Dementia: Tactile Decline May Signal Early Cognitive Impairment

A new scientific review published in Biological Psychology highlights the potential role of touch-related sensory decline as an early warning sign for cognitive deterioration. The findings suggest that age-related impairments in tactile perception, including sensitivity to pressure, vibration, and object recognition, may predict cognitive challenges and even the progression toward dementia. The review outlines how changes in the brain’s sensory processing areas, especially the hippocampus, are tightly linked to both declining touch perception and memory, attention, and executive functioning.
