Depression is related to human feelings which we can’t see and touch.

In this busiest 21st century, where the competition of excellence and distinction drives our lives, people are suffering from anxiety and depression.

One can feel depression and express it in a different manner. Science is researching on it and trying to help people to get relief from this mental condition. There is already much advancement with current medical and psychological therapies.  The resistant cases i.e. patients who do not get benefit from current possible therapies may require the use of electric shock in a therapy called Electroconvulsive therapy.

There is one step forward in the treatment of depression and Medical technology has introduced several devices to help people with depression.

Depression

On depression

Depression is a clinical syndrome comprising of several symptoms. In order to diagnose depression, 5 out of 9 symptoms should be present for at least 2 weeks. These symptoms include;

  • Feeling Sad
  • Loss of interest
  • Weight loss
  • Loss of sleep
  • Loss of energy/fatigue
  • Feeling guilty/worthless
  • Difficulty in concentration
  • Suicidal ideation
  • Slowed speech

The Wonderful Innovations:

Trans-cranial magnetic stimulation (TMS):

This is quite an impressive innovation.

TMS

How TMS may help people with depression

TMS is a non-invasive method of motivating the brain. It uses an electromagnet that is placed outside the patient’s head and targeted at one particular part of the brain. It turns on a magnetic field that is as solid as a regular MRI but lasts less than half of a millisecond.

This magnetic field turns on or off neurons in the brain, such as those that contribute to depression. If this is done repeatedly over time, it ends up retraining the specific circuits that we are pointing to function correctly on their own.

TMS approval by Neurologists:

Neurologist approved this treatment of depression and it’s being studied in a variety of other circumstances. It’s the first treatment approach that takes particular circuits in the brain as a primary target and affects them directly to treat depression.

Computer-Based Training:

Another method to treat depression is computer-based training. It helps people to reduce depression.

Computer training tries to tie an understanding of what is wrong with the brain with a task that directly exercises area of the brain involved in depression. In this training, the patient is given a particular task quite frequently. This task is made tougher every time.

The idea is that the brain circuit connected with the mental illness will then function better in other situations of daily life.

By these tasks, patients develop an interest to do more rather than feeling like being in a laboratory research. For example, they might also see birds flying by, or see something jumping on the horizon, and they need to click on it with the full attention of mind.

It feels like a video game, but under the cover, it is working and improving particular cognitive functions by making patient’s work quicker, and with greater precision.

It has been shown to work best for depressive patients and is moving towards researcher’s approval in the next couple of years. Some patients with depression have a very profound cognitive impairment in something called executive function. That is your ability to think openly, shut out distraction, switch between tasks, retain information in your mind and control it.

If you train people with schizophrenia to do these functions and make them harder at every level, they actually get better at those functions and better in terms of dealing with life in general. They are not cured, but it is something that current medications cannot do.

What about ECT?

ECT

In the 1930s, ECT was discovered when researchers learned that applying a small amount of electrical current to the brain caused mild seizures that changed brain’s chemistry. Over the years, much has been done to make this form of treatment milder and easier for people to tolerate.

During ECT, a machine is used to send small electrical currents to the brain. These currents affect the area of the brain that lasts about 30 seconds. Treatment is usually two or three times a week over a few weeks. ECT can be effective in treating severe depression. However, there can be side effects such as confusion and memory loss. The process must be performed in a hospital with general anesthesia.

Biofeedback

Biofeedback

Biotechnology has introduced another new technique,” Biofeedback.” It is a technique that helps people to control their symptoms by taking deep breaths, relaxing muscles, or changing feelings. In biofeedback, there is a device that can be worn or attached to a finger or ear that measures things like your heart rate, muscle tension, and breathing.

The user receives a response from the device in the form of beeping or flashing. As one changes their physiological reaction, the feedback they receive will change. This can relief an individual, who can learn the things that will decrease the symptoms they are facing. Eventually, people will be able to utilize these skills without the use of a device.  Biofeedback can be used for a variety of issues including anxiety, chronic pain, and headaches.

VNS- Vagus Nerve Stimulation:

VNS

Researchers invented a small battery-powered device with the name of VNS. It involves implanting a device similar to a pacemaker, under the skin on the left side of the chest. The device is encoded to deliver a mild electrical stimulation to the vagus nerve.

The doctors have approved VNS therapy for people of 18 years of age or older who are experiencing chronic or recurrent treatment-resistant depression. The treatment has been shown to be equally effective in both unipolar depression and bipolar disorder. The antidepressant effect of VNS tends to build up slowly and continue over time. The most common side effects of VNS are hoarseness, sore throat and shortness of breath.

Cranial Electrotherapy Stimulation devices work by sending a low-level electric current across the head and brain in short spouts. The force of the current is at a level that people often do not feel. The device is usually attached to the head via a headband or by clips that are worn on the ears. Developers of these devices indicate that they are effective in treating depression, anxiety, and sleeplessness.

Conclusion:

The future of the treatment for depression could be as simple as wearing a headset. In any case, many exciting technology-based treatments are well within our grip, so the future for treating depression seems quite bright.
