Functional cognitive disorders are a group of over-lapping conditions in which cognitive symptoms are present, which are genuine, distressing, and often disabling, but experienced inconsistently and not related to systemic or brain disease (panel).
What is cognitive and functional impairment?
Functional cognitive disorder (FCD) is an under-recognised condition that is different from dementia. In FCD, cognitive difficulties with memory and thinking – particularly when the person can’t maintain attention – are down to a problem with how the brain is working, rather than to loss of brain cells.
Can functional neurological disorder cause memory loss?
FND can include sensory symptoms, such as numbness, tingling or pain; cognitive symptoms like memory loss or difficulty concentrating; and motor symptoms, including involuntary tremor or trouble initiating actions. Some people with FND also experience seizures or fainting.
Is functional neurological disorder permanent?
Typically these disorders affect your movement or your senses, such as the ability to walk, swallow, see or hear. Symptoms can vary in severity and may come and go or be persistent. However, you can’t intentionally produce or control your symptoms. The cause of functional neurologic disorders is unknown.
What is a functional cognitive disorder?
Functional (psychogenic) cognitive disorders: a perspective from the neurology clinic. They can be included under the umbrella of functional neurological disorders, one of the most common causes of neurological disability.
What are the symptoms of mild cognitive impairment?
It’s characterized by problems with memory, language, thinking or judgment. If you have mild cognitive impairment, you may be aware that your memory or mental function has “slipped.” Your family and close friends also may notice a change. But these changes aren’t severe enough to significantly interfere with your daily life and usual activities.
Is there a questionnaire to distinguish functional memory disorders from dementia?
Patients with functional cognitive complaints have significantly higher scores than healthy controls, and there is good test–retest reliability. However, this questionnaire has not been validated to distinguish functional memory disorders from mild cognitive impairment or early dementia.
What are the diagnostic criteria for functional neurological symptom disorder?
The diagnostic criteria for functional neurological symptom disorder require motor or sensory symptoms that are incompatible with recognised neurological or medical conditions, cannot be better explained by an alternative diagnosis and cause significant distress or functional impairment.
