ICD-11 Criteria for Frontotemporal Dementia (6D83)
Frontotemporal dementia (FTD) is a
group of primary neurodegenerative disorders primarily affecting the frontal
and temporal lobes. Onset is typically insidious with a gradual and worsening
course. Several syndromic variants (some with an identified genetic basis or
familiality) are described that include presentations with predominantly marked
personality and behavioral changes (such as executive dysfunction, apathy,
deterioration of social cognition, repetitive behaviours, and dietary
changes),predominantly language deficits (that include semantic,
agrammatic/nonfluent, and logopenic forms), predominantly movement-related
deficits (progressive supranuclear palsy, corticobasal degeneration, multiple
systems atrophy, or amyotrophic lateral sclerosis), or a combination of these
deficits. Memory function, often remains relatively intact, particularly during
the early stages of the disorder.
Coding
Note: This
category should never be used in primary tabulation. The codes are provided for
use as supplementary or additional codes when it is desired to identify the
presence of dementia in diseases classified elsewhere.
When dementia is due to multiple aetiologies, code all that apply.
