Alzheimer’s disease is caused by the abnormal deposition of amyloid and tau proteins, thereby causing the death of brain cells. The earliest symptom of this disease is memory loss. As the disease worsens, patients may have difficulty determining places, calculating, and problems with language. This is often accompanied by changes in character or abnormal behavior. The medication that the patients take after they are diagnosed with Alzheimer’s improves their cognitive function, thereby slowing down the worsening of the disease. Unfortunately, a cure or medication that stops the disease from advancing has not been developed yet.
