Hey there! This is Kate from MinuteEarth. Let’s dive into a fascinating topic about a treatment for severe depression that has made a comeback. In the mid-1900s, doctors used a method called “electroshock therapy” to help people with serious depression. This involved placing electrodes on a person’s head and sending an electrical current through the brain to cause a brief seizure. While it was effective, it also had some pretty harsh side effects, like broken bones and temporary memory loss. As people became more aware of these issues, the use of electroshock therapy declined.
Despite its rough reputation, electroshock therapy worked for about two-thirds of the patients, which was more successful than many medications at the time. Scientists think that depression might be linked to irregular electrical signals in the brain. By causing a seizure, the therapy might “reset” the brain’s electrical activity. Some doctors continued using this treatment but made improvements to reduce side effects. They started targeting the electrical current to one side of the brain and used anesthesia and muscle relaxants to make the process more comfortable.
Today, this treatment is known as “electroconvulsive therapy” (ECT). While it can still cause headaches and some short-term memory loss, it’s very effective in treating depression. This success has inspired doctors to explore electrical therapies for other brain disorders. For example, in people with advanced Parkinson’s disease, irregular electrical activity can cause problems like immobility and muscle twitching. By sending regular electrical pulses to specific brain areas, doctors can help these patients move more easily and reduce tremors.
Many other brain conditions also involve disrupted electrical signals. As research continues, electrical therapies might help even more people with different brain disorders. It’s an exciting area of study that holds a lot of promise for the future.

Hi, this is Kate from MinuteEarth. In the mid-20th century, a standard treatment for severe depression involved attaching electrodes to a patient’s skull and running an electrical current through the brain, which would induce a brief seizure. This process, known as “electroshock therapy,” was quite harsh and sometimes resulted in broken bones and temporary memory loss. Over time, public awareness of these side effects led to a decline in the use of electroshock therapy.
However, the treatment was effective, alleviating depression in about two-thirds of patients, which was more than those who responded to medication. It is believed that depression may arise from irregular electrical signals in the brain. Inducing a seizure through electrical stimulation might act like a “reset” for the brain. Some doctors continued to use electroshock therapy despite its controversial reputation, but they began to refine the approach by targeting the current to one side of the brain to minimize memory effects and using anesthesia and muscle relaxants to reduce discomfort.
Today, the treatment is referred to as “electroconvulsive therapy.” While it can still cause headaches and some short-term memory loss, its effectiveness in treating depression has encouraged doctors to explore electrical therapies for other brain disorders. For instance, in patients with advanced Parkinson’s disease, irregular electrical activity can lead to immobility and muscle twitching. By sending regular electrical pulses to the brain regions responsible for movement, doctors can help interrupt these misfires, allowing patients to move more freely and experience fewer tremors.
Many other brain conditions also involve disrupted electrical signaling, so electrical therapies may offer benefits to a wider range of individuals in the future, provided that research continues to advance.

Depression – A mental health disorder characterized by persistently low mood and a lack of interest in activities. – Many teenagers experience depression, which can affect their daily lives and relationships.
Therapy – A treatment intended to relieve or heal a disorder, often involving talking with a mental health professional. – She attended therapy sessions to help manage her anxiety and improve her mental well-being.
Electrical – Relating to electricity, often used to describe activities or signals in the brain. – The electrical activity in the brain can be measured using an EEG during sleep studies.
Brain – The organ in the head that controls thoughts, memory, emotions, and the nervous system. – The brain is responsible for processing information from our senses and coordinating our actions.
Seizure – A sudden, uncontrolled electrical disturbance in the brain that can cause changes in behavior, movements, feelings, or consciousness. – After experiencing a seizure, the patient was taken to the hospital for further evaluation.
Patients – Individuals receiving medical care or treatment, especially in a hospital or clinic. – The hospital staff worked hard to ensure that all patients received the best possible care.
Signals – Electrical impulses that carry information through the nervous system, including the brain. – Neurons in the brain send signals to each other to communicate and process information.
Memory – The ability to store, retain, and recall information and experiences in the brain. – Studying regularly can help improve your memory and make it easier to recall information during exams.
Doctors – Medical professionals who diagnose and treat illnesses and injuries. – Doctors often work with psychologists to provide comprehensive care for patients with mental health disorders.
Disorders – Conditions that disrupt normal physical or mental functions, often requiring medical attention. – Eating disorders can have serious health consequences and often require professional treatment.
