Functional Cognitive Disorder vs. Dementia: How Neuropsychological Assessment Can Help
Functional Cognitive Disorder (FCD) is characterised by persistent complaints of memory, attention, or concentration difficulties that interfere with daily life, despite preserved cognitive abilities on standard testing and everyday functioning. Individuals with FCD are often highly attuned to cognitive lapses, interpreting normal slips or stress-related difficulties as signs of serious decline. Anxiety, fatigue, low mood, or heightened self-monitoring commonly amplify these experiences. Importantly, FCD symptoms are real and distressing, but they arise from disrupted cognitive control and attention rather than progressive brain disease.
How Dementia Presents Differently
Dementia involves progressive and consistent cognitive decline linked to structural or neurodegenerative changes in the brain. Unlike FCD, difficulties in dementia typically worsen over time and are evident across multiple contexts, often accompanied by reduced insight into deficits. Memory impairment tends to be less variable and more pervasive, and individuals may struggle to recognise or compensate for their difficulties. Understanding these patterns is essential, yet early-stage dementia can sometimes appear subtle, making careful assessment necessary.
The Role of Neuropsychological Assessment
Neuropsychological assessment provides a detailed, objective evaluation of cognitive functioning across multiple domains, including memory, attention, executive functioning, processing speed, and language. By examining performance patterns rather than isolated scores, neuropsychologists can identify inconsistencies that suggest functional difficulties rather than neurodegenerative change. Assessment also incorporates developmental history, emotional wellbeing, daily functioning, and symptom trajectory, offering a comprehensive understanding of the individual’s experience. This approach allows clinicians to differentiate between conditions that may look similar on the surface but require very different forms of support.
From Clarity to Appropriate Support
Accurate diagnosis has significant emotional and practical benefits. For individuals with FCD, understanding that symptoms are not due to dementia can be profoundly relieving, opening the door to targeted interventions such as psychoeducation, stress management, and strategies to reduce cognitive over-monitoring. For those in whom neurodegenerative changes are identified, early clarity allows timely planning, appropriate medical referral, and supportive interventions that focus on maintaining quality of life. In both cases, neuropsychological insight ensures that individuals receive care that is proportionate, personalised, and clinically appropriate.
Supporting Confidence and Understanding
At The London Neurocognitive Clinic, we recognise how distressing cognitive concerns can be for individuals and families. Our neuropsychological assessments are designed to provide clear explanations, compassionate reassurance, and practical guidance. By distinguishing between Functional Cognitive Disorder and dementia, we help individuals move forward with understanding, confidence, and a clear pathway for support — whatever the outcome of the assessment may be.
