According to a Dutch study published in the journal Neurology,people who have either low or high levels of haemoglobin,may have a higher risk of developing dementia, including Alzheimer’s ,as they get older.

The study included 12,305 people without dementia, with an average age of 65,divided into groups according to haemoglobin levels.During an average follow up of 12 years, people with anaemia were found 41% more likely to develop Alzheimer’s and 34% more likely to develop any type of dementia.Those with higher levels were found 20% more likely to develop dementia, than the middle reading group.

The results remained the same even after accounting for other risk factors of dementia, including smoking, high blood pressure, high cholesterol and alcohol intake.
