Vascular dementia is a medical term that describes mental problems that arise from an insufficient blood supply to the brain, according to Mayo Clinic. It covers problems related to mental processes such as reasoning, memory, planning and judgment.
One cause of vascular dementia is stroke, which hinders the blood flow to the brain by blocking an artery in the brain, as stated by Mayo Clinic. However, not all stroke patients develop vascular dementia. Disorders that hinder the blood flow to the brain by destroying blood vessels also cause vascular dementia. Hypertension, smoking, elevated cholesterol, diabetes and obesity predispose an individual to vascular dementia.
The symptoms of vascular dementia include confusion, memory problems, concentration and attention problems, and depression, reports Mayo Clinic. An individual with vascular dementia may also experience a frequent urge for urination and may not be able to control urine passage. The symptoms vary from one person to another depending on the location of the brain that is affected. Because a specific test for vascular dementia doesn't exist, the patient should record all the symptoms experienced before visiting a doctor for diagnosis and treatment. The treatment involves addressing the underlying causes, including blood sugar control, cholesterol reduction and blood pressure reduction.
