Alzheimer's disease is a neurological condition. It is characterized by cognitive decline and memory loss due to the death of brain cells. This disease starts off mild and gets worse as it progressively. Alzheimer's disease is a very common form type of dementia. Alzheimer's disease cannot be cured, but treatment can help reduce the symptoms of alzheimers.
Alzheimer's disease occurs when the brain cells start to die. The size of the brain shrinks to a great extent. The brain tissue has very few connections and nerve cells. A postmortem/autopsy can only show the tiny inclusions inside the nerve tissues. This is called tangles and plaques. Plaques are formed due to the build-up of a substance called beta-amyloid (amyloid plaques). The tangles of the brain neurons are formed due to the disintegration of a protein called tau. According to researchers, alzheimer's disease goes way beyond protein abnormalities. alzheimer's disease makes it difficult to recognize faces and objects. The most prominent sign includes problem-solving, judgment and reasoning. A form of dementia called vascular dementia is caused due to a traumatic incident such as stroke, is the most common type of dementia after alzheimer's disease.
