Causes of Depression
The cause of depression is unknown, but there are many theories based on research.
Most likely, depression is caused by a combination of genetic, biological, environmental, and psychological factors.
Depressive illnesses are disorders of the brain.
Longstanding theories about depression suggest that important neurotransmitters—chemicals that brain cells use to communicate—are out of balance in depression. But it has been difficult to prove this.
Brain-imaging technologies, such as magnetic resonance imaging (MRI), have shown that the brains of people who have depression look different than those of people without depression.
The parts of the brain involved in mood, thinking, sleep, appetite, and behavior appear different.
These images do not reveal why the depression has occurred. They also cannot be used to diagnose depression.
Some types of depression tend to run in families.
However, depression can occur in people without family histories of depression too.
Scientists are studying certain genes that may make some people more prone to depression. Some genetics research indicates that risk for depression results from the influence of several genes acting together with environmental or other factors.
In addition, trauma, loss of a loved one, a difficult relationship, or any stressful situation may trigger a depressive episode. Other depressive episodes may occur with or without an obvious trigger.

What is Anxiety AND Do You Experience it?
Do you feel anxious before a dental visit or starting something new? Have you gotten the jitters before speaking in front of a large group or sweaty palms when thinking about the future?
These are common reactions when faced with something that’s scary or unfamiliar and it doesn’t necessarily mean that anything is wrong.
However, some people suffer from a more severe form of anxiety that causes more serious physical symptoms.
To better understand if your anxious feelings could be a sign of an anxiety or panic disorder, let’s take a look at some of the symptoms:
If you feel your heart is racing and you can’t breathe correctly, this can be a symptom of anxiety that is severe enough for you to get professional help.
Some people have uncontrollable fears of things like crowded places, driving, or germs that cause complete avoidance of places or situations.
The consistent inability to concentrate can be a symptom of anxiety. This must be consistent behavior, and not just on those occasions when you lack sleep or are hungry, for instance.
Nervous behaviors, such as walking around the same area over and over again or twitching your fingers or toes repetitively, can be a symptom.
A feeling a doom or that something will happen to you, such as an accident, heart attack, or even death, can be symptoms of an anxiety disorder or panic disorder.
Numbness in your hands, fingers, toes, and legs or feeling like you can’t stand are also common symptoms.
If you find you have trouble swallowing or unusual dry mouth episodes, these may be indications of anxiety.
Fear of people around you and the desire to be alone are feelings that many anxiety sufferers face.
The inability to leave your home can be a symptom of a severe anxiety or panic disorder.
If your normal activities become overwhelming to you, you could be suffering from anxiety or a panic disorder.
