Alzheimer’s disease (AD) is a progressive neurologic disorder that leads to the death of brain cells. People with this condition usually exhibit mild memory loss, impaired judgment, and vision (spatial) issues during the initial stages, but the symptoms gradually worsen over time.
Reactive oxygen species (ROS) are highly reactive molecules and free radicals formed as a natural byproduct of oxygen metabolism. These molecules, which are present at low levels in normal cells, play a vital role in maintaining healthy redox processes and ensuring proper function in the cells. However, an overproduction of ROS may cause oxidative stress, cellular damage, and DNA damage, which may lead to several physiological and pathological conditions.
