====== Thermoanaesthesia ====== loss or absence of the ability to distinguish between heat and cold by touch. ===== Case report ===== A 53-year-old female patient presenting with impaired [[Thermoception]] on the left half of her body, from the [[neck]] down, following a small [[infarction]] of the right midlateral [[medulla]]. The chronological changes in the patient's introspection regarding impairment of [[thermoception]] and the results of detailed somatosensory tests, including thermal sense, are shown in this report. Thorough [[somatosensory]] tests, personal descriptions of symptoms, and electrophysiological quantification of similar cases are needed to improve our understanding of the neurological separation of the sensations of [[pain]] and [[temperature]] at the medullary level ((Hanada K, Yokoi K, Kashida N, Shimomura R, Murata D, Hirayama K. Midlateral [[medullary infarction]] presenting with isolated [[thermoanaesthesia]]: a case report. BMC Neurol. 2022 Jul 19;22(1):268. doi: 10.1186/s12883-022-02796-x. PMID: 35854223.)).
