Antidepressants alone may fail to help an estimated one-third to one-half of depressed patients.

Treatment for depression has historically hinged on the theory that the condition was caused by underactive or abnormal neurotransmitters, specifically serotonin and norepinephrine. This four-minute video by Yale Medicine details how these neurotransmitters didn't explain the symptoms of depression but, two other neurotransmitters involved in regulating mood and emotion did. GABA and glutamate, some of the brain's most plentiful neurotransmitters, may possibly be the source of depressive symptoms.

Major depressive disorder is a clinical diagnosis and is not a lifestyle choice. Those who struggle with depression can express persistent feelings that are difficult to process and make sense of for friends and family. This guide walks through some counterintuitive perspectives, including resisting the urge to force a depressed person to do the things that would make them feel better.

A US government report indicates that about 10% of US adults took prescription medication for this disorder in 2023. Women, at 15.3%, were more than twice as likely to take one of these medications than the 7.4% of men.

Clinical trials showed a 44% reduction in risk for recurrence of SAD for those who took the drug compared to a placebo group. Bupropion is a norepinephrine–dopamine reuptake inhibitor, which increases dopamine (other common antidepressants, known as selective serotonin reuptake inhibitors, sometimes can suppress dopamine, but not always).

Activities like exercise, even at low levels, have been shown to alleviate some of depression's symptoms for some people. However, depression saps energy levels, making it particularly difficult to motivate oneself to take helpful action.

A study led by a team from Stanford University showed that MR can help people with depression by providing pathways to engage in activities such as digital board games and dancing. Participants saw reduced symptoms of depression that made their overall treatment plans more successful.

LSD and psilocybin have shown promise as antidepressants. Using a virtual library of similar chemical compounds, researchers determined via animal studies that two molecules inspired by LSD have antidepressant effects without any associated hallucinogenic experience. These molecules were found to be 40 times more potent than the common antidepressant fluoxetine, also known as Prozac, with antidepressant effects lasting up to 21 days.

How magical are magic mushrooms, at least where depression is concerned? Some 24 volunteers participated in a study to evaluate the efficacy of using psilocybin in combination with psychotherapy to treat individuals suffering from depression. While some controversies remain about its use—psilocybin is known to cause psychosis sometimes—some scientists think the benefits outweigh the risks.

Proponents say this short-acting psychedelic, formally known as dimethyltryptamine, could be particularly promising for medicinal use because longer-acting psychedelics can sideline someone for hours after a treatment with hallucinations. DMT is the primary psychoactive ingredient in ayahuasca, a psychoactive brew used across various South American cultures for spiritual, social, and medicinal purposes.

Depressed brains can have certain characteristic changes, including an overactive amygdala, reduced hippocampus size, and changes to the thalamus and neuromodulating chemicals in the brain.

The country green lighted the treatments for July 1, 2023, onward, with MDMA—ectasy—as a post-traumatic stress disorder treatment, and psilocybin—magic mushrooms—as an option for people with treatment-resistant depression.

Scientists are investigating psilocybin, ketamine, LSD, and MDMA (also known as ecstasy) as potential treatments for mental health issues. These drugs enable an altered state of consciousness, which can have beneficial or harmful impacts depending on the nature of the experience. Research suggests these drugs can be effective in treating substance use disorders, mental health conditions, including depression and anxiety, and psychiatric disorders, including schizophrenia.

The American Psychiatric Association's DSM-5—used for defining diagnoses—says a person must be experiencing five or more symptoms of depression most of the day over at least two weeks. Research indicates older people are less likely than younger people to meet that depression benchmark, though this article says they still often have at least several of the depression symptoms.

This 101-style explainer on selective serotonin reuptake inhibitors explains how they work in the brain—complete with classroom-style whiteboard drawings. It covers common SSRIs, why someone might try this medication, and a deeper discussion about potential side effects.

An icy water exposure can lead to the release of norepinephrine, cortisol, dopamine, and other stress hormones that are beneficial, among other potential effects. Some data shows that this type of exposure can help combat depression symptoms among some patients, but more research is still needed.

Many think that yoga's combination of stretching, focused breathing, and contemplation help treat depression and anxiety, but the data has often relied on small, homogenous sample sizes.

This article explores whether the therapeutic potential of psychedelic drug use is really as good as current research suggests. Scientists are exploring its applications for conditions ranging from the existential crisis that can accompany terminal diagnoses to chronic mental health conditions, including anxiety and PTSD.

Before professional standards were adopted, practitioners used varying criteria to diagnose mental health disorders. By the 1970s, more objective lists were organized, culminating in this list of polythetic criteria—a list of symptoms where no single criterion is required, but a minimum number must be present.

LSD, psilocybin, and MDMA can suppress the brain's default mode network and enhance connectivity. Research shows that, when paired with therapy, psychedelics may help treat mental health conditions, including depression, addiction, and PTSD.

Though other antipsychotics block dopamine receptors, a new drug, Cobenfy, influences dopamine levels via a different pathway—it stimulates a pair of specialized receptors in the brain that control the release of a substance called acetylcholine. This alternative approach may help patients avoid serious side effects like weight gain.

Schildkraut was one of the first to put forward this idea, which stemmed from lab animal research. A decade later, researchers published the first landmark paper on fluoxetine—better known by trade name Prozac—which increases serotonin levels in the brain.

Critics argue that deep brain stimulation should be considered a last resort and not a scalable solution, given its high costs and trials limited to small samples. However, it has helped some patients manage severe opioid use disorder when conventional methods didn’t work.

There are two types of this disorder. Bipolar 1 features a significant manic episode—abnormally elevated mood and frantic energy—followed by repeated depression, while Bipolar 2 vacillates between depressive episodes and hypomania, a milder form of mania, but not a full mania. Listen to this podcast as experts explain the condition.

Certain antidepressants, antimalarial medications, antibiotics, ibuprofen, and cancer drugs have been linked with the condition. At higher doses, particularly, it seems they can trigger or worsen tinnitus in some individuals.

Dr. Roland Griffiths helped lead the revival of psychedelic research, often prescribing the use of psilocybin to address severe depression or anxiety in patients. This podcast explores how Griffiths leaned on his own career after being diagnosed with cancer and facing the prospect of death.

Researchers report that virtual reality and psychedelics may be leave users with similar insights and therapeutic benefits. Try out this free psychedelic virtual reality experience to see if this holds true for you. According to the program’s creators, a study into the efficacy of this 45-minute experience indicates it may help alleviate symptoms of mild to moderate depression.

More than 18% of US adults reported that they currently have or are being treated for depression in both 2024 and 2025. In the 2025 survey, more than 11,000 adults were surveyed. The numbers have ticked upward since 2015—by about 8 percentage points—with most of the increase occurring from the 2020 pandemic onward.

This prevalence trend mirrors the broader incidence of depression among women and is well-documented. Researchers suggest the disparity stems from differences in hormones, social role expectations, coping mechanisms, and more. Men may also present with depression differently, and seek help less.

What makes therapy work well is the connection that patients feel with their therapist, and the trust in that relationship. Some research suggests that while the therapeutic model—say cognitive behavior therapy or psychodynamic therapy—accounts for roughly 15% of outcomes, the therapeutic relationship with the therapist accounts for more than 30%.

Subsyndromal affective disorder is diagnosed when someone exhibits two of the nine major criteria for depression (but not more than five) as a result of seasonal changes. While it is milder than primary SAD, SSAD is still significant and impacts millions.

Brain imaging shows that ayahuasca, MDMA, DMT, and psilocybin profoundly affect neural activity, giving rise to higher states of introspection and consciousness. This article details exactly how each of these drugs physically affects the brain and what that means for mental health treatment. Some of these drugs quiet the brain or trigger the release of neurochemicals associated with mood regulation and learning.

A large analysis of existing studies published in 2021 found that systemic inflammation is associated with fatigue, appetite changes, and sleep disruption, rather than some of depression's broader symptoms including hopelessness about the future, or feeling fearful. This may suggest that inflammation influences specific symptoms of the condition, rather than the disease as a whole.

The decision was considered to be a major setback for moving psychedelics into the mainstream for mental health treatment. Pharmaceutical company Lykos, who had applied for the approval, had already attracted significant support from patients, politicians on both sides of the aisle, and leaders in the mental health field.

A recent analysis investigating the effects of menopause and HRT use on mental health, cognition, and brain health suggested HRT did little or nothing to aid with mental health and sleep. But the researchers caution that, among other data gaps, they didn't have information on which HRT formulations were used among their nearly 125,000 participants, so results may have varied by drug treatment.

Small, frequent doses can be more effective than large amounts, though caffeine can raise blood pressure and heart rate, especially in people with hypertension. While low doses of caffeine may help with depression by stimulating dopamine, excessive caffeine, particularly from energy drinks, can lead to anxiety and heart issues.

This podcast with a nutritionist and a medical doctor discusses how useful semaglutide can be for weight loss. It also outlines the need for patients to set reasonable expectations and to make changes to both diet and exercise as part of an overall weight management strategy. The experts note that failure to make meaningful changes outside of using semaglutide may mean patients need to stay on the drug in order to keep the weight off.

Those with ADHD—chronic issues with attention and executive function—are primed for SAD. Many are disproportionately evening chronotypes (more awake in the evening), have a delayed sleep phase, and have low sensitivity to light in the morning. This podcast explores the overlap between these two groups.

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.

Steps such as exercise, breathing, mindful eating, and spending time with friends, can help alleviate the fight-or-flight mode response of the body to alleviate stress, but they don't fix the stressors causing the burnout. To address those, workplaces may need to consider how to better manage workloads and duties.
