What Causes Depression?
Changes in our bodies because of aging sometimes trigger changes in our brains. For example, we may have fewer neurotransmitters than we used to. Neurotransmitters are some of the brain's chemical messengers. A lower supply of these messengers can lead to depression.
Sometimes depression appears for the first time in later life. Depression often goes hand in hand with other illnesses especially cancer, Parkinson's disease, heart disease, Alzheimer's disease, or stroke.
Depression can also appear after a very sad event like the death of a loved one. Difficult times such as losing your job, moving from your home, or losing your hearing can also trigger depression.
Some health problems–like a low thyroid hormone level-- can look like depression. Also, some medications can cause depression, and when the medication is stopped, the depression symptoms get better. This is why it is important to see your doctor for a complete physical checkup. That's the first step toward beating depression, no matter what the cause.
