Dementia, now clinically termed Major Neurocognitive Disorder (MND) in DSM-V, describes 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 characterized by persistent cognitive decline and reduced ability to perform everyday tasks. Alzheimer’s disease stands as the most prevalent form of MND, accounting for approximately 70% of cases. This progressive disease unfolds through stages, from a preclinical phase with subtle brain changes to mild, moderate, and severe stages marked by increasing cognitive and functional impairments. Currently, there is no cure for Alzheimer’s, but ongoing research strives to develop treatments to manage symptoms, delay progression, and identify early biomarkers.
This article delves into the nursing process for patients experiencing MND, with a specific focus on Impaired Memory Nursing Diagnosis Care Plan. It will provide a comprehensive overview of nursing assessments, interventions, and care plans tailored to address memory impairment and related challenges in dementia care.
Nursing Process for Impaired Memory in Dementia
As MND advances, individuals often experience self-care deficits and increased safety risks. Memory loss, a hallmark symptom, significantly contributes to these challenges. Nurses play a vital role in addressing these complex needs, focusing on patient safety, emotional well-being, and supporting families navigating the complexities of dementia care. Understanding impaired memory as a core nursing diagnosis is fundamental to creating effective care plans.
Nursing Assessment for Impaired Memory
The initial step in addressing impaired memory is a thorough nursing assessment. This involves gathering subjective and objective data related to the patient’s cognitive function, memory, and overall health status.
Review of Health History
1. Obtain Medical History: Discuss pre-existing conditions with the patient and/or caregiver that may elevate the risk of neurocognitive disorders. These include:
2. Identify Nonmodifiable Risk Factors: Acknowledge nonmodifiable risk factors for Alzheimer’s disease/MND:
- Advancing age
- Family history of MND or Alzheimer’s disease
- Genetic predispositions
- Down syndrome
- Female gender
3. Family History of Dementia: Inquire about family history, as the risk increases with a first-degree relative diagnosed with MND.
4. Substance Abuse History: Review any history of heavy alcohol consumption and smoking, as these habits can negatively impact brain health and increase dementia risk.
5. Medication Review: Scrutinize the patient’s medication list, noting medications such as analgesics, antihistamines, CNS agents, muscle relaxers, and respiratory medications that might induce delirium and confusion, especially in older adults.
6. Baseline MND Symptoms: Discuss MND symptoms with the patient and caregiver to establish a baseline. Memory loss progression and its impact on daily life should be carefully documented. Differentiate between gradual cognitive decline and abrupt mental status changes due to other conditions.
7. Current Functional Status & Instrumental ADLs: Compassionately assess the patient’s current functional status, including instrumental Activities of Daily Living (IADLs).
- Inquire about assistance needed with ADLs (bathing, dressing, cooking, eating).
- Assess driving ability and safety.
- Evaluate home safety, including risks of wandering and emergency preparedness.
- Inquire about IADLs such as managing finances and appointments.
These insights are crucial for diagnosing MND and monitoring its progression, particularly concerning impaired memory.
8. Hospitalization Risk Factors: Recognize that hospitalization can exacerbate confusion in patients with MND due to unfamiliar environments, increasing risks of agitation, falls, and elopement.
9. Sleep Patterns and Routines: Review typical sleep patterns, as MND often disrupts the sleep-wake cycle, leading to fragmented sleep and sundowning, characterized by increased confusion and delusions in the evening. Poor sleep significantly worsens cognitive deficits, including impaired memory.
Physical Assessment
1. Observe Appearance, Gait, and Affect: Assess general appearance, hygiene, dress, and posture. Observe gait and balance, noting affect, responsiveness, and mood for clues about cognitive status and memory function.
2. Assess Orientation: Evaluate mental status through:
- Orientation to person, place, time, and situation.
- Speech clarity.
- Ability to follow directions.
- Attention span and concentration.
- Appropriateness of responses, all which are indicators of memory and cognitive function.
3. Standardized Cognitive Assessments: Utilize standardized assessments, often administered by physicians or advanced providers, to evaluate cognitive function formally. Nurses may assist or review results of tests like:
- Mini-Mental Status Examination (MMSE)
- The Saint Louis University Mental Status (SLUMS) exam
- The Montreal Cognitive Assessment (MoCA)
These tools are vital for quantifying the degree of impaired memory.
4. Observe Symptoms Affecting Cognition and Physical Function: Understand the progressive stages of MND and Alzheimer’s disease:
- Preclinical: Brain changes occur without noticeable symptoms.
- Mild: Memory loss becomes apparent, with forgetfulness of familiar places, difficulty with complex tasks, and subtle personality changes. This stage often marks initial diagnosis.
- Moderate: Memory loss and confusion intensify, impacting language, logical thinking, and learning. Behavioral changes like wandering, hallucinations, and paranoia may emerge.
- Severe: Extensive brain atrophy occurs. Patients lose recognition of familiar faces, cannot communicate meaningfully, and develop physical symptoms like swallowing difficulties and loss of bowel and bladder control.
Diagnostic Procedures
1. Blood Samples: Laboratory tests help rule out other conditions mimicking dementia:
- Complete blood count
- Urinalysis
- Metabolic panel
- Vitamin B12 and Folate levels
- Thyroid function tests
- Serological tests for syphilis and HIV
- In specific cases: Erythrocyte sedimentation rate, Lumbar puncture, Heavy metal screen, Ceruloplasmin levels, Lyme disease titer, Serum protein electrophoresis
2. Diagnostic Imaging: Brain imaging is crucial for initial evaluation, rapid cognitive decline, or atypical presentations:
- Brain MRI: Evaluates vascular disease, ischemic changes, and brain atrophy.
- Computerized Tomography (CT): Rules out acute neurological issues like stroke or brain masses but offers limited information for dementia diagnosis.

Nursing Interventions for Impaired Memory
Effective nursing interventions are crucial in managing impaired memory and supporting patients with dementia.
1. Medication Administration: Administer prescribed medications to manage cognitive function and secondary symptoms:
- NMDA antagonists (e.g., Namenda): Reduce glutamate action to improve cognitive function.
- Cholinesterase inhibitors (e.g., Galantamine, Rivastigmine, Donepezil): Slow symptom progression by preventing acetylcholine breakdown, aiding in memory and cognition.
- Anti-amyloid beta monoclonal antibodies (e.g., donanemab, lecanemab): Disease-modifying treatments for mild Alzheimer’s, targeting amyloid plaques.
- Medications for secondary symptoms: Antidepressants/mood stabilizers, neuroleptics, and anxiolytics to manage behavioral and psychological symptoms.
2. Lifestyle Modifications: Encourage lifestyle changes to optimize cognitive performance and potentially slow memory decline:
- Enhance sleep hygiene.
- Adopt an anti-inflammatory diet.
- Engage in regular physical activity.
- Address hearing and vision loss.
- Reduce stress.
- Limit alcohol intake.
- Maintain healthy cholesterol, blood pressure, and glucose levels.
3. Safe Environment: Create a safe, structured environment to minimize confusion and enhance focus.
- Reduce clutter and noise.
- Remove hazards.
- Implement monitoring for wandering or falls.
4. Cognitive Stimulation: Encourage mentally stimulating activities like puzzles and brain teasers to keep the mind active and potentially slow cognitive decline and memory loss.
5. Caregiver Involvement and Education: Engage caregivers by providing comprehensive information about MND progression and coping strategies. Educate on techniques like redirection and reassurance to manage disorientation and prevent agitation.
6. Patient and Family Support: Connect patients and families with support organizations and resources for financial aid, respite care, and community support.
Nursing Care Plans for Impaired Memory
