Background: Gaining insight into the emotional consequences of disclosing amyloid Positron Emission Tomography (PET) results is essential for offering effective support to patients of varying cognitive status. This analysis aimed to examine variations in emotional distress levels following the disclosure of amyloid PET results among participants that are cognitively normal, with Mild Cognitive Impairment (MCI), or dementia.
Method: This investigation was a preliminary analysis of 55 participants, using 1-month follow-up call data of an ongoing brain imaging data repository study, obtaining baseline PET imaging on a subset of Alzheimer's Disease Research Center (ADRC) participants.

Background: In cognitively unimpaired (CU) older adults, the presence of a subjective cognitive decline (SCD) combined with evidence of abnormal b-amyloid (Ab) is proposed as stage 2 of Alzheimer's disease (AD) by the NIA-AA framework (Jack et al., 2018). However, the associations found between SCD and preclinical AD are inconsistent across studies, highlighting the importance of better understanding which specific SCD features are associated with either Ab or tau burden.

External rigid distraction is an established method for achieving subcranial Le Fort III advancement in severe syndromic craniosynostosis. Craniofacial surgeons commonly use halo-type devices for these corrections, as they allow for multiple vectors of pull and facilitate larger midfacial advancements. Although most complications related to their use involve pin displacement or infection, rare complications such as skull fractures have been reported.

Background: Psychological factors such as repetitive negative thinking, proneness to experience distress, and perceived stress are associated with increased risk of neurodegeneration and clinical dementia, whereas having a sense of life-purpose, self-reflection, and dispositional mindfulness may be protective. However, whether combinations of these risk and protective factors may inform distinct psychological profiles, which may be differential associated with age-related health outcomes is currently unknown.
Method: We included 742 middle-aged (mean age 51.
