Dementia Flashcards
features of Lewy body dementia
> 65
gradual decline
pathophysiology of Lewy body dementia
deposits of protein a-synuclein in neurones, interferes with signals
specific symptoms to lewy body dementia
difficulty learning new things
disturbed sleep
hallucinations
treatment of dementia
speech and language therapy
cognitive stimulation
memory cafes
physio
meds to reduce symptoms
symptoms of dementia
confusion
memory loss
features of Alzheimers
> 65
gradual decline, affects short term memory first as hippocampus affected
pathophysiology of Alzheimers
beta amyloid plaques get between neurones, impair brain function
and 3R + 4R tau proteins tangle inside neurones
=apoptosis of neurones
what causes the cognitive symtypoms of Alzheimers?
decreased ACh in nucleus basalis
risk factors for alzheiers
familial- early onset
down’s syndrome
APOE-e4
features of vascular dementia
> 65
decline after each stroke to lose more functions
multi infarct dementia
pathophysiology of vascular dementia
progressive loss of brain function from atherosclerosis
=chronic ishcaemia
=ischaemic stroke
=liquefactive necrosis
=loss of brain function
features of frontotemporal dementia
40-60
memory spared at first, but behavioural symptoms
pathophysiology of frontotemporal dementia
pick bodies (tangles of 3R tau protein) = apoptosis
atrophy of frontal then temporal lobes
