Brain stimulation treatments like TMS, ECT, and deep brain stimulation for treatment-resistant conditions.
Alpha-theta neurofeedback is a passive form of neurofeedback that encourages the production of alpha (8-12 Hz) and theta (4-8 Hz) brainwaves. This protocol is designed to access deep meditative states, enhance creativity, and facilitate emotional processing and trauma healing through brainwave entrainment.

Beta neurofeedback is a form of EEG biofeedback in which real-time brainwave amplitudes are displayed to the patient and used to reinforce desired changes in cortical activity via operant conditioning. Protocols commonly reward low- to mid-beta activity (e.g., 15–18 Hz) and/or sensorimotor rhythm (SMR; 12–15 Hz), while inhibiting excess theta (4–7 Hz) and high-beta (22–30 Hz). The goal is to optimize arousal regulation, sustain attention, and reduce hyperarousal and anxiety. Clinically, beta- and SMR-based protocols are most often applied in attention-deficit/hyperactivity disorder (ADHD) and insomnia, with exploratory use for anxiety and performance optimization. Evidence suggests small-to-moderate benefits for ADHD symptoms in some trials and meta-analyses, though findings are mixed and protocol heterogeneity and expectancy effects complicate interpretation. For insomnia, SMR training shows promise in select studies, but double-blind work highlights substantial placebo responsiveness. Careful patient selection, standardized protocols, and integration with behavioral treatments (e.g., CBT-I, psychoeducation) are recommended.

Blue light therapy involves exposure to light in the blue spectrum, typically between 450–495 nanometers, which has distinct biological effects compared to full-spectrum or white light. In mental health, blue light is primarily used for circadian rhythm modulation, seasonal affective disorder (SAD) treatment, and sleep-phase disorders by influencing melanopsin-containing retinal ganglion cells that project to the brain's suprachiasmatic nucleus (SCN). In dermatology, high-intensity blue light is employed for its antimicrobial and anti-inflammatory properties, often in acne treatment or as part of photodynamic therapy for certain precancerous skin lesions. The wavelength and intensity used in psychiatric versus dermatologic applications differ substantially, with psychiatric use focusing on safe daily exposure and dermatologic use often involving shorter, higher-intensity treatments.

Bright light therapy delivers controlled exposure to high-intensity light, typically between 2,500–10,000 lux, to influence circadian rhythms and improve mood. By stimulating intrinsically photosensitive retinal ganglion cells, light signals are transmitted to the brain’s suprachiasmatic nucleus (SCN), the body’s master clock, resulting in adjustments to melatonin and serotonin regulation. This treatment is widely used for seasonal affective disorder, certain circadian rhythm sleep-wake disorders, and as an adjunct in non-seasonal depression. The therapy involves sitting near a specially designed light box each morning, usually during the fall and winter months, to simulate natural outdoor light exposure. Bright light therapy is safe for most individuals when used as directed, though proper screening for ocular health and photosensitivity is recommended before starting treatment.

Coherence training, often facilitated through heart rate variability (HRV) biofeedback, teaches individuals to regulate their breathing, heart rhythms, and emotional states to achieve a state known as psychophysiological coherence. In this state, breathing, heart rate, and blood pressure patterns become synchronized, supporting improved autonomic nervous system balance. This approach has applications in stress reduction, anxiety management, trauma recovery, and performance optimization. Sessions often use computer or wearable devices that measure HRV and provide visual or auditory feedback to guide the participant toward optimal breathing patterns (often ~6 breaths per minute). By training consistent, rhythmic breathing and positive emotional focus, coherence training aims to enhance resilience, cognitive performance, and emotional stability.

Dawn simulation therapy uses a timed light device that gradually brightens over 30–90 minutes before a person wakes, mimicking the gradual light changes of a sunrise. This approach aims to gently shift the body's circadian rhythm, enhance morning alertness, and improve mood. Unlike bright light therapy, which uses high-intensity light shortly after waking, dawn simulation operates at lower lux levels (typically 100–300 lux at eye level) but over a longer ramp-up period. This gradual light increase can be less disruptive for light-sensitive individuals and may improve adherence. It is most often applied in treating seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, and certain cases of non-seasonal depression.

Deep brain stimulation (DBS) involves the stereotactic surgical implantation of electrodes into targeted brain structures, connected via subcutaneous leads to a neurostimulator (implanted pulse generator). The device delivers continuous or programmed electrical pulses to modulate abnormal neural circuit activity. DBS is FDA-approved for movement disorders such as Parkinson’s disease, essential tremor, and dystonia, and more recently for obsessive-compulsive disorder (OCD). Research is ongoing for treatment-resistant depression, Tourette syndrome, and other neuropsychiatric conditions. Unlike ablative neurosurgery, DBS is adjustable and reversible, allowing fine-tuning of stimulation parameters and the possibility of device removal if necessary.

EEG neurofeedback, also called EEG biofeedback or neurotherapy, uses electroencephalography (EEG) to measure brainwave activity and provides real-time feedback to the participant, often through visual or auditory cues. The participant learns to increase or decrease certain brainwave patterns associated with improved cognitive or emotional functioning. It is used both as a therapeutic intervention for clinical conditions and as a performance enhancement tool. Protocols are tailored to the individual's EEG profile and treatment goals, and sessions are typically repeated over several weeks.

Electroconvulsive therapy (ECT) is a safe, highly effective treatment primarily for severe depression, treatment-resistant mood disorders, and certain psychotic illnesses. It involves the administration of a short, controlled electrical stimulus to the scalp under general anesthesia, producing a brief therapeutic seizure. Modern ECT is performed with muscle relaxants and continuous monitoring to minimize risks. The treatment often leads to rapid symptom improvement, making it especially valuable in urgent or life-threatening psychiatric conditions.

Electroconvulsive Therapy for Severe Depression is a hospital-based medical procedure that uses brief electrical stimulation of the brain under general anesthesia. It is delivered in a controlled setting by a psychiatric and anesthesia team. ECT is most often used for people with severe, treatment-resistant depression or life-threatening symptoms such as suicidality or catatonia. While highly effective, it is not typically a first-line treatment and may cause temporary memory and cognitive side effects.

Electromyographic (EMG) biofeedback records surface muscle activity and provides real-time visual and/or auditory feedback so patients can learn to down-regulate excessive tension or up-train weak or poorly recruited muscles. Through operant conditioning and repeated practice, EMG biofeedback promotes more efficient neuromuscular control and reduces pain or hyperarousal associated with chronic tension patterns. In behavioral health, EMG biofeedback is most commonly applied to tension-type headache (frontalis, temporalis), migraine (pericranial co-contraction patterns), temporomandibular disorders and bruxism (masseter/temporalis), neck/shoulder myalgia (trapezius), and stress-related somatic symptoms. Evidence supports benefit for primary headaches and for adjunctive use in anxiety/stress management. EMG biofeedback devices are generally regulated in the U.S. as Class II biofeedback devices (often via 510(k)); they are cleared for biofeedback/relaxation training rather than specific psychiatric indications.

Galvanic Skin Response (GSR) biofeedback—also called electrodermal activity (EDA) biofeedback—measures changes in skin conductance associated with sweat gland activity, a sensitive marker of sympathetic nervous system arousal. Real-time visual and/or auditory feedback helps patients notice and modulate arousal states using paced breathing, relaxation, and cognitive strategies. Clinically, GSR biofeedback is used to reduce stress and anxiety, improve emotion regulation, and support trauma recovery when integrated with evidence-based psychotherapies. It can also augment relaxation training for insomnia and somatic tension syndromes. Devices are recording-only (no current delivered) and are generally regulated as biofeedback/relaxation tools rather than for specific psychiatric indications.

Glabellar botulinum toxin injection involves administering botulinum toxin type A into the muscles of the glabellar region (between the eyebrows) to reduce hyperactivity of the corrugator and procerus muscles. While its primary use is cosmetic (to reduce frown lines), clinical trials have investigated its role in alleviating symptoms of major depressive disorder. The hypothesized mechanism is based on the facial feedback hypothesis, where reducing the ability to form negative facial expressions may improve mood states. This treatment is minimally invasive and performed in an outpatient setting.

Glabellar Botulinum Toxin Injection for Depression is an outpatient injection of botulinum toxin type A into the frown muscles between the eyebrows. A trained clinician injects small amounts into the corrugator and procerus muscles in a brief visit, with effects building over the first week and lasting a few months. It may help some adults with major depressive disorder, possibly by reducing negative facial feedback signals to emotion circuits. It is not first-line care for depression, and evidence is still evolving.

HRV biofeedback (often called coherence training) uses sensors to measure beat-to-beat heart rate changes and provides real-time feedback to guide slow, diaphragmatic breathing near the individual's resonance frequency (~4.5–6.5 breaths/min). Training increases vagal tone and baroreflex sensitivity, promoting parasympathetic dominance and improved stress recovery. Clinically, HRV training is used for anxiety and stress-related disorders, PTSD adjunctive care, insomnia, functional somatic syndromes, and performance optimization. Sessions combine breathing pacers, HRV coherence targets, and brief challenge–recovery drills to generalize self-regulation skills to daily life.

Infrared light therapy uses wavelengths beyond the visible spectrum (typically 700–1,000+ nm for near-infrared, and 3,000–100,000 nm for far-infrared) to penetrate tissues and trigger photobiomodulation. Near-infrared wavelengths penetrate deeper into muscles, joints, and sometimes brain tissue, influencing mitochondrial activity and promoting cellular repair. Far-infrared primarily generates gentle heat, improving circulation and tissue flexibility. Both modes can modulate inflammation, reduce pain, and support recovery. It is applied via LEDs, laser diodes, or infrared heat panels, often for musculoskeletal injuries, neuropathic pain, arthritis, and emerging mental health and neurorehabilitation contexts.

IV ketamine infusion involves administering a sub-anesthetic dose of ketamine via intravenous drip under medical supervision. It is known for its rapid onset antidepressant effects, often within hours, making it a promising option for treatment-resistant depression, suicidal ideation, and certain pain syndromes. Ketamine acts primarily as an NMDA receptor antagonist, leading to downstream effects on glutamate signaling, neuroplasticity, and brain-derived neurotrophic factor (BDNF) release. Treatments are performed in clinical settings with continuous monitoring due to the potential for dissociation, cardiovascular effects, and other acute side effects.
