Vascular dementia in the elderly

All dementias related to cerebrovascular factors are collectively referred to as cerebrovascular dementia. First of all, it must be pointed out that dementia actually refers to the decline of brain function, especially the comprehensive decline of intelligence-related functions, and the syndrome to a certain extent. It usually includes a series of symptoms and signs such as memory, cognition, mood and behavior, and lasts for months or more. Vascular factors mainly refer to the blood vessels in the brain, namely the two major systems of the carotid artery and the vertebrobasilar artery. It can be the lesions of these blood vessels themselves, or the lesions of extracranial blood vessels and the heart, which indirectly affect the blood vessels in the brain. Insufficient blood supply causes the ischemia and hypoxic changes in the brain tissue, and eventually causes the brain function to decline.
