SOMATOSENSORY AGNOSIAS Meaning and
Definition
-
Somatosensory agnosias refer to a group of cognitive disorders characterized by an inability or impairment to recognize and interpret sensory stimuli related to the body and its movements. The term "somatosensory" stems from the combination of the words "soma" (referring to the body) and "sensory" (pertaining to the senses).
Somatosensory agnosias typically result from damage or dysfunction in the somatosensory cortex or the association areas of the brain responsible for processing touch, proprioception (awareness of the body position in space), and kinesthesia (awareness of movement). These impairments can affect one or multiple sensory modalities, including touch, temperature perception, pressure, vibration, or pain.
Individuals with somatosensory agnosias may experience difficulty in recognizing common tactile stimuli, such as objects or textures, or differentiate between different body parts when not visually observed. This can manifest as an inability to identify objects solely by touch or perform complex tasks such as dressing or grooming. Moreover, patients may display diminished spatial and body awareness, resulting in trouble coordinating movements or gauging the position of their body in relation to the environment.
Somatosensory agnosias can occur as a result of various medical conditions, such as strokes, traumatic brain injuries, neurodegenerative diseases, or brain tumors. Treatment approaches may include rehabilitation, sensory re-education, and cognitive-behavioral interventions to aid in the recovery or adaptation of these sensory deficits.

Etymology of SOMATOSENSORY AGNOSIAS
The word "somatosensory" comes from the combination of two Greek words: "soma" meaning "body" and "aisthēsis" meaning "perception" or "sensation". "Agnosias", on the other hand, is derived from the Greek word "agnōsis", meaning "lack of knowledge" or "ignorance". When combining these two terms together, "somatosensory agnosias" refers to a group of neurological disorders characterized by a diminished or impaired perception of bodily sensations.
