Abstract

Circadian rhythm is a 24 hour or a day’s rhythmic oscillations with physiological and behavioural changes that is internally governed by the brain. This activity is generally anticipated by the internal and external cues from the environment. In circadian rhythm of our body is regulated by a transcriptional –translational Auto-regulatory loop which leads to the molecular oscillations of our “core clock genes” at a specific cellular level. In the many mammalian and animal models, the master pacemaker is in the hypothalamus at the suprachiasmatic nucleus (SCN) that can regulate downstream oscillations in the peripheral tissues of the brain. The core clock genes are self- sustained and cell autonomous not only on the pace maker but also on the other dissociated cultured cells and peripheral tissues. Here we can review the general mechanisms involved in the clock genes that is responsible for the circadian rhythmicity in epileptic syndromes and these findings can elucidate the cell specific expression of the clock genes in different syndromes. In the recent past there has been considerable amount of progress in elucidating the molecular and cellular mechanisms that is involved in understand the core clock gene expression and the circadian rhythms effects on epileptic syndromes. However, there is very little understanding on how these two mechanisms interact to cause a core clock genes disruptions plays an important role. Recent studies in several animal models have shown the effects of time of the day on the neurophysiology and path-physiology in the epileptic syndrome. Together, these evidences from the past suggest that there can be a common mechanism underlying the circadian rhythmicity and epileptogenesis mechanism.
