3. What is the relation of the early symptoms of this case to the so-called preparesis of Dana? The case might well have been an example of Dana’s preparesis. For a discussion of this, see Case of William Twist (13).

4. What is the classical differential diagnosis between paretic neurosyphilis and neurasthenia? The testing of the blood by the W. R. is unconditionally necessary. If the W. R. is negative, the diagnosis of paretic neurosyphilis is extremely improbable. (It must be borne in mind that a number of cases of paretic neurosyphilis have been shown to have a negative W. R. in the serum, and receive a proper diagnosis only after spinal fluid examination.) Next to the serum W. R. stand the pupillary and aphasic symptoms. In the presence of Argyll-Robertson pupil or even a slight speech defect, the diagnosis of neurasthenia must certainly be made with caution if at all. Kraepelin remarks: The sudden occurrence of neurasthenic disorders in a male of middle age without any evident cause therefor is always suspicious. Yet it must be emphasized that a complaint of occasional dizziness, slight speech defect, tremor of tongue, and a moderate increase of tendon reflexes do not possess any marked diagnostic significance. Clear insight and understanding of the nature of the disease phenomena, a persistent search for recovery, reasonableness in conversation, progressive improvement under appropriate treatment, speak for neurasthenia.
