The loss of the sense of touch; inability to feel tactile sensations; numbness or loss of tactile sensation.
From Greek 'a-' (without) plus 'pselaphesis' (touch, handling). The term comes from 'pselaphasthai' (to feel, touch) and the medical suffix '-ia' (condition).
Patients with severe neuropathy or spinal cord injuries experience apselaphesia—they can see their hand touching something hot but feel absolutely nothing, which is both fascinating and terrifying to neurologists!
