The Role of Neurocognitive Assessment in Diagnosing Functional Seizures
The Role of Neurocognitive Assessment in Diagnosing Functional Seizures
Functional seizures, sometimes referred to as dissociative or non-epileptic seizures, can be deeply distressing for individuals and families. Many people experience confusion, repeated investigations, uncertainty, or concern that their symptoms are not being fully understood. While diagnosis of functional seizures is typically led by neurology and supported by medical investigations such as EEG and clinical history, neurocognitive assessment can play an important complementary role in understanding the broader cognitive and psychological picture.
Differentiating Overlapping Difficulties
Some cognitive complaints associated with functional seizures may overlap with symptoms seen in anxiety, trauma-related difficulties, depression, sleep disruption, chronic stress, or neurological conditions. Individuals may also experience cognitive changes related to medication, fatigue, or the impact of living with unpredictable episodes.
A structured neurocognitive assessment can help clarify these overlapping factors. It may indicate whether cognitive difficulties appear consistent with attentional disruption, emotional load, fatigue, or other influences requiring further exploration.
This can be valuable in guiding onward treatment and reducing uncertainty.
The Link Between Cognition, Stress, and Functioning
From a neuropsychological perspective, cognition and emotional processes are closely connected. Heightened stress, hypervigilance, trauma responses, or persistent worry about symptoms can significantly affect concentration, memory, and mental stamina.
Assessment can help individuals understand that cognitive difficulties are real, understandable, and often linked to treatable processes rather than permanent decline.
This reframing can itself be an important therapeutic step.
Informing Tailored Intervention
Neurocognitive assessment is not only about clarification; it also informs care planning. Findings may guide recommendations around pacing, stress management, psychological therapy, occupational adjustments, sleep support, or further multidisciplinary input.
Where appropriate, interventions can then target both seizure management and the wider cognitive-emotional impact on daily life.
A Holistic and Compassionate Approach
At The London Neurocognitive Clinic, neurocognitive assessment is approached within a holistic, person-centred framework. We recognise that functional seizures are complex experiences that deserve thoughtful understanding rather than oversimplification. By integrating cognitive, emotional, and contextual perspectives, we aim to help individuals make sense of their symptoms and move towards meaningful support
