Marijuana Prevents Memory Loss in Alzheimer’s Disease
Scientists in one of the leading research centers in Madrid, found evidence that cannabis can prevent memory loss in patients with Alzheimer’s disease.
Their preliminary research has shown that THC – the main psychoactive component of marijuana – inhibits the activity of cells, causing damage to brain neurons.
The mechanism of memory loss in these patients is not completely understood, but presumably the problem is partly related to glial macrophages (microglia), which form a shell around the nerve cells of the brain. In Alzheimer’s disease activities of microglia gets out of control and harm neurons, destroying entire sections of the brain.
Meanwhile, the U.S. legislation impedes full-scale studies of clinical efficacy of marijuana. At the same time the UK government allowed a pharmaceutical firm to grow different varieties of cannabis with the aim of clinical trials received from their marijuana.
Marijuana and drugs out of Tetrahydrocannabinol successfully used to improve the condition of patients with cancer and AIDS. THC has been successfully used to combat nausea caused by the use of anticancer drugs this purpose it was approved by the U.S. Food and Drug Administration. In some countries (eg Holland and Canada), marijuana is used as a medicine for cancer patients, as an antiemetic used in chemotherapy.
At the same time, pharmacological studies do not show the benefits of hemp over other, more conventional antiemetic and analgesics. As a result, the appointment of hemp products is in the nature of exception, with individual intolerance of traditional medicines.
Scientists hope the cannabinoid may be used to developed new drug therapies.
