Cancer does not protect against Alzheimer's disease

A new study contradicts the belief that cancer protects against Alzheimer's disease

Despite the claim that cancer patients are less likely to develop Alzheimer's disease, researchers led by scientists from the Institute of Oncology at the University of Utah, found a grim explanation. Many patients do not live long enough to get sick from this disease.

"Diagnosis of age-related diseases such as Alzheimer's disease, depends on whether the patient will live to the age when he can catch this disease," explains lead author Heidi Hanson, a research fellow of the Institute of Oncology, of family and preventive medicine . Doctor and her colleagues examined data from patients with pancreatic cancer. The average age at death is 73 years, the same as Alzheimer's disease is usually diagnosed.

The researchers conducted their own assessment, examining data 92245 people with cancer and without it. The group was aged 65 to 79 years, there was no information about dementia. Unlike previous tests, statistics have shown that cancer patients do not have protection against Alzheimer's disease due to the high mortality rate.

"These findings call into question the relationship between the protective function of cancer and Alzheimer's disease. If we talk about the diseases associated with aging, we need to consider the question of how other chronic diseases affect this," says Hanson.
