The term frontotemporal dementia (FTD) refers to a group of neurodegenerative disorders that are associated with atrophy of the frontal and temporal lobes, and present clinically with impairments of behaviour or language. Three main subtypes are described, behavioural variant FTD (bvFTD) and two subtypes of the language presentation (known as primary progressive aphasia or PPA) called semantic variant of PPA and non-fluent variant of PPA. Most imaging studies of FTD have used volumetric T1 magnetic resonance imaging (MRI) or positron emissions tomography imaging to identify patterns of grey matter atrophy or hypometabolism in these different subtypes, but more recently newer imaging techniques have been used to help define abnormalities in structural connectivity (white matter tract integrity using diffusion tensor imaging), functional connectivity (resting state networks using resting state functional MRI) and perfusion (using arterial spin labelling perfusion MRI) in FTD. These techniques have the potential to improve the differential diagnosis of FTD from other disorders and to provide more informative imaging signatures of FTD syndromes.

Abstract The recognition of somatization process in cancer patients is a challenging and neglected area, for the extreme difficulty in differentiating and assessing the psycho(patho)logical components from those biologically determined and related to cancer and cancer treatment, as well as for the scarce usefulness of rigid categorical DSM criteria. However, several dimensions of somatization (and the interconnected concept of abnormal illness behaviour) have been shown to be diagnosable in cancer patients and to negatively influence coping and quality of life outcomes. ⋯ More research is also needed regarding the association of somatization with personality traits (e.g. type D distressed personality, alexithymia), developmental dimensions (e.g. attachment), and cultural issues (e.g. culturally mediated attributional styles to somatic symptoms). Also, the impact and effectiveness of specific therapeutic intervention in 'somatizing' cancer patients is necessary.

The behavioural aspects of somatic symptom disorders have received minimal research attention to date. The first section of this paper identifies key theoretical perspectives relevant to behavioural responses to illness. Specifically, the sociological concept of illness behaviour is offered as a general framework in which to consider the range of psychosocial factors associated with responses to perceived illness. ⋯ Additional insight is provided into two contemporary instruments which aim to measure overt behavioural aspects of illness more specifically. The third and final section of the paper makes recommendations for how future research may advance the understanding of state- versus trait-based characteristics of illness behaviour. Suggestions are made for how adaptive forms of behaviour (e.g. self-management, appropriate coping) may reduce the risk of developing a somatic symptom disorder or alternatively, minimizing the potentially negative psychosocial implications of such a presentation.

Somatic symptoms are common presentations in health settings. They can manifest as symptoms of another underlying mental disorder or be termed as medically unexplained. When they are medically unexplained they are invariably subsumed under the diagnostic categories of somatoform disorders. ⋯ It appears that no one measure fulfils the essential criteria of an ideal measure for somatic symptoms. The measures of somatic symptoms should also be culturally sensitive and serve diagnostic, prognostic and heuristic purposes. These aspects are highlighted in the review.

Psychological consequences of obesity: weight bias and body image in overweight and obese youth.
Over the past several decades, the prevalence of overweight and obesity in children has increased considerably. While it has been widely documented that childhood obesity is related to a variety of negative health consequences, and numerous campaigns have focused on increasing physical activity and healthy food choices in children, less research has focused on the negative psychological consequences of childhood obesity, namely body image disturbance. This article examines research on body image disturbance in overweight/obese children, comorbidity of psychological disorders and childhood overweight/obesity, and factors that contribute to body image disturbance in overweight and obese youths. Additionally, the authors present research pertaining to treatment and prevention of body image disturbance in overweight/obese youths and discuss potential future directions for research, prevention and advocacy.
