“…A Philips 3T scanner was used at Hammersmith Hospital to collect T1‐weighted images with the following parameters: 208 x 208 matrix, TR = 9.60 ms, TE = 4.60 ms, and 8° flip angle. A subset of images exhibited motion artifact and were identified and excluded based on a structural covariance method that quantified how dissimilar an image was from every other image in the sample (>2 SD; n = 4 MUSC sample; n = 3 Hammersmith sample) …”

Objectives/Hypothesis There is a growing need to understand the underlying mechanisms of age‐related olfactory dysfunction with the increasing proportion of older adults over the next 20 years. Despite the importance of olfactory cleft (OC) volumes on odorant deposition and olfactory function, little is known about age‐related changes to OC volume. The goal of this study was to use automated techniques in a cross‐sectional design to investigate the extent to which OC volumes vary with age and determine the spatial specificity of any age‐related effects. Study Design Retrospective cross‐sectional study. Methods Deformation‐based morphometry was utilized to measure OC and sinus volumes in two independent samples of 101 (Medical University of South Carolina [MUSC] sample) and 95 (Hammersmith sample) healthy adults who underwent T1‐weighted magnetic resonance imaging, with the Hammersmith sample serving as a replication sample. Results The mean age of the MUSC and Hammersmith samples were 54.9 ± 17.0 years and 52.1 years ± 15.7 years, respectively. In both samples, there was a significant positive association between age and OC volume that occurred at a constant rate across the lifespan (Cohen's f2 of 0.065 in the MUSC sample and 0.110 in the Hammersmith sample). Age‐associated OC volume increases occurred in conjunction with decreases in sinus volumes as well as increases in non‐OC nasal cavity volumes. Conclusions In this cross‐sectional study, there is an increase in OC volume with increasing age that occurs in the context of broad age‐associated differences in sinonasal anatomy. Future studies should investigate the impact of age‐associated differences in intranasal anatomy on nasal airflow, odorant deposition, and olfactory function.

BPPBilateral perisylvian polymicrogyria WDS Worster-Drought syndrome AIM We aimed to systematically review the speech production, language, and oral function phenotype of bilateral perisylvian polymicrogyria (BPP), and examine the correlation between the topography of polymicrogyria and the severity of speech, language, and oral functional impairment.METHOD A systematic search of MEDLINE, Embase, and PubMed databases was completed on 26th October 2017 using Medical Subject Heading terms synonymous with BPP and speech, language, or oral motor impairment. In total, 2411 papers were identified and 48 met inclusion criteria.RESULTS Expressive and receptive language impairment and oral structural and functional deficits are frequent in BPP. Expressive deficits are frequently more severe than receptive. Only one study used formal assessments to demonstrate the presence of speech disorder, namely dysarthria. Seven studies reported an association between diffuse BPP and more severe language impairment.INTERPRETATION Findings confirmed that language deficits are common in BPP, though assessment of the specific speech phenotype is limited. The paucity of high quality studies detailing the specific communication phenotype of BPP highlights the need for further investigation. Improving understanding of this phenotype will inform the development of targeted therapies and lead to better long-term outcomes.
