Do you know your stroke risk? Some factors are out of your control, like family history. But you can control some, including diet and physical activity. Now is the time to take charge of your health. The changes you make now could impact what happens later. Stroke Risk Factors You Can Control, Treat and Improve Keep your stroke risks low with regular checkups and treatment for these conditions if you have them.

Stroke Risk Factors That Are Not Within Your Control You can't control some risk factors, but knowing that they exist may help motivate you to work harder on the ones you can change.

Additional Factors That May Be Linked to Higher Stroke Risks Whether your risks are related to changeable factors or are primarily outside of your control, you can benefit your heart and your brain with healthy lifestyle choices. The primary pathophysiology of stoke is an underlying heart or blood vessel disease. The secondary manifestations in the brain are the result of one or more of these underlying diseases or risk factors.

The primary pathologies include hypertension, atherosclerosis leading to coronary artery disease, dyslipidemia, heart disease, and hyperlipidemia.

Hypertension and Stroke: Pathophysiology and Management

The two types of stroke that result from these disease states are ischemic and hemorrhagic strokes. Definitions Stroke A stroke apoplexy is the sudden onset of weakness, numbness, paralysis, slurred speech, aphasia, problems with vision and other manifestations of a sudden interruption of blood flow to a particular area of the brain.

Causes of Stroke The primary pathophysiology of stoke is an underlying heart or blood vessel disease. Non-reducable Risk Factors The possibilities of a stroke occurring increases with age. For every decade 10 years over the age of 55, the possibility of a stroke occurring doubles. A patient that is 75 years of age has four times the risk of having a stroke compared to someone who is 55 years old.
