What is the usual age range of onset for multi-infarct dementia?
MID, which typically begins between the ages of 60 and 75, affects men more often than women. Because the symptoms of MID are so similar to Alzheimer’s disease, it can be difficult for a doctor to make a firm diagnosis.
How does multi-infarct dementia typically progress?
Vascular dementia usually progresses gradually in a step-wise fashion in which a person’s abilities deteriorate after a stroke, and then stabilise until the next stroke. If further strokes do not occur, the abilities of people with Vascular dementia may not continue to decline, or in some cases, may improve.
Is multi-infarct dementia the same as Alzheimer’s?
Because symptoms of multi-infarct dementia can develop in stages, they can be easily confused with Alzheimer’s disease. But very often forms of vascular dementia do occur with Alzheimer’s, and some research suggests that multi-infarct dementia may cause Alzheimer’s disease or lead to its progression.
What is multifocal dementia?
Multi-infarct dementia (MID) is a type of vascular dementia. It occurs when a series of small strokes causes a loss of brain function. A stroke, or brain infarct, occurs when the blood flow to any part of the brain is interrupted or blocked.
Is Binswanger disease hereditary?
Although Binswanger’s disease is not considered an inherited condition, genetics may play a role in many of the conditions and risk factors that are associated with the disease (i.e. atherosclerosis, blood clots).
What causes Binswanger disease?
Binswanger disease is caused by arteriosclerosis, thromboembolism and other diseases that obstruct blood vessels that supply the deep structures of the brain. Hypertension, smoking, hypercholesterolemia, heart disease and diabetes mellitus are risk factors for Binswanger disease.
What causes chronic infarcts in the brain?
A cerebral infarction is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). It is caused by disrupted blood supply (ischemia) and restricted oxygen supply (hypoxia), most commonly due to thromboembolism, and manifests clinically as ischemic stroke.
What is an infarct and what causes it?
Infarction is tissue death or necrosis due to inadequate blood supply to the affected area. It may be caused by artery blockage, rupture, mechanical compression, or vasoconstriction.
What is Binswanger dementia?
Binswanger’s disease (BD), also called subcortical vascular dementia, is a type of dementia caused by widespread, microscopic areas of damage to the deep layers of white matter in the brain.
What are the symptoms of Binswanger’s disease?
Most affected people experience progressive memory loss and deterioration of intellectual abilities (dementia); urinary urgency or incontinence; and an abnormally slow, unsteady gait (style of walking). While there is no cure, the progression of Binswanger’s disease can be slowed with healthy lifestyle choices.
