What is the nervous system designed to do? Nerves make the arms and legs move. Nerves make the heart beat and the lungs breathe. Ultimately, the entire nervous system is designed to keep the body alive. That is its most primal function. If a lion is chasing, the body runs. If the hand touches something hot, it jerks away. Just like a built-in alarm system, this system of nerves will alert the body to danger and trigger automatic protective responses. Normally, this system works beautifully and life is preserved well into adulthood.
However, in some cases, this alarm system goes haywire. For example, some people are born with the inability to feel pain , a condition called the congenital insensitivity to pain . That condition is not a blessing, but a curse that leads to insurmountable body damage and a premature death. The nervous system can go haywire in other ways too. What happens if this alarm system is too sensitive? Now instead of feeling no pain, one is left to feel too muc...
Although Xyrem (sodium oxybate) failed to gain FDA approval for the treatment of fibromyalgia, it is sometimes prescribed off-label to treat the sleep problems that commonly accompany FM. Thus far, Xyrem only has FDA approval to reduce attacks of muscle weakness (cataplexy) and treat daytime sleepiness in patients with narcolepsy.
This week the FDA reminded both healthcare professionals and patients that the combined use of Xyrem with alcohol or central nervous system (CNS) depressant drugs can markedly impair consciousness and may lead to severe breathing problems (respiratory depression). The use of alcohol with Xyrem is a new contraindication added to the Xyrem label.
In addition to alcohol, medications that should be avoided when taking Xyrem include:
Sedating antidepressants or antipsychotics
The use of Xyrem along with these products or other CNS depressants increase...
Many of our moods depend on our nervous system. Too much or too little of the chemicals that speed things up or slow things down and the whole thing can go out of kilter. The basis of many of our medications is to correct these imbalances. In this Sharepost I’m taking a look at just a handful of the essential neurotransmitters and the way they work?
Glutamate and GABA can be thought of as mainstay neurotransmitters. They slog away in high concentrations within the brain where one (glutamate) is the throttle and the other (GABA) acts as the brake. Glutamate has an important role in learning and memory but too much and it can lead to agitation, impulsive behavior and even violence. GABA has the opposite effect. It increases our levels of tranquility by inhibiting too much nerve activity. Some of the most frequently used drugs for anxiety enhance the action of GABA.
Serotonin is all about serenity and hopefulness in moods. The latest generation of SSRI drugs, su...
