Vascular dementia is the second most common cause of dementia after Alzheimer's disease. It is caused by damage to the brain by cerebrovascular disease graviola or cardiovascular - usually strokes by reducing blood flow to the brain.
It can result from genetic diseases, endocarditis (infection of the heart valves) or amyloid angiopathy (amyloid deposition occurs in the walls of small arteries and arteriorelor, causing cerebral hemorrhage). In many instances, vascular dementia can coexist with Alzheimer's disease.
Compared to people with Alzheimer's, those with vascular dementia maintain their personality and normal emotional response even in advanced stages of the disease. Those suffering from vascular dementia, graviola most often are agitated during the night and have problems that are found in people with stroke, such as depression and unconsciousness. There are several types of dementia, which vary in symptoms and causes:
Multi-infarct graviola dementia is due to the small number of strokes. This includes many affected areas, known as infarcts, together with other extensive lesions in the brain. Not all stroke causes of dementia, graviola but in some cases, one stroke is required to cause it. Dementia occurs more often when stroke occurs on the left side (hemisphere) of the brain and / or in the hippocampus (a structure of the brain important for memory).
Dementia with Lewy bodies is one of the most common types of progressive dementia. This type of dementia usually occurs graviola sporadically in people with no history in the family. In dementia with Lewy bodies, cells in the brain cortex and substantia nigra (another part of the brain) die. Many of the remaining nerve cells in the substantia nigra contain abnormal structures called Lewy bodies some.
Symptoms of dementia with Lewy bodies resemble graviola those of Alzheimer's disease and may include memory impairment, confusion and decreased judgment. Typical symptoms of this type of dementia, however, include visual hallucinations, walking with small steps and flexed posture and can vary in intensity from day to day. People suffering from this disease live about another 7 years after the onset of symptoms. This disease is not curable and treatment is only effective to relieve some of the symptoms.
Frontotemporal dementia or frontal lobe of the brain describes a group of diseases characterized by degeneration of nerve cells - especially those of frontal and temporal lobes. graviola Compared with Alzheimer's disease, frontal lobe dementia does not include deposition of amyloid, but there is another specific protein that is deposited in the brain. This disrupts normal brain activity and cause cell death.
Huntington's disease is hereditary anomaly is caused by a gene for a protein called huntingtin. Children of people with the disease have a 50% chance of inheriting it. Huntington's disease causes degeneration in many regions of the brain and spinal cord. Symptoms usually graviola appear around the age of 30-40 years, and life expectancy after diagnosis is 15 years. graviola Cognitive symptoms of the disease begin with minor personality changes such as irritability, anxiety, depression progresses to severe dementia. Many patients and psychotic behavior. Also brings Huntington chorea - involuntary arrhythmic movements of the body, muscle weakness and gait disturbance.
