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).
Health care providers often use a brief test such as the Short Test of Mental Status, the Montreal Cognitive Assessment (MoCA) or the Mini-Mental State Examination (MMSE). More detailed testing may help determine the degree memory is impaired.
Researchers developed a blood test that could detect Alzheimer's disease-promoting compounds in the blood long before symptoms emerged. The findings may lead to early diagnostic tests for Alzheimer's and other neurodegenerative diseases.
Current blood diagnostic methods can accurately detect abnormalities in plasma amyloid beta and the phosphorylated form of tau, hitting two of the three necessary checkmarks to confidently diagnose Alzheimer's.
Cognitive testing
A doctor may use tests to check the person's cognitive or thinking functions, such as memory, problem solving, counting and language skills, concentration and more.
Forgetfulness can arise from stress, depression, lack of sleep or thyroid problems. Other causes include side effects from certain medicines, an unhealthy diet or not having enough fluids in your body (dehydration). Taking care of these underlying causes may help resolve your memory problems.

Chemical and metabolic testing of the blood can indicate some muscle disorders, protein or fat-related disorders that affect the brain and inborn errors of metabolism. Blood tests can monitor levels of therapeutic drugs used to treat epilepsy and other neurological disorders.
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 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 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 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.
Mini-Mental Status Examination (MMSE)
The MMSE is the most common test for the screening of dementia. It assesses skills such as reading, writing, orientation and short-term memory.
MRI uses a powerful magnetic field, radio frequency pulses, and a computer to produce detailed pictures of organs, soft tissues, bones, and virtually all other internal body structures. Doctors may order an MRI scan of the head to rule out other conditions that can cause memory loss, such as tumors or infections.
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.
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.
You have trouble following a conversation. You find it hard to make decisions, finish a task or follow instructions. You start to have trouble finding your way around places you know well. You begin to have poor judgment.
Blood and urine tests to look for infections, toxins, or protein disorders.
Common causes of sudden confusion
a stroke or TIA ('mini stroke') a low blood sugar level (hypoglycaemia) diabetic ketoacidosis, a serious complication of diabetes caused by a lack of insulin in the body. certain medications, including digoxin, diuretics, steroids, and opiates.
Normal age-related memory loss doesn't cause a significant disruption in your daily life. For example, you might occasionally forget a person's name, but recall it later in the day. You might misplace your glasses sometimes. Or maybe you need to make lists more often than in the past to remember appointments or tasks.
It can be caused by a number of factors, including a nutritional deficiency, sleep deprivation, depression, side effects of some medications, or dementia. If you are suffering from short-term memory loss, it is important to speak to your doctor in order to get an accurate diagnosis.
When to visit the doctor for memory loss. If you, a family member, or friend has problems remembering recent events or thinking clearly, talk with a doctor. He or she may suggest a thorough checkup to see what might be causing the symptoms.
