I'm concerned that my mom may have Alzheimer's. What is the best way to determine what is causing the memory decline?
Although Alzheimer’s Disease is the most common form of dementia in the U.S., there are many reasons why someone’s memory can decline and some of these causes can be treated. A thorough evaluation by someone who specializes in memory impairment is the first step – this could be a neurologist, psychiatrist, or a geriatrician. The evaluation will include testing for delirium (acute confusion due to infection, medication, acute illness), depression (which is sometimes associated with poor memory), Vitamin B 12 deficiency, thyroid abnormality, metabolic abnormalities (abnormal glucose and calcium, kidney and liver failure), progression of chronic diseases (poor oxygenation due to lung disease, heart disease, anemia). Imaging the brain is often helpful in determining if there is a tumor, stroke, or increased intracranial pressure.
