Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Cognitive screening and cognitive assessment are the same thing. | While both involve evaluating an individual‘s cognitive abilities, they differ in their scope and purpose. Cognitive screening is a brief evaluation that provides a general overview of an individual‘s cognitive functioning, while cognitive assessment is a more comprehensive evaluation that assesses specific areas of cognition in greater detail. |
| Only individuals with suspected cognitive impairment need to undergo neurocognitive assessments. | Neurocognitive assessments can be useful for anyone who wants to gain insight into their cognitive strengths and weaknesses or track changes in their cognition over time. They can also be helpful for identifying early signs of dementia or other neurological conditions before symptoms become apparent. |
| Neurocognitive assessments are only necessary for older adults. | While age-related declines in cognition are common, neurocognitive assessments can be beneficial for individuals of all ages who have concerns about their cognitive functioning or want to optimize their brain health. Additionally, some neurological conditions may present earlier in life and require early intervention to prevent further decline. |
| A high score on a neurocognitive assessment means there is no cause for concern regarding one’s cognition. | While a high score on a neurocognitive assessment may indicate strong performance on the tasks assessed, it does not necessarily mean that an individual has optimal brain function overall or will not experience future declines in certain areas of cognition due to aging or other factors such as injury or illness. |
| Neurocognitive assessments provide definitive diagnoses. | While neurocognitive assessments can provide valuable information about an individual’s cognitive functioning, they do not provide definitive diagnoses without additional clinical information from medical history, physical exams, imaging studies (e.g., MRI), laboratory tests (e.g., blood work), and/or consultations with specialists such as neuropsychologists or neurologists. |
