Below is a more detailed description of the types of depression people struggle with:
Major Depressive Disorder (MDD)
Also known as clinical depression, this is the most common type. MDD can occur in episodes that last at least two weeks or much longer – months or even years, and it is frequently accompanied by anxiety. Fortunately, TMS therapy is able to help alleviate both anxiety and depression.
Persistent Depressive Disorder (PDD)
PDD is also called dysthymia or chronic depression. Rather than being episodic in nature, it is continuous but usually less severe than episodes of MDD. However, these two types are not always distinguishable. Many people suffer with an overall low mood and lack of interest in activities that were once enjoyed. Many tasks, including daily work assignments, can become difficult to perform and complete. Since PDD and MDD can be difficult to distinguish, some people previously diagnosed with PDD can later on be diagnosed with MDD. It is important to check with your doctor, or to seek a second opinion, to determine the best course of treatment for your type of depression.
For years, this was more commonly known as manic depression or manic depressive illness. That’s because it consists of two mood states, mania and depression. Symptoms are typically quite severe in both categories, and is not to be confused with typical mood swings many people experience. Bipolar disorder includes extreme lows with difficulty or inability to function, as well as extreme highs with racing thoughts or high-risk behavior. There are different forms of Bipolar Disorder:
Bipolar I—includes manic or mixed states (depression and mania together) lasting at least 7 days, and depressive episodes that occur for 2 weeks or more.
Bipolar II—consists of what is called hypomania, episodes that are not as extreme as full-blown mania. Also includes depressive episodes
Bipolar Disorder Not Otherwise Specified (BP-NOS)–symptoms include mania and depression but are not as extreme or do not meet the criteria for Bipolar I or II
Cyclothymic Disorder—episodes of hypomania and mild depression that last for at least two years, with milder symptoms than those listed above
Rapid-Cycling Bipolar Disorder—typically seen in people who have earlier onset of bipolar disorder, sometimes mid to late teens, with episodes that quickly switch between mania and depression or both at the same time.
Much more is being discovered with regard to postpartum depression. It affects between 10 and 15% of new mothers, after they give birth, and can be quite severe. Sometimes this problem is compounded by the fact that they were on antidepressants and needed to quit taking them before getting pregnant. Prior depression combined with the hormonal changes during and after pregnancy, the stress involved, and the lack of sleep create a difficult scenario. This is one of the great benefits of TMS. If a woman already struggles with depression and wishes to have a child, she can undergo TMS therapy to ease or alleviate her depression before, during, and after pregnancy, including through breastfeeding when medications are not safe.
Also called depressive psychosis, it combines a major depressive episode (MDD or bipolar) with psychotic symptoms. The psychotic symptoms consist of delusions and/or hallucinations. Delusions include themes such as guilt, shame, punishment, and low self-esteem. The hallucinations are typically auditory, visual, olfactory, or tactile (involve the sense of touch).
Seasonal Affective Disorder (SAD)
SAD typically occurs during the winter months when there is less sunlight. A less common form of SAD starts in late spring or early summer and dissipates in the fall. People are affected during this same time of the year, each year. The causes of this are still uncertain.
