Loss of inhibitions Delusions, such as believing something has been stolen Many important skills are not lost until very late in the disease. These include the ability to read, dance and sing, enjoy old music, engage in crafts and hobbies, tell stories, and reminisce.
Essentially, every person with AD has accumulations of amyloid plaques comprised of the toxic beta-amyloid protein and neurofibrillary tangles aggregates of the tau protein in the brain. The abnormal accumulation of plaques and tangles cause neuron cells to die, leading to dramatic shrinkage and cell loss affecting areas of the brain that are responsible for memories, thoughts, sensations, emotions, movements, and skills.
Scientists are conducting studies to learn more about plaques, tangles, and other features of AD. New technology has made it possible to visualize plaques and tangles by imaging the brains of living individuals.
It is likely that the causes include genetic, environmental, and lifestyle factors. These individuals have a mutation, or permanent change, in one of three genes that they inherited from a parent.
These mutations are autosomal dominant, meaning that inheriting the gene causes the disease. Only people who had a parent with ADAD are at risk to get this genetic form of the disease. Many genes have been identified that appear to affect risk for the disease.
The APOE gene has three forms: Carrying APOE e4, however, does not necessarily mean that a person will develop the disease.
Large-scale genetic research studies are searching for other genes that increase or decrease susceptibility to AD. Lifestyle Factors A nutritious diet, exercise, social engagement, and mentally stimulating pursuits can all help people stay healthy.
New research suggests that such healthy lifestyle choice also might reduce the risk of cognitive decline and AD. Scientists are investigating associations between cognitive decline and heart disease, high blood pressure, cholesterol, diabetes, and obesity, as well as lifestyle practices.
Understanding these relationships and testing them in clinical trials will help clarify the extent to which controlling chronic health conditions and adopting healthy lifestyle practices may lessen the incidence of AD.
Common Signs and Symptoms Memory loss significant enough to disrupt daily life and activities Difficulty planning or solving problems Challenges carrying out familiar tasks Confusion or disorientation to time or place Difficulty understanding visual images and spatial relationships New problems with speaking or writing Forgetting and misplacing things, while losing the ability to retrace steps Decreased or poor judgment Withdrawal from activities social, work, etc.
Changes in mood and personality Disease Progression Initially, short-term memory and the ability to learn new information are affected. These problems worsen consistently, often slowly. Problems may include difficulty with finding words and expressing ideas, getting lost, difficulty handling money and paying bills, taking longer to complete normal daily tasks, and poor judgment.
Long-term memory, however, remains relatively intact at this stage. Driving becomes hazardous and should be stopped. People are often first diagnosed in this stage. As the disease progresses, reasoning, visual-spatial skills, planning and organization, sensory processing, and conscious thought become increasingly affected.Alzheimers Disease And Other Cognitive Disorders Cancer Chronic Obstructive Pulmonary Disease Colds And Flu Crohns Disease / Irritable Bowel Diabetes Epilepsy Heart Disease High Blood Pressure Mind Changing Brain Changing Mind.
