Language
Expressive and receptive language
Also searched as Expressive and receptive language.
In depth
One of the six dsm-5 cognitive domains: producing and understanding speech, reading and writing. The best evidence here comes from post-stroke aphasia recovery, where the pooled result moved written language while overall aphasia severity did not.
What drives it
Brain adaptability increases it.
in cohorts with aphasia, activity in left hemisphere language regions, and possibly a temporal lobe region in the right hemisphere, is positively correlated with language function. Verbatim from the source for this edge — PMC8057712, PMC5487528. PMC8057712
Brain inflammation reduces it.
the impact of sleep deprivation on microglia may be a key factor in cognitive impairment. PMC12868487
Expressive language increases it.
10.1016/j.nicl.2015.10.010 — The DSM-5 Neurocognitive Work Group agreed on six principal domains of cognitive function, each with subdomains. Language comprises object naming, word finding, fluency, grammar and syntax, and receptive language. Taxonomic edge, not a causal mechanism: this is a DSM-5 domain/subdomain relationship, not a pathway acting on another. Sachdev 2014, Nat Rev Neurol 10:634-642 — Classifying neurocognitive disorders: the DSM-5 approach. doi 10.1038/nrneurol.2014.181 The manual's own table pairs the two sides as 'Expressive language and receptive language' (Table 1, doi 10.1186/s13643-019-1220-4); Sachdev's figure names the receptive side only. Scope stated before anyone asks: Sachdev's Figure 2 is an ABRIDGED rendering of the DSM-5 table and does not carry every subdomain named here, so the manual's own wording is cited beside it. doi 10.1016/j.nicl.2015.10.010

What it drives
It increases Memory & focus.
The DSM-5 Neurocognitive Work Group agreed on six principal domains of cognitive function — complex attention, executive function, learning and memory, language, perceptual-motor and social cognition.

It increases Sentence Structure.
Grammar and syntax is a measured subdomain of the language-function cognitive domain. PMID 34896587 · PMC10631800
It increases Word finding.
Word finding sits INSIDE the language domain, so this arrow runs from the domain to a subdomain it contains - it is not a claim that language function is a subdomain of word finding. The taxonomic statement itself is carried the other way round, on the Word Finding → Language Function arrow, which is the direction Sachdev states: 'Word finding' is one of the Language subdomains in Figure 2, alongside object naming, fluency, grammar and syntax, and receptive language. Taxonomic edge, not a causal mechanism. Sachdev 2014, Nat Rev Neurol 10:634-642 — Classifying neurocognitive disorders: the DSM-5 approach. doi 10.1038/nrneurol.2014.181
