Baseline symptom severity predicts serotonin transporter change during psychotherapy in patients with major depression

Volume 70 Issue 1 - January 2015

Clinical impact of 11C-Pittsburgh compound-B positron emission tomography carried out in addition to magnetic resonance imaging and single-photon emission computed tomography on the diagnosis of Alzheimer's disease in patients with dementia and mild cognitive impairment
Yoshie Omachi, Kimiteru Ito, et al.
Volume 69 Issue 12 - December 2015
Introduction
This study investigated a degree of consistency in clinical and research diagnostic criteria of Alzheimer's disease, and the influences of PiB PET on such degree. The evaluation was performed under the present circumstances in Japan, that MRI is used for structural imaging and cerebral blood flow SPECT is used for functional imaging.

Longitudinal association between habitual physical activity and depressive symptoms in older people
Yuko Yoshida, Hajime Iwasa, et al.
Volume 69 Issue 11 - November 2015
Introduction
This is a cohort study investigating the relationship between physical activity and depression symptoms among 950 community-dwelling older people. A state of physical activity and depression of the subjects during a 2-year period from 2002 to 2003 was examined, and 270 subjects who had depression symptoms in 2003 were excluded. The state of depression in 2006 in the remaining 680 subjects was examined, using the Geriatric Depression Scale. The results showed significantly lower rates of depression among subjects who had continued physical activities in 2002 and 2003, compared to the subjects who had not. With regards to the correlation between physical activity and depression, it was difficult to confirm the causality between these two parameters. However, this cohort study demonstrated very interesting results suggesting that physical activity may prevent depression.

Comparison of treatment selections by Japanese and US psychiatrists for major depressive disorder: A case vignette study
Atsuo Nakagawa, Aya Williams, et al.
Volume 69 Issue 9 - September 2015
Introduction
This study investigated a gap between the treatment algorithm and the clinical practices for depression performed by early-career psychiatrists in Japan and the USA. The gap was greater in Japanese psychiatrists. Even though the small sample size is a limitation, this study is valuable due to its social relevance and creativity.

Rare heterozygous truncating variations and risk of autism spectrum disorder: Whole-exome sequencing of a multiplex family and follow-up study in a Japanese population
Emiko Inoue, Yuichiro Watanabe, et al.
Volume 69 Issue 8 - August 2015
Introduction
A genome-wide analysis was performed for autism spectrum disorders in multiplex families, and two rare heterozygous truncating mutations (RPS24 Q191X and CD300LF P261fsX266) were identified. However, the same mutation was not found in another study including 667 individuals in the control group and 243 individuals in the autism spectrum disorder group. The results of the present study indicate that these two heterozygous truncating mutations are risk candidates for autism spectrum disorders. Our results may shed light on the genetic background of autism spectrum disorders in future.

Biological heterogeneity of obsessive–compulsive disorder: A voxel-based morphometric study based on dimensional assessment
Kayo Okada, Tomohiro Nakao, et al.
Volume 69 Issue 7 - July 2015
Introduction
Abnormal orbitofrontal cortical–striatal–thalamic circuit is a well-known feature of obsessive-compulsive disorder (OCD). This study examined brain anatomy in OCD, and reported extensively reduced gray matter. Further, it was revealed that the part of the brain involved varied depending on the symptoms, suggesting that the neural basis of OCD differs depending on the symptoms.

White matter abnormalities in major depressive disorder with melancholic and atypical features: A diffusion tensor imaging study
Miho Ota, Takamasa Noda, et al.
Volume 69 Issue 6 - June 2015
Introduction
This valuable study examined the structural changes in white matter using diffusion tensor imaging to clarify the neurobiological basis of major depressive disorder presenting with atypical features differing from the clinical manifestations, course, and drug reaction of melancholic depression.

Role of cortisol in patients at risk for psychosis mental state and psychopathological correlates: A systematic review
Evangelos Karanikas and Giorgos Garyfallos
Volume 69 Issue 5 - May 2015
Introduction
Many studies to date have examined the role of cortisol, a stress hormone, in schizophrenia. This paper comprises a systematic review of 16 articles related to the role of cortisol in the pathology of the prodromal phase of schizophrenia, which has garnered particular attention recently.

Brain correlates of response inhibition in Internet gaming disorder
Chiao-Yun Chen, Mei-Feng Huang, et al.
Volume 69 Issue 4 - April 2015
Introduction
Internet gaming disorder (IGD) is a psychiatric disorder recently proposed for inclusion in the Diagnostic and Statistical Manual of Mental Disorders (fifth edition) that warrants further study. The authors examined brain activity by functional magnetic resonance imaging during a Go/No-go task to investigate the subjects’ capability of simple reaction control, and found that activation of the supplementary motor area was low in patients with IGD, and the ability to control impulses is therefore reduced in IGD.
