There are many cause of depression. Depressive reaction, or "normal depression," occurs as a result of a particular event for example, when a family member dies.
Depressed moods can also be a side effect of medication, hormonal changes (such as before menstrual periods or after childbirth), or a physical illness, such as the flu or a viral infection.
Although the exact causes of major depression are unknown, researchers currently believe that both forms are caused by a malfunction in the brain chemical (these chemicals help monitor and regulate moods).
The elderly who suffer from depression are often misdiagnosed as having senile dementia which is incurable. This is unfortunate as depression is treatable and there is a high success rate once properly diagnosed.
You should consult a psychiatrist in order to be properly diagnosed if you have any of the above symptoms.
There are many therapies, both conventional and alternative, that are available for depression. Treatments may vary according to the cause of the depression and its severity. Conventional methods include psychotherapy, antidepressant drugs, and electroconvulsive therapy (ECT).
Electroconvulsive therapy (ECT) or electric shock treatment is still rather controversial but has been refined over the last 20 years. This form of therapy should only be considered once all other options have been explored.
Many alternative therapies are effective but should only ever be thought of as complementary to conventional medical treatments.
In addition to your conventional therapies you might want to investigate yoga and acupuncture both having had some success with other people suffering from depression.
Aromatherapy - Aromatherapy may ease mental fatigue and help with sleep. The essential oils that may benefit depression are basil, clary, jasmine, rose, and chamomile (Matricaria recutita).

When to seek further professional advice
NOTE: There is a distinct difference between feeling "depressed" and having a depressive illness. If you have low spirits for a while, don't be concerned. However, if you feel you can't lift yourself out of your misery, seek help.
