Common Mistakes And Misconceptions
| Mistake/Misconception |
Correct Viewpoint |
| Neurocognitive disorder and neurodegenerative disorder are the same thing. |
While both disorders affect cognitive function, they have different underlying causes. Neurocognitive disorder is a broad term that encompasses any condition that affects cognitive abilities, while neurodegenerative disorders specifically refer to conditions where there is progressive damage or loss of nerve cells in the brain. |
| Only older adults can develop these disorders. |
While it is true that aging increases the risk of developing these disorders, they can occur at any age. Certain genetic factors and lifestyle choices such as drug use or head injuries can also increase the risk of developing these disorders at a younger age. |
| A diagnosis means there is no hope for improvement or treatment options available. |
A diagnosis does not mean that all hope is lost; early detection and intervention can improve outcomes for individuals with either disorder. There are various treatments available depending on the specific type and severity of the disorder, including medication, therapy, and lifestyle changes such as exercise and diet modifications. |
| Cognitive decline always leads to dementia or Alzheimer’s disease. |
Not all cases of cognitive decline lead to dementia or Alzheimer’s disease; some may be caused by reversible factors such as medication side effects or vitamin deficiencies which can be treated effectively once identified through proper assessment methods. |
| Neuropsychological testing alone provides an accurate diagnosis for these disorders. |
Neuropsychological testing should only be used as one component in a comprehensive evaluation process which includes medical history review, physical examination, laboratory tests (e.g., blood work), imaging studies (e.g., MRI), family history review etc., since other medical conditions could mimic symptoms associated with neurocognitive/neurodegenerative diseases. |
