Functional Neurological Disorder (FND) : a patient's guide

including Functional/Dissociative (non-epileptic) Seizures,  Functional Movement Disorder and other functional symptoms



Tiredness is a very common symptom in patients with functional neurological symptoms.


Often despite many more obvious symptoms, people say that it is the tiredness and fatigue that really holds them back day to day.


Tiredness in this situation can also be thought of as another symptom related to a problem with nervous system functioning.


When tiredness like this occurs

•with no other neurological symptoms

•for more than 6 months

• not due to a detectable underlying medical or neurological condition

then it is called Chronic Fatigue Syndrome / M.E. (CFS/ME)


CFS/ME has been recognised as a genuine illness by the Chief Medical Officers in England/Wales and Scotland (link)


This website is not designed to discuss chronic fatigue syndrome / M.E. in detail


Fatigue may occur as part of anxiety or depression, although its important to say that you don’t need to be anxious or depressed to have persistent and severe fatigue


However, many of the principles of treating CFS/ME which have been proven to be effective in clinical trials are likely to be effective in patients with functional neurological symptoms


there is more information at NHS Direct


Services for patients with CFS/ME are patchy. However, they may be better than services for people with functional neurological symptoms. You may wish to find out from your doctor whether there is a treatment service locally for CFS/ME as this may be a route to treating your other symptoms.

Stories of recovery from Chronic Fatigue Syndrome (CFS/ME)

Dr Henrik Vogt is a Norwegian general practitioner with a research interest in functional disorders.


CFS/ME describes persistent and disabling fatigue, usually with many other symptoms such as poor concentration. There are many online personal stories testifying to how horrendous life with CFS/ME can be.


But patients faced with CFS/ME have often found it hard to find stories of recovery from which they might learn.


Dr Vogts website Recovery Norway - - aims to publishing stories of improvement which may be helfpul to some readers of this website to try to redress the balance.
