Medical procedures and tests can be frightening for both parents and children, so it’s important that you’re both prepared and calm.

The U.S. National Library of Medicine offers these suggestions:

* Give your child a detailed, simple and clear explanation of what is going to happen.
* Be specific about which part of the body will be affected, and how it might feel.
* Allow your child to react — even if it includes anger, screaming or crying — but encourage communication about what he or she is feeling.
* Have your child practice the position that will be required — such as lying down, stretching out an arm, or curling up on one side.
* Talk about why the test or procedure is necessary and how it will help your child.
* Let your child make decisions whenever possible, such as the color of the bandage that may be applied.

To come to this conclusion, French researchers looked at more than 12,000 couples who went to a fertility clinic in France.

In most of the cases, the couples were being treated due to the man’s infertility. The couples underwent a total of 21,239 intrauterine inseminations (IUIs).

The researchers found that women over age 35 had a pregnancy rate of 8.9 percent, compared to 14.5 percent in younger women.

The precise reasons why high blood pressure might increase the risk of dementia are not fully understood although many scientists believe that it can starve the brain of bloodflow and the oxygen it carries.

Patients suffering this restricted bloodflow are often described as having “vascular dementia”, and account for approximately a quarter of dementia patients.

So its good if people take precautions at middle age to controll blood pressure to reduce the risk of dementia at a later age.
