A new study shows that walking can enhance connections within and between three critical brain networks, one of which is linked to Alzheimer’s disease. The research, involving older adults with normal cognitive function and those with mild cognitive impairment, showcased an improvement in memory recollection abilities after a 12-week walking exercise regimen. The brain activity observed was stronger and more synchronized post-exercise, providing hope for combating cognitive impairment and potentially delaying the onset of Alzheimer’s dementia.
Most antidepressants used for chronic pain are being prescribed with “insufficient” evidence of their effectiveness, scientists have warned.
Researchers have found a correlation between patients with rheumatoid arthritis and Parkinson’s disease. In their paper published in JAMA Neurology, researchers found a significantly higher risk of Parkinson’s disease (PD) in patients with rheumatoid arthritis (RA).
Researchers have delved into the brain’s grey and white matter, investigating the impacts of fibromyalgia. Using MRI, the team detected reduced grey matter volume in the pain-processing areas of fibromyalgia patients.
Neuroscientists have discovered how vitamin D deficiency impacts the development of neurons, contributing to disorders such as schizophrenia. These findings underscore the importance of vitamin D in the structural differentiation of dopaminergic neurons and suggest that maternal vitamin D deficiency might alter how early dopaminergic circuits form.
Finally this week, researchers have cracked the mystery behind how the Botulinum neurotoxin type-A, also known as Botox, infiltrates neurons.
