Marijuana May Be Legitimate Treatment for Alzheimer’s Disease, Report Says

“Researchers at the Roskamp Institute in Florida recently published a study in the journal Molecular and Cellular Neuroscience revealing that cannabinoids could delay the effects of Alzheimer’s disease, and could quite plausibly terminate the disease entirely.”

“Corbin Bachmeier, Ph.D, lead researcher of the study, declared that Alzheimer’s disease is “the result of impaired Aβ [Amyloid-β protein] clearance from the brain”. According to this particular study, cannabinoids can resolve this problem, which makes it a prospective treatment.

Bachmeier’s examination determined that “modulation of the cannabinoid system was shown to reduce Aβ [Amyloid-β protein] brain levels and improve cognitive behavior in Alzheimer’s disease animal models.”

The study’s abstract states that the objective of the study was to “investigate the role of the cannabinoid system in the clearance of Aβ across the blood–brain barrier (BBB).”

For the first time in recorded history, the study in question establishes that the cannabinoid system does indeed play a role in the transit of Amyloid-β protein across the blood-brain barrier.

Bachmeier concluded that his discoveries “provide insight into the mechanism by which cannabinoid treatment reduces Aβ [Amyloid-β protein] burden in the AD [Alzheimer’s disease] brain and offer additional evidence on the utility of this pathway as a treatment for AD.”

This is good news for individuals suffering with this specific ailment and for their loved ones. Cannabinoids seem to be boundless in respect to the medicinal benefits they have to offer.”

Marijuana may block Alzheimer’s

“The active ingredient in marijuana may stall decline from Alzheimer’s disease, research suggests.” 

Brain

 

“Scientists showed a synthetic version of the compound may reduce inflammation associated with Alzheimer’s and thus help to prevent mental decline.

They hope the cannabinoid may be used to develop new drug therapies.”

Pot smoking may help relieve symptoms of MS – NBC News

“Smoking marijuana may improve some symptoms of multiple sclerosis, a new study suggests.

Patients with multiple sclerosis in the study had less muscle tightness, also called spasticity, and less pain after they smoked marijuana, compared with after they took a placebo…

More research is needed to confirm the findings and to investigate whether lower doses of marijuana may have similar benefits with fewer adverse effects, said study researcher Dr. Jody Corey-Bloom, professor of neurosciences and director of the Multiple Sclerosis Center at the University of California, San Diego.

The study is published today (May 14) in the Canadian Medical Association Journal.

Improved symptoms

Previous studies have suggested marijuana use may have benefits for MS patients, but most have investigated oral forms of the drug, including mouth sprays and capsules. In addition, most studies have asked patients to report changes in their symptoms, rather than having a researcher objectively assess them…

Participants were randomly assigned to receive treatment with a marijuana cigarette or a placebo cigarette, which did not contain delta-9-tetrahydrocannabinol (THC), the active ingredient of marijuana. Participants smoked a marijuana cigarette once a day for three consecutive days under the supervision of a researcher. Eleven days later, participants repeated the procedure, but this time, they switched treatment groups so that everyone received the marijuana cigarette and placebo at some point in the study. On average, participants smoked four puffs of their cigarettes at each session.

Shortly after each treatment session, the researchers assessed participants with a test specifically designed to measure spasticity.

After smoking marijuana, participants experienced a 30 percent reduction in spasticity, compared with when they smoked the placebo cigarette, Corey-Bloom said.”

Aylsham multiple sclerosis sufferer says cannabis-based drug ‘changed my life’

“A new cannabis-based licensed drug has transformed the life of multiple sclerosis (MS) sufferer Teresa Pointer from Aylsham.”

“Mrs Pointer, 42, spotted an advertisement in the EDP eight years ago, asking people to take part in treatment trials at the James Paget University Hospital, Gorleston, and she has not looked back.

Today, thanks to two daily sprays of Sativex into her mouth, Mrs Pointer can sleep at night, walk for longer – and she has got her sense of humour back.

“I got in touch with Dr Willy Notcutt at the James Paget and then started on a clinical trial of Sativex. It was the best decision I’ve ever made and it’s done so much for me. It really has given me my life back,” said Mrs Pointer, who lives with her husband and two daughters in Hungate Street.

She was diagnosed in 2004 with MS, a disease which affects nerves in the brain and spinal cord.

An increase in muscle tone, or “spasticity”, is a common symptom, causing involuntary muscle spasms, immobility, disturbed sleep, and pain.

Although MS is incurable, treatments and specialists can help sufferers manage their symptoms.

Within two weeks of starting the trial, Mrs Pointer, whose health problems forced her to retire from her job as an assistant cook at Aylsham’s Bure Valley School, began to notice an improvement.

“It doesn’t take any of the symptoms away but it relieves them,” she said. The drug relaxed her muscles, easing the pain, discomfort and spasms when her legs would “try and jump off the bed”, which stopped her sleeping.

“I had been getting so tetchy through lack of sleep. I was snappy and angry all the time. But, because it helped me sleep, I could laugh and smile again. I found the funnier side of life which I thought I’d lost forever.”

At a later point in the double-blind trial, which involved 18 local patients, Mrs Pointer, without her knowledge or that of the medical team, was given a placebo instead of Sativex. Her symptoms soon returned and she could not sleep.

After discussions with specialists, she was put back on the drug. “That night I slept like a baby again. The contrast was so stark,” she said.

Mrs Pointer said she had no previous experience of cannabis but Sativex only relaxed muscles, it did not generate the “high” sought by recreational drug users.

She also believes that, without the drug, she would be using her wheelchair far more often than she does at present as it relaxes her leg muscles enough to allow her to walk greater distances.

Dr Notcutt, research and development director at the James Paget, said Mrs Pointer’s participation in the trial had been invaluable.

He added: “The results of these studies are being used all across the world as doctors and others look at the potential value of this medicine. Teresa and others like her locally have been pioneers in a therapy that has a huge potential in many different areas. Without more volunteers to help us explore, medical research will only make very slow progress.”

■ Around 100,000 people in the UK have MS. It is normally diagnosed in people between the ages of 20 and 40, and affects almost three times as many women as men.

■ Sativex, in the form of a mouth spray, contains the principal extracts delta-9-tetrahydrocannabinol and cannabidiol – found in the leaf and flower of the cannabis plant, and is the first cannabinoid preparation to be licensed in the UK for use in the treatment of muscle spasms in MS.”

[Marihuana and cannobinoids as medicaments].

“Biological activity of cannabinoids is caused by binding to two cannabinoid receptors CB1 and CB2. Psychoactive is not only tetrahydrocannabinol (THC) but also: cannabidiol, cannabigerol or cannabichromen.

Formerly, the usefulness of hemp was assessed in the relation to temporary appeasement of the symptoms of some ailments as nausea or vomiting.

Present discoveries indicates that cannabis-based drugs has shown ability to alleviate of autoimmunological disorders such as: Multiple sclerosis (MS), Rheumatoid arthritis (RA) or inflammatory bowel disease.

Another studies indicates that cannabinoids play role in treatment of neurological disorders like Alzheimer disease or Amyotrophic lateral sclerosis (ALS) or even can reduce spreading of tumor cells.

Cannabinoids stand out high safety profile considering acute toxicity, it is low possibility of deadly overdosing and side-effects are comprise in range of tolerated side-effects of other medications.

In some countries marinol and nabilone are used as anti vomiting and nausea drug. First cannabis-based drug containg naturally occurring cannabinoids is Sativex. Sativex is delivered in an mucosal spray for patients suffering from spasticity in MS, pain relevant with cancer and neuropathic pain of various origin.

Cannabis side-effects varies and depend from several factors like administrated dose, rout of administration and present state of mind. After sudden break from long-lasting use, withdrawal symptoms can appear, although they entirely disappear after a week or two.”

Amphiregulin is a factor for resistance of glioma cells to cannabinoid-induced apoptosis.

“Gliomas, one of the most malignant forms of cancer, exhibit high resistance to conventional therapies. Identification of the molecular mechanisms responsible for this resistance is therefore of great interest to improve the efficacy of the treatments against these tumors. Delta9-Tetrahydrocannabinol (THC), the major active ingredient of marijuana, and other cannabinoids inhibit tumor growth in animal models of cancer, including glioma, an effect that relies, at least in part, on the ability of these compounds to induce apoptosis of tumor cells.

…we identified the epidermal growth factor receptor ligand amphiregulin as a candidate factor to mediate the resistance of glioma cells to cannabinoid treatment… in vivo silencing of amphiregulin rendered the resistant tumors xenografts sensitive to cannabinoid antitumoral action.

Amphiregulin expression was associated with increased extracellular signal-regulated kinase (ERK) activation, which mediated the resistance to THC by blunting the expression of p8 and TRB3-two genes involved in cannabinoid-induced apoptosis of glioma cells.

 Our findings therefore identify Amphirregulin as a factor for resistance of glioma cells to THC-induced apoptosis and contribute to unraveling the molecular bases underlying the emerging notion that targeted inhibition of the EGFR pathway can improve the efficacy of antitumoral therapies.”

…Altogether, our findings identify Mdk as a pivotal factor involved in the resistance of glioma cells to THC pro-autophagic and antitumoral action, and suggest that selective targeting of the Mdk/ALK axis could help to improve the efficacy of antitumoral therapies for gliomas.”

Marijuana Chemical May Fight Brain Cancer – CBSNews

“The active chemical in marijuana promotes the death of brain cancer cells by essentially helping them feed upon themselves, researchers in Spain report.

Guillermo Velasco and colleagues at Complutense University in Spain have found that the active ingredient in marijuana, THC, causes brain cancer cells to undergo a process called autophagy. Autophagy is the breakdown of a cell that occurs when the cell essentially self-digests.

The team discovered that cannabinoids such as THC had anticancer effects in mice with human brain cancer cells and people with brain tumors . When mice with the human brain cancer cells received the THC, the tumor growth shrank.

Two patients enrolled in a clinical trial received THC directly to the brain as an experimental treatment for recurrent glioblastoma multiforme , a highly aggressive brain tumor. Biopsies taken before and after treatment helped track their progress. After receiving the THC, there was evidence of increased autophagy activity.

The findings appear in the April 1 issue of the Journal of Clinical Investigation.

The patients did not have any toxic effects from the treatment. Previous studies of THC for the treatment of cancer have also found the therapy to be well tolerated, according to background information in journal article.

Study authors say their findings could lead to new strategies for preventing tumor growth.”
