Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'когнитивное нарушение' in everyday speech; it sounds excessively clinical. In general contexts, 'проблемы с памятью / мышлением' (memory/thinking problems) is more natural.
- Do not confuse with 'умственная отсталость' (intellectual disability), which is a different, usually congenital condition.
Common Mistakes
- Using 'cognitive impairment' to describe temporary confusion (e.g., from lack of sleep).
- Spelling error: 'cognative impairment'.
- Using it as a countable noun incorrectly: 'He has a cognitive impairment' (correct) vs. 'He has cognitive impairments' (possible but less common for general state).

Frequently Asked Questions
No. Dementia is a type of severe, progressive cognitive impairment that significantly interferes with daily life. 'Cognitive impairment' is a broader term that includes milder forms (Mild Cognitive Impairment - MCI) that may not progress to dementia.
Typically, the term implies a more persistent condition. Temporary states caused by fatigue, intoxication, or acute illness are usually not labelled 'cognitive impairment' in a formal medical sense.
Cognitive impairment generally refers to a *decline* or loss of previously acquired cognitive abilities. Intellectual disability (formerly mental retardation) is a developmental condition present from birth or early childhood, characterized by limitations in intellectual functioning and adaptive behaviour.
Through a combination of medical history, physical exams, laboratory tests (to rule out other causes), and standardized neuropsychological tests that assess memory, language, reasoning, and other cognitive domains.
