Electric wheelchairs are wheelchairs that are motorized. Electric wheelchairs may be a necessity for people who do not have the upper arm strength or ability to use a manual wheelchair. Some people who are able to use in manual wheelchair may want to use an electric wheelchair, but may not be able to because of the increased cost of an electric wheelchair.

The required physical strength is much less for an electric wheelchair then for a manual wheelchair since an electric wheelchair is powered by a battery. The ease of use of an electric wheelchair as compared to a manual wheelchair is especially noticeable when the wheelchair user goes uphill or slanted surfaces.

If a doctor feels that the wheelchair user requires the use of an electric wheelchair, much of the cost of the electric wheelchair may be covered by insurance. Electric wheelchairs can cost thousands of dollars plus the cost of any modifications to the person's home or vehicle and maintenance equipment like batteries and battery chargers.

Some people may confuse an electric wheelchair with a mobility scooter. A typical mobility scooter has a handlebar for steering control in the front of the scooter. The steering of an electric wheelchair is controlled by a mechanism on the right armrest.

The maneuverability of mobility scooters is less than that of electric wheelchairs. The ease of negotiating corners and turns with an electric wheelchair depends on the model of the electric wheelchair.

There are three basic models of electric wheelchairs. The traditional model of electric wheelchair is the rear-wheel drive electric wheelchair. Of the basic models, the rearwheel drive has the least amount of maneuverability. The mid-wheel drive electric wheelchair as the highest level of maneuverability, but also has some instability during stopping and starting.

The front-wheel drive electric wheelchair is another option. They do not have the level of maneuverability that a mid-wheel drive electric wheelchair has, but they offer better maneuverability than the rear-wheel drive wheelchairs.

Because of their ease of use, and electric wheelchair often gives the wheelchair user more freedom than a manual wheelchair. The user of an electric wheelchair may not need a personal care assistant that they may require if they used a manual wheelchair. Electric wheelchairs also allow more for use of the hands.

Several different types of wheelchair accessories can be purchased for use with an electric wheelchair. Carriers for oxygen tanks and safety belts may be a necessity for some wheelchair users. Other wheelchair accessories like cupholders are for the wheelchair user's convenience.

Sudden hearing loss as adults can have an obvious cause such as an illness, accident, or injury. Sudden hearing loss can also be due to sudden hearing loss syndrome.

Sudden hearing loss syndrome, also called sudden deafness, is a significant hearing loss that develops within three days. For less than fifteen percent of the cases of sudden hearing loss syndrome, the cause of the hearing loss is identified. The condition may be called idiopathic sudden hearing loss if the cause is unknown.

There are about four thousand cases of sudden hearing loss syndrome a year in the United States. Adults between the ages of thirty to sixty are at the highest risk of sudden hearing loss syndrome.

A widely used method of treatment for idiopathic hearing loss is steroids, but there has been some debate about the effectiveness of this treatment. One study showed that steroids were no more effective than a placebo.

For about fifteen percent of people with sudden hearing loss syndrome, their hearing worsens over time. In most cases, the people with sudden hearing loss recover at least some of their hearing. Spontaneous recovery is the recovery of the hearing loss without a known cause for the recovery.

Sudden hearing loss can be caused by head trauma from an accident or interpersonal violence. Damage to the auditory nerve, a perforated eardrum, or a fracture of the temporal bone can cause sudden hearing long.

Sudden hearing loss from trauma can be surgically corrected in some cases. Sometimes, the injury causes permanent sensorineural hearing loss. A perforated eardrum often heals itself, but a large perforation may need to be surgically corrected.

Circulation problems, abnormal growths, some infectious diseases, neurological problems, exposure to toxic chemicals, and the toxicity of medications can cause sudden hearing loss. There are over one hundred possible cause of sudden hearing loss.

If a person experiences sudden hearing loss, the person should seek emergency medical treatment. Many doctors believe that prompt medical attention for sudden hearing loss syndrome can increase the chance of recovery of the lost hearing.

Bipolar III is not an official psychiatric diagnosis. The Diagnostic and Statistical Manual (DSM) is the reference book used to diagnose mental illnesses. Bipolar III is not included in the DSM.

The term bipolar III has two common uses. Cyclothymia is a mild form of bipolar disorder that is sometimes called bipolar III. Symptoms of mania caused by antidepressants may be called bipolar III.

Cyclothymia is a mild form of bipolar disorder that causes recurrent episodes of depression that are not severe enough to meet the criteria for clinical depression. These depressive episodes may be followed by episodes of hypomania. Cyclothymia is sometimes called soft bipolar since it is a mild form of bipolar disorder.

Cyclothymia may be diagnosed for people with recurrent depressive episodes even if they have never had an episode of hypomania if the person has a family history of bipolar disorder or a temperament with characteristics like optimism, overconfidence, extroverted, inflated self-esteem, and over-involvement in other peoples lives as well as a minimal need for sleep.

Bipolar III is also used in reference to mania that has been caused by excess antidepressants. People with bipolar disorder or clinical depression are commonly treated with antidepressants.

Antidepressants are often an important component in the treatment for mood disorders. Sometimes, a psychiatrist must try several different antidepressants and dosages before the right combination for the individual is found.

If the bipolar III is due to antidepressants, the psychiatrist will make adjustments to the dosage or change the prescribed medication. Bipolar III that is cyclothymia may be treated with medication and cognitive therapy.

If someone who is diagnosed with cyclothymia has a manic episode, the diagnosis is likely to be changed to bipolar I. Sometimes, people become frustrated by changing diagnoses, but sometimes it is necessary for a doctor to change diagnoses to reflect changes in the persons symptoms.
