Learning about anxiety disorder

Both fear and anxiety send signals through the body that prepare all systems for possible danger. Hormones, such as adrenaline and catecholamine, are released in what is known as the "fight or flight" response. The sudden increase in hormone levels speeds up the heart and increases the amount of blood being pumped. At the same time, the muscles tighten, increasing the individual's ability to fight or flee from danger. The intensity of these physiological responses varies according to the seriousness of the event or thought that sparked the emotion, the strength of the individual's fear or anxiety, and his or her previous experience and genetic makeup.

Also, research indicates that other brain parts called the basal ganglia and striatum are involved in obsessive-compulsive disorder.

Scientists are also conducting clinical trials to find the most effective ways of treating anxiety disorders. For example, one trial is examining how well medication and behavioral therapies work together and separately in the treatment of obsessive-compulsive disorder. Another trial is assessing the safety and efficacy of medication treatments for anxiety disorders in children and adolescents with co-occurring attention deficit hyperactivity disorder. For more information about clinical trials, for example the National Library of Medicine's clinical trials database.

Hair care and hair treatment

General debility, caused by severe or long standing illnesses like typhoid, syphilis, chronic cold, influenza and anaemia, also gives rise to hair disorders. It makes the roots of the hair weak, resulting in falling of hair. An unclean condition of the scalp can also cause loss of hair. This weakens the hair roots by blocking the pores with the collected dirt. Heredity is another predisposing factor which may cause hair to fall.

Scalp reduction is performed on patients with well-defined bald spots in the crown area of the scalp. It is sometimes done in conjunction with hair transplantaion to reduce the size of the bald scalp, especially in patients who do not have enough donor hair to cover the bald areas.

For men, hair loss is male pattern baldness. Yes, there are other types of hair loss, including rare conditions such as alopecia totalis and alopecia universalis, where the entire scalp and entire body, respectively, become completely bald due to a viral condition that is irreversible. There is also patch baldness, in which hair falls out in patches of the scalp. This is caused by stress or poor nutrition or adverse scalp conditions. But the hair will usually grow back once the cause has been rectified.

The effectiveness of medications used to treat alopecia depends on the cause of hair loss, extent of the loss and individual response. Generally, treatment is less effective for more extensive cases of hair loss.

High Fever, Severe Infection, Severe Flu - Illnesses may cause hairs to enter the resting phase. Four weeks to three months after a high fever, severe illness or infection, a person may be shocked to see a lot of hair falling out. This shedding usually corrects itself.

Hair Pulling (Trichotillomania) - Children and sometimes adults will twist or pull their hair, brows or lashes until they come out. In children especially, this is often just a bad habit that gets better when the harmful effects of that habit are explained. Sometimes hair pulling can be a coping response to unpleasant stresses and occasionally is a sign of a serious problem needing the help of a mental health professional.

What is our skin?

Blood capillaries are found beneath the epidermis, and are linked to an arteriole and a venule. Arterial shunt vessels may bypass the network in ears, the nose and fingertips.

Dry skin is very common, especially with age. Older skin has fewer sweat and oil glands than younger skin. Dry skin may be caused by frequent baths, certain cosmetics or medications. But whatever the cause, there are ways to alleviate the itchiness associated with it. Avoid using harsh soaps when bathing, and if possible, cut back on the number of baths or showers each week. A sponge bath with warm water may help to clean and revive skin without stripping the skin of its valuable moisturizers.

Unless your skin is very oily, you will want to use a moisturizer everyday to keep your skin hydrated and healthy. Your skin needs moisturizer all year long as both the indoor winter heat, and summer sun can be equally damaging to your skin.
