“For two years, I would live in fear, developed anxiety, and basically felt like a social outcast. I thought people would be afraid of me, and I thought having a relationship with a girl would be very hard. I didn't want to tell anyone about my problem and I didn't want anyone to know.” Blake was diagnosed with epilepsy. Many of you might think, why this happens? why people with epilepsy loose control over their body through seizures? Well the answer lays in the mechanism of cell communication. Cells communicate in order to perform any activity or work in your system. When an epileptic seizure attack is performed Paracrine and Synaptic signaling in the nervous system in charge of cell communication isn’t working properly. To begin with Paracrine signaling works with a cell that secrets substances by vesicles, released to the extracellular fluid where substances are received by the other cells were the signal is been sent. The signal passes to the other cell by receptor proteins that work as guards that let or not the information (substance) get through the cell membrane of the receiver cell. In the other hand Synaptic signaling functions through electric signals released by neurotransmitters which also pass through the protein receptors guards located in the cell membrane stimulating the receiver cell. The signals mention before are the two main ways of communication of neurons in your nervous system. Also ionic channels are seen that they stimulate and they activate the cell to send electrical signals through central nervous system. Epilepsy is known as a brain disorder in which clusters of nerve cells or neurons in the brain sometimes transmit signals in an abnormal way. There have been diagnosed more than 30 types of seizures, which generally are divided into two types of such cases, focal seizures that affect only one side of the brain and generalized seizures that...
