Alzheimer\u2019s disease is the most common cause, but vascular disease, Lewy body disease, frontotemporal degeneration, mixed dementia, and other conditions can also produce dementia symptoms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>seven stages of dementia<\/strong> usually refer to the Global Deterioration Scale developed by Dr. Barry Reisberg and colleagues. This framework describes a continuum from no noticeable cognitive impairment to very severe cognitive and physical decline. It is one of several staging systems, and symptoms, progression, and care needs can differ considerably from one person to another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Laboratory testing cannot determine a person\u2019s dementia stage by itself. Blood and urine tests may instead help identify thyroid disorders, vitamin deficiencies, anemia, infections, metabolic abnormalities, inflammation, and other conditions that may cause, resemble, or worsen cognitive symptoms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Through <a href=\"https:\/\/www.ultalabtests.com\/testing\/categories\/cognitive-health\"><strong>Ulta Lab Tests\u2019 Cognitive Health testing category<\/strong><\/a>, patients can explore relevant laboratory testing and use their results to support more informed conversations with qualified healthcare professionals.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Medical disclaimer:<\/strong> This article is for educational purposes only.

It involves a decline in one or more cognitive abilities, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Memory<\/li>\n\n\n\n<li>Language and communication<\/li>\n\n\n\n<li>Attention and concentration<\/li>\n\n\n\n<li>Judgment and problem-solving<\/li>\n\n\n\n<li>Visual and spatial processing<\/li>\n\n\n\n<li>Planning and organization<\/li>\n\n\n\n<li>Social behavior or personality<\/li>\n\n\n\n<li>The ability to complete everyday activities<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Memory loss alone does not necessarily mean that someone has dementia. Poor sleep, depression, medication effects, hearing loss, vision impairment, vitamin deficiencies, thyroid disease, infections, metabolic disturbances, alcohol use, and other medical conditions may affect thinking or memory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A dementia diagnosis generally requires evidence that cognitive decline is interfering with independent functioning. Healthcare professionals therefore consider not only cognitive test results but also whether a person can manage medications, finances, transportation, meals, appointments, hygiene, communication, and household responsibilities.<\/p>\n\n\n\n<h2 id=\"h-what-are-the-seven-stages-of-dementia\" class=\"wp-block-heading\">What Are the Seven Stages of Dementia?<\/h2>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Direct answer:<\/strong> The seven stages are no cognitive decline, very mild cognitive decline, mild cognitive decline, moderate cognitive decline, moderately severe cognitive decline, severe cognitive decline, and very severe cognitive decline.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">The Global Deterioration Scale was developed to describe cognitive and functional decline associated primarily with degenerative dementias such as Alzheimer\u2019s disease. Stages 1 through 3 are often considered pre-dementia stages, while stages 4 through 7 describe increasing levels of dementia and dependence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The model does not perfectly describe every form of dementia. Vascular dementia may progress in a stepwise pattern. Lewy body dementia can involve pronounced fluctuations, movement symptoms, visual hallucinations, or sleep disturbances. Frontotemporal dementia may initially affect behavior or language more than memory. Mixed dementia can combine features of several conditions.<\/p>\n\n\n\n<h2 id=\"h-the-seven-stages-of-dementia-at-a-glance\" class=\"wp-block-heading\">The Seven Stages of Dementia at a Glance<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-light-background-color has-background has-fixed-layout\"><thead><tr><th>Stage<\/th><th>General Description<\/th><th>Typical Cognitive or Functional Changes<\/th><th>Common Support Needs<\/th><\/tr><\/thead><tbody><tr><td><strong>Stage 1<\/strong><\/td><td>No cognitive decline<\/td><td>No noticeable memory, reasoning, or functional difficulties<\/td><td>Routine preventive healthcare and attention to new concerns<\/td><\/tr><tr><td><strong>Stage 2<\/strong><\/td><td>Very mild cognitive decline<\/td><td>Occasional word-finding difficulty, misplaced objects, or subjective forgetfulness<\/td><td>Monitoring and review of sleep, stress, hearing, medications, and general health<\/td><\/tr><tr><td><strong>Stage 3<\/strong><\/td><td>Mild cognitive decline<\/td><td>Noticeable difficulty with concentration, organization, learning names, work performance, or remembering information<\/td><td>Clinical evaluation, safety review, and assistance with complex tasks when needed<\/td><\/tr><tr><td><strong>Stage 4<\/strong><\/td><td>Moderate cognitive decline or mild dementia<\/td><td>Difficulty managing finances, planning meals, following current events, traveling independently, or completing complex tasks<\/td><td>Help with finances, medications, transportation, legal planning, and household organization<\/td><\/tr><tr><td><strong>Stage 5<\/strong><\/td><td>Moderately severe cognitive decline or moderate dementia<\/td><td>Confusion about time or location, major memory gaps, and difficulty choosing appropriate clothing<\/td><td>Regular assistance with daily routines and increased supervision<\/td><\/tr><tr><td><strong>Stage 6<\/strong><\/td><td>Severe cognitive decline<\/td><td>Extensive memory loss, sleep disruption, personality or behavioral changes, wandering, and difficulty with dressing or toileting<\/td><td>Close supervision, personal-care assistance, home-safety measures, and caregiver support<\/td><\/tr><tr><td><strong>Stage 7<\/strong><\/td><td>Very severe cognitive decline or late-stage dementia<\/td><td>Limited speech, loss of mobility, impaired swallowing, and inability to complete basic self-care<\/td><td>Continuous assistance, swallowing and nutrition assessment, comfort-focused care, and advanced-care planning<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">These descriptions are general guides, not a timetable. A person may have characteristics from more than one stage, remain stable for an extended period, or decline differently because of infection, hospitalization, stroke, medication effects, delirium, or another health condition.<\/p>\n\n\n\n<h2 id=\"h-stage-1-no-cognitive-decline\" class=\"wp-block-heading\">Stage 1: No Cognitive Decline<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At stage 1, no memory or thinking impairment is apparent to the person, family members, or healthcare professionals. The individual can generally work, drive, manage finances, communicate, and perform daily activities independently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stage 1 does not mean that everyone is experiencing the biological beginning of a brain disease. It simply means the clinical scale detects no cognitive impairment. Although biological changes associated with Alzheimer\u2019s disease can begin before symptoms, specialized biomarker testing is not intended as routine screening for every symptom-free adult.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Helpful actions include maintaining preventive healthcare, addressing hearing or vision impairment, managing cardiovascular and metabolic risk factors, and discussing significant family or medical concerns with a healthcare professional.<\/p>\n\n\n\n<h2 id=\"h-stage-2-very-mild-cognitive-decline\" class=\"wp-block-heading\">Stage 2: Very Mild Cognitive Decline<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Stage 2 may involve mild lapses such as forgetting a familiar word, losing keys, or having trouble recalling a name. These experiences may reflect normal aging, stress, fatigue, poor sleep, medication effects, or the earliest signs of a cognitive disorder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Symptoms at this stage generally do not interfere with work or independent living and may not be apparent during a brief clinical examination. Persistent or worsening changes, particularly those noticed by family members, should be discussed with a healthcare professional.<\/p>\n\n\n\n<h2 id=\"h-stage-3-mild-cognitive-decline\" class=\"wp-block-heading\">Stage 3: Mild Cognitive Decline<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At stage 3, cognitive changes become more noticeable. A person may have difficulty retaining information, finding words, organizing projects, navigating unfamiliar places, or performing as efficiently at work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This stage may correspond with <strong>mild cognitive impairment<\/strong>, or MCI. People with MCI have noticeable and sometimes measurable cognitive changes but remain independent in most daily activities. MCI has several possible causes, and not everyone with MCI develops dementia. Symptoms may remain stable, improve, or progress depending on the underlying cause.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A comprehensive evaluation during this stage may help identify medication effects, depression, sleep apnea, nutritional deficiencies, thyroid dysfunction, hearing loss, or other contributors. It can also establish a baseline for monitoring changes over time.<\/p>\n\n\n\n<h2 id=\"h-stage-4-moderate-cognitive-decline-or-mild-dementia\" class=\"wp-block-heading\">Stage 4: Moderate Cognitive Decline or Mild Dementia<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Stage 4 is commonly considered the point at which mild dementia becomes clinically evident. A person may have trouble managing bills, following complex instructions, planning meals, remembering recent events, or organizing travel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Basic self-care often remains intact, but complex daily activities become harder. The individual may withdraw from challenging conversations or situations because they recognize their difficulties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is an important stage for discussing transportation, medication management, financial safeguards, advance directives, home safety, caregiver responsibilities, and the possible need for evaluation by a neurologist, geriatrician, or memory specialist.<\/p>\n\n\n\n<h2 id=\"h-stage-5-moderately-severe-cognitive-decline\" class=\"wp-block-heading\">Stage 5: Moderately Severe Cognitive Decline<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Major gaps in memory and orientation become more apparent during stage 5. The person may forget an address, telephone number, date, season, or current location. Assistance may be needed to select suitable clothing or maintain a daily schedule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many people still recognize close family members and retain important information about themselves. Eating and toileting may remain largely independent, although supervision and structured routines become increasingly important.<\/p>\n\n\n\n<h2 id=\"h-stage-6-severe-cognitive-decline\" class=\"wp-block-heading\">Stage 6: Severe Cognitive Decline<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Stage 6 often brings extensive memory impairment and increasing dependence. The person may need help dressing, bathing, toileting, eating, and completing other personal-care activities. Sleep-wake patterns may become disrupted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Behavioral or psychological changes may include anxiety, suspiciousness, agitation, hallucinations, repetitive actions, or wandering. A sudden or dramatic behavioral change should be medically evaluated rather than assumed to be routine dementia progression. Pain, dehydration, constipation, infection, medication effects, and other illnesses can cause abrupt worsening.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Caregiver support, wandering precautions, fall prevention, medication supervision, home-safety planning, and respite care become especially important.<\/p>\n\n\n\n<h2 id=\"h-stage-7-very-severe-cognitive-decline\" class=\"wp-block-heading\">Stage 7: Very Severe Cognitive Decline<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">During stage 7, speech, movement, swallowing, and awareness of the environment may become profoundly impaired. The person usually requires assistance with eating, hygiene, transfers, toileting, mobility, and nearly all daily activities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Care planning may involve swallowing and nutrition evaluation, pressure-injury prevention, mobility support, comfort measures, caregiver assistance, and discussions about goals of care. Families may benefit from palliative-care or hospice consultation when clinically appropriate.<\/p>\n\n\n\n<h2 id=\"h-why-the-seven-stages-of-dementia-matter\" class=\"wp-block-heading\">Why the Seven Stages of Dementia Matter<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding dementia stages may help families anticipate changes, but a stage should never replace an individualized assessment. Staging can help guide conversations about:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The level of assistance currently needed<\/li>\n\n\n\n<li>Medication and financial management<\/li>\n\n\n\n<li>Driving and transportation safety<\/li>\n\n\n\n<li>Fall and wandering risk<\/li>\n\n\n\n<li>Home modifications<\/li>\n\n\n\n<li>Caregiver workload<\/li>\n\n\n\n<li>Legal and financial planning<\/li>\n\n\n\n<li>Future living arrangements<\/li>\n\n\n\n<li>Advance-care preferences<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The most meaningful question is often not simply, \u201cWhat stage is this?\u201d but, \u201cWhich abilities remain, which activities are becoming unsafe, and what support would preserve dignity and independence?\u201d<\/p>\n\n\n\n<h2 id=\"h-symptoms-risk-factors-and-laboratory-tests\" class=\"wp-block-heading\">Symptoms, Risk Factors, and Laboratory Tests<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Laboratory tests do not prove that a symptom is caused by dementia. They may help identify another medical issue that deserves attention or may be contributing to cognitive symptoms.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table

The FDA has cleared blood assays intended to aid qualified healthcare professionals in evaluating Alzheimer\u2019s-related amyloid pathology in certain adults with cognitive symptoms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These specialized tests may measure biomarkers such as phosphorylated tau or relationships between tau and beta-amyloid. They are different from routine tests used to investigate nutritional, thyroid, metabolic, inflammatory, or infectious contributors to cognitive symptoms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Alzheimer\u2019s blood biomarkers are not intended to function as stand-alone dementia diagnoses or universal screening tests for symptom-free adults. Results must be interpreted with clinical history, objective cognitive assessment, neurological evaluation, and other relevant information. Some tests are intended primarily for specialty-care settings, while others may help clinicians determine whether additional Alzheimer\u2019s evaluation is appropriate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because product indications, availability, clinical guidance, and regulatory notices can change, the exact test and its current intended use should be verified before publication, ordering, or clinical interpretation.<\/p>\n\n\n\n<h2 id=\"h-recommended-testing-approach\" class=\"wp-block-heading\">Recommended Testing Approach<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Testing should be individualized.

What are the seven stages of dementia?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The seven stages are no cognitive decline, very mild cognitive decline, mild cognitive decline, moderate cognitive decline, moderately severe cognitive decline, severe cognitive decline, and very severe cognitive decline. The stages describe general changes in cognition, independence, behavior, and physical function, but people do not always progress through them uniformly.<\/p>\n\n\n\n<h3 id=\"h-2-at-what-stage-does-dementia-usually-begin\" class=\"wp-block-heading\">2. At what stage does dementia usually begin?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Within the seven-stage framework, stages 1 through 3 are generally considered pre-dementia stages. Stage 3 may correspond to mild cognitive impairment. Dementia generally becomes clinically apparent around stage 4, when cognitive decline begins interfering with complex independent activities such as managing finances, planning meals, organizing travel, or following detailed instructions.<\/p>\n\n\n\n<h3 id=\"h-3-is-mild-cognitive-impairment-the-same-as-dementia\" class=\"wp-block-heading\">3. Is mild cognitive impairment the same as dementia?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. Mild cognitive impairment causes noticeable and sometimes measurable changes in memory or other thinking abilities, but the person generally remains independent in most daily activities. Dementia involves cognitive decline severe enough to interfere with daily functioning. Some people with mild cognitive impairment progress to dementia, while others remain stable or improve.<\/p>\n\n\n\n<h3 id=\"h-4-can-a-blood-test-diagnose-dementia\" class=\"wp-block-heading\">4. Can a blood test diagnose dementia?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Routine blood tests cannot independently diagnose or stage dementia. They may identify anemia, thyroid dysfunction, vitamin deficiencies, metabolic abnormalities, inflammation, or infections that can affect cognition. Selected Alzheimer\u2019s blood biomarkers may help qualified clinicians evaluate Alzheimer\u2019s-related pathology in appropriate symptomatic patients, but they are not stand-alone diagnoses or universal screening tests.<\/p>\n\n\n\n<h3 id=\"h-5-what-blood-tests-may-be-considered-for-memory-loss\" class=\"wp-block-heading\">5. What blood tests may be considered for memory loss?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A baseline evaluation may include a <a href=\"https:\/\/www.ultalabtests.com\/test\/complete-blood-count-with-differential-and-platelets-cbc-test\">Complete Blood Count with Differential and Platelets<\/a>, <a href=\"https:\/\/www.ultalabtests.com\/test\/comprehensive-metabolic-panel-cmp\">Comprehensive Metabolic Panel<\/a>, <a href=\"https:\/\/www.ultalabtests.com\/test\/tsh\">TSH Test<\/a>, <a href=\"https:\/\/www.ultalabtests.com\/test\/vitamin-b12-test\">Vitamin B12 Test<\/a>, <a href=\"https:\/\/www.ultalabtests.com\/test\/homocysteine-test\">Homocysteine Test<\/a>, <a href=\"https:\/\/www.ultalabtests.com\/test\/c-reactive-protein-test\">C-Reactive Protein Test<\/a>, and <a href=\"https:\/\/www.ultalabtests.com\/test\/sed-rate-test\">Sed Rate Test<\/a>. Other tests may be added according to symptoms and risk factors.<\/p>\n\n\n\n<h3 id=\"h-6-can-vitamin-b12-deficiency-resemble-dementia\" class=\"wp-block-heading\">6. Can vitamin B12 deficiency resemble dementia?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Vitamin B12 deficiency can cause memory changes, slowed thinking, fatigue, anemia, numbness, balance problems, or other neurological symptoms. A <a href=\"https:\/\/www.ultalabtests.com\/test\/vitamin-b12-test\">Vitamin B12 Test<\/a> can help evaluate deficiency, although a borderline result may require a <a href=\"https:\/\/www.ultalabtests.com\/test\/methylmalonic-acid-test\">Methylmalonic Acid Test<\/a>. Correcting a deficiency does not necessarily reverse cognitive decline caused by an unrelated neurological disease.<\/p>\n\n\n\n<h3 id=\"h-7-can-thyroid-problems-cause-memory-issues\" class=\"wp-block-heading\">7. Can thyroid problems cause memory issues?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Both underactive and overactive thyroid conditions can affect energy, mood, concentration, sleep, and thinking. A <a href=\"https:\/\/www.ultalabtests.com\/test\/tsh\">TSH Test<\/a> is commonly used as an initial thyroid test. A <a href=\"https:\/\/www.ultalabtests.com\/test\/tsh-and-free-t4-test\">TSH and Free T4 Test<\/a> or other thyroid testing may be appropriate for clarification. An abnormal result does not prove that thyroid disease is the only cause of cognitive symptoms.<\/p>\n\n\n\n<h3 id=\"h-8-how-long-does-each-dementia-stage-last\" class=\"wp-block-heading\">8. How long does each dementia stage last?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There is no fixed duration for any stage. Progression depends on the underlying condition, age, general health, vascular disease, infections, medication effects, and many other factors. A person may remain stable for an extended period or decline more quickly following illness or hospitalization. Stage descriptions guide planning but cannot predict an exact timeline.<\/p>\n\n\n\n<h3 id=\"h-9-can-i-order-cognitive-health-laboratory-tests-without-a-doctor\" class=\"wp-block-heading\">9. Can I order cognitive-health laboratory tests without a doctor?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ulta Lab Tests allows patients to order many routine laboratory tests directly online where available. However, testing for memory loss should complement, not replace, a professional medical evaluation. Some specialized Alzheimer\u2019s biomarkers require clinician or specialist involvement. Sudden confusion, neurological deficits, or rapid decline require urgent medical care rather than routine direct-access testing.<\/p>\n\n\n\n<h3 id=\"h-10-when-is-confusion-an-emergency\" class=\"wp-block-heading\">10. When is confusion an emergency?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Confusion that begins suddenly over hours or days is not typical gradual dementia progression. Emergency evaluation is especially important when confusion occurs with weakness, facial drooping, speech problems, severe headache, fever, fainting, seizure, breathing difficulty, or loss of consciousness. Possible causes include stroke, infection, delirium, severe glucose abnormalities, electrolyte disturbances, or medication toxicity.<\/p>\n\n\n\n<h3 id=\"h-11-should-dementia-related-laboratory-tests-be-repeated\" class=\"wp-block-heading\">11. Should dementia-related laboratory tests be repeated?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Repeat testing depends on the initial result, symptoms, medical history, treatment, and the healthcare professional\u2019s follow-up plan. Vitamin deficiencies, thyroid abnormalities, anemia, diabetes, kidney function, and liver function may require monitoring. Frequently repeating normal tests without a clinical reason is unlikely to show whether dementia has progressed because staging primarily depends on cognitive and functional changes.<\/p>\n\n\n\n<h3 id=\"h-12-what-should-i-bring-to-a-dementia-evaluation\" class=\"wp-block-heading\">12. What should I bring to a dementia evaluation?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Bring a current medication and supplement list, previous laboratory and imaging results, a timeline of symptoms, relevant medical history, and examples of changes in daily functioning. A trusted family member or care partner can provide useful observations about finances, medications, driving, appointments, cooking, communication, falls, sleep, behavior, or personal care.<\/p>\n\n\n\n<h2 id=\"h-conclusion\" class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>seven stages of dementia<\/strong> provide a useful framework for describing the progression from normal cognition through mild cognitive impairment, increasing loss of independence, and very severe cognitive and physical decline. The stages are general guides and cannot fully capture every person\u2019s experience or every type of dementia.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Laboratory testing cannot determine a dementia stage, but it may help identify vitamin deficiencies, thyroid dysfunction, anemia, metabolic abnormalities, inflammation, vascular risk factors, infections, and other conditions that may contribute to cognitive symptoms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Through <a href=\"https:\/\/www.ultalabtests.com\/testing\/categories\/cognitive-health\"><strong>Ulta Lab Tests\u2019 Cognitive Health testing options<\/strong><\/a>, patients can access relevant laboratory testing with transparent pricing and secure online results. Laboratory findings and persistent changes in memory, thinking, behavior, judgment, or daily functioning should be reviewed with a qualified healthcare professional as part of a complete cognitive evaluation.<\/p>\n\n\n\n<h2 id=\"h-references\" class=\"wp-block-heading\">References<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Reisberg B, Ferris SH, de Leon MJ, Crook T. <em>The Global Deterioration Scale for Assessment of Primary Degenerative Dementia.<\/em> American Journal of Psychiatry. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/7114305\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/pubmed.ncbi.nlm.nih.gov\/7114305\/<\/a><\/li>\n\n\n\n<li>Alzheimer\u2019s Association. <em>Stages of Alzheimer\u2019s Disease.<\/em> <a href=\"https:\/\/www.alz.org\/alzheimers-dementia\/stages\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.alz.org\/alzheimers-dementia\/stages<\/a><\/li>\n\n\n\n<li>Alzheimer\u2019s Association. <em>What Is Dementia?<\/em> <a href=\"https:\/\/www.alz.org\/alzheimers-dementia\/what-is-dementia\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.alz.org\/alzheimers-dementia\/what-is-dementia<\/a><\/li>\n\n\n\n<li>National Institute on Aging. <em>What Is Dementia?
