1) Alzheimer's disease is a progressive brain disease that destroys memory and cognitive function. Symptoms usually appear after age 60.
2) Pathophysiology involves changes in brain proteins like amyloid plaques and neurofibrillary tangles that lead to loss of neurons. The cause is unknown.
3) Treatment focuses on managing cognitive, behavioral and functional symptoms through cholinesterase inhibitors, memantine, behavioral therapies and safety measures. Lifestyle factors may help reduce risk but it is not preventable.
Alzheimer's disease is a progressive, degenerative disorder that attacks the brain's nerve cells, resulting in loss of memory, imagination and speaking skills, and behavioural changes. Alzheimer's disease is the most common cause of dementia, or loss of intellectual function, among people aged 65 and older.

Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

3. Alzheimer’s disease is an irreversible, progressive brain
disease that slowly destroys memory and disorders
cognitive function
4.
5.
6.
7. Although the risk of developing AD increases with age – in
most people with AD, symptoms first appear after age 60
(5% incidence) AD is not a part of normal aging.
11. Microscopically:
– Changes in the proteins of the nerve cells of the
cerebral cortex
– accumulation of neurofibrillary tangles and
neuritic plaques (deposits of protein and altered
cell structures on the interneuronal junctions)
granulovascular degeneration
– loss of cholinergic nerve cells (important in
memory, function, cognition
21. Diagnosis
• Medical history, history from relatives, and
behavioural observations.
• Neurological Examination and MSE
• CT, MRI, SPECT, PET can be used to help
exclude other cerebral pathology
22. Lab diagnosis
• complete blood count, sedimentation rate,
chemistry panel, thyroid-stimulating
hormone, test for syphilis, urinalysis, serum
B12, folate level, and test for HIV
• to rule out infectious or metabolic disorders
23. • cerebrospinal fluid (CSF) - tau protein and
beta-amyloid
Genetic testing
In families with a history of Alzheimer's
disease, test to confirm AD or to provide
information to at-risk family members regarding
their likelihood for development of AD
24. How is Alzheimer’s Disease managed at present?
• Ideally, management should involve an interdisciplinary
approach for assessment, treatment & education
• The roles of nutritionists, caregivers, nurses, social workers
and patients associations can be vital for the long term care
• Pharmacological treatment
– Cholinesterase inhibitors
– Memantine
25. The 3 targets for Pharmacotherapy
• Cognitive decline: memory, language,
orientation, concentration, etc.
• Behavioral abnormalities: delusions,
aggressiveness, anxiety, depression, psychosis
etc..
• Activities of Daily Living: dressing, bathing,
feeding, use of household appliances, etc
27. Nicotine is a cholinergic agonist that acts both
postsynaptically and pre-synaptically to release
acetylcholine
Melatonin - This neurohormone prevents
neuronal death caused by exposure to the
amyloid beta protein
28. Donepezil (Aricept)
• Widely used in mild to moderate cases
because it can be given once daily and is well
tolerated
• Starting at 5 mg hs and increased to 10 mg
after 4 to 6 weeks
29. Galantamine
• Given with food in dosage of 4 to 12 mg bid
Should be restarted at 4 mg bid if interrupted
for several days
• Dose should be reduced in cases of renal or
hepatic impairment
31. Memantine
• NMDA-receptor antagonist
• The first of a new class approved for moderate
to severe Alzheimer's
• Dosage is 10 mg bid
• Can be used with a cholinesterase inhibitor
32. • Patients with depressive symptoms should be
considered for antidepressant therapy
• Behavioral disturbances may require
pharmacologic treatment anxiolytics,
antipsychotics, anticonvulsants
33. Nonpharmacologic treatments used to improve
cognition:
• Environmental manipulation that decreases
stimulation
• Aromatherapy, Massage, Music therapy,
Exercise
34. Drug Alert
• Cholinesterase inhibitors initially aimed at improving memory and
cognition seem to have an important impact on the behavioral
changes that occur in patients with cognitive impairment
• improves the apathy, disinhibition, pacing, and hallucinations
commonly noted in dementia
• Be alert for drug interactions with NSAIDs, succinylcholine-type
muscle relaxants, cholinergic and anticholinergic agents, drugs that
slow the heart, and other drugs
35. Nursing assessment
• Perform cognitive assessment
• Orientation, insight, abstract thinking, concentration,
memory, verbal ability
• Assess for changes in behavior and ability to perform adls
• Evaluate nutrition and hydration
• Check weight, skin turgor, meal habits
• Assess motor ability, strength, muscle tone, flexibility
36. Nursing diagnoses
• Self-care deficit
• Constipation
• Disabled family coping
• Disturbed thought
• Imbalanced nutrition: Less than body
requirements Impaired verbal communication
37. • Ineffective coping
• Interrupted family processes
• Risk for infection
• Risk for injury
38. Interventions
• Establish an effective communication system
with the patient and his family to help them
adjust to the patient's altered cognitive
abilities
• Provide emotional support to the patient and
his family
• Encourage them to talk about their concerns
• Listen carefully to them
39. • Use a soft tone and a slow, calm manner when
speaking to him Because the patient may
misperceive his environment
• Allow the patient sufficient time to answer
your questions his thought processes are slow,
impairing his ability to communicate verbally
40. Intervention
• Administer ordered medications to the patient
and note their effects
• If the patient has trouble swallowing, check with
a pharmacist to see if tablets can be crushed or
capsules can be opened and mixed with a semi-
soft food
• Protect the patient from injury
• Provide a safe, structured environment
• Provide rest periods between activities because
these patients tire easily
41. • Encourage the patient to exercise to help
maintain mobility
• Encourage patient independence allow ample
time for the patient to perform tasks
• Encourage sufficient fluid intake and adequate
nutrition Provide assistance with menu selection
allow the patient to feed himself as much as he
can
• Provide a well-balanced diet with adequate fiber
• Avoid stimulants, such as coffee, tea, cola, and
chocolate
42. • Give the patient semisolid foods if he has dysphagia
• Insert and care for a nasogastric tube or a gastrostomy
tube for feeding as ordered
• Because the patient may be disoriented or
neuromuscular functioning may be impaired, take the
patient to the bathroom at least every 2 hours
• Assist the patient with hygiene and dressing as
necessary
• Many patients with Alzheimer's disease are incapable
of performing these tasks
44. Prevention
It is not a preventable condition.
Lifestyle risk factors for Alzheimer's can be
modified.
Changes in diet, exercise and habits — steps to
reduce the risk of cardiovascular disease — may
also lower your risk of developing Alzheimer's
disease
45. Heart-healthy lifestyle choices that may reduce
the risk of Alzheimer's include the following:
• Exercise regularly
• Eat a diet of fresh produce, healthy oils and
foods low in saturated fat
• Follow treatment guidelines to manage high
blood pressure, diabetes and high cholesterol
• Quit smoking
