Coffee and neurological diseases

The general public believes 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, will not harm the body, and it will affect the alertness and Healthy, focused attention can help, and can reduce the risk of depression, and enhance the effects of medications for headaches, among other things.

Long-term consumption 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. Studies in animal models have found that short-term use of caffeine can lower the threshold of epilepsy and make seizures easier. On the contrary, long-term use of coffee/caffeine has been found in human studies. Reduces seizures and reduces brain damage in status epilepticus.

Caffeine alcohol (kahweol) can protect nerve cells from being damaged, for example, it can protect the neurotoxin 6-hydroxydopamine (6-hydroxydopamine; 6-OHDA) neurons related to Parkinson's disease from death. Studies have found that coffee beans can induce heme oxygenase-1 (heme oxygenase-1) through phosphatidylinositol 3-kinase (phosphatidylinositol 3-kinase; PI3K) and p38/Nrf2 pathways, and through 6-hydroxy derivatization Oxidative stress (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 rate second only to Alzheimer's disease. The cause is still unknown, but it is related to the inability to produce enough dopamine due to the degeneration of brain cells in the substantia nigra of the brain.

Why do substantia nigra cells degenerate? It is not clear at present, and it is speculated that it may be related to genes, environment or life factors, such as abuse of antibiotics, heavy metal pollution and so on. Several recent studies have shown that drinking coffee can prevent Parkinson's disease.

60-80% of patients with Parkinson's disease have constipation problem, and it starts as early as 10-20 years before symptoms appear. In 2014, the team of the Department of Neurology of National Taiwan University Hospital analyzed 550,000 cases of Parkinson's disease in the national health insurance database, and once again confirmed that people with constipation have a much higher probability of developing Parkinson's disease in the future than ordinary people, and the more severe the constipation , the higher the probability.

Study: Coffee helps prevent Alzheimer’s, Parkinson’s! Which is better: dark roast or light roast?

Coffee helps prevent Alzheimer's

A new study recently found that a cup of coffee in the morning not only lifts the spirits, but also protects against Alzheimer’s and Parkinson’s disease. Researchers at the Dolan-Doklopil Brain Institute found that phenylindanes, a chemical breakdown product of chlorogenic acid lactones in roasted coffee, inhibits the growth of Tau proteins and beta amyloid plaques, two proteins associated with increased risk of two diseases in the brain.

Regular Caffeine Intake May Help Prevent Dementia

According to Alzheimer’s and Dementia Weekly, Dr. Donald Weaver, co-director of the Crumbill Brain Institute, noted that coffee consumption appears to be associated with a reduced risk of Alzheimer’s and Parkinson’s disease, and they want to investigate what the cause is, what compounds are involved, and how it affects age-related cognitive decline.

Other studies have found that regular caffeine intake may help prevent dementia, AARP said. A study published in the Journal of Alzheimer’s Disease, which looked at people aged 65 to 84, showed that people who drank one to two cups of coffee a day were less likely to have mild cognitive impairment than those who never drank coffee. The American Association of Retired Persons pointed out that similar studies have found that coffee can even prevent Parkinson’s disease.

Dark-roasted coffee is more protective than light-roasted coffee

However, Canadian researchers have ruled out caffeine as a source of brain protection because even decaffeinated roasted coffee is beneficial in preventing dementia. The team determined that phenyl lindane, obtained through roasted coffee, is a beneficial compound that inhibits the aggregation of Tau and beta amyloid proteins in the brain associated with Alzheimer’s and Parkinson’s diseases.

The researchers also found that dark-roasted coffee, which contains more phenyl lindane, was more protective than light-roasted coffee, and the next step in the study is to measure how these compounds get into the bloodstream and cross the blood-brain barrier, and the good news is that phenyl lindane is a natural compound that has medicinal advantages over synthetic products. Dr. Weaver said that before coffee can be used to treat Alzheimer’s or Parkinson’s, more research is needed.
