senselacking

Senselacking is a colloquial, non-medical term used to describe reduced or absent sensation in one or more sensory modalities, such as touch, temperature, proprioception, taste, smell, vision, or hearing. It is not a formal diagnosis, but a descriptor used in informal discussion and some clinical contexts to indicate a subjective loss of sensation.

In medical contexts, senselacking may correspond to established terms like hypoesthesia (reduced touch), anesthesia (absent sensation), ageusia (loss of taste), or anosmia (loss of smell). It is typically based on patient reports and may be explored with objective tests such as quantitative sensory testing, nerve conduction studies, audiometry, or dermatome mapping.

Common causes include peripheral neuropathy, spinal cord injury, stroke, multiple sclerosis, diabetes, trauma, infection, or congenital sensory disorders. It can be focal (limited area) or diffuse and may be accompanied by pain, tingling, or changes in thermal sensitivity.

Technology and research areas address senselacking by using sensory substitution or augmentation, such as haptic feedback, neural prosthetics, or multisensory integration training. In daily life, individuals may rely on visual or auditory cues to compensate, and designers strive for accessible products that account for reduced sensation.

The term remains informal and heterogeneous in usage. Clinicians prefer standard terminology when documenting conditions, while researchers discuss senselacking as a starting point for exploring sensory restoration and neural plasticity.
