Over the long term, epilepsy is clearly associated with cognitive impairment. This has been demonstrated functionally, using neuropsychological testing, and reinforced by structural studies showing progressive atrophy in patients with chronic epilepsy 1-3. The prevailing explanation for this, of course, has been the direct and cumulative effects of seizures on the brain. The basic science literature is chock full of studies showing impairment of neuronal function after seizures, both acutely and chronically. And for those of us who see patients, the progressive memory complaints and clear-cut decline in function seen in those with drug-resistant epilepsy — particularly temporal lobe …

Expression of long interspersed element-1 (L1) is upregulated in many human malignancies. L1 can introduce genomic instability via insertional mutagenesis and DNA double-strand breaks, both of which may promote cancer. Light exposure at night, a recently recognized carcinogen, is associated with an increased risk of cancer in shift workers. We report that melatonin receptor 1 inhibits mobilization of L1 in cultured cells through downregulation of L1 mRNA and ORF1 protein. The addition of melatonin receptor antagonists abolishes the MT1 effect on retrotransposition in a dose-dependent manner. Furthermore, melatonin-rich, but not melatonin-poor, human blood collected at different times during the circadian …
