They are bewildering because in contrast to any other psychiatric disorder, patients often value at least some aspects of their disorder (e.g. being able to restrict their food intake, extreme exercise) and are reluctant to change. These disorders are frigh...

Functional neuroimaging in psychiatry

Functional neuroimaging has rapidly developed as a powerful tool in cognitive neuroscience and, in recent years, has seen widespread application in psychiatry. Although, such studies have produced evidence for abnormal patterns of brain response in association with some pathological conditions, the core pathophysiologies remain unresolved. Although, imaging techniques provide an unprecedented o...

Recent findings and newer paradigms of neuroimaging research in geriatric psychiatry.

Over the past several decades, there has been a significant increase in the population of older adults and associated mental health problems throughout the world. For older adults, mental health problems such as dementia, depression, psychosis, and anxiety disorders can be debilitating and reduce the overall health and quality of life. Moreover, as most of the geriatric psychiatric disorders ar...

Functional neuroimaging in child psychiatry.

Functional neuroimaging in child psychiatry presents unique scientific, ethical, and technical challenges. The study of childhood disorders presupposes knowledge of neurodevelopment and brain maturation. However, much of human brain science is based on inferences from animal work and indirect neurochemical measures from body fluids. Neuroimaging can examine brain development directly in humans....
