Cholinergic modulation of disorder-relevant human defensive behaviour in generalised anxiety disorder.

Drugs that are clinically effective against anxiety disorders modulate the innate defensive behaviour of rodents, suggesting these illnesses reflect altered functioning in brain systems that process threat. This hypothesis is supported in humans by the discovery that the intensity of threat-avoidance behaviour is altered by the benzodiazepine anxiolytic lorazepam. However, these studies used healthy human participants, raising questions as to their validity in anxiety disorder patients, as well as their generalisability beyond GABAergic benzodiazepine drugs.

Cholinergic Modulation of Disorder-Relevant Neural Circuits in Generalized Anxiety Disorder.

Background: Generalized anxiety disorder is associated with hyperactivity in the amygdala-prefrontal networks, and normalization of this aberrant function is thought to be critical for successful treatment. Preclinical evidence implicates cholinergic neurotransmission in the function of these systems and suggests that cholinergic modulation may have anxiolytic effects. However, the effects of cholinergic modulators on the function of anxiety-related networks in humans have not been investigated.

Development of EASY-Care, for brief standardized assessment of the health and care needs of older people; with latest information about cross-national acceptability.

Introduction: The EASY-Care system has been developed in the past 20 years in the United States and Europe as a brief standardized method for assessing the perceptions of older people about their health and care needs and priorities for a service response. More recently, it has been adapted and tested for use in poor, middle-income, and rich countries across the world. In this article we review its development and report the latest data for cross-cultural acceptability to older people and their clinicians in 6 countries across 4 continents.
