Scientist Find Possible Alzheimer’s Gene

There are scientists that have found a gene that might raise the chances of getting the most common kind of Alzheimer’s disease by 45 percent in people who inherit a certain form of the disease. The gene affects a brain cell’s ability to take in calcium. Hopefully, drugs can be made to fight this effect. Most people are over the age of 65 that are affected by the disease.

Only one gene, called CALHM1, has been found to affect the risks associated with people over the age of 65. There are many other genes that are being studied as having the possibility to affect the disease.

Common Causes of Strokes

Most strokes happen when clot blocks blood flow to the brain. Strokes can also happen when a blood vessel bursts in the brain. High blood pressure encourages strokes because it can cause a buildup of arterial plaque, which can cause blood clots.

Birth control pills and hormone therapy increases the risk of having a stroke. Hormone therapy for menopause symptoms has less estrogen than birth control pills but still increases the risk of stroke a little bit.

Sleep apnea is a condition that interrupts the breathing process while a person is asleep. It raises blood pressure and the risk of having a stroke.

Other things that increase the risk of stroke include blood clotting disorders and having migraines with auras. Auras are visual changes that happen before having a migraine.

The risk of having a stroke can be cut in half just by lowering high blood pressure and high cholesterol. If a female has high cholesterol, hypertension, obesity, or diabetes, then she should be very cautions when taking birth control pills so that she can lower the risk of having a stroke.
