This 2022 systematic review and meta-analysis pooled data from 223 studies to see if voluntary slow breathing (VSB) changes heart rate variability that reflects parasympathetic (vagal) control of the heart. The authors found that VSB increased vagally-mediated heart rate variability during breathing sessions, right after a single session, and after…
Chronic Fatigue Syndrome (CFS) is defined as more than 6 months of new, disabling physical and mental tiredness that is not relieved by rest. Up to about 85% of people with CFS report cognitive problems called “brain fog,” described as slow thinking, trouble focusing, confusion, forgetfulness, or a hazy mind.…
This clinical trial tested one session of deep and slow breathing (DSB) in 47 adults (22 older, 25 younger). After the single DSB session, high-frequency (HF) heart rate variability increased and self-reported state anxiety went down in both age groups. The rise in HF power was significantly larger in older…
In a randomized, double-blind, placebo-controlled trial, people took supplements containing the mushroom Hericium erinaceus for 12 weeks. The researchers gave three mental tests and found that only the Mini-Mental State Examination (MMSE) showed a statistically significant improvement and less decline in the group taking the mushroom. The authors say compounds…
The results suggested that CFS is associated with IFOF WM deficits which continue to deteriorate at an abnormal rate. J. Magn. Reson. Imaging 2016;44:1301-1311.
This retrospective study asked 85 people with ADHD and/or autism who had been prescribed weighted blankets about their sleep and daily routines. The participants reported that the blankets helped them fall asleep, sleep through the night, and relax during the day. Many also said their morning and evening routines (going…
Researchers scanned the brains of 371 adolescents and young adults (average age 17.1) while they did a visuospatial working memory task. They found that anxiety changed the link between how severe a person’s ADHD symptoms were and brain activity. Specifically, higher anxiety was linked with lower activity in the cerebellum…
ADHD is a lifelong brain-development condition that makes it hard to keep attention, plan and organize, control impulses, be still, or manage emotions. Some people are diagnosed as children, while others first seek diagnosis as adults when life becomes less structured or family members recognize the pattern. Many other problems…
