What is the average life span after diagnosis of Central Nervous System Vasculitis?

My mother has been recently diagnosed with CNSV (central nervous system vasculitis) and from the research we have done, there is little hope of her surviving past ten years from the time of diagnosis.

Unfortunetly form my understanding, it's one of those diseases where the the treatments are more fatal then the disease. But without them the disease will drag out longer and be more painful. The estimates I've seen are everything from 45 days to 8 years.  (+ info)

Does any know anything about central nervous system Lupus?

I have an 18 year old daughter was diagnosed with Lupus 2 1/2 years ago. Her family doctor has been treating the pain with medication. She recently had an episode where she passed out for nearly an hour. Her neurologist said something about central nervous system lupus. How serious is this type apart from the muscular-skeletal lupus? She hides her pain really well. She has been homebound from school because of her pain for the past 2 semesters. What kind of treatment is available for my baby?

Lupus can indeed affect the central nervous system. It is also important to make sure her passing out was a nervous system issue and not one of the lupus clotting disorders (antiphospholipid antibody syndrome).

If she is not under the care of a rheumatologist, please consider that. Most family doctors are not trained in the nuances and dangers of lupus. The neurologist, rheumatologist and family doctor need to be on the same page. That is not likely to happen unless you or your daughter take charge and make sure that ALL of her doctors have ALL of the information.

Some lupus patients also suffer from neuropathy. It sounds like your daughter might benefit by a thorough work up with a few specialists.

Best wishes.  (+ info)

What is central nervous system depression?

In several MSDS files I have had to look up over the course of my two semesters of organic chemistry, I have noticed some chemicals that can cause central nervous system depression. I was curious if anybody knew exactly what this was? (I have an idea but am not sure)

The CNS (spinal cord and brain) is impaired and basically depressed, or slowed down. For example, acidosis (when there is too much acid in the blood because of carbon dioxide) depresses the CNS. This can lead to coma or death. Alcohol and cocaine depress the CNS also. Sensory, motor, and cognitive processing are impaired. Your reaction time (reflexes) can be lengthened.  (+ info)

How does heroin affect the central nervous system?

How does heroin affect the nervous system, like memory, mental health etc. And what is the effect? Thank you!

Heroin Effects
Heroin effects the central nervous system by depressing it. Heroin depresses nerve transmission in sensory pathways of the spinal cord and brain that signal pain. This explains why heroin is such an effective pain killer. Heroin also inhibits brain centers controlling coughing, and breathing.

Heroin is exceedingly addictive, quickly producing tolerance and dependence. Although heroin is even more effective as a painkiller than morphine and codeine, it is so highly addictive that its use is illegal. Methadone is a synthetic opiate that is used to break addiction to heroin (and replace it with addiction to methadone).

Short Term Heroin Effects

Soon after injection (or inhalation), heroin crosses the blood-brain barrier. In the brain, heroin is converted to morphine and binds rapidly to opioid receptors. Abusers typically report feeling a surge of pleasurable sensation, a "rush." The intensity of the rush is a function of how much drug is taken and how rapidly the drug enters the brain and binds to the natural opioid receptors. Heroin is particularly addictive because it enters the brain so rapidly. With heroin, the rush is usually accompanied by a warm flushing of the skin, dry mouth, and a heavy feeling in the extremities, which may be accompanied by nausea, vomiting, and severe itching.

After the initial effects, abusers usually will be drowsy for several hours. Mental function is clouded by heroin's effect on the central nervous system. Cardiac function slows. Breathing is also severely slowed, sometimes to the point of death. Heroin overdose is a particular risk on the street, where the amount and purity of the drug cannot be accurately known.

* Analgesia (reduced pain)
* Brief euphoria (the "rush" or feeling of well-being)
* Nausea
* Sedation, drowsiness
* Reduced anxiety
* Hypothermia
* Reduced respiration; breathing difficulties
* Reduced coughing
* Death due to overdose - often the exact purity and content of the drug is not known to the user. An overdose can cause respiration problems and coma

Long Term Heroin Effects

One of the most detrimental long-term effects of heroin is addiction itself. Addiction is a characterized by compulsive drug seeking and use, and by neurochemical and molecular changes in the brain. Heroin also produces profound degrees of tolerance and physical dependence, which are also powerful motivating factors for compulsive use and abuse. As with abusers of any addictive drug, heroin abusers gradually spend more and more time and energy obtaining and using the drug. Once they are addicted, the heroin abusers' primary purpose in life becomes seeking and using drugs. The drugs literally change their brains.

* Tolerance: more and more drug is needed to produce the euphoria and other effects on behavior.
* Addiction: psychological and physiological need for heroin. People are driven to get more heroin and feel bad if they do not get it. People begin to crave heroin 4 to 6 hours after their last injection.
* Withdrawal: About 8-12 hours after their last heroin dose, addicts' eyes tear, they yawn and feel anxious and irritable. Excessive sweating, fever, stomach and muscle cramps, diarrhea and chills can follow several hours later. These withdrawal symptoms can continue for 1 to 3 days after the last dose and can last 7 to 10 days. In some cases, full recovery can take even longer.

Other Heroin Effects

Medical consequences of chronic heroin abuse include scarred and/or collapsed veins, bacterial infections of the blood vessels and heart valves, abscesses (boils) and other soft-tissue infections, and liver or kidney disease. Lung complications (including various types of pneumonia and tuberculosis) may result from the poor health condition of the abuser as well as from heroin's depressing effects on respiration. Many of the additives in street heroin may include substances that do not readily dissolve and result in clogging the blood vessels that lead to the lungs, liver, kidneys, or brain. This can cause infection or even death of small patches of cells in vital organs. Immune reactions to these or other contaminants can cause arthritis or other rheumatologic problems.

Of course, sharing of injection equipment or fluids can lead to some of the most severe consequences of heroin abuse-infections with hepatitis B and C, HIV, and a host of other blood-borne viruses, which drug abusers can then pass on to their sexual partners and children.

* HIV/AIDS - due to sharing of needles
* Poisoning - from the addition of toxin to the drug
* Hepatitis - liver damage
* Skin infections - from repeated intravenous injections
* Other bacterial and viral infections
* Increase risk of stroke
* Collapsed veins
* Lung infections

Can smoking marijuan cause damage to the central nervous system and impair coordination?

Can weed cause you to develop a permanent movement disorder, neurological disorder or nervous system disorder?

Absolutely!  (+ info)

How does the Central nervous system respond to lets say a ball being thrown at you?

The events coordinated by teh nervous system in response to this event, pathways of information flow, the regiosn of teh CNS involved, etc.

visual cortex preceives the event, message is sent to the arms to stretch and grab the ball through the spinal cord and preipheral skeletal muscle nerves, next thing you know, the ball is in your hands! good luck  (+ info)

Does the West Nile Virus attack the central nervous system?

i am researching a disease that attacks the central nervous system.
Right now i am just looking for options.
I checked Wikipedia, and i could not figure out whether it attacked the central nervous system.


This is a great site for what you need to know. And yes...it can develop into a CNS disease in advanced states.  (+ info)

What's the difference between the central and peripheral nervous system?

I'm having a hard time understanding the difference. Can someone give me a simple description on them.
Also, which system are you using when you move your hand away from a hot stove?
What are some examples for them both?

CNS is brain and spinal cord. PNS are the sensory and motor neurons. The PNS breaks down further into the autonomic and the sensory-somatic nervous system. The autonomic breaks down further into the sympathetic and parasympathetic nervous systems. It is very complex but to answer your question when you touch a hot stove sensory neurons (PNS) send a message to the brain (CNS) and the brain process that the hand is being injured and reacts by sending motor neurons (PNS) to tell the hand to pull away. Good Luck.  (+ info)

Does MS only attack the Central Nervous System?

I have been diagnosed with Sensory Neuropathy with no explination for its cause. I was wondering if Musltiple Sclerosis only attacks the central nervous system or does it also attack the peripheral nervous system as well?

MS is a central nervous system disease. It does not involve the peripheral nerves.  (+ info)

How do STD's affect the Central Nervous system?

i am doing a project for health, and i have to be an expert on how std's affect the CNS, central nervous system. like the brain and spinal cord etc

The most common one you can cite is how tertiary (late stage) syphilis destroys the brain. Look up the term "neurosyphilis."

Secondly there's a rare complication of genital herpes called herpes encephalitis. The virus causes an inflammation in the brain, which can be life-threatening. Look up "herpes encephalitis" for more info.  (+ info)
