Dementia refers to a decline in cognitive function. It may be caused by different injuries or illnesses that affect your brain functions. The condition would affect your behavior, judgment, language, thinking, or memory. Some dementias are chronic and progressive, meaning they tend to become worse over time. Others are reversible and treatable. Below is a list of 6 common types of dementia that you should know.
Vascular dementia is a common form of dementia. It occurs when there is a lack of blood flow to your brain. Aging is a major risk factor. The condition is also associated with a stroke or atherosclerotic disease. Symptoms tend to show up suddenly or slowly, depending on the underlying causes. In the early stages, disorientation and confusion are common. Over time, people with vascular dementia might have difficulty focusing for an extended period of time or completing tasks. Hallucinations and vision issues might occur as well.
