The Dark Side of the Neuroglia

The neuroglia gives rise to mitotically dysfunctional forms. It has ghastly potential for abnormal growth.

Glial cells (especially astrocytes, but also oligoden-drocytes and ependymocytes) can wreak havoc in the CNS. Excepting metastatic cancer, these intrinsic elements of the brain comprise the largest source (50-60%) of primary brain tumors.

The neuroglia is a central topic of neuropathology. Glial tumors are now confronted by remarkable advances in treatment, stemming from molecular biology, genetics, immunology, and other fields. Reactive changes of the various glial cells, especially increased numbers of astrocytes and their fibers and the swelling of oligodendrocytes, follow almost every type of brain disease or injury and, in addition to playing phagocytic and reparative role as described, provide key early indications of abnormality. These warning signs have mainly been noted postmortem. But they can be detected or inferred from modern brain imaging and during neurosurgical procedures on the brain. Someday, we may have some high-technology methods of detecting these subtle reactions before it is too late.

Breaking Bulimia

We have all been there: turning to the refrigerator if feeling lonely or bored or indulging in seconds or thirds if strained. But if you suffer from bulimia, the from time to time urge to overeat is more like an obsession.
