Biofeedback for anxiety uses sensors to show your heart rate, breathing, muscle tension or brainwaves in real time so you can learn to calm your stress response. HRV biofeedback has the strongest evidence, led by a 2017 meta-analysis of 24 studies.
Ketamine can lift treatment-resistant depression within hours to days but usually fades without boosters, while TMS builds over a 4 to 6 week course and often lasts for months. Here is how the two compare on evidence, side effects, cost and insurance.
Migraine is a neurological disease causing recurrent attacks of severe head pain, affecting about 1 billion people worldwide, with up to 40 percent of patients not fully helped by standard medication.
Biofeedback therapy uses real-time sensor readings of muscle tension, skin temperature, heart rate variability, breathing and brainwaves to teach you to regulate them. Its strongest evidence is for tension-type headache and migraine, with moderate support for chronic back pain and anxiety.
Hyperbaric oxygen therapy (HBOT) is not FDA approved for TBI or concussion. Israeli trials reported cognitive gains after 40 sessions at 1.5 ATA, while US military sham-controlled trials found sham groups improved about as much.
Brain fog is a symptom, not a diagnosis: slowed thinking, poor focus and memory lapses that usually trace back to a testable cause such as thyroid disease, nutrient deficiency, sleep apnea, menopause, medications or Long COVID.
