Dementia is a progressive neurological disorder that can be caused due to Alzheimer's disease, alcohol abuse, severe depression or substance abuse. It is a highly debilitating condition that impairs a person's ability to think and reason. It also affects a person's ability to communicate with people. In addition, the person will display significant changes in his or her personality, poor judgment and disorientation.
It is definitely not easy to see your loved one, who was once vibrant and fun-loving, being afflicted with dementia. Invariably, one of the most common questions is how long does a person live with dementia. No one wants to see their loved one suffer with this debilitating condition. Unfortunately, there is no fixed answer to this. It varies from person to person depending on the stage of the disease, the overall health condition of the person, and the cause of the dementia.
When the dementia is on account of Alzheimer's disease, the lifespan of the person depends on how bad the Alzheimer's disease is. If it is in an advanced stage, then the person may survive just a couple of months before the body is afflicted by some infection and the person succumbs to it. If the Alzheimer's disease is in the early stages, the person will survive for about 4 to 4.5 years with dementia.
It has been seen that women tend to survive longer with dementia compared to men. In general, men survive for up to 4.1 years after Alzheimer's disease has been diagnosed, while women tend to survive up to 4.5 years after a confirmed diagnosis.
If dementia is caused due to vascular dementia, then the survivability of the person is different. Vascular dementia causes the flow of blood to the brain to decrease, and how long a person survives with it will vary from one person to another depending on the stage of the dementia. In case vascular dementia results in multiple strokes, then the person's lifespan will reduce even further.
