Physicians use diagnostic tools combined with medical history and other information, including neurological exams, cognitive and functional assessments, brain imaging (MRI, CT, PET) and cerebrospinal fluid or blood tests to make an accurate diagnosis.
Abstract. 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 five-minute cognitive test (FCT) was designed to capture deficits in five domains of cognitive abilities, including episodic memory, language fluency, time orientation, visuospatial function, and executive function.
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.
The SAGE test is a 12-question exam that measures cognitive functioning and may help a physician determine whether Alzheimer's is present. It's recommended that you bring your completed test to a medical professional who can score and interpret the results. If necessary, your doctors will provide further screening.
The GPCOG is a screening tool for cognitive impairment designed for use in primary care and is available in multiple languages. Mini-Cog - The Mini-Cog is a 3-minute test consisting of a recall test for memory and a scored clock-drawing test.
The Mini-Cog© is a fast and simple screening test to help detect dementia in its early stages. In just 3 minutes, Mini-Cog© can help doctors and other professional care providers identify possible cognitive impairment in older patients.
The Self-Administered Gerocognitive Exam (SAGE) is a brief self-administered cognitive screening instrument used to identify mild cognitive impairment (MCI) from any cause and early dementia.
The Four Word Short-Term Memory Test presents subjects with four words at the rate of one word per second and subjects are then asked to recall the words following a distractor interval of counting backwards by threes for 5, 15 or 30 s.
Neurological Evaluation
People may be asked to name objects, follow verbal and written commands, write a sentence, or draw a complex shape. Doctors may ask you to walk a short distance, because problems with gait can signal other conditions involving memory loss, such as normal pressure hydrocephalus.
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).
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.
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).
Short-term memory/delayed recall: Five words are read. The test-taker is asked to repeat them. After completing other tasks, the person is asked to repeat each of the five words again. If they can't recall them, they're given a cue of the category that the word belongs to.
A self-administered test can screen for memory loss
Individuals can take this test in the privacy of their own home and bring the results with them to the office. The results can then be used to determine whether additional work up and/or referral to a specialist is indicated.
A short term memory test is very self-explanatory. The user is shown multiple digits of numbers and asked to remember them. Then, the numbers are taken off the screen and the user is asked to type the numbers they remembered in.
Some of the more common triggers for dementia like a change in environment, having personal space invaded, or being emotionally overwhelmed may be easier to handle if you mentally practice your response before you react.
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.
Neuropsychological evaluation.
This process lasts around four hours and includes a series of in-depth analyses, such as one-on-one interviews and written and oral tests. These assessments are designed to gauge specific cognitive functions, like attention, problem solving, spatial skills, and executive functioning.
A typical neuropsychological evaluation for a patient with dementia will last 2 or 3 hours, depending on the patient's tolerance, and will involve standardized testing of memory, attention, processing speed, language, visual-spatial skills, executive functioning, and motor skills.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
