Many things can trigger debilitating depression. Feelings of depression are caused by a chemical change that affects how the brain functions.
A normally functioning brain is a giant messaging system that controls everything from your heartbeat, to walking, to your emotions. The brain is made up of billions of nerve cells called neurons. These neurons send and receive messages from the rest of your body, using brain chemicals called neurotransmitters.
These brain chemicals—in varying amounts—are responsible for our emotional state. Depression happens when these chemical messages aren’t delivered correctly between brain cells, disrupting communication.
Think of a telephone: if your phone has a weak signal, you may not hear the person on the other end. Their communication is muted or unclear.
The good news is that there are many forms of treatment that can help you cope with depression, including medications that can strengthen weak signals by raising the levels of certain neurotransmitters, or by improving the neurons’ ability to process signals. This ensures that the brain’s vital messages are delivered—loud and clear.
If you notice that your son, daughter, your brother, sister, parents, a friend, are acting different, being isolated of all people, with sad eyes looking to nowhere, talk to them, show them your love and take them to a doctor.
You can save a life.
