Alzheimer’s and Parkinson’s affect men and women differently


Research conducted by scientists at the University of Maryland (United States) and published in APL Bioengineering , reveals that men and women are affected differently by brain diseases such as Alzheimer’s and Parkinson’s , which is why researchers from this study urge the scientific community to remember those differences when researching treatments for these diseases.

Sex differences play a role in how patients respond to brain diseases , as well as multiple sclerosis, motor neuron disease, and other brain ailments. The changes are associated with the breakdown of the blood-brain barrier.

The research published has shown differences in blood – brain barrier (an edge cell that prevents the wrong type of molecules in the bloodstream from entering the brain and damaging) of men and women. That could influence known differences in the sexes, such as Alzheimer’s is more common in older women than in men, while Parkinson’s affects men more often and tends to do so more severely.
