Environmental effects on the central nervous system.

Abstract

The centrai nervous system (CNS) is designed to respond to the environment and is peculiarly vulnerable to many of the influences found in the environment. Utilizing an anatomical classification (cortex, cerebellum, peripheral nerves) major toxins and stresses are reviewed with selections from recent references. Selective vulnerability of certain areas to particular toxins is apparent at all levels of the CNS, although the amount of damage produced by any noxious agent depends on the age and genetic substrate of the subject. It is apparent that the effects of certain well known and long respected environmental toxins such as lead, mercury, etc., deserve continued surveillance. In addition, the overwhelming impact on the CNS of social damages such as trauma, alcohol, and tobacco cannot be ignored by environmentalists. The effect of the hospital and therapeutic environment has become apparent in view of increased awareness of iatrogenic disorders. The need for particular laboratory tests, for example, examination of CSF and nerve conduction toxicity studies, is suggested. Epidemics such as the recent solvent neuropathies suggest a need for continued animal studies that are chronic, as well as acute evaluations when predicting the potential toxic effects of industrial compounds.

Type B coxsackieviruses and central nervous system disorders: critical review of reported associations

“…Reactive microglia interact also with neurons via inflammatory cytokines (7). In neurons, received pro-inflammatory cytokines increase the amount of ROS that triggers the process of pyroptosis resulting in cell loss (8). Furthermore, pro-inflammatory cytokines produced by reactive microglia can initiate the activation of bystander specific cytotoxic T cells (9).…”
