Depression is usually a neurotransmitter problem. Neurotransmitters are small molecules that are released from the end of one nerve. They move across a very tiny gap between the nerves called the synapse. On the other side of this gap, they bind to the other nerve causing it to fire. There are about 100 different neurotransmitters, dopamine is just one of them. When it is out of balance, one can have depression, fatigue, “brain fog”, low libido and/or attention deficit.
Other causes of depression include; hypothyroidism, B vitamin problems, and low Vitamin D. Hormones like estrogen, progesterone, and testosterone can also lead to depression.
Instead of making the diagnosis of depression and immediately writing a prescription, I like to look at the big picture. This helps me determine which of the above is the problem. Then I can treat with the appropriate therapy whether it be medication, vitamins, hormones or amino acids.
