However, researchers have also been looking into ketamine for treating depression. And results have been encouraging. Ketamine may have a “rapid onset” of antidepressant effect, meaning that it can help people feel better quickly. That boost may be temporary, lasting just a few days. And unlike antidepressants you can take once a day at home, ketamine must be injected or given by IV. Repeated treatments at a clinic might be necessary to help produce a long-lasting antidepressant effect, and psychiatrists and family doctors might not feel comfortable doing that. But here’s the promise: Quicker relief that helps people start living their lives again — getting out of that depressive funk sooner.

Schizophrenia is associated with an imbalance of dopamine (too much) and serotonin (poorly regulated) in certain areas of the brain. Finally, the depressive disorders appear to be associated with altered brain serotonin and norepinephrine systems. Both of these neurochemicals may be lower in depressed people. Please note that depression is "associated with" instead of "caused by" abnormalities of these neurochemicals because we really don't know whether low levels of neurochemicals in the brain cause depression or whether depression causes low levels of neurochemicals in the brain.

A type of mild to severe depression that typically sets in as the hours of daylight wane in the fall, seasonal affective disorder (SAD) afflicts as many as 6 percent of Americans. Women are particularly at risk, experiencing SAD four times more often than men, as are people who have a relative with depression. People who live far from the equator tend to experience SAD in greater numbers — 9 percent of Alaskans versus 1 percent of Floridians, according to the National Institute of Mental Health (NIMH).


For treatment with antidepressants to work, a careful diagnosis has to be made first. Experts believe that some people are prescribed antidepressants unnecessarily. The fact that significantly more people take antidepressants nowadays suggests that. These medications are sometimes already prescribed for milder cases, even though there is doubt about how well they work in mild depression.

Occasional feelings of sadness or depression are experienced by most people at some point in life. Feeling sad is a normal human response to difficult situations such as loss of a loved one, financial troubles, or problems at home. These feeling usually last for a few days. However, when these feelings turn into intense sadness, or a person feels helpless, worthless, and hopeless, and last for weeks or longer, it could be due to clinical depression. Depression is a common but serious mental illness that affects millions of Americans. The symptoms of depression interfere with daily life and cause significant pain to the patient and their loved ones. Although with proper treatment even severe symptoms of depression can get better, many people never seek treatment due to the societal stigma associated with mental illnesses.
SSRIs relieve symptoms by blocking the reabsorption, or reuptake, of serotonin by certain nerve cells in the brain. This leaves more serotonin available, which improves mood. SSRIs (citalopram, escitalopram, fluoxetine, paroxetine, and sertraline) generally produced fewer side effects when compared with tricyclic antidepressants.  However, common side effects include insomnia or sleepiness, sexual dysfunction, and weight gain. They are considered an effective treatment for all anxiety disorders, although the treatment of obsessive-compulsive disorder, or OCD, typically requires higher doses.
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.
While the majority of individuals with depression have a full remission of the disorder with effective treatment,only about a third (35.3%) of those suffering from severe depression seek treatment from a mental health professional.[2]  Too many people resist treatment because they believe depression isn't serious, that they can treat it themselves or that it is a personal weakness rather than a serious medical illness.
If the patient is taking MAOIs, he or she must avoid certain aged, fermented, or pickled foods, like many wines, processed meats, and cheeses. The patient should obtain a complete list of prohibited foods from the doctor and keep it available at all times. The other types of antidepressants require no food restrictions. It is also important to note that some over-the-counter cold and cough medicines can also cause problems when taken with MAOIs.
A mental health specialist is the type of professional best equipped to make a reliable diagnosis for this condition. These kinds of professionals include psychologists, psychiatrists, and clinical social workers. While a general practitioner or family doctor may be able to make an initial diagnosis, further followup and treatment should be done by a specialist for the best treatment results.
Several drugs of abuse can cause or exacerbate depression, whether in intoxication, withdrawal, and from chronic use. These include alcohol, sedatives (including prescription benzodiazepines), opioids (including prescription pain killers and illicit drugs such as heroin), stimulants (such as cocaine and amphetamines), hallucinogens, and inhalants.[17]
Of people diagnosed with major depressive disorder, who are treated and recover, at least half are likely to experience a recurrent episode sometime in their future. It may come soon after or not for many years. It may or may not be triggered by a life event. After several episodes of major depression, a psychiatrist may suggest long-term treatment. More
There are a range of ways to deal with depression, and often they are best used in conjunction with each other. The primary medical options are Cognitive Behavioural Therapy (CBT), antidepressant medication, and in some severe cases, Electroconvulsive Therapy (ECT). Education and coping strategies are also important when learning to manage your depression.

Beware of drug interactions. You should avoid drinking alcohol when taking SSRIs since it can lessen the effects of the medication. Dangerous drug interactions can occur when SSRIs are taken with antihistamines, found in many over-the-counter cold and allergy medicines and sleep aids, or with prescription painkillers. Always talk to your doctor or pharmacist before combining medications.

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.
It is important to communicate regularly with your doctor when you are taking an antidepressant, especially if you are prescribed any other medications. Keep track of your symptoms so that they can find the best medication for your depression, and also keep track of any side effects you experience. If you’re having trouble finding a medication that works, drug-genetic testing can help your doctor determine appropriate options. If you become pregnant or are breastfeeding, be sure to ask what medication is safest.
Medication may be right for you if depression is interfering with your ability to function in an important part of your life—work, school, or in your relationships, for example. However, many people use antidepressants when therapy, exercise, or self-help strategies would work just as well or better—minus the unpleasant side effects. Even if you decide to take medication, it’s a good idea to pursue therapy and lifestyle changes that can help you get to the bottom of your underlying issues and develop the tools to beat depression for good.

Talk therapy involves discussing your problems and how you feel with a trained therapist. Your therapist can help you detect patterns of thought or behavior that contribute to your depression. You may be given homework, such as tracking your moods or writing in journals. This will help you to continue your treatment outside of appointments. Your therapist can also teach you exercises to reduce stress and anxiety, and help you understand your illness.
The sensation that your heart has skipped a beat or suddenly started to race is known as palpitations. Although frightening, palpitations usually aren't a sign of something serious. Some home remedies may help: cut back on caffeine and alcohol, eat regularly to avoid low blood sugar, drink plenty of fluids to avoid dehydration, and practice meditation or relaxation exercises.
Depression generally takes one of two major forms. Unipolar depression is what most people mean when they talk about depression: an unremitting state of sadness, apathy, or hopelessness, and loss of energy. It is sometimes called major depression. Bipolar depression, or bipolar disorder, is a condition marked by periods of depression and periods of high-energy mania; people swing between the two poles of mood states, sometimes over the course of days, sometimes over years, often with stable periods in between. 
MAOIs also impair the ability to break down tyramine, a substance found in aged cheese, wines, most nuts, chocolate, certain processed meats, and some other foods. Tyramine, like norepinephrine, can elevate blood pressure. Therefore, the consumption of tyramine-containing foods by a patient taking an MAOI drug can cause elevated blood levels of tyramine and dangerously high blood pressure. In addition, MAOIs can interact with over-the-counter cold and cough medications to cause dangerously high blood pressure. The reason for this is that these cold and cough medications often contain drugs that likewise can increase blood pressure. Because of these potentially serious drug and food interactions, MAOIs are usually only prescribed for people who are thought to be willing and able to manage the many dietary restrictions required by these medications and after other treatment options have failed.
A type of mild to severe depression that typically sets in as the hours of daylight wane in the fall, seasonal affective disorder (SAD) afflicts as many as 6 percent of Americans. Women are particularly at risk, experiencing SAD four times more often than men, as are people who have a relative with depression. People who live far from the equator tend to experience SAD in greater numbers — 9 percent of Alaskans versus 1 percent of Floridians, according to the National Institute of Mental Health (NIMH).
Depressive signs and symptoms not only include negative thoughts, moods, and behaviors but also by specific changes in bodily functions (for example, excessive crying spells, body aches, low energy or libido, as well as problems with eating, weight, or sleeping). Neurovegetative signs are the changes in functioning associated with clinical depression. This means that the nervous system changes in the brain are thought to cause many physical symptoms that result in a decreased or increased activity level and other problems with functioning.
While you can’t force yourself to have fun or experience pleasure, you can push yourself to do things, even when you don’t feel like it. You might be surprised at how much better you feel once you’re out in the world. Even if your depression doesn’t lift immediately, you’ll gradually feel more upbeat and energetic as you make time for fun activities.
By working with a therapist or thinking strategically about the tactics you want to try, you can integrate them and execute several at once. For example, therapist Asta Klimaite often asks her clients to incrementally increase their exercise by using different methods and routes to reach her office. Her tactic also helps them develop a sense of accomplishing simple goals. They start by taking a different route to her office and using whatever mode of transportation they like. She then challenges them to ride a bike or walk to her office. Before they even start therapy, they are already working on their mental health.
When in the depressed cycle, the person can experience any or all of the symptoms of a depressive condition. When in the manic cycle, any or all of the symptoms listed later in this article under mania may be experienced. Mania often affects thinking, judgment, and social behavior in ways that cause serious problems and embarrassment. For example, indiscriminate or otherwise unsafe sexual practices or unwise business or financial decisions may be made when an individual is in a manic phase.
Another type of depression is related to changes in the length of days or seasonality. This type of depression is called Seasonal affective disorder (SAD). People with SAD suffer the symptoms of a Major Depressive Disorder only during a specific time of year, usually winter. This appears to be related to the shorter days of winter, and the lack of sunlight in many parts of the country.
Selegiline inhibits MAOb at lower doses and both forms at higher doses. Because it does not inhibit MAOa, it does not require dietary restrictions at lower doses. Lower doses of oral selegiline (Eldepryl) appear to lack antidepressant properties and are usually prescribed to treat Parkinson disease. Higher doses are used to treat major depressive disorder, and the selegiline transdermal patch is FDA approved for this indication. Selegiline is sometimes used off-label to treat attention-deficit/hyperactivity disorder.
Recovery from a depressive episode takes time as well as a desire and willingness for change. You can start by talking to someone — anyone — about your feelings, and finding some immediate emotional support through the sharing. Many people start their journey of recovery off by going to see their family physician for an initial diagnosis. Such a professional can also help connect you with referrals or encouragement to continue your treatment with a mental health specialist.
Serotonin syndrome: Serotonin syndrome is a serious medical condition that can occur when medications that alter the concentration of serotonin in the brain are taken together. Symptoms of serotonin syndrome may include anxiety, restlessness, sweating, muscle spasms, shaking, fever, rapid heartbeat, vomiting, and diarrhea. Examples of medications that can cause serotonin syndrome include antidepressants, some pain relievers such as meperidine (Demerol) or tramadol (Ultram), St. John's wort, medicines used to treat migraine headaches called triptans, and some street drugs such as cocaine.
In general, the severe depressive illnesses, particularly those that are recurrent, will require antidepressant medications, phototherapy for winter seasonal depression (or ECT or TMS in severe cases) along with psychotherapy for the best outcome. If a person suffers one major depressive episode, he or she has up to about a 75% chance of a second episode. If the individual suffers two major depressive episodes, the chance of a third episode is about 80%. If the person suffers three episodes, the likelihood of a fourth episode is 90%-95%. Therefore, after a first depressive episode, it may make sense for the patient to come off medication gradually. However, after a second and certainly after a third episode, most clinicians will have a patient remain on a maintenance dosage of the medication for an extended period of years, if not permanently.
Life is full of ups and downs, but when you feel sad, empty, or hopeless most of the time for at least 2 weeks or those feelings keep you from your regular activities, you may have depression. Depression is a serious mental health condition. In the past year, women were almost twice as likely as men to have symptoms of depression.1 Depression is not a normal part of being a woman. Most women, even those with the most severe depression, can get better with treatment.
