Disorders of the nervous system encompass broad categories of disease. It is impossible to review the clinical progress accomplished during the last year in a brief essay such as this. What follows are a few selected topics I have found to be unusually interesting, related to internal medicine, and liable to be of clinical importance to a general physician audience.
Toxic Pseudotumor Cerebri
Pseudotumor cerebri is characterized by headache, papilledema, and increased intracranial pressure, in the absence of an intracranial mass. Although the alternative term "benign intracranial hypertension" has also been used, because spontaneous recovery generally occurs, the process is not always benign; occasionally, visual acuity may be severely damaged.Pseudotumor cerebri has many presumed causes. In only a few of them, however, is the mechanism of increase in intracranial pressure obvious. There may be increased venous pressure with a disproportion in the rate of formation and absorption of CSF
