A Guide for You: Understanding Functional Neurological Disorders

A guide for young people and the adults who support them

Functional Neurological Disorders (FND) are real, common, and treatable conditions that affect how the brain and body communicate. They sit at the intersection of neurology and psychology because the brain’s normal communication pathways become disrupted in how they function.

Two types of FND that many young people experience are:

• NEAD (Non‑Epileptic Attack Disorder)

• Functional tics

Both can look and feel like neurological conditions such as epilepsy or Tourette syndrome, but they work differently and need a different approach to support and recovery.

What does “functional” actually mean?

Think of the brain as a brilliant, busy control centre. In neurological conditions, there is a structural or electrical problem, something physically different in the brain or nerves.

In functional conditions, the structure is normal, but the functioning becomes disrupted. The brain is still healthy, but the communication systems that control movement, sensation, or awareness start sending signals in a less reliable way.

This is why symptoms are real, involuntary, and often very frightening: but also why recovery is absolutely possible.

NEAD (Non‑Epileptic Attack Disorder)

What it looks like

NEAD episodes can look very similar to epileptic seizures: shaking, loss of awareness, collapsing, or becoming unresponsive.

How it differs from epilepsy

• In epilepsy, seizures are caused by abnormal electrical activity in the brain.

• In NEAD, the brain’s electrical activity is normal during an episode. The problem lies in how the brain processes stress, sensory information, and automatic responses.

Why NEAD happens

NEAD often develops when the brain becomes overwhelmed—sometimes by stress, sometimes by physical illness or pain, sometimes by a build‑up of pressures that the young person may not even recognise. The brain shifts into a protective “shutdown” or “overload” mode.

This is not deliberate. It is not attention‑seeking. It is not the young person’s fault.

Functional Tics

What they look like

Functional tics can include sudden movements, sounds, or words that feel hard to control. They may appear quickly, change rapidly, or be influenced by social or emotional situations.

How they differ from Tourette syndrome

• Tourette syndrome is a neurodevelopmental condition with a typical pattern of onset in early childhood.

• Functional tics often start later, may be more dramatic or complex, and can be linked to stress, anxiety, or copying behaviours seen in peers or online.

Why functional tics happen

The brain becomes highly tuned to certain movements or sounds, and they become “learned” automatic responses. The more attention the brain gives them, the stronger they can become—much like a habit loop.

Again, this is not chosen behaviour. It is a brain‑body communication issue.

Why do these conditions occur?

There is rarely one single cause. Instead, several factors can combine:

• Stress or emotional overload

• Physical illness, pain, or fatigue

• Difficult life events

• High expectations or pressure

• Neurodivergence (e.g., ADHD, autism)

• Social influences, including online content

• A sensitive or highly responsive nervous system

Young people are especially vulnerable because their brains are still developing, and they often carry invisible pressures from school, friendships, family life, and identity.

The most important message

These conditions are real. They are common. And with the right support, young people can get better.

Diagnosis is the first step. Understanding what is happening reduces fear and gives back a sense of control.

What helps?

A wellbeing‑centred, strengths‑based approach

There is no single “quick fix,” but recovery is absolutely possible. The most effective approach focuses on:

1. Calming the nervous system

• Regular routines

• Sleep support

• Gentle physical activity

• Breathing and grounding techniques

• Reducing sensory overload

2. Understanding triggers

Noticing patterns—stress, tiredness, conflict, busy environments—helps young people predict and manage symptoms.

3. Building emotional resilience

Therapeutic support can help young people understand their feelings, develop coping strategies, and feel more in control.

4. Re‑training the brain

For NEAD:

• Staying calm during episodes

• Reducing avoidance

• Gradually returning to normal activities

For functional tics:

• Redirecting movements

• Reducing attention to tics

• Strengthening alternative habits

5. Supportive adults

Carers, teachers, and family members play a huge role by:

• Staying calm

• Avoiding panic responses

• Encouraging normal routines

• Keeping expectations steady and realistic

• Reinforcing the message that recovery is possible

A hopeful outlook

Young people with FND, NEAD, or functional tics can and do get better. Many recover fully. Others learn to manage symptoms so they no longer interfere with daily life.

The key ingredients are:

• The right diagnosis

• Understanding what’s happening

• Supportive adults

• A focus on wellbeing

• Confidence that the young person can take ownership of their recovery

With these in place, the brain can re‑learn healthy patterns—and young people can get back to living the lives they want.
