Neurocognitive disorder due to Lewy bodies is
Characterized with short-term memory loss, unpredictable cognitive shifts, and sleep disturbances. Thus talking about recent days would be ineffective. Memories of remote events (e.g., married life, working years, young adulthood) usually remains fairly intact.

Eating a balanced diet Eating dark colored fruits and vegetables Using soy products Folate, Vitamins B12, C, and E Exercise Crossword puzzles Learning new hobby Socialization
Dementia vs Delirium
For Delirium: Reorient the patient to reality; provide a safe environment Do not reorient for late stage dementia instead use validation therapy, do not argue with them
The nurse assesses a client with a diagnosis of early-stage Alzheimer's disease. Which assessment findings would the nurse expect for this client?
Forgetfulness Personality changes
Levodopa/Carbidopa
Given together to increase dopamine Used for Parkinson's Decreases tremors and muscle rigidity Levodopa is converted to dopamine in the CNS and carbidopa prevents the breakdown of levodopa Side effects: nausea, vomiting, drowsiness, dyskinesia, orthostatic hypotension, darkening of urine and sweat, possible psychosis High protein meals decreases effectiveness. immediate release (IR), controlled release (CR)
Stress is one of the leading causes of chronic inflammation.
It also has direct links to major age-related health issues, from dementia to Alzheimer's disease.
Cog. Impairment diagnostic tests
Laboratory tests (rule out medical problems) Neuropsychometric testing (memory exam etc.) Brain imaging techniques (MRS)
Which intervention(s) will the nurse include in a care plan for a client with Alzheimer disease?
Limit choices. Toilet every 2 hours. Encourage participation in self-care
NAMENDA or NMDA (N-methyl-aspartate) receptor antagonist
Memantine Alzheimer's Disease
Which characteristic mental change occurs with delirium and differentiates it from dementia?
Rapid-onset confusion
What are signs and symptoms of levodopa toxicity?
Symptoms of overdose may include: severe dizziness, irregular heartbeat, mental/mood changes (such as agitation).
Vascular dementia. This type of dementia is caused by damage to the vessels that supply blood to your brain.
The most common signs of vascular dementia include difficulties with problem-solving, slowed thinking, and loss of focus and organization. These tend to be more noticeable than memory loss.
CAUSES/RISK FACTORS OF Parkinsons disease
Unknown Genetic factors Environmental factors - Exposure to pesticides, Herbicides, and Industrial chemicals and metals Drinking well water Age (being older than 40 yrs old) Decreased estrogen levels
Lewy body dementia S&S
acting out one's dreams in sleep, seeing things that aren't there (visual hallucinations), and problems with focus and attention. Other signs include uncoordinated or slow movement, tremors, and rigidity (parkinsonism).
Dopamine agonists for PD Apomorphine, Pramipexole, Ropinirole, Rotigotine-(transdermal patch to maintain consistent level of dopamine)
adverse effects: orthostatic (postural) hypotension, hallucinations, sleepiness, and drowsiness.
CAM (Confusion Assessment Method)
is a standardized evidence-based tool that enables non-psychiatrically trained clinicians to identify and recognize delirium quickly and accurately in both clinical and research settings.
Mini Cog
is another screening tool that can be administered in 5 minutes or less and requires minimal training. 3 item recall, clock drawing test (CDT)
The mental changes associated with delirium have a rapid onset and are usually
precipitated by an infection or medication change
orthostatic hypotension (levodopa/carbidopa) (Parkinsons Pharmo)
temporary low BP and dizziness when suddenly rising from a sitting or reclining position
A client with moderate dementia asks the nurse to find her son who is deceased. What is the nurse's most appropriate response?

The nurse is caring for a community-dwelling older adult who is suffering from confusion. Which are the correct nursing interventions in this situation?
Provide a protective environment. Assist with personal hygiene. Promote activities that reinforce reality.
constipation treatment
fluids, high-fiber foods, and exercise should be recommended to help keep the stools soft
Parkinsonism
Having tremor, muscle rigidity, stooped posture, and a shuffling gait. (doesn't guarantee they have parkinsons disease)

However, it treats some of the symptoms of Alzheimer's disease, Parkinson's disease or dementia with Lewy bodies. -Reduces behavioral symptoms, particularly mood disturbances and delusions -Client should get regular liver function tests and report light stools and jaundice to the primary health care provider Take w meals to avoid side effects? Side effects: constipation, insomnia, nausea, vomiting
Alzheimer's disease. Most common cause of dementia. PATHO:
Alzheimer's disease patients have plaques and tangles in their brains. Plaques are clumps of a protein called beta-amyloid, and tangles are fibrous tangles made up of tau protein. It's thought that these clumps damage healthy neurons and the fibers connecting them. Neurotransmitter abnormalities. Age, Gender, Genetics
The nurse assists in the care of four older clients whose clinical features are shown in the accompanying chart. Which client may have dementia?
Client 1 has normal psychomotor behavior. The attention of the client is also indicated to be normal. Moreover, misperceptions are absent. Client 1 may likely have dementia. Hypokinetic psychomotor behavior, impaired attention, and difficulty in distinguishing between reality and perceptions may signify delirium. Hyperkinetic behavior and inattention with hallucinations may also signify delirium. Psychomotor retardation, easily distractible attention, and illusions may be caused by depression
Factors that Cause Delirium
Drug therapy (especially anticholinergics, opioids, and psychoactive drugs) Fluid and electrolyte imbalances Infections, especially urinary tract infection, pneumonia, and sepsis Fecal impaction or severe diarrhea Surgery (especially fracture hip repair and post transplant) Metabolic problems such as hypoglycemia Neurologic disorders such as tumors Circulatory, renal, and pulmonary disorders causing hypoxia Nutritional deficiencies Hypoxemia (decreased arterial oxygen level) Mechanical ventilation Insomnia Relocation Major loss

delirium
an acutely disturbed state of mind that occurs in fever, intoxication, and other disorders and is characterized by restlessness, illusions, and incoherence of thought and speech, confusion
Rivastigmine is a cholinesterase inhibitor
provides a modest short-term cognitive benefit for some people with mild to moderate Alzheimer dementia. It works by increasing acetylcholine at cholinergic synapses. It is NOT approved for people with SEVERE disease
executive function
the cognitive ability to organize and prioritize the many thoughts that arise from the various parts of the brain, allowing the person to anticipate, strategize, and plan behavior
