The word dementia is a term which describes a serious deterioration in mental functions, such a memory, language, orientation and judgement. The causes are still not fully understood.Types and causes of dementia:Alzheimer’s disease: is the most common cause of dementia. It is caused by nerve cells dying in certain areas of the brain. In addition to this, the connections between affected nerve cells deteriorate. As the disease progresses, it spreads and affects cells in other parts of the brain. The cause of the brain cells dying and the deterioration of the connectors is not fully known.Vascular dementia: is a form of dementia caused by damage to the brain through deprivation of oxygenated blood. Oxygenated blood is carried through the body and brain through arteries – deoxygenated is carried through veins. Arteries and veins make up part of the vascular system. When an organ is the body is deprived of blood, that organ (or part of it) will die. This is what happens to the brain in vascular dementia. The conditions which can cause these problems are high blood pressure, heart problems diabetes and high cholesterol. Leading a healthy lifestyle is important.Creutzfeldt-Jakob Disease (CJD): is a form of dementia caused by prion which is proteins found in mammals. When these proteins cluster together in the brain they cause brain cells to die. When these cells die they leave holes in the brain called spongiosis. The damage to the brain causes neurological difficulties and dementia.Biswanger’s disease: is a form of vascular dementia in which damage occurs to the blood vessels in the deep white...
