The U.S. Food and Drug Administration has not approved any medication for the treatment of behavioral agitation in dementia. However, the first line of defense is usually a traditional major tranquilizer such as haloperidol (Haldol), thioridazine (Mellaril), thiothixene (Navane) or perphenazine (Etrafon, Trilafon).
Yawning is a reflex action, which causes us to open our mouth wide and inhale a large amount of air, which is then followed by its exhalation.Though yawning is more commonly associated with boredom, fatigue, sleepiness, overwork or stress, many of us also yawn when we wake up or simply when see others yawn.ut of the various theories regarding what causes a yawn, the most important ones are given below. A yawn is contagious, in the sense that it can easily spread to the person who is observing the other person yawning.
A long-standing hypothesis is that yawning is caused by an excess of carbon dioxide and lack of oxygen in the blood. The brain stem detects this and triggers the yawn reflex. The mouth stretches wide and the lungs inhale deeply, bringing oxygen into the lungs and hence to the bloodstream.s such, the stretching of jaw and face muscles seems to be necessary for a good yawn.The yawn reflex is often described as contagious: if one person yawns, this will cause another person to sympathetically yawn. The reasons for this are unclear; however, recent research suggests that yawning might be a herd instinct.
