Physical Findings

Forty cases of disease of the central nervous system, characterized by several episodes and disseminated lesions, with onset in childhood and clinically typical of multiple sclerosis, were studied. The disease as it occurs in children does not appear to differ clinically from the disease as observed in adults, in respect to mode of onset, symptoms, physical findings, and changes in the spinal fluid. In the Mayo Clinic series, however, almost twice as many girls as boys were affected. A pediatrician confronted with a child showing evidence of scattered neurologic deficits that remit, particularly a disturbance of vision and co-ordination, should consider the possibility of multiple sclerosis.

The acetic anhydride test was introduced in 1923 by Boltz, who regarded a positive result as diagnostic of syphilis of the central nervous system. The technique of the test is simplicity itself, and is as follows: Place 1 c.c. of spinal fluid in a small test-tube. Add 0.3 c.c. of acetic anhydride drop by drop; shake. Add 0.8 c.c. concentrated sulphuric acid drop by drop; shake. After five minutes examine the colour of the fluid against a white background. A lilac or blue-pink coloration is positive.

The Many

For some time past there has been an increasing use of laboratory methods in the diagnosis of mental disorders. The following aims at offering further proof of the undoubted value of this method of approach in such cases. There seems, however, to be a growing tendency, not devoid of danger, to ascribe diagnostic specificity to one or other of the many tests in use for such examinations. Although it is undoubtedly true that an exhaustive analysis of a spinal fluid may in many cases lead to a correct diagnosis of the clinical condition of the patient from whom the specimen has been taken, it only requires a study of the literature to show that none of the reactions or group of reactions obtained from the spinal fluid can be regarded as pathognomonic of any disease of the central nervous system.

Wassermann Reaction

Whilst it is an undisputed fact that under certain clinical and experimental conditions various antibodies (antitoxins, agglutinins, bacterio- and hæmolysins, complement-fixing antibodies) can be demonstrated in the cerebrospinal fluid, there is a divergency of opinion about their origin. Whereas some authors (Dujardin and Dumont, Ramon, Descombey and Bilal, Neufeld and Szyle, Nélis) ascribe their presence in the cerebro-spinal fluid to their passage from the blood through a damaged blood-cerebro-spinal fluid barrier, other investigators (Mutermilch, liiert, Grabow and Plaut, Friedemann and Elkeles) believe that the central nervous system or its membranes are able to produce antibodies on their own upon contact with an antigen. In the case of the Wassermann antibody in the cerebro-spinal fluid the question of its origin is of particular interest, because of the occasional occurrence of cases which show a positive Wassermann reaction in the cerebro-spinal fluid and a negative or weaker reaction in the blood. This divergence between blood and cerebro-spinal fluid is often quoted as an example of the independence of the cerebro-spinal fluid antibody.
