The Acute and Chronic Effects of Lion's Mane Mushroom Supplementation on Cognitive Function, Stress and Mood in Young Adults: A Double-Blind, Parallel Groups, Pilot Study.

BACKGROUND: Given the bioactive properties and limited work to date, Hericium erinaceus (Lion's mane) shows promise in improving cognitive function and mood. However, much of the human research has concentrated on chronic supplementation in cognitively compromised cohorts. OBJECTIVE: The current pilot study investigated the acute and chronic (28-day) cognitive and mood-enhancing effects of Hericium erinaceus in a healthy, young adult cohort. DESIGN: This randomized, double-blind, placebo-controlled, parallel-groups design investigated the acute (60 min post dose) and chronic (28-day intervention) effects of 1.8 g Hericium erinaceus in 41 healthy adults aged 18-45 years. RESULTS: Analysis revealed that following a single dose of Hericium erinaceus, participants performed quicker on the Stroop task (p = 0.005) at 60 min post dose. A trend towards reduced subjective stress was observed following 28-day supplementation (p = 0.051). CONCLUSIONS: The findings tentatively suggest that Hericium erinaceus may improve speed of performance and reduce subjective stress in healthy, young adults. However, null and limited negative findings were also observed. Given the small sample size, these findings should be interpreted with caution. Further investigation in larger sample sizes is crucial, however the findings of this trial offer a promising avenue of interest.

A service evaluation of the multidisciplinary team approach to hypodontia.

Introduction Patients with hypodontia can be seen by a multidisciplinary team clinic (MDT) for treatment planning at the University Dental Hospital of Manchester (UDHM). The MDT consists of orthodontics, restorative dentistry and oral surgery colleagues.Aims and methods A retrospective case-note analysis was conducted on 558 hypodontia patients seen on Manchester Hypodontia Clinic (MHC) between 2016-2022 to assess service utilisation and treatment planning outcomes.Results The average age of patients attending the MHC was 16 (range 8-50). The distribution of mild, moderate and severe hypodontia in the sample was 28%, 37% and 35%, respectively. Most common treatments proposed were fixed appliances, extractions, implants and resin-bonded bridges. Out of 558 patients seen for consultation on the MHC, 365 (65%) were accepted for treatment. The average number of visits for treatment was 15.5 (range: 1-55). The average number of did not attend/was not brought appointments, patient cancellations and hospital cancellations were 0.8, 1.4 and 1.8, respectively.Conclusion Hypodontia patients referred to UDHM are triaged by consultants in orthodontics or restorative dentistry, and if MDT planning is required, they are booked onto the MHC. There are sufficient patients with complex cases of moderate and severe hypodontia to justify a regular MDT hypodontia clinic.
