Unwanted effects reported in at least two studies were nausea, elevated weakness, behavioral or mood changes, suicidal thoughts or hallucinations, fainting or dizziness symptoms, fatigue, and feelings of intoxication. There was one record of a seizure. Disposition adjustments and suicidal thoughts are of particular concern for people with MS, who are at an elevated risk for suicide or unhappiness. The scholarly studies showed the risk of serious psychological effects is about 1 %, or one in every 100 people. In general, medical marijuana is recommended as a treatment for use only when standard treatment hasn’t helped.. AAN review finds certain types of medical marijuana might help treat some symptoms of MS An assessment by the American Academy of Neurology of obtainable scientific research on the use of medical marijuana in mind diseases finds certain forms of medical marijuana can help deal with some symptoms of multiple sclerosis , but do not appear to be helpful in treating drug-induced motions in Parkinson's disease.When untreated mice inhaled ragweed extract, their lung area experienced an influx of eosinophils , a leap in inflammatory signaling molecules, a buildup of mucin and an increase in airway hyper-reactivity . Mice fed a dosage of aldose reductase inhibitor before inhaling ragweed extract, however, showed dramatically reduced levels of these components of the asthmatic response. Our hypothesis performed exactly as anticipated, with the experiments displaying that aldose reductase can be an essential enzyme in the transduction pathways that cause the transcription of the cytokines and chemokines known to act in asthma pathogenesis, Srivastava said.
