#sensory disorder

• Ageusia — A total loss of the sense of taste, caused by lesions of the lingual mucosa, the afferent nerve pathways (facial, glossopharyngeal nerve), or the gustatory centers in the cerebral cortex. It can be congenital, but it is most frequently an acquired symptom following trauma, respiratory infections, or drug treatments.
• Alloesthesia — A neurological disorder of sensory perception where a stimulus applied to a specific part of the body is structurally felt on the opposite side or in a completely different location than the actual one; this cortical or radicular dysfunction affects the correct localization of tactile or painful sensations.
• Anomalesia — A rare sensory perception disorder characterized by a partial inability or congenital weakening of tactile and thermal sensitivity, often manifested through difficulties in correctly locating or differentiating physical stimuli applied to the skin. This structural deficit in innervation or central somatosensory processing is studied in clinical neurology in close connection with focal cortical lesions in the parietal lobe.
