Cognitive deficit is an inclusive term to describe any characteristic that acts as a barrier to the cognition process.The term may describe

deficits in overall intelligence (as with intellectual disabilities),
specific and restricted deficits in cognitive abilities (such as in learning disorders like dyslexia),
neuropsychological deficits (such as in attention, working memory or executive function),
or it may describe drug-induced impairment in cognition and memory (such as that seen with alcohol, glucocorticoids, and the benzodiazepines.) Cause
It usually refers to a durable characteristic, as opposed to altered level of consciousness, which may be acute and reversible. Cognitive deficits may be inborn or caused by environmental factors such as brain injuries, neurological disorders, or mental illness. Screening
Screening for cognitive impairment in those over the age of 65 without symptoms is of unclear benefit versus harm as of 2020. In a large population-based cohort study included 579,710 66-year-old adults who were followed for a total of 3,870,293 person-years (average 6.68 ± 1.33 years per person), subjective cognitive decline was significantly associated with an increased risk of subsequent dementia. Treatment
Older people with cognitive impairment appear to improve somewhat with light therapy. Other findings
Although one would expect cognitive decline to have major effects on job performance, it seems that there is little to no correlation of health with job performance. With the exception of cognitive-dependent jobs such as air-traffic controller, professional athlete, or other elite jobs, age does not seem to impact ones job performance. This obviously conflicts with cognitive tests given, so the matter has been researched further.
Nonetheless, one of methyldopas still current indications is in the management of pregnancy-induced hypertension (PIH), as it is relatively safe in pregnancy compared to many other antihypertensives which may affect the fetus. See also
