TCAs have been in use since the 1950s when imipramine (Tofranil) was shown to be effective for treating depression. TCAs primarily work by increasing the level of norepinephrine in the brain and to a lesser extent serotonin levels. Some TCAs also are antihistamines (block the action of histamine) or anticholinergic (block the action of acetylcholine, a neurotransmitter), and these additional actions allow for uses of TCAs other than for treating depression as well as additional side effects.
The signs of high-functioning anxiety and depression can get hidden within seemingly reasonable justifications. Even though one might be holding down a job, going to school, or in a healthy relationship, he or she experiences disruptions in life activities that may not be necessarily obvious. Some of these hidden disruptions can be seen in behaviors such as declining social invitations with the excuse that work has been busy or stressful, sleeping more or sleeping less, and an overreliance on coping mechanisms like excessive exercise, overeating, or overindulging in alcohol or illicit substances.
While this newly approved treatment offers hope as a fast acting and durable antidepressant option for patients who have not responded adequately to conventional SSRI or SNRI medications, it is important to be cautious. Many patients may seek out esketamine have not received trials with other evidence-based treatments including pharmacotherapy and psychotherapy or rTMS or ECT.
A very small number of people have had heart problems, epileptic fits or liver damage while taking antidepressants. It is believed that these were rare side effects of antidepressants. Various studies suggest that teenagers consider suicide more often when taking SSRIs or SSNRIs and also actually attempt to take their own lives more often. Teenagers should see their doctor or therapist more regularly at the beginning of treatment so that any risk of suicide can be identified early on.
Depression affects your brain, so drugs that work in your brain may prove beneficial. Common antidepressants may help ease your symptoms, but there are many other options as well. Each drug used to treat depression works by balancing certain chemicals in your brain called neurotransmitters. These drugs work in slightly different ways to ease your depression symptoms.
Bipolar II disorder is a significant variant of the bipolar disorders. (The usual form of bipolar disorder is referred to as bipolar I disorder.) Bipolar II disorder is a syndrome in which the affected person has repeated depressive episodes punctuated by hypomania (mini-highs). These euphoric states in bipolar II do not completely meet the criteria for the full manic episodes that occur in bipolar I.
Several types of psychotherapy (also called “talk therapy” or, in a less specific form, counseling) can help people with depression. Examples of evidence-based approaches specific to the treatment of depression include cognitive-behavioral therapy (CBT), interpersonal therapy (IPT), and problem-solving therapy. More information on psychotherapy is available on the NIMH website and in the NIMH publication Depression: What You Need to Know.
Self-help—For mild depression, or when moderate or severe depression begins to improve with other treatments, there are some things you can do on your own to help keep you feeling better. Regular exercise, eating well, managing stress, spending time with friends and family, spirituality, and monitoring your use of alcohol and other drugs can help keep depression from getting worse or coming back. Talking to your doctor, asking questions, and feeling in charge of your own health are also very important. Always talk to your doctor about what you’re doing on your own.
Bipolar Disorder: Formerly known as Manic Depression or Manic Depressive Disorder. While different from depression, bipolar disorder is often included in discussions around depressive disorders as it involves episodes of extreme lows similar to major depression. Someone with bipolar disorder, however, will swing in the opposite direction towards mania or extreme highs.
Mental health researchers agree that the causes of depression are much more complex than the chemical imbalance theory suggests. A growing body of research points to other physiological factors, including inflammation, elevated stress hormones, immune system suppression, abnormal activity in certain parts of the brain, nutritional deficiencies, and shrinking brain cells. And these are just the biological causes of depression. Social and psychological factors—such as loneliness, lack of exercise, poor diet, and low self-esteem—also play an enormous role.
Pregnancy or breast-feeding. A decision to use antidepressants during pregnancy and breast-feeding is based on the balance between risks and benefits. Overall, the risk of birth defects and other problems for babies of mothers who take antidepressants during pregnancy is low. Still, certain antidepressants, such as paroxetine (Paxil, Pexeva), may be discouraged during pregnancy. Work with your doctor to find the best way to manage your depression when you're expecting or planning on becoming pregnant.
MAOIs are older drugs that treat depression. They work by stopping the breakdown of norepinephrine, dopamine, and serotonin. They’re more difficult for people to take than most other antidepressants because they interact with prescription drugs, nonprescription drugs, and some foods. They also can’t be combined with stimulants or other antidepressants.
The key to living with depression is ensuring you’re receiving adequate treatment for it (usually most people benefit from both psychotherapy and medication), and that you are an active participant in your treatment plan on a daily basis. This requires a lot of effort and hard work for most people, but it can be done. Establishing new, healthier routines are important in many people’s management of this condition. Getting regular emotional support — for instance, through an online support group — can also be extremely beneficial.
The US Food and Drug Administration issued a safety information update in December 2011 concluding that it is unclear whether the use of SSRIs during pregnancy causes persistent pulmonary hypertension in the newborn. The FDA currently recommends that health care professionals and patients weigh the small potential risk of persistent pulmonary hypertension against the substantial risks of untreated depression during pregnancy. 
Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression, it affects how you feel, think and behave and can lead to a variety of emotional and physical problems. You may have trouble doing normal day-to-day activities, and sometimes you may feel as if life isn't worth living.
Antidepressants. A variety of antidepressants are prescribed for both anxiety and depression. Some of these also help alleviate nerve pain. The research most strongly supports the use of serotonin and norepinephrine reuptake inhibitors (SNRIs) or tricyclic antidepressants (TCAs) as double-duty drugs that can treat both psychiatric disorders and pain. The findings are more mixed about the ability of selective serotonin reuptake inhibitors (SSRIs) to alleviate pain.
Perimenopause, which is the time of life immediately before and after menopause, can last as long as 10 years. While perimenopause and menopause are normal stages of life, perimenopause increases the risk of depression during that time. Also, women who have had depression in the past are five times more likely to develop major depression during perimenopause.
Following a major life-changing event like a disabling illness, it is normal to feel a great deal of stress. Stress can build up over time and can lead to anxiety. Anxiety can be a response to a specific situation such as learning to walk all over again; it can also be more generalized such as not wanting to leave the house after being discharged from the hospital.
Clinical depression goes by many names, such as “the blues,” biological or clinical depression, and a major depressive episode. But all of these names refer to the same thing: feeling sad and depressed for weeks or months on end — not just a passing blue mood of a day or two. This feeling is most often accompanied by a sense of hopelessness, a lack of energy (or feeling “weighed down”), and taking little or no pleasure in things that once gave a person joy in the past.
The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Crisis lines aren’t only for people in crisis. You can call for information on local services or if you just need someone to talk to. If you are in distress, call 310-6789 (do not add 604, 778 or 250 before the number) 24 hours a day to connect to a BC crisis line, without a wait or busy signal. The crisis lines linked in through 310-6789 have received advanced training in mental health issues and services by members of the BC Partners for Mental Health and Addictions Information.
