9. Stroke
Consuming aspartame can also increase your risk of having a stroke. This makes sense when you consider that it also increases your risk of developing heart disease. One study showed that within 24 hours of giving rats aspartame in liquid form it had already been turned into methanol. This can cause oxidative stress within the brain. When the brain becomes stressed it can cause a person to have a stroke.
As the brain is unable to properly respond to the needs of the body, it can cause all types of issues, including motor skill issues. Many people who suffer from a stroke never fully gain the use of some of their limbs back, typically on one side of the body. Not only can consuming aspartame cause strokes, it can also cause a person to have a seizure. Once again this is associated with how the chemical affects the brain.
