoming more conscious of negative symptoms, anxiety, and depression in the pharmacotherapy of schizophrenia as well as positive symptoms of the illness.

Objectives The purpose of this study was to investigate the difference of brain activity between internet game overusers in adulthood and normal adults in a state of disembodiment. Methods The fMRI images were taken while the internet game overuser group (n = 14) and the control group (n = 15) were asked to perform the task composed of ball-throwing animations. The task reflected on either self-agency about ball-throwing or location of a ball. And each block was shown with either different (changing viewpoint) or same animations (fixed viewpoint). The disembodiment-related condition was the interaction between agency task and changing viewpoint. Results 1) In within-group analyses, the control group exhibited higher brain activation in the left precentral gyrus, the left inferior frontal gyrus, and the left insula. And the overuser group exhibited higher activation in the right cuneus, the left posterior middle occipital gyrus, and the left parahippocampal gyrus. 2) In between-group analyses, the control group exhibited higher activation in the right posterior superior temporal gyrus. And the overuser group exhibited higher activation in the left cuneus, and the left posterior middle occipital area. Conclusions These results show that the disembodiment-related brain activation of internet game overusers in adulthood is different from that of normal adults.

Objectives This study aimed to identify the differences and the profiles of cognitive deficits in remitted patients with schizophrenia and first-degree relatives of schizophrenic probands. Methods A total of 26 remitted states of schizophrenia patients were included in the study and the same number of unaffected first-degree relatives of schizophrenic probands and healthy controls were matched for age, sex, years of education. Cognitive function of all participants was measured by using the Digit span test, the Continuous performance test, the Rey auditory & visual learning test, the Complex figure test, the Verbal fluency test, the Wisconsin card sorting test and the Finger tapping test. The effects of subsyndromal symptomatology and general intelligence score were controlled. Results Schizophrenia patients' group showed more significant impairment than other groups in verbal memory (learning, immediate recall, delayed recall), visual memory (copy, immediate recall, delayed recall) and cognitive flexibility domains. The family group and the patient group commonly performed significantly worse than healthy controls in working memory and verbal fluency (category) tests. There were no differences in sustained attention, psychomotor performance. Conclusions Our research shows that the deficit in working memory and verbal fluency could be strong candidates of endophenotypic marker in schizophrenia.

Objectives More than half of the elders suffer from chronic sleep disturbances. Moreover, sleep disturbances are more prevalent in patients with depressive disorder than in community dwelling elderly. In this study, we aim to estimate the risk factors of poor sleep quality and its effect on quality of life in patients with late life depression. Methods This study included 159 depressive patients aged 65 years or older who completed Pittsburgh Sleep Quality Index (PSQI). A global PSQI score of 5 or greater indicates a poor sleeper. Structural diagnostic interviews were performed using the Korean version of Mini International Neuropsychiatric Interview (MINI). Depression was evaluated by the Korean form of Geriatric Depression Scale (KGDS). Global cognition was assessed by Mini-Mental State Examination in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease assessment packet. Quality of life was evaluated by the Korean version of Short-Form 36-Item Health Survey (SF-36). Results The frequencies of poor sleepers were 90.5% in major depressive disorder, 71.8% in minor depressive disorder, 47.1% in subsyndromal depressive disorder, and 73.0% in all types of depressive disorders. Multivariate logistic regression analysis indicated that female [odds ratio (OR) = 2.83, 95% confidence interval (CI) = 1.20-6.67] and higher KGDS score (OR = 1.13, 95% CI = 1.05-1.21) were risk factors of poor sleep quality in patients with late life depression. In the analysis of ANCOVA adjusted for age, gender, education and KGDS score, the mean scores of vitality mental health and mental component summary of SF-36 were lower in poor sleepers than in good sleepers. Conclusions Poor sleepers among patients with late life depression are very common and are associated with female and higher KGDS scores. Poor sleep quality causes a significant negative effect on mental health quality. So researchers and clinicians should be more vigilant in the evaluation and treatment of sleep disturbances in patients with late life depression.
