Sleep and Depression are closely related to each other. We know that a loss of sleep effects can affect ones mood and when this occurs long enough it can turn into Depression. Post-Menopausal women who are overweight and symptoms of depression should be screened for Obstructive Sleep Apnea. In a government study that examined 10,000 adults, they found that the more a person snorted, gasped for air or stopped breathing, the more likely they were to have symptoms of depression. Sleep disorders can also be caused from Depression. Often Insomnia is the first symptom that a depressive patient presents with. Over time, these patients may go on to develop depression. Generally, the treatment for depression does not control the Insomnia. It requires its own treatment.
