(α,non,and gusto). Deageustia, Fect, or Loss of taste, called also Apogeusia, Apogeusis. Dr. Cullen ranks this as a genus of disease, in the class locale*, and order dysesthesia. The causes are fever, or palsy, whence he forms two species: the first he calls organic, arising from some affection in the membrane of the tongue, by which relishing things, or those which have some taste, are prevented from coming in contact with the nerves; the second atoxic, arising from a weakness of the nerves, without any affection of the tongue. Sauvages thinks the cause of this disease to be either in the brain, in the tongue itself, or in the passage of the lingual nerves. He forms two species: first, febrilis, where a suppression of taste accompanies fevers, from the rough tongue; delirium, or coma: second, paralytica, when it accompanies a paralysis of the tongue or some comatous disorder. - Nosologia Methodica, vol. i. 751.
