Functional neurological disorder (FND) causes real, often disabling symptoms — weakness, shaking, seizure-like attacks,
numbness or speech problems — because the brain has trouble sending and receiving signals, even though scans show no
damage. The old word “hysteria” wrongly implied the symptoms were imagined or deliberate, and mostly affected women.
They are neither. FND is common, and it can improve with the right treatment.
What is FND?
A helpful comparison is a computer with a software problem rather than broken hardware: the nerves, spine and brain
are structurally healthy, but the way the brain controls movement and processes sensation isn't working properly.
FND is one of the most common reasons people see a neurologist. The symptoms are genuine and not under voluntary
control — the person is not “putting it on”.
A first seizure, sudden weakness, or loss of speech always needs urgent medical assessment
(108 / 112) to rule out stroke, epilepsy and other conditions before FND can be considered.
Daylight, gentle movement and a steady daily routine support mood, sleep and energy — alongside, not instead of, professional care.
Types of symptoms
Common symptoms of functional neurological disorder
Type
Examples
Functional seizures
Attacks that look like epileptic seizures or faints, often with shaking or unresponsiveness (also called dissociative or non-epileptic seizures)
Movement
Weakness or paralysis of a limb, tremor, jerks, walking difficulty, abnormal postures
Sensory
Numbness, tingling, loss of feeling on one side
Speech & swallowing
Slurred or halting speech, loss of voice, a feeling of a lump in the throat
There is usually no single cause. Things that make FND more likely include a physical trigger such as an injury,
illness, migraine or surgery; long-term stress; past traumatic experiences; anxiety and depression; and other
neurological conditions — about 1 in 5 people with functional seizures also has epilepsy. Many people with FND have
no psychological difficulties at all, which is why the older idea that it is “all stress” is misleading.
Diagnosis
A neurologist diagnoses FND from positive signs in the examination — for example, weakness that
changes in a characteristic way with distraction (Hoover's sign) — not simply because tests are normal. Scans and an
EEG may be done to check for other conditions, and video recordings of attacks are very helpful. A clear explanation
from the doctor is itself an important part of treatment.
Treatment
Understanding the diagnosis — knowing the symptoms are real, common and potentially reversible
Specialist physiotherapy — retraining movement using distraction and automatic movements; effective for functional weakness and walking problems
Psychological therapy — CBT and related therapies help with functional seizures and with coping
Speech and occupational therapy for speech, swallowing and daily activities
Treating pain, sleep problems, fatigue, anxiety and depression
For people wrongly treated for epilepsy, careful withdrawal of anti-seizure medicine under a neurologist
For families
Believe the person — the symptoms are not faked, and blame makes them worse.
During a functional seizure: keep them safe, stay calm, don't restrain them, and talk reassuringly. Follow any seizure plan the neurologist gives.
Encourage gradual return to normal activities rather than prolonged rest.
Avoid rituals or treatments that frighten the person or treat the symptoms as possession — they cause harm and delay recovery.

Ayurvedic view
Calm Vata and the mind (Manas) → reduce Rajas and Tamas → rebuild Ojas → routine, rest and counselling (Sattvavajaya).
Ayurveda places the mind at the centre of health and describes conditions where emotional strain disturbs bodily
function, attributed to Vata disturbing the channels of the mind (Manovaha srotas) with increased
Rajas and Tamas and depleted Ojas. Its approach — reassurance and counselling
(Sattvavajaya chikitsa), regular routine, sleep, nourishing food and calming therapies — can sit comfortably
alongside neurological rehabilitation.
Supportive care & safety
Warm-oil massage (abhyanga), Shirodhara and slow breathing may help relaxation and sleep.
Brahmi, Ashwagandha and Jatamansi are used by practitioners for stress; they can add to sedating medicines.
Supportive therapies should encourage activity and recovery, not long periods of rest.
Use licensed products from a qualified practitioner, and keep your neurologist informed.
