Out vets need this, my daughter just was diagnosed two weeks ago and was basically told Go home and learn how to die!! I think this has to stop. Money, as always, is the evil answer behind all this. I wonder if one of their families got a disease like this if they would get it.
I know the answer to that question. I asked Dr. Glass what he would do if he had ALS.

Donald Trump, bad science, and the vitamin company that went bust By Ike Swetlitz.Gallegos, 68, a retired psychologist, sat in an electric wheelchair in his brightly lit home southeast of Denver.
His illness, also called amyotrophic lateral sclerosis, or ALS, had left him unable to speak more than a couple of words without pausing to inhale, his chest heaving and neck cords bulging with each gulp.
His hands were curled into claws. His voice had weakened to a near whisper. He was still reeling from a respiratory attack that forced him to spend much of the weekend drawing oxygen from a ventilator.Part 1: ALS Canada Webinar Series: Update on ALS Clinical Trials
I get to feeling like I'm losing every day, and ALS is winning. Gallegos had two choices. He could allow the disease to take its course. Or he could pursue another option, newly legal, that would allow him to pick the time and place of his death. Under a law Colorado passed inhe had obtained a prescription for a cocktail of drugs that would put him to sleep, drop him into a coma, and, within an hour, stop his heart and breathing. The next steps were to call the pharmacy, have someone mix the drugs in a cup, and drink.
Thousands have ended their lives sincewhen it was first made legal in Oregon. On Friday, New Jersey became the eighth state to legalize medical aid in dying, and others are considering it. Advocates say the option gives patients more control over their fate, and relieves some of their anxiety over death. Opponents say giving people the ability to end their own lives is immoral, undercuts doctors and risks abuse.
In the middle are people like Gallegos. He embraced the option but spent his final weeks agonizing over it. Roughly a third of people who get prescriptions for end-of-life medications do not take them, according to states that track their use.Izone contract
As more states offer the option to terminally ill patients, thousands of Americans each year, along with their loved ones, are confronting this harrowing dilemma. Was it when he could no longer breathe, or eat, on his own? The drugs offered an escape, but he worried that ending his life was cowardly and unnatural.
The neurologist who diagnosed Gallegos with ALS in November cited research on average survival rates: Most patients lived from two-and-a-half to five years.
The news — following symptoms that began with difficulty writing certain numbers — felt like an ambush. Those afflicted gradually lose the ability to speak, swallow, control their bladder and bowels, and breathe.
Yes, I have a limp. When his denial subsided, he saw that he could use his remaining time to say goodbye to the people he loved, leave things in proper order for Karen Miller, his partner of two decades, and live the rest of his days in as dignified a way as possible.CNN An experimental treatment for the rapidly progressive disease ALS, or amyotrophic lateral sclerosishas been called potentially "game-changing.

The treatment, called tofersen, was found to slow the decline of muscular function associated with a genetic form of ALS in a study to be presented next week at the annual meeting of the American Academy of Neurology.
Timothy Miller, professor of neurology at Washington University in St. Louis and first author of the study, which has not been published. Tofersen is still in its developmental stages, and how much it could cost is not yet known. Stem cell study offers hope for ALS Specifically, the experimental treatment contains antisense oligonucleotidewhich targets a type of ALS, also known as Lou Gehrig's disease, caused by mutations on the SOD1 gene.
That was back in ," said Dr. He added that the treatment is administered as a spinal tap, during which antisense oligonucleotide is injected into spinal fluid. Battling the deadly disease ALS The patients were randomly assigned to receive either 20, 40, 60 or milligrams of the tofersen treatment or a placebo for 12 weeks. During that time, the researchers assessed the safety and efficacy of the treatment.
Overall, they found that the treatment was effective in reducing muscular decline in the patients assigned to receive doses of tofersen. Participants who got smaller doses showed less of a reduction. The researchers also found that the majority of side effects were mild or moderate, such as pain at the injection site and headaches, Miller said. Could this help treat ALS? It's a very modest effect, if any," Glass said.
As for the new treatment approach targeting a specific gene mutation, "we're in a new era of therapeutics for neurological disease," he said.
That's a huge leap forward. Get CNN Health's weekly newsletter. Catherine Lomen-Hoerth, neurologist and director of the ALS Center at the University of California, San Francisco Medical Centercalled the new study impressive in terms of its findings and the number of patients recruited to participate.October 29, There is currently no cure for amyotrophic lateral sclerosis ALS.
But new research could open up avenues for better diagnosis and more effective treatment. In ALS, those proteins collect in nerve cells in the brain and spinal cord, causing sloughs of them to die off.
This sweeping effect slowly paralyzes the patients. Hammell's lab, working closely with researchers from other leading institutions, recently published the findings in Cell Reports. Hammell's team tried to determine whether there were different types of ALS patients by studying the functions of the TDP protein and its links to retrotransposons, also known as " jumping genes ," an important part of this genetic puzzle.
The genes can randomly move from one spot of a chromosome to another.
ALS Insight Newsletter
They can also alter gene expression, a process in which the instructions from DNA are translated into functional activities in the cell. TDP is one of the proteins that keep jumping genes silent. But when TDP accumulates in clumps or aggregates in the nerve cells of ALS patients, it fails to silence the jumping genes.
Hammell's group found these telltale signs of TDP pathology, or abnormal characteristics, and elevated transposons in some ALS patient samples. To find some of those answers, the team studied gene expression patterns in the brain tissues of post-mortem patients with and without TDP pathology. They saw there was a de-silencing of jumping genes for the subset of patients with the most extensive TDP pathology.
The team now wants to confirm whether the jumping genes actually contribute to the toxicity of cells in ALS patients. The team speculates that high levels of these jumping genes might mimic a viral pathogen or other infection in the tissues.
If so, researchers may be able to directly target those genes with antiviral agents or other therapies.

The newest member is jplacit Mark all forums as read.Amyotrophic lateral sclerosis, or ALS, is an adult-onset neurodegenerative disease that causes paralysis and ultimately death when the nerves enervating the lungs cease to carry the signals needed for breathing. The disease has what is called a "focal onset," where paralysis starts with an arm or a leg and spreads throughout the body as motor neurons in the spinal cord and brain die off. Early diagnosis of the disease has not been possible because of a lack of known biomarkers indicative of ALS, but scientists believe that cellular changes within spinal neurons occur before symptoms are detectable, and these changes could serve as useful biomarkers that can aid in earlier diagnosis.
Now, researchers at the University of Illinois at Chicago have described unique populations of neurons and associated cells in the spinal cords of patients who died of ALS. When symptoms of ALS begin with the paralysis of an arm or a leg, it means that the disease has affected the motor neurons that enervate that arm or leg and which originate in a specific region along the spinal cord. For example, neurons that innervate the arm originate in the upper part of the spinal cord.
In ALS, where symptoms first appear in the arm, the motor neurons in the upper spine region die off.2003 f550 fuse diagram
Motor neurons above and below that region begin to die off next as the disease spreads up and down the spine, causing paralysis of other parts of the body. The researchers, led by Fei Song, associate professor of neurology and rehabilitation in the UIC College of Medicine, found that patients with focal-onset ALS had different types of neurons in areas of the spinal cord that are less affected by the disease compared with patients without neurological disorders.
They also found that spinal neurons in less affected regions of patients who died of focal-onset ALS were associated with cells called microglia and astrocytes.
They report their findings in the journal Neurobiology of Disease. So, new drug targets, especially ones that could be given in the earlier stages of the disease, are very much needed. Song had worked with Dr.
ALS research reveals new treatment approach
Ravits sees patients with ALS and runs a biorepository that includes nerve tissue from patients who died of ALS and consented to have their nerve tissue collected after death. Ravits published a paper in analyzing the expression of genes in spinal motor neurons taken from 12 patients whose ALS started focally compared with nerves of patients without neurological disorders.
Motor neurons were collected from less affected regions of the spinal cord where the tissue was assumed to be in the earlier stages of disease. While significant differences were found, Song wanted to reanalyze the genetic data using a new technique that could shed light on different cell types that may have been present in the samples collected by Ravits.
Song and colleague Fabien Dachet, a research specialist with bioinformatics expertise in the UIC department of neurology and rehabilitation, applied a novel bioinformatics analysis to the genetic data.
They found that in samples from patients with focal-onset ALS, there were different types of motor neurons compared with control samples from patients without neurological disease.
They also saw other cells called microglia and infiltrated macrophages associated with motor neurons from the ALS patients, where these cells were absent in similar samples from patients without neurological disease.

Explore further. DOI: Provided by University of Illinois at Chicago.On June 2,at the age of 37, baseball player Lou Gehrig succumbed to amyotrophic lateral sclerosis ALSa progressive muscle degeneration disease. Today, nearly 80 years following his death, scientists are still searching for the root cause -- and an effective treatment -- for the condition.
Now, scientists from Sanford Burnham Prebys have revealed that a protein called membralin plays a key role in ALS and identified a membralin-boosting gene therapy that extended the survival of mice with ALS-like symptoms. The study was published in the Journal of Clinical Investigations. However, researchers are still grappling with the basics: what causes ALS and what causes it to progress," says John Ravits, M.
ALS, often referred to as Lou Gehrig's disease, is caused by loss of motor neurons in the brain and spinal cord which leads to gradual muscle decline. Most people are between the ages of 40 and 70 when they are diagnosed; approximately 16, Americans have the condition, according to the ALS Association. For unknown reasons, military veterans are nearly twice as likely to be diagnosed with the disease.
There is no cure or effective treatment. Much about membralin, which was discovered inremains a mystery. Scientists know the protein is part of the cell's protein disposal machinery, called the endoplasmic reticulum-associated degradation system, and Xu's work previously revealed the protein's involvement in Alzheimer's disease.403 forbidden error fix
To better understand membralin's role in neurodegenerative diseases, he and his team created mice that lacked the protein in various brain cells, such as motor neurons, astrocytes, microglia, and oligodendrocytes.
This finding was especially unexpected -- and fortuitous -- as previous genome-wide association studies GWAS had never identified the membralin gene as a potential culprit in ALS. The scientists designed a series of experiments to further explore their findings, including analyzing several mouse models of ALS, studying astrocytes that lack the protein and analyzing spinal cord samples from people with and without ALS.
Their results showed that a neurotransmitter called glutamate accumulates in the region outside of membralin-deficient astrocytes. Excess glutamate is known to kill neurons, so this evidence provided a clue to the pathogenesis of ALS. The glutamate surplus was driven by downregulation of a glutamate transporter, called EAAT2.
Analysis of tissue samples from people with ALS confirmed that levels of membralin and the EAAT2 transporter are strongly correlated and both reduced in human disease. As part of the study the scientists also designed an adeno-associated virus AAV that can elevate membralin levels. ALS mice treated with the membralin-boosting AAV lived nearly two weeks longer than mice without the treatment -- indicating that boosting membralin or associated proteins holds promise as a potential therapeutic approach.
Next, the scientists plan to investigate whether this same mechanism -- impaired EAAT2 expression and glutamate overexpression -- also occurs in Alzheimer's disease, another disorder in great need of an effective treatment.
