What is Lekeuma?

Leukoaraiosis is a term that describes changes to the white matter of the brain. The word is derived from Greek, where leukos means white, and araios means rare or thin. Leukoaraiosis refers to a thinning or rarefaction of the white matter, which is the tissue that connects different parts of the brain and spinal cord.

On brain imaging, such as magnetic resonance imaging (MRI), leukoaraiosis is typically seen as areas of decreased signal intensity in the white matter. These changes are often more pronounced in older individuals and are associated with a number of conditions, including:

1. Aging: Leukoaraiosis is a common finding in the elderly, and its prevalence increases with advancing age.

2. Hypertension: High blood pressure is a major risk factor for leukoaraiosis. Hypertension can damage the small blood vessels in the brain, leading to changes in the white matter.

3. Diabetes: Diabetes is another risk factor for leukoaraiosis. High blood sugar levels can damage the blood vessels and nerves in the brain, leading to white matter changes.

4. Heart disease: People with coronary artery disease or other types of heart disease are more likely to develop leukoaraiosis. Heart disease can reduce blood flow to the brain, which can damage the white matter.

5. Smoking: Smoking is a risk factor for leukoaraiosis. The chemicals in cigarette smoke can damage the blood vessels and nerves in the brain, leading to white matter changes.

6. Obesity: Obesity is associated with an increased risk of leukoaraiosis. Obesity can lead to high blood pressure, diabetes, and other conditions that increase the risk of leukoaraiosis.

7. Genetic factors: Some people may be more likely to develop leukoaraiosis due to their genetic makeup.

In most cases, leukoaraiosis is not associated with any symptoms. However, in some cases, it can be a sign of more serious underlying conditions, such as stroke or dementia. If you have concerns about leukoaraiosis, it is important to talk to your doctor for further evaluation.
