Scientists are conducting experiments to see if targeting the enteric nervous system with a compound can inhibit the aggregation of alpha-synuclein and slow the progression of Parkinson's disease.
Lewy body disorders, including Parkinson's disease and Lewy body dementia, comprise of two distinct subtypes. One subtype originates in the peripheral nervous system (PNS) of the gut and spreads to the brain. The other originates in the brain, or enters the brain via the olfactory system, before spreading to the brainstem and PNS.
Gait disorders and slowed walking speeds may be useful indicators of future cognitive decline.
A new, non-invasive brain stimulation treatment shows promise in enhancing memories and cognitive function in those with Alzheimer's disease. Transcranial electromagnetic treatment (TEMT) increases functional connectivity within the cingulate cortex. TEMT is also able to penetrate the brain to break up amyloid-beta and tau deposits, slowing the progression of Alzheimer's disease.
A significant association has been discovered between migraine diagnoses and dementia in women.
Moral emotions are significantly more impaired than emotions without moral content in those with frontotemporal dementia (FTD). By contrast, those with Alzheimer's disease exhibit similar performance in both moral and extra-moral emotions as healthy subjects. The findings provide a novel biomarker for the diagnosis of FTD.
A newly developed audio-to-tactile sensory substitution device provides immediate and robust improvements in speech recognition without prior training for those with hearing impairments.
