Dementia Types – Alzheimer’s
16
Vascular Dementia

Winston Churchill Age 65: Lord of Admiralty; Prime Minister Age 79: Nobel Prize, Literature Age 84: finishes History of English Speaking People
18
Vascular Dementia Loss of brain functions due to the accumulation of small strokes or other cell loss due to inadequate blood flow Dementia types - Vascular Difficulty with decisions first Then ↓ short term memory
19
The presence of brain amyloid may not be enough to cause Alzheimer Disease. (JAMA 1997; 277: 813) None 57% Large infarcts 75% Lacunar infarcts93% The Nun Study. Brain Pathology: 61 had amyloid plaques and tangles (signs of Alzheimer’s) Some also had additional vascular disease How many of the 61 Nuns had Alzheimer’s dementia? Vascular lesions % Dementia
20
“Mixed Dementia” May be the most common form of dementia in the USA
21
Brief periods of confusion Visuospatial dysfunction Incoordination or abnormal muscle control: Falls Sleep disorder: central regulation of consciousness Hallucinations …a tau protein abnormality Guy M. Arch Neurology 58:1803 Memory may be unimpaired Dementia Types – Lewy Body Dementia with Lewy Bodies (DLB)
24
Dementia Types – Frontotemporal Lobe Personality change Loss of social inhibition Apathy (not depression ) Memory may be unimpaired
26
Alcohol Related Dementia Normal thiamine, no vitamin deficiencies May be noticed years after drinking stopped Characterized by pre-frontal, frontal lobe signs: poor decision making; retained semantic and ST memory; loss of personal geographic place skills Variable course, often very slow loss

Issues When to Start/Stop Medications How to Protect Financial Resources How to Diagnose Alzheimer’s (and biomarkers) What to do with Mild Cognitive Impairment Is the coalition of NIH, Big Pharma, & Academic Researchers In the public’s best interest? How should we prepare for the expected increase in dementia from traumatic brain injuries? Terminal Care Pacemakers/ICDs Feeding tubes Who determines reimbursement for (and controls) medications and long term care?
