Dementia, now clinically termed Major Neurocognitive Disorder (MND), represents a significant decline in cognitive function that disrupts daily living. It’s crucial to understand that MND is not a normal part of aging but a progressive condition requiring specialized care. Alzheimer’s disease stands as the most prevalent form of MND, accounting for approximately 70% of cases. This progressive disease unfolds through preclinical, mild, moderate, and severe stages over years, currently lacking a cure but with ongoing research focused on symptom management, delaying onset, and identifying biomarkers.
As MND progresses, individuals often experience increasing self-care deficits, impacting bathing, grooming, toileting, and feeding. Alzheimer’s disease, in particular, can lead to swallowing difficulties and heightened risks of aspiration pneumonia. Falls become a significant concern due to impaired reasoning and judgment, with patients attempting unassisted mobility despite physical limitations. Studies highlight the severity, indicating a high mortality rate within six months post-hospital discharge for dementia patients admitted for conditions like pneumonia or hip fractures.
Nurses play a vital role in treating the physical health challenges of patients complicated by neurocognitive disorders. A deep understanding of patient safety, emotional, and mental health is essential for providing optimal care to both patients and their families. This article delves into the nursing process, assessment, interventions, and care plans pertinent to dementia, aiming to equip healthcare professionals with the knowledge and tools necessary for effective dementia care.
Nursing Process in Dementia Care
The nursing process forms the cornerstone of patient care, especially in managing complex conditions like dementia. It begins with a comprehensive nursing assessment, followed by the identification of relevant nursing diagnoses. Based on these diagnoses, nurses develop and implement tailored care plans, evaluate their effectiveness, and adjust strategies as needed. This cyclical process ensures patient-centered care that addresses the evolving needs of individuals with dementia.
Nursing Assessment: Gathering Crucial Data
The initial step in providing effective nursing care for patients with dementia is a thorough nursing assessment. This involves collecting subjective and objective data across physical, psychosocial, emotional, and diagnostic domains. This section outlines key aspects of the nursing assessment process for dementia and Alzheimer’s disease.
Review of Health History: Uncovering Risk Factors and Baselines
1. Detailed Medical History Review: Collaborate with the patient and/or caregiver to thoroughly review the patient’s medical history. Identify pre-existing conditions that elevate the risk of neurocognitive disorders, such as:
- Cardiovascular disease
- Stroke
- Diabetes mellitus
- Hypertension
- Hyperlipidemia
- Traumatic brain injury
- Parkinson’s disease
- Multiple sclerosis
2. Nonmodifiable Risk Factor Assessment: Acknowledge and consider nonmodifiable risk factors that contribute to Alzheimer’s disease and MND:
- Advancing Age: The risk of dementia significantly increases with age.
- Family History: A family history of MND or Alzheimer’s disease elevates individual risk.
- Genetic Predisposition: Specific genetic mutations are linked to increased risk.
- Down Syndrome: Individuals with Down syndrome have a higher incidence of Alzheimer’s disease.
- Female Gender: Women are statistically more likely to be diagnosed with Alzheimer’s disease.
3. Family History of Dementia: Inquire about family history, particularly focusing on first-degree relatives with MND. A positive family history is a significant risk indicator.
4. Substance Abuse History: Discuss substance abuse history with the patient and caregivers. Heavy alcohol consumption and smoking are known to negatively impact brain health. Alcohol use disorders are associated with an increased risk of dementia, especially early-onset dementia, while smoking elevates the risk of vascular disease and dementia.
5. Medication Review: Scrutinize the patient’s medication list in detail. Be aware that certain medications, including some analgesics, antihistamines, CNS agents, muscle relaxers, and respiratory medications, can induce delirium and confusion in older adults (over 65 years) as a side effect.
6. Baseline Symptom Development: Discuss MND symptoms with the patient and caregiver to establish a baseline. Patients may have varying levels of awareness regarding their cognitive changes. Given the progressive nature of symptoms, documenting a timeline is crucial. Differentiate MND symptoms from conditions causing abrupt mental status changes.
7. Functional Status and Instrumental ADLs: Compassionately inquire about the patient’s current functional status and self-care routine at home. Assess both Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs):
- ADLs: Bathing, dressing, cooking, eating, toileting, mobility.
- IADLs: Driving, managing finances, making appointments, medication management, shopping, using technology.
Gather information on assistance needed with ADLs and IADLs. Assess home safety, including fire safety, wandering risks, and overall independence at home. These details are crucial for diagnosis and monitoring MND progression.
8. Hospitalization Risk Factors: Determine health and safety risk factors specific to hospitalization. Hospitalization can exacerbate confusion in MND patients due to the unfamiliar environment, increasing risks of agitation, falls, and elopement.
9. Sleep Pattern and Routine Review: Review typical sleep patterns and routines with the patient and caregiver. MND often disrupts the sleep-wake cycle, leading to fragmented and disrupted sleep. Poor sleep can worsen neurological deficits, including confusion, irritability, and reduced alertness. Also, assess for sundowning, a common phenomenon in dementia, characterized by increased confusion, agitation, and paranoid delusions in the evening hours.
Physical Assessment: Observing Cognitive and Physical Function
1. Appearance, Gait, and Affect Assessment: Observe the patient’s overall appearance, personal hygiene, dress, and posture. Assess gait, balance, affect, responsiveness, and mood during interactions for clues about cognitive status.
2. Orientation and Mental Status Evaluation: Evaluate the patient’s level of orientation through:
- Orientation to person, place, time, and situation.
- Speech clarity and coherence.
- Ability to follow simple and multi-step directions.
- Attention span and concentration.
- Appropriateness of responses and behavior.
3. Standardized Cognitive Assessments: Utilize standardized neuropsychological tests, typically administered by physicians or advanced practice providers. Nurses often assist with or review test results, such as:
- Mini-Mental State Examination (MMSE): A widely used brief cognitive assessment.
- Saint Louis University Mental Status (SLUMS) exam: Another cognitive screening tool, slightly more sensitive than MMSE.
- Montreal Cognitive Assessment (MoCA): Highly sensitive for detecting mild cognitive impairment and early Alzheimer’s.
4. Symptom Observation Across Dementia Stages: Understand and observe symptoms associated with different stages of Alzheimer’s disease:
- Preclinical Stage: Brain changes occur years before symptoms. Neurological testing is typically normal.
- Mild Stage: Noticeable memory loss, confusion about familiar places, difficulty with complex tasks (money management), reduced spontaneity, personality changes, and increased anxiety. Diagnosis often occurs at this stage.

- Severe Stage: Extensive brain atrophy, widespread plaques and tangles. Inability to recognize familiar faces or communicate meaningfully. Physical symptoms emerge: weight loss, swallowing difficulties, increased sleeping, incontinence. Patients often become bedridden, with death frequently resulting from secondary causes like aspiration pneumonia.
Diagnostic Procedures: Ruling Out Other Conditions
1. Blood Samples and Laboratory Tests: Laboratory tests are crucial for excluding other conditions that might mimic or exacerbate cognitive impairment:
- Complete Blood Count (CBC)
- Urinalysis
- Metabolic Panel (Electrolytes, Liver and Kidney Function)
- Vitamin B12 and Folate Levels (Deficiencies can cause cognitive issues)
- Thyroid Function Tests (Hypothyroidism can mimic dementia)
- Serological Tests for Syphilis and HIV (Rare causes of dementia)
In specific cases, providers may order additional tests:
- Erythrocyte Sedimentation Rate (ESR) and C-reactive protein (CRP) (Inflammatory markers)
- Lumbar Puncture (Cerebrospinal fluid analysis for protein markers indicative of Alzheimer’s)
- Heavy Metal Screen (Rule out heavy metal toxicity)
- Ceruloplasmin Levels (Wilson’s disease screening)
- Lyme Disease Titer (Neurological Lyme disease)
- Serum Protein Electrophoresis (Paraneoplastic syndromes)
2. Diagnostic Imaging: Brain imaging is often essential, particularly for initial evaluation, early-onset dementia, atypical presentations, or rapid cognitive decline.
- Brain Magnetic Resonance Imaging (MRI): Superior for evaluating vascular and ischemic disease, localized brain atrophy, and global atrophy associated with dementia.
- Computerized Tomography (CT): Primarily used to rule out acute neurological issues like stroke or brain tumors causing sudden symptom onset. CT is less helpful for diagnosing dementia itself.
Nursing Interventions: Enhancing Cognition and Safety
Nursing interventions are crucial in managing dementia, focusing on both cognitive enhancement and ensuring patient safety.
1. Medication Administration: Administer prescribed medications aimed at enhancing cognitive function and managing secondary symptoms:
-
Cognitive Enhancers:
- N-methyl-D-aspartate (NMDA) antagonist (Memantine/Namenda): Reduces glutamate action, protecting brain cells from excitotoxicity.
- Cholinesterase inhibitors (Donepezil, Rivastigmine, Galantamine): Slow symptom progression by preventing acetylcholine breakdown, improving neurotransmission.
- Anti-amyloid beta monoclonal antibodies (Donanemab, Lecanemab): Disease-modifying treatments for mild stage Alzheimer’s, targeting amyloid plaques in the brain.
-
Symptom Management Medications:
- Antidepressants or mood stabilizers: Manage irritability, depression, and rage.
