Purpose: Brain health is a dynamic state involving cognitive, emotional, and motor domains. Measuring brain health is a challenge owing to the uncertainty as to whether it is one or many constructs. This study aimed to contribute evidence for brain health as a unified construct by estimating the strength of relationships between and among patient-reported items related to the brain health construct in a population with brain vulnerability owing to HIV.

Design: Cross-sectional Structural Equation Modeling (SEM) of data from 824 older people living with HIV in Canada, participating in the Positive Brain Health Now study.
Method: SEM was used to link observed variables, including comorbidity, polypharmacy, anticholinergic and sedative burden, to cognitive ability and two latent constructs - physical frailty and perceived cognitive deficits (PCD).
Article Synopsis
- The study examined the short-term effects of an educational workshop paired with either an outdoor walking group or weekly reminders on older adults' outdoor walking and overall well-being.
- It involved a randomized controlled trial with 190 community-dwelling seniors, dividing them between a 10-week outdoor walk group and those receiving weekly reminders after an educational session.
- Results showed no significant difference in outdoor walking minutes between groups at various time points, although the outdoor walking group exhibited improvements in walking capacity after the initial phase.
Article Synopsis
- Researchers at McGill University created a small device called Heel2Toe™ that makes a sound to help people with Parkinson's improve their walking.
- In a study with 27 participants, those using the Heel2Toe™ sensor showed better walking results compared to those using a workbook.
- Most people using Heel2Toe™ reported being happy with the device, suggesting it could be a helpful tool for improving gait in Parkinson's patients.
