Coffee and neurological diseases
The general public thinks that drinking 200 mg of caffeine (about 2.5 cups of coffee) in one breath, or drinking no more than 400 mg of caffeine (5 cups) a day, is not harmful to the body, and has no effect on the alertness of the brain and nervous system. Health, concentration can help, and can reduce the risk of depression, as well as strengthening the effect of medication on headaches.
Long-term use of coffee or caffeine may prevent cognitive decline and reduce the risk of stroke, Parkinson’s disease, and Alzheimer’s disease, but may increase anxiety and disrupt sleep in some people.
In terms of epilepsy, the role of coffee is still controversial. In animal model studies, it was found that short-term use of caffeine will reduce the threshold of epilepsy and make seizures easier. On the contrary, in human studies, long-term use of coffee/caffeine has been found to reduce the risk of seizures. Reduces seizures and reduces brain damage in status epilepticus.
Kahweol protects nerve cells from damage, such as the neurotoxin 6-hydroxydopamine (6-OHDA), a neurotoxin that causes Parkinson's disease. Studies have found that cafestol can induce heme oxygenase-1 (heme oxygenase-1) through phosphatidylinositol 3-kinase (PI3K) and p38/Nrf2 pathways, and is derived from 6-hydroxyl 6-hydroxydopamine-derived oxidative stress to protect dopamine neurons.
Coffee reduces relative risk of Parkinson's disease through multiple mechanisms
Parkinson's disease (Parkinson's disease) is a neurodegenerative disease with an incidence second only to Alzheimer's disease. The etiology is still unknown, but it is related to the degeneration of brain cells in the substantia nigra, which cannot produce enough dopamine (dopamine).
Why do substantia nigra cells degenerate? It is still unclear, and it is speculated that it may be related to genetic, environmental or life factors, such as the abuse of antibiotics, heavy metal pollution, etc. Several recent studies have shown that drinking coffee can actually prevent Parkinson's disease.
60 to 80% of people with Parkinson's disease have constipation problems that begin 10 to 20 years before symptoms appear. In 2014, a team from the Department of Neurology of National Taiwan University Hospital analyzed 550,000 cases of Parkinson's disease in the health insurance database, and once again confirmed that people with constipation problems have a much higher chance of developing Parkinson's disease in the future than the average person, and the more severe the constipation, , the higher the probability.
