FACING THE GIANTS OF<br />

GERIATRICS


GERIATRICS(Nascher1909)<br />

• Geriatric Medicine is that branch <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

general medicine c<strong>on</strong>cerned with the<br />

clinical, preventive, remedial and social<br />

aspects <str<strong>on</strong>g>of</str<strong>on</strong>g> illness <str<strong>on</strong>g>of</str<strong>on</strong>g> older people<br />

• Older people <str<strong>on</strong>g>of</str<strong>on</strong>g>ten have multiple medical<br />

problems, different patterns <str<strong>on</strong>g>of</str<strong>on</strong>g> disease<br />

presentati<strong>on</strong>, <str<strong>on</strong>g>of</str<strong>on</strong>g>ten slower resp<strong>on</strong>se to<br />

treatment and requirements for social<br />

support, calls for special medical skills!


Elderly –pers<strong>on</strong>s aged 65 yrs and<br />

• How are they different?<br />

• Multiple pathology<br />

above(W.H.0.)<br />

• N<strong>on</strong>-specific presentati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> disease<br />

• Rapid decline if not treated early<br />

• High incidence <str<strong>on</strong>g>of</str<strong>on</strong>g> sec<strong>on</strong>dary complicati<strong>on</strong>s<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> disease and treatment<br />

• Need for rehabilitati<strong>on</strong><br />

• Importance <str<strong>on</strong>g>of</str<strong>on</strong>g> social and envir<strong>on</strong>mental<br />

factors


Ger<strong>on</strong>tology<br />

• Ger<strong>on</strong>tology comes from the Greek word<br />

“Geras” meaning old age and “Logo”<br />

meaning Study<br />

• Ger<strong>on</strong>tology is the scientific study <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />

phenomen<strong>on</strong> associated with ageing<br />

• <str<strong>on</strong>g>Geriatrics</str<strong>on</strong>g> is subdiscipline <str<strong>on</strong>g>of</str<strong>on</strong>g> Ger<strong>on</strong>tology<br />

which is related to the medical aspects <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

ageing


Aims <str<strong>on</strong>g>of</str<strong>on</strong>g> Geriatric Medicine<br />

1. To enable elderly people lead full and active<br />

lives<br />

2. To prevent disease or to detect and treat it early<br />

3. To reduce suffering due to disability and disease<br />

and minimise dependence by proper<br />

rehabilitati<strong>on</strong><br />

4. To provide a holistic medical care and arrange<br />

for adequate social support when needed<br />

5.To manage “Geriatric <str<strong>on</strong>g>Giants</str<strong>on</strong>g>” :Inc<strong>on</strong>tinence,<br />

Immobilty, Instability(falls),Intellectual<br />

impairment(dementia)


<str<strong>on</strong>g>Giants</str<strong>on</strong>g> <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>Geriatrics</str<strong>on</strong>g><br />

• <str<strong>on</strong>g>Giants</str<strong>on</strong>g> <str<strong>on</strong>g>of</str<strong>on</strong>g> geriatrics was a term coined by<br />

the late Pr<str<strong>on</strong>g>of</str<strong>on</strong>g>. Bernard Isaacs to highlight<br />

the major illnesses associated with ageing<br />

• Although the major causes <str<strong>on</strong>g>of</str<strong>on</strong>g> mortality in<br />

the elderly are cancers ,heart disease and<br />

stroke, The Geriatric <str<strong>on</strong>g>Giants</str<strong>on</strong>g> reflected the<br />

gigantic numbers <str<strong>on</strong>g>of</str<strong>on</strong>g> elderly afflicted and<br />

the giant <strong>on</strong>slaught <strong>on</strong> the independence<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> the victims!


GIANTS OF GERIATRICS<br />

• IMMOBILITY<br />

• INSTABILITY<br />

• INCONTINENCE<br />

• INTELECTUAL IMPAIRMENT<br />

• IATROGENIC


IMMOBILITY<br />

• Defined as the impairment <str<strong>on</strong>g>of</str<strong>on</strong>g> the ability to move<br />

independently which results in the limitati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> lifespace.<br />

• This difficulty or the inability to perform mobility tasks is<br />

an important outcome to disease and a public health<br />

problem in older people.<br />

• Functi<strong>on</strong>al assessment <str<strong>on</strong>g>of</str<strong>on</strong>g> elderly patients is very<br />

important in a comprehensive geriatric assessment and<br />

management <str<strong>on</strong>g>of</str<strong>on</strong>g> the patient in a holistic manner.


IMMOBILITY<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g>ten multifactorial<br />

• Musculoskeletal-OA----pain, muscle<br />

weakness and dec<strong>on</strong>diti<strong>on</strong>ing<br />

• Heart disease/COPD---CCF----SOB and<br />

loss <str<strong>on</strong>g>of</str<strong>on</strong>g> work ability<br />

• CNS-Stroke—muscle weakness,abnormal<br />

gait ,poor propriocepti<strong>on</strong><br />

• Cataracts-Macular degenerati<strong>on</strong>-poor<br />

visi<strong>on</strong> and falls


IMMOBILITY<br />

Implicati<strong>on</strong>s<br />

• Adversely affects the quality <str<strong>on</strong>g>of</str<strong>on</strong>g> life <str<strong>on</strong>g>of</str<strong>on</strong>g> older people<br />

• Threatens their independence and pers<strong>on</strong>al aut<strong>on</strong>omy<br />

• Increases both the informal and formal career needs and<br />

hence a ‘burden to society’<br />

• Inactivity increases the risks <str<strong>on</strong>g>of</str<strong>on</strong>g> inc<strong>on</strong>tinence, pressure<br />

ulcers, deep vein thrombosis, osteoporosis and<br />

pulm<strong>on</strong>ary embolism<br />

• Increases the risks <str<strong>on</strong>g>of</str<strong>on</strong>g> muscular weakness ,lowered<br />

aerobic capacity and finally leading to poor physical<br />

capacity or dec<strong>on</strong>diti<strong>on</strong>ing


• Impaired Mobility in Older Pers<strong>on</strong>s<br />

• Attending a Geriatric Assessment Clinic:<br />

• Causes and Management<br />

• T L Tan et al Singapore Med Journal 2010<br />

•Impaired mobility is a comm<strong>on</strong><br />

pathway for many diseases, and is associated<br />

with significant functi<strong>on</strong>al decline.<br />

•With proper evaluati<strong>on</strong>, the <str<strong>on</strong>g>of</str<strong>on</strong>g>fending causes<br />

can be identified.<br />

•Early c<strong>on</strong>sultati<strong>on</strong> is important for the<br />

applicati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> appropriate interventi<strong>on</strong> and can<br />

result in better outcome.

IMPROVING MOBILITY


Science News April 2010<br />

... Domestic Robot to Help Sick Elderly Live<br />

Independently L<strong>on</strong>ger<br />

• To enable elderly people to live at home as l<strong>on</strong>g as possible, a<br />

group <str<strong>on</strong>g>of</str<strong>on</strong>g> European researchers, coordinated from Eindhoven<br />

University <str<strong>on</strong>g>of</str<strong>on</strong>g> Technology (TU/e), will link robots and 'smart homes'.<br />

• The robot, a 'sensible family friend', will ensure that home is a nice<br />

place to stay.<br />

• The recently started research project, which has been named<br />

KSERA (Knowledgeable Service Robots for Aging) focuses in<br />

particular <strong>on</strong> COPD patients, people with chr<strong>on</strong>ic obstructive<br />

pulm<strong>on</strong>ary disease.<br />

• In 2030 this disease will be the third cause <str<strong>on</strong>g>of</str<strong>on</strong>g> death worldwide,<br />

according to expectati<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> the <str<strong>on</strong>g>World</str<strong>on</strong>g> Health Organizati<strong>on</strong>.


• A Nao robot. In the KSERA project this standard<br />

robot will be the starting point. It will be<br />

upgraded and fitted with a projector, so that it<br />

can show pictures. (Credit: Image courtesy <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

• 70 year old man with a stroke <strong>on</strong> the right side and<br />

immobile for 3 m<strong>on</strong>ths has after intensive physio and use<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> “Armeo” robotic arm regained some power to move<br />

his right hand up/down and laterally!


CHALLENGES-IMMOBILTY


IMMOBILITY<br />

Case history<br />

• An 85 year old man has a 4cm by 7cm stage 3<br />

pressure ulcer over the sacrum. He has been<br />

c<strong>on</strong>fined to the bed since sustaining a hip<br />

fracture 3 m<strong>on</strong>ths ago and has lost 10 lbs.<br />

during this time. Examinati<strong>on</strong> shows a foul<br />

smelling wound,necrotic tissue covering 50% <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

the ulcer and purulent drainage at the base.<br />

There is no cellulitis—apart from surgical<br />

debridement ---what is the appropriate<br />

,management?


IMMOBILITY<br />

Case history<br />

• Good nutriti<strong>on</strong>—calcium, zinc ,protein intake and<br />

management <str<strong>on</strong>g>of</str<strong>on</strong>g> osteoporosis<br />

• Good medical care and comfortable positi<strong>on</strong>ing, 2<br />

hourly turning and alternating pressure mattresses<br />

• Osteomyelitis, bacteremia and deep vein thrombosis are<br />

complicati<strong>on</strong>s and iv antibiotics and prophylactic<br />

anticoagulati<strong>on</strong> may be required<br />

• After adequate debridement and removal <str<strong>on</strong>g>of</str<strong>on</strong>g> necrotic<br />

tissue <strong>on</strong>ly then adhesive polyurethane dressings and<br />

myocutaneous flap can be c<strong>on</strong>sidered.


INCONTINENCE<br />

• A c<strong>on</strong>diti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> involuntary loss <str<strong>on</strong>g>of</str<strong>on</strong>g> urine that is a social or<br />

hygienic problem and is objectively dem<strong>on</strong>strable.<br />

• <strong>Ageing</strong> causes smaller bladder capacity and greater<br />

night time GFR ---more nocturia in elderly<br />

• Males –urethra obstructed by prostate gland—females<br />

the urethra may be traumatised by frequent pregnancies<br />

• Kidneys become less resp<strong>on</strong>sive to sodium loss and to<br />

ADH –hence the kidneys are less able to c<strong>on</strong>centrate the<br />

urine.


INCONTINENCE<br />

• Adequate functi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the lower urinary tract to store and<br />

empty urine<br />

• Adequate mental functi<strong>on</strong><br />

• Sufficient mobility and dexterity to get to the toilet and<br />

manage the clothing<br />

• Motivati<strong>on</strong> to be c<strong>on</strong>tinent<br />

• Absence <str<strong>on</strong>g>of</str<strong>on</strong>g> envir<strong>on</strong>mental/iatrogenic barriers to<br />

c<strong>on</strong>tinence<br />

ALL THE ABOVE FACTORS MUST BE IDENTIFIED<br />

SO THAT APPROPRIATE MANAGEMENT OF PATIENT!


ACUTE INCONTINENCE<br />

• Delirium<br />

• R estricted mobility<br />

• Infecti<strong>on</strong>,inflammati<strong>on</strong>,impacti<strong>on</strong><br />

• P harmacueticals, polyuria


PERSISTENT INCONTINENCE<br />

• STRESS: the involuntary loss <str<strong>on</strong>g>of</str<strong>on</strong>g> urine during the act <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

laughing, coughing or exercise<br />

• URGE: Leakage <str<strong>on</strong>g>of</str<strong>on</strong>g> urine because <str<strong>on</strong>g>of</str<strong>on</strong>g> the inability to delay<br />

voiding after the sensati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> bladder fullness is<br />

perceived. “ Must go now!!!! Or “ I cannot make it to the<br />

toilet <strong>on</strong> time” are comm<strong>on</strong> complaints.<br />

• OVERFLOW(NEUROGENIC): Frequent dribbling <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

urine, usually after a stroke or BPH<br />

• FUNCTIONAL: Due to physical and cognitive impairment<br />

Dementia, depressi<strong>on</strong>, inaccessible toilet facilities.


INCONTINENCE<br />

• History: medicati<strong>on</strong>s, mental state, mobility<br />

• Physical: CNS, lumbosacral spine, abdomen—<br />

palpable bladder, rectal exam, and vaginal exam<br />

• Post voidal residual urine : >100 MLS –needs<br />

further investigati<strong>on</strong>s and refer for urodynamic<br />

studies---can check for detrusor instability and<br />

compliance <str<strong>on</strong>g>of</str<strong>on</strong>g> urethra<br />

• Urine for microscopy and culture


INCONTINENCE<br />

• Identify and treat c<strong>on</strong>tributing factors—medicati<strong>on</strong>s—<br />

diuretic, tricyclics, anticholinergics, excessive c<str<strong>on</strong>g>of</str<strong>on</strong>g>fee and<br />

tea or alcohol intake.<br />

• Infecti<strong>on</strong> with appropriate antibiotics<br />

• Atrophic vaginitis—treat with oestrogen cream<br />

• Pelvic floor or Kegel exercise, Bladder retraining,<br />

behavioral methods<br />

• Remove barriers<br />

• Medicati<strong>on</strong>s : oxybutinin (direct smooth muscle<br />

relaxati<strong>on</strong>), detrusitol, propiverine hydrochloride<br />

• Devices:Catheters—accurate m<strong>on</strong>itoring <str<strong>on</strong>g>of</str<strong>on</strong>g> urine output,<br />

urinary retenti<strong>on</strong>(BPH), perineal and sacral pressure<br />

ulcers, terminal illness. Inc<strong>on</strong>tinence pads best in stress<br />

inc<strong>on</strong>tinence and also as an adjunct


INCONTINENCE<br />

• Remember that indwelling catheters used <strong>on</strong>ly after<br />

other therapies have been exhausted<br />

• External sheaths or c<strong>on</strong>dom catheters can be tried—not<br />

useful in acute urinary redetecti<strong>on</strong><br />

• Intermittent catheterisati<strong>on</strong> in the younger inc<strong>on</strong>tinent<br />

• Inc<strong>on</strong>tinence carries a HUGE social stigma, reduces life<br />

space and mobility and is a huge financial and social<br />

burden to the carers<br />

• In the management few can be cured, many can be<br />

improved and all can be better understood.

FALLS IN THE ELDERLY


FALLS<br />

Fall defined as a subject unintenti<strong>on</strong>ally coming to rest<br />

<strong>on</strong> the ground, not as a result <str<strong>on</strong>g>of</str<strong>on</strong>g> a major intrinsic event<br />

(e.g.. stroke , syncope) or overwhelming hazard<br />

•Falls are comm<strong>on</strong> and preventable source <str<strong>on</strong>g>of</str<strong>on</strong>g> mortality and<br />

morbidity in the elderly.<br />

•The highest mortality are from falls <strong>on</strong> or from stairs particularly in<br />

the age group <str<strong>on</strong>g>of</str<strong>on</strong>g> 85 years and over.<br />

•Most falls multifactorial in origin resulting from<br />

stability impairment features <str<strong>on</strong>g>of</str<strong>on</strong>g> the host(intrinsic) and extrinsic<br />

causes in the envir<strong>on</strong>ment


•Major sequelae and morbidity <str<strong>on</strong>g>of</str<strong>on</strong>g> falls<br />

•is hip fractures (more comm<strong>on</strong> in<br />

women<br />

with osteoporosis).<br />

•Inability to get up without help.<br />

•Fear <str<strong>on</strong>g>of</str<strong>on</strong>g> falling and loss <str<strong>on</strong>g>of</str<strong>on</strong>g> c<strong>on</strong>fidence.

FALLS IN THE COMMUNITY<br />

MARKEDLY INCREASES WITH AGE<br />

25% AT 70 YEARS OF AGE<br />

35% AT > 75 YEARS OF AGE<br />

• NURSING HOMES : 40% OF ADMISSIONS<br />

WERE DUE TO FALLS<br />

• STUDY BY TINETTI et al;<br />

1 year prospective followup <str<strong>on</strong>g>of</str<strong>on</strong>g> 336 pers<strong>on</strong>s aged<br />

75 years and above 32% fell at least <strong>on</strong>ce<br />

24% had serious injuries<br />

6% had fractures


Risk factors - affecting stability<br />

1. Sensory :<br />

Visi<strong>on</strong>, hearing, vestibular functi<strong>on</strong><br />

2. CNS - problems in central integrati<strong>on</strong><br />

3. Dementia - cognitive functi<strong>on</strong> decline<br />

4. Musculoskeletal<br />

5. Medicati<strong>on</strong>s


Factors which precipitate falls<br />

Majority occurs during ordinary walking, stepping<br />

up or down and while changing positi<strong>on</strong><br />

70% --- FALLS AT HOME<br />

10% --- STAIRS DESCENDING<br />

INTERVENTION TO REDUCE<br />

THE RISK OF FALLING IN THE<br />

COMMUNITY<br />

Tinetti et al, 331 No 13, 1994<br />

NEJM


TARGETED RISK FACTOR<br />

• Postural Hypotensi<strong>on</strong><br />

• Use <str<strong>on</strong>g>of</str<strong>on</strong>g> sedative hypnotic<br />

• 4 prescripti<strong>on</strong> meds<br />

• Unable to transfer safely<br />

• Gait impairment<br />

• Impaired muscle strength


SCREENING FOR PEOPLE AT RISK<br />

• L<strong>on</strong>g acting sedatives<br />

• Mother with hip fracture<br />

• Previous fracture<br />

• Decreased mobility<br />

• > 2 cups c<str<strong>on</strong>g>of</str<strong>on</strong>g>fee/day<br />

• Previous hyperthyroidism<br />

• Poor general health


RISK FEATURES CONTINUED<br />

• Failed “Get up & go” test<br />

• Decreased visi<strong>on</strong><br />

• Resting tachycardia<br />

• Low calcaneal BMD


CHALLENGES-FALLS


PREVENTION OF FALLS(1)<br />

• Older people who have had recurrent falls should be<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g>fered l<strong>on</strong>g term exercise and gait/balance training<br />

• Tai Chi is a promising type <str<strong>on</strong>g>of</str<strong>on</strong>g> balance exercise –reduced<br />

the risk <str<strong>on</strong>g>of</str<strong>on</strong>g> falls during a short period <str<strong>on</strong>g>of</str<strong>on</strong>g> 4 m<strong>on</strong>ths<br />

• When older people at increased falls are discharged<br />

from hospital an envir<strong>on</strong>mental home assessment<br />

should be c<strong>on</strong>sidered<br />

• Patients who have fallen should have their medicati<strong>on</strong>s<br />

reviewed altered or stopped in light <str<strong>on</strong>g>of</str<strong>on</strong>g> their risk <str<strong>on</strong>g>of</str<strong>on</strong>g> future<br />

falls---especially those <strong>on</strong> 4 or more medicati<strong>on</strong>s and <strong>on</strong><br />

psychotropic drugs.


PREVENTION OF FALLS(2)<br />

• Assistive devices like canes ,walkers or hip<br />

protectors may be effective elements <str<strong>on</strong>g>of</str<strong>on</strong>g> a<br />

multifactorial interventi<strong>on</strong> program<br />

• Cardiovascular interventi<strong>on</strong>s in ruling orthostatic<br />

hypotensi<strong>on</strong>, carotid sinus syndrome and<br />

vasovagal syndrome<br />

• Visual interventi<strong>on</strong>—poor acuity,cataracts,<br />

decreased visual field, reduced c<strong>on</strong>trast<br />

sensitivity needs to be corrected.<br />

• Check foot wear—low heeled—hard soled (low<br />

resistance) are better


FALLS IN THE ELDERLY<br />

• Falls are <str<strong>on</strong>g>of</str<strong>on</strong>g>ten predictable<br />

• Screening the populati<strong>on</strong> at risk may be<br />

cost effective<br />

• Interventi<strong>on</strong> can reduce frequency<br />

• Prophylaxis for fractures essential

General Principles<br />

• Drugs should be c<strong>on</strong>sidered as potential<br />

cause <str<strong>on</strong>g>of</str<strong>on</strong>g> any symptom<br />

• ADR presents <str<strong>on</strong>g>of</str<strong>on</strong>g>ten atypically and<br />

n<strong>on</strong>specifically as a “geriatric giant”<br />

– C<strong>on</strong>fusi<strong>on</strong> -- delirium, dementia<br />

– Depressi<strong>on</strong><br />

– Falls<br />

– Inc<strong>on</strong>tinence<br />

– Decreased ADL’s


Why are elderly at risk?<br />

• Changes in drug distributi<strong>on</strong> and metabolism<br />

• Multiple symptoms leading to multiple drugs<br />

• Expectati<strong>on</strong>s -- “pill for every ill”<br />

• Over reliance <strong>on</strong> symptoms rather than<br />

emphasis <strong>on</strong> geriatric assessment<br />

• Multiple factors that affect drug adherence in<br />

the elderly


Why are Elderly at Risk?<br />

• Inadequate clinical assessment:n<strong>on</strong>specific<br />

symptoms are treated with drugs<br />

• Excessive prescribing:polypharmacy<br />

• Altered pharmacokinectics and<br />

phamacodynamics <str<strong>on</strong>g>of</str<strong>on</strong>g> drugs in the elderly<br />

• Compliance


CNS DRUGS AND THE ELDERLY<br />

• Major tranquilizers—elderly are particularly vulnerable to<br />

the side effects e.g.. Delirium, extrapyramidal symptoms,<br />

arrythmias, postural hypotensi<strong>on</strong><br />

• Higher incidence <str<strong>on</strong>g>of</str<strong>on</strong>g> tardive dyskinesia and choreiform<br />

side effects<br />

• DIAZEPAM: t ½ life is 20 hours in young but 90 hrs in 80 yr<br />

old(increased Vd)<br />

• LORAZEPAM(10-20 HRS) and OXAZEPAM(5-15 hrs) no<br />

major changes in elderly<br />

• FLURAZEPAM(7 DAYS), TEMAZEPAM(15 HRS)—<br />

Cerebellar and Fr<strong>on</strong>tal Lobe dysfuncti<strong>on</strong>---predispose to<br />

falls in the elderly


Benzodiazepines<br />

• Depressogenic<br />

• Ataxia --- leading to falls and fractures<br />

• C<strong>on</strong>fusi<strong>on</strong><br />

• Disinhibiti<strong>on</strong> -- aggressi<strong>on</strong> & sexually<br />

inappropriate behaviour<br />

• Withdrawal symptoms<br />

• AVOID l<strong>on</strong>g acting Benzo’s such as<br />

diazepam and flurazepam (except maybe in<br />

alcohol withdrawal)

RECOMMENDATIONS FOR DRUG<br />

THERAPY IN THE ELDERLY<br />

• Make a diagnoses before initiati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> multiple drug<br />

therapy. Avoid treating symptoms!<br />

• Begin with a low dose ;simplify the dose and drug<br />

regimens---maximise compliance<br />

• Advise patients <str<strong>on</strong>g>of</str<strong>on</strong>g> any serious drug effects--<br />

?Potential cause <str<strong>on</strong>g>of</str<strong>on</strong>g> new symptoms<br />

• Periodically review the list <str<strong>on</strong>g>of</str<strong>on</strong>g> medicati<strong>on</strong>s and review<br />

the doses that need to be adjusted with increasing<br />

age<br />

• Advanced patient age, in itself should NEVER be<br />

c<strong>on</strong>sidered a c<strong>on</strong>traindicati<strong>on</strong> to beneficial drug<br />

therapy in older pers<strong>on</strong>s

SUMMARY<br />

SYMPTOMS OF AD<br />

• Progressive deficit <str<strong>on</strong>g>of</str<strong>on</strong>g> memory<br />

• Progressive loss <str<strong>on</strong>g>of</str<strong>on</strong>g> functi<strong>on</strong>al skills<br />

• Behavioral disturbance ,mood disorders<br />

and psychotic problems---arise and<br />

disappear<br />

• Very early signs <str<strong>on</strong>g>of</str<strong>on</strong>g> memory loss and<br />

diminished activity are subtle, <str<strong>on</strong>g>of</str<strong>on</strong>g>ten<br />

overlap with normality


DETRIMENTAL EFFECTS OF AD ON<br />

CAREGIVERS<br />

• PSYCHOLOGICAL(Depressi<strong>on</strong>,anxiety,anger<br />

,resentment,violent behavior)<br />

• PHYSICAL(Increased systolic hypertensi<strong>on</strong><br />

and compromised immune functi<strong>on</strong>)<br />

• MARITAL<br />

• SOCIAL<br />

• FINANCIAL(costs CN$3.9 billi<strong>on</strong> in<br />

1991,??costs <str<strong>on</strong>g>of</str<strong>on</strong>g> informal care)


EARLY DETECTION OF AD<br />

• The accumulati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> warning signs based <strong>on</strong><br />

observati<strong>on</strong>s made by the patient or caregiver<br />

correlates with the progressive nature <str<strong>on</strong>g>of</str<strong>on</strong>g> AD.<br />

• Published practice guidelines have favoured early<br />

detecti<strong>on</strong> and treatment <str<strong>on</strong>g>of</str<strong>on</strong>g> dementia—screening<br />

should not <strong>on</strong>ly be for patients who have suggestive<br />

symptoms but for all elderly pers<strong>on</strong>s<br />

• AD IS NOW RECOGNISED AS AN IMPORTANT<br />

PUBLIC HEALTH PROBLEM THAT HAS<br />

DEVASTATING EFFECTS ON THE PATIENT AS<br />

WELL AS THEIR CAREGIVERS—EARLY DETECTION<br />

IS THE 1 ST IN STEP EFFECTIVE MANAGEMENT OF<br />

AD
