Shortly after entrance, Levenson had a severe convulsion, with unconsciousness. The movements were mainly on the right side of the body, and there was a post-convulsive weakness of the right side for several days, followed by a slow recovery of strength.
The course of the disease—convulsions followed by improvement—is very characteristic of a paretic onset. The laboratory findings were in all respects confirmatory. It was rather striking that a permanent motor aphasia followed the convulsions in this case, since the seizures of paresis do not in the vast majority of cases leave permanent paralyses. The course of the disease continued to show convulsions, which would in each instance leave him at a lower terrace of capacity than had been before shown. The patient died four years after the onset of symptoms of a general asthenia. With the exception of the permanent motor aphasia, this case might be regarded as a fairly typical one of general paresis.
1. What is the general nature of speech disorder in paretic neurosyphilis? Speech disorder is, along with the pupillary changes, one of the most important clinical symptoms in paretic neurosyphilis. There are aphasic and articulatory disturbances. The aphasia that accompanies paretic seizures is of a transient nature as a rule. A case with such long-standing motor aphasia as shown by Levenson is not common. Paraphasia, with incorrect naming of objects, may last longer. The so-called “sticking” phenomenon is often observed.
Word-deafness is said to be rarer but is difficult to test on account of the patient’s dementia. Agrammatism (incapacity to form correct sentences) is sometimes observed. But the most characteristic disorder is in the syllabic composition of words. Syllables are left out (“medaltricity” for medical electricity), or fused (“exity”), or doubled (“electricicity”). Besides the central speech disorders of which the above are examples, there are disorders in articulation, which at first occur as a consequence of paretic seizures or in states of excitement, but later become permanent. These are divided into paretic and ataxic disturbances.
2. What is the structural basis of these forms of aphasia? It is believed that they are due to microscopic changes, not to coarse destructive lesions.
