There is no precise categorization for stages of depression because depression has numerous causes and manifests and progresses differently among different people. What most experts attempt to discern are the signs and symptoms that might be apparent at the onset of depression. The National Institute of Mental Health (NIMH) advises that it is important to identify these signs to seek help as early as possible because depression can become a serious illness.
Definition
There are varying types and manifestations of depression. The NIMH differentiates a bout of sadness lasting days from a state of depression in which the sadness begins to interfere with daily life and normal functioning. Depression is a mental illness that can lead to long-term grief for the person suffering from it and also affect well as family and friends.
Causes
Depression might or might not have an identifiable cause. According to the NIMH, depression likely results from a combination of genetic, biochemical, environmental and psychological factors. If a cause is identified at the outset, a treatment plan can be developed that ideally will help prevent the depression from worsening. Treating depression after it has progressed might require different methods than if it is identified early.
Initial Stage
Mental Health Matters and the American Psychological Association (APA) interpret the first stage of depression as usually beginning at around two weeks after onset. In people without depression, an initial event can trigger sadness, but after two weeks a person typically begins to gain new perspective on the situation and an improvement in mood occurs. With depression, the sadness remains or the grief becomes greater, hindering the person's ability to function at normal levels.
Symptoms
Because there are various causes of depression, its early symptoms also can vary. The NIMH lists symptoms such as persistent sad or anxious feels, and feelings of hopelessness and worthlessness. In the early stage, signs of depression include a loss of interest in activities one normally enjoys and a decrease in energy. Eating habits also can change, and other symptoms can include muscle aches and pains, and persistent headaches and stomachaches.
Treatment
Treatment for depression should be sought as early as possible. A visit to the physician should be first, as she can rule out if there are any other factors that are contributing to a change in health before recommending therapy for a depression. The earlier that treatment can begin, the more effective it is and the greater the likelihood that recurrence can be prevented, emphasizes the NIMH.
