Dementia (dementia) is a general term for memory loss and other intellectual diseases that affect life. It is irreversible. Patients often get confused. Early symptoms include memory problems, changes in the way you speak (such as forgetting words) and personality changes. Other symptoms include decreased ability to solve problems, ability to learn new skills, and ability to make decisions. Dementia is associated with clear brain lesions, such as loss of brain cells, problems with neurons, links and neurotransmitters, especially in Alzheimer's disease.
Alzheimer's disease is the most common form of dementia. The progress of the disease is slow, and there is no way to treat the disease at present, but some drugs can control the symptoms of the disease.
Vascular dementia (VD) patients account for 10% of the population with memory loss. It usually appears three months after a stroke. The disease is related to changes in the brain. The patient's gait was abnormal, visual field was blocked, and the face drooped.
Mixed dementia (MD) is a mixture of Alzheimer's disease and vascular dementia. It accounts for 15% of people with memory loss.
Lewy body dementia accounts for 15% of the people with memory loss. It is the general name of two related clinical diagnosis diseases: Parkinson's disease dementia and dementia with Lewy bodies. Patients with Parkinson's disease who have been diagnosed with dementia within a year belong to dementia patients with Lewy body disease. People with dementia who develop Parkinson's disease a year later are those with Parkinson's disease. The symptoms of dementia patients with Lewy body disease include fluctuating attention and vigilance changes, hallucinations and so on. The symptoms of Parkinson's disease dementia patients include gait changes, walking stiffness, frequent falls, shaking, straight waist, expressionless face, drooling, etc.
