The ADHD Assessment Quality Assurance Standard for Children and Teenagers (CAAQAS).
Neuropsychiatr Dis Treat
December 2024
Around 5% of the children and teenagers worldwide are affected by Attention-Deficit/Hyperactivity Disorder [ADHD], making it a major public health concern. Recently, demand for assessments has substantially increased, putting strain on healthcare and waiting lists. There is concern that pressure to clear service bottlenecks is leading to variable quality and reliability of ADHD assessments in this population.
View Article and Find Full Text PDFDebate continues about the nature of the Cretaceous-Paleogene (K-Pg) mass extinction event. An abrupt crisis triggered by a bolide impact contrasts with ideas of a more gradual extinction involving flood volcanism or climatic changes. Evidence from high latitudes has also been used to suggest that the severity of the extinction decreased from low latitudes towards the poles.

Aims: This study aimed to establish views on training and working in psychiatry amongst preclinical medical students at a South London Medical School and amongst a general public sample.
Methods: A semi-structured online questionnaire was used to survey medical students, with a similar paper questionnaire being used to survey members of the public in a general practice waiting room using a convenience sampling method.
Article Synopsis
- The geological records from Seymour Island reveal vital clues about the evolutionary history of modern polar marine species, specifically showing that 38 Southern Ocean molluscan genera can trace back origins to this area.
- The study observes a major shift in molluscan diversity across the Cretaceous-Paleogene boundary, with a surge in gastropod diversity driven by a significant radiative event in the Neogastropoda clade linked to warming temperatures.
- The expansion of neogastropods in early Paleogene Antarctica suggests that the region played a more complex role in evolutionary dynamics, challenging the notion that it was merely an evolutionary refuge during climate changes.
Article Synopsis
- * Unlike older formations, this community is characterized by infaunal bivalves and decapods, rather than the sessile suspension feeders commonly seen in modern Antarctic waters.
- * The modern Antarctic marine community's archaic retrograde traits may have developed more recently due to increased cooling and isolation of the continent, which led to the loss of shallow shelf habitats.
