dementia Flashcards
difference between Alzheimer’s and dementia
Alzheimer diagnosis is decline in 2 or more cognitive domain while dementia is decline in at least one
name 6 neurocognitive domains
complex attention learning and memory executive function perceptual motor language social cognition
mild neurocognitive disorder
evidence of modest cognitive decline
cognitive deficits are insufficient to interfere with independence
cognitive deficits do not occur exclusively in the context of delirium-same as major
cognitive deficits are not primarily attributable to another mental disorder- same as major
characteristics of Alzheimer’s
decline in short term memory
depression early on
persecutory accusation
personality changes
Gross neuropathology changes
cerebral cortex shrinkage
enlarged ventricles
neuronal loss- degeneration and loss of synaptic connectivity
histological changes in Alzheimer’s
plaques- sticky proteins called beta- amyloid between nerve cells
neurofibrillary tangles- inside dying cells (twisted fibers of a protein called tau)
list the risk factors for Alzheimer’s
age family history down syndrome head injury Fam history of Parkinson's depression epilepsy encephalitis/meningitis herpes
special investigations of dementia
TSH, VDRL, FBC, Renal & Hepatic function, Ca2+.
Phos, B12, Folate, CXR, PSA, HIV, EEG, CT scan
management for some Alzheimer’s
cholinesterase inhibitors
donepezil
galantamine
rivastigmine
vascular dementia risk factors
smoking hypertension diabetes previous CVA, TIA, MI IHD, PVD
Features of vascular dementia
personality preserved
step-wise deterioration
