Molecular Imaging Shows Chronic Marijuana Smoking Affects Brain Chemistry

A collaborative study between the National Institute of Mental Health (NIMH) and the National Institute on Drug Abuse (NIDA) revealed that chronic marijuana smoking affects the brain chemistry. According to the NIDA, marijuana or cannabis is the mostly used illegal drug in America. As per the study, it was found that there was a decrease in the number of the cannabinoid receptors that are important for mental and physical functions like movement coordination, concentration, pleasure, memory, pain tolerance and appetite.

As a part of the study, 30 chronic daily cannabis smokers were monitored for approximately four weeks. These people were subjected to positron emission tomography (PET) to find the changes in the physiological processes in the body. A radioligand, 18F-FMPEP-d2 is a combination of radioactive fluorine isotope and a neurotransmitter analog which binds with CB1 brain receptors. It was found that the number of cannabis receptors in the cannabis smokers decreased about 20 percent when compared to healthy control subjects with limited exposure to cannabis during their lifetime.

When 14 of the 30 subjects were re-scanned after one month of abstinence, there was an increase in the receptor activity in the areas which were deficient at the beginning of the study. It indicates that the chronic cannabis smoking causes down regulation of CB1 receptors and the damage is reversible with abstinence. The information resulted from the study was found to be useful for the development of novel treatments for cannabis abuse. It also revealed that the decreased receptors in people who abuse cannabis return to normal when they stop smoking the drug.

Factors Affecting Dental Health of the Elderly

As one grows older, many health problems arise because of their weakened body systems. Among the many issues, oral health problems are common in the elderly. Various dental problems such as tooth loss, dental caries, periodontal diseases and so on are seen in senior people. Certain risk factors make them more prone to different kinds of dental issues.

Aging is the primary factor affecting dental health of the elderly. As they age, the gums begin to recede and this may further lead to many other dental problems. However, regular flossing and good oral hygienic practices can lessen the gum recession, thereby promoting healthy gums. Another important thing is that seniors suffer from a common problem, dry mouth. A dry mouth is a condition where the saliva content in the mouth is less. Certain medications may even promote this situation. As saliva in the oral cavity is less, there is less chance to throw away the bacteria and food particles. The deposition of these elements, however, causes plaque or tartar formation that can lead to gum diseases. It is even found that people, especially women, suffering from osteoporosis have a higher risk of periodontal diseases.

Elderly people face limits on insurance and money to afford for dental treatment. Hence, they avoid getting treatment for any dental issues that are already present. Another consideration is that they are unable to go to the dental office and neglect even if they suffer from serious oral problems. In addition, there are also very limited trained dentists who are willing to go to the elderly for checking their dental needs.

In addition to the above factors, poor diet, improper oral hygiene, side effects of medications and recurrent decay around older fillings are found to cause dental issues in the elderly.
