What is Dementia?
5
Dementia
  • A group of symptoms
  • Memory loss
  • Problems with reasoning, judgment, language
  • AND
  • Problems with day to day functioning (work,
    driving, social relationships)
  • AND
  • A progressive illness

6
Symptoms of Dementia
  • Problems with short term memory
  • Appointments
  • Conversations
  • Events
  • Repeating stories
  • Difficulty remembering names, faces
  • Forgetting acquaintances and friends

7
Symptoms of Dementia
  • Trouble making sense of language
  • Trouble finding the right word
  • Difficulty naming objects
  • Understanding complicated instructions
  • Trouble doing familiar things
  • Driving, banking
  • Cooking, cleaning, laundry
  • Dressing, bathing

8
Symptoms of Dementia
  • Confusion in unfamiliar places
  • Getting lost
  • Personality changes
  • Easy to anger, emotional
  • Suspicious
  • Seeing or hearing things that arent there

9
Dementia or Normal Aging?
  • Normal changes of aging
  • Slower to process information
  • Hearing and vision may decrease
  • Motor speed decreases
  • Unlike dementia, these changes should not prevent
    normal day-to-day activities

10
Other things that cause memory trouble
  • A recent medical illness
  • Starts suddenly
  • Changes between sleepy and agitated
  • Depression
  • Sad mood
  • Decreased initiative
  • Some medical conditions
  • Vitamin deficiencies
  • Low thyroid function
  • Sleep Apnea

11
Mild Cognitive Impairment
  • Somewhere between memory changes of normal aging
    and dementia
  • Can affect memory, or other domains or both
  • Increases the risk of getting dementia BUT not
    everyone who has MCI will go on to develop
    dementia

12
Causes of Dementia
  • Alzheimers Dementia
  • Most common form of dementia
  • 10 of 65-75 year olds
  • 20 of 75-85 year olds
  • 30 of gt 85 year olds
  • Gradually progresses over time
  • Cause not known for sure
  • Genetics in some families (more rare)
  • Messenger chemicals and inflammation in the brain
  • Brain gradually losses size (atrophy)

13
Causes of Dementia
  • Vascular dementia
  • Second most common type of dementia
  • Caused by small strokes
  • Areas of brain that have stopped getting oxygen
    and die
  • The strokes might not have other symptoms
  • Strokes happen suddenly and cause sudden
    worsening of memory

14
Causes of Dementia
  • Mixed Dementia
  • Combination of Alzheimers and Vascular
  • Very common
  • Gradual decline with occasional sudden worsening
  • Frontal Temporal Dementia
  • Often has personality changes early on
  • Parkinsons Disease related Dementia
  • Others

15
What Are the Risk Factors for Dementia?
16
Risk Factors
  • Genetic
  • Vascular
  • Lifestyle

17
Family History
  • Most cases of dementia are NOT genetic, inherited
    or running in the family
  • Some cases of dementia run in the family where
    multiple members in several generations have
    dementia
  • Often dementia comes on at younger age
  • Can come on at older age and look like usual
    Alzheimers disease

18
Cardiovascular (Heart and Blood Vessels)
  • High blood pressure
  • High cholesterol
  • Diabetes
  • Smoking
  • All of these increase the
  • risk of stroke
  • These are risk factors for both AD and vascular
    dementia
  • What can do to help with this?
  • Exercise, healthy diet, quit smoking
  • Managing the above medical conditions well

19
Lifestyle
  • Potential Lifestyle factors
  • Traumatic head injuries
  • Toxic exposures
  • Physical activity / Diet
  • Education

20
Diagnosing Dementia
21
How is it DIAGNOSED?
  • The only true way is to test a sample of the
    brain
  • This cannot be done in a live person!
  • Doctors are researching ways to diagnose dementia
    using brain scans and other tests
  • The diagnosis is made by your doctor
  • Talking to the patient and family
  • Physical examination
  • Brain scans and laboratory tests in some cases

22
What happens at the doctor's office?
  • Talking to the patient and family
  • Memory changes
  • Trouble doing day-to-day activities
  • Safety concerns
  • Driving
  • Getting lost
  • Burning pots on the stove, leaving taps on to
    flood
  • Other medical conditions
  • Conditions that increase the risk of dementia or
    stroke
  • Medications that could make memory worse
  • Pain medications, sleeping pills, alcohol
  • Depression
  • Family history of dementia

23
What happens at the doctors office?
  • Physical Examination
  • Checking for signs of stroke, Parkinsons or
    other conditions that cause dementia
  • Memory Testing
  • The Mini-Mental test
  • Written test of memory and thinking
  • The doctor may also do other memory tests

24
What happens at the doctors office?
  • Investigations
  • Usually blood work is done to make sure there
    isnt a medical cause for the memory change
  • Blood work to check vitamins and thyroid levels
  • Imaging
  • CT or MRI scans
  • Not every person needs a head scan
  • Scans are only done if there are signs of stroke,
    bleeding in the brain or other worrisome signs

25
Diagnosis of Dementia
  • No one test can diagnose dementia
  • Memory tests or brain scans alone are not enough
  • Diagnosis is made after combining the medical
    assessment and memory tests

26
How to Prevent Dementia?
27
Prevention - Without Drugs
  • Exercise the brain
  • Exercise the body
  • Keep socially active
  • Quit smoking
  • Alcohol in moderation
  • Wear a helmet and avoid hitting your head
    (sports)

31
Prevention With Drugs
  • May be helpful
  • Omega 3 acids
  • May be harmful
  • Vitamin E and estrogen may increase heart
    attack and stroke
  • Anti-inflammatories heart and kidney side
    effects
  • Ginkgo biloba may increase bleeding
  • Preventing strokes
  • Keep good control of blood pressure, diabetes and
    cholesterol
  • Baby aspirin in people with risk of stroke ask
    your doctor

37
Medical treatment
  • No medication can CURE dementia
  • Medication may slow down the dementia
  • In some people medication does not work at all
  • Some people cannot take medication because of
    side effects
  • Medication is started when memory changes
    interfere with day-to-day activities
  • What medication can do
  • Make people a little more organized and able to
    function day-to-day
  • May not actually improve memory

38
Medical treatment
  • Cholinesterase Inhibitors
  • Approved for Alzheimers, Vascular, Mixed and
    Parkinsons Dementias
  • Donepezil (Aricept), Rivastigmine (Exelon),
    Galantamine
  • Side effects include nausea, diarrhea, slow heart
    beat and dizzy spells
  • Memantine (Ebixa) is also used in more severe
    Alzheimers
  • Has side effects such as dizziness, and can
    worsen aggression and confusion

39
Living with Dementia
40
Planning for the Future
  • Involve family and close friends and explain
  • The diagnosis
  • The persons memory will decline
  • The person will need more help over time
  • Plan for the future while the person can still
    talk about what they prefer
  • Living Arrangements
  • Health Care
  • Substitute Decision Maker who will make medical
    decisions if the person becomes unable
  • Advance Directives a written document about
    medical preferences

41
Finances
  • Understand their financial situation
  • Bank accounts
  • Income
  • Assets (home)
  • Debt
  • Will
  • Power of Attorney
  • Assigns a person to take over finances if they
    become unable to manage

42
Driving
  • When to stop?
  • Who can help?

43
Wandering
  • Pacing around
  • Can get lost or fall
  • Ways to manage
  • Close supervision
  • Provide a safe place to wander (mall)
  • Provide alternative activities
  • Environment control
  • Lock doors
  • Remove hazards
  • Maintaining contact
  • Wandering registry Safely Home, GPS, cell phones

44
Tips For Caregivers Safety Measures at Home
  • Locks on medicine cabinets
  • Locks for stove

  • Take care of your own medical problems
  • Consider respite care and outside supports
  • Respite through care facilities
  • Home Care
  • Adult Day Centers
  • Connect with other caregivers through the
    Alzheimers Society of BC

46
News Flash - What is new in the Dementia World?
47
Diagnosis of Dementia
  • New techniques show how the brain is working
  • PET, SPECT scans
  • More accurate and detailed scans
  • Early on may predict who is at risk of developing
    Alzheimers disease
  • May help to tell different types of dementia apart
  • Mostly used in research
  • Soon could be used routinely

48
Diagnosis of Dementia
  • Biomarkers
  • Clues from cerebrospinal fluid (CSF), fluid
    around the brain
  • Take a sample of the fluid
  • Must stick a needle into the back to collect the
    fluid
  • Invasive test with some risks
  • May be able to predict who among those with mild
    memory problems will eventually get Alzheimers
    Disease
  • Only used in research right now
  • Soon could be used routinely

49
Treatment of Dementia
  • There is currently no cure for any type of
    dementia
  • Researchers are working hard on new treatments
    and ways to prevent dementia
  • Vaccines
  • New medications
  • New treatments may be ready as early as 5 10
    years from now

50
Take Away Points

51
Take Away Points
  • Risk factors
  • Cardiovascular
  • Genetics
  • Prevention
  • Healthy diet and exercise
  • Social activities
  • Controlling medical conditions
  • Prevent strokes

52
Take Away Points
  • Diagnosis of dementia is done by a doctor and
    involves
  • Talking with a patient and their family,
  • A physical exam
  • Memory testing
  • In some cases blood or imaging tests

53
Take Away Points
  • Treatment of dementia involves
  • Support systems for the patient and caregivers
  • Medication
  • Safety and planning for the future are important
  • The Alzheimers Society is wonderful resource for
    families
