NP: Chapter 20 Frontotemporal Dementia Flashcards
frontotemporal dementia =
progressive neurodegenerative disorder, develops before the age of 65 years
what is the most common type of dementia after alzheimers
vascular dementia
what is the most common clinical manifestation of ftd
the behavioural variant.
behavioural variant frontotemporal dementia (bv-ftd)
changes in personality and social behaviour, cognitive impairments, language impairments
changes in personality bij bv-ftd
decreased emotional involvement
emotional blunting
lack of initiative
apathy
impaired judgement
hyperactivity
restlessness
wat gebeurt er met language bij bv-ftd
in early stages, language remains fluent.
but in later stages: economy of speech, whcih means that the patients tend to speak less as the disease advances. they initiate less conversation, and answer with yes/no. eventually may become mute
3 types of bv-ftd
- profile of disinhibition, hyperactivity and distractability
- profile of apathy, behavioural withdrawal, lack of initiative
- profile with stereotypy and compulsive behaviour
ftd met mdn
frontotemporale dementie met motorneuronziekte (dus normale ftd + de manifestaties van motorische neuronziekte zoals neurogene spieratrofie)
3 subtypes of frontotemporal dementia
behavioural variant
progressive non-fluent aphasia
semantic dementia
behavioural variant =
- deterioration in social behaviour + emotional blunting and anosognosia (loss of insight)
- impairment in regulation of personal behaviour at an early stage
- increasing neglect of personal care
- speech and language impairment
progressive non-fluent aphasia
non fluent speech: agrammatism, phonemic paraphrasias, word finding problems
wat hebben mensen met pnfa niet
no behavioural or cognitive dysfunctions.
(heel soms tijdens eindfases wat behavioural)
semantic dementia
prominent verbal or visual semantic impairments which are often manifested as a fluent, empty speech and word finding problems.
visuo-perceptual impairments
initially no impairments in other domains
kijken naar prevalentie model dementias in docs
oke
wanneer is de onset van ftd
before the age of 65, and peaks between 50 and 60
about 10% of patients are above 70 years
oke
what is the average duration of the disease
8 years (3 years for ftd-mnd)
prevalence of ftd
ongeveer 20 per 100.000 ppl
genetics of ftd
40%
waar is een autosomal dominant inheritence pattern gevonden
bij bv-ftd (minder bij sd en pnfa)
welke genes bij ftd
MAPT gene, progranulin (GRN) and C90RF72
welke proteins bij ftd
tau, tdp-43 and fus
waar zie je atrophy bij bv ftd
frontal and or temporal, soms hippocampal.
bij early stages wat kan je zien bij ftd
not geen atrophy, dan via spect or pet scan kijken
pnfa wat zie je
assymetrical atrophy: left frontotemporal region
wat zie je bij sd
temporal lobe atrophy and hippocampal atrophy
welke cognitive domains affected by bv ftd
attention
concentration
executive functions
abstract thinking
language
wat voor impairments nog meer bij bv ftd
sociocognitive functioning; such as emotion perception and theory of mind, en planning, organizing,, structuring and mental flexibility
wat is lastig bij deze patienten met testen
patients are willing to be tested, but easily distracted and only minimal effort (=economy of effort).
poor insight into performance and effort
= daardoor missing test results
responses of bv ftd are often…
arbitrary, impulsive, and lacking in basis/arguments
wat blijft unaffected bij bv ftd tot de advanced stages of the disease
memory and orientation
pnfa main symptoms
hestitation, stuttering use of language (flagging?)
insight in disease bij pnfa
goed, want patienten proberen zichzelf te corrigeren.
wat is nog meer impaired bij pnfa
ook reading and writing. other cogn domains remain unimpaired until the final stages
wat is bij semantic dementia de main symptoms
comprehension of the meaning of the content of words, naming things etc. ook soms visual agnosia (geen voorwerpen herkennen).
wat remains intact bij sd
repetition of words, and sentences. memory voor een groot deel ook, behalve de semantic memory. autobiografie blijft meestal goed.
