Alzheimer Begins with the Reduced Smell

Alzheimer begins with the reduced smell. If the sensitivity of the nose is weak, should be wary. Researchers say, a diminished sense of smell is an early sign of dementia or Alzheimer‘s disease. A recent study found an association between the development of foreign protein beta amyloid plaques in the brains of people with early dementia which is the cause of Alzheimer‘s disease with the ability to smell is getting worse.

Mice used in this study. Ability or the olfactory sense of smell in mice aged 3 months (same age young adults) who suffer from Alzheimer‘s was reported to decline as the development of amyloid beta protein.

In the journal Neuroscience mentioned that the results of the present invention can be applied to replace the techniques commonly used brain scans to detect Alzheimer‘s disease memory loss.

This is good news because for the early diagnosis of Alzheimer‘s disease do not need to do a brain scan first. Compared with MRI brain scans, test olfactory skills in the laboratory or the sense of smell is much cheaper. This is a pretty good alternative to encourage someone to test this disease without having to worry about the price.

Distinguishing Normal Snot and Infected Snot

Infected Snot

Infected Snot

Distinguishing normal snot and infected snot can be seen from its symptoms. Snot coming out of the nose not only appeared when people cold. But several other conditions such as allergies or trauma also triggers the release of snot. Mucus is generally produced by cells lining the sinus tract. This fluid serves to keep the nasal membranes (nose) remain moist, as well as useful for fighting infections and irritation.

Snot who appears not only caused by infection. Several other conditions also can trigger allergies such as runny nose, trauma (impact), irritation or exposure to air pollution, use of drugs that is sprayed into the nose or a problem with the anatomy of the nose. Here’s the difference:
1. If the snot that arise due to allergies, trauma (impact), irritation or exposure to air pollution, use of an inhaler or nasal anatomy problem, it does not contain infectious bacteria, viruses or other microorganisms.

2. Snot that appear colorless or clear snot is not the type of infection.

3. If the mucus in the nose is yellow, green or brown, it could be a sign of infection in the upper respiratory tract.

4. Debit or volume of snot that comes out could be a sign of sinus infection caused by bacteria. If the numbers are many and often it sign no infection.

5. Mucus containing bacteria is usually accompanied by headache, pain in the face, especially when you’re bent over, fever, bad breath, can not smell the odors, ear problems or persistent cough.

In bacterial infections generally last more than 7 days and mucus actually deteriorated over time. If caused by bacteria, then needed the help of antibiotics to cure but not for viral infections.
