Levels of antioxidants, vitamin C and beta-carotene are lowered in people with dementia.

Based on the health data of 74 people with dementia and 158 without cognitive impairment, German researchers analyzed serum levels of vitamin C, vitamin E, beta-carotene, lycopene and coenzyme Q10.

The volunteers are between 65-90 years old. They are subjected to neuropsychiatric tests, including various answers to questions related to their lifestyle. Blood samples and body mass index (BMI) were taken.

The results showed that the concentration of vitamin C and beta-carotene in the blood of participants diagnosed with mild dementia was significantly lower than in the control group.

There was no significant difference in the two groups regarding the levels of vitamin E, lycopene and coenzyme Q10.



Increasing the consumption of fruits and vegetables rich in vitamin C and beta-carotene, such as apricots, carrots, spinach can reduce the risk of dementia, according to the research team.


Dementia is a neurological disease characterized by cognitive impairment, lack of concentration, distraction and more.

Alzheimer's disease has a serious deterioration in cognitive abilities. It is characterized by the accumulation of amyloid-beta plaques in nerve cells.

Oxidative stress is also considered to be one of the presumed causes of the disease. It can be reduced with the help of antioxidants.

The results of the study were published in the journal Alzheimer's Disease .
