Helmet therapy provides treatment for depression

Trans-cranial magnetic stimulation (TMS).

A machine resembling a dentist’s chair, called Neuro-Star, delivers electrical stimulation to Keeran’s brain using magnetic pulses similar to an MRI. The pulses are focused on specific neural pathways in the brain. The signal strength is controlled by her psychiatrist, Dr. Travis Svensson.

Svensson says that while the concept bears some resemblance to traditional electro-therapy, it actually works in a different way.

“Whereas other therapies like shock therapy create a seizure to release neurotransmitters, the goal for TMA is not to create a seizure,” he explained. “We’re not trying to release neurotransmitters. We’re trying to energize nerve tracks in the brain.” Link

Deep brain stimulation a the Mayo Clinic

How it works

A thin, insulated wire lead with four electrodes at the tip is surgically implanted into the affected area of the brain. A wire runs under the skin to a battery-operated pulse generator implanted near the collarbone. The generator is programmed to send continuous electrical pulses to the brain. It can be turned on or off when the patient swipes a special magnet over the generator. (Movement disorders patients typically turn off the device at night, because tremors usually stop during sleep.)

To implant the electrodes, a neurosurgeon uses a stereotactic head frame and magnetic resonance or computed tomography imaging to map the brain and pinpoint the problem area. The patient’s scalp is anesthetized before the procedure, but the patient is awake to report side effects while the electrodes are placed . This allows the lead to be placed for maximum effectiveness and minimum side effects. The patient will receive sedation or general anesthesia before the wire lead and the pulse generator are implanted.

Deep brain stimulation can be done on one or both sides of the brain, depending on the disorder and the patient’s problems.

Side effects are generally mild and reversible. The most common are a temporary tingling in the limbs, slight paralysis, slurred speech and loss of balance.

Battery life varies with usage and settings. The battery should last about five years with 16 hours of use a day. When the battery needs to be replaced, the pulse generator is replaced, usually while the patient is under local anesthesia during an outpatient procedure.

The procedure is expensive. It uses both sophisticated surgical and implanted equipment, in addition to the cost of surgery and hospitalization. Medicare and many insurance plans cover most costs associated with deep brain stimulation for movement disorders. Other uses of deep brain stimulation will likely be covered in the future.

Is The Rest Of The World ‘Crazy Like Us’?

Talk of the Nation, January 14:

Author Ethan Watters thinks that America is “homogenizing the way the world goes mad.” In Crazy Like Us: The Globalization of the American Psyche, he describes how American definitions and treatments of mental illness have spread to other cultures around the world.

“[McDonald’s] golden arches do not represent our most troubling impact on other cultures,” Watters writes. “Rather, it is how we are flattening the landscape of the human psyche itself. We are engaged in the grand project of Americanizing the world’s understanding of the human mind.”

Watters talks with NPR’s Rebecca Roberts about the cultural diversity of mental illness — and how that diversity is quickly disappearing. Listen or read.

The mental health field is plagued with the bigotry of low expectations. Far too many people are talking about “changing the stigma,” while creating the worst stigma of all–the idea that we are not capable of achieving greatness. – Bipolar In Order

Petroleum in out medications: So what happens when there is not enough petroleum remaining to make many of the products we’ve grown so accustomed to:

Of course, everyone realizes petroleum products are used in the gasoline we fuel our vehicles and in the heating oil we use to keep our homes warm. But did you know petroleum-based components are in medicines, food, plastics, and even in the clothes we wear? Not only is petroleum a source for fuel, but it has many other uses.

Petrolatum or better known as petroleum jelly is sometimes blended with paraffin wax and used in medicines and in many toiletries and healing moisturizers. Paints, lacquers, and printing inks all have within them petroleum-based solvents to make them flow better. Besides your automobile engine, all machinery, like the engine in your lawn mower, need lubricating oils and grease made from petroleum to keep them running smoothly. Petroleum (or paraffin) wax is used in packaging, candles, matches, shoe polish, and even candy making. Asphalt we use
to pave our driveways, roads and airfields is a byproduct of petroleum. Asphalt also is used to surface canals, dams, and reservoirs. We can find this in the linoleum we cover our floors with and in the shingles we put on our roofs.

Petroleum coke is used as a raw material for many carbon and graphite products. These products include furnace electrodes and liners and the anodes used in the production of aluminum. Aluminum is used in the construction of just about all of our everyday appliances.

Since the 1920’s, petroleum has been used as a feedstock in the production of petrochemicals. A liquid obtained from the refining of crude oil called naphtha is one of the basic feedstocks, Petrochemical feedstocks also include products recovered from natural gas, and refinery gases (ethane, propane, and butane). Petrochemical feedstocks are converted to basic chemical building blocks and intermediates, such as ethylene, propylene, normal- and iso-butylenes, butadiene, and aromatics such as benzene, toluene, and xylene.

Peak Oil defined:

“Peak oil” is the term used to describe the situation when the amount of oil that can be extracted from the earth in a given year begins to decline, because geological limitations are reached. Extracting oil becomes more and more difficult, so that costs escalate and the amount of oil produced begins to decline. The term peak oil generally relates to worldwide production, but a similar phenomenon exists for individual countries and other smaller areas.
