Aging
Aging is the progressive, universal decline first in
functional reserve and then in function that occurs in
organisms over time.
Aging is heterogeneous.
Aging is not a disease; however, the risk of developing
disease is increased.
Geriatric Syndromes
Geriatric syndrome refers to a symptom presentation
that is common in older adults.
Most are multifactorial in origin.

Dementia and Delirium
Fall
Urinary Incontinence
Pressure Ulcers- due to immobility
Dementia and Delirium
Dementia is a syndrome of progressive decline in which
multiple intellectual abilities deteriorate, causing both
cognitive and functional impairment.
Dementia is a state of chronic confusion.
Delirium is an acute state of confusion. It is important to
differentiate delirium from dementia.
Dementia and Delirium cont…
Both dementia and delirium are characterized by :
Disorientation,
Memory impairment,
Paranoia,
Hallucinations,
Emotional lability,
Sleep-wake cycle reversal.
Dementia and Delirium cont…
Key features of delirium are:
acute onset
impaired attention
altered level of consciousness.
care of a patient with dementia
The main goals of care of a patient with dementia to
improve cognitive and physical functioning.
key goal is to identify and treat reversible causes of
cognitive impairment such as :
Infections
Electrolyte abnormalities
Vitamin deficiencies
Thyroid disease
Substance abuse
Medication
Psychiatric illnesses.
Falls
Excludes falls occurring from seizure, stroke, syncope.
Fall rates and risk of injury from falls increase with
age.
Annually ~30% of community dwelling adults >65
years fall.
While 50% of individuals >80 years fall.
Falls cont…
Most falls are multifactorial
Falling is sometimes a symptom of another disease,
such as:
Infections
Neurologic disorder
Medication side effect
Age-related physiologic changes
age-related physiologic changes
Decreased proprioception,
Increased postural sway,
Declines in baroreflex sensitivity resulting in
orthostatic hypotension.
RISK FACTORS FOR FALLS
Muscle weakness
History of falls
Gait or balance abnormality
Use of a walking aid
Visual impairment
Arthritis
Impaired activities of daily living
RISK FACTORS FOR FALLS
cont…
Depression
Cognitive impairment
Age over 80 years
Drugs:
Polypharmacy (four or more drugs)
Digoxin
Diuretics
Benzodiazepines ,phenothiazines,antidepressants
Type I anti-arrhythmics
History of fall
The evaluation of a fall should begin with a history :
Circumstances at the time of the fall,
Associated symptoms,
Thorough medication review of both prescription and
over-the-counter medications.
physical examination of fall
The physical examination should include
postural vital signs,
vision evaluation,
gait and balance testing,
musculoskeletal evaluation of joint stability and range of
motion.
environmental assessment of fall
An environmental assessment of the patient's home
that can increase fall risk, such as:
Loose carpets
Poor lighting
Urinary Incontinence
UI is a major problem for older adults
Up to age 80 years, UI affects women twice as
commonly as men
After age 80, both sexes are equally affected.
Urinary Incontinence
Leaking of urine or urinary Incontinence occurs in
four ways.
Stress incontinence,
Urge incontinence,
Mixed stress and urge incontinence,
Overflow incontinence.
incontinence evaluation
Measurement of postvoid residual (PVR) should be part of an
incontinence evaluation in all patients.
Under sterile conditions, the patient's bladder is catheterized 5–
10 min after the patient has voided. Generally, a PVR > 200 mL
suggests detrusor underactivity or obstruction.
The patient should be referred for further urologic evaluation.
Stress Incontinence
Stress incontinence - urethral sphincter mechanisms
are inadequate to hold urine during bladder filling,
rare in men.
leaking small amounts of urine during activities that
increase intraabdominal pressure, such as:
coughing, laughing, sneezing, lifting, or standing up.
Stress incontinence cont…
Stress test - can be performed by patient stand with a
full bladder and cough. The test is positive if urine
leakage coincides with the cough.
Stress incontinence cont…
Common in women due to insufficient pelvic support,
causes:
Childbearing
Gynecologic surgery
Decreased effects of estrogen on tissues of the lower
urinary tract.
Treatment Stress incontinence
Surgical interventions are the most effective
treatments
pelvic muscle exercises can be helpful
Treatment failure is higher in patients who have two
or more leakages per day.
Urge incontinence UI
Urge incontinence also known as detrusor overactivity
(DO), characterized by:
Uninhibited bladder is the most common form of UI in
older adults.
Urinary frequency and nocturnal incontinence are
common.
Urge incontinence UI
Urge incontinence may be
Idiopathic.
Lesions of the central nervous system, stroke.
Bladder irritation from infection, stones, or tumors.
treatment of urge incontinence
Bladder retraining by encouraging the patient to void
every 2 h or based on the patient's symptom
frequency.
The patient can also try urgency control. If no
incontinence for 2 days, the voiding interval can be
increased by 30–60 minutes until the patient is only
voiding every 3–4 h.
treatment of urge incontinence cont…
The anticholinergic drugs
oxybutinin and tolterodine
Patients using tolterodine have a reduced risk of dry
mouth and fewer withdrawals due to side effects.
Mixed incontinence
Mixed incontinence refers to UI where symptoms of
both stress and urge incontinence are present.
Overflow incontinence
Overflow incontinence is due to either bladder outlet
obstruction or an atonic bladder.
patients are Male, but rarely females.
On physical examination, patients may have a palpable
distended bladder.
Causes for both male and fermale
Detrusor atonicity or underactivity can be caused
by
Spinal cord disease
Autonomic neuropathy
Diabetes
Alcoholism
Vitamin B12 deficiency
Parkinson's disease
Tabes dorsalis
treatment Overflow of incontinence
Adrenergic blockers :
Terazosin
Doxazosin
Tamulosin
5-reductase inhibitor – Finasteride
The diagnosis of functional incontinence- individuals who
have UI and have either cognitive or functional
impairments which limit their ability to toilet themselves.
Pressure Ulcers
Pressure ulcers, also known as pressure sores, bedsores, or
decubitus ulcers, occur in older patients with reduced
mobility.
A pressure ulcer occurs when increased pressure between
skin and a bony prominence produces tissue necrosis.
While pressure ulcers can occur anywhere,
Pressure Ulcers cont…
80% of pressure ulcers occur over the heels, lateral
malleoli, sacrum, ischia, and greater trochanters.
Osteomyelitis and sepsis are important, morbid
complications of pressure ulcers.
Pressure Ulcers cont…
Repositioning patients at risk for developing pressure
ulcers every 2 hrs.
Providing bedbound patients mattresses with
pressure-relieving capabilities are standard
interventions to prevent pressure ulcers.
skin
The skin of elderly bruise esily called senile purpura.
Some people have skin like trasparent tissue paper
described as Paparaceous skin especially back of the
hand and forearm.
Postural Hypotension (PH)
Measure to prevent PH
1.Get out of bed slowly and in stages.
2. Sleep with head of bed elevated several inches.
3. Daily fluid intake of 2 to 3 liters.
4. Avoid hot showers or baths, may cause venous
dilatation thereby, venous pooling.
5. Avoid straining at stool. This may cause fall of BP
warning signs of PH (e.g. dizziness, faintness, visual
disturbances)
Postural Hypotension (PH) cont…
6. Avoid bending down and suddenly standing up again.
7. Rest for 60 minutes after meals.
8. Avoid hyperventilation. This lowers the BP.
9. Exercise regimen must be recommended.
10. Use thigh-length elastic stockings to reduce venous
pooling.
11. Avoid prolonged standing.
