where there's a will, there's a way



Our central nervous system consists of a brain, a spinal cord, 31 pairs of spinal nerves, and 12 pairs of cranial nerves. There are roughly one hundred billion neurons (nerve cells) in the central nervous system. These neurons form a network which handles various tasks such as controlling mental functions, controlling physical functions and regulating activities of glands. A neuron is the fundamental element of the brain. One neuron can communicate with other neurons through electrical messages (around 100 milivolts with the duration of 1 milisecond) or through exchanging neuro-hormonal chemicals (such as dopamine, serotonin, norepinephrine ...).

When there exists a large number of unhealthy neurons in the brain, the communication links from one region to another region in the brain may become weak or totally paralyzed. Depending upon the location of unhealthy neurons, the symptoms can vary from “developmental delay” to “autism” or from “parkinson's disease” to “cerebral palsy”. So, in short, from a neuron's point of view, different mental illnesses are actually very similar to one another because of the existence of unhealthy neurons in the brain. However, the locations of these unhealthy neurons differentiate one kind of mental illness to the others.

Neurons become unhealthy when injury happens. Neurons can be injured due to chemical toxics, physical impact, emotional trauma, oxygen or blood deficiency, tumors, .etc. The injury to neurons can happen any time before birth, during birth, or after birth. Genes can be a factor for making the neuron injury more or less susceptible.
