Slide 3 — What Is the Nervous System?
The nervous system helps your brain talk to your body.
It controls thoughts, feelings, movement, and reactions.
(Icon: brain + nerve lines)
Slide 4 — Two Parts of the Nervous System
- Central Nervous System: brain and spinal cord
-
Peripheral Nervous System: nerves everywhere else
Both work together to help you think, feel, and act.

Slide 5 — Autism & ADHD
Autism Spectrum Disorder (ASD):
- A brain development difference
- Affects social skills, senses, and routine thinking
ADHD:
-
Affects attention, self‑control, and activity
(Use icons for each)
Slide 6 — Mood Disorders
A mood disorder means strong changes in
feelings or emotions over a long time.
Examples:
• Depression: long sadness
• Bipolar: swings from low to high mood
These conditions affect daily life.

Slide 7 — Mood Disorders Are Not Just “Bad Behaviour”
Mood disorders are brain‑based, not a choice.
Someone may look “moody” but their body and brain are affected.
Behaviour is a symptom, not a personal flaw.
Slide 8 — Shared Brain Mechanisms
Neurodevelopmental conditions (like autism/ADHD) and
mood disorders (like depression/bipolar) share brain differences
in:
• Genes
• Brain chemicals (serotonin, dopamine)
• Brain networks
• Stress systems
These help explain why people can have both conditions together.
Slide 9 — Emotional Regulation and the Brain
The brain areas that affect mood and behaviour include:
• Prefrontal cortex — thinking and planning
• Amygdala — emotion and threat detection
Both are involved in neurodivergence and mood symptoms.
Slide 10 — What Happens in the Brain
When brain chemical systems are out of balance:
• Mood can swing between low and high
• Stress response becomes stronger
• Emotional control becomes harder
This can make everyday life harder.
Slide 11 — Why These Conditions Can Co‑Occur
Research shows:
• Autism/ADHD and mood disorders often happen together
• They share brain pathways
• Stress and early experiences affect the brain
So symptoms can overlap.
Slide 12 — Symptoms of Mood Disorders
You or someone else might notice:
• Persistent sadness
• Loss of interest
• Big mood swings
• Trouble sleeping
• Agitation or slow movement
Symptoms affect everyday life.
Slide 13 — Biological Risk Factors
The brain systems involved include:
• Serotonin — mood regulation
• Dopamine — motivation and focus
• HPA stress system — stress response
Disruptions here can cause mood changes.
Slide 14 — Emotional Dysregulation
When you can’t easily calm down, this is called
emotional dysregulation — common in autism, ADHD, and mood disorders.
It can make reactions feel bigger than the situation.
Slide 15 — Treatment & Support
Support may include:
✔ Talking therapy (like CBT)
✔ Medication when needed
✔ Self‑care (sleep, routine, movement)
✔ Supportive relationships
Talking to a professional helps.
Slide 16 — Reflection & Learning
Think about:
• When do emotions feel too heavy?
• What helps you feel calm?
• How can we understand others better?
Slide 17 — Summary
• The nervous system affects mood and behaviour
• Autism, ADHD, and mood disorders are linked
• These conditions share brain biology
• They are not choices or “bad behaviour.”
