In addition to a general physical exam, your doctor will likely conduct question-and-answer tests to judge your memory and other thinking skills. He or she may also order blood tests, brain-imaging scans and other tests that can help identify reversible causes of memory problems and dementia-like symptoms.
At your doctor visit, he or she can perform tests and assessments, which may include a brain scan, to help determine the source of memory problems. Your doctor may also recommend you see a neurologist, a doctor who specializes in treating diseases of the brain and nervous system.
Some of the most common blood tests ordered as part of a diagnostic evaluation for someone with changes in thinking or memory include: CBC (complete blood count), CMP (comprehensive metabolic panel), TSH (thyroid stimulating hormone), vitamin B12, RPR (rapid plasma reagin), HIV (human immunodeficiency virus).
People with symptoms of dementia are given tests to check their mental abilities, such as memory or thinking. These tests are known as cognitive assessments, and may be done initially by a GP. There are several different tests. A common one used by GPs is the General Practitioner Assessment of Cognition (GPCOG).
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
These exams can determine if you are showing signs that line up with the symptoms of dementia. Once your doctor has a combination of test results, along with your detailed medical history, they should have the evidence needed to give you an official diagnosis.
Age-related memory loss and dementia are very different conditions, though they may share some overlap in symptoms. However, normal forgetfulness is often caused by lack of focus and it never progresses into serious territory. Dementia, on the other hand, will get worse over time.
Although there are many causes of dementia -- including blood vessel disease, drug or alcohol abuse, or other causes of damage to the brain -- the most common and familiar is Alzheimer's disease. Alzheimer's disease is characterized by a progressive loss of brain cells and other irregularities of the brain.
The clock test is a non-verbal screening tool that may be used as part of the assessment for dementia, Alzheimer's, and other neurological problems. The clock test screens for cognitive impairment. The individual being screened is asked to draw a clock with the hour and minute hands pointing to a specific time.
Dementia affects about 5 million adults over 65 years old in the United States. A new test you can take at home may help detect early symptoms of the disease. The test, known as SAGE, can be taken online or downloaded and completed at your doctor's office.
For most people with Alzheimer's — those who have the late-onset variety — symptoms first appear in their mid-60s or later. When the disease develops before age 65, it's considered early-onset Alzheimer's, which can begin as early as a person's 30s, although this is rare.
How long will the assessment take? The clinical assessment usually takes up to 1½ hours. During the first appointment we will usually meet and answer your questions about the assessment. You will also be asked about the problems you are having and about your life in general.
How long will memory testing take? The testing will take about an hour and half (90 minutes). Being a little nervous or anxious is normal and expected. If you get tired, you can ask the person testing you for a break.
What happens during a memory test? During the examination the patient will not feel anything special. It is important that you sit in a comfortable and safe place. In conjunction with the memory test, the specialist is likely to perform a general physical examination and other reasoning skills will be evaluated.
Common early symptoms of dementia
memory loss. difficulty concentrating. finding it hard to carry out familiar daily tasks, such as getting confused over the correct change when shopping. struggling to follow a conversation or find the right word.
Detecting cognitive impairment is a required element of Medicare's Annual Wellness Visit (AWV).
Memory loss warning signs: When should you worry? Walking into a room and forgetting why you entered. Getting lost in familiar surroundings. Having trouble recalling the names of unfamiliar people.
What do the results mean? If your test results were not normal, it means you have some problem with memory or other mental function. But it won't diagnose the cause. Your health care provider may need to do more tests to find out the reason. Some types of cognitive impairment are caused by treatable medical conditions.
A score of 26 and higher is considered normal. In the initial study data, normal controls had an average score of 27.4. People with mild cognitive impairment (MCI) scored an average of 22.1. People with Alzheimer's disease had an average score of 16.2.
At a Glance. A new blood testing technique could help researchers detect Alzheimer's disease prior to onset or in those showing early signs of dementia. The approach could be less invasive and costly than current brain imaging and spinal fluid tests, enabling earlier treatments and testing of novel approaches.
