“Key Marijuana Compound Beats Current Alzheimer’s Drugs in Test-Tube Study.
THC, the key compound in marijuana, may also be the key to new drugs for Alzheimer’s disease.”While we are certainly not advocating the use of illegal drugs, these findings offer convincing evidence that THC possesses remarkable inhibitory qualities, especially when compared to [Alzheimer’s drugs] currently available to patients,” Janda says in a news release.

“Although our study is far from final, it does show that there is a previously unrecognized molecular mechanism through which THC may directly affect the progression of Alzheimer’s disease.”

“THC and its analogs may provide an improved [treatment for] both the symptoms and progression of Alzheimer’s disease,” the researchers conclude”

“Active ingredient in pot may help preserve brain function.

Good news for aging hippies: smoking pot may stave off Alzheimer’s disease.

New research shows that the active ingredient in marijuana may prevent the formation of deposits in the brain associated with the degenerative disease.

Researchers at the Scripps Research Institute in California found that marijuana’s active ingredient, delta-9-tetrahydrocannabinol, or THC, can prevent an enzyme called acetylcholinesterase from accelerating the formation of “Alzheimer plaques” in the brain more effectively than commercially marketed drugs.

THC is also more effective at blocking clumps of protein that can inhibit memory and cognition in Alzheimer’s patients, the researchers reported in the journal Molecular Pharmaceutics.

The researchers said their discovery could lead to more effective drug treatment for Alzheimer’s, the leading cause of dementia among the elderly.

Those afflicted with Alzheimer’s suffer from memory loss, impaired decision-making, and diminished language and movement skills. The ultimate cause of the disease is unknown, though it is believed to be hereditary.

Marijuana is used to relieve glaucoma and can help reduce side effects from cancer and AIDS treatment.”

“THC, the key compound in marijuana, may also be the key to new drugs for Alzheimer’s disease. That’s because the marijuana compound blocks the formation of brain-clogging Alzheimer’s plaques better than current Alzheimer’s drugs….
 these findings offer convincing evidence that THC possesses remarkable inhibitory qualities, especially when compared to [Alzheimer’s drugs] currently available to patients,” Janda says in a news release.

“Although our study is far from final, it does show that there is a previously unrecognized molecular mechanism through which THC may directly affect the progression of Alzheimer’s disease.”

Janda’s team found that THC blocks an enzyme called acetylcholinesterase, which speeds the formation of amyloid plaque in the brains of people with Alzheimer’s disease.

The Alzheimer’s drugs Aricept and Cognex work by blocking acetylcholinesterase. When tested at double the concentration of THC, Aricept blocked plaque formation only 22 percent as well as THC, and Cognex blocked plaque formation only 7 percent as well as THC.

“THC and its analogs may provide an improved [treatment for] both the symptoms and progression of Alzheimer’s disease,” the researchers conclude.”

“New clues about Alzheimer’s disease have emerged from a Spanish study of marijuana. The drug’s active ingredients — cannabinoids — help prevent brain problems seen in Alzheimer’s, say the scientists. 

The new study didn’t test cannabinoids on people living with Alzheimer’s disease. Instead, the researchers focused on human brain tissue samples and conducted cannabinoid experiments on rats. 

The findings showed that “cannabinoids work both to prevent inflammation and to protect the brain,” says researcher Maria de Ceballos in a news release. That “may set the stage for [cannabinoids’] use as a therapeutic approach for [Alzheimer’s disease].””

“New evidence from animal models suggests marijuana may contain compounds that slow the memory loss associated with Alzheimer’s disease. Older rats treated with a synthetic chemical similar to marijuana significantly improved their ability to navigate a maze. Researchers believe the strong anti-inflammatory effects of marijuana slow Alzheimer’s progression.”

“The link between chronic inflammation and the progression of Alzheimer’s is compelling, said Gary Wenk, a study co-author and a professor of psychology at Ohio State University.

“Inflammation in the brain is part of aging,” Wenk said. “It happens to almost all of us as we age. But in some cases, this inflammation gets out of hand and causes serious damage.”

Treatment with a synthetic compound similar to marijuana reduced inflammation in older rats in addition to making the animals “smarter,” said Wenk, who is also a professor of neuroscience and molecular virology, immunology and medical genetics.

“The compound substantially improved the memories of the older rats,” he said. “These animals were able to hold on to key details of a specific task. Untreated older rats, on the other hand, were not.”

The researchers presented their findings at the annual Society for Neuroscience meeting.

Evidence suggests that people who regularly smoked marijuana in the 1960s and 1970s rarely develop Alzheimer’s disease, said Wenk, adding that researchers are eager to develop a drug with the anti-inflammatory properties of marijuana, but without the drug’s psychoactive effects.”

Hope for cannabis-based drug for Alzheimer’s

“A compound derived from marijuana might one day help fight the memory loss associated with Alzheimer’s disease, a new study suggests.

“Researchers have shown that a synthetic drug similar to cannabis can help older rats perform better on a spatial memory task.

Over a period of three weeks, Gary Wenk at Ohio State University in Columbus, US, and colleagues injected the brains of young and old rats with an inflammatory molecule that created an immune response in the animals’ brains which mimics that seen in Alzheimer’s patients.

During the same period the researchers also injected some of the rats with a synthetic drug similar to cannabis, called WIN-55212-2, which stimulates the brain receptors that normally respond to cannabis compounds.

The rats that received WIN-55212-2 in both age groups found the platform faster than their control counterparts. However, the difference between the treated and untreated animals’ performance was greatest among the older rats. The brains of rats receiving the synthetic drug also showed less sign of inflammation.

The results are impressive particularly because of the low dose of drug used in the experiment, comments Ken Mackie at the University of Washington in Seattle, US, who was not involved in the study.

“They gave them a relatively low dose, even for a rat.” Mackie says that this aspect of the study makes the prospect of developing a similar treatment for humans with Alzheimer’s disease “more promising”.

Wenk cautions, however, that WIN-55212-2 still causes psychoactive effects similar to cannabis, and as such is not yet a candidate for human use. Researchers are currently trying to develop a similar drug that could control inflammation in the brain without a concomitant high.”

Scientists are high on idea that marijuana reduces memory impairment

“The more research they do, the more evidence Ohio State University scientists find that specific elements of marijuana can be good for the aging brain by reducing inflammation there and possibly even stimulating the formation of new brain cells.

The research suggests that the development of a legal drug that contains certain properties similar to those in marijuana might help prevent or delay the onset of Alzheimer’s disease. Though the exact cause of Alzheimer’s remains unknown, chronic inflammation in the brain is believed to contribute to memory impairment.

Any new drug’s properties would resemble those of tetrahydrocannabinol, or THC, the main psychoactive substance in the cannabis plant, but would not share its high-producing effects.

.”Could people smoke marijuana to prevent Alzheimer’s disease if the disease is in their family? We’re not saying that, but it might actually work. What we are saying is it appears that a safe, legal substance that mimics those important properties of marijuana can work on receptors in the brain to prevent memory impairments in aging. So that’s really hopeful,” Wenk said”

Medical Cannabis Helps ALS Patient Outlive her Own Doctors

“In April, Cathy Jordan sat on a panel at the Cannabis Therapeutics Conference in Arizona. Before taking the stage, she discussed the medical use of cannabis for ALS with Jahan Marcu, the Philadelphia Medical Marijuana Examiner.

Cathy Jordan first noticed something was wrong in summer of 1985 when she couldn’t pick things up. Her muscles weren’t responding. In 1986, she was diagnosed with ALS (Amyotrophic Lateral Sclerosis). ALS, also known as Lou Gehrig’s disease, is characterized by the death of motor neurons leading to loss of limb control, breathing, swallowing, speech and widespread cellular dysfunction. Most cases of ALS are sporadic; it is not a viral or autoimmune disease.

Most people start using a feeding tube because they are afraid of choking to death”, says Cathy.

In 1986, she was given 3 – 5 years to live according to her neurologist. Nearly 3 decades later, she is still alive and living with ALS.

“All my docs are retiring or dead. I’ve outlived 5 support groups and 4 neurologists,” said Cathy. This actually posed a problem for Cathy who lost her social security benefits because she lived passed her expiration date. The state of Florida said her ID and regular documentation wasn’t good enough to prove she was alive and to continue to receive benefits. She had to ask her neurologist to fill out paperwork to prove she was still alive.

Mrs. Jordan began using Cannabis from a Florida grower to treat her ALS in the late 80’s. “Donny Clark provided my medicine, grown in the Myakka River Valley…he was busted and sentenced to life in prison, and that strain of Cannabis was lost.”

“You know, they say the fountain of youth is in Florida. Maybe it was something in the soil that made this plant helps me…and I don’t understand why doctors wouldn’t study me. But I still would like to know why this is helping me.”

At first, doctors wouldn’t accept that marijuana could be responsible for Cathy’s extended life span. Other doctors thought that smoking anything would impair her lung function and even threatened to have this paralyzed women committed, simply based on the fact that she thought Cannabis was actually helping her.

“I visited a neurologist at Duke University. When I told him that I was smoking Cannabis, he didn’t know what to do with me. He was afraid. He wouldn’t even take my blood pressure because I was using an illegal drug.”

Cathy adds:

“I asked my docs if they would take a drug if it was neuroprotective, an antioxidant and an anti-inflammatory. They say ‘yes’ and ask me if I know of one. Cannabis, I tell them.”

Nearly three decades later, the science has caught up with this miracle patient. Scientists created a mouse with ALS, which was very exciting for Cathy. Research has shown that THC and other cannabinoids can benefit mice with ALS. The mounting evidence of cannabinoids halting the progression of ALS has started to change the attitudes of doctors and prominent researchers have recently called for ALS clinical trials with Cannabis or cannabinoids.

“They all agree today that I should smoke Cannabis,” says Cathy. “Twenty six years later, my original neurologist fought [successfully] to make sure Cannabis is legal for patients in Delaware.”

Researchers think Cannabis may help ALS patients relieving pain, spasticity, drooling, appetite loss and has minimal drug-drug interactions and toxicity.

“There are ALS patients associations that fight for the right of patients to die with dignity. But what about my right to life?” asks Cathy. “Keeping my medicine illegal removes my right to life.””

Cathy Jordan’s Story

 

Cannabinoid Treatments: Amyotrophic Lateral Sclerosis (ALS)

Posted on by

“Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a fatal neurodegenerative disorder that is characterized by the selective loss of motor neurons in the spinal cord, brain stem, and motor cortex. An estimated 30,000 Americans are living with ALS, which often arises spontaneously and afflicts otherwise healthy adults. More than half of ALS patients die within 2.5 years following the onset of symptoms.

A review of the scientific literature reveals an absence of clinical trials investigating the use of cannabinoids for ALS treatment. However, recent preclinical findings indicate that cannabinoids can delay ALS progression, lending support to anecdotal reports by patients that cannabinoids may be efficacious in moderating the disease’s development and in alleviating certain ALS-related symptoms such as pain, appetite loss, depression and drooling.

Writing in the March 2004 issue of the journal Amyotrophic Lateral Sclerosis & Other Motor Neuron Disorders, investigators at the California Pacific Medical Center in San Francisco reported that the administration of THC both before and after the onset of ALS symptoms staved disease progression and prolonged survival in animals compared to untreated controls.

Additional trials in animal models of ALS have shown that the administration of other naturally occurring and synthetic cannabinoids can also moderate ALS progression but not necessarily impact survival. One recent study demonstrated that blocking the CB1 cannabinoid receptor did extend life span in an ALS mouse model, suggesting that cannabinoids’ beneficial effects on ALS may be mediated by non-CB1 receptor mechanisms.

As a result, experts are calling for clinical trials to assess cannabinoids for the treatment of ALS. Writing in the American Journal of Hospice & Palliative Medicine in 2010, a team of investigators reported, “Based on the currently available scientific data, it is reasonable to think that cannabis might significantly slow the progression of ALS, potentially extending life expectancy and substantially reducing the overall burden of the disease.” They concluded, “There is an overwhelming amount of preclinical and clinical evidence to warrant initiating a multicenter randomized, double-blind, placebo-controlled trial of cannabis as a disease-modifying compound in ALS.”
