Serotonin and norepinephrine reuptake inhibitors or SNRIs are the newest class of antidepressants. SNRIs work by increasing the levels of serotonin and norepinephrine that are active in the brain. Serotonin and norepinephrine are produced by nerves and released into the surrounding tissues where they can attach to nearby receptors on other nerves, thereby stimulating the other nerves. The released serotonin and norepinephrine then are taken up and released again by the nerves that produce them. SNRIs block the uptake ("reuptake") of the serotonin and norepinephrine so that more of the serotonin and norepinephrine are free in the tissues surrounding the nerves.
In choosing an antidepressant, the doctor will take into account the patient's specific symptoms of depression, as well as his or her age, other medical conditions, and medication side effects. Of particular importance is that children and adolescents continue to use antidepressant medication with caution because of uncommon instances in which minors become acutely worse instead of better while receiving this treatment.
The presence of maternal-fetal stress is another risk factor for depression. It seems that maternal stress during pregnancy can increase the chance that the child will be prone to depression as an adult, particularly if there is a genetic vulnerability. Researchers believe that the mother's circulating stress hormones can influence the development of the fetus' brain during pregnancy. This altered fetal brain development occurs in ways that predispose the child to the risk of depression as an adult. Further research is still necessary to clarify how this happens. Again, this situation shows the complex interaction between genetic vulnerability and environmental stress, in this case, the stress of the mother on the fetus.

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.
SAMHSA’s National Helpline, 1-800-662-HELP (4357), (also known as the Treatment Referral Routing Service) or TTY: 1-800-487-4889 is a confidential, free, 24-hour-a-day, 365-day-a-year, information service, in English and Spanish, for individuals and family members facing mental and/or substance use disorders. This service provides referrals to local treatment facilities, support groups, and community-based organizations. Callers can also order free publications and other information.
It is not uncommon to experience occasional and brief periods of feeling down and anxious. These episodes are not usually a cause for concern, and once passed, you are able to resume life as usual. But, if you suffer from depression and anxiety and your symptoms are present for more than two weeks, frequently recur, or are interfering with how you live your life, it’s time to get help.
Prioritize. Depression is frequently an overwhelming situation. At the same time that you are depressed and suffering, life demands do not stop. One way to reduce the amount of stress you experience is to prioritize the demands you are facing and then to attend to only the most pressing tasks. Enlist the help of other family members or friends to get the rest of your responsibilities done, or simply let them ride for a while. For instance, if you normally cook the evening meal for your family after returning home from a full day's work, perhaps you can figure out an easier way to get dinner on the table for a while (working to support the family is a higher priority than making sure that every meal the family eats is nicely balanced and well-presented).
If you think you may have depression, describe your symptoms to a doctor. Or, if you’re not able to do that, pull out your cell phone and type “depression” or “clinical depression” into Google; you’ll be able to take a clinically validated depression test, known as the PHQ-9 patient health questionnaire, immediately and see if your scores show that you have depression.
Different neuropsychiatric illnesses seem to be associated with an overabundance or a lack of some of these neurochemicals in certain parts of the brain. For example, a lack of dopamine at the base of the brain causes Parkinson's disease. There appears to be a relation between Alzheimer's dementia and lower acetylcholine levels in the brain. The addictive disorders are under the influence of the neurochemical dopamine. That is to say, drugs of abuse and alcohol work by releasing dopamine in the brain. The dopamine causes euphoria, which is a pleasant sensation. Repeated use of drugs or alcohol, however, desensitizes the dopamine system, which means that the system gets used to the effects of drugs and alcohol. Therefore, a person needs more drugs or alcohol to achieve the same high feeling (builds up tolerance to the substance). Thus, the addicted person takes more substance but feels less and less high and increasingly depressed. There are also some drugs whose effects can include depression (these include alcohol, narcotics, and marijuana) and those for whom depression can be a symptom of withdrawal from the substance (including caffeine, cocaine, or amphetamines).
Because depression can affect how a person acts, it might be misunderstood as a bad attitude. Other people may think the person isn't trying or not putting in any effort. For example, a negative or irritable mood can cause someone to act more argumentative, disagreeable, or angry. That can make the person seem difficult to get along with or cause others to keep their distance. Low motivation, low energy, difficulty concentrating, and thoughts of "why bother?" can lead someone to skip classes or school.
Depression symptoms take many forms, and no two people’s experiences are exactly alike. A person who’s suffering from this disorder may not seem sad to others. They may instead complain about how they just “can’t get moving,” or are feeling completely unmotivated to do just about anything. Even simple things — like getting dressed in the morning or eating at mealtime — become large obstacles in daily life. People around them, such as their friends and family, notice the change too. Often they want to help, but just don’t know how.
No matter how hopeless things may feel today, people can get better with treatment — and most do. The key to successful treatment is usually dependent upon the person recognizing there’s a problem, seeking out treatment for it, and then following the treatment plan agreed to. This can be far more challenging for someone who’s depressed than it sounds, and patience is a core necessity when starting treatment.

About Depression:  Feelings of depression may be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us feel this way at one time or another for short periods. But true clinical depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for an extended period of time.

The second most important way to help someone with depression is to offer emotional support. This support involves understanding, patience, affection, and encouragement to the depression sufferer. Engage the depressed person in conversation and listen carefully. Do not disparage feelings expressed, but point out realities and offer hope. Do not ignore remarks about suicide. Always take them seriously and report them to the depressed person's therapist.
TCAs are associated with a number of cardiovascular (heart and blood vessels) effects such as orthostatic hypotension and abnormal heart rates and rhythms. Orthostatic hypotension may lead to dizziness, falls, and fractures. Orthostatic hypotension may be managed by reducing or discontinuing the TCA dose, increasing salt intake, or treatment with steroids.

The birth of a baby can trigger mood swings or crying spells in the following days or weeks, the so-called baby blues. When the reaction is more severe and prolonged, it is considered postpartum depression, a condition requiring treatment because it can interfere with the ability to care for the newborn. Depression can also occur seasonally, primarily in the winter months when sunlight is in short supply. Known as seasonal affective disorder, or SAD, it is often ameliorated by daily exposure to specific types of artificial light.

The SSRI antidepressants can cause sexual dysfunction. SSRIs reportedly decrease sex drive (libido) in both men and women. SSRIs reportedly cause inability to achieve orgasm or delay in achieving orgasm (anorgasmia) in women and difficulty with ejaculation (delay in ejaculating or loss of ability to ejaculate) and erections in men. Sexual dysfunction with SSRIs is common though the exact incidence is unknown. Newer SSRIs like vortioxetine and vilazodone have little to no negative impact on sexual functioning. Furthermore, patients have reported sexual side effects with the use of other antidepressant classes such a MAOIs, TCAs, and dual-action antidepressants.
Patients often are tempted to stop their medication too soon, especially when they begin feeling better. It is important to keep taking medication therapy until the doctor says to stop, even if the patient feels better beforehand. Doctors often will continue the antidepressant medications for at least six to 12 months after symptoms are alleviated because the risk of depression quickly returning when treatment is stopped decreases after that period of time in those people experiencing their first depressive episode. Patients must stop some medications gradually to give the body time to adjust (see discontinuation of antidepressants below). For individuals with bipolar disorder, recurrent or chronic major depression, medication may have to become a part of everyday life for an extended period of years in order to avoid disabling symptoms.
When psychotherapy and antidepressants don’t work, clinicians may turn to other treatment options. Usually the first is to try and adjunct medication to the existing antidepressant medication. In more serious or treatment-resistant cases, additional treatment options may be tried (like ECT or rTMS). Ketamine infusion treatments also appear to be effective, but are generally not covered by insurance and the long-term risks are unknown.

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants. They are highly effective and generally cause fewer side effects than the other antidepressants. SSRIs help to alleviate symptoms of depression by blocking the reabsorption or reuptake of serotonin in the brain. Serotonin is a naturally occurring neurotransmitter (chemical) that is used by brain cells to communicate. As SSRIs mainly affect the levels of serotonin and not levels of other neurotransmitters, they are referred to as “selective.”
People get confused about the distinction between anxiety and depression for several reasons. The first is that, if they are receiving medication for an anxiety disorder, they're probably getting an anti-depressant medication. A group of anti-depressant medications known as the Selective Serotonin Reuptake Inhibitors (SSRI) have been demonstrated to be helpful with both anxiety and depression, and are now the preferred medication treatment for people who receive medication for anxiety disorders. Sometimes people with anxiety disorders receive these medications, find out they're taking an anti-depressant, and then wonder if that means they're depressed. It doesn't, not by itself.
Understanding the underlying cause of your depression may help you overcome the problem. For example, if you are depressed because of a dead-end job, the best treatment might be finding a more satisfying career rather than simply taking an antidepressant. If you are new to an area and feeling lonely and sad, finding new friends will probably give you more of a mood boost than going to therapy. In such cases, the depression is remedied by changing the situation.

Even in the most severe cases, depression is highly treatable. The condition is often cyclical, and early treatment may prevent or forestall recurrent episodes. Many studies show that the most effective treatment is cognitive behavioral therapy, which addresses problematic thought patterns, with or without the use of antidepressant drugs. In addition, evidence is quickly accumulating that regular mindfulness meditation, on its own or combined with cognitive therapy, can stop depression before it starts by effectively disengaging attention from the repetitive negative thoughts that often set in motion the downward spiral of mood.
Anxiety is an emotion characterized by feelings of tension, worried thoughts, and physical changes like increased blood pressure. People with anxiety disorders usually have recurring intrusive thoughts or concerns. They may avoid certain situations out of worry. They may also have physical symptoms such as sweating, trembling, dizziness, or a rapid heartbeat.

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.
Increasingly, doctors may use a combination of antidepressants from different classes or add a medication from a completely different chemical class, such as Abilify or Seroquel, that are thought to enhance the effectiveness of antidepressant medication more rapidly than adding or switching to a second antidepressant. Also, new types of antidepressants are constantly being developed, and one of these may be the best for a particular patient.
Selective serotonin reuptake inhibitors (SSRIs) were launched in the mid to late 1980s. This generation of antidepressants is now the most common class used for depression. Examples include citalopram (Celexa), escitalopram (Lexapro), paroxetine (Paxil, Pexeva), fluoxetine (Prozac, Sarafem), and sertraline (Zoloft). Two medicines, classified as "serotonin modulators and stimulators" or SMS's (meaning they have some similar properties as SSRIs but also affect other brain receptors) are vilazodone (Viibryd) and vortioxetine (Trintellix) Side effects are generally mild, but can be bothersome in some people. They include nausea, stomach upset, sexual problems, fatigue, dizziness, insomnia, weight change, and headaches.
Selective serotonin reuptake inhibitors (SSRIs) are medications that increase the amount of the neurochemical serotonin in the brain. (Remember that brain serotonin levels often are low in depression.) As their name implies, the SSRIs work by selectively inhibiting (blocking) serotonin reuptake in the brain. This block occurs at the synapse, the place where brain cells (neurons) connect to each other. Serotonin is one of the chemicals in the brain that carries messages across these connections (synapses) from one neuron to another.
Stay active. Exercise can make a difference to your energy levels and help stimulate hormones (such as endorphins) that help you feel better about yourself. Make a realistic goal to increase your level of activity. For example, if you’ve found it difficult even to get out of bed for the last few days, an achievable goal might be just to go for a walk outside in the fresh air for five minutes.

Once you have your list of questions, it’s time to seek out referrals. If you know other people in your area who suffer (or have suffered) from depression, ask them. Word of mouth can be a great way to find a good match. If this is not possible, begin with your physician. It’s always a good idea to get a physical if you suspect major depressive disorder because some medical problems can cause similar symptoms. If medical conditions are ruled out as a cause of the symptoms of depression, ask your primary care physician for a list of referrals for therapists.

Atypical antidepressants include bupropion (Wellbutrin, Wellbutrin SR), mirtazapine (Remeron), and trazodone (Desyrel). These agents are effective in treating major depression and may be effective in combination therapy in major depressive disorder. This group also shows low toxicity in overdose. Wellbutrin SR may have an advantage over the SSRIs by causing less sexual dysfunction and weight gain.

Therapy. Many people benefit from psychotherapy—also called therapy or counseling.7,8 Most therapy lasts for a short time and focuses on thoughts‚ feelings‚ and issues that are happening in your life now. In some cases‚ understanding your past can help‚ but finding ways to address what is happening in your life now can help you cope and prepare you for challenges in the future.With therapy, you’ll work with your therapist to learn skills to help you cope with life, change behaviors that are causing problems‚ and find solutions. Do not feel shy or embarrassed about talking openly and honestly about your feelings and concerns. This is an important part of getting better.Some common goals of therapy include:
Atypical antidepressants are considered “atypical” because these agents do not fit into any of the other classes of antidepressants. Each medicine in this category has a unique mechanism of action in the body. However, like other antidepressants, atypical antidepressants affect the levels of dopamine, serotonin, and norepinephrine in the brain. Brintellix and Viibryd inhibit reuptakeof serotonin but also act on serotonin receptors.
Invite the depressed person for walks, outings, and to the movies and other activities. Be gently insistent if the depressed individual refuses your invitation. Encourage participation in activities that once gave pleasure, such as hobbies, sports, or religious or cultural activities. However, do not push the depressed person to undertake too much too soon. The depressed person needs company and diversion, but too many demands can increase feelings of failure and exhaustion.
We know it can be tough take on any of these depression self help tips when you’re feeling really bad. Also, when it comes to self-help, strategies for feeling better are very individualistic. That is, different things work for different people. Not everyone will want to start doing yoga, for example, so keep trying different ideas even if the first thing you try doesn’t help.

Exercise and pleasurable activities are natural ways to improve mood. Exercise increases the levels of endorphins which can elevate mood. Foods high in omega-3-fatty acids may increase serotonin levels in the brain and contribute to relieving depression. During winter months some people may suffer from seasonal depression. Increasing exposure to light alleviates seasonal depression.
Anxiety Disorders are characterized by a sense of doubt and vulnerability about future events. The attention of anxious people is focused on their future prospects, and the fear that those future prospects will be bad. Anxiety Disorders are characterized by a variety of symptoms involving anxious thoughts, unexplained physical sensations, and avoidant or self protective behaviors.
The most important thing anyone can do for the depressed person is to help him or her get an appropriate diagnosis and treatment. This help may involve encouraging the individual to stay with treatment until symptoms begin to go away (usually several weeks) or to seek different treatment if no improvement occurs. On occasion, it may require making an appointment and accompanying the depressed person to the doctor. It may also mean monitoring whether the depressed person is taking medication for several months after symptoms have improved. Always report a worsening depression to the patient's physician or therapist.
Additionally, the symptoms must last for two or more weeks and cause significant disruption of life functions. But to be diagnosed with dysthymia, a person need only have two of the recognized diagnostic symptoms, one of which is a mood that is persistently dark or gloomy, and the symptoms must be present on most days for at least two years. It is possible to have periods of time that are “symptom free,” but the break cannot last longer than two months.
Clinical trials are research studies that look at new ways to prevent, detect, or treat diseases and conditions, including depression. During clinical trials, some participants receive treatments under study that might be new drugs or new combinations of drugs, new surgical procedures or devices, or new ways to use existing treatments. Other participants (in the “control group”) receive a standard treatment, such as a medication already on the market, an inactive placebo medication, or no treatment. The goal of clinical trials is to determine if a new test or treatment works and is safe. Although individual participants may benefit from being part of a clinical trial, participants should be aware that the primary purpose of a clinical trial is to gain new scientific knowledge so that others may be better helped in the future.
